log errors:

your job is consuming too memory (RAM).
Optimize it.

You can increase through Datastage Client (Adminstrator).

Yeah?!!

Please elaborate on how you can change an operating system setting through the DataStage Administrator client. Particularly something like ulimit, which requires superuser privileges to increase.

Hi reddy,

How can you change the ulimit value through administrator which is not possible using client?

Check the ulimit first

From unix Prompt type in > ulimit -aH ( for hard allocation limits) and > ulimit -aS (for soft allocation)

1)If they are not set to "unlimited" , ask your UNIX admin to do that.

2) Also frequest him to have sufficient temporary space( Scratch) added.

3) If you are using DB2 API stage there is a memory leak issue and you need to contact support to give you a patch.

I have seen similar issue in ODBC stage as well, but I am not sure of a patch available for it.
