Installation Guide v1.0.0

Overview

The toolkit download is a zip file named asbestos.version.zip. It contains a full installation of Tomcat pre-loaded with the toolkit components. The components are

  • FHIR Toolkit (proxy, test engine, and UI)
  • XDS Toolkit (needed for testing MHD XDSonFHIR option)
  • HAPI FHIR server

While there is one Tomcat Home there are several Tomcat Bases (independent instances of Tomcat). The overall contents look like:

asbestos/
   tomcat/
      bin/
          start.sh            Starts entire tool
          start.bat
          stop.sh             Shuts down entire tool
          stop.bat

          ExternalCache/      External Cache shared between XDS Toolkit and FHIR Toolkit

System Requirements

Java 8 should be installed and accessible through your system shell environment or command prompt. The system should also meet requirements to run Apache Tomcat Server Version 9.0.26. At least one of these environment variables is needed to run this program: JAVA_HOME or JRE_HOME. The following system ports should be available and free to use:

FHIR Toolkit Ports

Port Used by
9705 Tomcat Shutdown port
9709 AJP
9743 TLS (reserved for future use)
9760 HTTP

XDS Toolkit Ports

Port Used by
5000-5015 PIF Listener port range
7297 Proxy Port
9770 HTTP
9773 TLS
9775 Tomcat Shutdown port
9779 AJP

Terms

Term Description
CATALINA_HOME The Tomcat installation directory.
CATALINA_BASE The CATALINA_BASE environment variable specifies location of the root directory of the "active configuration" of Tomcat. See tomcat/RUNNING.txt for more details on CATALINA_BASE. Each type of Toolkit (FHIR, XDS) makes use of a dedicated CATALINA_BASE.
FHIR Toolkit NIST FHIR Toolkit is used for the IHE MHD profiles and FHIR testing.
XDS Toolkit NIST XDS Toolkit is used for the IHE XDS profiles.

Contents

The asbestos_complete1.0.0.zip file contains a Tomcat Application Server bundled with the following Java Web Applications:

  • FHIR Toolkit v1.x.y
  • XDS Toolkit v7.3.+
  • HL7 HAPI v3.7

Of these elements, XDS Toolkit is optional. It is only used to support the XDSonFHIR environment. In the future its installation will be optional.

Installation

Unzip the contents to a directory of your choice. The full path of the directory to which the ZIP file was extracted will be referred to as <installation-directory>.

<installation-directory>

In the references below, you will have to replace with the directory location of the folder where the ZIP file was extracted.

Starting FHIR Toolkit

Starting FHIR Toolkit the easy way

We have installed two custom scripts in tomcat/bin. The scripts will start HAPI FHIR, XDS Toolkit, and FHIR Toolkit (in that order).

On *nix

Script
start.sh to start both the XDSToolkit base and the FhirToolkit base (in that order)
stop.sh to stop both

On Windows 10

Batch file
start.bat To start both the XDSToolkit base and the FhirToolkit base (in that order). Note: start.bat must be typed along with the .bat file extension.
stop.bat To stop both

Launching FHIR Toolkit UI

To launch the UI for FHIR Toolkit, open a Web browser to http://localhost:9760/

Advanced installation options

In the above default configuration, FHIR Toolkit, HAPI, XDS Toolkit and the user's browser are all running on one machine and all references between system components are through localhost. FHIR Toolkit can be installed and configured with all the Tomcat services in different instances of Tomcat on different machines and the UI running through a real hostname.

There are currently two sources for configuration information: the HOW-TO section below and https://github.com/usnistgov/asbestos/wiki/Configuration. These will be combined in the future.

Optional: Running Only the FHIR Toolkit (without HAPI FHIR or XDS Toolkit)

HL7 HAPI FHIR

HAPI FHIR Website

https://hapifhir.io/

The version of the HAPI FHIR that was used to test FHIR Toolkit can be found here

The Default External Cache Location

The default ExternalCache location for all Toolkits is <installation-directory>/tomcat/Toolkits/ExternalCache

HOW-TO

Replace XDS Toolkit with another version

TBD: Replace FHIR Toolkit with another version

TBD: Replace HAPI FHIR with another version

Changing the ExternalCache directory

The External Cache directory is specified by the -DEXTERNAL_CACHE Java System Property in the <installation-directory>/tomcat/Toolkits/FhirToolkit/bin/setenv.sh (or setenv.bat). If an alternate External Cache location is desired, please update the -DEXTERNAL_CACHE Java System Property in the "setenv" batch file/script.

Changing FHIR Toolkit host name

The default host name used by the FhirToolkit is "localhost". This value is reflected in the FhirToolkit Capability Statement and also used by the backend API calls. If you wish to change the host name, please update the following:

  • Update the relevant part of the fhirToolkitBase property in <installation-directory>/tomcat/Toolkits/FhirToolkit/webapps/ROOT/serviceProperties.json
  • Update the relevant part of the fhirToolkitBase property in <installation-directory>/tomcat/Toolkits/FhirToolkit/conf/service.properties

Changing FHIR Toolkit port

The default port used by the FhirToolkit web application is 9760. This value is reflected in the FhirToolkit Capability Statement and also used by the backend API calls. If you wish to change the port, stop the Tomcat instance and please update the following:

  • Update the relevant part of the fhirToolkitBase property in <installation-directory>/tomcat/Toolkits/FhirToolkit/webapps/ROOT/serviceProperties.json
  • Update the relevant part of the fhirToolkitBase property in <installation-directory>/tomcat/Toolkits/FhirToolkit/conf/service.properties
  • Update the relevant part of the <installation-directory>/tomcat/Toolkits/FhirToolkit/conf/server.xml (Other Tomcat related ports such as 9705, 9709, 9743 are also configured in the same server.xml file.)

Restart Tomcat.

Configuration Files

File Description
serviceProperties.json Mainly used by the FHIR Toolkit Web Interface to communicate with the FHIR Toolkit backend API
service.properties FHIR Toolkit service properties. All of the FHIR Toolkit backend process API related URLs (XDS Toolkit, HAPI FHIR) are configured in the following file: <installation-directory>/tomcat/Toolkits/FhirToolkit/conf/service.properties
toolkit.properties XDS Toolkit properties
hapi.properties HAPI FHIR configuration properties
