McObject's in-memory, high-availability (HA) database has been certified for a MontaVista Linux distribution aimed at telecommunications equipment. eXtremeDB High Availability (HA) for Carrier Grade Edition (CGE) comes with a versatile master/slave communications framework said to be unique among embedded databases. It targets fault-tolerant telecom and networking equipment.

MontaVista Linux CGE is a commercial Linux distribution enhanced with open source real-time, high availability, and high reliability features. CGE officially supports several embedded databases, including Sleepycat's Berkeley DB, certified in July, and MySQL, validated in August.

McObject says eXtremeDB is the only embedded database with built-in infrastructure for communication between master and replica databases. Communication is handled through an “Application Framework” supplied as source code, along with prototype applications for communication using TCP/IP, UDP/IP, and Named Pipes.

eXtremeDB HA can replicate over a number of network transport protocols

McObject claims that eXtremeDB HA's Application Framework mitigates development risk in “one of the most complicated areas of HA database integration.” eXtremeDB HA has a proven track record of reliability in networking and telecom gear, it says, along with a tiny footprint, and “blazing” fast in-memory performance.

“Creating the entire infrastructure to ensure real-time updates and rapid failover between database instances in a high availability environment can be daunting, even for experienced database programmers,” said McObject President Steve Graves said.

Additional details about eXtremDB HA are available online.
