[snip] How do I specify LARGE_FILE_SUPPORT in my compile What follows is based on the information in the INSTALL file in the zip31b directory. This may not work, but it's the first step to try. It looks like the configure script (invoked from the Makefile) failed to detect that your OS can handle large files. Try the following to coerce make into setting the LARGE_FILE_SUPPORT and ZIP64_SUPPORT options. When you ran make, it should have left a file called flags in your zip31b directory. You need to edit this - it's one long line with all the complier/linker flags. Look for the CFLAGS string - it should look something like this: CFLAGS=-I. -DUNIX -O3 ... ... ... and add -DLARGE_FILE_SUPPORT to this string. Then re-run make, and see if it builds without errors. Try to run zip to see if it works. Enter zip -v, and check what special options it says it was built with. Try to zip a small file. If zip reported that is was built with ZIP64_SUPPORT - which should be set automagically if you specified LARGE_FILE_SUPPORT - then you are ready to try a large (2GB) file. If no ZIP64_SUPPORT, go back and edit the flags file again. This time add -DZIP64_SUPPORT to the cFLAGS string. Run make again. If it builds, try zip out on a small file again, then on a big (2GB) one. If you got compile/link errors after forcing these options, or if it built OK but still fails, let us know what errors you got, and on which step you got them. Oh, and you might try posting that info to the Info-ZIP forum also. as well as make use of the MVS dataset name format ie. -MV=dots ?? It was unclear to me from the forum whether the -MV=dots argument made it into the 3.1 beta. Did it? Has anyone got this part to work or tested on z/OS ?

Re: CL/Supersession and APPN
John I'm glad you've got over the problem. It might be best if each specific problem is presented, sense codes and all. is what I said last time. I am very well aware of the problem which is solved by specifying a value for the APPNCOS start option. Why? Because I had to solve the identical problem myself a few months ago - actually - and you may find some encouragement in this - the *only* problem that I had to solve in the migration. Incidentally, the product just happened to be NetView FTP trying to set up a session with another NetView FTP with the problem showing itself when there was an attempt to set up a file transfer. The reason you - for now - solved your problem by specifying the APPNCOS start option is that you - or some predecessor - had a rush of blood perhaps long ago and actually set up a private mode table entry with a subarea COS name - having first, of course, set up a subarea COS table and stored it in VTAMLIB. If one's assessment of a customer site is that they are unlikely to have been sufficiently adventurous to establish COS entries - as it was in my case having seen some private mode table entries which lacked COS operands - it doesn't seem necessary to worry about the APPNCOS start option. Another excuse not to have changed the APPNCOS start option value from NONE, the default, to something like #CONNECT, is to leave a trap for just the problem about which we would have read had you actually described your problem in detail. Having detected such a problem the change to the private mode table entry could then be made in order to ensure that an APPNCOS operand was added which had the same significance as the existing subarea COS operand. I could guess that the subarea COS operand that caused your problem mapped to a virtual route number which you - or your predecessor - intended always to be used for interactive traffic - I'm relying here on the fact that the application was Supersession - and also to a transmission priority of 2, the highest of the subarea transmission priorities. All that being so, I would advise that you locate the offending private mode table entry in the source of the private mode table - wherever it is! - add an appropriate APPNCOS operand such as #INTER, assemble and linkage edit the table overriding the existing mode table in your VTAMLIB. You can then reset the APPNCOS start option to NONE ready for the next similar problem - with which you now know how to deal. Let's see if I can reconstruct the problem you were having - and what you should have presented as your problem. If I remember correctly, we first had to track down a log of the VTAM where the problem in the NetView FTP was manifest and check messages at the appropriate time. There was one of those message sequences where the SSCPs tried in the subarea serial search are listed with the sense code returned from each. One of the SSCPs, a pseudo-SSCP, was ISTAPNCP which indicates the point at which the search entered the APPN part of the network at that particular VTAM node. The sense code returned was 80140002, essentially, APPN COS not found. This was caused because there was a(n unexpected) subarea COS specified as COS=WHATEVER on the MODEENT macro for the mode table entry used by NetView FTP. Since there was no APPNCOS operand specified on the MODEENT macro for this mode table entry, VTAM obliges itself to assume that the name to use for the APPNCOS operand is the same as the name used for the COS operand.[1] Since there is no APPN COS table entry WHATEVER, VTAM is about to give up when it remembers there is one last chance, namely the name specified in the APPNCOS start option put there as what in English schoolboy cricket is the long stop fielding position for when the wicket keeper makes a mess of things - he might be excused as a very fine third man if the title long stop was considered too undignified!

Checking now with the description of the APPNCOS start option, I see that the manual authors also warn against relying on this start option: quote If a requested Class of Service cannot be found, the value you specify in APPNCOS is substituted for it, and there is a possibility that the characteristics of the substitute Class of Service are not the ones you intended for the route. For example, a secure Class of Service might have been intended, but the

Re: CL/Supersession and APPN
Chris, Your assessment is correct. We have private mode tables built without the correct COS parameters. We will go through the process of cleaning up our old definitions and add the proper COS definition so we don't rely on the default APPNCOS start option per your suggestion. Thanks for the advice.

