QUESTION 101
A critical error is occuring on a production node causing the JVM logs to rapidly fill up. Which resolution should the WebSphere administrator take as the first step for troubleshooting?

1. The logs are self-managing and can roll over based on time ro file size, so simply opening the logs with a text editor will ensure that new log files are created.
2. Removing the application server from the network, either administratively or physically, is necessary to stop the JVM processing.
3. Stopping the JVM process from the command line, removing the application administratively thru the console and restarting the JVM will allow processing to continue on other applications.
4. The administrator should remove the failing application server from user requests, thereby stabilizing the application server so that troubleshooting can begin.
