Abstract: The present invention provides a computer-implemented method, system, and program product for managing log-in strikes in a geographically distributed computer infrastructure. Specifically, under the present invention, when a strike message is received on a strikeout server pursuant to an incorrect password input during an attempted log-in of a user, the incorrect password is compared to a strike list to determine if it was previously received on the strikeout server during a predetermined period of time. Based on this determination, the incorrect password and will be stored in a list on the strikeout server with a corresponding timestamp. Thereafter, the strike message and the timestamp will be replicated to all other strikeout servers in the infrastructure.

Abstract: A method and system for measuring performance and balancing workload of sites, virtual clusters and servers within the virtual clusters is provided. A monitor measures and computes performance metrics at each level. Servers e.g., LDAP servers, are individually measured for performance, e.g., response time, and based on average response time of servers that are members of a virtual cluster, a virtual cluster performance metric may also be computed. Further, the performance of a site may be profiled based on the virtual cluster metrics and/or server performance metrics. Based at least in part on these performance metrics, a domain oriented request may be resolved and routed based in part on the performance metrics at each level, i.e., site, virtual cluster and server. In this manner, a request may be directed to a destination server to achieve higher performance and efficiencies for the requesting client while at the same time balancing workload among possible servers available to service the request.

Abstract: The present invention provides a change log handler than can accommodate a change log having an entry that includes more than one modification operation or multi-valued attributes. The change log handler typically includes a change parser for parsing change attributes corresponding to the change log that identify changes to the first data source. Such changes can include a plurality of modification operations as reflected in a single entry of the change log. The change log handler also includes a change reflector for applying the changes to a second data source.
