ORA01017

ORA01017 is an Oracle Database error message that indicates a failure to connect to the database. This error typically occurs when the username or password provided during the connection attempt is incorrect. The error message reads: "ORA-01017: invalid username/password; logon denied."

This error can be caused by several factors, including:

1. Typographical errors in the username or password.

2. Incorrect case sensitivity, as Oracle usernames are case-sensitive.

3. The user account being locked due to multiple failed login attempts.

4. The user account being expired or disabled.

5. The user account not having the necessary privileges to access the database.

To resolve this error, users should:

1. Double-check the username and password for accuracy.

2. Ensure that the correct case is used for the username.

3. Contact the database administrator to unlock the account if it has been locked.

4. Verify that the account is not expired or disabled.

5. Ensure that the user has the necessary privileges to access the database.

If the issue persists after these steps, further investigation by a database administrator may be required to identify and resolve the underlying cause.
