the server crashed actually , paging space went up to 25GB but we allotted only 16GB which should be high

Clearly not. You created more processes than this amount of paging space could deal with. Try to create fewer simultaneous processes.

Hi Ray
thanks for the answers - actually the datastage is also installed on citrix and 26 users acccess it parallelly the server thru citrix, as we have only 4 client pc's.
do you think this is one of the reason for paging space issue

thanks

Please clarify: Which server crashed, the server housing the Engine Tier (which processes your jobs) or the Citrix server containing the Client software?

The number of connected users will affect WebSphere Application Server more than DataStage itself. WAS doesn't care whether or not the users are all on a Citrix Server. Of more importance for WAS is the total number of sessions...each instance of any of the client software, or one of the Web tools, creates a separate connection (user session).

How many jobs are you running at one time, especially with 4-way parallelism? 8G of RAM is at the low end of the specifications (minimum is 6GB). As Ray suggests, reduce the total number of processes as you are likely over-committing what little memory you have on the server. Do this by reducing the number of simultaneous jobs and/or the degree of parallelism of your jobs. I'm sure that not all of the NEED to run 4-way.
