Re: Re: question on tkprof

Three options:

• use the "Hotsos Profiler" trace analysis tool from http://www.hotsos.com
• use the "itrprof" trace analysis tool from http://www.ubtools.com
• copy a TKPROF executable from an Oracle9i release and run (through SQL*Net!) against your earlier database. Not guaranteed to work, of course, but it could be worth a try...
  • if you are on UNIX and are comfortable with the "make" utility, copy the "s0kvpf.o" object file from the "$ORACLE_HOME/rdbms/lib" on an Oracle9i software distribution and copy it to your own target RDBMS version's "$ORACLE_HOME/rdbms/lib" (making sure to save the existing file first, of course). Then, attempt to relink the TKPROF executable using "make -f ins_rdbms.mk itkprof" from the "OH/rdbms/lib" directory...

Cary Millsap and Jeff Holt (of www.hotsos.com) have found lots of anomalies in Oracle ".trc" files, so they have compensated for these in their tool and Cary is about to publish a book that explains many of them. Gazi Unal-Bilism of www.ubtools.com has had his itrprof tool available as a service from the web and has been including WAIT information in his analysis for quite a while...

Of course, the third option is entirely at your own risk. Whether that is attractive to you or not makes for an interesting discussion on its own! :-)

the user which you are running EXPLAIN PLANs into (using the EXPLAIN= option) does not have permission or space-quota to create a small temporary table in which to place EXPLAIN PLAN output. Check the permissions of the user you are specifying; log into SQL*Plus using the same user and try to create a small dummy table...
