@Zote: The "mirroring mode" you choose determines how aggressively SQL Anywhere will behave during the commit: guarantee that the commit is performed on the mirror before responding to the client, or don't bother waiting for an acknowledgment, or [something even sloppier]. I've never met anyone who's used anything other than Door Number One, called "synchronous". See "Choosing a database mirroring mode" in the Help. |
