When event logging is enabled, you can manage its functions in the following ways:
Use the sp_addmessage or sp_altermessage to control whether a specific user-defined message is logged in the Adaptive Server error log.
For the complete syntax for sp_addmessage and sp_altermessage, see the Reference Manual.
Use configuration parameters to specify whether auditing events are logged. Auditing events pertain to a user’s success, log audit logon success, or failure, log audit logon failure, in logging in to Adaptive Server.
