Basic Transformer in Parallel job

Did you create a "parallel routine" (an interlude to your function) in the Repository?

The C program is compiled with +z option.A parallel routine is also present in repository. Do I need to use any function inside the C program or only using main() is sufficient.

A parallel routine (a C function) does NOT have a main() entrypoint.

If I am correct you mean main() is not required and separate function name is required in C.

Yes. You are correct. Its just a function. You can have a main and do the testing from command line, but once all the testing is done, you need to remove the main() function. Also make sure that no input arguments of the C function are defined as const. It does not work with datastage.

I have made the changes in C program without main() funtion. Still I am getting the below error during compilation in transformer:
ld: Can't find library or mismatched ABI for -lorchhpia64

The server is HP-UX.

I am now able to compile and link the job with the following options:
aCC +DD64 -O -c -ext -z +Z test.c
aCC +DD64 -b -Wl,+s -Wl,+vnocompatwarnings test.o

But in the C program I am using file funtions of C like fgets(),fopen() etc. In the C function I am passing char* as an argument. In unix side the program is working fine and giving a correct return value but in datastage it is always giving -1 as return value.

Are the file funtions not recognized by datastage or I need to change something.Please help me with this.

WHile setting up the parallel routine via DataStage, what 'Type' did you provide as the input variables? It should be defined as char*.
But now that i re-read your question, you are saying that its 'return' value is getting messed up, the return value will depend upon your input. Maybe your not handling that input, it could be null. fget(), fopen() are standard commands for the stdio library which you include in your program. That should/will not make a difference.

I am able to run my C program after changing the file name in the program with the full path. I was not using this forum for a while and I am back now.Thanks to all of you.
