I figured out from your post that I need to change the character-set of the database. But on executing the statement, I get the error:- ALTER DATABASE CHARACTER SET INTERNAL_USE AR8MSWIN1256; QL Error: ORA-12718: operation requires connection as SYS 12718. 00000 - "operation requires connection as SYS" *Cause: This command can only be run when connecting as SYS *Action: Connect as SYS to run this command Since, I dont know the password for sys, I changed the password using the following command:- alter user sys identified by sys; The above command executes successfully. But, when I try to connect with username and password sys, it gives me the error:- ORA-12526, TNS Listener: all appropriate instances are in restricted mode.
