[WebLogic] Changing hostname, IP for Weblogic 11g

http://romilbhagat.blogspot.kr/2010/06/changing-hostnameip-for-weblogic-11g.html


There are two ways to solve it.

1. Disable Flags - Jugaad way ;)
   Put the following flags at the right places.
   Node Manager: -Dweblogic.nodemanager.sslHostNameVerificationEnabled=false
   Admin Server: -Dweblogic.security.SSL.ignoreHostnameVerification=true

2. Recreate the Certificates - The recommended way.
   Node manager by default uses the WebLogic demo identity keystore. The keystore is generated at install time using the CertGen utility. The generated private key uses the common name (cn) resolved by Java.

   2.1 Set the PATH
       $> . $WL_HOME/server/bin/setWLSEnv.sh

   2.2 Backup DemoIdentity.jks under $WL_HOME/server/lib

   2.3 Generate the private key.
       ###$> java utils.CertGen -cn -keyfilepass DemoIdentityPassPhrase -certfile newcert -keyfile newkey
       $> java utils.CertGen -cn -keyfilepass DemoIdentityPassPhrase -certfile newcert -keyfile newkey

   2.4 Import the key generated above to the keystore.
       $> java utils.ImportPrivateKey -keystore DemoIdentity.jks -storepass DemoIdentityKeyStorePassPhrase -keyfile newkey.pem -keyfilepass DemoIdentityPassPhrase -certfile newcert.pem -alias demoidentity

   2.5 Copy DemoIdentity.jks to $WL_HOME/server/lib

   2.6 Restart your nodemanager.
