Verifying the SAP DB Installation and Configuration

Before you install the Sun Cluster HA for SAP DB packages, verify that the SAP DB software is correctly installed and configured to run in a cluster. This verification does not verify that the SAP DB application is highly available because the Sun Cluster HA for SAP DB data service is not yet installed.

How to Verify SAP DB Installation and Configuration on Each Node

Perform this procedure on each node that can master the SAP DB resource group.

1. Log in as superuser to a node that can master the SAP DB resource group.

2. Switch the SAP DB resource group to the node that you logged in to in Step 1.

   # scswitch -z -g sapdb-rg -h node

   -z

   Specifies that the node that masters a resource group is to be switched

   -g sapdb-rg

   Specifies that the SAP DB resource group is to be switched to another node

   -h node

   Specifies the node to which the SAP DB resource group is to be switched

3. Confirm that the SAP DB database can be started and be stopped.

   1. Become the OS user who administers the SAP DB database.

      # su - os-sapdb-adm-user

      os-sapdb-adm-user

      Specifies the UNIX user identity of the OS user who administers the SAP DB database. This user's home directory contains the .XUSER.62 file that was created during the installation and configuration of SAP DB. For more information, see Installing and Configuring SAP DB. You specify this user when you set the DB_User extension property as explained in How to Register and Configure an SAP DB Resource.

   2. Start the SAP xserver.

      # x_server start

   3. Manually start the SAP DB database instance on the node that you logged in to in Step 1.

      # dbmcli -U sapdb-adm-key db_online

      -U sapdb-adm-key

      Specifies that the dbmcli command is run with the user key of the database user who administers the SAP DB instance. This user key is created during the installation and configuration of SAP DB. For more information, see Installing and Configuring SAP DB. You specify this user key when you set the User_Key extension property as explained in How to Register and Configure an SAP DB Resource.

   4. Confirm that the SAP DB database instance is started.

   5. Manually stop the SAP DB database instance.

      # dbmcli -U sapdb-adm-key db_offline

      -U sapdb-adm-key

      Specifies that the dbmcli command is run with the user key that you used for starting the database in Step c

   6. Confirm that the SAP DB database instance is stopped.
