HP Serviceguard Toolkits for Database Replication Solutions User Guide (August 2011)

DescriptionAttributes
Set the IP address used for performing the role switch.
Provide IP address from the subnet that is monitored by
Serviceguard
NOTE: This IP address should not be used to configure
HADR and the HADR must not use this IP for any
purpose. The format of this value should be as follows:
<IP_ADDRESS>:<SUBNET_ADDRESS>
For example: tkit/db2hadr/db2hadr/HADR_IP
10.76.1.200:10.76.1.0, where:
• 10.76.1.200 is the IP address
• 10.76.1.0 is the network subnet.
Suppose there are multiple subnets in the network,
HADR_IP must be defined for all the subnets.
For example: tkit/db2hadr/db2hadr/HADR_IP -
10.76.1.200:10.76.1.0
HADR_IP
tkit/db2hadr/db2hadr/HADR_IP -
10.10.1.50:10.10.1.0
Set it either to [yes ]or [no]. The value must be same for
both the primary and standby packages. If it is set to
RESTORE_ROLE
[yes], the toolkit performs a role switch when both
primary and standby databases are in “peer” state but
the current role of the HADR is different from the
configured role of the package (HADR_ROLE package
attribute) on both nodes. This can happen when the
original primary goes down and a forced role takeover
is done by the standby, and later the primary comes up
as standby. The default value is [no].
This attribute should be set if the database is on a
volume group. Configure this attribute, if the database
is on a local disk.
vg
These attributes are assigned if the package is
configured to failover to another node. Also, when the
ip_address and ip_subnet
package fails over from one node to another node,
client traffic IP and interconnect IP must be moved to the
new node. Both the IPs must be defined in the package.
For a sample package configuration file, see “Sample
package configuration file for the DB2 HADR standby
package” (page 52)
For DB2 Service
Name of the service that Serviceguard monitors while
the package is up. This name must be unique for both
service_name
primary and standby packages in a Serviceguard
cluster. The default value is db2_service.
It is the command line to start the service. $SGCONF/
scripts/ecmt/db2/tkit_module.sh
db2_monitor.
service_cmd
This attribute specifies the number of times the service
was restarted before failing. The default value is [none].
service_restart
This attribute enables Serviceguard to halt the node if
the service fails on that node. The default value is set to
[no].
service_fail_fast_enabled
It is used to determine the duration for which
Serviceguard waits for the service to halt before a
SIGKILL signal. The default value is [300 seconds].
