License keys and the Application Developer Controlled Distribution (ADCD)

z/OS® 1.13 ADCD and earlier distributions can be installed without access to an activated . All volumes are supplied as files in compressed (.gzip) format, and the gunzip command makes them usable by ZD&T.

For software-based entitlement, beginning with the z/OS 2.1 ADCD for Rational® Development and Test Environment for z Systems®, an activated is required to install the system resident volumes of the z/OS ADCD. The Z1091_ADCD_install command is used to install these system resident volumes. This command requires access to an activated with connectivity to the instance that does the installation. The same activated that entitles the user to run ZD&T also entitles the user to install a z/OS ADCD.

For instructions on installing the z/OS ADCD, see Installing May 2017 Edition z/OS 2.2 ADCD for ZD&T
