Getting Optimal Performance from Oracle E-Business Suite

Performance tuning and optimization in E-Business Suite environments can involve many different components and diagnostic tools.  Samer Barakat, Senior Architect in our Applications Performance group, held an OpenWorld 2013 session that covered:

  • Performance triage, analysis and diagnostic tools
  • Optimizing the E-Business Suite application tier, including Concurrent Manager
  • Optimizing the E-Business Suite database tier
  • Optimizing the E-Business Suite on Real Application Clusters (RAC)
  • E-Business Suite on engineered systems, including Exadata and Exalogic
  • Optimizing E-Business Suite data management, including archiving and purging 

Table showing workload management strategy for Concurrent Manager

The Applications Performance group works with the world's largest E-Business Suite customers to isolate and resolve performance bottlenecks. This team has helped tune the E-Business Suite environments of world's largest companies to handle staggering amounts of transactional volume in multi-terabyte databases.  This group also publishes our official Oracle Apps benchmarks, white papers, and performance metrics.

This is an essential set of tips and techniques that all EBS sysadmins and DBAs can use to improve the performance of their environments:

New Whitepaper: Best Practices for Gathering EBS Database Statistics

Most Oracle Applications DBAs and E-Business Suite users understand the importance of accurate database statistics.  Missing, stale or skewed statistics can adversely affect performance. 

Oracle E-Business Suite statistics should only be gathered using FND_STATS or the Gather Statistics concurrent request. Gathering statistics with DBMS_STATS or the desupported ANALYZE command may result in suboptimal executions plans for E-Business Suite.

Our E-Business Suite Performance Team has been busy implementing and testing new features for gathering statistics using FND_STATS in Oracle E-Business Suite databases.  The new features and guidelines for when and how to gather statistics are published in the following whitepaper:

The new white paper, written by Deepak Bhatnagar, Mohammed Saleem, and Andy Tremayne, details the following options for gathering statistics using FND_STATS and the Gather Statistics concurrent request::

  • History Mode - backup existing statistics prior to gather new statistics
  • GATHER_AUTO Option - gather statistics for tables based upon % change
  • Histograms - collect statistics for histograms
  • AUTO Sampling - use the new FND_STATS feature that supports the AUTO option for using AUTO sample size
  • Extended Statistics - use the new FND_STATS feature that supports the creation of column groups and automatic statistics collection on the column groups when table statistics are gathered
  • Incremental Statistics - gather incremental statistics for partitioned tables

The new white paper also includes examples and performance test cases for the following:

  • Extended Optimizer Statistics
  • Incremental Statistics Gathering
  • Concurrent Statistics Gathering

This white paper includes details about the standalone Oracle E-Business Suite Release 11i and 12 patches that are required to take advantage of this new functionality.

Your feedback is welcome

We would be very interested in hearing about your experiences with these new options for gathering statistics.  Please feel free to post your comments here or drop us a line privately.

Do You Need to Bounce E-Business Suite Application Servers Regularly?

A customer recently reported an issue where they needed to bounce their E-Business Suite application tier (mid-tier) servers once a week to resolve stability issues.  This shouldn't be necessary.  We recommend against bouncing EBS application servers regularly.  We've done a lot of work with the E-Business Suite to ensure that regular bounces are not required with the latest releases.

Bouncing your system can reduce performance

It seems counter-intuitive, but bouncing your EBS application tier servers can actually reduce your system's performance rather than improve it.  Oracle E-Business Suite is explicitly designed to minimize round trips between the application tier and the database.  We make extensive use of caches:

  • JDBC cache buffers
  • Java object cache
  • MSD cache for OA Framework pages
  • ... and others
Every time you bounce your mid-tier, you clear these caches.  The longer your mid-tier remains up and running, the better-populated these caches will be, and the better your overall system performance.

Treat the symptoms but miss the real problem

If you need to bounce your EBS application tier server regularly, there's a deeper problem with your environment. 

