    摘要： 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.

    摘要： A computer system provides registration of resource for synchronization point processing. Resources include file systems, data bases, and protected conversations. A resource becomes protected by the system when it is registered in the application's execution environment. The execution environment includes but is not exclusive to the interactive environment. Accordingly the invention provides an efficient and uniform method for identification of protected resources. The registration facility is separate from the application. Thus, the users of applications, application program developers, system administrators and operators need not have to consider or design a registration facility but only involve the one provided. A protected resource manager, through its adapter, can modify, at any time, the registration information, either by adding missing information or by changing the existing information. A resource registers only for the work unit in which it wishes to participate. An application could have several work units. A resource can register for two work units in the application or two resources can register for a single work unit or both.

    摘要翻译： 计算机系统提供用于同步点处理的资源的注册。 资源包括文件系统，数据库和受保护的对话。 当系统在应用程序的执行环境中注册时，资源将被系统保护。 执行环境包括但不是交互式环境的排他性。 因此，本发明提供了用于识别受保护资源的有效且均匀的方法。 注册设施与应用程序是分开的。 因此，应用程序，应用程序开发人员，系统管理员和运营商的用户不需要考虑或设计注册设施，而只涉及提供的注册设施。 受保护的资源管理器通过其适配器可以随时通过添加缺失信息或通过更改现有信息来修改注册信息。 资源只能为希望参与的工作单位注册。 一个应用程序可以有几个工作单元。 资源可以在应用程序中注册两个工作单元，或者两个资源可以注册单个工作单元或两个。

    摘要： A prefabricated metal chimney formed of double wall sections which can be connected so that the inner pipe joints are substantially air or smoke tight. The inner pipes of adjacent sections have end flanges which engage and are held together by an inner band member. Attached near each opposite end of the outer wall member for each section is a spacer band with circumferentially spaced apart tab means. Inter tab means extend radially outwardly from the band and is fixed to the outer pipe wall while inner tab means is held to the inner pipe by the inner band member.

    摘要： A metal chimney comprised of prefabricated double-walled sections packed with compressible mineral fiber insulation material between the inner and outer metal walls. Each section has a male end and a female end constructed so that a plurality of sections can be interconnected together end-to-end and will maintain structural integrity while also reducing heat conductivity and gas leakage from the inner wall to the outer wall. The female end of each section has a flexible, diaphragm like insulation retainer and seal, while the male end utilizes a rigid spider comprised of spaced apart spoke portions between inner and outer walls in combination with an annular wafer of thin nonmetallic sheet material. After installation, the flexible diaphragm seal is compressed against the rigid spider and annular wafer allowing the insulation to form a gas seal, which is maintained even if these wafers or diaphragm seals are consumed by chimney heat.

    摘要： An expansion and length adjustment joint for a prefabricated double-walled metal chimney is disclosed. The joint provides for easy installation of the chimney at a job site without cutting of chimney sections. To prevent escape of flue gases, at least one gasket is positioned on one inner wall member for sliding engagement against the other inner wall member.
