Attributes | Description |
HADR_IP | 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 |
| tkit/db2hadr/db2hadr/HADR_IP - |
| 10.10.1.50:10.10.1.0 |
RESTORE_ROLE | Set it either to [yes ]or [no]. The value must be same for |
| both the primary and standby packages. If it is set to |
| [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]. |
vg | This attribute should be set if the database is on a |
| volume group. Configure this attribute, if the database |
| is on a local disk. |
ip_address and ip_subnet | These attributes are assigned if the package is |
| configured to failover to another node. Also, when the |
| 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 |
service_name | Name of the service that Serviceguard monitors while |
| the package is up. This name must be unique for both |
| primary and standby packages in a Serviceguard |
| cluster. The default value is db2_service. |
service_cmd | It is the command line to start the service. $SGCONF/ |
| scripts/ecmt/db2/tkit_module.sh |
| db2_monitor. |
service_restart | This attribute specifies the number of times the service |
| was restarted before failing. The default value is [none]. |
service_fail_fast_enabled | This attribute enables Serviceguard to halt the node if |
| the service fails on that node. The default value is set to |
| [no]. |
service_halt_timeout | 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]. |
