Clean FND_NODES table after cloning in Oracle APPS R11/R12

Why we need to clean FND_NODES table post cloning by firing

 EXEC FND_CONC_CLONE.SETUP.CLEAN ?

Ans
-----
Because this table contains the IP Addresses of the source servers (apps and db) and when you clone your target servers have different IP Addresses that need to be populated in FND_NODES table.

Steps to Clean Nonexistent Nodes or IP Addresses from FND_NODES 

How to Clean :
------------------

SQL> select node_name, node_mode, support_cp, support_web, support_admin,support_forms from FND_NODES;

NODE_NAME              N S S S S
-----------------------------------------------
TARGET                     O Y Y Y Y
SOURCE                     O Y Y Y Y


1) Always apply the latest cloning patches, to avoid all the bugs and fixes

2) SQL> EXEC FND_CONC_CLONE.SETUP_CLEAN;
    COMMIT;
    EXIT;


3) Run AutoConfig on all tiers, firstly on the DB tier and then the APPS tiers,to repopulate the required system tables.



Note that step two will delete all data from system tables such as
FND_NODES, FND_OAM_CONTEXT_FILES, etc.


The correct information for the current system will be repopulated when AutoConfig is run.
