Re: VTAM security issue
Itschak Let's see I have got your problem straight. You have two VTAM nodes, VTAMA and VTAMB. There is a CICS application running in each node, CICSA and CICSB. You want to allow CICSA to have sessions with CICSB and you want to prevent all other possible sessions between VTAMA and VTAMB, say from a terminal subordinate to VTAMA, TERMA, in session with CICSB or TSOB and from a terminal subordinate to VTAMB, TERMB, in session with CICSA or TSOA. Let us now go back to the beginning of VTAM time, or actually not quite so far back - the early '70s, before SNA even[1] - but to the late '70s when VTAM got cross-domain function from being purely single domain before - and you had to start paying for it! If you wanted actually to have a cross-domain session you needed to roll up your sleeves and get defining. First of all you needed to arrange that the SSCP of one VTAM could be in session with the SSCP of the other VTAM: In VTAMA's VTAMLST VBUILD TYPE=CDRM VTAMACDRM ISTATUS=ACTIVE,VPACING=63 the home CDRM VTAMBCDRM ISTATUS=ACTIVE,VPACING=63 one of the away CDRMs In VTAMB's VTAMLST VBUILD TYPE=CDRM VTAMACDRM ISTATUS=ACTIVE,VPACING=63 one of the away CDRMs VTAMBCDRM ISTATUS=ACTIVE,VPACING=63 the home CDRM Note how only the comments change; this allows you to use the same definition in all VTAMLSTs - as long as you omit the comments which would now become confusing! Scanning the operands of the CDRM statement today I'm guessing that these two, ISTATUS and VPACING, are the only two available when the CDRM statement was first introduced. On the principle that the default value for an operand represents the behaviour before whatever function introduced with the operand was introduced, we can see that the two important operands to which I want to draw your attention have the following values: CDRDYN=NO[2] CDRSC=REQ[3] The footnotes have the explanations of what these operands actually do. I imagine that VTAM system programmers have been habitually coding CDRDYN=YES and CDRSC=OPT for so long - copied from some redbook sample like as not - that they have forgotten that these operands have these other values with just the effect you want. Thus that's all you need to prevent all cross-domain sessions. Except that with the introduction of APPN in VTAM, CDRDYN got sort-of copied to the start options so you need to make sure that CDRDYN=NO is specified in the start options. But now you need to permit those sessions you actually want. Here's where the hard work used to come in when cross-domain was first available. However for you it's easy since there is only one session you want to allow. In VTAMA's VTAMLST VBUILD TYPE=CDRSC CICSBCDRSC CDRM=VTAMB,ISTATUS=ACTIVE In VTAMB's VTAMLST VBUILD TYPE=CDRSC CICSACDRSC CDRM=VTAMA,ISTATUS=ACTIVE Again, I can't see CDRSC statement operands other than the two I've shown being relevant. QED! And there's no need to reach for your cheque book buying products which offer no function - for you anyhow - other than VTAM provides at no extra cost.[4] If you have other systems, domains, and you want sessions to be established with those other domains with dynamic definition of CDRSCs, you need to be sure that you so specify the CDRM definitions that only VTAMB resources are restricted. For example, you will need to ensure that VTAMB's definition of the VTAMA CDRM specifies CDRSC=REQ in order to prevent TERMA from being defined as a CDRSC within VTAMB and thus is allowed to have a session with CICSB given that CICSB has a CDRSC definition within VTAMA. Chris Mason [1] Not a lot of people remember that! [2] quote Specifies whether the host CDRM is authorized to dynamically define CDRSC representations of cross-domain or cross-network resources when a session request is received from or sent to an adjacent SSCP or CP. CDRDYN=NO Causes the failure of any cross-domain or cross-network session request for a cross-domain or cross-network resource that has no predefined CDRSC entry. CDRDYN=YES Authorizes dynamic definition of cross-domain or cross-network resources by the host CDRM, eliminating the need to predefine certain CDRSCs. Both origin logical units and destination logical units can be dynamically defined. Note that for subarea nodes (HOSTSA start option is specified), the DYNLU=YES operand is meaningful only when CDRDYN=YES. Notes: 1. To allow dynamic resource definition, code CDRDYN=YES on the CDRM definition statement for the VTAM host CDRM and CDRSC=OPT on the CDRM definition statement for the owning SSCP. 2. An intermediate host can also build dynamic definitions for CDRSCs. 3. The CDRDYN start option overrides the CDRDYN operand value. You can use the MODIFY VTAMOPTS command to change the value of CDRDYN. /quote [3] quote Determines whether resources owned by the CDRM being defined by this statement can be dynamically defined at the time a

