While testing an upgrade path from 8.5 to 9 using the EDMT tool, I noticed that the Purge Jobs were not being built on the SQL instance as I would expect them to. They are missing completely. Just to be sure these Jobs weren't created with a script with the installer I went ahead and installed the Sprawler and brought everything online... still nothing in the way of jobs. I suspected these jobs were typically created by the ICMDBA application when building a NEW instance but just to be certain I build a NEW 9.0 system on a new server and used ICMDBA to create the DB's. Voila, the purge jobs are there. I don't ever recall seeing this issue on previous versions but not to say it didn't exist. I suspect it would have caused signficant issues. I plan to go run through the same process on a 7.5 and/or 8.0 system to see the results.
Bottom line, what should be creating the purge jobs in the case of an Upgrade where EDMT is used. Is there another step that needs to occur? I'll continue to dig but any insight to the purge jobs is appreciated.
