Reclaiming the optical index database

 

A system-level index, called the optical index database, keeps track of all optical volumes and directories known to the system.

The optical index database includes the optical volume index (QAMOVAR) and the optical directory index (QAMOPVR) physical files. You can use the Reclaim Optical (RCLOPT) command to recreate the optical index database if it is ever damaged or destroyed or whenever volumes that you know are in an optical media library, CD-ROM, or DVD device are reported as not found. To run the RCLOPT command, either select option 2 (Reclaim optical index) on the Optical Backup/Recovery display or enter the RCLOPT command. Doing either causes the Reclaim Optical (RCLOPT) display to appear.

The RCLOPT command (shipped with a public authority of *EXCLUDE) applies to directly attached optical media libraries, CD-ROM, and DVD optical devices. You cannot issue the RCLOPT command to LAN-attached optical media libraries. To recreate the Optical Index Database for LAN-attached optical media libraries, use the Add Optical Server (ADDOPTSVR) command.

• Reclaiming the optical index for a stand-alone optical device
  The optical index database recreates entries for CD-ROM and DVD devices each time the device is varied on with media in the device.
• Reclaiming types
  There are three possible types to select: *SYNC, *UPDATE, and *RESET.
• Optical index information
  Optical index information regarding which volumes are in a particular optical media library and which directories are on each volume is kept at different levels within the system.
• Choosing the reclaim type to use
  This topic provides information about choosing which reclaim type to use and when the different options should be used.
