That’s very true for IT teams engaged on Oracle apps corresponding to E-business Suite. Combining DevOps practices with certain building tips for E-business Suite will make complete groups greater valuable and produce more desirable consequences for conclusion clients.

At Flexagon, we’ve been assisting IT groups integrate DevOps practices and equipment into their existing strategies for years – and have deep potential in Oracle know-how, including E-enterprise Suite. We’ve combined our journey with E-enterprise Suite with widely wide-spread DevOps and development most excellent practices to create a list of 10 building assistance for Oracle EBS.

These advice will aid developers standardize their tactics, store time, and cut back errors during construction, testing, and deployment to production. They might also even make a contribution to your efforts to shorten the utility beginning lifecycle and should praise continuous methodologies like continual integration and continuous birth.

most fulfilling Practices for E-company Suite development1. Standardize Naming Conventions

Don’t waste time naming database objects in response to average conventions, then the use of ad hoc naming for file gadget objects. as a substitute, come up with naming conventions that can be easily replicated in scripts, executables, reports, kinds and extra. via taking this approach from the beginning, any out-of-context coding, as an instance in a JIRA ticket, can also be readily understood.

2. song AOL changes to your SCM

building groups most commonly implement AOL adjustments in a shared EBS development atmosphere. for the reason that EBS does not preserve song of revisions of alterations, it is premiere practice to extract every AOL change to an .LDT and checklist the revision as a commit into your source control equipment.

that you would be able to use DevOps tooling to automate the migration of the AOL adjustments the use of the FNDLOAD program. as with every file, you could have visibility into which revisions of your AOLs the place deployed, when, where, and by using whom.

3. Simplify Server administration and in the reduction of complications with Automation

Oracle E-enterprise Suite consists of a variety of servers, features, and workflows. each and every of those components requires diverse handling to cease, start, restart, permit, or disable. Managing these diverse server components isn't a straightforward project. Automating server management is essential for creation environments for right here purposes:

  • choosing which server/element to birth in its place of beginning/stopping/restarting the entire servers
  • cutting back downtime by way of replacing guide tactics with automation
  • Combining with deployment operations to make certain deployed alterations go into impact
  • including approvals and/or notifications to boost control and visibility
  • 4. enrich Versioning for equipment Migration

    alas, it’s ordinary for IT teams emigrate packages, then discover that they aren’t working with the newest version of the code. no longer handiest is that irritating, however also wastes time and extends your software beginning lifecycle.

    instead of struggling to establish which edition of the code you’re working with, make reviewing kit versions less demanding with the aid of including a version code right after the header revision comments in your PL/SQL package. This may also be completed manually via the team or by using DevOps equipment and continuous strategies to make certain here is accomplished every time code is migrated.

    5. structure Your Code

    All coding – no longer handiest packages being readied for migrations – may still observe ordinary protocols. The aim right here is to make the software’s code as simple and readable as possible. Use the case function or indent code invariably to make code fragments convenient and predictable to read.

    whatever code structure you employ, preserve it constant all over your company. everybody may still be in a position to with no trouble view and understand code the usage of the identical system.

    6. be aware of When to use Patch vs. Run edition

    Oracle E-business 12.2 and above comes with versions (Run and Patch). which you could set up your customizations without delay to Run edition or apply to Patch version (online Patching) with the aid of following ADOP patching phases. on-line Patching cycle consists of the following principal phases:

  • prepare
  • follow
  • Finalize
  • Cutover
  • Cleanup
  • online patching reduces downtime and is also known as 0 downtime deployment.

    you could set up adjustments without delay into the run edition. This alternative should be used when alterations are small or when the new on-line patching alternate options aren't adopted.

    7. Create Reusable Frameworks

    Your IT team doesn’t need to spend time getting to know new construction frameworks and specifications until there’s a particular need. So, as you create frameworks to develop your latest Oracle functions, be sure they can also be replicated in future implementations.

    for example, you could enhance a common set of 20 inventory categories that follow a group of naming conventions that can be used across tasks. Use these frameworks throughout teams and with your entire Oracle EBS development tools to create in-apartment necessities that keep time.

    eight. reduce manual, Repeatable projects with Idempotent Database Scripts

    EBS implementations are composed of colossal volumes of database objects and PL/SQL programs. like several EBS object, these definitions need to be synchronized across many environments in your topology. frequently, these objects are migrated across environments with the aid of the DBA by executing DDL/SQL scripts offered by using the construction team.

    one of the greatest challenges in automating the system is managing updates to existing Oracle database objects. here's relatively fundamental for objects which have CREATE OR substitute objects, however that isn't the case for a lot of of the article varieties (e.g. tables, indexes, sequences, and many others.). as an example, you can not execute a create desk statement if the desk already exists. here is most frequently managed by way of writing scripts which are elegant on the state of the object in the goal atmosphere. When it involves automating the manner, this becomes a challenge.

