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.
