QUESTION POSED ON: 08 September 2005
Once monthly we run a report of which we have nearly 100,000 records. It takes a long time and the performance is very slow when we run this report.

When I run the SQL trace for the session for the schema in which the report is executed, the size of the trace file becomes very big and so I put off the SQL trace. Please help me to solve this issue.

EXPERT RESPONSE
You can always format a partial trace file with tkprof, and the resulting report may reveal the problem. If it doesn't, I'd suggest that you direct your trace files to a directory on a disk with plenty of room, so that you can trace the entire operation. The tkprof utility can handle enormous trace files with no problem.
