Managing Caché Licensing
This chapter contains an overview of the Caché license system; it covers the following topics:
• Configuring Caché Licensing
• Updating the License Key
• Determining License Capacity and Usage
• Identifying Users
Important:
Licenses from versions prior to Caché 5.1 do not work with this version of Caché.
Please contact the InterSystems Worldwide Response Center (WRC) for an appropriate
key if you are upgrading from an older version.
InterSystems Terms and Conditions govern how you may use the licensed Caché
software. Occasionally, the implementation may be more lenient. Verify that any
license-related code you write conforms to these terms and conditions.

you must configure one or more Caché license servers to allocate the Caché license units authorized
by the key. All instances sharing a key must be configured to use the same license server or set of
