Oracle 8.0.5, peoplesoft version 7.51 We have a report that has stopped working due to running out of temporary space.
The first step was to check the explain plan. I compared the explain plans between the production database and a dev database that is approx 6 months old. They were very different. Upon review we found that the production database is now using a different index then the dev system. I made a copy of the prod database, deleted the index, and the explain plan and sql performed the same as the dev system. Question I have is, what would cause the cost based optimizer to choose a different index. The only thing that has changed is the number of rows in the source table. Statistics are up-todate, and I have re-built the indexes in question.
