Adaptive Server stores the audit trail in system tables, named sysaudits_01 through sysaudits_08. For example, if you have two audit tables, they are named sysaudits_01 and sysaudits_02. At any given time, only one of the audit tables is current. Adaptive Server writes all audit data to the current audit table. A System Security Officer can use sp_configure to set or change which audit table is current.
When you configure Adaptive Server for auditing, you determine the number of audit tables for your installation. You can specify up to eight system tables (sysaudits_01 through sysaudits_08). Plan to use at least two or three system tables for the audit trail and to put each system table on its own device, separate from the master device. If you do this, you can use a threshold procedure that archives the current audit table automatically, before it fills up and switches to a new, empty table for subsequent audit records.
