Thanks Shaik and Althaf,
I got phobia in applying AD-TXK since it entails complex process and has lots of pre-reqs patches
Is it different this time? If I apply it in 12.2.4 is it only a simple one patch?
You can safely apply the latest patches.
run the etcc and apply the missing patches and proceed to apply latest TXK
Does ETCC check the latest updates of patches in the Oracle website?
Do I need to run in on-line?
or does my server need to connect to the internet?
Or internet is not needed at all and my EBS server can be is stand-alone and disconnected from internet and it is still okay to run ETCC.
Regarding the ETCC Patches, review following MOS Notes:
How To Run The 12.2 EBS Technology Code Level Checker (ETCC) ? (Doc ID 2008451.1)
1) For applying the ETCC Patches, the services should be down as these patches are applied on the Technology Stack
2) You need not be connected to the internet to apply these patches.
Thanks Narsi and ALL
