Ok guys I am hoping someone can help me out here. I have a 4 proc server with 12GB of RAM. Windows can see all 12 GB of RAM, but DataStage will only use 2GB. I wrote an application that just takes up memory in 2GB sections to test and make sure that the memory could be written to and it can as long as i open multiple instances of the application. DataStage is a 32 bit app so that means that it can only use up to 4 GB of RAM (2 of which is reserved for the OS) The problem is that I am trying to run multiple jobs at once and 2GB of RAM is just not enough. How do i get data stage to take advantage of the rest of the unused RAM in the system? Do i need to start multiple instances and run my jobs in different instances of DS on the same box? thanks for you help!

Welcome aboard. :D

Why do you assert that DataStage will only use 2GB of memory? How did you measure this? DataStage, running multiple jobs, will run multiple processes - did you count the memory consumption of all the uvsh or dssh processes, all the dsapi_server and dsapi_slave processes?
