MULTINODE INSTALLATION ARCHITECTURE STEPS AND CONCEPTS in R12.1.3

Hey DBA-Mates,

Multinode installation concept is very important which we should know it. But many times we got confused. Every time we read documents but after some time either we forget or got confused.

Many fresher asked me about this and I always told them to read documents which is not clear to them. Then at last I found a clear picture to describe them like this below which is from my real time experiences.

There are 3 cases can be found to install multinode, which I am going to describe below here:

CASE-1:

Node-1:  Database Server                                  Node-2: Application Server

       Edit Services                                                                 Edit Services

Disable all                                                                 Enable All

Add Server -2.                                                 Give path of Configuration file

OR

      Hostname:SID:portno.

 

Please find the below screens shot for more details. I have given below important screens shots to clear the described theories. If anyone need some more screens shot for installation, please let us know we can send it to their personal id or in comments.

In above description Case-1, there are 2 nodes in which on 1^st node is Database Server and 2^nd Node is Application Server.
So, here during installation time we have to keep some points in our mind such as:
For database Server: Click on Edit Services and disable all.
And then Click on Add Server and put 2 because we are going to Install 2 node as mentioned above.

 

For Application Server: Click on Edit Service and Enable all.
And another thing either give configuration file path through Browsing or type 
your hostname:SID:portno 

CASE-2:

Node-1: DB Tier and CM Process      Node-2: Apps Tier (Form & Web Services)

Batch Processing--> ENABLE                      Batch Processing--> DISABLE

Remaining--> DISABLE                                Remaining--> ENABLE

Add Server – 2. 
In case-2, here DB (database) and CM (Concurrent process) are on 1^st node and Apps Tier (Forms and Web Services) are on 2^nd Node.

In this case, on Node-1: Enable on batch Processing and disable all other services.

Then here also Add Node as 2.

On Node-2: As shown above Batch Processing should be Disable and other all services should be Enabled.

CASE-3:

Node-1: DB Tier           Node-2: CM Processing Tier                   Node-3: Apps Form Tier

Edit Services                  Batch Processing-->ENABLE            Batch Processing-->DISABLE

  -Disable All                    Remaining--> DISABLE                           Remaining--> ENABLE

Add Server – 3.

In above Case-3: There are 3 Nodes.

On Node-1: DB Tier, in this clicks on Edit Services and Disable all services.

Node-2: CM processing Tier, in this click on Edit Services and Enable Batch Processing and then disable all other process.

Node-3: Apps Form Tier, in this Batch processing should be Disabled and other services should be Enabled.

Hope this will be very clear and easy steps to remember for Multinode Installation steps and concept. I tried to explain this in easy steps in picture format.
