Operations performed after initial provision or after a refresh.
This hook will run after the virtual dataset has been started.
Operations performed before a refresh.
These operations can cache data from the virtual dataset to be restored after the refresh completes.
Operations performed after a refresh.
These operations can restore cached data after the refresh completes.
Operations performed before a rewind.
These operations can cache data from the virtual dataset to be restored after the rewind completes.
Operations performed after a rewind. This hook will not run if the rewind or Pre-Rewind hook operations fail.
These operations can restore cached data after the rewind completes.
Operations performed before a snapshot.
These operations can quiesce data to be captured during the snapshot, or stop processes that may interfere with the snapshot.
Operations performed after a snapshot.
These operations can undo any changes made by the Pre-Snapshot hook.
Operations performed before startup of a VDB or vFile.
These operations can be used to initialize configuration files or stop processes that might interfere with the virtual dataset.
Operations performed after startup of a VDB of vFile.
These operations can be used to clean up any temporary files, or restart processes that may have been stopped by a Pre-Start hook, or log notifications.
Operations performed before shutdown of a VDB or vFile.
These operations can quiesce data or processes prior to virtual dataset shutdown.
Operations performed after shutdown of a VDB or vFile.
You can leverage hooks to run required scripts which address several different use cases. For example, you may want to prevent your monitoring systems from triggering during VDB startup and shutdown.
If a hook operation fails, it will fail the entire hook: no further operations within the failed hook will be run.
