Hi,
I only got one response on this, from Spider.Boardman. Although he was
addressing a slightly different issue, his code suggested some
clarifications in my thinking. In any event, we will not use auditlogtrim.
Instead, we will be rolling over the audit log file weekly and deleting logs
older than several weeks, relying on our backups to restore those older logs
when needed.
