Open High Availability Cluster
A year ago Sun announced that it was going to be open sourcing its high availability cluster software. According to this blog, they are now delivering on that promise six months ahead of schedule by releasing two million lines of code. TWO MILLION!!!! thats loads! OHAC isn’t quite the same as Solaris Cluster. Its basically most of the code base, but not all packaged up and is not currently supported by Sun. However, Sun is intending on moving the development work away from the official product and onto the OHAC in the future. This is great news for anyone thinking of developing there own custom agents for their own software, or for anyone who just wants to poke around some enterprise-class cluster software!
