New Enhancements
The Unicenter® TCPaccess™ FTP Server affords high throughput and low resource utilization. It provides detailed management information on its health and status of FTP file transfers, enabling Unicenter® NetMaster™ File Transfer Management to provide heightened awareness of your transfers. The Unicenter TCPaccess FTP Server can run on Unicenter® TCPaccess™ Communication Services or IBM’s Communications Server for z/OS and OS/390.
Unicenter TCPaccess FTP Server extends your investment in Unicenter TCPaccess TCP/IP Server, Unicenter® NetMaster™ IP and Unicenter®
NetMaster™ Operations for File Transfer Management Enterprise companies as well as remote users are becoming increasingly aware of FTP and its importance to E-Business. Knowledge of FTP capabilities, ease of use, and availability on commonly used operating systems such as Windows, UNIX, Linux, and z/OS and OS/390, have resulted in FTP usage increasing at a fantastic rate. Due to the availability of FTP, the cost of additional client software is eliminated, therefore providing immediate and convenient access to Enterprise data. FTP is the world standard for Enterprise data transfer. As a result, systems administrators require visibility of file transfers to effectively monitor and control z/OS and OS/390 FTP usage.
This document describes the Unicenter TCPaccess FTP Server's new features:

FTP Data Compression Implemented
1–2 Release Summary
FTP Data Compression Implemented
Data compression typically improves network link performance with very little cost in CPU overhead—now implemented in the Unicenter TCPaccess FTP Server.
This feature is most beneficial across networks where link bandwidth may be constrained. Data compression is designed to minimize the amount of data sent across networks by reducing occurrences of repetitive data down to one- or two-byte representations. Printer files, which tend to contain many repeated blank characters, are good candidates for data compression.
Users can choose one of several compression techniques described in the
Administrator Guide. If configured at Unicenter TCPaccess FTP Server startup, data compression is active for a given FTP session only if requested by the FTP client.
ISPF Statistics Handling
Unicenter TCPaccess FTP Server now provides control over how ISPF statistics are included in the directory entries of target PDS members. ISPF statistics for the target PDS member can either be exported from the source PDS member, or created or updated by the Unicenter TCPaccess FTP Server.
These statistics include:
n Create or change dates n Modification level or version n Module sizes
n User ID
See the User and Administrator Guides for details.
Machine Carriage Control Support
Support for the transfer of files containing machine carriage control characters is included in Unicenter TCPaccess FTP Server. The FTP user must select
transmission type of E ("TYPE E") before issuing a FTP data transfer command for sending/receiving machine carriage control (that is, RECFM=FM) data sets.
Migration Aid for Users of IBM TCP/IP for MVS FTP Server
New Enhancements 1–3
Migration Aid for Users of IBM TCP/IP for MVS FTP Server
A migration aid is provided that will create or update a set of Unicenter TCPaccess FTP Server configuration parameters that are comparable to an existing set of IBM TCP/IP for MVS FTP Server configuration statements is now available.
Load Module Transfer
Load module transfer allows MVS load modules to be transferred between load libraries on different hosts or the same host. The FTP clients and servers
participating in the load module transfer can be either Unicenter TCPaccess FTP Server components or IBM Communications Server for OS/390 FTP Server components. For load module transfer to be successful, all Unicenter TCPaccess FTP Server components must be at a minimum release 6.0 SP1. All IBM
Communications Server for OS/390 FTP Server components must be at a minimum release of V2R10.
See the User Guide for details.
Common INET (CINET) Stack Recovery
The Unicenter TCPaccess FTP Server may be notified by CINET when a new transport provider is started. The notification is not received immediately after the new transport provider becomes active, but rather when the FTP Server next accepts a connection. This connection must necessarily come through a transport provider other than the transport provider just started. When the notification is received, the FTP Server enables itself to accept connections from all active CINET transport providers, including the transport provider just started. See the Administrator Guide for details
User Control of Creation of Raveled Files
1–4 Release Summary
User Control of Creation of Raveled Files
Using the RAVEL parameter of the SITE command you can specify whether or not a file should be raveled.
When the FTP server stores or retrieves a file, the following criteria determine whether the file will be raveled:
n If the record structure was specified (usingthe STRU R command), the file
will not be raveled
n If SITE RAVEL is specified, the file will be raveled
n If SITE NORAVEL is specified, the file will not be raveled.
n If it is a RETR operation and the input file is a JES spool data set, the file will
not be raveled.
n If the records are blocked (RECFM includes B), the file will not be raveled.
Otherwise, the file will be raveled. See the User Guide for details.