Here are some issues that can be deceptively-masked by bouncing your EBS mid-tier:

  1. Improperly-tuned heap space (e.g. insufficient heap space, insufficient space for perm generation)
  2. Memory leaks (usually the result of poorly-designed customizations)
  3. Memory hemorrhage (usually the result of infinite loops or poorly-designed custom queries)
  4. Heap space fragmentation (usually the result of running older Java releases)
  5. JDBC connection leaks (resolved in 11.5.10.2 and all R12 releases)

If you're experiencing problems that seem to go away when you bounce your mid-tier, that's a red flag.  You should log a formal Service Request with Oracle Support so that we can help you identify the root cause.

Maintaining Your EBS Environment for Maximum Performance

I think that all E-Business Suite DBAs know that they need to apply a number of interoperability patches when upgrading from one database release to another.  These are documented in our Interoperability Upgrade Notes for a given EBS + database combination.  For example, if you're upgrading Oracle E-Business Suite Release 12 to the latest 11gR2 11.2.0.2 database, you'd apply the patches listed here:
However, I don't think it's as widely-known that there are two other classes of patches that you might need to apply.  These are documented in the following two Notes:
  1. Oracle E-Business Suite Recommended Performance Patches (Note 244040.1)
  2. Database Patch Set Update Overlay Patches Required for Use with PSUs and Oracle E-Business Suite (Note 1147107.1)

Performance benchmark graph for EBS 12 1 2 cpu_load.png


What are E-Business Suite "recommended performance patches"?

Oracle E-Business Suite Recommended Performance Patches (Note 244040.1) is written and maintained by our Applications Performance team.  I've covered this team's responsibilities previously, but to recap: this team is dedicated to optimizing the performance of the E-Business Suite.  They perform all of our E-Business Suite benchmarks and high-volume scalability testing, and they work intensively with our largest E-Business Suite customers in fine-tuning E-Business Suite configurations. 

They've summarized all of their hard-won expertise about performance-related patches in a single document.  A major part of this document covers database patches, but that's not all.  It also covers performance-related patches for:
  • Client tools
  • Applications Technology products and components
  • Financials products
  • Manufacturing and Supply Chain products
  • Human Resources products
  • Sales & Marketing products
This should be your first stop after upgrading your database or if you're trying to nail down a troublesome database performance-related issue.  I consider this mandatory reading for all E-Business Suite DBAs.

Do you want to apply database Patch Set Updates?

Our Server Technologies division began releasing quarterly database Patch Set Updates (PSU) in July 2009.   Patch Set Updates include:
  • Field-tested fixes for critical technical issues that may affect a large number of customers
  • Critical Patch Update fixes
Database Patch Set Updates are optional for E-Business Suite users.  If you choose to use them, database Patch Set Updates may safely be applied to Oracle E-Business Suite Release 11i and 12 environments.  Patch Set Updates are fully compatible and supported for use with the E-Business Suite.  Depending upon the database version and Oracle E-Business Suite release, one or more overlay patches may be required to address conflicts with a specific Oracle Database Patch Set Update.

Database Patch Set Update Overlay Patches Required for Use with PSUs and Oracle E-Business Suite (Note 1147107.1) summarizes the latest overlay patches required when applying Database Patch Set Updates to Oracle E-Business Suite environments running on the 10gR2, 11gR1, and 11gR2 databases.  If you use PSUs with your EBS database, you should review this Note on a regular basis.

Migrating E-Business Suite Application Tier Servers to Linux

If your E-Business Suite environment is hitting the ceiling for performance, you should first tune and optimize it to squeeze the most of your existing hardware.  At some point, you may decide to scale up your application tier with multiple nodes behind a load-balancer.  As part of that process, you might begin considering replacing large SMP servers on your application tier with a pool of servers running Linux on commodity hardware. 

Indeed, this is the architecture that we use to run Oracle's own global E-Business Suite Release 12 implementation.  We have four large Sun database servers fronted by almost 40 application tier servers running Oracle Enterprise Linux (OEL):

gsi_Architecture_Diagram_R12.png

If you're considering a move to Linux for your Apps middle tier servers, you will find the following two Notes invaluable:
You can use these Notes to migrate an Oracle application (middle) tier to any platform that is supported with the Rapid Installs for both Oracle E-Business Suite Release 11i and 12.

