OpenVPMS can be installed on either a unix system (most commonly a Ubuntu* server), or a Windows system.  For Windows, for small practices you can install on a desktop or laptop running Windows 7, 8 or 10; for larger practices it may be better to use a Windows Server operating system.

*NOTE: OpenVPMS requires MySQL 5.5, which is included in Ubuntu 14.04. Later releases include MySQL 5.6 or MySQL 5.7 which are only supported via configuration changes.

32 or 64 bit version? Both Java and MySQL are available in 32 and 64 bit versions. For larger systems (where you will want to run MySQL and Tomcat with large memory allocations) you should use the 64 bit versions. Otherwise the 32 bit versions are adequate.

Server Software

On Windows, the MySQL installer may require that the Microsoft .Net Framework 4 be installed. This is available from:

NOTE: if you are upgrading from an earlier MySQL release, see the relevant MySQL manual for migrating the MySQL data e.g.:


  • should be on the same host as Tomcat
  • should accept connections on port 3306
  • include the following lines in my.ini
    character-set-server = utf8
  • Minimum Innodb buffer size set to 512M.  

NOTE: If character-set-server is not set to utf8, some characters may not be stored correctly. E.g, μ may be replaced with ?

    This may be included in the MySQL server installation.
