Issue/Introduction

Cannot change the Apache Tomcat® Service to Tomcat9CAOMWebViewer12 for v9.0.31.
Was able to start the service after updating paths in the Apache Tomcat® Daemon. The OM Web Viewer https:// site comes up, but cannot view reports or even logoff. 

Environment

Output Management Web Viewer 12.1
Apache Tomcat®

Resolution

1. Make sure the JAVA_HOME environment variable is set.
2. Make sure the JDK is at 64 bit Java 8 or higher
3. For the Tomcat Service properties, adjust the JavaClassPath and Java Options.
4. Under the Java tab, increase the memory to 4 Gig or more depending on availability.
5. If needed make changes to the Service Name and Description.
6. To put the changes into effect, the Service needed to be Removed, and then it had to be added back.  Service.bat remove; Service.bat install.
7. The final change, the one that restored full functionality, is to update the server.xml file to match the server.xml file from the previous Apache Tomcat® version.
