MAXSOCKETS and INADDRANYPORT are not related to each other
Cross-Post to MVS-OE and IBM-Main Quite a while ago, there was a question (I don't remember on which list) regarding the relation between MAXSOCKETS and INADDRANYPORT, since the IP Comfiguration Guide seems to imply there is one. I had sent an RCF back then and have gotten an answer today. Both my RCF and the answer are attached below. It may be the question originated from the TCPIP list, which Im not subscribed to. If someone wants to forward the post to that list, feel free to do so. Peter Hunkeler CREDIT SUISSE From: Michele Carlo [mailto:[EMAIL PROTECTED] On Behalf Of COMSVRCF EMAIL Sent: Monday, January 22, 2007 5:27 PM To: Hunkeler Peter (KIUK 3) Subject: Re: RCF for z/OS IP Configuration Guide Peter, I regret it has taken us so long to get back to you with an answer. The UNIX System Services developer agrees that there is no relationship between the MAXSOCKETS and the INADDRANYPORT values. We plan to clear up any implications in our documentation. Thanks for alerting us to this situation. Michele Carlo for z/OS Communications Server Customer Information IBM Research Triangle Park, NC The RCF I had sent: Hello, There was a discussion about the relation, if any, between MAXSOCKETS and INADDRANYPORT, as impled by the following paragraph: Book: z/OS Communications Server IP Configuration Guide Version 1 Release 7 (SC31-8775-07) Topic: 1.2.14.4 Specifying BPXPRMxx values for a CINET configuration Paragraph: 3 INADDRANYPORT and INADDRANYCOUNT specify the first ephemeral port number and the range of ports for z/OS UNIX CINET usage. *** The starting port number should be set at least as high as the value for MAXSOCKETS. *** . The last sentence, marked with *** seems to say there is a relation. I'm not the IP expert but this doesn't sound reasonable to me given the fact that MAXSOCKETS has a valid range from 0 to 16777215 and INADDRANYPORT must be in the range from 1024 to 65534. Also, I understand MAXSOCKETS to define the size of socket table for a given address family. INADDRANYPORT/COUNT tell the CINET layer what range of ports has been defined to be the ephemeral port space. This must match the PORTRANGE in the TCP/IP profile(s). I don't see how MAXSOCKETS and INADDRANYPORT are related. May I kindly ask you to verify the paragraph in question?

Re: COBOL and Java interoperabitiliy
RedHat Linux. I think it would be interesting to see if we could create some glue on z/OS so that Java on Linux could use JMS to talk to Java on z/OS, which would then use some legacy COBOL I/O routines or business logic. Why not do the glue in COBOL, after all, it is just MQ-Series at that end. You should be able to get to the messages through JMS at the other side without having JMS at the COBOL side, no? Myself, I have written some JNI glue that enables one to invoke a Java method from a COBOL program and to invoke a COBOL sub-routine as a native method. But that is all running happily on zOS.

Central Standard Time, [EMAIL PROTECTED] writes: Prohibit reading beyond DS1LSTAR, and enforce management of DS1LSTAR so it is never allowed to point past uninitialized space. An unauthorized program can read beyond DS1LSTAR quite easily as long as allocation builds control blocks describing all allocated tracks rather than just those from the beginning of the data set to the track pointed to by DS1LSTAR. An unauthorized program can also read residual data beginning at the next track after any EOF record written to try to prevent this. All it takes is EXCP. IBM would have to add more validity checking into EXCP in order to prevent accesses beyond DS1LSTAR, which would cause big problems for some sophisticated applications, I'm sure. Higher level access methods, such as BSAM, QSAM, BPAM, BDAM, and VSAM all suffer from the same exposure. In fact, the exposure exists for all access methods, since an unauthorized program can do an EXCP to any allocated track mapped in the TIOT. Just because you use QSAM for most of the application's work does not mean you cannot have an EXCP in there somewhere that uses the same or a different DCB than that which QSAM is using.

IIRC this refers to any dataset that has not been openned that is SMS managed. What I see is: #3.2.6.3 z/OS V1R7.0 DFSMS Using Data Sets __ 3.2.6.3 Factors to Consider When Allocating Direct Access Data Sets When the system allocates a new SMS data set with DSORG=PS or no DSORG, the access methods treat the data set as being null, that is, having no data. A program can safely read the data set before data has been written in it. This means the first GET or first CHECK for a READ causes the EODAD routine to be called. Hmmm. I had understood that this works only if DSORG is known. But the wording appears back to the oldest OS/390 doc I find on publibz. And note that the mechanism is not described. It could be by writing an EOF at the beginning; it could be that a flag is set (in the DSCB?) to indicate that the data set is uninitialized. Note that it mentions GET and READ, but not EXCP. And it does not mention any PARMLIB option. For data sets other than system managed with DSORG=PS or null, the program will receive unpredictable results such as reading residual data from a prior user, getting an I/O error, or getting an ABEND. Reading residual data can cause your program to appear to run correctly, but you can get unexpected output from the residual data. You can use one of the following methods to make the data set appear null: 1. At allocation time, specify a primary allocation value of zero; such as SPACE=(TRK,(0,10)) or SPACE=(CYL,(0,50)). This I've done this; it works. technique does not work with a VIO data set because creation includes the secondary space amount. Alas. It mostly works, but there's likely a performance impact.

