We were running low on space in the MDB, and we have found that there is a lot of space in the MDB taken up by theĀ  usm_system_change* tables. What information is stored in these tables and how can we reduce the amount of space this takes up?


The usm_system_change* tables contain information about all of the actions/transactions which take place in Service Catalog, you'll find some of this information in the "Audit Trail" tab of a request.

You can archive/purge this data using Service Catalog stored procedures. Information about how to do this is in the Service Management documentation:
