I need to monitor a JCL that I'm submitting thru my REXX code, and make my further REXX code wait and execute only after successful completion of this JCL.
Can someone pls help ! |

| I'm thinking that a combination of the TSO "STATUS" and "OUTPUT" commands ought to work. |

And search for how to use the USS sleep command. You don't want to just sit in a tight loop looking at the queues.
It is also possible to see what is running in the system by chasing control blocks, but finding the job number is not easy so if there is a possibility of multiple (Sequential) jobs running with the same name, you'll need to search for the job number as well as the name per Kevin's suggestion. |

| actually, you have to use Status because you can't tell by looking at control blocks if the job is still waiting to start. |

| In some cases another option is run the job in foreground...of course it depends on number of steps, how long it's gonna take... but it's just another option. |

You should catch the job name and job number by using x = OUTTRAP('trap.') before the SUBMIT command and x = OUTTRAP('OFF) after it. The stem variable "trap." will contain all lines written to your terminal, thus the line "IKJ56250I JOB USERIDX(JOB49616) SUBMITTED". After that you should code a loop using "address syscall 'sleep' 1;x=OUTTRAP('trap.');address tso 'status' jobname;x=OUTTRAP('OFF')". These lines cause your program to wait for 1 second and query the status of all jobs with the specified jobname. The output will be written once again to your terminal and thus trapped by the OUTTRAP function into the stem variable trap.
But although it seems quite easy to get this information, I think it is poor design to loop in an online application to wait for the result of a asynchronously running batch task. I would always prefer a solution as acevedo has outlined. |

Hi stefan,
I tried that 'STATUS' option. But it will give only the info whether the job is over or not. From that we won't get any thing like whether it was successful or not. We will get the return code from 'OUTPUT' option. But i was not able to trap that one. Is there any solution for this? |

I setup a quick feasability test:
| Code: |
/* REXX */
Queue "//SUPERK# JOB (.....),'',CLASS=T,MSGCLASS=X,"
Queue "// MSGLEVEL=(1,1)"
Queue "//*"
Queue "//STEP0001 EXEC PGM=IEFBR14"
Queue "//*"
Queue Left("$$",80)
o = OUTTRAP("output.",,"CONCAT")
"SUBMIT * END($$)" /* Submit JCL */
o = OUTTRAP(Off)
msg = Strip(output.2)
Parse Var msg msgid 'JOB' jobname '(' jobid ')' .
Do Forever
o = OUTTRAP("output.",,"CONCAT")
"STATUS "Strip(jobname)"("Strip(jobid)")"
o = OUTTRAP(Off)
Parse Var output.1 msgid 'JOB' jobname '(' jobid ')' msg
If msg = "ON OUTPUT QUEUE" Then Leave
End
dsname = Strip(jobname)||"."||Strip(jobid)||".OUTLIST"
"OUTPUT "Strip(jobname)"("Strip(jobid)") PRINT("dsname")",
"BEGIN HOLD KEEP"
Exit
|
This gives me a dataset 'userid.JOBNAME.JOB#####.OUTLIST' with all of the runtime statistics. |

My solve is below.
Notes:
1) I've run the rexx from batch;
2) you must have a NETRC dataset in your 'home';
3) FTP server must be running with JESINTERFACELEVEL = 2.
