DB2 FOR LUW / DB2FORLUW / 970 - DB2

Deactivate takes a long time to complete on HADR standby if one 
of the redo workers is working on a queue having the minLSN 
record, it never leaves the queue to check if an interrupt has 
arrived. 
 
When the redo master thread gets the interrupt, sets a flag for 
the redo workers to see, but the redo workers can see it only if 
they are trying to find a queue to work on. If the redo worker 
is already working on a queue and happens to have the minLSN 
record on the queue, it does not check for the flag hence does 
not know that the interrupt has arrived.

* PROBLEM DESCRIPTION:                                         * 
* Deactivate takes a long time to complete on HADR standby.The * 
* typical symptom is that one of the db2redow                  * 
* workerthread/process will keep on working and the deactivate * 
* willwaitfor that to complete.If a db2trc is taken of that    * 
* process/thread, it'll show thatitis working and processing   * 
* records.At this point, the only way to come out of this      * 
* situationquickly is to kill the instance using db2_kill or   * 
* wait tilldb2redow thread has completed its work.LOCAL        * 
* FIX:db2_kill to kill the instance. Please note, that restart * 
* oftheinstance will now take time as recovery will start      * 
* rightfromthe point where it got interrupted by the kill      * 
* signal.                                                      *
