PC/Transfer
PC/Transfer is a PC-Host File Transfer System that allows data to be transferred between any PC that is running TCP/IP for VSE, a 3270 Emulator, and a host computer running CICS or Entree.
Conversion Info
Types of data that can be transferred to and from the PC:
• BIM-EDIT members
• VSE Librarian (LIBR) members
• POWER jobs and reports in the RDR, PUN, or LST queues
• VSAM datasets
• VSAM-Managed-SAM datasets
• SAM datasets
• BIM-EPIC managed SAM datasets
• CICS Transient Data (uploads to CICS only)
• CICS Temporary Storage Queues
• Files contained in the VSE Host Transfer File (IND$)
• ICCF members (download to PC support only)
• Transfers are normally initiated and controlled by the PC. In this mode, the host side acts as a server, responding to the requests from the PC.
• The Host Initiated Automatic File Transfer feature (HOSTAFT) of PC/Transfer allows transfers to be initiated by the host, via a batch job stream, or a CICS application program.
• The host side of PC/Transfer can either run under CICS or Entree. Entree is a VTAM/TCPIP application platform available separately from CSI.
• The PC-to-host connection can be LU2 or TCP/IP.
• An on-line transaction (FTRM) is provided by PC/Transfer. This is used to define to the host the types of transfers that are to be supported, and which PC users are allowed to perform them.
• A ‘Transfer Activity Log’ can be maintained by the host side of PC/Transfer in a VSAM RRDS dataset. An on-line transaction (FTRL) is provided for viewing this log. A Transfer Log can also be maintained at each PC.
• All transfers can be secured on the host using signon authorization. An extensive set of security options are available to limit access to host datasets, reports, and members to appropriate PC users. A user exit can also be written to perform security checks not normally supported by PC/Transfer.
• Transfers can be performed by request or can be automated.
• Data can be transferred in either EBCDIC or ASCII, with or without CRLF separation.
• A script language is provided for both the PC and the Host for use during all downloads. Scripts can be used for record selection and data format conversions. The PC script can also be used for other file conversions.
• A PC upload script can be used to concatenate PC files, and/or wrap host JCL around files during uploads.
The PC user will be required to enter a user ID and password each time the PC program is started.
The main program window, shown above, is divided into two list boxes. Initially, both lists are empty. As you select items for upload and/or download, the upper list will fill in with the pending transfers. The lower list is filled in response to a download query request.
Access to host files is based on what PC/Transfer refers to as “Transfer Categories”. Categories define the type of information that can be transferred, and which PC users can have access to the information. A dialog similar to the one shown below is displayed when PC/Transfer needs to known what category is desired for a specific transfer. The dialog will only contain the categories that the specific PC user is authorized for.
A download (from mainframe to PC) request is a multi-step process. First, you need to select the mainframe category that you wish to download from, and then you will need to supply some selection criteria for that category. Once the selection criteria is set, this program will enter into a conversation with the mainframe to obtain a list of available files for download purposes. The list of available files is put into the lower list box in the main window. You can then select one or more files for download by clicking with the PC mouse on the relevant entry in the list.
An upload (from PC to mainframe) request is also a multi-step process. Here, you will first select the PC file that is to be uploaded to the mainframe. Then you will determine the category to upload the file into and fill out necessary identifying information specific to that category.
In neither case will the actual file transfer occur at this time. Instead, your selection will be placed in the upper list box in the main window. You can review and/or change your selections prior to transfer by clicking with the PC mouse on the appropriate selection entry. When you are ready to transfer data to or from the mainframe, select the transfer option from the File Menu. Both uploads and downloads may be mixed within a transfer operation.
