Abstract

A multi-tier attribute tracking mechanism identifies end user credentials and other client information and attributes and assigns them to database requests in an application server architecture. Disclosed configurations identify the processing unit, or thread, assigned by the operating system to service the incoming request from the user at the application tier. A matching of users to threads allows successive thread activity to be mapped back to the initiating user. Conventional interception of database access attempts at the application level (“server taps,” or staps) identified only the database user (the account in the database) and associated connection as the responsible user. By intercepting, or “tapping” the access request at the operating system level (using kernel taps, or “ktaps”), the mechanism matches which application requests map to which database requests. With this matching, the database requests can be tagged with the user credentials which are known through the application request.
