McObject has released eXtremeDB High Availability (HA) and the eXtremeDB HA Application Framework for the QNX Neutrino realtime operating system (RTOS). This fault-tolerant version of McObject's in-memory database system leverages QNX Neutrino's network-distributed message passing to deliver the highest degree of reliability, along with eXtremeDB's unsurpassed performance and ultra-small footprint. Process control applications, telecom and networking gear, and other systems with demanding ""five nines"" (99.999% uptime) reliability requirements comprise a fast-growing segment of embedded software developed on QNX Software Systems' RTOS. These often mission- and life-critical applications are managing greater volumes of more complex data - creating a need for fast, lightweight databases that can meet their reliability demands.
McObject's eXtremeDB HA introduces an innovative, platform-independent High Availability Application Framework architecture based on a rugged, time-cognizant, two-phase commit protocol. Taking advantage of QNX Neutrino's seamless and reliable message passing, McObject's protocol ensures that changes to the master database and identical standby databases succeed or fail together. Deployed atop QNX message passing, the HA Application Framework enables deployment of multiple fully synchronized eXtremeDB databases within the same hardware device or across multiple, widely distributed systems.
eXtremeDB's two-phase commit protocol facilitates instantaneous fail-over, with zero replication-induced latency. This instant database recovery perfectly complements the ability of QNX Neutrino RTOS-based systems to recover intelligently from software faults, even in drivers and other critical programs - without rebooting.
