Chapter 3

Running SEM-HA

This chapter provides instructions for registering High Availability for Solstice EM (SEM-HA) and running the Solstice EM data services.

The chapter describes the following topics:

3.1 Licensing SEM-HA

Solstice EM must be licensed on all the nodes. For licensing information refer to Chapter 5 in the Solstice EM 4.1 Installation Guide.

3.2 Running SEM-HA

1. The logical host must be online for the SEM-HA to run. Refer to the Sun Cluster Administration Guide and/or manual pages on how to bring a resource online.

2. At the time of system boot, if the resource group containing SEM-HA data service is online, then SEM-HA will start the platform in HA mode. When a node failure is detected, platform will be restarted on the backup node.

3. You can manually stop/abort a running platform at any time. (The Data Service status will still indicate online.)

4. You can manually start the platform by running em_services


Note – The online/offline status of em_services refers to the behavior when a node boots up or when the em_services is switched over to another node. If its state is online, then the platform will be started by the cluster.

The scstat(1M) gives the status of the logical host data service. See scstat(1M) man page for more information.The scswitch(1M) can be used to manipulate the data service and logical host.

3.3 Setting up Internationalization and Localization of SEM-HA

Internationalization is a method of designing and producing software that facilitates easy adaptation to local markets. SEM-HA has been internationalized to support several languages with minimum effort. SEM-HA and all supporting programs have been brought to level four compliance with full support of text and code sets, formats, and collation, messages and text presentation, and Asian language support.

Localization is the process of preparing SEM-HA for a specific locale. The localization process includes the translation of the message files, compiling the translated message files, and installing the message catalog.

The localization and internationalization processes are discussed in the Solaris International Developer's Guide, a Prentice Hall/SunSoft Press book (ISBN 0-13-031063-8).

 

To Localize SEM-HA

To localize SEM-HA, you will need to carry out the following procedure.

1. Login as root or become the superuser.

2. Change directories to where the text files are located.

# cd /install directory/SUNWconn/em/lib/locale/en_US/LC_MESSAGES

3. Translate the messages contained in the Solstice EM application message files for the target locale.

One message file exists for SEM-HA: emhareg.po

4. Create the message file with the following command.

# msgfmt -o em.mo 
*.po

5. Install the message file.

# mkdir 
../LANG/LC_MESSAGES
# cp em.mo 
../LANG/LC_MESSAGES

 

To use Localized SEM-HA

To use the localized SEM-HA, you need to set the following environment variables.

1. First, set the environment variable LANG to your locale. Using Japan (JA) as an example, this would be the following in a C-shell:

hostname% setenv LANG ja

2. The equivalent in a Korn or Bourne shell is:

hostname$ LANG=ja; export LANG

3. Set the NLSPATH environment variable to provide the path to the localized message catalog for the internationalized applications.

hostname% setenv NLSPATH 
<path_to_catalog>/%N
