Purging terminated Instants in SOA

Question

Hi
I want to Purge BPEL Instances that Terminated on successful completion. I have searched a lot but could not find scenario like this. But this tutorial looking good
Delete large numbers of instances in Oracle SOA Suite 11g 
Under "purging instances of multiple composites using STATE filters" the writer has mentioned the following stats
FILTER.STATE := fabric.STATE_COMPLETED_SUCCESSFULLY;
--FILTER.STATE := fabric.STATE_RECOVERY_REQUIRED;
--FILTER.STATE := fabric.STATE_COMPLETED_SUCCESSFULLY;
--FILTER.STATE := fabric.STATE_FAULTED;
--FILTER.STATE := fabric.STATE_TERMINATED_BY_USER;
--FILTER.STATE := fabric.STATE_SUSPENDED;
--FILTER.STATE := fabric.STATE_STALE;
--FILTER.STATE := fabric.STATE_UNKNOWN;
I what meant by FILTER.STATE := fabric.STATE_TERMINATED_BY_USER can i use this to purge successful completed composite with terminated condition
Please help me in this regards or any other alternative
Thanks

You can use a Java API (documented here: http://docs.oracle.com/cd/E21764_01/integration.1111/e10226/soaadmin_apimanage.htm) to remove composite instances, either from Java or Jython, of course. I prefer this to the OOTB purge scripts because they're fairly opaque and after working in middleware for the past 14 years my mind doesn't easily run to database internals so the chance to use a Java facade onto what's actually in SOAINFRA is welcome.
FWIW, I've got a Jython script that deletes instances within specified timestamps that are not running or needing recovery. One caveat is that the list of states in the CompositeInstance interface is not the same as the list in the database (which you can read here: https://blogs.oracle.com/ateamsoab2b/entry/list_of_all_states_from).
