****************************************************************
* PROBLEM DESCRIPTION: *
* The problem is due to internally changing a structure *
* without holding the latch for it. *

| Local Fix: |
Set Statement monitor switch to OFF (DFT_MON_STMT) and make sure
that the Statement Monitor switch is not turned on for the
sessions (db2 get monitor switches).
Note that db2top -s Statement option has Statement Monitor
switch turned on by default so using db2top to monitor
Statements will make the system vulnerable to this APAR. |
