14 Create a cartridge entry installation exit routine—CBRUXENT.

If all cartridges entered into the library have the same use attribute and the same tape device selection information (TDSI), these values can be assigned using the entry default use attribute and the entry default data class on the library definition.

If cartridges are to have different use attributes, TDSI, or both, you need to write a cartridge entry installation exit routine. You may use SYS1.SAMPLIB member CBRSPUXE as a model. Otherwise, the system uses the installation exit provided with DFSMSrmm. For detailed information on the installation exit, see Cartridge entry installation exit (CBRUXENT).

 15 Create a change use attribute installation exit routine—CBRUXCUA.

If you need to influence the process of changing a volume’s use attribute (for example, by preventing the return of a private volume to scratch), you need to create an installation exit routine of your own. You may use SYS1.SAMPLIB member CBRSPLCS as a model. Otherwise, the system uses the installation exit provided with DFSMSrmm. For detailed information on the installation exit, see Change use attribute installation exit (CBRUXCUA).

 16 Create a cartridge eject installation exit routine—CBRUXEJC.

If you want to be able to prevent the ejection of a cartridge from the library or to change the tape volume record for an ejected cartridge, you need to create an installation exit of your own. You may use SYS1.SAMPLIB member CBRSPUXJ as a model. Otherwise, the system uses the installation exit provided with DFSMSrmm. For detailed information on the installation exit, see Cartridge eject installation exit (CBRUXEJC).

 17 Create a volume not in library installation exit routine—CBRUXVNL.

If you want to be able to insert a volume into a tape library during job set up, device allocation, or library mount processing to prevent job failures, you need to create an installation exit routine of your own. You may use SYS1.SAMPLIB member CBRSPUXV as a working model. Otherwise, the system uses the installation exit provided with DFSMSrmm. For detailed information on the installation exit, see Volume not in library installation exit (CBRUXVNL).
