6.7 Setting Up Cluster Applications
This section explains how to set up a cluster application.
You can use any one of the nodes of the cluster system for the settings described in this section.
Cluster application setup flow
The setup flow for a cluster application is explained for each topology, below.
For information on these topologies, see "Determining the Cluster System Operation Mode."
1) 1:1 standby for standby operation
Set up 1:1 standby for standby operation as follows.

2) Mutual standby for standby operation
Set up mutual standby for standby operation as follows.

- To create two cluster applications, repeat steps 2. to 3.
3) N:1 standby for standby operation
Set up N:1 standby for standby operation as follows.

4) Cascaded standby operation
Set up cascaded standby operation as follows.

5) Priority transfer of standby operation
Set up the priority transfer of standby operation as follows.

- To create two or more cascade cluster applications, repeat steps 2. and 3.
- Establish an exclusive relationship between the cluster applications.
For details on exclusive relationships, see "Exclusive Relationships Between Cluster Applications."
Example) For priority transfer with two cascade cluster applications, repeat steps 2. and 3. two times to create two cascade cluster applications.
6) Scalable operation
Set up a scalable operation as follows.

- Before you create cluster applications as part of scalable operation, create cluster applications in standby operation that act as the constituent factors of the cluster applications in scalable operation. To create cluster applications in standby operation, repeat steps 2. to 3.
Example 1) For scalable operation with three nodes, repeat steps 2. and 3. three times to create three cluster applications of standby operation.
Example 2) For high-availability scalable 1:1 standby (standby operation), repeat steps 2. and 3. once to create 1:1 standby cluster applications.


- Set up the cluster application and resources based on the cluster application and resource information in the "Cluster Application Worksheet," which was created in the planning stage. If you need to change the cluster application after it is created, the worksheet is helpful.
- You cannot share one resource with multiple userApplication.
- Generate and Activate process fail if RMS is running. Using Cluster Admin or hvdisp, you need to confirm that RMS has not started before creating a cluster application. If RMS has already started, stop RMS from Cluster Admin or execute the "hvshut" command to stop RMS on all the nodes of the cluster system. For details on "hvdisp" and "hvshut", see the pages of these commands respectively.
- Set up "remote file copy" and "remote command execution" for the RMS Wizard. See the notes on "Setting Up CF and CIP."
If the cluster interconnect is not protected by security, cancel the "remote file copy" and "remote command execution" settings on all the cluster nodes after setting up the cluster applications.
