configuration file

Hi,

I would like to get help regarding node configuration.


I know my AIX server has 2 processors. To make use of both the processor's, I created a configuration file like this.

{
node "node1"
{
fastname "datastage"
pools ""
resource disk "/usr/IBM/InformationServer/Server/Datasets" {pools ""}
resource scratchdisk "/usr/IBM/InformationServer/Server/Scratch" {pools ""}
}
node "node2"
{
fastname "datastage"
pools ""
resource disk "/usr/IBM/InformationServer/Server/Datasets" {pools ""}
resource scratchdisk "/usr/IBM/InformationServer/Server/Scratch" {pools ""}
}

}


Is that the only thing I need to do to make use of both the processors? To be honest, seeing the speed of jobs, I don't feel I am not using both the processors. Please help is there anything else I need to do other than just creating the configuration file to make use of both the nodes.

Many thanks in advance.



Just an additional information. I ran a "check" of this configuration file from DEsigner > Tools > Configuration file but saw 5632MB for node1 and nothing has mentioned about node2. so is my confusion.

First thing to understand is that while "processor" is a physical concept, an actual discrete piece of hardware in your system, a "node" is nothing more than a logical concept and has no direct relationship with CPUs. Its just another process that your server needs to run and your O/S decides what CPU it runs on - meaning that, even if you had 4 nodes defined in your config, they would all happily run on one CPU and may even do so in spite of you having two. It's all up to the operating system.
