Re: Oracle and four node cluster
As for SG vs. RH Cluster Manager - I'll vote for Cluster Manager because it's not restricted to HP hardware and IMHO, has bigger installbase and simplier for configuring. Of course, if you (your company ) have some HPUX SG experience, SG for Linux may be your optimal choice.

Re: Oracle and four node cluster
By the way, there is a tape library on FC. Can one server do backup of all file systems in entire cluster or every server must backup its file systems?

Re: Oracle and four node cluster
On 3rd party server, SGLX does support some 3rd party servers, specifically from IBM and Dell. I know that will not meet the needs of all customers - but then again, no product meets the needs of all customers. Check out the certification matrix on www.hp.com/info/sglx for the list of supported servers.
On backup, I'm no expert but know that most high end backup SW can control backup of a number of servers from one server. What I am not certain of is whether these can "failover" if that is your desire.

Re: Oracle and four node cluster
Still do not know about feature differences.
About backup: In TRU64 which is share everything cluster, every member can access all tape devices, even local tapes on other nodes. If tape is FC, then every node can access it directly. And no special backup software is needed since everything is on cluster file system so everyone can access it dicectly.
Ivan Ferreira knows how it works in TRU64.
Personaly, I would prefer SG, but not sure what would other say.
Any idea how to do backup on FC tape library in linux cluster envirement?

>Still do not know about feature >differences.
I afraid you need read & compare RH Cluster Manager & HP SG docs. IMHO, there no enough people which work with both products.
http://www.redhat.com/solutions/clustersuite/
http://h18026.www1.hp.com/solutions/enterprise/highavailability/linux/serviceguard/index.html
and, BTW, you should understand that as SEP said, you cannot run the same Oracle instance on several nodes simultanuosly without Oracle RAC.

Each cluster node is a separate computer in RH Cluster Manager or HP SG, so in order to backup data from your second node you may use scp (rsync, ...) to copy files to your first node, which has attached tape.

Re: Oracle and four node cluster
I will have to read documentation.
Too bad there are no poeple that worked with both products.
About things what SAP said: of course I understand that same Oracle instance can not run on several nodes simultanuosly without Oracle RAC.
This is not what I mean with active/active. I mean the same Ivan means and also cluster file system ability.
OK, I see there is no way to get TRU cluster functionality.
