OAM : Error while starting servers – Failed to start Service “Cluster” (ServiceState=SERVICE_STOPPED, STATE_JOINING)

Problem :

Error while starting OAM servers in clustered environment. Below error has been logged while starting up the servers.

(thread=Cluster, member=n/a): This member is not authorized to join the cluster. Rejected by Member(Id=1, Timestamp=2017-06-29 12:53:04.123, Address=, MachineId=1901, Location=site:lda,machine:OAMHOST01,process:916, Role=WeblogicServer).> 
(thread=[ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)', member=n/a): Error while starting cluster: java.lang.RuntimeException: Failed to start Service "Cluster" (ServiceState=SERVICE_STOPPED, STATE_JOINING)

All the nodes must have a valid and identical Well Known Address (WKA) list. An empty WKA list will prevent the nodes from forming a cluster.


Set SetWellKnownAddress=false and increase the Version for NGAMConfiguration in DOMAIN_NAME/config/fmwconfig/oam-config.xml file.

Old value

<Setting xmlns="http://www.w3.org/2001/XMLSchema" Name="NGAMConfiguration" Type="htf:map">
<Setting Name="Version" Type="xsd:integer">994</Setting>
<Setting Name="SetWellKnownAddress" Type="htf:map">
<Setting Name="EnableSetting" Type="xsd:boolean">true</Setting>


Updated Value

<Setting xmlns="http://www.w3.org/2001/XMLSchema" Name="NGAMConfiguration" Type="htf:map">
<Setting Name="Version" Type="xsd:integer">995</Setting>
<Setting Name="SetWellKnownAddress" Type="htf:map">
<Setting Name="EnableSetting" Type="xsd:boolean">false</Setting>

Restart OAM managed server.
