With the IBM ATL configured in BTLS mode, most functions are performed in batch using IDCAMS with the LIBRARY command. In addition, the CTSBTLS program is linked as IDCLI04, the name of the Set Category Installation Exit.
To ensure that the status is correct on new cartridges being entered into a IBM BTLS ATL, a list of all tapes currently in the INSERT category are processed through the Set Category Installation Exit. The exit determines their current status in the CA 1 TMC, and then sets the cartridges to the correct category (PRIVATE, SCRTCH, or ERROR).
To allow the synchronization between CA 1 and the BTLS database, an inventory of all cartridges currently in the ATL is created. This list is passed through the same exit, which again determines their current status in the tape management system, and then sets the cartridges to the correct category.
To eject tapes and to set tapes to a category of SCRTCH after they have been scratched by the Tape Management System, lists of volumes are used as input to an IDCAMS job. The IDCAMS job then sets the category for all tapes in the list to a specified value (for example XEJECT or SCRTCH for example.)
