5.8.1 Updating an instance environment in a cluster system

To update an instance environment in a cluster system, check the logical host name and instance name, and then update each setting for the instance environment. Perform the instance environment setup on the PFM - RM host at the executing node.

Check the information to be updated in advance by referencing 3.6.2 Updating an instance environment.

Use the jpcconf ha list command to check the logical host name and instance name; use the jpcconf inst setup command to update the instance environment.

To update multiple instance environments, repeat the procedure described below.

To update an instance environment:

1. Check the logical host name and instance name.

   Execute the jpcconf ha list command specifying the service key that indicates the PFM - RM for Platform running in the instance environment that you want to update.

   For example, to check the logical host name and instance name of PFM - RM for Platform, execute the following command:

   jpcconf ha list -key all

   If the set logical host name is jp1-halrmp and the instance name is SDC1, the command displays as follows:

   

2. If services of PFM - RM for Platform are running in the instance environment that is to be updated, stop them from the cluster software.

3. If the shared disk was placed offline (or unmounted) in step 2, use a program such as the cluster software or a volume manager to place it online (or mount it).

4. Execute the jpcconf inst setup command specifying the service key that indicates PFM - RM for Platform in the instance environment that you want to update.

   For example, to update the instance environment where the logical host name for PFM - RM for Platform is jp1-halrmp and the instance name is SDC1, execute the following command:

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

   This example shows execution in the interactive mode, but you can also execute the jpcconf inst setup command in the non-interactive mode. For details about how to execute this command in the non-interactive mode, see 3.1.4(2) Setting up an instance environment.

   If you execute the jpcconf inst setup command in the non-interactive mode, skip step 5.

5. Update the instance environment for PFM - RM for Platform.

   Enter the instance environment settings for PFM - RM for Platform according to the command's instructions. For details about each instance environment setting for PFM - RM for Platform, see 3.6.2 Updating an instance environment. The current settings are displayed (note that the value of RMHost_Password is not displayed). To not change a displayed value, simply press the return key. When all entries have been completed, the instance environment is updated.

6. Restart the services for the updated instance environment from the cluster software.

   For details about how to start and stop services, see the chapter that describes startup and termination of Performance Management in the JP1/Performance Management User's Guide.

Important

To change the value of an item that cannot be updated, you must delete the instance environment, and then re-create it.

For details about the commands, see the chapter that describes commands in the manual JP1/Performance Management Reference.
