Abstract:
Sending installation information. A method may be performed, for example, in a network computing environment including one or more servers connected to one or more clients. The method includes signing a package including installation information. A hash of the package is created. A metadata data set is created. The metadata data set includes a description of the package, an identification for the package, applicability rules describing intended recipients of the installation information, the hash of the package, and installation instructions for the package. The metadata data set is sent to a target group of systems in the network computing environment.
Abstract:
A hierarchical software update distribution system and method for distributing software updates is presented. The update distribution system includes a root update service node and at least one update service node. In an update distribution system, each update service node, except the root update service node, has one parent update service node. Each update service node may function as a parent update service node to child update service nodes.
Abstract:
Performing software installation activities. A method may be practiced for example in a network computing environment including one or more targetable entities organized into target groups. The method includes beginning a rollout including installation activities to a first set of one or more target groups. At least a portion of the installation activities are evaluated in the first set of one or more target groups. A rollout, including installation activities, to a second set of one or more target groups is begun if the installation activities in the first set of one or more target groups meet predetermined criteria.
Abstract:
A managed network with a quarantine enforcement policy based on the status of installed updates for software on each client seeking access to the managed network. To determine whether a client requesting access has up-to-date software, an access server may communicate directly with an update server to determine the update status of the client requesting access. Information from the update server allows the update server to determine which update the client requesting access is missing. The access server may also receive an indication of the severity of the updates missing from the client requesting access. The access server may use the severity information to apply a quarantine enforcement policy, thereby avoiding the need for either the client or access server to be programmed to identify specific software updates that must be installed for a client to comply with a quarantine enforcement policy. To reduce network congestion and delays seeking access to the network, the quarantine enforcement policy includes a deadline by which updates must be installed. Establishing a deadline allows a grace period during which clients may download new updates and avoids network congestion from multiple clients downloading updates simultaneously.
Abstract:
The present invention is directed to a system and method for managing software updates. More specifically, the present invention is directed to a system and method for facilitating the selection and implementation of software updates while minimizing the bandwidth and processing resources required to select and implement the software updates. In accordance with an aspect of the present invention, a software update service controls access to software updates stored on servers. In accordance with another aspect, the software update service synchronizes with client machines to identify applicable updates.
Abstract:
A system and method for logging events processed by an operating system is provided. The events logged can include interrupt and non-interrupt events, and can include user-defined events. Information concerning the interrupt events is initially written, during event handling time, into a first buffer while information concerning non-interrupt events is initially written, during event handling time, into a second buffer. Information from the two buffers is then written to a third buffer not during event handling time. Separating the interrupt event buffer from the non-interrupt event buffer rather than having one buffer, and writing relatively small amounts of data during event handling time to memory, rather than transporting data to slower non-memory mapped devices allows the event logger to be less intrusive and facilitates greater accuracy in event logging. Data stored in the third buffer can be accessed by a viewing component, which facilitates displaying data in a manner useful to diagnose operating systems.

Abstract:
A tag-based structure for communicating software update metadata information to client computers and to update service nodes is presented. An update metadata file includes: an identifier tag including a software update identifier that uniquely identifies the software update; zero or more general properties tags that carry general property information relating the software update; zero or more localized properties tags that carry localized property information organized according to language; zero or more relationship tags that identify dependency relationships the current software update, as described in the update metadata, has with other software updates; zero or more applicability rules tags that carry information for determining the applicability of the software update to a client computer; zero or more files tags that carry information relating to the software update's payload files; and handler specific data tags that carry information directed to the software handler for installing the software update.
Abstract:
Methods, functional components and structures are disclosed for carrying out management of client/server processes operating within separate process spaces within a computer system. The disclosed methods, functional components facilitate and carry out management of client and server processes within a computer system such that a greater degree of control can be exhibited over their execution. An active server component process maintains a list structure identifying each client process that is currently using one of the server component process's interfaces. When a new client references a server, the list structure is augmented to include the system identification (e.g., handle) assigned by the operating system to the client process. A thread within the server process blocks while awaiting a triggering event (e.g., a client process in the list terminates). When the client process terminates, the block on the thread releases and the thread processes the change in client references. If the list of clients within the structure reaches zero, then the server process can immediately terminate.
