Oracle SOA Suite: Want performance? Don’t log so much and clean up your database! by Maarten Smeets



The Oracle SOA Suite infrastructure, especially composites, use the database intensively. Not only are the process definitions stored in the database, also a lot of audit information gets written there. The SOA infrastructure database, if not well managed, will grow and will eventually have detrimental effects on performance. In this blog post I will give some quick suggestions that will help you increase performance of your SOA Suite infrastructure on the database side by executing some simple scripts. These are some suggestions I have seen work at different customers. Not only do they help managing the SOA Suite data in the database, they will also lead to better SOA Suite performance.

Do not log too much!

Less data is faster. If you can limit database growth, management becomes easier.

  • Make sure the auditlevel of your processes is set to production level in production environments.
  • Think about the BPEL setting inMemoryOptimization. This can only be set for processes that do not contain any dehydration points such as receive, wait, onMessage and onAlarm activities. If set to true, the completionpersistpolicy can be used to tweak what to do after completion of the process. For example only save information about faulted instances in the dehydration store. In 12c this setting is part of the ‘Oracle Integration Continuous Availability’ feature and uses Coherence.

Start with a clean slate regularly

Especially for development environments it is healthy to regularly truncate all the major SOAINFRA tables. The script to do this is supplied by Oracle: MW_HOME/SOA_ORACLE_HOME/rcu/integration/soainfra/sql/truncate/truncate_soa_oracle.sql

The effect of executing this script is that all instance data is gone. This includes all tasks, long running BPM processes, long running BPEL processes, recoverable errors. For short everything except the definitions. The performance gain from executing the script can be significant. You should consider for example to run the script at the end of every sprint to start with a clean slate. Read the complete article here.
