How to Enable the SAP J2EE Engine to Run in a Cluster

1. Create a resource group for the SAP J2EE engine.

   The SAP J2EE engine resource group is a failover resource group to contain the resource for the SAP J2EE engine and the logical host name for this resource.

   # scrgadm -a -g j2ee-rg

   -a

   Specifies that a new resource group is to be added.

   -g j2ee-rg

   Specifies the name of the resource group to be added. This name can be your choice but must be unique for the resource groups within the cluster. Use this name when configuring the SAP J2EE engine resource in Step 4 in How to Register and Configure an SAP J2EE Engine Resource.

2. Add a logical-host-name resource to the resource group that you created in Step 1.

   # scrgadm -a -L -g j2ee-rg -l j2ee-logical-hostname [ -n netiflist]

   -a

   Specifies that a new configuration is to be added.

   -L

   Specifies that a logical-host-name resource is to be added.

   -g j2ee-rg

   Specifies the logical-host-name resource to be added to the resource group that you created in Step 1.

   -l j2ee-logical-hostname

   Specifies the logical-host name of the SAP J2EE engine resource. Use this name when configuring the SAP J2EE engine resource in Step 4 in How to Register and Configure an SAP J2EE Engine Resource.

   -n netiflist

   Specifies a comma-separated list of network interfaces. All nodes in the node list of the resource group must be represented in the list of network interfaces. Specifying a list of network interfaces is optional. If you omit the list, an attempt is made for each node to discover a network interface on the subnet that the host-name list identifies.

3. Bring online the SAP J2EE engine resource group.

   # scswitch -Z -g j2ee-rg

   -Z

   Specifies that a resource group is to be brought online.

   -g j2ee-rg

   Specifies the name of the resource group to be brought online. This name is the name of the resource group that was created in Step 1.
