VVR enables you to integrate application preparation tasks, IBC messaging, and off-host processing tasks using the single command vradmin ibc. The vradmin ibc command simplifies the off-host processing task by providing scripts for application-specific tasks. The vradmin ibc command uses IBC Messaging and executes a set of user-defined scripts to perform the required off-host processing task. You are not required to remember the sequence in which to perform these tasks. The vradmin ibc command simplifies the off-host processing process by performing the following operations:
Executes application-specific scripts and the scripts to be used for off-host processing in the required sequence.
Executes these scripts on the appropriate host, that is, Primary or the Secondary.
Inserts the IBC message at the appropriate time.
