Abstract: Method and apparatus for identifying a cause for a response time problem for a transaction in a distributed computing system that includes a central server and a plurality of subsystems. Data is stored at each subsystem relating to sub-transactions of transactions performed by the subsystems. When a problem is discovered in connection with the completion of a particular transaction, each subsystem of the plurality of subsystems that was involved in the particular transaction is identified, and both instance data relating to all of the sub-transactions of the particular transaction stored at each identified subsystem and current hourly aggregate data stored at each identified subsystem is forwarded to the central server. Root-Cause Analysis is then performed using the forwarded instance data and aggregate data to identify the particular subsystem that caused the transaction problem.

Abstract: A directory event system for providing timely event notifications of each data manipulation of a master directory database and for providing timely event notifications of each corresponding data replication to a replicate directory database is disclosed. The directory event system includes an event master server, one or more event service servers, and one or more event client servers. For an event client server having directory clients in electrical communication with the master directory database, the event master server provides an event notification to the event client server in response to a data manipulation of the master directory database by a directory service provider server. The master directory clients can immediately poll the master directory database for the manipulated data upon receipt of an event notification from the event client server.
