Add new Application Tier/Node to Oracle Apps/E-Business Suite (11i/R12/12i)

This post covers broad level steps to introduce additional middle/application tier to accommodate more application users or for resilience.
    This document is based on Rapid Clone to add new Application Tier/Node.

.

Top Level Steps

1. Run Rapid Clone (preclone) on existing middle tier Node;
perl adpreclone.pl appsTier

2. Copy middle tier file system from existing middle tier node to target middle tier
For 11i -> APPL_TOP, COMMON_TOP and ORA_TOP
For R12 -> apps and inst from R12_INSTALL_BASE

3. Configure target node you want to add;
perl adcfgclone.pl appsTier

4. Add node to target system using adaddnode
perl adaddnode.pl

5. Setup load balancer  (Optional)

– If load balancer is already in place (using two or more middle tier via load balancer) then reconfigure load balancer to include new node as target apps node

– If this is second middle tier node in your configuration then configure load balancer for existing and new middle tier (Use Metalink Note 380489.1 for R12 and 217368.1 for 11i). Check more on Load Balancer Here

@ Bala,

Option 1
———
1. Just shutdown node and delete file system

Option 2 (Clean Method)
———–

1. Shutdown node which you wish to remove

2. Remove all nodes from fnd_nodes

Connect as apps

SQL> EXEC FND_CONC_CLONE.SETUP_CLEAN;
COMMIT;
EXIT;

3. Run autoconfig on all existing nodes to repopulate fnd_nodes and corresponding nodes

first on Database then Concurrent Manager followed by Middle Tiers

Useful option. I bet that one would work.

Don’t go for RAC or LB setup. Because MRP in EBS 11i/R12 won’t support these setups.

Ref: Note 279156.1 – RAC Configuration Setup For Running MRP Planning, APS Planning, and Data Collection Processes

Extract of this Doc:
“MRP does NOT support RAC for the MRP processes. MRP uses DBMS_PIPES. DBMS_PIPES cannot communicate across nodes. In MRP you can’t do load balancing on the DB and CM node which handles the MRP requests that’s why you have to disable load balancing on those and pin the concurrent manager running the MRP request to that node two_task needs to point to the entry in the tnsnames which does not have load balancing .Two_task needs to point to the entry in the tnsnames which does not have load balancing this is clearly mentioned in the note, section III, point 7

Key Point: The TWO_TASK of the node where these processes will run, must point to the TNSNAMES.ora entry that is for a single instance of the RAC and cannot have LOAD BALANCE setup. ”

Don’t become a prey to this trap.

If anybody facing/fixed this issue, kindly post your experience.