The processes described in those Notes provides a certified way to quickly and easily move an existing Oracle application tier system to a different platform, allowing you to utilize different hardware for the Oracle application tier. The migration utility retains the exact Oracle E-Business Suite patch level so that no APPL_TOP/Database synchronization is necessary; this also allows you to retain many customizations.

Running E-Business Suite on Exadata V2

[December 28 2009 update:  E-Business Suite Release 12 is now certified on 11gR2 Database, and can therefore run on Exadata V2.]

The Exadata Database Machine Version 2 was released at OpenWorld 2009 to great fanfare.  Since its unveiling, I've been getting a steady stream of questions from E-Business Suite customers who are intrigued by Exadata V2's potential.

exadata_v2_feature_main.png
All 11gR2 Database Applications are Compatible

The E-Business Suite and other OLTP applications will run on the Exadata V2 system if they're certified with the 11gR2 Database on Linux. 
 
Oracle E-Business Suite Release 11i is certified on the 11gR2 database, so it can run on Exadata V2 today.

We're working on certifying Oracle E-Business Suite Release 12 on the 11gR2 Database right now.  As soon as that certification is completed, Oracle E-Business Suite Release 12 customers will be able to run on Exadata V2.

Apps Benchmarks are Coming Soon

As you can probably imagine, our Applications Performance Group was very excited to get access to one of these amazing machines.  They're working on a detailed set of performance benchmarks for the E-Business Suite on this hardware right now.
 
Oracle's Revenue Recognition rules prohibit me from discussing dates for either the R12+11gR2 Database certification or these benchmarks.  You're welcome to monitor or subscribe to this blog for updates, which I'll post as soon as soon as they're available.

Recommended Database Parameters Updated for EBS 11i

Experienced Apps DBAs know that there are often compelling reasons to tweak the E-Business Suite's database initialization parameters from the defaults.  The master source-of-truth for whether certain parameter settings will help or hurt your EBS environment performance is published here:

Our EBS database architects have just released an updated version of that Note.  Recent updates over the last month include a number of important changes and additions to our recommendations for:

  • Database parameters that should be removed for 10gR2 (10.2.x) databases
  • Database parameters that should be removed for 11gR1 (11.1.x) databases
  • Advanced Queuing (AQ) additions to 10gR1, 10gR2, and 11gR1 recommendations
  • Database initialization parameter sizing recommendations for processes, sessions, db_block_buffers, db_cache_size, sga_target, undo_retention, shared_pool_*, pga_aggregate_target, and total memory required for different numbers of concurrent users
  • New links to related documents

One of our architects wryly observed that this relatively-short list of changes belies the actual importance and impact of the changes to our recommendations. 

Don't be fooled -- these changes are extremely important and can have profound impact on the performance of your Apps database.  All Apps DBAs should spend some quality time comparing your current database settings with the latest recommendations in this document.

Which is Better: Forms Servlet or Socket Mode?

Many products within the Oracle E-Business Suite have screens that are built with Oracle Forms.  Oracle Forms can be run in either servlet mode or socket mode.  Apps 11i is based on Forms 6i and is configured to run in socket mode by default.  Apps 12 is based on Forms 10g and is configured to run in servlet mode by default. What are these modes, and which is better?

What is Forms Servlet Mode?

The Forms Listener Servlet is a Java servlet that delivers the ability to run Oracle Forms applications over HTTP and HTTPS connections. It manages the creation of a Forms Server Runtime process for each client, as well as network communications between the client and its associated Forms Server Runtime process.

The desktop client sends HTTP requests and receives HTTP responses from the web server. The HTTP Listener on the web server acts as the network endpoint for the client, keeping other servers and ports from being exposed at the firewall.

What is Forms Socket Mode?

Initial releases of the Oracle Forms Server product used a simple method for connecting the client to the server. The connection from the desktop client to the Forms Listener process was accomplished using a direct socket connection.  The direct socket connection mode was suitable for companies providing thin client access to Forms applications within their corporate local area networks. For the direct socket connection mode, the client had to be able to see the server and had to have permission to establish a direct network connection.

