DSXchange

so sad I search in the forum so long time but cannot find any post.

I use a routine to run the DS job, now I want to specify the different APT fot different job, eg. file1.apt for job1, file2.apt for job2.

I hope I can set this by DSSETPARM like the user defined params but failed.

paramerr = DSSetParam (job2 , "$APT_CONFIG_FILE", '/sysp/DataStage81/InformationServer/Server/Configurations/file1.apt')

It still uses the default apt to run.

do I use the incorrect function to run?

Did you check 'paramerr' after the function call? What is 'job2'? It needs to be a handle to a job, not an actual job name, obtained using DSAttachJob.

get it.. i will check the paramerr

code=-3 [ParamName does not reference a known parameter of the job]
hi chulett,
this is the error it shows, could u please advise how to fix ?

it's not correct to set environment variable user ds set parm
I found this in the forum.
but I want the job to run for different apt. e.g. the routine starts job1 using apt1, starts job2 using apt2. what should i do ?

Did you actually declare the APT_CONFIG_FILE parameter explicitly in your job?

Yes, it is both possible and you are using the correct function. As noted, you need to declare it as a job parameter in the job (this is one of several that should be in every job) to allow it to be overridden on a run-by-run basis as needed.

I also found this 'remark' in the latest documentation as shown here.

Remarks

The job specified by JobHandle must be locked, using DSLockJob, before the DSSetParam function is called.

That's a new one on me as I don't remember ever having to do that or even seeing that function before.

I believe that the DSLockJob() is when using the c interface, I can't see it mentioned for the BASIC calls documentation (11.3) and it isn't even defined - I get a compile error when I try to use it.

True... sorry, didn't realize I'd stumbled into the C API documentation.

You seem to have missed calls to DSAttachJob() and DSDetachJob().

i called DSAttachJob. And also add system variable in the parallel job.
But failed on set parm , saying no this parm.

Are you 100% certain that you defined this parameter in the job (case sensitive)? Could you also post your DSAttachJob() call?

yes.
define the system parm in the parallel job property;
DSAttachJob to get the parallel job handler;
DSSetParm to set parm to this system parm.

when run job, 'no this parm' error.

btw, i set many parms to the parallel job. others are all okay, the system parm fail

I'm not sure why this is popping into my head but could you try not including the $ in your DSSetParam call?
