摘要： Session state affinity is maintained in a workload balancing system that includes a hypertext transfer protocol (HTTP) routing server and a plurality of application servers. The application servers maintain backup session state information for a first session to a first server of the plurality of application servers at fewer than all of the plurality of application servers, detect the unavailability of the first application server at an application server of the plurality of application servers other than the first application and determine a second server that continues the first session. An identification of the second server and the first session is sent from an application server of the plurality of application servers to a HTTP routing server responsive to detecting the unavailability of the first server. The identification of the second server and the first session is received at the HTTP routing server and communications associated with the first session are routed from the HTTP routing server to the second server responsive to receiving the identification of the second server so that backup session state information maintained at the second server is used to continue the first session from the first server at the second server.

摘要： A computer system retrieves from data repositories change information indicating changes to entries. Each data repository is associated with a corresponding interface and at least two data repositories are associated with different interfaces, and at least one data repository lacks tracking of changes to entries stored therein. The change information retrieved from the data repository is stored within a storage unit. The stored information includes identification of each repository entry change without storage of the changed entry. Requests are processed to provide change information for entries within the data repositories, wherein processing the change information request for one of the entries includes retrieving from the storage unit the identification of the repository entry change for the one of the entries. Embodiments of the present invention further include a method and computer program product for tracking changes within data repositories in substantially the same manner described above.

摘要： A mechanism is provided for managing the life cycle of software products across multiple platforms. A software product framework is provided for integrating access to information and installation support regarding at least two different software products on at least two different operating system platforms. A first client device is registered for a first version of a software product and a second client device is registered for a second version of the software product of the at least two different software products, where the first version and the second version are not a same version. Responsive to receiving a third version of the software product, the first version is automatically updated to the third version of the software product on the first client device, while the second version is not automatically updated to the third version of the software product on the second client device.

摘要： A migration set list generator specifies a physical topology of a deployed software solution, wherein the software solution comprises software components and data associated with the software components integrated into a single entity. The migration set list generator specifies at least one solution change to the deployed software solution to meet at least one business requirement and specifies at least one migration strategy for migrating the deployed software solution. The migration set list generator generates migration tasks for making the at least one solution change to the deployed software solution specified in the physical topology based on the at least one migration strategy and generates a recommended physical topology yielded for the software solution if the physical topology is updated according to the migration tasks.

摘要： An Intelligent Caching Tool collects reliability statistics for an application server to build a Hidden Markov Model. Using the Hidden Markov Model, the Intelligent Caching Tool calculates a reliability index for the application server. After setting a user defined reliability threshold, the Intelligent Caching Tool caches all client requests and the status of the application server's response when the reliability index is below the reliability threshold.
