What Is Default Sysdba Password In Oracle 19C?

Default User Name and Password for SYSDBA

When you install the system, a default user named SYSDBA is created, and it comes with a default password. In this case, the default password is “masterkey,” but it’s essential to note that only the first eight characters of the password are considered. So, effectively, the password is “masterke,” and any characters beyond the eighth are ignored.

For security reasons, if your server is connected to the Internet or any other potentially vulnerable network, it is highly recommended that you change the default password as soon as possible. You can do this using the “gsec” command-line utility, which allows you to set a more secure password to protect your system from unauthorized access.

To access the SYSDBA account in Oracle Database 19c, there are two primary methods available:

1. Using SQL Developer:
   To initiate a connection as SYSDBA using SQL Developer, follow these steps:

   • Launch SQL Developer.
   • Create a new database connection or select an existing one.
   • In the connection configuration, make sure to choose the SYS user.
   • Specify the role as SYSDBA.
   • Enter the required login credentials.
   • Click “Connect” to establish the connection.

2. Using the SQL Command Line:
   If you prefer to use the SQL Command Line, you can do so by entering the following command, taking into account the desired authentication method:

   • For database authentication, use the following syntax:

     sql
     SQL> CONNECT SYS/<password> AS SYSDBA;
     

   • If you want to employ operating system authentication, simply use:

     sql
     SQL> CONNECT / AS SYSDBA;
     

These methods allow you to access the SYSDBA account in Oracle 19c, enabling you to perform administrative tasks and manage the database effectively.
