SET_AUDIT_TIME

Sets the time that Vertica performs automatic database size audit to determine if the size of the database is compliant with the raw data allowance in your Vertica license. Use this function if the audits are currently scheduled to occur during your database's peak activity time. This is normally not a concern, since the automatic audit has little impact on database performance.

Audits are scheduled by the preceding audit, so changing the audit time does not affect the next scheduled audit. For example, if your next audit is scheduled to take place at 11:59PM and you use SET_AUDIT_TIME to change the audit schedule 3AM, the previously scheduled 11:59PM audit still runs. As that audit finishes, it schedules the next audit to occur at 3AM.

Vertica always performs the next scheduled audit even where you have changed the audit time using SET_AUDIT_TIME and then triggered an automatic audit by issuing the statement, SELECT AUDIT_LICENSE_SIZE. Only after the next scheduled audit does Vertica begin auditing at the new time you set using SET_AUDIT_TIME. Thereafter, Vertica audits at the new time.
