Hi
Our environment has 4 physical nodes. I changed configuration file to make 6 vertual nodes. The job is aborting saying the following message.
But when I chaged the configuration file from 6 nodes to 4 nodes the job is running successfully with 4 processes.
could any body please suggest me how do I increase the processes from 4 to 6 or more.
thanks

Increasing number of processes

Your operator or System Administrator will need to make configuration changes to allow more concurrent processes available per user id. Each version of UNIX has a different way of doing this, so without knowing what platform you are running on we cannot help directly.

Hi
Our platform is HP-UX B.11.11 U 9000/800. I am changing the configuration file through Datastage manager. I am providing the configuration file name to the job through $APT_CONFIG_FILE. I am expecting the job should take the new configuration file in which there are 6 virtual nodes and should create 6 processes. COuld you explain how the configuration file will change the number of processes and suggest me how do we increase the number of processes.
thanks

Nivas,
these parameters have nothing to do with the APT_CONFIG file; they are system parameters.
The two parameters that affect you in HP-UX are maxuprc (processes per user) and nproc (total processes on system). You cannot change these, they must be modified by a superuser on your system.

Nivas,
increasing the APT_CONFIG from 4 to 6 doesn't meant that now you have 6 processes in total where you only had 4 before; it means that each stage in your job now executes with 6 instead of 4 jobs. So if you have 20 stages in your job this APT_CONFIG change has increased the number of process running for the job by 40. It is not unkown for complex jobs with many nodes to generate over 1000 pids! And if several jobs run at the same time under the same userid the normal limits are very quickly reached.
