NOTE

·         Unzip the contents of the dependency package file provided by Panopticon into the TOMCAT_HOME/lib folder to be able to run Altair Panopticon software on JRE 8 and Open JDK 8.

·         Please refer to Java documentation about setting up the JAVA_HOME environment variable in your system.

   NOTE

When running on Windows instead of Linux, it is recommended to use the zip distribution of Apache Tomcat for Windows rather than the Windows Service Installer. This is because the zip distribution will let you run Apache Tomcat without any dependency on the Windows service manager, and management of the Apache Tomcat server will conform more with how it is done on Linux.

   NOTE

Starting with Tomcat 9, Debian Linux implements a security policy which puts a harder default restriction on which folders a Tomcat 9 web application can write to.

The change is described in full detail here:

https://salsa.debian.org/java-team/tomcat9/-/commit/3ca5cbdc2f970470341926354f210dff032fc5f3

Quoting from the release notes:

·         Tomcat is sandboxed by systemd and only has write access to the following directories:

·         If write access to other directories is required, override the service settings. This is done by creating an override.conf file in /etc/systemd/system/tomcat9.service.d/ containing:

[Service]

ReadWritePaths=/path/to/the/directory/

Ensure to restart the service afterward with:

o     systemctl daemon-reload

o     systemctl restart tomcat9

   NOTE

·         Panopticon Real Time requires administrative privileges during installation. Administrative privileges are not required after installation is complete.

·         Panopticon Real Time does not support Tomcat 7.x, Tomcat 8.0.x, or Tomcat 8.5.x.
