We are trying to connect DB2 via oracle 12C gateway, If DB2 user is administrator so oracle db can connect multiple sessions with DB2 via dblink but if DB2 users is not administrator so we cant connect more than two sessions and give error as below:

ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
