5.8.2 Notes on cluster use (limited to Windows only)

• Always perform the operations from the primary node when you are specifying an authentication server or registering JP1 users on a logical host. Be sure to start the JP1/Base service on the logical host before you start JP1 user registration.

• When backing up the definitions on the primary node in a cluster environment, make sure that all the letters in the logical host name that you specify in the jbsgetcnf command match the case of the logical host name in the definitions.

  If you make a mistake, delete the logical host and specify it again.

• Before you delete a logical host, first stop the services of JP1/Base and the programs that require JP1/Base (JP1/IM, JP1/AJS, or JP1/Power Monitor) running on that logical host. If you delete a logical host with a service still active, delete that service in either of the following ways:

  • Recreate a logical host with the same name, and then delete it.

  • Uninstall JP1/Base.

• If you create a logical host with the same host name as the local host, the JP1/Base Event service on the physical host will be deleted if you later delete that logical host. To restore the service, execute the following command:

  jevregsvc -r

• If you cannot start or stop the JP1/Base service, a JP1/Base process might not have completed. In this case, restart the system.

• The JP1/Base LogTrap service is required for using log file traps. This service enables JP1 events converted by log file traps to be registered with event services on physical or logical hosts. You must start the JP1/Base LogTrap service when you start a log file trap to register events with an event service on a logical host even if JP1/Base is not used on the physical host. If you are not using the JP1/Base Control Service, set auto startup for the JP1/Base LogTrap service.

• The startup control function is not available for the services running on logical hosts. The startup control function is only available for the services running on physical hosts. Use cluster software to control startup of services on logical hosts.

• If you are using the event service on the physical hosts, you must edit the event server settings file (conf) for the event service on the physical host of both primary and secondary nodes. The event server settings file (conf) for the event service on the logical hosts defined by the jp1bshasetup.exe command resides in the following location:

  folder-name-specified-on-shared-disk\jp1base\event\conf

• If the JP1/Base service fails to start or stop, JP1/Base processes may remain active in the system. If this happens, restart your computer.

• If you changed the jp1hosts information and communication protocol on a physical host, the settings will be copied when you execute the jp1bshasetup command to set up the logical hosts. If you want the jp1hosts information and communication protocol for the logical hosts to be different from the settings for the physical host, you must re-enter the jp1hosts information and protocol settings for the logical hosts.

• Do not use a disk at the network drive destination as a shared disk for JP1/Base.
