Hi, I am trying to use Management Repository Views from the OEM repository database. In particular, extract TABLESPACE_SIZE, TABLESPACE_USED_SIZE from SYSMAN.MGMT$DB_TABLESPACES view and compare them against a table having thresholds (warn & page) for each database target in OEM, and generate alarms if the TABLESPACE_USED_SIZE is more than the thresholds. The problem is with collection timestamp. It does not happen daily , and hence SYSMAN.MGMT$DB_TABLESPACES does not have the latest data. I opened a SR with Oracle support, but no help so far. Can anyone please clarify : 1. When does the collection happen? Is it configurable ? I see a wide range, spread across a week or so. 2. How can we force collection for all databases at a specific time, before I run the report against the MGMT$DB_TABLESPACES view ? Thanks, Sukumar -- //www.freelists.org/webpage/oracle-l