Although the direct socket connection mode is perfectly suited for deployments within a company’s internal network, it's not the best choice for application deployment via unsecured network paths via the Internet. A company connected to the Internet typically employs a strict policy defining the types of network connections that can be made by Internet clients to secure corporate networks. Permitting a direct socket connection from an external client exposes the company to potential risk because the true identity of the client can be hard to determine.

Servlet Mode Advantages

  1. HTTP and HTTPS traffic is easily recognizable by routers, while socket mode communications is generally considered suspect and treated on an exception basis. 
  2. Existing networking hardware can be used to support basic functions such as load-balancing and packet encryption for network transit.
  3. More resilient to network and firewall reconfigurations.
  4. More robust: servlet connections can be reestablished if network connections drop unexpectedly for Forms, Framework, and JSP-based pages.
  5. Is the only supported method for generic Oracle Forms customers, and therefore is more thoroughly tested by the Forms and E-Business Suite product groups.
  6. Performance traffic can be monitored via tools like Oracle Real User Experience Insight (RUEI).
  7. Socket mode is not supported on Windows-based server platforms.

Socket Mode Advantages

  1. Uses up to 40% less bandwidth than Forms servlet mode.  This may be perceived by Wide Area Network (WAN) users as causing slower responsiveness, depending upon network latency.
  2. Uses fewer application-tier JVM resources than servlet mode, due to fewer TCP turns and lack of overhead associated with HTTP POST handling.

Switching Apps Deployments Between Modes

Due to its numerous advantages, Forms servlet mode is the preferred and recommended deployment model for Forms on the web. 

There may be circumstances where you need to switch between the default Forms modes.  You might wish to switch your Oracle E-Business Suite Release 12 environment to socket mode to improve performance or reduce network load.  You might wish to switch your Apps 11i environment to servlet mode as part of your rollout to external web-based end-users outside of your organization.

If you're running Apps 11i and would like to switch to servlet mode, see:

If you're running Apps 12 and would like to switch to socket mode, see:

Power Tools: Running AutoConfig in Parallel in EBS 12

[Editor's Note:  This is the second of a series of four articles on new AutoConfig features.  These articles are written by members of our AutoConfig Development team.  This is your opportunity to interact directly with that team with your feedback on this tool.]

Our last article discussed ways of tuning your AutoConfig runs via profiling reports that identify bottlenecks during template instantiation.  This article discusses another method of speeding up your AutoConfig runs.  In an R12 E-Business Suite instance, AutoConfig can now be run simultaneously across multiple nodes. This new feature significantly lowers maintenance downtime for multi-node installations. One beta customer of this feature improved the time it takes them to run AutoConfig across their dozen mid tiers by 45%.

How Does AutoConfig's Parallel Mode Work?

Executing AutoConfig in 'parallel mode' engages a locking mechanism so that processes running on individual nodes are synchronized. This mechanism prevents any conflicting updates to the database or the file system. The following figure illustrates AutoConfig running in parallel across multiple nodes:

Diagram showing how AutoConfig runs in parallel on EBS 12

Executing AutoConfig in Parallel Mode

The following command can be used to run AutoConfig in 'parallel mode'

Application Tier

perl $AD_TOP/bin/adconfig.pl contextfile=<CtxFile> [product=<product_top>] –parallel

Database Tier

perl $ORACLE_HOME/appssutil/bin/adconfig.pl contextfile=<CtxFile> –parallel

where

<CtxFile> is the absolute path to the context file
<product_top> is the Product short name

Note that while running AutoConfig simultaneously on multiple nodes, it is very important to ensure that the '-parallel' option is specified while starting AutoConfig on each node to prevent unstable and/or inconsistent filesystem and database states.

Downloading the Latest AutoConfig Engine

Customers on Oracle E-Business Suite Release 12 can obtain this new feature by installing:

This feature is currently not available for Oracle E-Business Suite 11i.  We currently do not have precise plans for delivery of this feature in 11i.

Your Thoughts?

Please let us know about your experience on using this new feature. We'd be very interested in hearing about how long it takes to run AutoConfig on your multi-node installations with and without the 'parallel' option. The new AutoConfig Performance Profiler feature can be used to collect this information. Also let us know of any issues you encounter while using this feature.

