Troubleshooting for problems with the node agent monitoring an IBM® WebSphere® Application Server. This should help address common issues with this component before calling IBM Support and save you time.
Resolving The Problem
1. Are you having problems with Application Servers being unexpectedly restarted by the node agent? This means that you are not sure why the node agent lost contact with the Application Server and restarted it.
- Yes, go to the Troubleshooting Application Server unexpected restart problems section.
- No, continue to question 2.
- Yes, go to the Troubleshooting NodeRestartState problems section.
- No, continue to next section, question 1.
|Troubleshooting Application Server unexpected restart problems|
These are the Troubleshooting questions for problems where your Application Server is unexpectedly restarted.
- Does the node agent SystemOut.log file contain any messages around the time of the Application Server restart, with message IDs ADML0063W and ADML0064I?
- Yes, if you see these messages then most likely the node agent lost contact with the Application Server process and restarted it. Continue with #2.
|Troubleshooting NodeRestartState problems|
These are the Troubleshooting questions for problems where your Application server was not started when the node agent was started.
- When the node agent starts up, does the Application Server fail to start?
- Yes, check the NodeRestartState setting under Servers > Application Servers > server_name. Then, under Server Infrastructure, click Java™ and Process Management > Monitoring Policy.
- If this is set to STOPPED then this behavior is expected. Please change to either PREVIOUS or RUNNING..
- If this is set to PREVIOUS then the Application Server should return to the same state when the node agent was last stopped. If the Application Server was previously running and does not start, please see question 2
- If this is set to RUNNING, then please see question 2
