Hello everyone,
I feel lost here. I hve configured two service groups in a cluster. Siebel server and Siebel Gateway. both of these components require oracle client instance to be running. And the recommended directory structure given by cluster vendor is to install oracle agent of siebel server on /siebel and for gateway on /gateway. where /siebel and /gateway are shared storage. Does it really work? If the gateway service fails over to the node running siebel server, will it be able to connect to database using oracle client present on /gateway ? i.e. 2 oracle client instances running on two different mount points ut accessed through a single node? Is it even a feasible solution? Kindly provide your valuable inputs. Thanks.

What do you mean by 'client instance'? AFAIK the term 'instance' is used in context of server, not client. Nonetheless, you can use multiple Oracle-client-installations on the same computer (different versions either), provided your environment variables ORACLE_HOME, PATH, LIBPATH/LD_LIBRARY_PATH etc are set up accordingly.

Am sorry for not being clear. Yes its "Oracle client installations" on two different mount points. One mount point is used up by one service. My doubt is when both the services are running on the same node, one service connects to database using one mount point and other using the other mount point. Is that feasible? I have setup siebel server and siebel gateway for HA. Now siebel server requires oracle client under /siebel/ora11 and siebel gateway under /gateway/ora11g. This is a recommendation by the vendor. I doubt whether this works when both siebel server and siebel gatway are up on the same machine. This actually means that one gateway authenticates using /gateway/ora11 and iebel server connects to database from /siebel/ora11. I am mixed up whether this configuration works? Your suggestions will be of great help

Then why don't you call Oracle??? Both Oracle and Siebel CRM are commercial, PAY FOR applications. They're not free, and when you pay for them, you get support.

If the vendor is telling you what to do, why don't you ask the vendor for clarification? Those are both different directories, so why wouldn't it? Why would the vendor (who WROTE the software, the installation guides, tested it, and marketed it), specifically tell you to do it wrong????

@TBone,
The case has already been raised for support with oracle. In India, its very slow. I am waiting though.

I still think you aren't talking about clients... I can only repeat: you can have multiple client installations...
For example, I have three Oracle clients installed, in directories /usr/local/OraHome9, /usr/local/OraHome10, /usr/local/OraHome11. Normally, I use the latest, but I could use version 9 with a script like this:
