oracle changes user password

Oracle is a relational database management system that is widely used in enterprise-level database management. In Oracle, the user's password is very important and needs to be changed regularly to ensure security. This article will introduce how to change the password of Oracle user.

1. Use the sqlplus command to log in to the Oracle database

First, use the sqlplus command to log in to the Oracle database and enter the following command:

sqlplus /nolog

Then enter the following command to log in to the Oracle database:

SQL> connect /as sysdba

You will need to enter the sysdba authorized user name and password to log in to the Oracle database.

2. Use the ALTER USER command to change the password

Next, use the ALTER USER command to change the user's password. In this example, we will change the password of user TEST.

SQL> ALTER USER TEST IDENTIFIED BY "new_password";

You need to replace "new_password" with the new password you want to set.

3. Check whether the password has been changed successfully

Finally, use the following command to check whether the password has been changed successfully:

SQL> SELECT USERNAME, ACCOUNT_STATUS FROM DBA_USERS WHERE USERNAME ='TEST';

If the password has been changed, OUTPUT will return "OPEN" status.

It is very important to modify the Oracle user password to protect the security of the database. By using the above steps, administrators can easily change user passwords. Testing whether the new password is available can ensure that users can easily log in to the database and provide better protection for the database.
