| I have a scenario, some one ran a JCL and which invoked a pgm PXXXX. Now i need to pick up who(Host Id) ran the JCL inside the pgm and display it(or do the processing with it). Is there any register or something like that i can look up to find that out. I know a way using Parm but I am trying to automate this a bit. Let me know if you have any idea on this. Thanks! |

| If the job card has USER= then you will not be able to tell who submitted the job. |

by processing SMF data You can extract all the info needed to determine the userid used to run a <process>

If i don't code USER in the Jobcard, I think RACF assigns automatically the id of user who's submitting it..Right?
How do i read it in the module? |

I've got some REXX code snippets that obtain various values from the Control Blocks. Maybe one or two might be useful?
| Code: |
/*REXX*/
NUMERIC DIGITS(32)
TCB=STORAGE(D2X(540),4)
JSCB=STORAGE(D2X(C2D(TCB)+180),4)
SYSJESN=STORAGE(D2X(C2D(STORAGE(D2X(C2D(JSCB)+316),4))+12),8)
JCT=STORAGE(D2X(C2D(JSCB)+260),4)
SYSJOBN=STORAGE(D2X(C2D(JCT)+24),8)
ACT=STORAGE(D2X(C2D(JCT)+56),3)
SYSPGMR=STORAGE(D2X(C2D(ACT)+24),20)
ACTL=C2D(STORAGE(D2X(C2D(ACT)+48),1))
SYSACCT=STORAGE(D2X(C2D(ACT)+49),ACTL)
SAY WORD(SYSJOBN,1)'('SYSJESN') ACCOUNT('SYSACCT')' SYSPGMR
|
| Code: |
***************************** Top of Data *******
/* REXX */
ASCB = C2D(STORAGE(224,4))
ASSB = C2D(STORAGE(D2X(ASCB+336),4))
JSAB = C2D(STORAGE(D2X(ASSB+168),4))
JBNM = STORAGE(D2X(JSAB+28),8)
JBID = STORAGE(D2X(JSAB+20),8)
USID = STORAGE(D2X(JSAB+44),8)
SAY "JOBNAME="JBNM" JOBID="JBID" USERID="USID
EXIT 0
|
| Code: |
/* Rexx Username */
/* Obtain user name from data areas */
say get_username()
exit
get_username:
ascb = storage(224,4) /* psaaold */
asxb = storage(d2x(c2d(ascb)+108),4) /* ascbasxb */
/* this is USERID(), if you don't need it delete */
asxbuser=strip(storage(d2x(c2d(asxb)+192),8)) /* asxbuser */
/*___RACF___*/
acee=storage(d2x(c2d(asxb)+200),4) /* acee */
/* if you don't need it, delete */
aceegrpn=strip(storage(d2x(c2d(acee)+30),8)) /* aceegrpn */
unam=storage(d2x(c2d(acee)+100),4) /* aceeunam */
user_name=strip(storage(d2x(c2d(unam)+1),24))
return user_name

| The best way is to use the SMF data but it is not available while the job is running. You cannot find this type of data in any register -- you have to load in the address of the TCB, find the address of the JSCB, then the JCT, to find the user id field.at offset 160. Consult your copy of the MVS Data Areas manuals for the appropriate offsets and so forth. |