It might be best if each specific problem is presented, sense codes and all. is what I said last time. I am very well aware of the problem which is solved by specifying a value for the APPNCOS start option. Why? Because I had to solve the identical problem myself a few months ago - actually - and you may find some encouragement in this - the *only* problem that I had to solve in the migration. Incidentally, the product just happened to be NetView FTP trying to set up a session with another NetView FTP with the problem showing itself when there was an attempt to set up a file transfer. The reason you - for now - solved your problem by specifying the APPNCOS start option is that you - or some predecessor - had a rush of blood perhaps long ago and actually set up a private mode table entry with a subarea COS name - having first, of course, set up a subarea COS table and stored it in VTAMLIB. If one's assessment of a customer site is that they are unlikely to have been sufficiently adventurous to establish COS entries - as it was in my case having seen some private mode table entries which lacked COS operands - it doesn't seem necessary to worry about the APPNCOS start option. Another excuse not to have changed the APPNCOS start option value from NONE, the default, to something like #CONNECT, is to leave a trap for just the problem about which we would have read had you actually described your problem in detail. Having detected such a problem the change to the private mode table entry could then be made in order to ensure that an APPNCOS operand was added which had the same significance as the existing subarea COS operand. I could guess that the subarea COS operand that caused your problem mapped to a virtual route number which you - or your predecessor - intended always to be used for interactive traffic - I'm relying here on the fact that the application was Supersession - and also to a transmission priority of 2, the highest of the subarea transmission priorities. All that being so, I would advise that you locate the offending private mode table entry in the source of the private mode table - wherever it is! - add an appropriate APPNCOS operand such as #INTER, assemble and linkage edit the table overriding the existing mode table in your VTAMLIB. You can then reset the APPNCOS start option to NONE ready for the next similar problem - with which you now know how to deal.

I appreciate the reference. That pain medication industry owes you one. ;) From what I've read so far, it appears that this only applies to the TCPIP stack on which the policy is managed. Since z/OS is not the bottleneck, my guess is that the effect of setting up the appropriate QoS stuff on z/OS will be of no benefit to the affected CIP router. In fact, to make matters worse, the CIP router is connected to two z/OS systems, one of which has the onlines, and the other the batch work.

Re: Any products to protect MVS software from cracking and reverse engineering?
I am not endorsing or recommending that vendors take extra steps to obfuscate code, nor am I endorsing any particular products. However, that said, I am answering the original poster's question directly. There are a number of such products. Each tends to be focused on a specific programming language. Here are a few examples. 1. There are many obfuscators for Java. Just use Google or a comparable search engine to find Java source code protection and you'll see a bunch pop up. Most if not all of those should be entirely applicable to Java deployments to z/OS and to Linux on System z. 2. There are also obfuscators for C/C++ which probably are highly relevant to both z/OS and Linux on System z. Stunnix, for example, produces a cross-platform obfuscator that turns original, maintainable C/C++ source code into hard-to-maintain (but still compilable) C/C++ source code. There are other companies that produce similar tools. 3. IBM's REXX Compiler does not *paticularly* obfuscate code, but recipients of the compiled REXX code have to work slightly harder to extract some kind of source. These compiled REXX programs can run using the licensed library or the no charge Alternate Library for REXX, so they can run on all z/OS machines. 4. For COBOL, Redvers offers an obfuscator: http://www.redversconsulting.com/cloaking_device.php 5. The Redvers obfuscator probably also works as an intermediate step with the Rational Enterprise Generation Language (EGL) deployment choices to IBM Language Environment, if you're working with EGL.

Re: Any products to protect MVS software from cracking and reverse engineering?
HI, I found two points which I can address to have some protection in assembler code. 1, Disable slip per - I investigate some zos structure and find out the structure which are use to describe the slip. This is important because disable slip, which is not tracing your code is unacceptable. Also slip without instruction fetch are legal for your code as well to be able to debug problems in your code. I thing that the best solution if this is the case is to change the slip action from action=TRACE to action=IGNORE only if the slip action is trace (ACTION=TRACE) and the job name/asid is specify your job. is your job name/asid. 2. Disable debugging using software which use SVC for breaking points (for instruction tracing) - SVC can not be used if you are SRB or Some SVC types. The easy solution is to use MVS lock. SVC is also does not allowed in code which is locked (using setlock macro). I think that the best solution is to setlock in sensitive code range to disable tracing sensitive instructions which does not issue any SVC or long time instruction. Is it danger to use setlock if it is not needed?. Not at all if you will use setlock type=local for one time running sensitive code (Checking and comparing the encripted serial or other important code). My question, if the way I see the solution is acceptable? BTW, if you like to see, example of code (for per, action=ignore) I consider to use to have some protection to my code, I can do it.