Re: VTAM security issue
Tony I also want to block the ability to enter logon applid command (may be by userid, even of the solution will require entering userid password). How to achive that? I doubt you can do that with USS, but I may be wrong. Interesting! This would appear to depend on how the LU was defined to VTAM. If a LOCAL statement is used, there is no avoiding the SSCPFM operand specifying SSCPFM=USS3270 (or SSCPFM=USS3275) which implies that Unformatted System Services (USS) commands will always be valid - and interpreted by VTAM's protocol conversion logic for pre/non-SNA channel- attached 3270 devices. These days this support covers OSA-ICC and the like. If an LU statement is used, following VBUILD TYPE=SWNET or VBUILD TYPE=LOCAL for example, the SSCPFM operands could be set to SSCPFM=FSS which should make it impossible to enter USS commands - I would expect although I've never tried it - any volunteers? If SSCPFM=FSS does work as a way to block the use of USS commands, in order to allow the LU to get into session, the LOGAPPL operand will be needed, perhaps to log onto a session manager application if many business applications are to be accessed. Now if you are using the Communications Server (CS) TN3270 server for access to the SNA part of the network, again USS tables can be used. However, if access is restricted with the RESTRICTAPPL statement, even if the USS table is used, the solicitor panel will (also) be used in order to validate the user with a userid and password. Again, this isn't something I've tried but this is what the description of the RESTRICTAPPL statement in the CS IP Configuration Guide tells me in Chapter 10, Accessing remote hosts using Telnet, Mapping methods, Application mapping statements. However, this may not be what Itschak wants since it is checking access in VTAMA for access to CICSB rather than checking access in VTAMB. But there is nothing to say you have to provide a USS screen to your users. Indeed, you need to code up an USS table in order to be able to present an USS message 10. If you don't code up an USS table, you will get the default commands and messages so just not having an USS message 10 has no effect on preventing the entry of a LOGON APPLID(xxx) command. A user just has to have the wit to know that he/she can enter the command even if the emulation window is blank. Actually, if he/she is SNA-3270-savvy, he/she will know to look for a stick man symbol at the lower left of the window or, strictly if the emulation faithfully follows 3270 device behaviour, to press the key combination corresponding to SysReq in order to change the symbol from a question mark to a stick man. That's why I told Itschak before that entry of LOGON APPLID(xxx) cannot be prevented by techniques in coding the USS table. However, fiddling with the SSCPFM operand is something I hadn't considered before! Note that, by coding alternative USS LOGON (and LOGOFF) commands, you do not prevent use of the default commands. It's a bit like ISTINCLM and the MODETAB operand.

I also riched TSO logon etc. Now, I want to block (at) org b ability to get to org a applications other then the CICS connection that was agreed between Org A and B. Is this possible? Sure, but you have to code up a VTAM Session Management Exit (SME). This is described in the SNA Customization book. The summary says The session management exit is a multi-function exit that you can use to control and manage LU-LU session-related functions. You can use the exit to authorize session establishments, obtain session accounting data, and better manage SSCP and GWPATH selection. Coding a basic SME is not too difficult, but getting it to do what you want flexibly is a little harder. You could just hard code the sessions to be allowed, or those to be denied, but then if somone changes the naming conventions, you have a problem. There is at least one commercial product, Blockade For MVS, which has been around for a long time (since 1988), that manages and authorizes SNA sessions in a very flexible way based on RACF permissions, and also provides management of 3270 logons via a session manager.

Because we have so many address spaces in this service class (80+ test address spaces (AS) DB2 - 2 subsystem with 11+ AS IMS - 6 subsystems with 37 AS which includes MPRs CICS - 31 regions) WLM caps all the address spaces, when it gets finished, it is time to uncap them all - then it repeats.

