PKZIP® for z/OS® - Feature Benefits
ZIP archives reduce file size by as much as 95%
Get bottom-line cost reductions through conservation of bandwidth, storage space, and backup tapes. PKWARE® uses industry-leading algorithms that compress files more efficiently than free compression libraries such as ZLIB.

International code table support
PKZIP 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.

Mainframe-centric file handlers
PKZIP for z/OS was designed specifically for IBM mainframe operating systems. File handlers include SEQ, PDS, PDS/E, VSAM, and magnetic tape data. PKZIP also allows ZIP archives to be stored as SEQ, VSAM, and magnetic tape datasets, as well as PDS or PDS/E members.

Cataloged tape dataset processing
Administrators can request a tape dataset to be compressed without providing all the DCB attributes — making archive or backup compression quicker and easier.

Simulation mode
Administrators can test scenarios to predict compression outcomes, without using the CPU cycles required to perform the entire operation, so they can make informed decisions on processes before committing precious resources.

SafetyX Control
Critical system files cannot be accidentally overwritten.

Multiple integration interfaces
PKZIP includes batch processing through JCL, an intuitive ISPF interface, and CLI (Command Line Interface) through the command processor, all of which are also ways to invoke PKZIP. Calling PKZIP from a REXX EXEC, a COBOL routine, or ASSEMBLER is also supported, so administrators are free to select the type of integration that is most appropriate.

Data integrity checking
32-bit Cyclic Redundancy Check (32-bit CRC) guarantees 100 percent data integrity for data compressed and sent from one system to another.

Self-extracting files for other operating systems
ZIP archives can be formatted as self-extracting files for Windows end users or for UNIX®/Linux® operating systems, so that compressed data can be easily unzipped in one easy step.

Large file size support
PKZIP can compress files of over 9 exabytes in size.

Very large archive support
Over 2 billion files can be included in a ZIP archive.

Decrypt SecureZIP passphrase-encrypted archives
PKZIP Enterprise Edition can decrypt and extract files from SecureZIP® archives.

ISPF panel integration
Integration with IBM’s Interactive System Productivity Facility (ISPF) allows system operators to initiate PKZIP actions ad hoc, using 3270 screen menus and displays.

Enhanced tape processing
Significantly reduce 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.
