Licenses

Running the Kx Platform requires 2 license files.

License Descriptions
k4.lic kdb+ License
.delta.lic Kx Platform License

Then Kx Platform runs on kdb+ and so requires a kdb+ license file (k4.lic/kc.lic). For more details on the kdb+ license, see code.kx

The Kx Platform itself is licensed separately via the (.delta.lic) which enables certain features of the Platform.

Both license files can be requested via support@firstderivatives.com

Deploying License files

License files are required in order to deploy and run the Kx Platform. Kdb+ and Platform Licenses are tied to either a hostname (e.g. host.firstderivatives.com) or a domain name (firstderivatives.com). The kdb+ license is typically restricted to a number of CPU cores.

  • Linux license files are prompted for by the installer.
  • Windows license files are manually copied into the config directory (<deploy-dir>/delta-bin/config)