    One technique is to create all DDL/SQL scripts to be idempotent, yielding the identical outcomes even when applied a number of times. in case you observe this observe, that you can maintain a single script it really is used to follow alterations throughout all environments, tune the revision of the script throughout environments, and foster healthier relationships between developers and DBAs.

    There are distinctive recommendations used, which vary by object classification. In most cases, youngsters, the scripts need to investigate the present state and undertake its conduct. For staging tables or stateless objects, effectively shedding and re-developing the object is the most advantageous formula (taking care not to fail if the item does not exist). For stateful objects, akin to permanent tables and sequences, you must deal with insert/replace circumstances, all whereas maintaining any state.

    9. steer clear of challenging Coding

    challenging code or configure? The option appears glaring, however it bears repeating: always configure to prevent problems and further work down the highway.

    In times in case you believe inclined to assign values to your code – either strings or numeric – consider where else you can get this records. If it’s not accessible elsewhere, it's most effective to take the time to strengthen custom profile options, descriptive flex fields (DFF) or key flex fields to extra with no trouble itemize categories.

    10. Automate and neighborhood initiatives together

    Most companies have a couple of environments for numerous purposes like building, device checking out, performance trying out, creation, etc. For successful delivery of features to construction, it's essential that development groups adopt automation practices.

    Automation can also be employed to do a variety of mundane tasks like configuration and code deployment, excellent testing, and more. Automation should still support stay away from errors and drive consistency, which means a discount in downtime and outages. In instances the place projects deserve to be performed all over late nighttime or weekend hours, automation and scheduling can additionally help improve work-lifestyles steadiness.

    As corporations undertake automation, it is a good idea to provide tools for visibility into computerized changes to diagnose problems or for audit tracking for a variety of compliance methods. tools that make it handy to group changes together for merchandising can also also help you control your EBS application start lifecycle that spans anyplace from just a few days to weeks or months.

    Use specifications and Automation to enhance Oracle E-company Suite App building

    Oracle products are extremely really good, and IT groups engaged on them typically boost their personal in-condominium processes in accordance with instructions from Oracle and adventure with E-company Suite. Framing that into requirements and automating processes to cut back guide, repeatable projects and reduce down on errors can vastly improve app construction.

    To complement your in-apartment tactics and most reliable practices, which you can additionally believe adding DevOps equipment with software unencumber automation and other functionality to your IT toolset. These equipment will additional alleviate the burden of guide work in your crew, helping streamline processes and mainstreaming the optimal practices which are already on your tactics.

It doesn’t bode well that HP just bowed out of this company. however that’s how things are this present day.

    at least Oracle is announcing a whole bunch of new services today.

    apart from launching the Elastic Compute Cloud — the identical accurate identify as Amazon, by the way — Oracle is also asserting the brand new Archive Storage service, a File Storage service (NFS v4), a network Cloud service (VPN, and so on.), and even the Oracle Container Cloud for deploying functions packaged up in containers in its place of more normal digital machines.

    Oracle additionally has new huge facts functions accessible in its cloud: the Oracle big information instruction Cloud provider, the Oracle GoldenGate Cloud service, Oracle huge statistics Discovery Cloud service, and the Oracle NoSQL Database Cloud provider.

    however wait, there’s extra! An utility efficiency Monitoring Cloud provider. A Log Analytics Cloud provider. An IT Analytics Cloud carrier.

    last year Oracle announced the thing Storage Cloud provider. Amazon additionally launched its initial storage provider, S3, earlier than releasing its core compute carrier.

    A extra rounded-out portfolio should aid in Oracle’s cloud crusade. It’s no longer Oracle’s core competency, though — databases and, extra currently, hardware are king at the legacy tech seller. Time will inform how massive the Oracle cloud will become.

