Nodes in configuration file

[tine_bi]

Hi

We are running Datastage(9.1.2) on a windows 2008 R2 server.
the server is a Hyper-V, now setup with 8 CPU and 24 GB memory.
We have three disks, C(100GB),D(500GB),E(50GB)

I am looking at some tech notes about node setup and I am a bit confused. Some say you need half the nodes of #CPU, some say one for each disk, while others say it is a matter of testing.

I have set up the following as a test:

Code: Select all

node "node1"
        {
                fastname "DSSRV01"
                pools ""
                resource disk "C:/IBM_NODE_CONFIG/Datasets" {pools ""}
                resource scratchdisk "C:/IBM_NODE_CONFIG/Scratch" {pools ""}
        }
        node "node2"
        {
                fastname "DSSRV01"
                pools ""
                resource disk "D:/IBM_NODE_CONFIG/Datasets" {pools ""}
                resource scratchdisk "D:/IBM_NODE_CONFIG/Scratch" {pools ""}
        }
		node "node3"
        {
                fastname "DSSRV01"
                pools ""
                resource disk "E:/IBM_NODE_CONFIG/Datasets" {pools ""}
                resource scratchdisk "E:/IBM_NODE_CONFIG/Scratch" {pools ""}
        }

All works just fine, have tested with default two nodes, but cannot see any change.(then again I might be checking things the wrong way)

Also read bout setting nodes with several resource disks like:

{
	node "dev1"
	{
		fastname "etltools-dev"
		pool ""
		resource disk "/data/etltools-tutorial/d1" { }
		resource disk "/data/etltools-tutorial/d2" { }		
		resource scratchdisk "/data/etltools-tutorial/temp" { }
	}

	node "dev2"
	{
		fastname "etltools-dev"
		pool ""
		resource disk "/data/etltools-tutorial/d1" { }
		resource scratchdisk "/data/etltools-tutorial/temp" { }
	}	
}

Is this the better option?

Any comments on best practice?
