[Configuration by RMS Wizard]

1) Configuration of userApplication: After configuring HOST-A and HOST-B, register the created takeover virtual interface as a Gls resource to create a cluster application. Use RMS Wizard to set up the cluster configuration. For details, see "PRIMECLUSTER Installation and Administration Guide".

2) Starting of userApplication: After completing the configuration, start the userApplication to activate the takeover virtual interface on the operation node.

[GS-1]

Set the information for HOST-A's physical IP address and virtual IP address. For information on how to do this, see the GS manual.
