Setting up an Oracle-Only Backing Store : Handling Deleted Entities

Handling Deleted Entities
When entities are deleted from the cache, they are added to a script that is run at system startup. The script removes the deleted entities from the backing store.
Depending on the number of deleted entities, the cleanup step can make system startup unacceptably slow.
Manual Deletion of Deleted Entities
To deal with slow startup, you can run the yourname_delete.sql script manually, to reduce the number of entities that have to be processed at startup. This script is generated by the be-oradeploy utility. See Generated SQL Scripts for a list of scripts generated by the utility.
Disabling Deleted Entity Cleanup at System Startup
You can also disable the cleanup action performed at system startup and perform all cleanup manually, using the deletion script.
Add the following property to the TRA file and set it to false:
be.engine.cluster.cleanup
