ADF & ADF mobile section: Overview Video published on the ADF Performance Monitor by Frank Houweling

video_pm_overviewA good performance is the key to the success of a web application. Oracle ADF applications are no exception to this rule. ADF performance tuning can be time intensive, costly and quite a challenge when performance issues require developers to delve deep into the inner workings of the ADF framework.

The ADF Performance Monitor is a tool specifically designed for measuring, analyzing, tuning, and checking the performance of Oracle ADF applications. The tool can track and collect crucial (production) performance information of the application’s runtime ADF components that are not standard provided by Oracle. It helps development, QA, and operation teams to detect, analyze and resolve common and less common issues in response times and resource usage of ADF applications. Read the complete article here.

Common WebLogic Problems by Steve Millidge

Oracle WebLogic was originally developed by BEA Systems, a company which was acquired by Oracle in 2008.

Since WebLogic had a much larger user base, Oracle quickly made their intentions to deprecate their own Oracle Application Server (OAS, sometimes referred to as OC4J, the J2EE container component) in favour of WebLogic as their primary offering.

C2B2 have worked with WebLogic since it was owned by BEA and have partnered with both BEA and Oracle. As partners, C2B2 have worked on a wide variety of customer engagements across Oracle’s full middleware portfolio.

Migration from OAS to WebLogic

Oracle Application Server has been deprecated for a number of years now, since Oracle have pushed forward with their plans to offer only WebLogic as their application server of choice. Even so, many businesses are still using OAS or OC4J to run their Java EE applications and are increasingly finding that they need to migrate to WebLogic to avoid being left with legacy infrastructure that they can no longer support effectively.

Fortunately, Oracle has anticipated the need for the process of migration to be as seamless as possible so, for their part, they have put a lot of effort into helping customers migrate their infrastructure. Unfortunately, however much work Oracle might do to help with this migration, there will always be problems or unforeseen circumstances due to the dependencies that applications might have on OC4J which change when moving to WebLogic.

Non-standard technology

A great advantage of buying from a company like Oracle is the ecosystem that you get along with the product. WebLogic, for example, has many other components built by Oracle to improve on the standard Java EE way of doing things. Problems can occur purely down to the vast amount of products and services that Oracle offer. Should you use WebLogic’s JMS implementation, Oracle’s Advanced Queuing (AQ) or Oracle Store-And-Forward for your messaging scenario? How do they differ? Is one better than another, or just better suited to certain applications? It’s clear to see that, although you can be sure that Oracle has a product or component to suit your scenario, it’s a significant task to review even the portfolio of components that come with WebLogic, let alone WebLogic compatible software from Oracle.

Performance Tuning

With considerations like migration and such a range of technologies to use, how can you be sure you’re getting the best performance out of your infrastructure? Consider the scenario – you have a suite of applications, migrated from OC4J which used to use AQ for messaging but now bridge endpoints with Oracle SAF. Are the defaults for the connection pools associated with your data sources optimal for persistent messaging?

It’s very common for users who are not familiar with performance concepts to get completely lost when trying to tune every aspect of their application and server. Should you buy more hardware? Do you need to? Performance issues can get very expensive, whether in terms of buying additional hardware, man-hours to maintain responsiveness or just in terms of your reputation to customers so it should never be an afterthought.

Major Release for Red Samurai Performance Audit Tool v 2.0 by Red Samurai

New major release for our Red Samurai Performance Audit Tool is published early this week. Current update contains many new graphs, providing lots of insight statistics for ADF BC performance and user access.

We are using this tool in every project we run, this really helps to optimize ADF BC and overall ADF application performance. Little bit about history of this tool. First release was developed in August, 2012 - Red Samurai Performance Audit Tool - Runtime Diagnosis for ADF Applications. There was update v 1.1 published this year, just before OOW - Red Samurai Performance Audit Tool - OOW 2013 release (v 1.1). Update v 1.1 included such statistical information as overall transactions and queries going through ADF BC, as well as user access.http://3.bp.blogspot.com/-6ejDDP6dKdo/UlbznZWo-jI/AAAAAAAAKWE/OykPOyQrcA8/s320/6.png

One of the highlights of current update v 2.0 - use of ADF gauge components to visually display each AM performance. We display slow query performance in seconds for minimum, average and maximum slow query processing times: Read the full article here.

Red Samurai Performance Audit Tool – OOW 2013 release (v 1.1)

We are running our Red Samurai Performance Audit tool and monitoring ADF performance in various projects already for about one year and the half. It helps us a lot to understand ADF performance bottlenecks and tune slow ADF BC View Objects or optimise large ADF BC fetches from DB.

There is special update implemented for OOW'13 - advanced ADF BC statistics are collected directly from your application ADF BC runtime and later displayed as graphical information in the dashboard. I will be attending OOW'13 in San Francisco, feel free to stop me and ask about this tool - I will be happy to give it away and explain how to use it in your project.

Original audit screen with ADF BC performance issues, this is part of our Audit console application:
Audit console v1.1 is improved with one more tab - Statistics. This tab displays all SQL Selects statements produced by ADF BC over time, logged users, AM access load distribution and number of AM activations along with user sessions.
Available graphs:

  • Daily Queries  - total number of SQL selects per day
  • Hourly Queries - Last 48 Hours
  • Logged Users - total number of user sessions per day
  • SQL Selects per Application Module - workload per Application Module
  • Number of Activations and User sessions - last 48 hours - displays stress load

SPARC T5-8 Delivers Best Single System SPECjEnterprise2010 Benchmark running WebLogic 12c

SPARC T5-8 ServerOracle produced a world record single-server SPECjEnterprise2010 benchmark result of 27,843.57 SPECjEnterprise2010 EjOPS using one of Oracle's SPARC T5-8 servers for both the application and the database tier.

