Techniques and structures to prevent exhaustion of a database connection pool, including retrieving data from the database connection pool, monitoring the data to determine whether the connection pool is at risk of an exhaustion condition, analyzing the data to determine whether one or more clients accessing the database connection pool are offenders upon determining that the connection pool is at risk and throttling access to the one or more clients accessing the database connection pool upon determining the one or more clients to be offenders.

Connection pool anomaly detection mechanism

Techniques and architectures to provide multiple application servers each having at least one connection agent and at least one enabler agent and at least one database organized as multiple nodes. An error condition between a first connection agent and a first database node is detected. The first connection agent indicates that the first database node is unavailable to stop attempts to access the first database node by a first application server. A first enabler agent periodically checks availability of the first database node. The first database node is indicated as available in response to a pre-selected number of successful attempts to contact the first database node with the first enabler agent. The first database node is accessed with the application server in response to the indication that the first database node is available.

Techniques and architectures for recovering from a service disruption in a multi-server environment

In a computing environment having multiple application servers each having at least one connection agent and at least one pause agent and a database node, detecting an error condition between a first application server from the multiple application servers and the database node. Indicating that the database node is unavailable to stop attempts to access the database node by a first application server. The attempts to access the database node are paused without an indication of the database node being unavailable to a source of the attempt to access the database node. Checking periodically, with the first application server, availability of the database node. Indicating that the database node is available in response to a pre-selected number of successful attempts to contact the database node with the first application server.
