This section explains how to register a cluster application in scalable operation.
The scalable cluster application performs scalable operation by interconnecting multiple standby cluster applications. Before creating a scalable cluster application, you have to create the standby cluster applications that constitute the components of the scalable cluster application.
When you create a cluster application in a scalable operation, you must first create a cluster application in a standby operation, which is a prerequisite for scalable operation.
If the cluster application of scalable operation is to run on three nodes, create a cluster application of standby operation on each of those nodes (the node is for operation only and has no standby).
When you create a cluster application for standby operation, which is a prerequisite for scalable operation, set up only "Machines[0]."
To create a high-availability scalable cluster application, you must first create a cluster application for standby operation, which is a prerequisite for high-availability scalable operation.
If the cluster application for high-availability scalable operation is 1:1 standby, create a cluster application for 1:1 standby.
To create a cluster application in standby operation that constitutes scalable operation, set "AutoStartUp" to "no." To start the cluster applications automatically when you start RMS, set the value of "AutoStartUp" to "yes" when you create a cluster application as part of scalable operation.
The procedure for setting up the node of a cluster application in a standby operation, which is a prerequisite for scalable operation, is as shown below.

How to set up userApplication configuration nodes |
---|---|
Scalable |
In "Machines[0]," specify a SysNode that is online when the userApplication first starts up. Since standby is not included, you do not need to set up "Machines[1]" and any subsequent items. |
High-availability scalable |
Note that the set-up method varies depending on the topology of the standby operation that is a constituent factor of the cluster application in scalable operation. For information on making this setting, see how to set up the topology of each standby operation. |
For information on how to create standby cluster applications, see "Creating Standby Cluster Applications."
After you complete the setup of standby operation, which is a prerequisite for scalable operation, you must create the cluster application of scalable operation as explained below.
Set up the nodes where the userApplication is configured as follows:
Refer to the following when setting the userApplication attributes:

All of a cluster application of standby operation is displayed with lowercase characters.
If you do not need to set up a startup sequence number, you do not have to perform the procedure described below.
The cluster application for standby operation must be entered entirely in lowercase characters.
The following is an example in which the startup sequence of app1 is the first, followed by app2 and then app3 (app2 and app3 have the same startup sequence number).
When two or more cluster applications for scalable operation are to be created, repeat steps 1. to 12.
