ORA-17630: Mismatch in the remote file protocol version client 1 server 3

I was trying to setup an Oracle Data Guard environment (physical standby) from an Oracle database running version 11.2.0.4 to target oracle db version is 12.2.0.1 using rman duplicate .

Source db : 11.2.0.4
Target db : 12.2.0.1

Solutions :
===============

We need to apply below patch on source 11.2.0.4 db 

p29913194_112040_Linux-x86-64 - Required patch
p18633374_11204190716_Linux-x86-64  - Main patch
p6880880_112000_Linux-x86-64  - required version of opatch 


After apply patch 18633374 to the ORACLE_HOME that was running the SOURCE database, able to proceed with building out the standby successfully using RMAN DUPLICATE with ACTIVE DATABASE


but we need to sysnc then upgrade db on target for open, i will share steps to upgarde in next post .


Always read README before apply any patch .
