Important note: The information in the article below is outdated. It is shown for reference purposes only. Please use the Oracle SQL v2 sensor to monitor databases on your Oracle server.

PRTG Sensors and Connections to Oracle Database Servers

In order to connect to Oracle database servers, PRTG uses the Direct Mode for Oracle sensors. This mode grants considerable advantages in comparison to OCI (Oracle Call Interface). PRTG uses Oracle Net for direct TCP/IP communication. Thus, you do not need to install and administrate Oracle client software. Furthermore, system requirements are reduced.

On the other hand, this mode has some limitations. Compatibility with all Oracle servers and in every network in direct mode cannot be guaranteed, some platforms may cause incompatibility issues, NLS conversion on client side and Transparent Application Failover are not supported, and some additional features are not available. For details, please refer to the following article:

Note: PRTG is only able to monitor against a single instance, but not against a clustered service, because direct mode does not support Oracle RAC (Real Application Clusters).
