z/OS-based licensing is available only for IBM® Developer
for z/OS® Enterprise
Edition, and allows a workstation to receive an activation code from the RSE daemon upon connection.
No action is required on the workstation to enable this, but the z/OS host must be configured to
enable provisioning of activation codes, as described in Security definitions.
z/OS-based licensing relies on workstations being able to uniquely identify themselves to the
host. For this purpose, each workstation client generates a unique token upon first connecting to
the host. When a client is cloned to another workstation, the existing unique token must be removed
so that the new client can generate its own unique token. The resetting of the token is described in
Value Unit client licensing considerations.
When the client connects to a host system that is configured for VU licensing, and the user
selects the
MVS Files node in the Remote Systems view, then the Properties
view shows the status of the VU license (Active, Expired, or Not Available) and the registered VU
Offering (for example, IBM APP DLIV FND).
Note: You can see the client-based license type and status
by using the Manage Licenses action in the IBM Developer
for z/OS client or in
Installation Manager, but not the z/OS-based (VU) license status. When the VU license status is
Active, client-based licensing is not used. If the VU license status is
Expired, then client based licensing is used until the client reconnects to
the host system. After the client reconnects to the host, the VU license status is
Active again. As long as users connect to the host at least once every 30
days, the VU license remains active.
