Hello Experts,
We have recently decided to move our standalone server to Oracle 10g 2 node RAC for which the preparations on the test environment have been initiated, so far oracle 10g DB have been setup on the 2 nodes with failover settings. Now my primary concern is to check on options for application servers failover settings, i would like to know if application server needs to be clustered. If so, is there a separate software for this clustering ? or do i have to install application server 10g software on each node separately and just specify DB servers details in TNS for the application server and failover is totally dependent on the DB RAC configuration. All i want to determine is how application can be safely failed over to the next available node with no downtime or loss of transactions/data. Here is a brief summary of setup:
Node 1 - Win 2003 R2 Enterprise Edition, Oracle 10g RAC database (10.2.0.3.0)
Node 2 - Win 2003 R2 Enterprise Edition, Oracle 10g RAC database (10.2.0.3.0)
Could you also answer to following :
a) How should i replicate/keep in sync my application data (a folder containing regularly changed forms/reports) on windows to node 2
Thank you
Ali

Ali, remember that no-one gets paid for helping you.
Thank you for explaining that your question is nothing to do with clustering Application Server (that was a waste of my time, wasn't it?)
What you are actually asking is whether Forms can do TAF. It can't. All is explained in MOS article 243303.1.

Dear Experts,
Could you provide me with some ideas on how to achieve availability, following is what i have :
1) 2 servers with WIN 2003 SP2 installed
2) DB server 10g R2
3) Middleware - Oracle Application Server 10g R2
4) Customised forms Application
5) JDBC thin client Application (self service)
I have managed to succesfully test failover on the DB level. But iam unable to get a clear picture of how to implement availability concept on the middleware, the forms application and JDBC thin client application level (Idea here is to avoid any downtimes, i.e in case one server fails for any reasons the service should automatically failover to the next available node with no data / transaction loss )
Thanks for your suggestions and support.
Regards
Ali
