Re: Sun HA Monitoring and Oracle 9

Barb,

    This isn't an Oracle limitation. It's a Sun HA limitation. Oracle 9i will run on Sun Solaris HA 2.2, with no problem. We've installed it and built an instance and run it. The problem comes in when you want to HA monitor the database. HA 2.2 won't even run when it gets to the Oracle 9i instance. The problem is so bad that the program just exits as soon as it hits that instance, so it ends up not monitoring anything, not even the 8i instances.

    Our SA called Sun and was told that HA 2.2 only works with Oracle through 8i. If we want to use it with Oracle 9i, then we have to buy HA 3.0 (it's not an upgrade, they consider it a new product). They did say that HA 3.0 will support Oracle 8i and 9i, but nothing before Oracle 8i.  Unfortunately, the changeover means that we would have to do a complete rebuild of the Sun Cluster, which is not possible. We can't have that much downtime (about 1 week). If we get the funding, our plan is to buy 2 more Sun machines, build a 2-node cluster with HA 3.0, migrate the applications to that cluster, then bring 2 of the original Sun machines into that cluster, making it a 4-node cluster again.
