Explanation

The workflow for refreshing XtremIO Snapshots, containing Oracle Database files, consists of the following five simple steps: 1. Shut down the database instances with files in the target Snapshot Set. 2. Dismount the ASM disk group (or file systems) involved. 3. Refresh the Snapshot via XtremIO GUI (or CLI or RESTful API). 4. Mount the ASM disk groups (or file system) involved. 5. Start the database instances. This entire workflow is measured in seconds (not minutes). Incorrect Answers: A: The refresh command is a powerful tool for test and development environments and for the offline processing use case. With a single command, a snapshot of the production volume or CG is taken and the SCSI face of the volume, which was mapped to the test and development application, is moved to it. This allows the test and development application to work on current data without the need to copy data or to rescan. oracle-databases.pdf, page 8
