PKZIP for z/OS

Get bottom line cost reductions from conservation of bandwidth, storage space, and backup tape. PKWARE uses industry-leading algorithms that compress files more efficiently than free compression libraries such as ZLIB.

ZIP archives are portable data containers that can be read and decompressed on many operating systems. PKWARE is the only single-source vendor of ZIP compression products across the major enterprise operating systems - interoperability is guaranteed.

PKWARE is the original developer of the ZIP compression format. Since its inception, PKWARE has made ZIP specifications freely available to the public as a standard for compressed data storage. Consequently, ZIP is one of the most widely used file formats in the world. PKWARE is continually reinvesting in added functionality for PKZIP brand products, making it the unquestioned leader in the industry.

Unlike other vendors who offer support only through email or online forums, PKWARE's experienced technical support staff offers live telephone support in addition to web and email support should any issues ever arise.

Data files intended for other operating systems can be automatically translated from EBCDIC to ASCII language sets, making data transfer much faster and easier. Equally, ZIP files created on ASCII platforms can be easily read on zSeries.

PKZIP supports standard IBM code page translations, and comes complete with recommended code pages for many popular languages, including Danish, English (US & UK), Finnish, French, German, Italian, Norwegian, Portuguese, Spanish, & Swedish. Other code pages may be applied as well.

PKZIP for zSeries 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 data sets, as well as PDS or PDS/E members.

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

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.

Critical system files cannot be accidentally overwritten.

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.

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

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.

PKZIP can compress files over 9 exabytes in size.

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

PKZIP Enterprise Edition can decrypt and Extract files from SecureZIP Archives

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

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.
