RC-00110: FATAL: ERROR OCCURRED WHILE RELINKING OF APPLYDBTECHSTACK

LSINVENTORYSESSION FAILED: RAWINVENTORY GETS NULL ORACLEHOMEINFO

ORA-39142: incompatible version number 5.1 in dump file.

Solution To above problem.

While taking export from higher version of DB i.e. 12.2.0.1.0 use version parameter in expdp command.

Example
expdp scott/tiger@orcl directory=EXPIMP schemas=scott Version=11.2 dumpfile=Exp_Scott.dmp logfile=Exp_Scott.log

Now, you can import schema without any error.

impdp scott/tiger@orcldg directory=EXPIMP schemas=scott dumpfile=Exp_Scott.dmp logfile=Imp_Scott.log
