Clearance of aborted instances in workspace in OBPM 10gR3

Question

Hi all,
We have 4000 aborted instances when we see in the OBPM workspace for now. The instances which were aborted later after the 4000 instances cannot be seen now in the workspace when we search for them by the following route:-
Inside the workspace--> Show Filters --> Include the processes whose instances need to be seen --> Status --> Aborted..
How can we delete these 4000 instances from the workspace and how can we see more than 4000 instances aborted in the workspace?
Is there a limit?

Answer 1

Poke around your engine's property settings. One of them (Instances cache / PAPI instance retrieval size) is set to 4000.
As far as getting rid of the aborted instances, look at how often your engine's caducator (the "latency" setting) runs (typically every 48 hours) and how long the instances that have reached the end activity (the instance expiration setting) are looked at (typically every 15 days).
