I am running AIX 5.3 and we run a process during the night that takes several hours to complete. When i monitor this it is only consuming about 50% of CPU power. I have changed the "nice" setting for that process and it does not consume any more power. IS there a way that i can set that process to consume more resources therefore complete quicker.

My guess is you have 2 processors and 1 single threaded process. In that instance, your process is using a full processor, which is 50% of the capacity of the box. However, a single threaded process can't consume more than a full CPU's worth of time.

Let me know if I'm barking up the wrong problem.

I will monitor the resources in the morning and let you know. Thannks for the reply

How many processors are there in the box?

What is the process that is running and only consuming 50% of CPU? Is it by any chance a shell script?

The server has cpu0 through to cpu7, i believe it is 4 physical but they are dual which gives me 8. This morning when it was running the cpu's were at 56,51,65,68 % idle values, this was early in the morning with no one else logged in. It is a shell script that starts two processes in a cisam database.
The processes have a nice value of 32 which is very high but i thought that wouold not have much effect when other users were not logged in.

On a lighter note use Microsoft Windows, you will end up consuming more than 100% cpu for doing nothing !!

Pardon me for the PJ :P

IBM Aix must have a WLM or else you can even try a shot at WPARS if you are running Aix 6.1
