Trying to Pass parameter through job control

[sumeet]

Hi,

I am trying to pass a parameter to the job through Job control.

But its not taking the parameter.

Code: Select all

ErrorCode = 0
     ParamName = 'PHID'

    * ParamValue = PH02


      JobHandle = DSJ.ME
      JobName = DSGetJobInfo(JobHandle,DSJ.JOBNAME)

      ErrCode = DSSetParam (JobHandle,ParamName, PH02)

      Call DSLogInfo('SetParam ErrCode = ': ErrCode, 'Msg')


ErrorExit:
     ErrorCode=1
     Return
NormalExit:
     ErrorCode=0

[/code]

The messege I get in the log is:

Test7Job..JobControl (Msg): SetParam ErrCode = -1

What is wrong here???

Thanks
Sumeet

The space between the function name and its left parenthesis is probably the culprit here.

Code: Select all

ErrCode = DSSetParam (JobHandle,ParamName, PH02) 

Error code -1 decodes as "invalid handle".

Ray,

I thought so but , still its not picking the param, even when I remove the space.

SHould I try doing it from a Before sub routine.

Thanks

You're not trying to set a parameter in the same job that's running?!!

Oh gosh, you are!!! (Notes use of DSJ.ME as job handle)

This is specifically prohibited. It's not possible. Job parameter values are set when the job starts, and cannot be changed thereafter.

Thanks Ray for letting me know.

I had the same idea but the manual misguided me a bit.

Code: Select all

JobHandle is the handle for the job as derived from DSAttachJob, or it
may be DSJ.ME to refer to the current job.

So I am going for Before Job Subroutine.

Thanks

It still won't work. "Before-job" is a misnomer; "before-rows" would be a better name. The job is already running when the before-job subroutine is executed.

You can only set parameter values externally. For example in a job sequence. There you can do so from user variables, the result of a routine, the result of a command, to name a few.
