Steps to Clean Nonexistent Nodes or IP Addresses from FND_NODES

Here we will discuss how to clean fnd_nodes table in oracle apps.

SQL> EXEC FND_CONC_CLONE.SETUP_CLEAN;

After complete clone in E-Business suite, if FND_NODE system tables will show incorrect values.

If a clone was done, the OAM Dashboard reflects the target machine name and the source machine name although the source machine is no longer being used.

In some cases, there are IP addresses from nonexistent machines in FND_NODES.

The Nodes in the OAM Dashboard are retrieved from the FND_NODES table.

Further investigation showed that the FND_NODES table had both node names and node_modes 'O' as activated.

To check fnd_nodes table value.

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

How to Clean fnd_nodes table : 
------------------

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 dbTier and then the appsTier,to repopulate the required system tables.

Once we will execute the EXEC FND_CONC_CLONE.SETUP_CLEAN, it 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 once AutoConfig will successfully completed.
