System Requirements

This page discusses the requirements for running Stardog.


Stardog 7.3+ is tested on Java versions 8 and 11, and requires sun.misc.Unsafe. Note that Stardog does not run on any other versions of Java.

To check your version of Java, run the following command from the CLI:

$ java -version

Java 8 and 11 can be downloaded from Oracle, which requires creating an account. Alternatively you can use a version from OpenJDK.

Verified Operating Systems

Stardog is verified to run on:

  • Ubuntu 16.04, 18.04, and 20.04
  • Debian 9 and 10
  • RHEL 7
  • CentOS 7
  • Amazon Linux 2
  • Microsoft Windows Server 2019 (not recommended for production)
  • Recent versions of OSX (not recommended for production)

Disk Storage

Stardog runs best on local / block storage devices. Network based disk storage is not recommended, including NFS, SMB, and EFS based storage systems.

If you must use network based disk, please set the following property within file in your $STARDOG_HOME directory:

storage.envoptions.use_mmap_writes = false
