Hi All,

Once the database has been created I changed the default password for System and Sys. But later, just to make sure, when I tried

$ Sqlplus /nolog
$ conn sys/< old password or any other word as password> as sysdba

It is connecting to the database and allowing me to query the dictionary tables. It is really strange to me.

Did I make any mistake? Or I have to do something else to restrict that?

Please give me the solution.
