Hi Gurus,
I am new to UNIX environment. We have our DataStage tool installed on UNIX box.We have Dev,test and Prod environments.The architecrue is as given below.
Now my problem is I am not able to know what is meant by Physical name,Logical name,Cluster etc. also we need to do failover in case a node changes.What is a node here in this architecture.Please help me out.

Dev Logical name Dev01

  1. Cluster Name - No name
  2. Physical names -Dev02

test Logical name:test01

  1. Cluster Name - C09
  2. Physical names -test02,test03,test04,test05

prod Logical name:Prod01

  1. Cluster Name - C08
  2. Physical names -prod02,prod03,prod04,prod05,prod06

You should register on the dsxchange forum if you are using DataStage.

Thanks for replying..I know that Dsxchange is the forum for DataStage.But since the OS is UNIX I have posted this question here

You are not helping us much - not saying what OS...
So let explain what can be, for any unix box:
The physical name is the host name, the one running the OS, but depending of the OS if you are a VPAR this is no more true...
If I describe what I know best: HP-UX, in a simple cluster (MX-serviceGuard soft) version with no VPAR, you would have for a cluster :
2 nodes -> 2 boxes (2 hosts...)
1 or more packages running on the cluster, these packages have "logical names" because the have their own IP and can be pingged...
A package has a default host on which it runs...
So if I summarize:
In a 2 node cluster my package runs on node1, if a failure should occur, it will be restarted on node2...

Of any help?

Sure, but the post didn't specify this was just about UNIX.

I recommend searching google for each of the terms, such as cluster.

I was stating that if you have a DataStage implementation question that is specific, I would recommend Dsxchange.
