1High Availability
• Ingres directly supports Active/Passive failover on Solaris and
Linux
• Separately installed option
• All Ingres file systems must be on a shared disk device, such
as a SAN
• Two configuration options
• Single Node
• Ingres attempts restart on the failed node
• Dual Node
• Passive Node attempts restart when active node fails
• Starting and stopping must be done using operating system
interfaces

2Clustering
• Active/Active clustering available on OpenVMS for the HP (Dec)
Alpha systems only
• Itanium chip support coming soon
• Built on proprietary technologies with OpenVMS
• Distributed Lock Manager is the key component. This is what allows
multiple systems / Ingres installations to access the same physical
database.
• Overhead is generally high (~20%)
• Can provide very high service levels
