We are building a QNX application that needs to be very reliable
We will install redundant hardware (see Recomended Hardware Post) - 2
“standard” rackmount PC’s. Worst case we will have a manual switchover (site
manned 24/7) but an automatic switchover would be preferable.
I was wondering if anyone has developped or knows of a simple task to allow
2 PC’s to monitor each other - perhaps using the serial or parallel ports to
allow a standby to take over from an active machine should the active
machine fail. I have had a look at the QNX HAM software and it does not
appear to support redundancy.
I cannot affort to put too much effort into the redundancy aspect, but if
someone knows about a possible solution I would appreciate hearing about it.
