Backing up IBM Information Server components [DataStage]

You can back up the components of IBM Information Server to ensure that you can recover your data in the event of hardware failure or other disaster.

During installation, you are prompted to create an installer response file. It is useful to generate this file and store it in a backup location. If you need to reinstall IBM Information Server, you must use the same configuration as the original installation. If you have a copy of the installer file, you can pass the response file to the installer from the command line.

To back up IBM Information Server components:

    Disconnect all user sessions and stop the following IBM Information Server components:

1)     Stop the following services: ASB Agent, Logging Agent, DataStage Telnet Service, DSRPC Server, and DataStage Engine Resource Service.

            Windows: Select Control Panel > Administration Tools > Services or stop the services from the command line using the following commands:

                             sc stop ASBagent
                sc stop Logging Agent
                sc stop dsrpc
                sc stop dstelnet
                sc stop DSEngine

            UNIX: Run the following command to stop the ASBagent and the Logging Agent. This command is located in the /opt/IBM/InformationServer/ASBNode/bin directory.

                ./NodeAgents.sh stop

            You must include the "./" at the start of the command unless the directory in which the command is located is defined in your PATH environment variable.

2)     Stop the WebSphere DataStage services by running the bin/uv –admin –stop command from the WebSphere DataStage engine installation directory which is located, by default, in /opt/IBM/InformationServer/Server/DSEngine. You must run the command as the IBM Information Server administration user (or root) and have executed the dsenv profile.

        Stop WebSphere Application Server. Run the stopServer command from the command line. The stopServer command is located in the following directory by default:

            Windows: C:\IBM\WebSphere\AppServer\bin
            UNIX: /opt/IBM/InformationServer/WebSphere/AppServer/bin

3)    Back up the metadata repository by using database management tools. See the vendor documentation for your database.

4)    If WebSphere Information Analyzer is installed, back up the analysis database used by WebSphere Information Analyzer. See the vendor documentation for your database.

5)    If WebSphere QualityStage is installed, back up the results database used for the WebSphere QualityStage Match Designer output. See the vendor documentation for your database.

    From the command line, use the backupConfig command to back up the WebSphere Application Server profile. The backupConfig command is located in the following directory by default:

        Windows: C:\IBM\InformationServer
        UNIX: /opt/IBM/InformationServer

    Copy the contents of the profile directory to a backup location. In Windows, this directory is located by default in C:\IBM\InformationServer\AppServer\profiles\default\classes. In UNIX, this directory is located by default in /opt/IBM/InformationServer/AppServer/profiles/default/classes.

    Copy the contents of the installation directory and its subdirectories to a backup location. In Windows, this directory is located by default in C:\IBM\InformationServer. In UNIX, this directory is located by default in /opt/IBM/InformationServer.

    WebSphere DataStage jobs might reference external files or libraries on the file system. You must back up these files separately

njoy the simplicity.......
