PKZIP for z/OS
Products PKZIP Mainframe
Feature Function Benefit Standard Enterprise
ZIP archives Reduces file size by as much as 95% Reduce costs through the conservation of network bandwidth, storage space, and backup tapes check check
Hardware- accelerated compression Compresses files using System z hardware Improve workload throughput by using less CPU overhead to perform file compression check check
Customize static dictionaries Enables better compression ratios by tailoring static dictionaries to your business data Experience greater storage savings and smaller files spanning your network no check
UNIX File System Support Provides direct access to read or write files on Windows® or UNIX® servers by the z/OS operating environment Reduce total elapsed processing time by decreasing the number of steps needed to create and extract archives check check
International code table support Supports standard IBM® code page translations and comes complete with recommended code pages for many popular languages including Danish, English (U.S. & U.K.), Finnish, French, German, Italian, Norwegian, Portuguese, Spanish, and Swedish; other code pages may be applied as well Empower cross-platform communications by translating characters & symbols into readable information when converting between EBCDIC and ASCII check check
Mainframe-centric file handlers Uses file handlers native to z/OS, including SEQ, PDS, PDS/E, VSAM, and magnetic tape data; allows ZIP archives to be stored as SEQ, VSAM, and magnetic tape datasets, as well as PDS or PDS/E members Reduce the complexity and cost of managing and storing data maintained in necessary mainframe formats

Improve productivity by reducing the steps required to manage files in their native formats 		check check
Simulation mode Performs test scenarios to predict compression outcomes without using the CPU cycles required to perform the entire operation Simplify file selection by identifying the files most efficiently reduced in size check check
SafetyX control Protects critical files from being overwritten Preserves system integrity and prevents the inadvertent destruction of data check check
Multiple integration interfaces Includes batch processing through JCL and Command Line Interface (CLI) through the command processor

Supports calling from a REXX EXEC, a COBOL routine, or ASSEMBLER 		Reduce the complexity and cost of natively adding ZIP compression processing in-line to existing or new applications

Issue commands and exploit product capabilities using an interface of choice 		check check
ISPF panel integration Allows operators and systems programmers to initiate actions ad hoc, using 3270 screen menus and displays, through integration with IBM’s Interactive System Productivity Facility (ISPF) Simplify product configuration updates through an interface most commonly used by systems programmers and operators check check
Data integrity checking Ensures 100 percent data integrity for data compressed and sent from one system to another using 32-bit Cyclic Redundancy Check (32-bit CRC) Preserve data integrity and prevent the inadvertent destruction of data check check
Self-extracting files for other operating systems Formats ZIP archives as self-extracting files for Windows end-users or for UNIX/Linux and Linux on System z operating systems so compressed data can be easily unzipped in one easy step Improve user productivity by eliminating manual steps required to access files check check
Very large archive support Over 2 billion files can be included in a ZIP archive Enables customers to simplify the management of file archives; meet IT business requirements check check
Decrypt SecureZIP passphrase-encrypted archives Decrypts and extracts files that are passphrase-encrypted by SecureZIP products Maintain control of data by decrypting files using an organization-elected methods of encryption (including files protected with public and private keys) check check
Enhanced tape processing Reduces the time needed to write files to, and extract files from, tape media; files are written directly to tape media, bypassing the need to stage them to disk first

Finds files quickly in larger ZIP archives held on tape 		Improve user and staff productivity by reducing the number of steps and amount of time required to access data check check
zIIP Support Offload processing to IBM z Integrated Information Processors (zIIP). Free up general computing capacity and lower overall total cost of computing for select workloads. check check
