The z/OS software release package, a single binary file with an accompanying README file, is distributed on media.
The z/OS software release is also available as an electronic software download from Teradata. The installation procedure is the same in both instances. Refer to the README file.
Several procedures copy files from the release media. Leave the release media mounted while performing the procedures.
The release media typically contains six files, with a varying number of additional RELFILEs. The following table identifies each release media file by its number, name, and contents. The last column shows which utility you use to access the file.
