GeSi³ – system requirements



  • 64-bit operating system
  • Windows, Mac OS or Linux
  • 4 GB RAM
  • SSD hard disc with 2 GB free capacity

Server (network installation)

  • 64-bit operating system
  • Windows, Mac OS or Linux
  • 16 GB RAM
  • Processor with at least 4 cores
  • SSD hard drive (with min. 10 GB free capacity)

Program (GESI3.EXE)

  • RAM up to 750 MB by default
  • 600 MB hard disk capacity (for installation, without database)
  • We recommend the use of an SSD hard disk.
  • We recommend that the upper RAM limit is increased to 1024 MB (Tools / Settings / Memory usage).


  • 300 MB (directly after installation)
  • 2 GB as the first target size
    • a significant factor are annexes to hazardous substances or external components
    • as well as annexes (mostly photos) to risk assessments
    • another important factor is versioning
  • 10 GB should therefore be available if a lot of annexes are used
  • The size of the database is not influenced by whether a single-user or network database is used.

Database server (network installation)

  • RAM requirement at least 1 GB (for good performance, 2 GB should be made available)
  • Installation requirement on the hard disk approx. 200 MB
  • GeSi³ uses the Apache Derby SQL database
  • for Windows installations, GeSi³ includes the required DB server


  • Wired company network
  • Gigabit LAN
  • WLAN is frequently too slow
