Re: a C language question....
Well, this code compiles perfectly under SuSE Linux 9, so I think that the
compiler is telling you it cannot find any function named getaddrinfo().
Make sure you have the correct MACLIBS or whatever the C compiler uses
set up.
Come to think of it, what C compiler are you using under VM? Is it a
freebie? :)

Subject: a C language question
I know that this is the z/VM forum, but I have a question about
compiling a C program on CMS, so I'm hoping someone here might know the
answer.
I've written a short C test program that invokes the new getaddrinfo C
library function. However, the z/VM C/C++ compiler complains with the
following error message when I attempt to compile my test program:
#define _OPEN_SYS_SOCK_IPV6
#include netdb.h
#include sys/socket.h
#include stdio.h
#include errno.h
#include stdlib.h
#include string.h
struct addrinfo hints, *res, *res0;
int main(int argc, char *argv ) {
int error;
int s;
char *name = www.cacert.org;
char *port = 80;
const char *cause = NULL;
memset(hints, 0, sizeof(hints));
hints.ai_family = PF_UNSPEC;
hints.ai_socktype = SOCK_STREAM;
error = getaddrinfo(name, port, hints, res0);
...a..
= a - CCN3023 Expecting function or pointer to function.
Can anyone tell me what I'm doing wrong (besides the obvious fact that I
am reduced to using C as a programming language, which has to be one of
the worst tools ever devised..the use of C has set back good software
development by 20 years, imho.)
Thanks for any help and have a good one.

Re: Another long slow decline.
Laugh back at them - how much do you pay per month in z/OS licensing? :) z/VM is a OTC (One Time Charge in this case) product, listing at something like $40K per IFL. Linux from SuSE has a $5K per year support/subscription cost, and if you don't pay the sub,you can still use the product. HLASM from Dave Rivers is *amazingly* affordable. We could probably be coerced into licensing some software. :) All in all, the reason we went this route in the first place was simply the licensing costs for z/OS and CICS. The only significant costs we have are hardware maintenance, and those are roughly equivalent to the same costs on PCs or RS6000, or even iSeries machines. On the other hand, we have had exactly 20 minutes of downtime in over three years, and that was caused by a service element. Go figure... We needed an interactive environment that would allow us to port green screen apps, do web apps, client server, and so on. The development environment we use is incredibly productive for Assembler too - easily comparable with a COBOL or Java shop. Seriously.

Re: Another long slow decline.
HLASM from IBM is available for z/Linux, and it works very well. Dave Bond sells the Tachyon Assembler, it runs on z/Linux, and also works very well. We are using the Systems/ASM that Dave Rivers sells, and are very happy with it. That's THREE HLASM products that run under z/Linux. :) We had to build a debugger we liked, since we tend to use the debugger during development much more than other shops do. That's partly because we can compile and link a few thousand line programs in two or three seconds, and partly just because that is the way we like to work. Naturally, it is written in assembler - we just captured the signals and linked the debugger in to the applications as a default. Takes a tiny bit more RAM, but since it is self contained, it doesn't affect base register space or anything like that. We are in North Austin. Not all that far away. ;) Thanks for the info on z/VM 5.2 pricing - I was unaware the list pricing had been reduced. -Paul - Original Message - From: Dave Jones [EMAIL PROTECTED] To: IBMVM@LISTSERV.UARK.EDU Sent: Wednesday, November 08, 2006 12:28 PM Subject: Re: Another long slow decline.

Subject: z/VM and SuSE Linux Ver 8
Dear Lists:
Our z/VM and Linux testing goes in
about 6 month cycles. The last time we used SuSE Linux under z/VM, we had z/VM
5.1. We are now using z/VM 5.2 at the 0501 RSU maintenance level.
All of a sudden now (?), we can no
longer connect to our Linux virtual machines using PuTTY. The network guys
tell me that they can see the request going to the z/VM TCPIP address and
being rerouted to the appropriate IP address for the Linux virtual machine,
but there is no response from Linux. With my virtual Linux machine running I
can not PING the z/VM TCPIP stack nor can I ping my Linux machine from the
MAINT virtual machine. When I try to PING TCPIP from Linux, the Linux console
stops working.
Has anyone else had a similar
problem? Have TCPIP parameters changed that much between z/VM 5.1 and
5.2?

That is kind strange, because the new tapes are not yet attached there are two new 3592 TS1120 tape drives ready to connect to the SAN switch and configure. The FiCON port is also ready to connect to the SAN switch and, if necessary, do any configuration. Actually, VM doesn't see the SCSI devices. What it sees are the subchannels on the chpid. In normal ESCON attachment, the control units actively participate in the I/O process. They know which devices are available and which devices are not.For SCSI, there is no traditional control unit to manage device attachment to the I/O subsystem. There's just a cable the plugs into your FC switch. The connection to a particular drive is established dynamically via a specific protocol between the guest or CP and the switch.So as long as the chpid is active, all of the devices you defined on the chpid will appear, but they don't have active devices on them until CP (via EDEVICE) or a guest (via its own SCSI device drivers) does something. Problem is, from this point on I am lost there are WorldWidePort addresses and a lot of other terminology I am not familiar with. So any references or pointers would be very much appreciated.

Re: FLEX-ES and z/VM 4 or z/VM 5
You guys put out some really good points there. We are a midsize company (growing fast!) and we put in a z800, running z/ VM as a hypervisor for Linux, and are porting the business apps over to it. Naturally, we could not do it the way everyone else does it... so it is taking longer than we would like, but the results - ah... they are fantas tic. But the fact that we can do this- and that we do not have to pay signifig ant monthly license costs to IBM, while good for us, is a killer for IBM's ca sh flow. They have not yet learned how to deal with customers our size. For example - when we bought the z, we purchased it on a TSO plan, and paid cash for the Z, Shark, tapes and the whole bundle. We still get thr ee or four invoices per month for it. The money and effort IBM wastes sendin g those out, not to mention the time and effort expended to correct the errors, is astronomical. They could afford it if we were sending them $130K/month in license fees, but ... IBM has to learn how to deal, profitably, with the thousands of companies our size and slightly smaller. They are always shooting themselves in the ir own foot. Another example, when we first contacted IBM about buying a new computer, I told our sales rep we were interested in a mainframe or a pSeries machine , knowing the entire time we wanted a mainframe. They showed up and told us we were too small for a mainframe. grin The truth was they could not find the proper people to sell us the mainframe, and the sales rep they first set us up with was unwilling to do the work to get a proper order placed. He felt that we should simply take whatever he said, at whatever he said the cost was going to be. He also did not think we had any idea what we were talking about using Linux. You don't want to know the stories about the printing people or what the printing people did -- I do believe they wound up disbanding the entire group... (*sigh*) On the other hand, individuals within IBM are some of the greatest people I have ever met. Most of them are truely out there to do the job, and a lot of them are interested in interesting things. What better group of people is there on the planet? I think they are nervous to no end about Hercules, to be honest. I do not think they beleived it could happen, and yet, it has. How can they protec t their revenue source? Restrictive license policies does work, but it als o has the capability of backfiring - people will move more and more to Linu x. And while Linux does not have the same VM capabilities in it as zVM does, that could also change. IBM's greatest nightmare would be people buying j ust zSeries hardware with no software at all. And there is a real possibility that could happen if they don't change their course a bit. And oh yeah, don't forget about the group inside IBM who is still convinc ed that the Mainframe is DEAD, and can be easily replaced with a coulpe pSer ies boxes. Of course that isn't so, but they are loud, vocal, and have just enough truth in their statements to make people listen. -Paul