Power Tools: Optimizing AutoConfig Performance Through Profiling

[Editor's Note:  This is the first of a series of four articles on new AutoConfig features.  These articles are written by members of our AutoConfig Development team.  This is your chance to get the inside track on these advanced features and provide your feedback directly to our developers.]

Ever wonder what's taking up the time during a given AutoConfig run in your E-Business Suite environment?  Want to optimize the performance of your techstack configuration customizations?  The AutoConfig Performance Profiler gathers data about an AutoConfig run and generates a consolidated AutoConfig profile report in HTML format. The report lists all product tops processed by AutoConfig along with the total instantiation and execution time of the templates within them. A beta customer of this feature helped us fix an indexing issue to allow AutoConfig to run in one third of the time.

The generated performance report allows you to drill down on each product top and view the following:

  • Source and target location of individual templates
  • Time consumed to instantiate or execute each template
  • Execution report for each template

Here's a screenshot of the first few lines of the report:

Mini screenshot of AutoConfig Performane Profiler report

A complete sample performance profiler report can be found here.

Identitying AutoConfig Performance Bottlenecks

This report is useful in analyzing the source of AutoConfig performance bottlenecks. It also helps administrators optimize template customizations (if any). For example, if you have performed customizations to the context variable values or to any of the product templates and you find that AutoConfig is taking more time after the customization, you can use this feature and generate the profiler report to see where exactly the delay is occurring. The profiler report allows you to determine which phase or product took more time to execute.

Then by further clicking on the link for that phase or product, you can see more details at the template level. Going through these details, you can determine which templates are taking an unreasonable amount of time for instantiation or execution. You can use this to verify and optimize your customizations to the templates.

Generating AutoConfig Performance Profiler Reports

To generate the AutoConfig Performance Profiler report, you can run AutoConfig in 'profile mode' by issuing the following command:

Application Tier
 
perl $AD_TOP/bin/adconfig.pl contextfile=<CtxFile> [product=<product_top>] –profile

Database Tier
 
perl $ORACLE_HOME/appsutil/bin/adconfig.pl contextfile=<CtxFile> –profile

where

<CtxFile> is the absolute path to the context file
<product_top> is the Product short name

Note that the -profile option can be used alongside other AutoConfig command line parameters.

Downloading the Latest AutoConfig Engine

Customers on Oracle E-Business Suite Release 12 can obtain this new feature by installing:

Customers on 11i can get this new AutoConfig feature by installing:

Your Thoughts?

We would appreciate if you could share with us your experience on using this new feature. Please post your comments here or email your profiling results to Ivo Dumovic at:

Using Cisco ACE Series Hardware Load-Balancers with EBS 12

Editor's Note:  This certification is an unusual departure from our typical approach to load-balancer support for the E-Business Suite.  In general, we do not perform explicit certifications of specific load-balancers with the E-Business Suite.  It's not possible for us to keep up with the sheer number of different vendors and models available.

Our standard support policy is that standards-compliant load-balancers are assumed to be compatible with the E-Business Suite.  Load-balancers do not require formal testing by our Applications Technology Integration group to be supported for the E-Business Suite.  Our load-balancing-related recommendations are designed to be compatible with all generic load-balancers:

When time and resources permit, we occasionally partner with networking vendors to test unusual or notable new hardware with the E-Business Suite.  Networking vendors are welcome to drop me an email if you'd like to discuss joint projects.

As a rule, we do not recommend a specific vendor's products over any other vendors.  This article should not be considered an endorsement for this particular vendor or networking configuration.  As with all hardware,  customers should perform independent benchmark tests to verify a vendor's claims of improved performance or manageability in E-Business Suite environments.


Oracle and Cisco Systems jointly certified the Cisco ACE Series Application Control Engine with Oracle E-Business Suite Release 12.  Cisco ACE Series Application Control Engine is a new offering from Cisco Systems that has the potential to improve high availability, performance, security, optimized application deployment and lower the cost of ownership for Oracle E-Business Suite R12.  The new ACE platform targets three main aspects, namely manageability, security and performance.  The figure below shows the Virtualization and Role-based Admin features of the ACE module.
