ProcedureHow to Verify an SAP Failover Application Server

Use this procedure to verify SAP and the database installation for the failover application server. Perform the following steps on all the potential nodes on which the failover application server can run.

  1. Create the failover resource group to hold the network and application server resources.


    #  clresourcegroup create sap-as-fo-resource-group
    Note –

    Use the -p option to the clresourcegroup command to select the set of nodes on which the SAP application server can run.


    # clresourcegroup create sap-as-fo-resource-group [-p nodelist]

  2. Verify that you added to your name service database all the network resources that you use.

  3. Add a network resource (logical hostname) to the failover resource group.


    # clreslogicalhostname create -g sap-as-fo-resource-group \
 -d sap-as-fo-logical-hostname
    Note –

    If you require a fully qualified hostname, you must specify the fully qualified name with the -h option and you cannot use the fully qualified form in the resource name.

  4. Enable the resource group.

    Run the clresourcegroup(1CL) command to move the resource group into a managed state and bring the resource group online.


    # clresourcegroup online -emM sap-as-of-resource-group

  5. Log in to the cluster member that hosts the application server resource group.

  6. If you are you using the MaxDB database, create a .XUSER.62 file in the SAPSIDadm home directory as described in How to Install and Configure MaxDB in Sun Cluster Data Service for MaxDB Guide for Solaris OS. Verify that the .XUSER.62 file is correctly configured by using the -d option of the R3trans command. You must be an SAPSIDadm user to perform this verification.

    If you are not using the MaxDB database, proceed to the next step.

  7. Manually start the application server.

  8. Start the SAP GUI by using the logical hostname, and verify that SAP initializes correctly.

  9. Manually stop the application server.

  10. Switch this resource group to another cluster member that can host the application server.


    # clresourcegroup switch -n nodesap-as-fo-resource-group

  11. Repeat Step 5 through Step 8 until you verify startup and shutdown of the application server on each cluster node that can host the application server.
