摘要： A method is used in managing indications in data storage systems. A threshold value is associated with a storage object. A client subscribes to a server for receiving an indication indicating a change in a property of the storage object. A determination is made as to whether a number of indications processed by the server exceeds the threshold value. A bulk status is associated with the indication based on the determination. The indication is send to the client. The client performs an action based on the bulk status associated with the indication.

摘要： In a multinode computer network, a directory database (DDB) in each of the nodes, contents of the DDB being replicated throughout the network through use of one of its nodes having been appointed as master node. The master node updates each DDB in each node in its network or domain configuration when the configuration changes. A global administrator has authority to replace or select a master node and to configure a domain, and performs these and other functions by way of computer terminal screen dialogs offered by a graphical user interface (GUI) associated with the computer network. In the case of multiple master nodes attempting to be master for the same nodes in the same network at the same time, this conflict is resolved in one embodiment of the present invention by allowing the most recently selected purported master node to be the actual master node. After resolution of this conflict the result is communicated by the prevailing master node to all nodes in the network. This resolution takes into account a global network with varying time zones, and further takes into account the remote possibility of a simultaneous appointment of two masters.

摘要： A data replication facility for distributed computing environments. A computer network having a plurality of network nodes utilizes a distributed directory provider service (DPS) having an established master node. The DPS supports a file replication service (FRS). The FRS establishes one of the nodes as originator node which receives new or updated files from one or more user/GUIs and/or from one or more software providers such as a security provider. The originator node in cooperation with the master node establish a backup copy of the new or updated file in the master node. Thereafter, the originator node publishes a File Version Variable (FVV) representation of the new or updated file to other network nodes (slave nodes) which obtain such file from the originator or, if need be, from the backup master node. Object observers are utilized to determine changes to the file version variables thereby triggering the downloading of new or updated files into the network nodes, whereby data file replication is accomplished throughout the network. In addition to avoiding a single point of failure, embodiments of the present invention also are network-topology independent. Additional syncing threads are employed as part of the file replication service to further ensure synchronization of the network nodes' data files within a predetermined interval, regardless of network failure modes. Embodiments of the present invention are particularly useful with networks of the client-server storage network variety.

摘要翻译：用于分布式计算环境的数据复制工具。具有多个网络节点的计算机网络利用具有建立的主节点的分布式目录提供商服务（DPS）。 DPS支持文件复制服务（FRS）。 FRS建立一个节点作为发起者节点，其从一个或多个用户/ GUI和/或从诸如安全提供商的一个或多个软件提供者接收新的或更新的文件。与主节点协作的发起者节点在主节点中建立新的或更新的文件的备份副本。此后，发起方节点将新的或更新的文件的文件版本变量（FVV）表示发布到从发起方获取这种文件的其他网络节点（从节点），或者如果需要，则从备份主节点发布。利用对象观察者来确定对文件版本变量的更改，从而触发将新的或更新的文件下载到网络节点中，从而在整个网络中完成数据文件复制。除了避免单点故障之外，本发明的实施例也是网络拓扑独立的。额外的同步线程被用作文件复制服务的一部分，以进一步确保网络节点的数据文件在预定间隔内的同步，而不管网络故障模式如何。本发明的实施例对于客户端 - 服务器存储网络品种的网络特别有用。

摘要： A technique for robust indication processing. In client server network environments running object oriented software, there is a need for monitoring the operating state or status of objects in the network. Prior monitoring schemes involved many specific and frequent inquiries or requests of multitudinous objects, for which the connections were constructed and destroyed on an as-needed basis, thereby taking an immense toll on the network's processing capacity. Subsequently, asynchronous monitoring has been employed as an improvement over the prior monitoring schemes, wherein an observer object monitors a subject object and is set at “hair-trigger” to fire back indications to an interested client if and when the subject object's state changes. Asynchronous monitoring limitations include an inability to detect client and/or server failure, insecure and unreliable connections through which indications are intended to be fired back, and other drawbacks. The technique disclosed herein for asynchronous monitoring solves these problems and others by employing a heartbeat polling scheme having virtually unique ID numbers to instantaneously determine if there has been client or server failure or recycling along with a secure or persistent pipe that interconnects client and server and has the ability to tunnel through firewalls when public networks such as the Internet are utilized.
摘要翻译：一种鲁棒指示处理技术。在运行面向对象软件的客户端服务器网络环境中，需要监视网络中对象的运行状态或状态。先前的监测方案涉及许多具体和频繁的多种物体的查询或请求，根据需要建立和销毁连接，从而对网络的处理能力造成巨大的损失。随后，已经采用异步监视作为对现有监视方案的改进，其中观察者对象监视被摄对象并且被设置为“发触发”，以便在对象对象的状态改变时以及何时以及何时对感兴趣的客户端反射指示。异步监视限制包括无法检测到客户端和/或服务器故障，不安全和不可靠的连接，通过该连接可以反射指示，以及其他缺点。本文公开的用于异步监控的技术通过采用具有虚拟唯一ID号码的心跳轮询方案来解决这些问题，以便即时确定是否存在客户端或服务器故障或循环以及连接客户端和服务器并具有当利用诸如因特网之类的公共网络时，通过防火墙隧道的能力。

摘要： In a computer network having a plurality of computer nodes, a directory database (DDB) distributed throughout the network in each of the nodes, the contents of the DDB being maintained consistent or replicated throughout the network in a manner to avoid a single point of failure through the use of one of its nodes having been appointed as master node. The master node has a privileged status as compared to the other nodes. The master node updates each DDB in each node in its network or domain configuration when the configuration changes, such as when a node fails, a network link fails and/or a node is added or removed. A node can be added to or removed from the configuration through the master node or through a non master node. A node can fail under different circumstances in which it may or may not know which node is its master node. A master node can fail and be replaced or can be replaced for other reasons. A global administrator is a privileged user compared to other computer network users who has authority to replace or appoint a master node and to configure a domain, and who performs these and other functions by way of computer terminal screen dialogs offered by a graphical user interface (GUI) associated with the computer network. Replication service includes pinging by the master node of its failed or potentially failed nodes, and participating nodes in the configuration use repetitive polling of their master node to aid it in its pursuit of DDB consistency across the configuration.
