Abstract
A computer operating system selects a one or two-phase commit procedure for resources to optimize the overall commit process. The optimization utilizes the more efficient one-phase commit procedure when possible and reserves the less efficient two-phase commit procedure for situations where the two-phase commit procedure is required to protect critical resources. If the resources include a protected conversation or two or more resources in the update mode then the two-phase commit procedure is utilized for these resources. Read-only resources or a single resource in the update mode that support one-phase commit are subject to the one-phase commit procedure. To further optimize the overall process, a plurality of resources are registered in a table, which table may reside in the operating system. The registrations include information about the resources and/or work requests which indicate what type of commit procedure is required. Thus, the operating system need not waste time consulting with resource managers after the registrations are made, before deciding what type of commit procedure is required.