Re: System Install and Catalogs
I never produce a new master cat with a new release install unless there is some compelling reason to do so. My sandbox system has its own master cat so catalog compatibility can be checked there before deploying elsewhere. If you use indirect cataloging for the system resident data sets, the only thing you need to do is indirectly catalog the new ones. Make note of any obsolete ones so you can uncatalog them once 1.9 is production and their is no chance of going back to 1.7. When implementing into a test or production system, the catalog deltas can be applied there. I know you want to avoid human error but the differences are usually small as long as you're not making too large of a jump in releases. If you want to be picky (careful?), I guess some easy Rexx code code be written to compare LISTCAT output. Also, I tend to use a separate catalog for all those system resident data sets that do not start with HLQ SYS1 (eg, CEE). Indirect cataloging works with usercats as well as with mastercats (really no difference). This was made possible by IBM providing a 'volser' parm in link list and LPA list. Just makes for a cleaner master cat. HTH Guy Gardoit z/OS Systems Programmer On Wed, Jan 14, 2009 at 10:39 AM, Matt Dazzo mda...@pch.com wrote: Working on my first system upgrade 1.7 to 1.9.

Re: 2074 configuration problem
If I remember correctly, it is under lan configuration, set route statements, on the 2074 CAx setup menu. I believe the default entry is for the gateway. I think this is what you would need. route -fh route add default 10.10.10.251 -hopcount 1 route add -net 10.10.10.251 -netmask 255.0.0.0 -hopcount 1 Just use your own IP addresses. I am not 100% sure as I use explicit routing to my PCs and the gateway is the second entry on the route statement. It is the only way I can limit access to the 2074s.

Re: VTAM security issue
Itschak I see you are there and able to respond. Since we haven't heard a Thanks Chris that exactly meets my requirements. I must assume that my purely VTAM solution using CDRM statement operands and CDRSC statements where necessary didn't somehow answer your needs. I'd rather like to know why since it's so straightforward. And, of course, I'm still trying to have you avoid any unnecessary expense! So let's try again from the beginning. CICS of organization A is connected (LU6.2 Connection) to CICS of organization B. No problem with that. Translation: There is a CICSA-CICSB set of sessions. (being LU 6.2 it will be a set of sessions rather than a single session.). Whatever measures are taken to prevent other sessions being established need to allow this set of sessions to be established. I looked into the CDRM and found some other application (probably plural applications) of organization B defined in VTAMLST of oranization A. Translation: I browsed the CDRSC (CDRM was corrected in a following post to CDRSC) major node VTAMLST member or members in the VTAMA VTAMLST library and found other CDRSC statements presumably corresponding to other applications, some of them other CICS applications. (The fact some were other CICS applications is mentioned in a following post.) Tried LOGON APPLID(xxx) and gpt the GMtran of org. B (if it is the default, I can travel in this CICS...). Translation: I succeeded in logging onto one or more CICS applications in VTAMB, CICSB, CICSB1 ..., using the names I found in the CDRSC statements and I was presented with the Good Morning messages. Assuming there is no CICS-level security imposed, I can enter transactions in these CICS applications. I also riched TSO logon etc. Translation: I also succeeded in logging onto the TSO application in VTAMB, TSOB, as far as the logon panel. And I succeeded in logging onto other applications. Now, I want to block (at) org b ability to get to org a applications other then the CICS connection that was agreed between Org A and B. Translation: Having seen what I can do as a user associated with VTAMA in accessing applications in VTAMB, I am concerned that a user associated with VTAMB can access applications in VTAMA, the VTAM with which I am working. I want to prevent a user associated with VTAMB accessing applications in VTAMA. Is this possible? Translation: None needed! Answer: Assuming you have the authority to change VTAM definitions, in the VBUILD TYPE=CDRM member in VTAMA VTAMLST, change the VTAMB CDRM statement to specify CDRSC=REQ and do *not* define any of the end-user LUs associated with, owned by, VTAMB as CDRSCs. That way none of the VTAMB end-users can initiate a session with any of the VTAMA applications - exactly what I think you want to achieve. In order still to be able to set up the CICSA-CICSB sessions, you will need to define a CDRSC in VTAMA for CICSB as CICSB CDRSC CDRM=VTAMB within a VBUILD TYPE=CDRSC member. Hitherto, I expect this CDRSC will have been defined dynamically because you specified CDRSC=OPT for VTAMB and CDRDYN=YES is in effect for your local CDRM. Walt, these are not just pointers, this is chapter and verse! To continue: I also want to block the ability to enter logon applid command (may be by userid, even of the solution will require entering userid password). How to achive that? Answer: Presumably you are talking about blocking the use of LOGON APPLID (xxx) at VTAMB for the VTAMA applications. When stated like that, this is clearly undesirable since it would prevent end-users in VTAMB accessing applications in VTAMB! Also, unless that trick of using SSCPFM=FSS works and that value can be applied to the VTAM definition, there is no way actually to prevent the use of the default USS LOGON and LOGOFF commands. If the end-users in VTAMB access SNA by means of a TN3270 server, then use of RESTRICTAPPL can impose use of a userid and password as described in the Communications Server IP Configuration Guide. What other alternatives are offered to connect to vtam applications when USS tab is displaied, other then LOG APPLID and selecting from the uss tab? I mean, is there any bypass to LOG APPLID if blocked? Translation: What other alternatives are offered to connect to VTAM applications when USS message 10 is displayed other then LOGON APPLID(xxx) *or* selecting from LOGON command aliases defined in the USS table? I mean, is there any bypass to LOGON APPLID(xxx) if blocked? Answer: Use of the interpret table can, in effect, bypass the use of commands defined in the USS table. The usual alternative to use of USS LOGON commands in order to initiate sessions from end-user LUs is to use a session manager with which a session is established by means of a LOGAPPL operand on the LU (or LOCAL) statement definition. - Now, there is no way to stop some one in org A to simply logon to org B CICS. Answer: Oh yes there is - see above.

