When you execute a BEGIN LOGGING statement, it creates logging rules which it stores in the DBC.AccLogRuleTbl table. Then for each session, Vantage looks in the DBC.AccLogRuleTbl to determine which privilege checks must generate log entries for a specified database user, action, or object.
Before enabling logging, you must do the following to create the DBC.AccLogRule table.
- Run the DIPACC script to create the special security DBC.AccLogRule macro, which populates the DBC.AccLogrule table with logging information. The DBC.AccLogRule macro may already exist as a result of Vantage setup.
- Run the tpareset utility to initialize the macro.
