I want to know how to generate some statistics on PPMC like users volumetry, objects, memory usage, etc some info like that, is there any command or how can I get it?
Thanks and regards
If you have proper Oracle grants then you can use Oracle STATSPACk utility. More details can be found at:
Or else ask you DBA to share Oracle AWR (or ADR for verison 9i and below) report.
