Problembeschreibung: | |
The command "db2 reorgchk current statistics on table all " on very large databases such as SAP databases involving thousands of tables and associated indexes can take a long time (more than 48 hours) to complete. The same command on v9.5 version will complete in hours. One of the underlying queries involved in the reorgchk logic has been identified as inefficient. Reorgchk logic to get column IDs for Indexes in changed to return all the column IDs in one attempt with fewer joins. | |
