I'm running Oracle 9.2.0.4 on Solaris 8.

Lately I found out following on one of db instance in our environment.

select * from v$pga_target_advice returns no rows even though following are set:
pga_aggregate_target, workarea_size_policy=AUTO, statistics_level=TYPICAL

Also v$waitstat,v$filestat,v$tempstat views returns 0 in time related columns..e.g. readtim/writetim/avgiotim..etc.

What could be reason?

Do you think by re-running catalog/cataproc might fix issue?
