System Requirements

This page discusses the requirements for running Stardog.


Stardog 9+ is tested on Java version 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 11 can be downloaded from Oracle, which requires creating an account. Alternatively you can use an OpenJDK implementation from Adoptium or Microsoft.

Verified Operating Systems

Stardog is verified to run on:

  • Ubuntu 20.04 and 22.04
  • Debian 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
