DataStage Server performance very slow on vmware
DataStage 8.1 is installed on Windows 2003 server on vmware with 16 GB Ram and 4 Cpu's.Even after such a good resources the DataStage server is very slow and websphere is occupying almost 13 GB out of 16 GB even though none of the job is being ran.The jobs are very slow and if two users try to connect it hangs.Any suggestions of how to overcome this,how to improve the performance and how to find the memory leaks exactly.Any patches to install which will fix this.we already installed fp1 and fp3.

Add more virtual memory (lots more- at least 4GB to the server, 8GB preferred, and at least 2GB to the client) to the VMWare images. If the underlying machine does not support that, get a higher-powered (more memory) underlying machine.

I am having 8.1 installed on VMWARE player. My server has got just 6 GB RAM. But it does well. Like ray suggested, my advice is also to increase the virtual memory size. It should do well.
My configuration is
Windows 2003 Server Enterprise
VMWARE player
8 GB RAM , VMWARE allocation is 6 GB
Virtual memory allocated to Windows server is close to 6 GB
Additionally do a watch of DB2 memory consumption, if your metadata repository is on the same server box. DB2 DBA can help in that case. A good performance tuning of DB2 also might help.
