How do I dynamically replace my IEFACTRT exit without IPLing?
Here is an example of dynamically replacing a IEFACTRT routine named XYZACTRT with the IBM SETPROG commands: SETPROG EXIT,DELETE,EXITNAME=SYS.IEFACTRT,MODNAME=XYZACTRT SETPROG EXIT,ADD,EXITNAME=SYS.IEFACTRT,MODNAME=XYZACTRT,DSNAME=SYS2.XYZ.LINKLIB Where you issued the command for SYS.IEFACTRT, you may need to also do SYSJES2.IEFACTRT, SYSTSU.IEFACTRT and/or SYSSTC.IEFACTRT (if the IEFACTRT exit was originally defined that way via the SETPROG or PROGxx member).
