| 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. |
