Clean operation

For ESE versions earlier than version 8, the agent uses the db2nkill program with instance owner's ID to kill the instance processes owned by the $DB2InstOwner for the instance or database partition.

• For ESE single-partition instance, the agent uses the following command to kill a DB2 instance:

  su $DB2InstOwner -c "$InstHome/sqllib/bin/db2nkill 0"

• For ESE multi-partition instance, the agent uses the following command to kill a DB2 database partition in the SMP configuration:

  su $DB2InstOwner -c "$InstHome/sqllib/bin/db2nkill nodenum

  $NodeNumber"

For ESE version 8, the agent uses the db2gcf program to kill a DB2 database partition with either the ESE single-partition instance configuration or the ESE multi-partition instance in SMP or MPP configuration. The command is:

 su $DB2InstOwner -c "$InstHome/sqllib/bin/db2gcf -k -i

$DB2InstOwner -p $nodenum"
