We're running RHEL6.2 and RHEL6.4 on our zlinux servers under z/VM 6.2 and so far have been handling HA by just clustering servers--yeah, any transaction in process to a server that's gone down would be whacked in mid-air, but anything new would route to the "cluster-buddy" that was still up. That's not true high-availability, though, and won't work for all our potential applications. Of course, we're looking at SSI which will help out for planned outages, but we'd also like to be able to do something in the case of a server-crash (i.e. have some sort of heartbeat-monitor that could pop up/activate an application on a different server if it noticed something was down). We'll be investigating Tivoli Systems Automation for Multiplatform, and the Sine Nomine HAO (High Availability Option), plus I intend to see if the RHEL HA add-on is compatible with zSeries, but I'm wondering if there's any other good products to explore (as well as anyone's experiences with the above products). We did a cursory look at LinuxHA, but unfortunately our management is not keen on using freeware, even though price will definitely be a consideration in whatever we decide on.
Any comments from those in the field actually exploiting HA for zSeries at their shops? Thanks!
