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!
