PatientView Server Configuration

Patientview runs on tomcat and is written in java. Currently it uses java 8 and runs on tomcat 9. 

RedHat 6 didn't support tomcat 7 so the servers have run using the EPEL release however when an issue occurred with the latest release version we were forced to run a source code version temporarily until the fixed version of tomcat came out. The server is split between two instances of tomcat. One run from source located in /opt/tomcat-importer  (tomcat 7.0.52) which runs the importer tasks and handles the rabbitmq queue of messages and the other which runs the main site and api. There is an nginx front end that routes traffic to the correct local ports. This has now changed to use two copies of tomcat 9.0.xxx located in /opt and /opt/apache-importer  folders and linked to  a standard path as detailed below.

EPEL Setup - this has now been superceded 

Patientview frontend is located in /opt/patientview 

Patientview api and migration is located in /opt/lib/tomcat/webapps 

Current Source configuration

/opt/tomcat  (link to /opt/apache-tomcat-9.0.xxx ) is where the code is stored with the sub folder /opt/tomcat/webapps  containing the api , manager  and migration  code.

/opt/patientview  contains the main frontend  code.

/opt/tomcat-importer  (link to /opt/apache-importer/apache-tomcat-7.0.52 ) with /opt/tomcat-importer/webapps  containing the importer  code
