hi
i need to run a script that will process the seq file which will be used in another job.
if i run the script from unix i think it runs on single node but if i can call the script in a datastage stage i think it will run on multiple nodes

please advise on this

and why do you think so???

it will run on head node only

You could check out the possibility of using a wrapped stage... but automatically assuming that a unix script designed to operate on a sequential file will run fine in parallel is naive.

What is your main purpose..?
to run the unix script to get the sequential file processing to next job ..

rite ??

or u r trying to test the funtionality of how unix script is executed when used in the DS jobs..

When unix script is called from unix job, unix excutes it and it does not run in parallel.. ! this is what u r thinking u guess !

in DS job u can use script in before and after job routine depending on your requirement..!

hope this helps
