Clustering help needed

[Jessica P]

Hi

I hav configured clustering on 2 HP UX nodes.Initially the server had OS and i configured clustering.Now the nodes are shown as up in cluster..Do i need to install the application(ORACLE) first before i configure the package part...or i can go ahead with package configuration now and install application later on ...plz suggest

thanks

I think for best way is : Create your oracle package only filesystem and your IP package.

it is more esier for you. No need changes regarding IP changes from phisical IP to IP package


Thanks

You need to install oracle first and then configure the package as you need to configure the services which will be running as part of the package in the package control file.

Install oracle, configure it, and get it up and running. Then convert that into a package.

When configuring oracle keep in mind that you are clustering it. So plumb the package IP, so you can completely test oracle is working before packaging it.

i think both of that method its ok. but when you configure without ip apckage, you will do some changes for configure package example your listener, and the others. To risky for me to changes from oracle site.


thanks

Hello,

We just got down configuring MCSG. I think it is better to have the application in stalled. You can set up your pkg with IP and try switch the pkg around between nodes. Then just add your application to the pkg.

Installing the application on one node and then moving it into the cluster form had yielded better results for us, but to each hisor her own.

But if you are taking our approach, I'd strongly suggest you to halt the cluster first, which will release the relocatable IP address, then assign this IP address to the primary interface of your server where you are going to install oracle as a sub interface.

Example:
server1 :10.21.33.2 (lan1)
server2 :10.21.33.3 (lan1)
relocatible IP : 10.21.33.10

Assuming you are going to install oracle on server1

server1# cmhaltcl
server1# ifconfig lan1:1 inet 10.21.33.10 netmask 255.255.255.0 up
(install oracle with the server name resolving to 10.21.33.10 on server1)
server1# ifconfig lan1:1 down
server1# ifconfig lan1:1 unplumb
server1# cmruncl

modify the package control scripts to include the oracle occupied filesystems and customer defined functions to start/stop the database.

copy package control script to server2

start your package.

Hope this helps

And since you are doing Oracle, you need to make a fundamental decision. Do you move the Oracle binaries with the package or just the data? That will have an impact upon how you design your shared volume group(s) and logical volumes. There is no "correct" answer to this question but I tend to move the binaries with the data and dedicate a listener for each instance --- but that's just me.

In any event, you can certainly install Oracle and then make it a package. With experience, it is easy to create packages. It's much more difficult to build the MC/SG cluster itself and the monitors for the packages.