    Netflix Billing Migration to AWS — Part III | killexams.com real questions and Pass4sure dumps

    In the billing migration blog post published a few weeks ago, we explained the overall approach employed in migrating our billing system to the cloud:

    In this post, the database migration portion will be covered in detail. We hope that our experiences will help you as you undertake your own migrations.

    Have you ever wondered about the elements that need to come together and align to get a complicated database migration right? You might ask, “What makes it complicated?”

    Think of any challenge in database migration and pretty much all of them were there in this migration:

  • Different hardware between source and target
  • OS flavours
  • Migration across heterogeneous databases
  • Multiple datacenters — Netflix data center (DC) and AWS cloud
  • Criticality of the transactional billing data
  • Selective dataset migration
  • Migration of constantly changing data, with minimal downtime
  • Billing, as most of you would agree, is the critical service for any company. The database is the most essential element in any migration and getting it right determines the success or failure of the whole project. The Netflix CDE (Cloud Database Engineering) team was tasked with migrating this critical subsystem database. The following sections describe some of key areas we focused on in order to ensure a successful migration.

    Choice of the database

    Billing applications have transactions that need ACID compliance to process the payment for charged transactions. RDBMS seemed the right choice for the datastore.

    Oracle: As source database was in Oracle, migrating to Oracle in Cloud would avoid cross database migration, simplifying the coding effort and configuration setup. Our experience with Oracle in production gave more confidence with respect to its performance and scalability. However, considering the licensing costs and the technical debt required to migrate legacy data “as is”, prompted us to explore other options.

    AWS RDS MySQL: Ideally we would have gone with MySQL RDS as our backend, considering Amazon does a great job in managing and upgrading relational database as a service, providing multi-AZ support for high availability. However, the main drawback to RDS was the storage limit of 6TB. Our requirement at the time, was closer to 10TB.

    AWS Aurora: AWS Aurora would have met the storage needs, but it was in beta at that time.

    PostgreSQL: PostgreSQL is a powerful open source, object-relational database system, but we did not have much in house expertise using PostgreSQL. In the DC, our primary backend databases were Oracle and MySQL. Moreover, choosing PostgreSQL would have eliminated the option of a seamless migration to Aurora in future, as Aurora is based on the MySQL engine.

    EC2 MySQL: EC2 MySQL was ultimately the choice for the billing use case, since there were no licensing cost and it also provided a path to future Aurora migration. This involved setting up MySQL using the InnoDB engine on i2.8xlarge instances.

    Production Database Architecture

    High availability and scalability were the main drivers in designing the architecture to help the billing application withstand infrastructure failures, zone and region outages, and to do so with minimal downtime.

    Using an DRBD copy in another zone for the primary master DB, helped withstand zone outages, infrastructure failures like bad nodes, and EBS volume failures. “Synchronous replication protocol” was used to enable the write operations on the primary node to be considered completed, only after both the local and remote writes have been confirmed. As a result, the loss of a single node is guaranteed to have no data loss. This would impact the write latency, but that was well within the SLAs.

    Read replica setup in local, as well as cross region, not only met high availability requirements, but also helped with scalability. The read traffic from ETL jobs was diverted to the read replica, sparing the primary database from heavy ETL batch processing.

    In case of the primary MySQL database failure, a failover is performed to the DRBD secondary node that was being replicated in synchronous mode. Once secondary node takes over the primary role, the route53 DNS entry for database host is changed to point to the new primary. The billing application being batch in nature is designed to handle such downtime scenarios. The client connection do not fallback but establish new connections that would point to the new primary after the Cname propagation is complete.

    Choice of Migration Tool

    We spent considerable time and effort in choosing the right tool for the migration. Primary success criteria for the POC was the ability to restart bulk loads, bi-directional replication, and data integrity. We focused on the following criteria while evaluating a tool for the migration.

  • Restart bulk/incremental loads
  • Bi-directional replication
  • Parallelism per table
  • Data integrity
  • Error reporting during transfer
  • Ability to rollback after going live
  • Performance
  • Ease of use
  • GoldenGate stood out in terms of features it offered which aligned very well with our use case. It offered the ability to restart bulk loads in case of failures (a few tables were hundreds of GB in size), and its bi-directional replication feature provided easy rollback from MySQL to Oracle.

