User Exit Reference

User Exit Reference

Use the CA VM:Tape user exits to customize the processing for volume security validation and authorization, tape label processing, foreign tape handling (for those tapes not in the TMC), and accounting. User exits also provide the ability to execute a data security erase. User exits are loaded dynamically and therefore do not require that a new VMTAPE MODULE be created. CA VM:Tape now runs in 31-bit addressing mode. ASSEMBLER user exits will need to be changed to be 31-bit safe , because PLISTs being passed to the exits can now be above the 16-M line. MACROs like LINEDIT are no longer safe to use. CA VM:Tape does not support the use of IUCV within user exits.

CA VM:Tape provides prototypes of all the user exits on the CA VM:Tape product LOCALSAM disk. For more information about the location of the LOCALSAM disk media, see the CA Mainframe VM Product Manager Reference Guide. Review the prototypes for ways that you can modify the parameters to fit your processing requirements. Each user exit is described in this chapter.
