5.8.2 Updating a monitoring target in a cluster system

To update a monitoring target in a cluster system, check the monitoring target name, and then update the monitoring target. Perform the monitoring target settings on the PFM - RM host at the executing node.

Check the information to be updated in advance by referencing 3.1.4(3) Setting the monitored host for Windows and 3.2.4(4) Setting the monitored host for UNIX.

Use the jpcconf target list command to check the monitoring target name; use the jpcconf target display command to check the settings for the monitoring target; use the jpcconf target setup command to update the monitoring target.

Note: When you update the monitoring target, there is no need to stop services of PFM - RM for Platform.

To update multiple monitoring targets, repeat the procedure described below.

To update the monitoring target:

Check the name of the monitoring target.

Execute the jpcconf target list command specifying the service key that indicates the PFM - RM for Platform that is monitoring the target to be updated, the logical host name, and the instance name.

For example, to check the name of the monitoring target for the PFM - RM for Platform whose logical host name is jp1-halrmp and instance name is SDC1, execute the following command:

jpcconf target list -key RMPlatform -lhost jp1-halrmp -inst SDC1

When this command is executed, the following information is displayed:

Output example:
```
Targets:
targethost1
targethost2
Groups:
All
```
Check the settings for the monitoring target.

Execute the jpcconf target display command specifying the service key that indicates the PFM - RM for Platform that is monitoring the target to be updated, the logical host name, the instance name, and the monitoring target name.

For example, to check the settings for the monitoring target whose name is targethost1, logical host name is jp1-halrmp, and instance name is SDC1, execute the following command:

jpcconf target display -key RMPlatform -lhost jp1-halrmp -inst SDC1 -target targethost1
If the shared disk is in offline status (or is unmounted), use a program such as the cluster software or a volume manager to place it online (or mount it).
Execute the jpcconf target setup command specifying the service key that indicates the PFM - RM for Platform that is monitoring the target to be updated, the logical host name, the instance name, and the monitoring target name.

For example, to update the monitoring target whose name is targethost1, logical host name is jp1-halrmp, and instance name is SDC1, execute the following command:

jpcconf target setup -key RMPlatform -lhost jp1-halrmp -inst SDC1 -target targethost1

This example shows execution in the interactive mode, but you can also execute the jpcconf target setup command in the non-interactive mode. For details about how to execute this command in the non-interactive mode, see 3.1.4(3) Setting the monitored host.

If you execute the jpcconf target setup command in the non-interactive mode, skip step 5.
Update the monitoring target of PFM - RM for Platform.

Enter the monitoring target information for PFM - RM for Platform according to the command's instructions. For details about the monitoring target information for PFM - RM for Platform, see 3.6.3 Updating a monitoring target. The current settings are displayed (note that the value of Password is not displayed). To not change a displayed value, simply press the return key. When all entries have been completed, the monitoring target is updated.

Important: To change the value of an item that cannot be updated, you must delete the monitoring target information, and then re-create it.
