RACing ahead with Oracle on VMware - Part 3: Installing Oracle 10g Release 2 Clusterware on a 2-node Windows 2003 Enterprise Edition Server - Page 2

By Tarry Singh

What is this thing with missing/hidden NIC's?

This can be really frustrating, especially with VM's. I often had problems with lost NIC cards and then if I recreated OR tried to assign an IP address to the (strangely) newfound device (NIC card), I got an error of a hidden NIC device having that same IP address! Follow these print screens below to save yourself from such irritation.

Step1: After the error you try to locate that hidden device.

Step 2: Well you don't see it, now do you?

Step 3: Go to the command line and do the following:

Step 4: And then try to find the hidden device.

Step 5: And look what we have here…

Step 6: Get rid of all the hidden NIC's.

Step 7: Make sure to edit your host file for only your private NIC cards (all node entries on all nodes!).

Step 8: Ping all nodes from all machines (including your own node).

Step 8: Make sure the public and private cards have same names across all nodes (just to add on that, also the machine names, DNS entries should reflect the same behavior as well, remember case sensitivity). Clusterware is a very stubborn tool and will not accept any mistakes or errors.

Anyways, I'm assuming that you are all ready to install your Oracle 10g Release 2 clusterware software across the nodes.

Installing Oracle 10g Release 2 Clusterware

Running pre cluvfy tests

The pre tests are primarily to test that your machines are cluster aware.

Step 1: You are all set, so let's run the cluvfy command.

Step 2: Check machine requirements.

Step 3: Check node connectivity.

Step 4: Check Shared Storage Availability across all nodes.

You are done with the checks and it is time to run the installer.
