Subject Re: Shutting down CAS PGE workflow instances
Date Fri, 14 Oct 2011 01:55:11 GMT
Hey Sheryl,

We don't have a tool (other than downloading http://getopt.org/luke/ and 
deleting the record from the lucene workflow inst. repo) to remove entries 
from the workflow inst. repo. However, the way I usually just do it is blow 
away the inst. repo directory, restart WM and just go from there. 

Cheers,
Chris
