16.2.4 Registering the JP1/AJS3 service in the cluster software

Register the JP1/AJS3 service in the cluster software to enable failover to be performed. For details about how to register the service, see the documentation for the cluster software.

Note the following when registering the service:

Set the cluster software so that the secondary node can inherit the IP address and shared disk together with the service from the primary node. In addition, set the cluster software so that the application program is also inherited.

Set the cluster software so that JP1/AJS3 starts after the secondary node has inherited the IP address and shared disk, and JP1/Base has started on the secondary node.

Register the following commands in the cluster software:

jajs_start.cluster logical-host-name (command that starts JP1/AJS3)
The command is located in the /etc/opt/jp1ajs2/ directory.
The jajs_start.cluster command executes the following command:

jajs_spmd -h logical-host-name

jajs_stop.cluster logical-host-name (command that stops JP1/AJS3)
The command is located in the /etc/opt/jp1ajs2/ directory.
The jajs_stop.cluster command executes the following command:

jajs_spmd_stop -h logical-host-name

jajs_killall.cluster logical-host-name (command that forcibly stops JP1/AJS3)
This command forcibly stops JP1/AJS3 and releases the resource being used by JP1/AJS3. Executing this command forcibly stops all processes without performing the normal JP1/AJS3 termination processing.
Use this command only in cases such as the following: processing does not terminate even when the jajs_stop.cluster command, which stops JP1/AJS3, is executed.
Note that in the output results of the ps command, a logical host name is added after each process name so that you can identify the logical host to which the process belongs.

If you want to monitor the status of JP1/AJS3 processes so that retries start or stop JP1/AJS3 will be successful, always set the maximum number of retries. If you do not set the maximum number, the number of retries could be unlimited. When you set the maximum number of retries, take into account the time required for normal start or stop processing.

If you use JP1/AJS3 Console, you do not need to register the JP1/AJS3 Console service in the cluster software.
