(MIA) TPCINIT Statement-Set TPCF Exit Routine Order

The TPCINIT Statement determines the POS value specified by TPCF on the z/OS CSVDYNEX macro when TPCF adds its Autoreply exit routines as z/OS Allocation Recovery user exit routines for z/OS user exits IEF_ ALLC_ OFFLN and IEF_ SPEC_ WAIT. The value specified determines where in the list of possible multiple exit routines, z/OS places the TPCF exit routines. The order in which the exit routines are placed on the z/OS list is the order in which they will be called by z/OS.

Scope: N/A

This statement has the following format:

TPCINIT	[AUTOREPLYPOS=FIRST|LAST|SYSTEM]

AUTOREPLYPOS

(Optional) Determines where z/OS places the TCPF exit routines in the list of possible multiple exit routines. Valid values are:

FIRST

Specifies that z/OS should call the TPCF exit routines before any other exit routines, unless other exit routines added after them also specify POS=FIRST.

LAST

Specifies that z/OS should call the TPCF exit routines after any other exit routines, unless other exit routines added after them also specify POS=LAST.

SYSTEM

Specifies that z/OS should call the TPCF exit routines in any order relative to other exit routines.

Default: AUTOREPLYPOS=LAST

Usage Notes: TPCINIT Statement

• You may need to use this parameter when there are multiple z/OS Allocation Recovery exit routines active on the system. In addition to the TPCF exit routines, this would include user-written exit routines and exit routines added by other software products.
• You can determine what z/OS Allocation Recovery exit routines are active on the system, and in what order they will be called, by examining displays generated by the following z/OS operator commands:

  D PROG,EXIT,EXITNAME=IEF_ALLC_OFFLIN
  D PROG,EXIT, EXITNAME=IEF_SPEC_WAIT
  

  In the preceding displays, the CA MIA recovery exit can be identified by the name MIAALOCX.

• The TPCF exits are usually last (TPCINIT AUTOREPLYPOS=LAST) for correct AUTOREPLY and device elimination. However, different placement of the TPCF exits may be required, depending on the other exit routines that are loaded. If you experience problems with AUTOREPLY or device elimination, then use the D PROG displays above to determine what other exits are loaded and check with the appropriate vendor/exit author to determine the order required by the exits.

Examples: TPCINIT Statement

• To specify that z/OS should call the TPCF exit routines after other exit routines, place the following statement in the MIMINIT member:

  TPCINIT AUTOREPLYPOS=LAST
  

• To specify that z/OS should call the TPCF exit routines in any order relative to other exit routines, specify this statement in the initialization member:

  TPCINIT AUTOREPLYPOS=SYSTEM
