Oracle7 Server Tuning
Overview
Oracle provides a method for applications to register the name of the application and actions performed by that application with the database. Registering the application allows system administrators and performance tuning specialists to track performance by module. System administrators can also use this information to track resource usage by module. When an application registers with the database, its name and actions are recorded in the V$SESSION and V$SQLAREA views.
Your applications should set the name of the module and name of the action automatically each time a user enters that module. The module name could be the name of a form in an Oracle Forms application, or the name of the code segment in an Oracle Precompilers application. The action name should usually be the name or description of the current transaction within a module.
