If installation fails, you can run some debugging tools to help determine what is wrong.
You can run the installation program in debugging mode for Windows, HP-UX, and Solaris installations.
The Linux installation program does not have a debugging mode, but the program creates the imanager_install.log and iManagerConfigWizard.log during the install for informational and troubleshooting purposes. These are located in /var/log. The imanager_install.log contains informational/error messages logged during the general install. The iManagerconfigWizard.log contains information/error messages logged during the configuration of iManager.
On all platforms, you can run the iManager servlet in debugging mode. Add ?DEBUG=LOG_LOW to the end of your iManager URL. For example:
https://<ip_address>/nps/servlet/configure?DEBUG=LOG_LOW
Replace <ip_address> with the IP address of your server. This command generates debug information in your Tomcat log files.
