A resource manager (RM) instance is associated with each transaction processing system (TPS) member, of a TPS group. Each RM instance monitors performance of the associated TPS member. If a TPS member becomes unavailable for any reason (a failing TPS), the associated RM instance broadcasts status of the failing TPS to RMs associated 'surviving' members of the group. RM instances associated with surviving members initiate a series of actions that reduce the resources used by the surviving TPS members. Consequently, the surviving TPS members are better able to process the additional workload imposed on them due to the unavailability of the failing TPS. Once the failing TPS is brought back online and made available again (or a replacement TPS is brought online), RM instances associated with the surviving members perform actions to undo the resource usage reduction tasks, and the TPS group returns to a nominal configuration.

Resource manager for transaction processing systems

A method, computer program product and system uses a tiered priority system having three types of callout messages for use by a transaction processing system: (i) callout with a reserved path; (ii) callout with priority; and (iii) default priority callout with sharing mode. An online transaction program (OTP) issues a 'reserve call' associated with a 'callout with a reserved path'. In response, a reserve call processor initiates an asynchronous request to build an express socket path, and returns a special dispatchable unit of work identifier (special DUOW ID). The OTP subsequently issues any number of callouts to be sent on the express socket path using the special DUOW ID. A callout with priority dynamically allocates a path for sending a callout message, without queuing. A sharing mode combines a group of callout messages (types (i), (ii), and/or (iii) above) into a single TCP/IP send without queuing.

Tiered priority system and callout performance booster

A method of and a system for processing an enterpise an application request on an end user application and an application server. This is accomplished by initiating the application request on the end user application in a first language (such as a markup language) with a first application program (such as a Web browser), and transmitting the application request to the server and converting the application from the first language of the first end user application to a language running on the application server, processing the application request on the application server, and transmitting the response from the application server back to the end user application, and converting the response from the language running on the application server to the language of the end user application. The end user application and the application server have at least one connector between them, and the steps of (i) converting the application request from the language of the end user application (as a source language) to the language running on the application server (as a target language), and (ii) converting the response to the application request from the language running on the application server (as a source language) to the language of the end user application (as a target language), each include the steps of invoking connector metamodels of the respective source and target languages, populating the connector metamodels with metamodel data of each of the respective source and target languages, and converting the source language to the target language.
