Dear All,
Apologies for late reply issue is solved after running below commands.
Grant sysoper to system;
Grant sysdba to system:
Issue was with user system permissions, but HP dp was giving error as invalid user id and password which was misleading, actually it should give error as ORA 01031 but it was giving ORA-01017 which was wrong, luckily i tried giving permissions to user system and problem solved.
Thank you all for your support.
Thanks
Tabrayz
