Like TSO, IMS, and CICS, Netmaster has its own online system of screens that you can access on the mainframe by logging on to the netmaster system. There are a number of options available within Netmaster but the one that allows you to create and maintain your Netmaster Transmissions is in the Data Transfer Services selection menu and is called Maintain Transmission Definitions.
When you go into this option the following screen appears which contains options to maintain a definition, browse a definition, and obtain a list of existing definitions.
--------------- FTS : Transmission Definition Maintenance Menu ---------------- Select Option ===> 1 - Add, Modify, Delete Transmission Definition 2 - Display Definition Detail 3 - List Transmission Definitions X - Exit Name ===> (Required for selections 1 and 2) (Optional start name for selection 3)
The maintain and display screens are fairly similar except for the fact that the display screens do not allow updates to be made to the definition. This allows security to be established that permits some users access to display but not update the transmission definitions as well as ensuring that definitions do not get changed accidentally when you are just wanting to display the information about the transmission.
The transmission definitions are split across two screens. The first screen displays information relating to the sending site and dataset including options to trigger execution of a job on the sending computer after the successful completion of the transmission.
- SYSTEM -------- FTS : Transmission Definition Detail Display --------------- "FROM" dataset details. Press ENTER for "TO" dataset or EXIT to end display. DEFINITION NAME ===> XXXXXXXX DESTINATION ===> XXXXX CLASS ===> A SYSTEM TYPE ===> OS/390 DATASET NAME ===> XXXX.XX.XXXXXXXX or DD NAME ===> DISPOSITION ===> SHR (OLD/SHR) PASSWORD REQ ===> NO EMPTY INPUT ===> N (Y/N) ACKNOWLEDGE TRANSMISSION ===> N (Y/N) AUTO-RESTART ===> Y (Y/N) AUTO-DELETE DEFINITION ===> N (Y/N/C) IF DATASET NOT CATALOGUED: VOLUME SERIAL ===> DEVICE TYPE ===> IF DATASET UNLABELLED: RECORD FORMAT ===> RECORD LENGTH ===> BLOCK SIZE ===> AFTER SUCCESSFUL TRANSMISSION, AT TRANSMITTING END: EXEC COMMAND ===> (Optional) TRANSMIT DEFN ===> (Optional)
The second screen contains information about the receiving site and dataset including options to trigger execution of a job on the receiving computer after the successful completion of the transmission. This is useful for ensuring that the received file gets processed by the receiving system.
- SYSTEM -------- FTS : Transmission Definition Detail Display --------------- "TO" dataset details. Press END KEY to end display. DEFINITION NAME XXXXXXXX DESTINATION XXXXX SYSTEM TYPE OS/390 DATASET NAME ===> XXX.XXXXX.XXXXXXXX(+1) or DD NAME ===> IMAGE-COPY ===> Y (Y/N) DISPOSITION ===> NEW (OLD/SHR/MOD/NEW) PASSWORD REQ ===> NO MUST BE EMPTY ===> N (Y/N) ACKNOWLEDGE RECEIPT ===> N (Y/N) IF IMAGE-COPY=N OUTPUT DCB REQUIREMENTS SPECIFIED: RECORD FORMAT ===> (If these fields are blank RECORD LENGTH ===> DCB attributes of output BLOCK SIZE ===> dataset are not changed.) IF DISP=NEW NEW DATASET DETAILS SPECIFIED: VOLUME SERIAL ===> (Omitted for default volume) DEVICE TYPE ===> SYSDA (Omitted for default type) SPACE UNITS ===> CYLS (CYLS, TRKS or BLKS) PRIMARY QUANTITY ===> 2 SECONDARY QUANTITY ===> 1 DIRECTORY BLOCKS ===> 0 (0 for sequential dataset) AFTER SUCCESSFUL TRANSMISSION, AT RECEIVING END: EXEC COMMAND ===> XXXXXXXX XXX XXXXXX.XXXX.XXXXXXX XXXXXXXX (Optional)
Netmaster transmissions are used for transferring datasets (files) directly between one mainframe and another. No translation of file formats needs to be performed (as would be required when transferring files to a PC or Unix box.
