When you are running a lot of instances of your composites through SOA/BPM 11g in your testing/development environment, you will start to fill up the available space in your database with the logging and auditing information for these instances.  From time to time, you will want to clean up your database by purging the old instance data.

Starting from version 11.1.1.2, we provide a set of SQL scripts in the following location that can be used for just this purpose.

<MIDDLEWARE_HOME>\Oracle_SOA1\rcu\integration\soainfra\sql\purge

If you want to get a feeling for how much free space you have, you might like to use the query in this post, which will produce results like those shown below.

If you are running an earlier version, you can download the scripts as a patch by looking up Oracle Support document number 815896.1.  This document also provides details about how to define a filter so that the scripts will only remove certain instance data, and leave other data untouched.

To remove all old instance data, you can just invoke the scripts like this:

sqlplus dev_soainfra/welcome1 @purge_soainfra_oracle.sql
