I don't think. Did you try shutting down one node? You can also look at netadmin tutorial to see what FAILOVER means. On Fri, Sep 4, 2009 at 11:58 AM, Bill Davidsonbill...@gmail.com wrote: Mohit Anchlia wrote: Something like this:

This is interesting topic. IANA-failover-expert, but one question comes to my mind. What happens when the first server is recovered? Some cached connections will still point to second server, while newly created connections will go to the first one? Is that acceptable? Regards, Ognjen

I thought the Oracle JDBC driver allowed for all the nodes to be placed into the connect string and the driver was smart enough to detect failover. [So its a configuration exercise on the connection string.] -Tim Ognjen Blagojevic wrote: This is interesting topic. IANA-failover-expert, but

Bill, If you are using Oracle RAC, then why dont you use a RAC JDBC URL that contains both nodes? A DBCP testOnBorrow will ensure only current transactions on a node will fail if one of the nodes goes down, and all new requests for connections from the pool will recover. Bap. Quoting

Tomcat 6.0.20 using DBCP DataSource Java 1.6.0_16 Oracle 10g with RAC. I've got two Oracle RAC nodes, mirroring each other. My current fail-over method if the primary node fails is to shut down the web servers, reconfigure them to use the secondary node and restart the web servers. Not
