Abstract: A method and apparatus in a distributed data processing system for managing memory in a data processing system within the distributed data processing system. Responsive to detecting a first level of memory shortage on the data processing system, a first set of monitors is automatically stopped on the data processing system. Responsive to detecting a second level of memory shortage on the data processing system, a second set of monitors is stopped on the data processing system. Responsive to detecting a ceasing of the memory shortage, all stopped monitors are automatically started.

Abstract: A global sign-on system integrates global sign-on functionality into the desktop, such that global sign-on targets can be represented as icons or shortcuts, thus making the desktop a global sign-on environment. Global sign-on may be configured with integrated login so that a user may log into the operating system or network environment and select sign-on targets using the familiar desktop environment. Global sign-on targets may then be selected by interaction with icons or start menu items without having to enter additional identifications or passwords.

Abstract: An event management service (EMS) of a distributed computing environment includes a filter mechanism for determining whether events generated by one or more event suppliers are communicated to one or more event consumers. Each event consumer that registers for the service also defines an event filter group that determines whether particular events generated by the one or more event suppliers are communicated to that event consumer. The event filter group is derived from one or more predefined event type schemas and/or event header information. Events supplied to the service are applied through a parser of the filter mechanism to control whether and where a particular event is routed.

Abstract: A method, instructions and system is provided for establishing and enforcing change password policy in a single sign on environment. In response to receiving a change instruction identifying a first single sign-on password, the first single sign-on password is changed to create a second single sign-on password. Then a target password is retrieved. The target password is modified in a user selected manner to match the second single sign-on password to create a modified target password. The modified target password is stored. In response to a request from a user requesting access to an application, the modified target password is retrieved and the modified target password is provided to the requested application.

Abstract: A frames-based Web browser is used with existing distributed computing environment (DCE) interfaces to facilitate and simplify management of DCE cells. In the preferred embodiment, administration may be performed from any secure Web browser acting as a client. Management data is typically supported on a target Web server. at the browser, CGI scripts are used to dynamic generate HTML (hypertext markup language) pages based on the network administrator's selections and the current state and defined objects in the DCE cell. The result is a robust and efficient Web-based DCE management scheme.

Abstract: A single sign-on (SSO) mechanism to enable a given user to access a target application on a target resource in a distributed computer enterprise. One or more configuration directives each identifying a given logon process and any associated methods required to access the target application on the target resource are stored in a preferably global-accessible database (CIM). For each of a set of users, a preferably global-accessible database (PKM) stores user-specific and application-specific information enabling the user to access and logon to one or more target resources. During a particular session, a logon coordinator (LC) mechanism coordinates given user information with the configuration directive to enable the given user to perform a given action with respect to the target application without specifying the given logon process and the application-specific information.

Abstract: A system and method for controlling client access to enterprise resources through a middle tier server. Enterprise resource authorizations are maintained in a middle tier server. Users authenticate with the server causing it to map and transform the client access authorization into enterprise resource credentials. Enterprise resources are accessed after authorizing using the transformed credentials.

Abstract: An event management service (EMS) operating in a distributed computing environment includes a queueing mechanism for controlling passage of events through an event channel when multiple event consumers cannot consume events being generated by one or more event suppliers as the events are being generated. The queueing mechanism includes a number of queues: an input queue that receives queue elements for each event that reaches the service, an active queue that receives queue elements for each event that any event consumer has registered to receive, and a consumer queue for each event consumer registered to receive any event. A multi-threaded process control routine processes the queue elements to control passage of the events to the event consumers.
