6.6.2.1 Creating Standby Cluster Applications

This section explains how to register standby cluster applications to RMS by using the "userApplication Configuration Wizard."

The flow of the process for registering the Standby cluster applications is shown below.

[Flow of cluster application registration]

Starting cluster application creation

At the top menu of the "userApplication Configuration Wizard," select Create userApplication.

[Top menu of userApplication Configuration Wizard]

Click Next to go to the "Set up userApplication name and operation method" screen.

Setting the userApplication name and the operation method

Enter the userApplication name and the operation method.

[Set up userApplication name and operation method]

userApplication name

Specify the name of the cluster application.

Specify the input character string using up to 18 characters starting with an alphabetic letter and consisting of only alphanumeric characters and "_" (underscore).

Operation method

Specify Standby (standby operation) or Scalable (scalable operation) as the operation method of the cluster application.

• Standby

  This is the default operation method. When multiple SysNode are selected, "priority" values must be set.

• Scalable

  This is only for the cluster application resources displayed in Resource Selection. The priority does not need to be set even if multiple SysNode are selected.

After completing the setup, click Next to go to the "Select SysNode" screen.

Selecting a SysNode

Select the SysNode in which the cluster application is to be configured.

[Select SysNode]

Available SysNode

Contains names of available SysNodes that belong to the specified RMS configuration.

Selected SysNode

The name of the SysNode in which the cluster application is to be operated. The priority of SysNode is determined by the sequence in which SysNode are listed in this box. SysNode displayed at the top of the list becomes the Online SysNode when userApplication is started.

From Available SysNode, select the SysNodes in which the cluster application is to be built, and then click Add. To add all listed SysNodes, click Add all. To remove a SysNode, select the SysNode to be removed from Selected SysNode, and then click Remove. To remove all listed SysNodes, click Remove all.

After completing the setup, click Next to go to the "Set up attribute" screen.

Setting cluster application attributes

Refer to the items below when setting up the cluster application attributes:

• To start the cluster application automatically when the cluster is started

  Set "AutoStartUp" to "Yes."

  

  If you use a standby cluster application for scalable operation, you must set "AutoStartUp" to "No." Scalable operation controls the startup of a standby cluster application.

• Action to take if another error occurs during failover (double failure)

  Set "HaltFlag" to "Yes."

  

  To ensure safe operation, be sure to set this item to "Yes."

• For Standby operation

  To monitor the resource state of the standby node, set "StandbyTransitions" to "ClearFaultRequest|StartUp|SwitchRequest."

  

  If GLS (Redundant Line Control Function) is used, please make sure to set "ClearFaultRequest|StartUp|SwitchRequest" for "StandbyTransitions" so that the Gls resources on a Standby node can be monitored.

For details on attribute, see "Attributes."

[Set up attribute]

After completing the set up, click Next to go to the "Select Resource" screen.

Selecting resources

Enter the resources to be used by the cluster application.

[Select Resource]

Available Resource

The names of the resources that can be shared among the selected SysNodes are displayed. An available resource is one that was created with the same name in all the SysNodes that are specified by the cluster application.

You cannot share one resource with multiple userApplication. The resource that is used for other userApplication is not displayed.

Selected Resource

The resources to be registered to the cluster application are displayed.

From Available Resource, select the resources to be used by the cluster application, and then click Add. To add all listed resources, click Add all. To remove a resource, select the resource to be removed from Selected Resource, and then click Remove. To remove all listed resources, click Remove all.

After completing the setup, click Next to go to the "Confirm registration" screen.

Checking the registration information of a cluster application

Check the registration information of the cluster application.

[Confirm registration]

Patrol diagnosis facility checkbox

Select this checkbox to enable the patrol diagnosis facility in the cluster application. See "Setting Up Patrol Diagnosis."

SubApplication button

This button is always inactive.

The attributes displayed here cannot be changed. To change the attributes, you must return to "Setting cluster application attributes."

Check the registration information, and then click Registration.

The patrol diagnosis facility can be used in Standby operation. To enable the patrol diagnosis facility, set "ClearFaultRequest|StartUp|SwitchRequest" to "StandbyTransitions" of the cluster application.

For details on attributes, see "Attributes."