Re: user friendliness
User friendliness (UF) is an inchoate notion. Applications need to be UF. Not all systems interfaces need be or even should be UF. Circa 1910 anyone who undertook an automobile trip from Paris to Lyon or New York to Philadelphia needed to be qualified for membership in the [not yet founded] Society of Automotive Engineering in order to have any prospect of completing his trip. This is no longer the case. Such trips are now unremarkable because the infrastructure required for them is in place. Interestingly, however, the SAE has not been abolished. The needs and preoccupations of automotive engineers are very different from those of car drivers; but they are complementary in the sense that car drivers must look implicitly to automotive engineers for progress in car design and performance. Individual error messages may be clear or muddled, require revision or not; but reifying the content of a message into a generic complaint about a z/OS UF deficiency is not helpful. Many of the messages produced by z/OS are already too user friendly, in the special sense that when parsed they turn out to be saying: It's too complicated, and you wouldn't understand anyway. UF is inseparable from dumbed down content. This is perhaps---I'm not sure---regrettable. It certainly means that different kinds of manuals are needed for different kinds of people.

Saving your old tapes
Hi Folks, It just occurred to me after having a discussion with a fellow sysprog that most of us have old tapes and cartridges lying around (collecting dust) which have potential usefulness if they'd be converted to DVDs or CD roms and put into AWS format. The technology is certainly available for that, and it's a lot easier to store (say) 2 DVDs than 20 or 25 carts (or 2400 foot reels). Many of us, who were hoarding old tapes, not knowing what would be done with them, of course never anticipated that you can run MVS on a PC. (And you LEGALLY can run 1975-vintage MVS 3.8 at home.) So even if you think your old tapes aren't useful, you can make them useful to SOMEBODY, and the other side is, that CDs and DVDs take up a whole lot less space than tapes do. And also, you can make duplicates of CDs and DVDs much more easily, so they can be saved for longer. I wanted to put this idea out to the public, because people often don't think of that. Since I do a lot of software archiving (being the co-proprietor of the CBT Tape collection), I have a tendency to think along those lines. Anyway, if anybody is interested, please say something.

So even if you think your old tapes aren't useful, you can make them useful to SOMEBODY, and the other side is, that CDs and DVDs take up a whole lot less space than tapes do. And also, you can make duplicates of CDs and DVDs much more easily, so they can be saved for longer. By all means, ancient software from the mainframe world should be saved. Relatively little from before 1980 still exists from IBM, and extremely little from most other mainframe companies. If you find an old tape disk, or even stack of cards, please look into giving or lending them to an archivist to save the bits, such as the CBT folks or CHM. I suppose I will toot Computer History Museum's horn again - sorry about that, I am trying not to steal CBT's thunder - but they are doing a great job of saving what is out there from IBM and the BUNCH. The museum is not just hardware and manuals - there is a full time software curator on staff, and he can handle many interesting problems with old, and often failing, media. Yes, there are probably some legality issues for some of it, but as far as I know IBM has never bothered CHM about it. This is probably a question best answered by the CHM staff. And as the software gets older, the problem tends to go away.The important thing is that the bits are saved. -- Will -- 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

Re: What is command reject trying to tell me?
Alan, let me give you a less crabby response. I admire IBM and its products, and the mainframe has provided a good living for me. The support center would be an inappropriate resource, based on my experience. I believe they do not help with problems -- they resolve defects. Had I called them up and said what the heck does this message mean? they would have (politely) told me to go away. OTOH, this listserve was great! The people here told me, in several fits and starts, what the message indicated. Was it authoritative? No, by the listserve's nature, it was not. However, I was able to take the advice given here and correct the error, which is for me the ultimate authority. Could I have tricked the Support Center into solving the problem? Probably -- called them up and fibbed I have a DFSMS defect -- this perfectly good dataset and my perfectly good QSAM program won't read it. With any luck, they would eventually have come around to telling me that DFSMS was either WAD, or almost WAD, and my dataset was missing a BLKSIZE. They might have issued a PTF, which would not solve my problem -- my program would just fail with an S013 rather than a Command Reject. I would still have had to change my code to solve the problem (and I'm not for a second objecting to that). This listserve required a note from me that took 5 or 10 minutes to compose, and 53 minutes later I had the essential clues from Bill Fairchild (thank you, Bill!). I doubt that the Support Center would have done as well. It is, after all, set up to serve a different need. Can you criticize me, OTOH, on the basis that things will never get better if people don't report problems? Guilty as charged. Frankly, the hours in my day are limited, and the time I have available for good deeds I allocate to causes that are more worthy of charity (IMHO) than IBM. IBM has dozens of employees who read this listserve. If it is not worth it in IBM's management's view to seek out problems here and put in the effort necessary to solve them correctly, then why should it be worth it to me?

