Termination or restart of REBUILD INDEX
You can terminate and restart the REBUILD INDEX utility.
You can terminate REBUILD INDEX by using the TERM UTILITY command. If you terminate a REBUILD INDEX job, the index space is placed in the REBUILD-pending status and is unavailable until it is successfully rebuilt.
By default, Db2 uses RESTART(PHASE) when restarting REBUILD INDEX jobs. The job starts again from the beginning.
If you restart a job that uses the STATISTICS keyword, inline statistics collection does not occur. To update catalog statistics, run the RUNSTATS utility after the restarted REBUILD INDEX job completes.
