How do I change the password of an Oracle database user?
1. Log in to the SUSE Linux as user oracle.
2. On the command line interface (CLI), run the following command to connect to the Oracle database:
$ sqlplus / as sysdba
The user name and password are required in remote login mode. The following describes how to use the command to connect the system user to the Oracle database with password testpwd.
$ sqlplus system/testpwd as sysdba
If the information similar to the following is displayed, the system user is connected to the Oracle database:
3. Run the following command to change the password of the database user system:
> alter user system identified by testpwd;
The method of changing other Oracle user passwords is the same as the method of changing the password of the database user system. To be specific, system is the database user name to be changed, and testpwd is the password of the user-defined system user.
To ensure user password security, design passwords that meet the complexity requirement and modify the passwords periodically.
If the return value is User altered, the password is successfully changed. Otherwise, locate the cause as prompted.
