DB2 STANDBY REPLAY DELAY caused by Offline reorg

IBM case: TS008415413

When an OFFLINE REORG is submitted on Primary, the REPLAY on STANDBY (both Principal and Auxiliary) applies the transactional logs till the BUILD phase. When the reorg moves to recreate or updates the INDEXES, the REPLAYS stops on STANDBY. When a large table is reorged with 1-5 billions records or few indexes, the STANDBY REPLAY stays on hold for hours; After the reorg is finished, the REPLAY starts and hence STANDBY are not available for hours, which bring a HUGH risks to the availability of the database and big RISKS to the application, specially when it is concern to the national security.

    I have helped this customer / DBA extensively test offline REORGs and have observed this behavior: extreme delay in replaying the reorg to the HADR standby. Testing was done under Db2 11.5.7.0. special build #18100 running on AIX 7.2

    Note that this RFE is for tables that have indexes but do not have a clustering index (which will have a known offline reorg replay delay).

    Comments:
    -- The reorg commands incurring this lengthy replay delay do not include indexes in the REORG command and do not include the RESETDICTIONARY in the REORG command.
    -- The REORG commands issued were simple REORG <tablename> statements.
    -- Tests were also performed including "CLEANUP ONLY ALL" which did not improve the HADR replay performance.
