For completeness, I will mention a couple of easy ways to count using
a SLIP IF on the entry point of the exit routine.
1. ID=xxxx,ML=65535
Then use D SLIP=xxxx to see the number of matches.
2. Use the A=AEXIT,AEXIT=IEAVTSZE as documented under the SLIP command for ZAD
traps.
While this was designed and documented for use with ZAD, it can be useful
for counting any type of PER SLIP trap
(ZAD,IF,SA,SBT,SK).

Thanks you guys. Pretty interesting and technical options were exposed.
However, in this particular case (ICHPWX01 - RACF New-password Exit), it is not
worth the effort. I just want to know how heavily executed it is. Given the
fact that it is invoked just for the following 3 events:
-RACF ALTUSER command (with PASSWORD keyword).-RACF PASSWORD command (with
PASSWORD or INTERVAL keyword).-RACINIT REQUEST=VERIFY (with NEW Password
specified).
I can have an estimation of ICHPWX01 executions by just counting these 3 events
that cause it to be called. And these events generate SMF type 80 records, so I
can go that way.
Thanks,
Juan Mautalen

Are you talking about the EXIT macro? You might be able to use a SLIP trap to

Or use Add Immediate (ASI/AGSI) instead, which is interlocked unless you have
quite an old machine and probably performs better than CDS.
But even if you do have a machine without the interlock, it's unlikely your
update will actually clash, and even if it does your count will probably be off
by only 1. Would it matter? You're not adding to the balance in a bank account.
