You set up both SQL servers. Install SQL and what not. Once those servers are set, you then install CoStandby Server (now named AutoStart)
In Legato, you create a virtual IP address for the two servers to use. This IP address will be the IP address you use in the data source in the CF administration. (assuming you us TCP/IP, in which you must for Legato to work) This IP address will be different from the physical IP address of the machines. When the primary database server crashes, Legato brings the secondary server active using the virtual IP address. Legato manages the active/passive setup. CF will never know if one goes down or the other. It is transparent to CF. I have a 3 second delay in my Legato setup. If my primary server crashes, I give Legato a 3 second wait until it makes the secondary server active. This is so a hiccup in the network does not cause the secondary server to become active unnecessary. For the amount of database transactions we do, this is acceptable to us. I like Legato over Microsoft because with Microsoft, the two servers share the mirrored drive. In Legato, the servers have a separate hard drive that Legato mirrors. http://legato.com/products/autostart_se/index.htm Jacob -----Original Message----- From: Tony [mailto:[EMAIL PROTECTED] Sent: Friday, December 16, 2005 8:41 AM To: CF-Talk Subject: Re: CFMX and Sql Server 2005 (mirrored instances) VIP address? is that a legato thing? so legato sits in front and manages the ACTIVE/PASSIVE setup, and cfmx looks to legato for "WHERE TO LOOK" or something like that? tw On 12/16/05, Jacob <[EMAIL PROTECTED]> wrote: > We have two mirrored SQL 2000 servers (soon to be 2005).
