Hi,
three ideas that might help to find, where the problem is:

  1. If you have shared server, try to connect dedicated. This can easily be done by modifying the tnsnames.ora just by adding (SID=DEDICATED) in the CONNECT_DATA-paragraph in tnsnames.ora We had performance problems occasionally with shared server which could be solved by switching to dedicated server on 8i
  2. Have a look at tables with only a few rows of data. Are they defined parallel? If so, try: ALTER TABLE <TableName> NOPARALLEL on these tables.
  3. When the performance problem occurs again, start enterprise manager and have a look on the database locks. Are there many tables / rows locked?

Well, I don't know if these ideas help, but we had performance problems in the past and these three reasons are the ones I remembered.

Hope that helps.
Bye,
