ABSTRACT:
A method, system, and computer program product for dynamically routing query request messages to a database server resident on a computing system. A configurable port proxy service is created on the database server that listens on a particular port for query request messages. An administrator port is implemented on the database server that communicates with the port proxy service. The configurable port proxy service is pinged by a traffic manager application operating on the computing system to determine if a database server instance is available to send database traffic. Query requests are routed to the database server instance if the database server instance is available to accept query request messages. Each administrator command from a port console application is serialized to a configuration file as it issues that will return the port proxy service to a previous state if the database server fails.