Re: VTAM security issue
John, Do you want me to surprise you? As your new president said: yes, we can. Sec=YES has nothing to do with the signon procedure of CICS and how users get identified. As you know, each terminal runs the dfltuser (from SIT) if no user signed on. Its is well documented in the manuals. This is where I start when doing Pentest.

The only limit I have when Pentesting is the partner company to agree for the signon. I have seen few sites using no GMTRAN at all, so you signon to CICS with no password and get the default user auth! There are also few other VTAM applications that uses internal userid and passowrd that is stored in a file. NDM is a sumple for super user that is described in a parameter library. It is not possible (without some exit programming) to sign on to CICS without tendering both a user ID and a password. If a CICS region is started with DFHSIT parameter SEC=NO, then CICS itself rejects _any_ sign-on attempt (i.e., you cannot sign on at all); you're in (as the default CICS user) by virtue of having connected, and can execute any transaction defined in that region. At the VTAM level, you cannot prevent connecting to a foreign CICS except via requiring explicit CDRSC definitions, as others have already noted. Otherwise, if your VTAM can find the requested CICS, a session will be established (i.e., you will be connected). At the CICS level (i.e., once you are connected to CICS), access to the CICS region itself can be controlled via a RACF APPL profile, but that authorization is not (cannot be) checked until sign-on is attempted. This requires that CICS be started with DFHSIT parameter SEC=YES, at minimum. -jc- -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

Since I´m no an expert in cobol or other programm language and in Linux
plataform, my questions are:
There is any open source software or not that can read this record and
resolve comp-3 fields?
I am not aware of any package which will do that, if this is what you mean.
COMP-3 fields are packed decimal. It is rather easy to convert these into
an integer. The number of bytes that are taken for a PIC S9(n) COMP-3 field
is (n+2)/2 and ignore the remainder. E.g. PIC S9(1) COMP-3 is 1 byte. PIC
S9(2) COMP-3 is 2 bytes, as is PIC S9(3). And so on. Now, if there is no S
in front of the 9, then the data is forced to be positive.
Some C code which can convert from COMP-3 to int:
int toint(unsigned char* packed, int digits) {
int bytes=(digits+2)1;
int n=bytes-1;
int i,j;
int result=0;
for (i=1;in;i++) {
result=100*j+10*(*packed1)+(*packed 0x0f);
packed++; /* examine next byte */
}
result=10*result+(*packed1);
i=*packed 0x0f;
if (i==11 || i==13) result=-result; /* negative sign */
return result;
}
If no software availalble, any one has a sample how to read this record
using any linux plataform language?
I've used Java to do something similar. I must assume that you already know
how to read the file on tape. I don't know how to do that. But assume that
the variable tape is the open()'ed FILE *. You must read every record
yourself. This will be a bit complicated because the file is variable
blocked. That means that every physical tape record consists of a BDW (Block
Descriptor Word), followed by one or more logical records. Each logical
record is prefixed with a RDW (Record Descriptor Word). My, this is getting
complicated. The following C code should perhaps help. But I cannot test it
(the same as the above).
#include stdio.h
#include string.h
#include stdlib.h
static char buffer[32768];
static int buf_off=32768;
static int block_length=0;
static int record_length=0;
size_t doread(char *record, FILE *tape) {
unsigned char bdw[2];
if (buf_off = block_length) {
block_read:;
fread(bdw,2,1,tape); /* read the block descriptor */
block_length=bdw[1]8|bdw[2]-4;
fread(bdw,2,1,tape); /* read and skip 2 bytes */
if (block_length0) {
fread(buffer,block_length,1,tape);
} else goto block_read;
}
record_length=buffer[buf_off]8|buffer[buf_off+1]-4;
buf_off+=4;
if (buf_off+record_lengthblock_length) return -1;
if (record_length0) {
memcpy(record,buffer+buf_off,record_length);
}
return record_length;
}
Note that the above copies the current logical record into your memory area.
It also returns the length of the amount of data copied. The length could be
zero. If the routine returns a -1, that means that there is a problem with
the file (or a bug in my code).
Thanks for comments and hints.

