We might some time get into below issue after clone or after installing AD and TXK patches.


Error:

                The EBS Technology Codelevel Checker needs to be run on the database node.
                It is available as Patch 17537119.

 Reason:

 It might be due to mismatch in host name between APPS.FND_NODES and APPLSYS.TXK_TCC_RESULTS tables.

 Solution:

 1. Login to the database as APPS schema.
2. Validate the data in FND_NODES  and TXK_TCC_RESULTS  table.

sh checkDBpatch.sh

 or 

 3. Update the correct node name in APPLSYS.TXK_TCC_RESULTS table.
