Defining System Options in Parmlib › Sample Parmlib Members › B2B Code Book Options

B2B Code Book Options

Use the B2B code book options in the B2BCodeBooks section to specify the names of the code books to be defined to the BES database.

The B2B code books named in this section are used in the CodeBook section to specify detailed attributes for the associated code books.

Note: For information about the attributes of each code book, see CodeBook Options.

Each time a tape data set is created using a DFSMS data class, or CA@BES for security protection profiles in your security system, for CA Tape Encryption, and a description containing BES keywords that request a code book, the BES database is searched for this code book. If the code book is found, it is used to randomly generate a new key or to extract a key for data already encrypted using the code book. For new keys, information is written to the tape labels to uniquely identify the instance of the code book used. Instructions on how to reconstruct the key from the code book are also written to the tape.

On the z/OS system, you can read tapes encrypted with code books, or add new data to the last encrypted file on the tape using MOD processing, for the length of time that the specific instance of the code book remains in the BES database. Ordinarily, this time period is up to 90 days after the code book is rebuilt, as specified by the REBUILD code book option.

CodeBook='codebookname'

Assigns a name to a code book to be defined to the BES database. This name also identifies the name of a customizable section for defining the code book attributes. This value must be a section name defined in the same parmlib member. You can have as many CodeBook names as needed to support your non-z/OS business partners. You can define a different code book for each partner or reuse the same code book between two or more partners, as needed.

Limits: 26 alphanumeric characters, plus the special characters: $, #, @.

Note: Any spaces that come before the first non-space character are discarded.

Default: None
