What do data formats specify?
Data formats specify how data values are to be displayed, such as what type of numerical or textual representation should be used for a given set of data. This allows the data to be displayed in a way that makes sense to the user and is easily understandable. Data formats also define the structure and organization of the data, allowing it to be read into a container or merged with other data sources.
You have an MPP SAS Viva environment with a primary CAS Controller and a backup CAS Controller. The primary controller fails and your backup controller is now active.
Which task will you need to complete during the process of recovering the primary controller?
When recovering a primary controller, you need to restore the permstore from the backup controller to the primary controller. The permstore contains the state of the CAS session and other important information related to the CAS environment, such as configuration, metadata, and user data. Restoring the permstore from the backup controller allows the primary controller to resume operation with minimal data loss.
The process of restoring the permstore from the backup controller to the primary controller can be done by using the sas-admin permstore-restore command.
It is important to note that, before restoring the permstore, you should stop SAS services on all the CAS workers, in order to avoid data corruption during the restore process. Also, it is not recommended to delete the permstore from the backup controller, as it is useful in case of primary controller failure. CASDISKCACHE is used for caching purpose, it's not related to permstore or primary controller failure.
