Fast reorganization of connections in response to an event in a clustered computing system
First Claim
1. A method comprising the computer-implemented steps of:
- receiving a notification of an event regarding a clustered computing system;
based on said notification, identifying a pool of connections to said system; and
in response to said event, processing one or more connections from said pool, wherein said processing changes availability of said one or more connections for use by one or more clients for connecting to said system.

Abstract
Techniques for fast recovery and/or balancing of connections to a clustered computing system provide management of such connections by determining a number of connections to load balance across nodes and by triggering creation of such connections. In one aspect, a notification of an event regarding the clustered computing system is received by a connection pool manager, a pool of connections to the system is identified based on the notification, and one or more connections from the pool are processed in response to the event. According to an embodiment, the notification comprises the identities of the service, database, server instance and machine that correspond to the event.

30. A connection management system comprising:
-
one or more set of connections to a clustered computing system, wherein each set of connections is associated with a service that is provided by said clustered computing system; and
a connection pool manager that changes availability of one or more connection from a set of said one or more set of connections for use by one or more clients for connecting to said clustered computing system, based on information that is associated with an event occurring in said clustered computing system and automatically in response to receiving said information. - View Dependent Claims (31, 32)
