Waaaaaaaaaaaaay back since this post was posted, but anyhow. Now on WAS 6.1 in AppServer_Root\properties

There are three property files which control the behavior of the ffdc

filter. The files which are used are based upon the state of the server:

* ffdcStart.properties - used while the server is starting

* ffdcRun.properties - used after the server is ready

* ffdcStop.properties - used while the server is in the process of stopping.
