    • A method and system for increasing the computational and network efficiency of presence servers having collections of publications is provided. The presence system uses several techniques that enable a presence server to provide rich presence information without requiring expensive processing. First, the presence system accepts batches of publication updates in a single presence update request. Similarly, the presence system accepts batches of subscription requests. Next, the presence system supports new expiration types for publication update requests that eliminate the need for a publishing user to continually refresh presence information that has not changed. Finally, the presence system accepts access lists that contain membership groups rather than an individual list of users that are to have access to a particular presence collection.
    • 提供了一种用于增加具有出版物集合的存在服务器的计算和网络效率的方法和系统。 存在系统使用若干技术,使得存在服务器能够提供丰富的存在信息,而不需要昂贵的处理。 首先,存在系统在单个存在更新请求中接受批次的发布更新。 类似地,存在系统接受批次订阅请求。 接下来,存在系统支持发布更新请求的新的到期类型,消除了发布用户不断刷新尚未更改的状态信息的需要。 最后,存在系统接受包含成员资格组的访问列表,而不是访问特定存在集合的单个用户列表。

    • Components of a distributed server system are configured through replicating configuration data from a central configuration store to server machines. Configuration data is placed in globally identifiable containers or batches. A master replication agent service and a file transfer agent service running in conjunction with a central data storage unit are responsible for replicating configuration data within the batches to other machines in the deployment. A replica replication agent service running on the individual machines updates its own state and posts its latest status back to the central replication services, which upon receiving the status from every machine pushes changes to synchronize the machines with the latest configuration in central store.
    • 分布式服务器系统的组件通过将配置数据从中央配置存储复制到服务器机器进行配置。 配置数据放置在全局可识别的容器或批次中。 与中央数据存储单元一起运行的主复制代理服务和文件传输代理服务负责将批中的配置数据复制到部署中的其他机器。 在单个计算机上运行的副本复制代理服务将更新其自身的状态,并将其最新状态发布回中央复制服务,这些服务在从每台机器接收到状态后,将更改同步到中央存储区中的最新配置。

    • Disclosed is a rollback-free method for performing multi-step procedures in the presence of possible failure. As the procedure proceeds from its initial state through transitions to its final state, its constituent transitions are monitored for failure. If a failure is detected, then the procedure is “sidetracked” into a recovery coordination state. From the recovery coordination state, the procedure is logically taken back to its initial state and retried. In this manner, the procedure is shepherded, without rollbacks, through its transitions until it successfully reaches its final state. In a particular embodiment, a multi-step procedure is developed for moving a resource from one resource server to another. The steps of the procedure are designed so that all throughout the procedure, both of the resource servers and a directory server are kept synchronized. This allows client requests to proceed without interruption even during the resource movement.
    • 公开了一种用于在存在可能的故障的情况下执行多步骤过程的无回滚方法。 随着程序从初始状态转移到其最终状态,其组成转换被监控失败。 如果检测到故障,则该过程被“侧向”到恢复协调状态。 从恢复协调状态,该过程在逻辑上被恢复到其初始状态并重试。 以这种方式,该过程在没有回滚的情况下,通过其过渡被保护,直到其成功地达到其最终状态。 在特定实施例中,开发了用于将资源从一个资源服务器移动到另一个资源服务器的多步骤过程。 该过程的步骤被设计为使得整个过程中的所有资源服务器和目录服务器都保持同步。 这允许客户端请求即使在资源移动期间也不中断地继续进行。

    • A system, apparatus, method, and computer-readable media are provided for efficient database lookup operations. According to method, procedural checks for generating a response to a database query are converted into a set of database operations. The database operations are performed the first time a query of the database is received to generate a set of possible results for the query. The set of possible results for the query are then stored. A specific answer to the query is generated from the set of possible results. Future database queries are responded to by generating an answer to the query from the stored set of possible results.