    The main drawback with GoldenGate was the learning curve in understanding how the tool works. In addition, its manual configuration setup is prone to human error, which added a layer of difficulty. If there is no primary key or unique key on the source table, GoldenGate uses all columns as the supplemental logging key pair for both extracts and replicats. We found issues like duplicate data at the target in incremental loads for such tables and decided to execute a full load during the cutover for those specific tables with no pre-defined primary or unique key. The advantages and features offered by GoldenGate far exceeded any challenges and was the tool of choice.

    Schema Conversion and Validation

    Since source and target databases were different, with data type and data length differences, validation became a crucial step in getting the data migrated while keeping the data integrity intact.

    Data type mismatch took sometime to fix the issues stemming from it. One example — many numeric values in Oracle were defined as the Number datatype for legacy reasons. There is no equivalent type in MySQL. The Number datatype in Oracle stores fixed and floating-point numbers which was tricky. Some source tables had columns where Number meant an integer, in other cases it was used for decimal values, while some had really long values up to 38 digits. In contrast, MySQL has specific datatypes like Int, bigInt, decimal, double etc and a bigInt cannot go beyond 18 digits. One should ensure that correct mapping is done to reflect the accurate values in MySQL.

    Partitioned tables needed special handling, since unlike Oracle, MySQL expects the partition key to be the part of the primary key and unique key. Target schema had to be redefined with proper partitioning keys to ensure no negative impact on application logic and queries.

    Default value handling also differs between MySQL and Oracle. For the columns with a NOT NULL value, MySQL determined the implicit default value for the column. Strict mode had to be enabled in MySQL to catch such data conversion issues, as such transactions would fail and show up in the GoldenGate error logs.

    Tools for schema conversion: We researched a variety of tools to assist in schema conversion as well as validation, but the default schema conversion provided by these tools did not work due to our legacy schema design. Even GoldenGate does not convert Oracle schema to the equivalent MySQL version, but instead depends on the application owners to define the schema first. Since one of our goals with this migration was to optimize schema, the database and application teams worked together to review the data types, and did multiple iterations to capture any mismatch. GoldenGate will truncate the value to fit the MySQL datatype in case of a mis-match. We relied heavily on data comparison tools and the GoldenGate error logs to help detect mismatches in data type mapping between source and target, in order to mitigate this issue.

    Data Integrity

    Once the full load completed and incrementals caught up, another daunting task was to make sure the target copy correctly maintained the data integrity. As the data types between Oracle and MySQL were different, it was not possible to have a generic wrapper script to compare hash values for the rowkeys to ensure accuracy. There are a few 3rd party tools which do the data comparisons across databases comparing the actual values, but the total dataset is 10 TB which was not easy to compare. Instead, we used these tools to match a sample data set which helped in identifying a few discrepancies related to wrong schema mapping.

    Test refreshes: One of the ways to ensure data integrity was to do the application testing on a copy of the production database. This was accomplished by scheduling database refreshes from the MySQL production database to test. Considering production was being backed by EBS for storage, a test environment was easily created by taking the EBS snapshots off the slave, and doing a point in time recovery into test. This process was repeated several times to ensure data quality.

    Sqoop jobs: ETL jobs and reporting were used to help with data reconciliation process. Sqoop jobs pulled data out of Oracle for reporting purposes. Those jobs were also configured to run against MySQL. With continuous replication between source and target, reports were run against specific time window on the ETLs. This helped in taking out the variation due to incremental loads.

    Row counts was another technique used to compare the source/target and match them. This was achieved by pausing the incremental loads on the target and matching the counts on Oracle and MySQL. Results from row counts were also compared after full GoldenGate load of the tables.

    Performance Tuning

    Infrastructure: Billing application persisted data in the DC on two Oracle databases residing on very powerful machines, using IBM power 7, 32 dual core 64 bit multiprocessors, 750GB RAM, TB’s storage allocated via SVC MCS cluster which is 8G4 cluster with 4GB/sec interface running with RAID 10 configurations.

    One major concern with the migration was performance, as the target database was consolidated on one i2.8xlarge server, using 32 vCPU and 244 GB RAM. The application team did a lot of tuning at the application layer to optimize the queries. With the help of Vector the performance team was able to find bottlenecks and eliminate them by tuning specific system and kernel parameters. See Appendix for more details.

