APPS R12.1.1 post cloning for Database Tier error - ORA-12547: TNS:lost contact


On post cloning of database tier of APPS R12.1.1 , it ended with errors "ORA-12547: TNS:lost contact"


Following were the errors which we got in ApplyDbTier.

Executable : /erptst/TST/db/tech_st/11.1.0/bin/sqlplus

The log information will be written to

ORA-12547: TNS:lost contact
SP2-0640: Not connected

We tried to connect from sqlplus but after few seconds of wait it again gave the same error.

We checked the inventory location and permission and it was all ok.

We tried again the post clone, but this time we choose the different SID as CLN and gave the different port number, previously it was 01 and this time we chose 79. And this time the post clone went successful without any errors, this is so weird, but this is just what happened!
