5.8.3 Notes on cluster use (limited to UNIX only)

• The following procedure shows how to change the language setting for a logical host after setting up the cluster system environment. Shut down JP1/Base and related programs before proceeding.

  1. Change the language setting in the shared file jp1bs_env.conf on the shared disk used by the logical host whose language you want to change.

     For details on how to do so, see 3.4.1 Setting the language (UNIX only).

  2. Create a text file in vi or another editor.

     In this example, the language is set to EUC (Japanese) encoding.

     [logical-host-name\JP1BASE\]

     "LANG"="EUCJIS"

     End the final line with a linefeed character.

  3. Save the text file you created.

     You can give the file any name. In this example, the file name is baselang.conf.

  4. Execute the following command as a user with superuser or JP1/Base administrator permission.

     /opt/jp1base/bin/jbssetcnf baselang.conf

  5. Edit the automatic start script for logical hosts (jbs_start.cluster).

     Set the LANG environment variable of the automatic startup script for logical hosts (jbs_start.cluster) to the same language specified in jp1bs_env.conf in step 1.

     If you manually start a logical host event service without using the automatic start script (jbs_start.cluster), locale information used when the event service is started (for example, the LANG environment variable) must match the language specified in jp1bs_env.conf.

     In the default settings for automatic startup script for logical hosts (jbs_start.cluster), the LANG environment variable is set to C as follows:

     ## Set Environment-variables

     PATH=/sbin:/bin:/usr/bin:/opt/jp1base/bin

     LANG=C

     SHLIB_PATH=/opt/jp1base/lib:/opt/hitachi/common/lib

     If, for example, you specify ja_JP.UTF-8 as the language for jp1bs_env.conf, change the LANG environment variable of the automatic startup script for logical hosts (jbs_start.cluster) as follows:

     ## Set Environment-variables

     PATH=/sbin:/bin:/usr/bin:/opt/jp1base/bin

     LANG=ja_JP.UTF-8

     SHLIB_PATH=/opt/jp1base/lib:/opt/hitachi/common/lib

• If you stop JP1/Base services that support logical hosts, a JP1/Base process might fail to stop. In this case, execute the jbs_killall.cluster command to forcibly stop the process. Note that this command should be used only when JP1/Base processes cannot be stopped with the normal procedure. For details on the jbs_killall.cluster command, see jbs_killall.cluster (UNIX only) in 15. Commands.

• In a cluster system that performs monitoring even during stop processing, modify the command that terminates JP1/Base (the event service and process management including user management), as follows:

  cd /etc/opt/jp1base
  cp -p jbs_stop.cluster.retry.model jbs_stop.cluster