    High performance with respect to reads and writes was achieved by using RAID0 with EBS provisioned IOPS volumes. To get more throughput per volume, 5 volumes of 4TB each were used, instead of 1 big volume. This was to facilitate faster snapshots and restores.

    Database: One major concern using MySQL was the scale of our data and MySQL throughput during batch processing of data by billing applications. Percona provided consulting support, and the MySQL database was tuned to perform well during and after the migration. The main trick is to have two cnf files, one while migrating the data and tweaking parameters like innodb_log_file_size to help with bulk inserts, and the second cnf file for the real time production application load by tweaking parameters like innodb_buffer_pool_instances to help with the transaction real time load. See Appendix for more details.

    Data load: During POC, we tested the initial table load with indexes in on/off combination and decided to go with enabling all indexes before the load. The reasoning behind this was that index creation in MySQL is single threaded (most tables had multiple indexes), and so we instead utilized Golden Gate’s parallel load feature to populate the table with indexes in reasonable time. Foreign key constraints were enabled during the final cutover.

    Another trick we learned was to match the total number of processes executing full and incremental load, to the number of cores on the instance. If the processes exceeded the number of cores, the performance of those data loads slowed down drastically as the instance would spend a lot of time in context switches. It took around 2 weeks to populate 10 TB in target MySQL database with the full loads and have incremental loads catch up.

    Conclusion

    Though the database piece is one of the most challenging aspects of any migration, what really makes a difference between success and failure is ensuring you are investing in the right approach up front, and partnering closely with the application team throughout the process. Looking back on the whole migration, it was truly a commendable effort by different teams across the organization, who came together to define the whole migration and make the migration a great success! Along with the individual and cross team coordination, it’s also the great culture of freedom and responsibility which makes these challenging migrations possible without impacting business.

    Appendix Database Tunables for Bulk Insert Database Tunables for High Transaction throughput Storage

    SQL Monitoring and ASH Analytics in Oracle Enterprise Manager: Q&A with Edward Whalen | killexams.com real questions and Pass4sure dumps

    Sep 20, 2013

    Edward Whalen, an Oracle ACE and the Chief Technologist at Performance Tuning Corporation (www.perftuning.com), was recently featured in an Oracle Enterprise Manager SIG webinar about Oracle Enterprise Manager 12c. Here, he shares his thoughts about the significance of the features provided in the latest release of Enterprise Manager and why they are important to Oracle users.

    Why are you interested in Enterprise Manager 12c?EW: Oracle Enterprise Manager Cloud Control is the latest and greatest Enterprise Manager product from Oracle. In terms of lifecycle management, in terms of managing the database, and in terms of just managing the whole enterprise, it has got some great features.

    In the webcast, I focused on the performance management tools within the Oracle Database, which are ASH Analytics and SQL Monitoring. The reason I was asked to participate is that Oracle Press actually just published a book that I wrote on this topic with my colleagues, Michael New and Matthew Burke, titled, “Oracle Enterprise Manager Cloud Control 12c Deep Dive.”

    Do you use Enterprise Manager?

    EW: I use this technology all the time. I am a database consultant and I mainly focus on performance problems as well as implementations and data migrations, so I use technologies such as Oracle GoldenGate, Data Guard, and Oracle RAC. Oracle Enterprise Manager Cloud Control 12c really provides a lot of capabilities for managing these features of Oracle and gives you the ability to not only manage but monitor and set up alerting. I implement, configure and manage Oracle Enterprise Manager 12c for a number of customers. I love Oracle Enterprise Manager 12c. I am a huge fan of the product.

    Do your customers find it helpful?

    EW: It is extremely useful. The database administrator’s main task in life is to keep the database up and running. So being able to set up proactive alerts and proactive monitoring and pinpoint when something is happening before the user community is calling to complain about it, is really essential to DBAs in order to provide a really great level of service for their customers and end users.

    How did Oracle Enterprise Manager 12c evolve as a product?

    EW: The 12c version of Oracle Enterprise Manager actually came out a full year before the 12c version of the database. The version 12c of Enterprise Manager doesn’t require the 12c version of the database and, in fact, 12c can manage and monitor not only 12c databases but 11g databases, 10g, 9i, and so forth. Prior to Oracle Enterprise Manager Cloud Control, the product was called Oracle Grid Control. Version 10 and version 11 of Oracle Grid Control have been out there for awhile and then with version 12c, Oracle named it Cloud Control.

