You may want to run multiple OpenVPMS systems hosted in the one server, either for test and production systems, or in cases where multiple practices share the same server.

Note that if you are running multiple systems, it is important that you do not get confused about which system you are using.  You can use a different screen colour for each system (see here for how to do this). You should also use different user login names and passwords (so as to prevent an unthinking person signing in to the wrong system). You should also set different database user names and passwords for each system.

One way to run multiple systems is of course to run each in its own virtual machine with these hosted on the one piece of hardware.

However, you can also host multiple systems on the one server.  (Note however that if you use the ESCI facility, then you cannot host multiple systems on the one server.) The way to set this up is as follows:

1. install the first system as per the instructions in the readme.txt file.

2. for the next OpenVPMS system, install the OpenVPMS software in its own folder/directory, now referred to as <OPENVPMS_HOME_X>

3. the database access is defined in the file <OPENVPMS_HOME_X>/conf/, specifically the three lines


Hence for this OpenVPMS system we need to change the database name in the first line from openvpms to say openvpmsX. The user name and password should be changed to say openvpmsU and openvpmsP to decrease the likelihood of you getting confused and doing database operations on the wrong database.

To create the database, we need to edit the file <OPENVPMS_HOME_X>/db/create.sql so it reads as follows:

# Script to create the openvpmsX database, and add a single user 'openvpms',
# with all privileges


GRANT ALL PRIVILEGES ON openvpmsX.* TO 'openvpmsU'@'localhost'

GRANT ALL PRIVILEGES ON openvpmsX.* TO 'openvpmsU'@'%'


where "openvmsX" is the name of the new database, "openvpmsU" the user name, and "openvpmsP" the password. You can now create the database as per the readme.txt, ie do

  > cd <OPENVPMS_HOME_X>/db
  > mysql -u admin -p < createdb.sql

You can now populate the database as per the readme.txt steps, or you can simply dump the contents of the base openvpms database, and then restore this into the new openvpmsX database.

4. Finally we need to set up the Tomcat application.  The easiest way to do this is to first copy the <TOMCAT_HOME>/webapps/openvpms directory to <TOMCAT_HOME>/webapps/openvpmsX.  You then need to edit two files as follows:
  a) in  <TOMCAT_HOME>/webapps/openvpmsX/WEB-INF/web.xml, the webAppRootKey value needs to be set to "openvpmsX" as per the following

    <!-- Needed by spring if you want to deploy app more than once as different name. Change value
      -  to something unique -->

  b) edit <TOMCAT_HOME>/webapps/openvpmsX/WEB-INF/classes/ so it matches <OPENVPMS_HOME_X>/conf/ - see step 3 above.

Now restart Tomcat and you can then access the new system at http://localhost:8080/openvpmsX/app


5. Repeat steps 2-4 for each addition system that you require.
