JES2 check point in CF and DR
Anyone out there mirroring their DASD either SRDF or XRC, i'd like to know how you handle the JES2 check point. We currently have our primary check point in the CF and second one on DASD. We know they aren't in SYNC maybe a few writes behind on DASD. We mirror using IBM XRC to another site for DR purposes. We are thinking of taking both check pints and moving it to DASD so both check points are mirrored. I guess the basic question we are asking ourselves is it worth putting the check point back on DASD and loose the benefit of the CF or keep it where it is an the heck with a few pieces of output that might be lost at the time of a disaster. If your mirroring and have gone down this road what have you done and why?

SHOWzOS and z/OS R9
Hi, I will release SHOWzOS 7.16 for z/OS R9 after APAR OA22594 will be closed. Hopefully I'll fix the problems I have with my own CEEOCB because z/OS R9 deliver a CEEOCB in the SCEEMAC.

Re: Open 3270 connection on the net??
Jim, Do you happen to remember whether there was a locked padlock symbol at the lower right of the Host On-Demand window? If so, that would indicate that the connection is encrypted. A few years ago I did an awful lot of work with a particular state government to help them get Host On-Demand installed and properly secured for their needs. In their case the accessible mainframe applications and data were (are) very valuable and very private, including such things as the state prison system records. So we had a lot of reviews, discussion, design consultations, etc. to configure Host On-Demand appropriately. What you observed would not be possible, for example. But other state systems vary. There are even a few totally open and public 3270 access points, such as university library book catalog systems. One thing that's usually a requirement for any system that demands a logon is to encrypt the connection. Otherwise it's much easier for someone to intercept the logon information (user ID, password). So if indeed there is a hole here -- and I agree about reporting it -- then probably the very first remediation I would take is to get that HOD session encrypted. (That's assuming the Internet access is needed; often it is.) I'm not talking about "https" in the Web address -- that's irrelevant and unnecessary, actually. HOD isn't the part that needs protection. It's the 3270 connection itself, indicated by the padlock at the lower right. Now, that may not be sufficient -- it wasn't for my particular state government customer -- and additional design steps may be warranted. But it's a basic configuration setting which is quite important for most. Ever since at least OS/390 V2R6 (I think) it has been quite easy to enable SSL for TN3270E on the host side. - - - - - Timothy Sipples IBM Consulting Enterprise Software Architect Specializing in Software Architectures Related to System z Based in Tokyo, Serving IBM Japan and IBM Asia-Pacific E-Mail: [EMAIL PROTECTED] -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

As a University the campus still on the mainframe (all all in the past) used HOD for student registration. Since students could be anywhere, it was open to the world. It's not a VTAM login, it's SuperSession, so you can only get to certain things. We have had a few DOS attacks at certain userid's but they are either non existant or protected.

Backing out of COMPRESS(TAILORED)?
I just learned about, and turned on, COMPRESS(TAILORED) in SMS. Things were working OK, then we had a user job abend because the region size was too small (213-ED abend, with 378 abend also showing); trying to browse the dataset after that got 213-E0. We were able to recover this job and change the region size, but it did raise a question: Once I have turned on tailored compression, if I wanted to switch back to the generic version, what would happen to any datasets that were compressed with tailored compression? Would I have to identify them somehow and uncompress them before turning the option off?

Re: zH/OS (z/OS on Hercules for personal use only)
PWD members still can download tons of IBM software. I'm not claiming to have been misquoted, but my comment about Hercules or "whatever" was meant for PWD members (or anyone deemed by IBM to be worthy in some way to get the ADCD for z/OS or z/VM), and not meant to say that z/OS/z/VM should be released to the wild. Though I would like that, too, I don't see it as realistic. IBM still lets PWD members license ADCD's so the only thing stopping that is that (IMHO iPhone/AT&T style) relationship between them and FSI. People in this software game have influence on what other people buy and use. Hypothetically speaking, of course, I could say HP or AIX, and I could say I recommend WebLogic or WebSphere. Now, hypothetically speaking, if as a PWD member I can download WebSphere and learn it, then hypothetically if someone asked me I could say that WebSphere is a good choice. (WebLogic is good, too.) People can think otherwise, but in my humble opinion, unless it is running on mainframe hardware it isn't a mainframe in any sense of the word. It could be emulating one for development or training or other purposes, though. In my opinion this very clear line has been blurred a bit (by PSI et al). Let me put it another way (my opinion of course): What sorts of things might people come up with if they had a $1000 PC running z/OS to develop on in their spare time? And I mean things that they could never do on a real mainframe at their work. There're a million things I'd love to try and learn about when I can't sleep. I've been a fan of IBM mainframes since 1983 and I've never, ever, in my life ever written to an APF controlled library. Some of us just aren't so lucky. )-: Or put another way.

Besides, for STRICTLY PERSONAL USE, there is ZERO justification (my MVS 3.8j runs at about 3 MIPS on a dated 800 MHz Pentium). Indeed, IBM is first and foremost a marketing company. We must explain our hype and the commercial value stemming from it to MBA's, IBMers who know Microsoft's at least 1'000 times better than IBM's own software: 1) as a kid you learn Microsoft's products, IBM's come after college ! 2) more and better trained z/OS specialists eases the pressure on CIO's to migrate to "much better" non-IBM platforms. Why "much better"? Often for no other reasons than lack of IBM expertise in the ranks and, according to your collegues, "the fact" that the "best" IBM has to offer wasn't even built by IBM (z/Linux). 3) Operating and maintaing zH/OS requires pre-requisite knowledge while at the same time it is a tremendous motivator to learn and practise (and it doesn't replace IBM Education either. It creates a craving for more!). 4) a zH/OS lets one validate concepts, ideas, test "exits" (things IBM provides) and much more, things you can't do at work in a spare LPAR (because there never is a 100% guarantee it won't crash the system or some parts thereof). 5) About 3 years ago I downloaded a Linux distro, installed Apache, MySQL, Perl packages.

When MGCRE was introduced, there were minimal structural changes made to the rest of SVC34 proper. The front end module (IEE0003D) was updated to accept a new kind of parameter list and munge that data to look like a command was issued. Notable changes were the 4-byte console id, console name and CART. It wasn't until the console restructure that MCS support was actually changed to issue MGCRE, about 15 years after it was introduced. The control blocks that transport the command to the various exit points, routers and command processors were really only tweaked to use the new source/target console information, so the 126-byte limit was never relieved.

Precisely. The stingy use of memory dates from a time that the CSCBs and CIBs were in 24-bit common.