    The new feature for performance monitoring and performance tuning is a feature only available in Oracle Enterprise Manager called ASH Analytics.  ASH stands for Active Session History so ASH Analytics is what I covered in the webinar – showing how it allows you to dig into what is actually happening in your system on a per-session level even to the point of allowing you to isolate which session and which SQL statement is using the most I/O, or has the greatest CPU utilization, or which ones are holding the most locks.  I am able to dig into those details with the ASH Analytics tool and that is a new feature that was not available in the earlier versions of Grid Control.

    How long have you been a member of the IOUG?

    EW: More than 15 years.

    What has your experience been?

    EW: I love the IOUG. I especially like the IOUG presentations at COLLABORATE because they provide more of the actual down and dirty database administration – really technical information. If you want to learn something about Oracle products and learn about how the DBAs work and what kind of things they run into, you tend to find more about that at COLLABORATE.

    What is it that you will be looking for more information on at Oracle OpenWorld this year?

    EW: I am mainly looking forward to getting more information about the new features in Oracle 12c Database. I also work quite a lot with Oracle GoldenGate and I know they are making a lot of improvements there, so I am planning on attending a few of those sessions as well.

    DevOps for Oracle Apps: 10 E-Business Suite Development Tips | killexams.com real questions and Pass4sure dumps

    The most effective development processes are tailored to the company and product IT teams are working with. The most effective teams develop standardized processes that help reduce errors and speed up the software delivery lifecycle while increasing efficiency for their specific product.

    DevOps spans people, process, and technology, and can be integrated into every IT team. Combined with best practices for each team’s technical landscape, it can create more efficient processes that deliver high-quality software to market in less time.

    That’s especially true for IT teams working on Oracle apps such as E-Business Suite. Combining DevOps practices with specific development tips for E-Business Suite will make entire teams more effective and produce greater results for end users.

    At Flexagon, we’ve been helping IT teams integrate DevOps practices and tools into their current processes for years – and have deep expertise in Oracle technology, including E-Business Suite. We’ve combined our experience with E-Business Suite with general DevOps and development best practices to create a list of 10 development tips for Oracle EBS.

    These tips will help developers standardize their processes, save time, and reduce errors throughout development, testing, and deployment to production. They may even contribute to your efforts to shorten the software delivery lifecycle and will compliment continuous methodologies like continuous integration and continuous delivery.

    Best Practices for E-Business Suite Development 1. Standardize Naming Conventions

    Don’t waste time naming database objects based on standard conventions, then using ad hoc naming for file system objects. Instead, come up with naming conventions that can be easily replicated in scripts, executables, reports, forms and more. By taking this approach from the beginning, any out-of-context coding, for example in a JIRA ticket, can be easily understood.

    2. Track AOL Changes in Your SCM

    Development teams most often implement AOL changes in a shared EBS Development environment. Since EBS does not keep track of revisions of changes, it is best practice to extract each AOL change to an .LDT and record the revision as a commit into your source control system.

    You can use DevOps tooling to automate the migration of the AOL changes using the FNDLOAD program. As with any file, you will have visibility into which revisions of your AOLs where deployed, when, where, and by whom.

    3. Simplify Server Management and Reduce Problems with Automation

    Oracle E-Business Suite consists of many different servers, services, and workflows. Each of these components requires different handling to stop, start, restart, enable, or disable. Managing these different server components is not an easy task. Automating server management is critical for production environments for the following purposes:

  • Determining which server/component to start instead of starting/stopping/restarting all the servers
  • Reducing downtime by replacing manual processes with automation
  • Combining with deployment operations to ensure deployed changes go into effect
  • Adding approvals and/or notifications to increase control and visibility
  • 4. Improve Versioning for Package Migration

    Unfortunately, it’s common for IT teams to migrate packages, then find out that they aren’t working with the latest version of the code. Not only is that frustrating, but it also wastes time and extends your software delivery lifecycle.

    Instead of struggling to identify which version of the code you’re working with, make reviewing package versions easier by adding a version code right after the header revision comments in your PL/SQL package. This can be done manually by the team or by using DevOps tools and continuous processes to ensure this is done each time code is migrated.