z/OS 1.7 SYNCHRES=YES z/OS 14 SYNCHRES=NO
I have checked the manuals and the archives on this and I am still unsure about mixing the yes and no values for SYNCHRES in a GRSPlex (Basic sysplex if that matters any). I need to bring my TEST LPAR into our plex for testing. I would rather wait until either our outage weekend next month to change the value of this on the systems that are already in the sysplex or until each cuts over to 1.7 but I need to bring the TEST system up in the plex and test before I can migrate 1.7 to the next system. I see that I can change the value via the SETGRS command and I guess I could always code the 1.7 system as SYNCRES=NO for this phase but from the way I interpret the FM it doesn't seem like it should be a concern. However, nothing I found gave a definitive answer. Does anyone know of any problems with having two z/OS 1.4 systems with SYNCHRES=NO and a z/OS 1.7 systems with SYNCHRES=YES active in a basic sysplex?

Just tell them this is a requirement.How many such rules do we live under that we don't understand. The bad part about such rules isn't how hard it is to get them, but how hard it is to get rid of them. (There usually isn't any review to find out whether the rules still make sense). It's interesting that testing standards I've seen for OO systems are nowhere near as rigorous as testing standards I've seen for traditional systems. The reason is that there never is total ownership of whatever you use in OO, so the testing standards can't be as rigorous. So people compare time of development and see that the old systems take longer to program. It's really the testing that takes longer.Maybe the standards should match. I worked at a shop which had both PL/I and CoBOL programs.One reason that people chose PL/I for some programs was because it included bounds checking.Actually, what it included was no option to turn off bounds checking. And the standard for the CoBOL programs (established by a long gone systems person), was to set the compile switch to not do bounds checking.That standard didn't make sense with the more powerful machines, when the big cost was in maintenance instead of CPU time - and it especially didn't make sense if people chose their computer language to get around this standard. Well, some people choose Java to get around old standards instead of choosing it for its strengths. -- 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

I went through a z800 to Z9BC upgrade a few months ago and encountered problems with the 2096DEVICE PSP bucket. It could be that we were one of the first to get a Z9BC, but I was missing maintenance. The maintenance I missed was added the week before we upgraded. I learned to keep watching PSP. We IPL'd fine and got everything up and running, but when I tried to add new DASD through HCD, I got mis-matches all over the place. We had some issues with our vendor with conversion too, but missing the maintenance was the worst part. I don't know if the MP3000 uses PCHIDs, so you might be able to ignore this. If you can see PCHIDs via HCD in your converted IODF on your MP3000, then you have the maintenance I missed. Also be very careful with your conversion process for the IODF. I kind of counted on guidance from our vendor and I got it all messed up. The doc I found to be most complete for this was actually conversion from 9672 to z890. I can't find it right now, but ask your vendor about the IODF conversion process. If they get a glazed look, then say something and I'll find the doc I used. It's not that hard, but it's kind of convoluted in that you have to export the IODF, run it through a PCHID mapping tool, and then import it back. -- 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

ASCII and NON-XPLINK
Hi,
I was trying to compile the Openldap package on z/OS 1.7 using XPLINK and
ASCII, unfortunately I ran into lots of linker problems, the same as
encountered by Howard Chu in Apr 2003
(http://bama.ua.edu/cgi-bin/wa?A2=ind0304L=ibm-mainP=R65156I=1X=0610C276E0EE724152Y=weberjn%40gmail.com)
I only got the ASCII option to work with XPLINK using c89, there seem to be
no NON-XPLINK Ascii libraries, at least the linker does not find them.
If I compile the code below using
I tried c89 -Wc,ASCII -Wl,ASCII hello.c
I get errors.
So, did I use wrong options or can't ASCII programs be compiled with NON-XPLINK?
Thanks,

There is no option to control this.

I thought someone once informed me that the reason I didn't get an EOF in a particular instance was that SMS couldn't determine the DSORG. I'm tempted to try again. They could have easily done this for non-SMS as well, but I guess they opted for compatibility. Compatibility with what? Is there some application that depends on uninitialized space not starting with an EOF? That can't generally be guaranteed. But I'd suggest the EOF not be written when ABSTRK is specified -- someone might be trying to recover deleted data. That said, I try not to urge that such solutions be retrofitted to obsolescent environments such as non-SMS.
