Outline

AUTORECOVER

If the flag is set to "Yes," RMS attempts to restore the faulted resource for a given amount of time to prevent userApplication being switched to the other host. The default timeout is 60 seconds. You can change it by tuning the resource attribute Timeout. If the faulted resource does not recover within a specified time, userApplication is moved to the other host. If the flag is set to "No", RMS switches userApplication to the other host on detecting the faulted resource.

Checking registration information for Gls resources

Check the registration information for the Gls resources. You can also set resource attributes by selecting the Attributes tab and switching the screen.

For information on the resource attributes, see "Attributes."

Gls resource names are displayed as GlsX (X is a number, such as 0 or 1).

To register a Gls resource to a cluster application, select this resource name from Available Resources on the Select Resource screen.

For details, see "Creating Cluster Applications."

After registering the Gls resources to the cluster application, be sure to restart the system.

Then start RMS, look at the RMS tree, and check that the Gls resources are displayed correctly. For details, see "RMS Tree."

[Confirmation of registration information]

SubApplication button

Use this button to associate a previously created Gls resource under the current Gls resource. This button can be selected only if there are resources of the same type that can be associated. For setting instructions, see "Resource association" in "Creating Cmdline Resources."