    5. Structure Your Code

    All coding – not only packages being readied for migrations – should follow standard protocols. The aim here is to make the application’s code as simple and readable as possible. Use the case function or indent code consistently to make code fragments easy and predictable to read.

    Whatever code structure you use, keep it consistent throughout your organization. Everyone should be able to easily view and understand code using the same system.

    6. Know When to Use Patch vs. Run Edition

    Oracle E-Business 12.2 and above comes with editions (Run and Patch). You can deploy your customizations directly to Run Edition or apply to Patch Edition (Online Patching) by following ADOP patching phases. Online Patching cycle consists of the following major phases:

  • Prepare
  • Apply
  • Finalize
  • Cutover
  • Cleanup
  • Online patching reduces downtime and is also called 0 downtime deployment.

    You can deploy changes directly into the run edition. This option should be used when changes are small or when the new online patching options are not adopted.

    7. Create Reusable Frameworks

    Your IT team doesn’t need to spend time learning new development frameworks and standards unless there’s a specific need. So, as you create frameworks to develop your current Oracle applications, be sure they can be replicated in future implementations.

    For example, you can develop a standard set of 20 inventory categories that follow a set of naming conventions that can be used across projects. Use these frameworks across teams and with all your Oracle EBS development tools to create in-house standards that save time.

    8. Reduce Manual, Repeatable Tasks with Idempotent Database Scripts

    EBS implementations are composed of large volumes of database objects and PL/SQL programs. Like any EBS object, these definitions must be synchronized across many environments in your topology. Often, these objects are migrated across environments by the DBA by executing DDL/SQL scripts provided by the development team.

    One of the biggest challenges in automating the process is managing updates to existing Oracle database objects. This is pretty simple for objects which have CREATE OR REPLACE objects, but that is not the case for many of the object types (e.g. tables, indexes, sequences, etc.). For example, you cannot execute a create table statement if the table already exists. This is most often managed by writing scripts that are dependent on the state of the object in the target environment. When it comes to automating the process, this becomes a challenge.

    One technique is to create all DDL/SQL scripts to be idempotent, yielding the same result even when applied several times. If you follow this practice, you can maintain a single script that is used to apply changes across all environments, track the revision of the script across environments, and foster healthier relationships between developers and DBAs.

    There are different techniques used, which vary by object type. In most cases, however, the scripts must check the current state and adopt its behavior. For staging tables or stateless objects, simply dropping and re-creating the object is the best method (taking care not to fail if the object does not exist). For stateful objects, such as permanent tables and sequences, you must handle insert/update conditions, all while preserving any state.

    9. Avoid Hard Coding

    Hard code or configure? The choice seems obvious, but it bears repeating: always configure to avoid complications and additional work down the road.

    In times when you feel inclined to assign values to your code – either strings or numeric – consider where else you can get this data. If it’s not available elsewhere, it is best to take the time to develop custom profile options, descriptive flex fields (DFF) or key flex fields to more effectively itemize categories.

    10. Automate and Group Tasks Together

    Most organizations have a few environments for various purposes like development, system testing, performance testing, production, etc. For successful delivery of features to production, it is essential that development teams adopt automation practices.

    Automation can be employed to do various mundane tasks like configuration and code deployment, quality testing, and more. Automation should help avoid errors and force consistency, which means a reduction in downtime and outages. In cases where tasks need to be done during late night or weekend hours, automation and scheduling can also help improve work-life balance.

    As organizations adopt automation, it is a good idea to provide tools for visibility into automated changes to diagnose problems or for audit tracking for various compliance processes. Tools that make it easy to group changes together for promotion may also help you manage your EBS software delivery lifecycle that spans anywhere from a few days to weeks or months.

    Use Standards and Automation to Improve Oracle E-Business Suite App Development

    Oracle products are highly specialized, and IT teams working on them typically develop their own in-house processes based on guidelines from Oracle and experience with E-Business Suite. Framing that into standards and automating processes to reduce manual, repeatable tasks and cut down on errors can greatly improve app development.

    To supplement your in-house processes and best practices, you can also consider adding DevOps tools with application release automation and other functionality to your IT toolset. These tools will further alleviate the burden of manual work on your team, helping streamline processes and mainstreaming the best practices that are already in your processes.
