After we have configured our jobs to run on multiple processors (parallel processing) we frequently get the following messages in the log.comdll0200 file:

Error 11 says that another process cannot be created. How can we solve this issue?

From the programmer's manual the error code means:

11 EAGAIN - No more processes
Description:
This error can indicate that:
The system tries to create another process, but there are no more processes available in the process table.
the user is not allowed to create new processes

Solution:
Increase the NPROCS kernel parameter to allow more processes.

Ok. These information are familiar for me - but where can we exactly raise the number of processes?

It is a Kernel parameter, you would have to check with your Solaris Unix Administrator.
