Enabling the exit programs

To enable an exit program you must complete one of two possible actions.

To enable these exits, you must do one of the following:
  • Specify the system initialization parameter TBEXITS=(name1,name2,name3,name4,name5,name6), where name1 through name6 are the names of your user exit programs for XRCINIT, XRCINPT, XFCBFAIL, XFCLDEL, XFCBOVER, and XFCBOUT.
  • Enable the exits during the first stage of initialization using a PLTPI program.

If you use the TBEXITS parameter to enable the exits, a global work area of 4 bytes is provided. If you use a PLTPI program, you can select the size of the global work area. You can also enable more than one exit program for use at each exit point; the TBEXITS parameter allows only one exit program at each exit point. PLTPI processing is described in Writing initialization and shutdown programs.
