Troubleshooting involves several steps: First, verify the database link's configuration using `SELECT * FROM v$database_link;`. Check the TNS entry, remote database availability (ping the remote host), and ensure the user has the required permissions on the remote database. Also, examine the alert log of both the local and remote databases for further error details. Ensure that the `CONNECT` string is correct and that the user has sufficient privileges on the remote database to execute the DDL statement.
