NullPointerException in the nodeagent SystemOut.log file during nodeagent startup
 Technote (troubleshooting)
 
Problem(Abstract)
The Node Agent does not start the application servers if it cannot perform the synchronization successfully when Startup auto-synchronization of the nodeagent is enabled. A NullPointerException is seen in the nodeagent SystemOut.log file during nodeagent startup.
 
Symptom
If the Node restart state in the server monitoring policy is set to running and the Startup Synchronization is set to true in the nodeagent System Administration, the following exception is seen in the nodeagent SystemOut.log file during nodeagent startup. The nodeagent also fails to start the server.

12/14/04 11:43:29:253 EST] 28680f95 NodeSync E ADMS0012E: Unable to create administrative client connection: com.ibm.websphere.management.exception.AdminException: Admin client connection to deployment manager is unavailable

Caused by: java.lang.NullPointerException

Refer to the attached Nodeagent SystemOut.log file.

 
Resolving the problem
The Node Agent does not start the application servers if it cannot perform the synchronization successfully when Startup auto-synchronization of nodeagent is enabled. This behavior is working as designed.

To avoid the exception in the nodeagent SystemOut.log file:
  • Uncheck the Startup Synchronization in System Administration > Node Agents > node_agent_name > File Synchronization Service.

    or
  • Change the Node restart state to stopped in Servers > Application Servers > server_name > Process Definition > process type > Monitoring Policy.
