Running Weblogic Server when connected to VPN

As part of my development work, I tried to run my Weblogic Server when I am connected to VPN network.

The weblogic server failed with error saying:

(thread=Cluster, member=n/a): Delaying formation of a new cluster; unicast networking appears to be inoperable on interface as this process isn't receiving even its own transmissions; consider forcing IPv4 via -Djava.net.preferIPv4Stack=true>

We can resolve this error by setting a JAVA_OPTIONS in setDomainEnv.cmd file located in \bin folder. The setting is as follows:

set JAVA_OPTIONS=%JAVA_OPTIONS% -Djava.net.preferIPv4Stack=true

Now the weblogic server starts without any issue when connected to VPN Network.

Happy Learning!!
