Which part of reading the Oracle installation docs is causing a problem?

http://docs.oracle.com/DOCS_DOT_PDF_Storage/a90351.pdf

clearly states: SHMMNI = 512 ... you have 100 and SHMSEG = 32 ... you have 10

and I stopped looking for discrepancies after two so there are likely lots more.

Please read and follow the installation guide on the CD and also at http://docs.oracle.com

While this may not solve your speed problem it will keep you from collecting ORA-03113's.

With respect to speed one needs to ask things like have you been using DBMS_STATS to run and maintain current statistics. Have you run EXPLAIN PLAN and TKPROF? Have your run DBMS_PROFILER? Until you have there is little that can do to help you other than to suggest that you need to start with the basics.
