摘要： A method and apparatus for dynamically reconfiguring a server system. When a new server configuration is applied, a previous server configuration is saved. When receiving a service request, a first server is selected by using a first scheduling algorithm according to the new configuration. If the selected server is incorrect, a second server is selected by using a second scheduling algorithm according to the saved previous server configuration. User data associated with the received service request is moved from the second server, if correct, to the first server. In this way, stored data will be gradually and dynamically reorganized from the previous configuration to the new configuration in a relatively simple way.

摘要： Embodiments of the present invention are directed to a method, system and apparatus handling a request for a media-over-packet communication session. The method comprises receiving a request for a media-over-packet communication session destined for a network address. Responsive to determining existence of an active communication session with a first communication client registered to the network address, the method further comprises determining an identifier associated with a second commmunication client registered to the network address, the second communication client different from the first communication client; and routing the request to the second communication client using the identifier.

摘要： A method and apparatus for serving content requests using global and local load balancing techniques is provided. Web site content is cached using two or more point of presences (POPs), wherein each POP has at least one DNS server. Each DNS server is associated with the same anycast IP address. A domain name resolution request is transmitted to the POP in closest network proximity for resolution based on the anycast IP address. Once the domain name resolution request is received at a particular POP, local load balancing techniques are performed to dynamically select the appropriate Web server at the POP for use in resolving the domain name resolution request. Approaches are described for handling bursts of traffic at a particular POP, security, and recovering from the failure of various components of the system.

摘要： A method, system and computer program product for dynamically establishing a client's Time Sharing Option (TSO) and/or Interactive Productivity System Facility (ISPF) session and maintaining the client's TSO/ISPF session on a zero-downtime/operating system (z/OS) host over multiple service calls. A session provisioning and maintenance (SPM) utility determines whether a TSO/ISPF session exists for a client making a request for a TSO/ISPF service. When a TSO/ISPF session does not exist for the client, session establishment is initiated by generating a TSO initialization module in a new UNIX System Services (USS) process. Session establishment involves initializing a user's own TSO address space through USS and using USS service call API's to make TSO/ISPF service call requests in the TSO address space. The SPM utility maintains the client's TSO/ISPF session over multiple service calls, bypassing the overhead of having to establish a new session for every service request which requires TSO/ISPF services.

摘要： A server capable of reducing an overloaded state even if a refreshing message is frequently generated. A central processing unit receives a first message transmitted from a terminal to establish a session. The central processing unit, when receiving the first message from the terminal, allocates to itself and the other plural central processing units the subsequent message transmission and reception between the terminal and a terminal as a communication partner. The central processing unit allocates to itself and the other plural central processing units the message transmission and reception between the terminals, for example, in a round robin fashion.

摘要： A method for scheduling access to resources of a database is disclosed. Users logon to initiate database sessions. Commands received from a database sessions cause tasks to be initiated. Each task is classified in one of a first set of groups based at least in part on one or more logon account attributes associated with the session that initiated the task. A weight is assigned to each group of the first set of groups. Each task is classified in one of a second set of groups. Each group in the second set of groups is assigned a weight. Each task's access to processor resources of the database is limited based at least in part on the weight of the group from the first set in which that task is classified and also based at least in part on the weight of the group from the second set in which that task is classified.

摘要： Ensuring that a given transactional unit of work arrives at an appropriate server instance. A server instance receives a request that is associated with a unit of work. The server instance that received the request determines whether it is responsible for the unit of work associated with that request. When the server instance is responsible for the unit of work, the server instance processes the request. When the server instance is not responsible for the unit of work, it attempts to register its interest in the unit of work. If this attempt is successful, then the server instance can process the request. If the attempt is unsuccessful, then the responsible server instance is located and the request is forwarded to the responsible server instance.

摘要： A method is described that involves identifying which session a received request pertains to. The method also involves referring to information maintained for the session. The information comprises first information that identifies a queue that provides notifications of requests to a worker node that is assigned to handle the session. The method also involves entering a request for a session into a shared memory. The method also involves entering a notification of the request into the queue. The method also involves, after failure of the worker node, retracting the notification from the queue, and, identifying a new worker node to handle the session with a load balancing algorithm.

摘要： A system, for use with a first application concurrently operating together with a second application, includes an activity manager and a communication processor. The activity manager intermittently receives data identifying activity associated with the first application, and determines that the first application is inactive in response to a first application timeout window being exceeded because of insufficient activity associated with the first application. The communication processor communicates to a managing application an indication that the first application is inactive, and receives from the managing application an indication that the second application is inactive determined in response to a second application timeout window being exceeded because of insufficient activity associated with the second application.
摘要翻译：用于与第二应用并行操作的第一应用的系统包括活动管理器和通信处理器。活动管理器间歇性地接收识别与第一应用相关联的活动的数据，并且由于与第一应用相关联的活动不足，确定第一应用程序响应于超过第一应用超时窗口而不活动。通信处理器向管理应用程序通信第一应用程序处于非活动状态的指示，并且从管理应用程序接收响应于由于与第二应用程序相关联的活动不足而响应于第二应用程序超时窗口而确定第二应用程序无效的指示应用。
