Re: Where is the data compression manual SA22-7208
John, I tried sending you the PDF version of the manual via offline message, but looks like your email address is not accepting them. If you want a copy of the pdf then email me directly. Thanks.

Re: Where is the data compression manual SA22-7208
Mike, Alan, and Ed, Thanks for your suggestions. I'm retired, so really have no need for compression. What I am doing is trying to help Don Higgins with enhancements to z390. He suggested that I start with the compression/decompression instruction. When I looked up the instruction in PofOp (SA22-7832-12), I found the reference to SA22-7208 on page xxx, where it states "The z/Architecture form of the COMPRESSION CALL" instruction is described in this publication". Wanting to be complete, I assumed that I also needed that manual. Maybe I don't. PofOp "Appendix D. Compression Call Facility" may be enough. Ed: Is PofOp the doc you mean? I may have bitten off more than I can chew. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
Re: Where is the data compression manual SA22-7208
Hi John, Not sure what your situation is, but Ed Jaffe is quite right, the compression described in that manual is pretty awful from compaction and efficiency standpoints, and maybe the API as well, I don't recall. If you need a good x-platform data compression library that runs on z/OS, Linux, Unix, Windows, and others, you can't go wrong with zlib. It is what IBM uses for their zEDC compression adapters, and is the software behind the curtain for the z15 'Integrated Accelerators'. In addition it is extremely well supported by the authors, Mark Adler and Jean-Loup Gailly.

Alas, my PC runs Linux. Softcopy librarian appears to be Windows-only Its been a while since I ran it in linux. IIRC, its java with some extra stuff. Try 7z or another archive extractors to get it unpacked. Take a look at the .bat files. They run java with a jar file... just translate the commands. My notes indicate I had better luck with 3.8 than 4.0. Although there appears to be 5.x versions now. The FTP directory linked ftp://public.dhe.ibm.com/ps/products/bookmanager/tools/ is open and you may find other useful bits there.

Re: Where is the data compression manual SA22-7208
Thanks. Alas, my PC runs Linux. Softcopy librarian appears to be Windows-only even though the link you provided to get it indicates that it runs on Linux and Windows. Looks like Linux support has been removed. The following link https://www.ibm.com/support/pages/node/724765 claims to have softcopy reader for Linux (version 3.7), but clicking the link yields a "we're sorry; link may have been moved or deleted". The link where SA22-7208 was found has an option to read it online as well as download it via HTTP. Hovering your mouse over the button for "Read" shows publibfp.dhe.ibm.com/cgi-bin/bookmgr/books/dz9ar602 but clicking it takes you to https://www-01.ibm.com/servers/resourcelink/svc00100.nsf/pages/zos-library-archives?OpenDocument which is PDF books only. (I did search through the various links there for SA22-7802 but did not find it.) I was able to download dz9ar602.boo via the "Download HTTP" button, but I can't read it without a reader! Summary: found the book but cannot read it online; can download the .boo version, but cannot read it since there does not appear to be a Linux version of softcopy reader. A web search for "linux version of ibm softcopy reader" yielded a promising link https://www.ibm.com/support/knowledgecenter/SSLTBW_2.1.0/com.ibm.zos.v2r1.ab0in02/ab0in02298.htm but the instructions there led me down the same path as above. Ditto for the instructions found in GC31-8311-47 "Installing, Managing, and Using the Online Library". Anyone have any other suggestions? -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

Where is the data compression manual SA22-7208
The latest Principles of Operation (SA22-7832-12), item 8 on page xxx, indicates that the compression facility is described in SA22-7208. However, I am unable to find anything but references to "SA22-7208". There is a post from 12MAY2011 asking the same question. Following the links provided there took me to an IBM site where manuals for z/OS 1.13, etc. Looking through these was a dead end. Anyone know where I might find the manual? -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
