Using the DB2 database Toolkit in a Serviceguard Cluster in HP-UX Release README: B.06.00

PARTITION_NUMBER: The list of the logical database
partitions that
participate in a DB2 instance and are
intended to
run on single server. Physical partitions
should
be packaged separately.
MONITOR_PROCESSES: This is the failsafe list of critical
processes of
a DB2 instance.
Note:-These processes must not be running
after DB2
is shutdown. If the processes are
still
running they will be killed by
sending a
SIGKILL.
MAINTENANCE_FLAG: This variable will enable or disable
maintenance
mode for DB2 package. By default this is
set to
"yes". In order to disable this
feature
MAINTENANCE_FLAG should be set to
"no". When
DB2 Database needs to be maintained
then a
file "<package directory>/db2.debug" needs
to be
touched. During this maintenance period DB2
database
instance's process monitoring is paused.
Even if
DB2 instance is brought down, package will
not be
failed over to the standby node. To
continue
monitoring and come out of the maintenance
mode,
you should remove the file "db2.debug"
from the
package configuration directory. It is
user's
responsibility to ensure that db2
instance is
properly running after the maintenance
phase.
NOTE: Setting MAINTENANCE_FLAG to "yes" and touching the db2.debug
file in
