Websphere: javax.management.InstanceNotFoundException

 

When install the second node in cell, got the following exception wrong port number:

ADMU0001I: Begin federation of node second_NODE with Deployment Manager at

deploymentMgr:8880.

ADMU0027E: An error occurred during federation

WebSphere:process=server1,type=ConfigService,*; rolling back to

original configuration.

ADMU0211I: Error details may be seen in the file:

/…/Profile/logs/addNode.log

ADMU0113E: Program exiting with error:

com.ibm.websphere.management.exception.AdminException:

javax.management.InstanceNotFoundException:

WebSphere:process=server1,type=ConfigService,*, resulting from:

javax.management.InstanceNotFoundException:

WebSphere:process=server1,type=ConfigService,*

Solution:

1. make sure the port number is correct by checking from /……/DeploymentMGRProfile/properties/wsadmin.properties

you should see the following:

com.ibm.ws.scripting.connectionType=SOAP
#com.ibm.ws.scripting.connectionType=RMI

#-------------------------------------------------------------------------
# The port property determines what port is used when attempting
# a connection.
# The default SOAP port for a dmgr or custom profile is 8879
#-------------------------------------------------------------------------
com.ibm.ws.scripting.port=8879

2. make sure both machines (new node and the one has deploymentMgr installed) can be reached, if not add entry to /etc/hosts for both to make sure they can reach each other.
