single node to multi node

[Brian Hogantara]

Hi erman,

do you know how to make a single node(apps and database in one server) to become a multi node(apps in one server and database in another server) from oracle ebs 12.2.6 ? or do you have a link or document that relate to "clone from single node to multi node step by step"?

first of all, i do the cloning steps.
what's next?

This is called split configuration.
You will execute the standard cloning process.
You will not touch the db. (if you just want to leave the db in the current node and migrate the apps tier in to a new node)
You will only clone the apps tier to your target/new apps node and execute post clone to connect it to the db.

("Don't do" 4- Add the additional application tier secondary node, "also don't do" step 2 P-erform a full clone (including the prepare, copy and configure steps) of the database tier node --if you are planning to  leave the db tier in the source node/current node)

"You will execute the standard cloning process"

what conditions i must or can doing the cloning process? i means, this steps can be done when you have apps and db in single node, right?

"(if you just want to leave the db in the current node and migrate the apps tier in to a new node)"

did you means i can migrate db to another server?

from the explanation you describe, the point that i get :
-you must have apps and db in single node(why? because you suggest standard cloning process)
-you can either clone apps only and migrate to a new server or you can clone and migrate both(apps & db) to a new node(different node between apps & db)

Cloning is documented Brian.The question that you asked, is not a hard one.
read -> Cloning Oracle E-Business Suite Release 12.2 with Rapid Clone (Doc ID 1383621.1)

Also, it is your choice to have a single node or to have a split node configuration.
You can place apps and db in seperate nodes/or you can place apps and db in the same node.
But, you want a split node configuration, right?
split means -> apps and db in seperate nodes.

so now, your apps and db are in the same node
so you have 2 choices. Actually it is according to your decision & plan.

1)
you migrate apps to a new apps server.
db will stay in the same server, as it now resides.
In this case, you will copy the apps fs to new server, but copying is not enough , you need to execute preclone before it and post clone after it.. So it is like cloning.

2)
you migrate apps to a new apps server.
you migrate db to a new db server as well.

In any case, you will execute the cloning commands, again you will executes copy commands. And If you will migrate the db to a new server , you will also take a rman backup (preffered way) and restore it.. You will execute postclone on db.

Can we follow the same steps for two node rac DB + apps on master node(one of rac node) ?

Srinivas,

What you need to is cloning.
It the same.
Your apps node target environment  will be a new apps server.
Your db node target environment will be a 2 node RAC.

So, you will clone your database by following the cloing document that I already mentioned above.
Then you will clone your apps tier by copying the files and running post clone basically.
