Virtual System Tables

Virtual system tables give 4GL and SQL-92 applications access to the same type of database information that you collect with the Progress monitor (PROMON) utility. Virtual system tables (VSTs) enable an application to examine the status of a database and monitor its performance. With the database broker running, 4GL and SQL-92 applications can call a VST and retrieve the specified information as run-time data.
