Term

Detail

Problem

The management console hung at the loading step for more than 5 mins.

Cause

The loading page is not redirected properly.

Java environment variable is not defined correctly

Troubleshooting

Refresh the page.

Check the tomcat log file. The log should report an issue with the JRE_HOME environment variable.

Solution

Install JRE 8 x64 (from update 171) and set the JRE_HOME system environment variable to the JRE's installation path.

If the loading step hangs for more than 5 minutes, please first try refreshing the page.

There should be an error message involving the JRE_HOME environment, such as in the below screenshot. This error message should occur when the OPSWAT Central Management starts.

In order to fix this error, please install JRE or JDK version 8, from update 171, and set either the JRE_HOME or JAVA_HOME environment variables to the correct installation path. Restart OPSWAT Central Management service for the changes to take effect.
Please refer to the Java configuration guideline for more detail on setting up the environment variables.
