Fault-tolerant database available for QNX RTOS

McObject is offering a fault-tolerant version of their database, eXtremeDB, for the QNX Neutrino real-time operating system (RTOS). The eXtremeDB HA is appropriate for process control applications, telecom and networking gear. According to the company, the eXtremeDB High Availability (HA) and eXtremeDB HA Application Framework employ master and standby copies of the database, so the standby copy can step in for the master in case of a failure.

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 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 works with QNX Neutrino RTOS's ability to recover from software faults, even in drivers and other critical programs without rebooting.

The eXtremeDB High Availability and Application Framework release for the QNX Neutrino RTOS is available now for $1,990 a seat.
