RE: 10gR2 Performance sux!

Hello gurus,

I'm also having performance issues with 10g.  Why would my dictionary
queries take a long time to return... in 9i they used to take seconds,
now they take minutes or they just never come back... This happens when
I query dba_data_files or dba_tablespaces...  The application queries
are not too bad.

Any tips will be appreciated.

The database is in HP-UX11,10.2.0.3, FIRST_ROWS.  (Migrated from
9.2.0.7)  PeopleSoft Financials.

Thanks.

Abraham

Dan Hotka has a presentation called "Tuning SQL when you cannot change
the code!"  

It could help you understand what your options  are for tackling your
problem.  Good luck!
