7.4.2 Releasing the SSO cluster system environment (in Windows)

This subsection describes how to release the SSO cluster system environment on the active and standby nodes in Windows.

Organization of this subsection

(1) Releasing the cluster system environment on the active node

The procedure for releasing the cluster system environment on the active node consists of the following steps:

  1. Delete the database

  2. Deactivate the SSO resource

  3. Delete SSO from the resource group

  4. Delete the cluster control script

  5. Undo SSO cluster setup

Each step of the above procedure is described below.

(a) Delete the database

Execute the following command to delete the database:

ssodbdel -all

(b) Deactivate the SSO resource

If the SSO resource is operating, deactivate it. To deactivate the SSO resource, place it offline.

(c) Delete SSO from the resource group

In the cluster administrator window, delete the SSO resource from the resource group.

(d) Delete the cluster control script

Delete the cluster control script that was created when the environment was configured.

However, when reconfiguring the environment to change the logical host name in the basic configuration, you do not need to delete the cluster control script.

(e) Undo SSO cluster setup

When you change the SSO operating environment of the active node from the logical host to the physical host, or when you rename the logical host, you need to reconfigure the cluster. In this case, you can inherit the previous settings by undoing SSO cluster setup on the active node.

To undo SSO cluster setup, execute the cluster environment setting command (ssoclustersetup.vbs). For details about the cluster environment setting command, see ssoclustersetup.vbs (Windows only) in 5. Commands.

For the arguments of the cluster environment setting command, specify values as shown in the following table:

Argument

Value to be specified

First argument

-release (specifies that unsetup is to be performed)

Second argument

-primary (specifies that the active node is the target)

Third argument

Shared folder name on the shared disk

Example: K:\shared\SSO

The following shows an example of the command that undoes SSO cluster setup:

cscript.exe $SSO_BIN\ssoclustersetup.vbs -release -primary K:\shared\SSO

If an error occurs, correct it with reference to the message that appears. After you have corrected the error, re-execute the command.

(2) Releasing the cluster system environment on the standby node

The procedure for releasing the cluster system environment on the standby node consists of the following steps:

  1. Delete the cluster control script

  2. Undo SSO cluster setup

Each step of the above procedure is described below.

(a) Delete the cluster control script

Delete the cluster control script that was created when the environment was configured.

However, when reconfiguring the environment to change the logical host name in the basic configuration, you do not need to delete the cluster control script.

(b) Undo SSO cluster setup

When you change the SSO operating environment of the standby node from the logical host to the physical host, you need to reconfigure the cluster. In this case, you can inherit the previous settings by undoing SSO cluster setup on the standby node.

To undo SSO cluster setup:

  1. Mount the shared disk.

    To mount the shared disk to the standby node, select the resource group in the cluster administrator window, and then perform Move Group.

  2. Undo SSO cluster setup.

    Execute the cluster environment setting command (ssoclustersetup.vbs) to undo SSO cluster setup. For details about the cluster environment setting command, see ssoclustersetup.vbs (Windows only) in 5. Commands.

    For the arguments of the cluster environment setting command, specify values as shown in the following table:

    Argument

    Value to be specified

    First argument

    -release (specifies that unsetup is to be performed)

    Second argument

    -secondary (specifies that the standby node is the target)

    Third argument

    Shared folder name on the shared disk

    Example: K:\shared\SSO

    The following shows an example of the command that undoes SSO cluster setup:

    cscript.exe $SSO_BIN\ssoclustersetup.vbs -release -secondary K:\shared\SSO

    If an error occurs, correct it with reference to the message that appears. After you have corrected the error, re-execute the command.

  3. Unmount the shared disk.

    To mount the shared disk to the active node, select the resource group in the cluster administrator window, and then perform Move Group.

(3) Delete the SSO shared data

After you have undone SSO cluster setup on the active and standby nodes, delete the SSO shared data folder (K:\shared\SSO) that was created on the shared disk when the environment was configured (from the active node).

(4) Delete the resource group (in the distributed configuration only)

On the active and standby nodes, if the resource group created by a user for SSO includes other JP1 resources (such as JP1/Base), delete the JP1 resources. Then, delete the resource group created by a user for SSO.
