How to confirm the result of Gather Schema Statistics and Backup/Restore CBO Statistics
Hi Experts,
Could you share me your advice on the following question.
1. After using concurrent Gather Schema Statistics to gather statistic for one schema, how to confirm whether the gather has succeeded?
2.and also after using concurrent Backup/Restore CBO Statistics to to restore/backup the schema statics,how to confirm whether the restoration/backup has succeeded?
Only by checking if the concurrent run successfully and the value of LAST_ANALYZED is updated? but we found the value of LAST_ANALYZED for some tables aren't updated.
and Run bde_last_analyzed.sql also seems to be a method, but there are so much information,we don't know how to check it.
