Runtime Connection Load Balancing - ODAC OCI

Post by hdlacerda » Sat 12 Oct 2013 16:06

Hi,

We're planning migrate to Oracle RAC environment and I would like to know if using runtime connection load balancing is supported by ODAC oci, from which version it's supported and if I need to link my app as Oracle documentation.

Oracle docs about FAN: you must link the application to a threads library. This is required because the AQ notifications occur asynchronously, over an implicitly spawned thread.

Hello,

Load Balancing is supported at the level of the Oracle client, and if your client supports this functionality, you can use this feature independently on the used components.
We initialize the library with the OCI_THREADED key, therefore the functionality must work correctly
