Cause: This error occurs when we forget  to execute ./datapatch -verbose after applying patch to oracle home (Database PSU 12.1.0.2.2, Oracle JavaVM Component).

 

Solution:  Use below procedure for both stand alone and pluggable database. Standalone DB Single/Multitenant (CDB/PDB) DB $sqlplus /nolog SQL> connect / as sysdba SQL> startup SQL> quit $cd $ORACLE_HOME/OPatch $ ./datapatch -verbose $sqlplus /nolog SQL> connect / as sysdba SQL> startup SQL> alter pluggable database all open; SQL> quit $cd $ORACLE_HOME/OPatch $./datapatch -verbose   OR    You may require to put the database in upgrade mode to run “datapatch -verbose” command after applying OJVM patch. For this, put your database in upgrade mode.   SQL> shut immediate; SQL>startup upgrade; SQL> quit $cd $ORACLE_HOME/OPatch $ ./datapatch -verbose SQL> shut immediate; SQL> startup;
