If the RAC Policy is selected, when a new operating system has been installed, the software delivery (SD) agent notifies the domain manager. The domain manager sets the state of the computer to Reinstall After Crash and locks the computer. All installation records in the Jobs folder for the SD agent are marked as uninstalled.
The domain manager does one of the following:
Takes no further action, except unlocking the computer again (disabled RAC automation).
Creates an RAC job container for the SD agent, fills the container with orders to execute all previously successfully executed jobs and leaves the container unsealed (deferred RAC automation). The container can be reviewed and modified, since it has to be activated manually.
Creates an RAC job container for the SD agent, fills it with orders to execute all jobs that were previously successfully executed, seals and activates the job container (automatic RAC automation).
If a Windows computer has user profile agents, the computer profile and each user profile agent will be handled separately. Each SD agent will have its installation records deleted separately and get its own job container, if any are to be generated.
The default configuration policy parameters is set to True for RAC, which means whenever a new OS is installed on an agent it initiates the RAC Jobs.
You should be able to release the RAC lock on all machines by running the following SQL query:
update dbo.usd_v_target set locks = 0
Note: You should not use the above command IF there are machines which are in a valid RAC state as it will reset the lock on those also.
