A semi-automated availability-assessment system and methodology. A comprehensive questionnaire providing detailed information about the hardware and operating-system components and configuration of a system, application-and-database-software components and configuration of the system, data related to other potential sources of unplanned downtime, and data related to potential sources of planned downtime is received. The information contained in the received questionnaire is processed in several steps. First, hardware and operating-system-component-and-configuration information is extracted in order to conduct a Markov-chain availability analysis of the overall system hardware and operating system to provide a first intermediate result. Application-and-database-software component and configuration information, along with data and estimates related to software component failure and recovery rates, as well as relevant data for other potential sources of unplanned downtime, are extracted from the questionnaire and compiled together to form a second intermediate result. Information related to maintenance and other planned activities that result in planned system downtime are extracted from the questionnaire and compiled together as a third intermediate result.

A generalized architecture for a highly available transaction processing system that combines commercially available components and software components specifically developed to implement the architecture into an integrated, highly available transaction processing system that minimizes planned and unplanned downtime, minimizes data loss in the event of failures, provides proactive monitoring of both hardware and software components of the highly available transaction processing system, provides automated recovery actions that involve fast failover, either locally to an Inactive Node, or remotely to a Standby Site, and provides an easy-to-use graphical-user-interface-based management interface that provides service-oriented views of the state of the system, with context-directed commands and meta-commands to guide managers in execution of their tasks.

A database system facilitates quick failover. The database system includes a primary node, a standby node and a fast interconnect between the primary node and the standby node. The primary node includes a primary buffer pool which stores pages of the database information, and a log storage which receives a log of updates for the pages within the primary buffer pool. When a page is to be updated by a primary node, the primary node sends a copy of a before update image of the page to the standby node. When the primary log writes logs of updates to the log storage, the primary node also forwards the logs of updates to the standby node.
