Abstract: A system and method in accordance with the present invention provides a 3-phase commit client-server protocol that allows the EIS server to detect the sick-but-not-dead situations, identify the resources involved, determine its degraded level, take the actions if needed, and send out a degraded status information message to the client. In a system and method in accordance with the present invention an internal availability monitor analyzes the resources that have not been externalized, such as storage pools, control blocks, etc, and are therefore not available to external monitors.

Abstract: An apparatus, system, and method are provided for automatically freeing locked server resources using a timeout value closely related to actual real-time message delays plus a delta value that can be adjusted at a plurality of levels. The levels include default, server, connection, and transaction. The apparatus includes a timer, a communication module, a computation module, and a lock handler. The timer determines a timeout value for communications from a client to a server. The communication module sends an output message to the client and locks a server resource in anticipation of an acknowledgement (ACK) message from the client. The computation module, which calculates an ACK timer, includes a difference between a send time and a current time. If no ACK message has been received from the client and the ACK timer exceeds the timeout value, the lock handler may free the locked server resource.
