My system will be having both WebLogic 11g and WebLogic 12c domains running simultaneously on the same box. However, there is traditionally only one NodeManger running for the machine. If I try and connect an 11g domain to a 12c NodeManager it returns errors. If I try and connect from a 12c domain to an 11g NodeManager I get SSL errors.
How do I configure 11g domains to connect to a 12c NodeManager during this transition period?
Starting Weblogic 12c you can start a NodeManager per domain, you should keep your existing NodeManager for 11g and start a new domain specific NodeManager for 12c domain.
