You can run the IGEL UMS with Windows and Linux 64-bit systems (x86_64). For details on the supported operating systems, see Supported Environment 5.09.100.

Your hardware and software must meet the following minimum requirements:

UMS Complete Installation

  • At least 4 GB of RAM (6 GB recommended)
  • At least 1 GB of free disk space (plus database system)

Individual Console Installation

  • At least 1.5 GB of RAM (2 GB recommended)
  • At least 250 MB of free disk space


    Under Linux, an X11 system is required. It is required by the UMS Administrator application which can only be launched on the same machine as the UMS Server.

    As an alternative to a local console installation, you can execute the UMS Console as a Java Web Start application too. The console does not need to be installed here. If necessary, it can be downloaded from the UMS Server and executed. Further information can be found under UMS Console via Java Web Start.

    Do not install the UMS Server on a domain controller system!
    Manually modifying the Java runtime environment on the UMS Server is not recommended.
    Running additional Apache Tomcat web servers together with the UMS Server is likewise not recommended.


For details on the supported database systems, please see Supported Environment 5.09.100. Details of the requirements when installing and operating the database can be found in the documentation for the particular DBMS.


The UMS Server and Load Balancer for High Availability (HA) must be in the same IP network. NAT or proxies must not be between the UMS Server and Load Balancer because they can influence communication between the components.


The embedded database cannot be used for an HA network. You can use the embedded database for a dedicated test installation with only a single server for the UMS Server and Load Balancer.
