While doing import got the below error :

With the Partitioning, OLAP, Advanced Analytics and Real Application Testing 
ORA-31626: job does not exist
ORA-31637: cannot create job SYS_IMPORT_SCHEMA_02 for user SYS
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95
ORA-06512: at "SYS.KUPV$FT", line 1580
ORA-39062: error creating master process DM00
ORA-31613: Master process DM00 failed during startup.

When we checked the alert.log, we found that maximum process has been reached.

Solution:

Increase the processes and bounce the db.

SQL> alter system set processes=800 scope=spfile;

System altered.

SQL> startup force
ORACLE instance started.
