Under the present invention, the performance of a set of system resources is monitored in response to incoming request traffic. When a system resource is approaching an overload condition, a corrective action is identified and implemented. Overload thresholds for each system resource and appropriate corrective actions are contained within a management policy. Based on a performance history of the corrective actions, the management policy can be changed/revised.

An autonomic component installation system. The system can include a catalog of host components installed within a computing system and an autonomic installer coupled to the catalog and programmed to determine, when installing an upgraded component, whether the upgraded component provides component capabilities required by the host components in the catalog. The catalog can include both host components and respective publicly accessible data, method implementations and method prototypes provided by the host components. Consequently, the autonomic installer can determine whether the upgraded component will have access to required publicly accessible data and method implementations. The autonomic installer further can be configured to determine whether modifications included in the upgraded component have caused changes in associated method prototypes which differ from the method prototypes in the catalog. Finally, a machine-readable ReadMe file processor can be coupled to the autonomic installer to identify the required publicly accessible data and methods implementations.

Dependency management when upgrading application components

A method for the autonomic management of autonomic systems can include monitoring a managed system and recommending a course of action to be performed in the managed system. It can be determined whether the recommended course of action has been performed by an administrator. Responsive to the determination, it further can be determined whether an outcome from the course of action comports with a predicted outcome. If so, a point count can be changed responsive to a further determination that the outcome from the course of action comports with the predicted outcome. Conversely, the point count can be oppositely changed responsive to a further determination that the outcome from the course of action does not comports with the predicted outcome. In any case, when the point count crosses a threshold value, the management of the managed system can be transitioned to an adaptive component.

CDNs and inexpensive and available local (client) storage are combined to increase the efficiency of content delivery and improve the user experience. A large-content element, such as a video file, is stored in segments on one or more servers, allowing clients to make simultaneous requests for segments of the content in parallel. A CDN responds to these requests, optimizing the use of the resources on the CDN nodes. The responses from the CDN are cached during an intermediate process and then delivered, in proper order, to the requesting client. By requesting segments of the content element from multiple locations in parallel rather than requesting a single file containing the entire content element, the burden on the CDN nodes is reduced. Further, since the segments are requested in parallel, cost-of-delivery issues can be factored into the delivery schedule more easily (e.g., bandwidth, time of delivery, whether data is cached), thereby making the delivery process smoother and more economical.

Parallel CDN-based content delivery

A method, system, and computer-readable code for a technique with which files encoded according to the Extensible Markup Language (XML) notation can be marked up to indicate that the content of the file (or some portion thereof) is dynamic in nature and is to be updated automatically to reflect changing information. The proposed technique provides a novel way to specify that a data repository should be accessed as the source of the updates. Techniques are defined for specifying that this data repository access occurs once, and for specifying that it occurs when a set of conditions are satisfied (which may include periodically repeating the data repository access and content update). In one aspect, the data repository is a database; in another aspect, the data repository is a file system. Preferably, the Lightweight Directory Access Protocol (LDAP) is used as an access method when the data repository being accessed is a database storing an LDAP directory.

Objects including Java bytecodes are embedded in a 3270 datastream structured field. The 3270 datastream structured field, including the objects so embedded, are passed between a primary logical unit and a secondary logical unit that communicate with each other over a network using 3270 datastream architecture. An initialization protocol sends a Read Partition (Query) structured field from the primary logical unit to the secondary logical unit, to query whether the secondary logical unit supports Java. The secondary logical unit sends a Query Reply structured field to the primary logical unit in response to receipt of the Read Partition (Query) from the primary logical unit if the secondary logical unit supports Java. In response to receipt of the Query Reply structured field from the secondary logical unit, the 3270 datastream structured field including embedded objects such as Java bytecodes is passed between the primary logical unit and the secondary logical unit. The objects that are embedded in a 3270 datastream structured field may include Java bytecodes, images and audio. Spanning may be used to send objects that exceed structured field length limits. Accordingly, Java and other objects may be integrated with legacy 3270 applications, without requiring the rewriting of legacy applications, and allowing the use of the highly developed 3270 datastream architecture.
