Note: Database has been upgraded from 12c to 18c that’s why we are getting above error.

 

Solution :

--------------OLD 12c ORACLE_HOME--------------------------

[oracle@test_server lib]$

 

[oracle@test_server lib]$ ls -lrt *libobk.so*

lrwxrwxrwx. 1 oracle oinstall 21 Nov 15  2017 libobk.so -> /usr/lib/libnsrora.so

 

[oracle@test_server lib]$

[oracle@test_server lib]$

[oracle@test_server lib]$ pwd

/applications/oracle/12.1.0.2/dbhome1/lib

 

 

 

 

---------------NEW 18c ORACLE_HOME ------------------------

 

[oracle@test_server]$ cd $ORACLE_HOME/lib

 

[oracle@test_server lib]$ pwd

/applications/oracle/18.3.0.0/dbhome2/lib

 

[oracle@test_server lib]$ ls -lrt *libobk.so*

lrwxrwxrwx 1 oracle oinstall 21 Jun 27 12:20 libobk.so -> /usr/lib/libnsrora.so

 

Run below command to Link the library file

 

[oracle@test_server lib]$ ln -s /usr/lib/libnsrora.so libobk.so 

 

Now run the RMAN backup once again …!!!
