WebLogic: Node Manager Error

I am unable to start Managed Server with the help of Node manger.

I have Admin Server, 2 Managed Servers on a same machine. SSL is enabled for Admin server and disabled for 2 managed servers. I can start the Managed Servers using ./startManagedWeblogic.sh script. However, I am using DemoTrust keystore for this domain and in NodeManger.properties has following setting:


This .JKS file is configured for some other domain which uses this nodemanager to start its managed server and the works fine. NodeManager.hosts has both the IPs binded.

Here is the Error Message:

[Security:090477]Certificate chain received from xxxxx02 - was not trusted causing SSL handshake failure.. Please ensure that the NodeManager is active on the target machine].]

My question is, Why it is throwing an SSL error, even though SSL port is disabled for both the managed servers?

I may not be understanding, but you are using the DemoTrust keystore on the admin server, yet the CustomIdenty keystore settings are present and uncommented in nodemanager.properties correct?  If this is true this will produce ssl exceptions.  To be very simplistic you may try using CustomIdenty keystore accross all servers.  

If that is not a viable option, you may also follow the steps listed below to run two node managers for two different apps running the same weblogic version on the same server(s).

1. copy ${WL_HOME}/common/nodemanger folder to a folder specific for this new application (ex. ${WL_HOME}/common/{appName}nodemanager) and then copy the startstopNodemanger.sh script, also renaming it specific to the new application (${WL_HOME}/server/bin/${appName}startstopNodeManager.sh).  

2. Once these have been renamed you will need to change the value of NODEMGR_HOME in the new ${appName}startstopNodeManager.sh script to the new directory you created (NODEMGR_HOME="${WL_HOME}/common/${appName}nodemanager")

3. Then edit nodemanager.properties in the new directory and comment out all of the keystore data.  You should only need to specify the values listed below in this file as Demotrust / DemoIdentity  are defaults.

PropertiesVersion=8.1 (or your current version)
ReverseDnsEnabled = true
ListenAddress = (ip or DNS)
ListenPort = (port #) (this must be different than what is being used by the other cluster if both clusters are running on the same machine, this must also be changed in the admin console under the nodemanager tab for each machine.)

Hopefully this helps and did not confuse you.  :)

btw I found this OTN Discussion, which may help.

Sounds like a good solution. I will definitely give it a try!
I have Production Mode Enabled. So, I was wondering if Demotrust / DemoIdentity Keystore work in this case.

Thanks for responding!

No problem, I am glad that worked for you.  I apologize for the rough delivery, I even confused myself when writing those instructions. :)  Good luck with your new cluster.
