When a target computer reports that it has had a new operating system (OS) installation (visible by a change in the HostUUID), all old successful installation and delivery records will be marked with "*Removed by RAC" in the job history of the target computer.
Note: If the configuration policy "DSM/software delivery/Manager/RAC" is set to False, existing records remain untouched and no RAC job container is created.
Then, depending on the current RAC policy configuration setting, a job container will automatically be created or not by a domain manager. All old successful jobs associated with the installation and delivery records previously mentioned are included in the container that will appear in the list of job containers, with its name prefixed by RAC. The name of the job container follows the scheme:
RAC: computer_name [ current_date current_time]
All RAC containers are tagged with the UUID of the actual computer at the time it got the new OS installation. This ensures that only RAC containers with an up-to-date UUID will be performed. Jobs in an RAC container with an old UUID will fail and set in error state: RAC container obsolete. This situation may occur if the software delivery agent is reinstalled with a new operating system, before a previously generated RAC container has finished executing.
New installations and jobs, generated off-line and reported along with the new OS installation (that is, using the new UUID), are not included in the RAC container. Old and new installations for targets are separated, by recording the UUID for each job. All job records generated off-line are tagged with the UUID.
The restriction in previous software delivery versions to prohibit execution of activate and configure procedures, unless bound to an existing installation for the current target, has been weakened to let an RAC container carry out all jobs, based on the job history of the job target, in one attempt.
To regenerate as much as possible of the target, the default values used for an RAC job container are:
Note: Batch linkage can be changed to synchronized for an unsealed job container.
When creating the RAC container, the completion time of the computer jobs (job history) is used to establish the initial order of the jobs. Deliveries are always placed first. As long as the job container is unsealed, jobs can be deleted or repositioned. More jobs can also be added to the container.
If a job cannot be set up, since the software to use is archived, the job is set in warning state and the job container is left unsealed.
Jobs that had not finished executing before RAC was initiated are set in error state. They are not included in the RAC container and cannot be renewed, since they are tagged with the old UUID. After the RAC process has finished, check whether they should be set up again.
When a RAC job container has been created for a target, the target is locked until the container has completed successfully, or has been deleted. While the target is locked, the computer name is displayed in red text in the DSM Explorer tree.
During this time, it is not possible to deliver, execute, or delete any other jobs to the target computer. Any jobs that are set up will fail with the error status: Job is not allowed. Target is locked for RAC.
During the time the target computer is locked, template jobs for the actual target are set up and added to the Exceptions folder. However, when activated they will fail if the lock still remains. Jobs requested from the enterprise manager are set to error, if activated when the target computer is locked. Installation and job records cannot be deleted during the time the target computer is locked.
In situations where an RAC container fails, the standard renew function is accessible. If a job fails because it cannot execute on the new OS installation, that job can be deleted from the RAC container, before it is renewed.
If a complete renew with a new operating system is required, the RAC container should be deleted and a new OS installation be initiated.
If the selected RAC policy states that no RAC automation shall take place or if no jobs were set up, the target computer is unlocked as soon as its installation register has been cleaned up.
