Free High-Availability Solutions For Solaris?

prwood asks: "Our company is looking into high availability solutions for our Sparc-based servers running Solaris. Primarily this would be used on our Oracle Database servers, but presumably we'd like to expand this to frontend servers. We've looked at Veritas, as well as Sun and Oracle's HA solutions, but we're not wanting to lay out that much money this year. We also have some quick and dirty in-house scripts and such to perform certain tasks, but we're looking for something a bit more robust. So the question is: Are there any free or low cost solutions for getting HA on Solaris? I know there is some good stuff for Linux, but it seems to depend in part on patches to the Linux kernel, and switching to Linux isn't an option for us at this point. Note that we're not looking for load balancing, but rather failover solutions. Suggestions?"
