EM12c Partition Maintenance and Stats
In previous versions of Oracle Enterprise Manager you would call the EMD_MAINTENANCE package to execute certain maintenance tasks such as partition maintenance and statistics gathering. EMD_MAINTENANCE.ANALYZE_EMD_SCHEMA EMD_MAINTENANCE.PARTITION_MAINTENANCE In OEM12c these procedures are replaced by: EMD_MAINTENANCE.GATHER_SYSMAN_STATS EMD_MAINTENANCE.DAILY_MAINTENANCE The daily_maintenance procedure actually calls gc_interval_partitions and gathers stats on Saturday. Not quite sure why that was hardcoded but I guess they figured that monitoring was least likely to be impacted on that day. If the OEM DBMS jobs are down you can also submit them by logging in the to the repository database as SYSMAN and execute the package: Begin emd_maintenance.submit_em_dbms_jobs(); End; / Note that these procedures are automatically run through scheduled jobs once the job_queueue_ processes parameter is set to a value greater than 0.
