How TBEBOOK Works to Export Code Book Information

The following points outline how the TBEBOOK export utility works to export code book information from the z/OS platform:

• The TBEBOOK export utility exports to a sequential file the current instance of a code book and all prior instances of a code book that are still in the BES database. This file can be downloaded by your business partner, emailed to them, or sent by FTP.
• Instances of the code book placed on the 90-day queue are available to support reading of tapes created while those books were current, or to support MOD-ing onto these tape files. These instances of the code book are also placed in the TBEBOOK exported dataset so that an exported code book can support tapes that have been encrypted over periods of time much longer than the REBUILD timeframes.
• TBEBOOK requires that you provide a passkey that is used to encrypt the exported code book. For details on the characters that are allowed in passkeys, see Passkey Rules in this chapter.
• The exported code book produced by the TBEBOOK utility is sent to your B2B partner. In a separate communication, the passkey that was used during the export process is also sent to your partner.
