Couple of weeks ago I was analyzing a server for space and noticed SSISDB database was abnormally huge (this Instance was running just a handful of packages). I noticed couple of internal schema tables in SSISDB were huge (with some hundreds of millions of rows), well that’s not right. There should be SSIS Server maintenance job which SQL server creates to purge older entries based on the retention settings right? My immediate action was to check the retention period set and what’s the status of the job. As I suspected, the job was failing (looks like this has been failing since ages) with below error.
The job failed. The Job was invoked by Schedule 9 (SSISDB Scheduler). The last step to run was step 1 (SSIS Server Operation Records Maintenance).
Execute as Login failed for the requested login ‘##MS_SSISServerCleanupJobLogin##’
Next step is to investigate whats up with the user account which the job is complaining about and I noticed ‘##MS_SSISServerCleanupJobUser##’ is orphaned in SSIS database as shown below.
Compare with how it looks on an Instance where this Job is running successfully.
Well, with this the fix is pretty evident, Map the poor fella to the corresponding login (Syntax shown below).
Once this has been done, I kicked off the job and it ran successfully (It took almost 2 hours to finish – had to purge few millions of records) and the subsequent scheduled runs were quick (Just few seconds as expected)
Cheers!
