Abstract: A method, system, and computer program product are provided for performance anomaly detection. Velocity data is periodically received from a workload manager for one or more address spaces. An expected velocity value is created for each of the one or more address spaces. A factor of the expected velocity value is compared to a current velocity value from the velocity data. Based on the current velocity value being lower than the factor, a remedial action is generated indicating an anomaly.

Abstract: An apparatus and method to analyze relationships of objects when all objects in combinations are required for the problem resolution to determine which objects to place in a container (cache) to thereby improve database performance and utility. Preferred embodiments are illustrated with respect to attribute caching in a computer database system, where the attributes or objects that need to be cached are not individual attributes, but combinations of attributes where including one object affects all combinations in which it exists. In other preferred embodiments, attribute caching is described where including a combination of objects affects all other combinations that contain one or more of the individual objects in the included combination.

Abstract: A system is presented for performing a directory operation within a distributed directory environment that includes distributed directory servers and a proxy server that acts as an intermediate agent between a client and the distributed directory environment. The proxy server sends requests to directory servers to collect information about group memberships for a user with respect to group entries within each portion of a distributed directory that is supported by each directory server. The proxy server sends the compiled information of group memberships for the user along with any directory operation that the proxy server requests on behalf of the user. A directory server receives the compiled information of group memberships along with a requested directory operation and then performs the requested directory operation with respect to its locally stored portion of the distributed directory information tree and with respect to the received information of group memberships for the user.

Abstract: A system and method for autonomically maintaining group referential integrity across a distributed directory. When a server receives an operation request from a client regarding an entry in the distributed directory, the server sends a request to the particular server containing the entry to be modified that instructs the server to modify the entry, but without performing a referential integrity check. The server then determines whether the request returned successfully. If so, the server sends a request to each server in the network to perform the requested operation on all group references for the entry, but without actually performing the requested operation on the entry itself. If all of these requests return successfully, the server notifies the requesting client that the requested operation has been performed.
