Greetings,

I am currently entitled to evaluate which solutions can support an
active/passive ("Cold Failover") system based on SuSE Enterprise Linux
9 running Oracle 10G.

I've reviewed couple of products, based on the data sheets and our
requirements, such as:

- HP MC ServiceGuard
- Veritas Cluster Server
- Veritas Storage Filesystem
- Polyserve Matrix Server
- Red Hat Cluster Suite

However, those are just theoretical reviews. No pratical exercises
have been done to assure they work the way we expect them to.

As such, I am looking for your opinion regarding this subject. Who has
put up a system configuration like this? Which solutions were used?
success and insucess cases? your sugestions?

On another SuSE maillinglist, I was told about Oracle RAC and I talked
to our local Oracle DBA. He told me that RAC serves the purpose when
there's 2 oracle instances, each on a different server, both sharing
the same storage. That's not our purpose. We want that if the active
node (server/instance) dies for some reason (network outage, hardware
failure, etc) the other server takes the lead, launches an oracle
instance and mounts the storage.

We are going to use the hardware on the following list to accomplish this:

2x HP BL25p, with 4xOpteron 200 series and 8gb ram. Fibre channel adapter
1x HP StorageWorks EVA 3000 for shared storage.

Hope I was clear enough and I hope there's someone out there who's
been through a similar issue.

Thanks,
Pierre
