Resource manager interface program exits XRMIIN and XRMIOUT
Exit XRMIIN
When invoked
Before a task-related user exit program is invoked due to an application
program issuing an RMI API request.
Exit-specific parameters
UEPTRUEN
Address of the name of the task-related user exit program.
UEPTRUEP
Address of the parameter list to be passed to the task-related user
exit program. See note.
UEPRECUR
Address of a halfword recursion counter. The counter is set to 0
when the exit is first invoked, and is incremented for each recursive
call.
Note: The task-related user exit program’s parameter list is mapped by a
DFHUEPAR DSECT that shares common field names with the global
user exit program’s DFHUEPAR parameter list. To include both
DSECT definitions in your exit program, you must code:
DFHUEXIT TYPE=EP,ID=XRMIIN
DFHUEXIT TYPE,TYPE=RM
The statements must be coded in this order.
The two DFHUEPAR parameter lists, the global user exit’s and the
task-related user exit’s, occupy separate areas of storage. The
task-related user exit’s parameter list is provided for information only;
you should not amend it in any way.
Return codes
UERCNORM
Continue processing.
UERCPURG
Task purged during XPI call.
XPI calls
All can be used.
API and SPI commands
All can be used. However, CALLDLI, EXEC DLI, or EXEC SQL commands
must not be used.
