Hi Gurus,

I have a complex datastage jobs. I run it on test environment (2-Nodes). Prod Environment(4-Node) and Stage Environment(3-Node).

The job runs fine on Test and Prod but always fails on Stage with a fork() error. (Not enough Space).

I tried running the job in stage environment on 2 and eventually 1 node, Still its failing. I am unable to understand this behaviour....

Below is the output of hte check option on the single node config file

Code: Select all

Forgot to mention this one.

The OS is SUN Solaris

did you try with 2 node configuration file in stage environment?

Posted: **Thu Jul 03, 2008 7:38 am**

Yes, I tried with 2 Node and with single node also.... Also to add environments are isolated.

The job on 3 nodes creates 159 Process.

2 Nodes - 102 and on

1 Node - 55 Process.

Are all 3 environments on the same machine? Solaris is odd in that it preallocates swap space when memory is allocated.

Andrw,

All environments are isolated and lie on different servers.

do you get the same error when you run the job in 2 node configuration file in stage environment

Add extra file systems to resource scratchdisk.

Your problem is related to how Solaris manages it's virtual memory.Please log a call with IBM support and they will sort you out.

As earlier Ray had told,

check where is the location for the scratch space.
it will be mention in the Configuration File.
now check that location lies in which file system and check the free space.

can you check how many cpu are there in your respective server
let say 6 CPU are there then mention 3 node in the Configuration file.

In that case the one machine has less swap space than the others and that is causing your virtual memory issues.
