Sybase OpenSwitch can provide near-continuous database access during planned downtime and unplanned outages. OpenSwitch is placed between client connections and two or more Sybase RAPCache servers. During a failover or switchover, OpenSwitch transfers access from the primary RAPCache server to the next available server in the pool.
If you use OpenSwitch as a component of your High Availability configuration, read this section to learn about tasks you perform before you install OpenSwitch.
