Is possible to change the JMS Default Connection Factory (weblogic.jms.ConnectionFactory) in Weblogic?
It doesn't appears on Admin console. Is possible to access it through WLST? I can 't find it on MBean tree (domain an server config).
I want to change some Flow Control settings. I know I can create a new Connection Factory, but I don't want to change my application code uses teh default CF jndi name.
There's no way to change the default connection factory tuning. If you need to tune a CF setting for an app that's using a default CF, then tuning is accomplished using the steps you mentioned: (A) configuring a custom connection factory, and (B) changing apps that need specialized tuning to refer to the JNDI name of the custom connection factory.
It's often helpful to use "Foreign JMS" to enable changing an app's CF without changing the app. See http://docs.oracle.com/cd/E21764_01/web.1111/e13727/interop.htm#i1009775
