Prompt Title: ORA-01017 Error Solution.

ORA-01017 is an Oracle database error indicating that the provided username and/or password is incorrect when attempting to connect to the database. To resolve this issue on Windows 10, you can follow these steps:

1. Verify your credentials: Ensure that you have the correct username and password for the Oracle database you're trying to connect to. Double-check for any typos or case sensitivity.

2. Check the tnsnames.ora file: Locate your tnsnames.ora file (usually found in the %ORACLE_HOME%\network\admin directory) and verify that the service name or SID specified in the file matches the database you're trying to connect to.

3. Check Oracle services: Ensure that the Oracle services are running on your machine. Press Win+R, type services.msc, and press Enter. In the Services window, look for Oracle services (such as OracleServiceORCL or OracleOraDb11g_home1TNSListener) and make sure they are running. If not, right-click and choose 'Start' to start the service.

4. Reset your password: If you still cannot connect and are unsure of your password, you may need to reset it. To do this, connect to the database as a user with DBA privileges (e.g., SYSTEM or SYS) using a tool like SQL*Plus, SQL Developer, or any other Oracle client. Then, execute the following command to reset the password:

   phpCopy code
   ALTER USER <username> IDENTIFIED BY <new_password>;
   

   Replace <username> with your actual username and <new_password> with your desired new password.

5. Check for database restrictions: If you still cannot connect, there might be restrictions in place, such as account locking or IP restrictions. Contact your database administrator to verify and resolve any issues.

After going through these steps, you should be able to resolve the ORA-01017 error and connect to your Oracle database.
