Setup for Statspack I generally setup a cron job to collect the stats and also make sure that I dont keep ages old stats so I cleanup/purge it after certain days e.g. in following setup I purge all stats which are older than 90 days. This is how I would set up, STEP 1 : Create PERFSTAT tablespace Something like this ... CREATE TABLESPACE PERFSTAT DATAFILE '/oradata_path/perfstat01.dbf' SIZE 2048M
