Connect to Oracle using SQL*Plus
Enter Username : system, Password: manager and leave the host string blank since it's the local Database . We will learn the need of host string later.
Now we will be creating an user and grant DBA permissions which we will be using for our practice.
Step 1:
Sytax: CREATE USER 'username' IDENTIFIED BY 'password';
Replace username and password with any name and password you prefer.
Example:
SQL> CREATE USER EXFORSYS IDENTIFIED BY EXFORSYS;
User created.
Step 2: Since it's the test database, we will be granting permission as DBA.
Syntax: GRANT DBA TO 'username';
Sample:
SQL> GRANT DBA TO EXFORSYS;
Grant succeeded.
Step 3: Now we will be connecting to the Database using the ID and password we created.
Syntax: CONNECT 'username'/'passowrd';
Sample:
SQL> CONNECT EXFORSYS/EXFORSYS;
Connected.
