Balanced input/output task management for use in multiprocessor transaction processing system |
摘要 |
A system and method for balancing database transaction request distribution between various hosts in a multiprocessor transaction processing system is provided. The transaction processing system includes a database and multiple host processors each coupled to at least one database transaction request unit. Database transaction requests sent from the host processors are collectively entered into a commonly-accessible load balancing queue. Each database transaction request is accompanied by a source identifier that identifies the database transaction request unit which initiated the corresponding database transaction request. The queued database transaction requests from the load balancing queue are processed by currently-available host processors, regardless of which host processor initiated the database transaction request. A transaction request acknowledgment for each of the processed transaction requests is created and transferred to the database transaction request unit identified by their respective source identifiers.
