2. Software Installation

2.1 PatientOS Download

2.1.1 Windows

The PatientOS download is hosted at Sourceforge. Here is the direct URL

Windows Base Install

http://downloads.sourceforge.net/patientos/PatientOS-0.97-Setup.exe

PostgreSQL Database Server Software

http://downloads.sourceforge.net/patientos/postgresql-8.3.7-1-windows.exe

PatientOS Demo Database Contents

http://downloads.sourceforge.net/patientos/demo-0.97-database.zip

http://downloads.sourceforge.net/patientos/demo-0.97-datafiles.zip

Links from the website redirect to sourceforge where it is often difficult to find the download link – look for the text “use this direct link” circled in red below.

2.2 PatientOS Base Installation

2.2.1 Installer

Run the downloaded setup executable PatientOS-0.97-Setup.exe and follow the prompts

a) Installer Language Selection

The first language selection prompt is for the installer language not the PatientOS language.

b) Destination Directory

The destination directory defaults to Program Files. The directory’s disk should reserve at least 750MB space for the installation. A client only install will require less space, the server will grow significantly larger.

The target directory defaults to 0.97. It would recommended to install into a version agnostic directory such as

C:Program FilesPatientOSdemo

or

C:Program FilesPatientOSproduction

However for the rest of the document we will assume the path installed as C:Program FilesPatientOS.97

c) StartàPrograms

By default the software shortcuts will be stored in Start à Programs à PatientOS à 0.97

2.3 PostgreSQL Installation

2.3.1 Installer

Run the downloaded PostgreSQL installer postgresql-8.3.7-1-windows.exe

Accept the default directory to install PatientOS into.

The super user password is critical to remember or write down – it is required to administer the databases.

Use the default port 5432.

Use the default locale.

Press next and finish to install the database software.

3. Database Installation

3.1 Create Database

Before the PatientOS can start properly a database is needed with a username and password the application server can connect to. There also needs to be PatientOS specific contents in the database.

3.1.1 PGAdminIII

The PostgreSQL installation also installs a graphic tool to manager the PostgreSQL databases. Use Start à Programs à PostgreSQL à pgAdmin III to start the tool.

Double click on the single line PostgreSQL Database Server to connect to the database. You will be prompted for the postgres password entered during the PostgreSQL installation.

3.1.2 Create Database Login

Select Login Roles and right click and choose New Login Role.

Enter demopos for the username, password and check off all the privileges.

3.1.3 Create Database

Select Databases and right click and choose New Database.

Enter demopos for the database name and user name.

The encoding will need to match the encoding selected for the installation.

If you have an old installation need to drop the existing database. Stop the application server and execute the following commands.

cd C:progra~1patientos.97serverdatabase

C:progra~1postgresql8.3binpsql -U demopos demopos

drop schema public cascade;

create schema public;

q

3.2 Import PatientOS Database Contents

Load a Demo Database

3.2.1 Import PatientOS Demo Database and Demo Files

The demo database has binary files that are database specific.

Download and unzip the corresponding database files and database contents

http://downloads.sourceforge.net/patientos/demo-0.97-datafiles.zip

Unzip and overlay the files in the data directory

C:progra~1patientos.97serverdata

http://downloads.sourceforge.net/patientos/demo-0.97-database.zip

StartàRunàcmd

cd desktop

C:progra~1postgresql8.3binpsql -U demopos demopos < demo_database.sql

See forum for information on renaming the demo facility to a facility of your choice.

4. System Startup

4.1 Installation

It is assumed that the Windows, Linux or other Installation Guide has been followed and that you have

a) PostgreSQL database installed

b) Import PatientOS database contents

c) Installed the application server software

d) Installed the client software

4.2 Application Server

The application server is JBoss version 4.2.0 GA with the PatientOS specific libraries and configuration files. The application server is required to be running before the client can start. The application server can run on the same server as the client.

4.2.1 Appserver shell script

The windows installation creates a script appserver.bat with a shortcut in

Start à Programs à PatientOS à <version> à Start Application Server (first)

The working directory must be the same as the script. Start the application server.

For a successful installation the last line printed to the shell is Instances Found 0

4.2.2 Service

The application server runs perpetually and in a production setting should be configured as a service. The application server takes 20 seconds to start on a 2 ghz processor. Once started the server typically only needs to be restarted for upgrades.

On windows this is the first time the server has been installed you may need to press Unblock for this dialog:

5. Client Startup

The client can run on the same server as the application server by default. To have the client connect to an application server running on a remote host edit the shell server patientos.bat

On windows right click on the shortcut called Start Client (second) and select Edit. This should open an editor where you can change the script.

On linux

cd <path to directory>/patientos/0.97/client/bin

vi patientos.sh

5.1.1 Client shell script

To connect to a remote host change localhost to the hostname or IP address of the server running the application server.

5.2 Login

Login to the client with

demo/demo to access the system as a privileged physician

admin/admin to access the system as an administrator
