To understand this issue, it is important to know what a gateway is. A gateway is a system that allows communication between two different networks or systems.

First, check the gateway configuration and ensure it is correctly configured to access the database. This can include verifying the database link and gateway connection settings. Additionally, check the network connection for any issues that may be affecting the connection. This can include checking the firewall and network settings for any restrictions or blocking.

If the configuration and network are correct, double-check the login credentials for the database. Ensure that the login credentials are correct and that the user has the necessary permissions to access the database through the gateway.

If the problem persists, it is recommended to contact Oracle support for further assistance. They have extensive knowledge and experience in resolving complex issues related to Oracle databases and can provide additional guidance on how to resolve the Oracle 12564 error.

In conclusion, the Oracle 12564 error can be frustrating when attempting to connect to a database through a gateway system. However, by following the steps outlined above and contacting Oracle support if necessary, this error can be resolved and users can access data from external sources with ease.
