Abstract: An instrumentation system for a database. A database management system contains instrumentation code which monitors behavior of the system, and stores parameters indicative of the behavior. Those stored parameters are copied into a second database, which is organized according to the same schema as the database itself. Both databases are searchable using the same query language, so that a system administrator can locate (1) data within the database and (2) diagnostic information about the system using a single search tool.

Abstract: One or more computing systems, such as a database server, a web server, or a client computer, delivers information from a database to a user after receiving an instruction from the user to retrieve the information from the database. The computer retrieves the requested information from the database and applies formatting instructions to text extracted from the requested data. In general, the instructions include terms taken from a selected formatting language, such as HTML or XML. Applying the formatting instructions often involves inserting markup-language tags within the text. The computer then displays the text in a format prescribed by the formatting instructions.
