However, the problem is that the "sparse extent consolidation" currently uses the same in-place reorg code and process, which does not have a lock timeout. During this phase, REORG RECLAIM EXTENTS on ITC can sit in lock-wait for several hours when there is a long running query holding an 'S' reorg lock on the pages being reorg'ed. As a result, the reorg can hold Db2 transaction logs for several hours, risking database transaction log full.
Instead of having REORG RECLAIM EXTENTS on ITC table to always perform the (in-place) "sparse extent consolidation" implicitly, we need more flexibility and want to see the "in-place" part being decoupled from REORG RECLAIM EXTENTS on ITC tables. The following features are suggested to be added and to allow these options in an auto-reorg policy:
1) Allow REORG INPLACE command on ITC table, and have REORG RECLAIM EXTENTS to do only free extent reclaim, or
2) Add a new option to REORG RECLAIM EXTENTS command to only perform extent reclaim with no "sparse extent consolidation",
