When trying to resolve a certificate problem in a Java program, see here, I tried unsuccessfully to take a RACF trace to see what calls were being issued, and what reason codes were being returned.
The RACF GTF had no entries for the Java program!
Start RACF trace
My started task was called OZUSRV4. I had to specify a jobname to RACF trace of OZUSRV4* because Java spawns address spaces, and it was a spawned address space that did all of the Java work. If your started task is 8 characters long – just specify the 8 character name.
The trace command was the RACF SET TRACE command, where # is my RACF subsystem recognition character.
#SET TRACE(CALLABLE(TYPE(41))JOBNAME(OZUSVR4*))
Where type(41) is for IRRSDL00 which performs the R_datalib, keyring processing.
Start GTF
S GTF.GTF R 1,trace=usrp R 2,USR=(F44) R 3,END R 4,U
Run the test
I ran my started task, and stopped the RACF trace
#SET TRACE(CALLABLE(NONE))JOBNAME(OZUSVR4*)) #set list
The output of the #set list command included
TRACE OPTIONS - NOIMAGE
- NOAPPC
- NOSYSTEMSSL
- NORRSF
- NORACROUTE
- NOCALLABLE
- NOPDCALLABLE
- NODATABASE
- NOGENERICANCHOR
- NOASID
- JOBNAME
OZUSVR4*
- NOCLASS
- NOUSERID
SUBSYSTEM USERID - START1
So the traces are off…. but it still has a reference to OZUSVR4 – strange.
Process the GTF file.
I used IPCS to look at the GTF file
- =0 and specify the GTF file name
- =6 dropd to drop any saved status from last time that dataset was used
- gtf usr(all) It displays the output in an editor like window.
- report view displays it in ISPF editor, view mod.
- You can the do things like
- x all
- f ‘RACF Reason code’ all
To display the records with non zero return codes.
The output is very chatty – and it was hard to find the data I wanted from data with a hex dump of the string “OFFSET” etc. For example

I wrote a REXX exec which post processes the output and removes what I think is irrelevant data.
An example of what I think is useful is below. Non zero return codes have ! in column 1
! Return code: 00000008 8 ! Reason code: 00000004 4 4 Parameter list error occurred. - - - - - - - - - - - - - - - - - - - - - - - - - - - ! Return code: 00000008 8 !

You can download the rexx exec from
You need to upload it to a CLIST available to ISPF.
