摘要： Application access to locally and remotely exported file systems is coordinated to allow caching data for exported file systems accessed by remote clients. In response to a request or file system access, it is determined whether the request relates to a locally exported file system or a remotely exported file system. If the request relates to a locally exported file system, a local access routine is invoked to obtain access permissions to the locally exported file system. If the request relates to remotely exported file system, a remote access routine is invoked to communicate with a local access routine in a file server responsible for coordinating access to the remotely exported file system to obtain access permissions to the remotely exported file system.

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 method and system for integrating migration level two (ML2) and backup tape processing provide for the backup, archival, and/or restoration of ML2 tape files without the use of tape mounts. In this manner, the amount of data movement required to recover from data loss is significantly reduced. Tape files may be recovered to their original status, even if the file has migrated to ML2. The status of the data is preserved after such a recovery operation. In this manner, data movement is reduced because no remigration of data is required after a recovery.
摘要翻译：用于集成迁移二级（ML2）和备份磁带处理的方法和系统提供了不使用磁带安装的ML2磁带文件的备份，归档和/或恢复。以这种方式，从数据丢失恢复所需的数据移动量显着减少。磁带文件可能恢复到原始状态，即使文件已迁移到ML2。在这种恢复操作之后，数据的状态被保留。以这种方式，数据移动减少，因为在恢复之后不需要数据的迁移。

摘要： A computer system or network tailors scopes of commit processing by using local work unit identifiers and more global logical unit of work identifiers. The local work unit identifiers are used to identify the scope of commit processing within each execution environment, and the logical unit of work identifiers are used to identify related work units of different execution environments. The related work units are coupled to each other by a protected conversation between the execution environments.
摘要翻译：计算机系统或网络通过使用本地工作单元标识符和更多的全局逻辑工作标识符来定制提交处理的范围。本地工作单元标识符用于标识每个执行环境中的提交处理范围，并且使用工作标识符的逻辑单元来识别不同执行环境的相关工作单元。相关的工作单元通过执行环境之间的保护对话彼此耦合。

摘要： In a computer system or process, sync point managers are distributed throughout each real machine for a plurality of execution environments, but all of the execution environments and sync point managers within one real machine share a common recovery facility and recovery log. A common recovery log is used by the recovery facility for all of the execution environments in the system. Different systems are interconnected by a communication facility and each has its own recovery facility and recovery log. A protected conversation can be initiated between the first and second execution environments in the same real machine, and the sync point managers within the respective execution environments coordinate the two-phase commit procedures associated with the protected conversations. A conversation manager within each real machine assists in routing the conversation between the first and second execution environments. Each resource manager, whether residing inside or outside of the real machine, has its own recovery log, but uses the recovery facility of the real machine that accesses the resource.

摘要： To recover a failed commit procedure, a first recovery facility collects and compares sync point state information from a variety of different types of resources including a data repository and a protected conversation. The comparison of the sync point state information is made automatically in response to a sync point failure event. A second recovery facility serving another execution environment notifies the first recovery facility after a failure and subsequent recovery procedure of the second execution environment has completed. The first recovery facility makes automatic cyclic attempts to communicate with the second recovery facility. The first recovery facility can receive a manually initiated but automatically simulated response of sync point state information when there is a failure such that actual sync point state information cannot be received. The first recovery facility is responsive to the simulated sync point state information to proceed with a recovery operation substantially as if actual sync point state information were received.
摘要翻译：为了恢复失败的提交过程，第一恢复设施收集并比较来自各种不同类型资源的同步点状态信息，包括数据存储库和受保护对话。响应于同步点故障事件自动进行同步点状态信息的比较。服务于另一执行环境的第二恢复设施在故障之后通知第一恢复设施，并且第二执行环境的后续恢复过程已经完成。第一个恢复设施进行自动循环尝试与第二个恢复设施进行通信。当存在故障时，第一恢复设施可以接收到同步点状态信息的手动启动但自动模拟的响应，使得不能接收到实际的同步点状态信息。第一恢复设施响应于模拟的同步点状态信息，以基本上如同接收到实际的同步点状态信息那样进行恢复操作。
