Parallel routine to call DSGetJobInfo

[platonfi]

I try to figure out how to use DSGetJobInfo in Parallel C++ routine, but coud not find any examples. I have following Server routine which I try to translate into Parallel routine. It simply returns USERSTATUS of the job.

Code: Select all

$INCLUDE DSINCLUDE JOBCONTROL.H 
$INCLUDE DSINCLUDE DSJ_XFUNCS.H 
ErrorCode = 0
JobHandle = DSJ.ME 
Ans = DSGetJobInfo(JobHandle,DSJ.USERSTATUS)

My best guess for the same in Parallel C++ routine is following:

Code: Select all

#include <stdlib.h> 
#include <stdio.h> 
#include "C:\IBM\InformationServer\Server\Dsdk\Include\dsapi.h" 

int GetUserStatus(char *RetUserStatus) 
{ 
return GetJobInfo(DSJ.ME, DSJ_USERSTATUS, RetUserStatus); 
}

I know that DSJ.ME is availabe in DS BASIC, but what would be corresponding in C++ DSAPI?

How about returning USERSTATUS value. Could it work like I wrote it? Anything else that might be wrong?

Parallel Job Advanced Developer's Guide (version page 801. There is no mention of an explicit equivalent of DSJ.ME because, in the C API, you have to declare the appropriate structure before you call DSOpenJob().

Thanks for your reply.

The problem is that DSOpenJob requires Jobname as parameter. How can you refer the job where the routine is called from? You just can't hardcode jobname in your routine, neither parametrising the name is a convenient solution. It would require the routine calls to be changed by a job designer in case of renaming a job.

Are there any complete parallel routine code examples using DataStage C API functions available somewhere?
