One of the trainee from our previous batch encountered issue while starting OAM Managed server (oam_server1) from WebLogic Administration Console (/console). When a server is started using Console, a utility called Node Manager is used in the background. Make sure that Node Manager is running and Machine is associated with Managed Server
If you see node manager is fine and still startup fails then check the Managed Server log file located at $DOMAIN_HOME/ servers/ [oam_server1]/ logs and in our case, it was showing below error messages:
Caused By: com.bea.common.engine.ServiceInitializationException: com.bea.common.engine.SecurityServiceRuntimeException: [Security:097533]Security Provider service class name for IAMSuiteAgent is not specified.

In the nodemanager.properties file (configuration file that is used to start node manager), the value of the flag StartScriptEnabled was set to false (by default) because of which the parameters that are provided in startWeblogic.sh was not provided to JVM and therefore, resulting in the error as specified above.
1. Stop Node Manager: Exit from the terminal in which node manager started.
Note: there is no script to stop Node Manager so just kill the process
2. Run setNMProps.sh script located under $MW_HOME/oracle_common/common/bin
./setNMProps.sh (This will enable the StartScriptEnabled flag in nodemanager.properties)
You should get the output as: “Appending required nodemanager.properties”
3. Start Node manager ./startNodeManager located under $WL_HOME/server/bin
4. Start Managed Server using Administration Console. It should be RUNNING now.