  • The SPARC T5-8 server ran the Oracle Solaris 11.1 operating system and used Oracle Solaris Zones to consolidate eight Oracle WebLogic application server instances and one database server instance to achieve this result. The IBM system used LPARS and AIX V7.1.
  • This result demonstrated less than 1 second average response times for all SPECjEnterprise2010 transactions and represents JEE 5.0 transactions generated by 227,500 users.
  • The application server used Oracle Fusion Middleware components including the Oracle WebLogic 12.1 application server and Java HotSpot(TM) 64-Bit Server VM on Solaris, version 1.7.0_15. The database server was configured with Oracle Database 11g Release 2.
  • The 8-chip SPARC T5 processor based server is 2.6x faster than the 8-chip IBM POWER7+ processor based server.

Benchmark Description

SPECjEnterprise2010 is the third generation of the SPEC organization's J2EE end-to-end industry standard benchmark application. The new SPECjEnterprise2010 benchmark has been re-designed and developed to cover the Java EE 5 specification's significantly expanded and simplified programming model, highlighting the major features used by developers in the industry today. This provides a real world workload driving the Application Server's implementation of the Java EE specification to its maximum potential and allowing maximum stressing of the underlying hardware and software systems,

  • The web zone, servlets, and web services
  • The EJB zone
  • JPA 1.0 Persistence Model
  • JMS and Message Driven Beans
  • Transaction management
  • Database connectivity

Moreover, SPECjEnterprise2010 also heavily exercises all parts of the underlying infrastructure that make up the application environment, including hardware, JVM software, database software, JDBC drivers, and the system network.

The primary metric of the SPECjEnterprise2010 benchmark is jEnterprise Operations Per Second (SPECjEnterprise2010 EjOPS). The primary metric for the SPECjEnterprise2010 benchmark is calculated by adding the metrics of the Dealership Management Application in the Dealer Domain and the Manufacturing Application in the Manufacturing Domain. There is NO price/performance metric in this benchmark.

Key Points and Best Practices

  • Eight Oracle WebLogic server instances on the SPARC T5-8 server were hosted in 8 separate Oracle Solaris Zones to demonstrate consolidation of multiple application servers. The 8 zones were bound to 4 resource pools using 64 cores (4 cpu chips).
  • The Oracle WebLogic application servers were executed in the FX scheduling class to improve performance by reducing the frequency of context switches.

Red Samurai Performance Audit Tool – Up and Running by Andrejus Baranovskis

It is been some time since we created Red Samurai Performance Audit Tool (in August, 2012). This tool was deployed and it was logging all performance related issues in one of the projects, already for eight months. I thought to share with you how it goes, below you can see the results logged continuously from August, 2012 till now

.

As the project was growing and becoming more complex, performance was going down. But after complexity reached at peak and we

were able to locate performance bottlenecks with audit tool for fixing - performance started to improve in the recent months.

Performance Audit Tool - Runtime Diagnosis for ADF Applications by Red Samurai

To tune ADF application, we need to know exactly what is the reason for performance bottleneck. In Red Samurai we are helping our customer to be happy with ADF. How we do that? Yes - hard quality work (and no bla bla talking) is one of the most important things. But also we use tools - one of such tools is in house developed ADF Runtime Performance Audit tool.
Before blaming ADF is slow, make sure to check the way data is retrieved from DB, also SQL execution performance. I agree, its not always easy to monitor DB/SQL performance for ADF applications. This is the main reason we have developed this tool.
Our tool splits into two parts - Audit Engine (6 KB JAR file) and Performance Audit Dashboard. Customer application needs to include only Audit Engine, the rest happens as magic - information about slow SQL starts to come to dashboard automatically. Tool is universal and runs in development, test and production environments.
Performance Audit Dashboard interface:


Main areas for performance bottleneck and tuning related to DB/SQL in ADF:
1. SQL time execution in DB. While SQL executes, ADF waits for response - we want as fast SQL execution as possible.

2. Duplicate SQL execution. Obviously we want to avoid duplicate SQL execution.

3. SQL count query execution. ADF invokes separate SQL count query to estimate rowset size, this may slow down performance for complex queries.

4. Resultset Fetch size. When fetching lots of records from DB, ADF is using more memory to create and maintain rowset, this potentially slows down application.

5. Passivation/Activation time. One of the slowest operations - need to monitor and avoid as much as possible.
Performance Audit Dashboard offers two charts for performance audit overview:
1. Type of Issues pie chart with selection in time
2. Monthly Issues tracking linear chart
List with issues displays:
1. Issue type
2. SQL execution time
3. Issue details
4. Issue date
5. Application/View Object name related to the issue
6. User name, ADF Web user who was triggering SQL from ADF application
Details section displays more detailed info, such as SQL query or complete info about large rowset fetch.
There is option to change audit parameters on the fly.
We are on track to innovate and improve ADF applications quality, this tool is newest addition to our other tools:
1. Red Samurai MDS Cleaner V2.0
2. JDeveloper 11g Extension to Validate ADF Code Quality
Red Samurai Performance Audit is available free of charge (existing/future Red Samurai customers).