It simply does not get into maximum/minimum issues for things like this.

Re: VTAM security issue
Itschak I looked into the USS TAB code and found that a I can force some input rules, ;like blocking LOG APPLID. Actually you can't! Recall I said it was a bit like ISTINCLM and the MODETAB operand. You always have the mode table entries in ISTINCLM even if you code a MODETAB operand. Similarly, you always have the default USS commands LOGON, LOGOFF and IBMTEST even if you code an USS table. Here is a paragraph from Customizing USS tables in Unformatted system services (USS) tables in Chapter 5, User-defined tables and data filter in the Communications Server SNA Resource Definition Reference manual: quote Any changes to VTAM messages or commands should be made with supplementary user-defined USS tables. The IBM-supplied USS tables should not be changed or removed since they are used to define all commands and messages that are not defined in a user-written table. The name of the user- defined USS table should be different from any of the default tables. /quote So, actually, I guess you could clobber the default commands by redefining ISTINCDT but you are really not supposed to do that! You might affect IBM's willingness to support you if you do clobber ISTINCDT. You might like to read through my earlier responses again - slowly - since I have made this point about not being able to suppress the LOGON command before. In any case, now that you know about redefining your CDRM statements and introducing the bare minimum of CDRSC statements, you don't need to worry about USS commands.

The differences are EBCDIC vs ASCII, big endian vs little endian, the joys of comp-3 and the ever present joys of character stream IO vs z/os record handling. I do not know of any utility that will handle these changes automatically. As described by others, it can be done on a pc, but it is by no means simple or easy. The best answer is to build a utility job on the main frame that will expand all numerics to character fields. You could even do the ascii conversion ( I know DFSORT can do all the above conversions - I am not as fast or accurate as some others but some quality time with the manual will get you there).

The bottom-line (as others in the thread have hinted at) is that it is
difficult (not impossible) to convert both numeric and character data in
one pass. If any of the numeric data is in other than display,
sign-is-separate format (Zoned Decimal in IBM mainframe speak) it becomes
more difficult.
There are lots of tools (none that I know of that are free) that can do
this, but the reason they are complex (and cost money) is that in the case
of records with mixed numeric (packed, binary, floating-point) and character
data, the conversion routine must be able to understand every record in
the file. In cases where all records have the same layout AND the records
are fixed length, then a simple COBOL program can be created to do this.
(The COBOL can run on the mainframe, on Linux, on Windows - wherever you
have a COBOL compiler).
In cases where there are variable length records and multiple record layouts
within the same file, then INTELLIGENT conversion is required. Each record
must be matched with its correct layout and character data must be
converted (EBCDIC - ASCII) and numeric data handled correctly
(big-/little-endian, IEEE vs HFP, packed-decimal sign-nibbles, etc).
***
The simplest universal solution (which is almost never possible G) is to
get whoever creates the file to define all numeric fields with the COBOL
USAGE DISPLAY SIGN IS LEADING SEPARATE
(and of course don't use any Unicode or DBCS character data)
When this is done a simple ASCII - EBCDIC conversion of the entire file
will solve everything.
When this can't/wont be done, then you MUST get the COBOL record layout or
layouts and depending on how complex they are, either create a one time
conversion program (in COBOL) or purchase a tool that will do it for you.

Hi Listers, (xposted to VSE-L and OS/390 List)
I need to read an IBM 3490 cartridge recorded by OS/390 program in a
Linux system. If this works fine in intel server, I can migrate it to
Linux under mainframe later.
I have a 3490-E01 (scsi interface) connected to an IBM x236 system.
Until here no problem.
Tape has a record type of VB (126-1295) and some fields into record are
defined as PIC 9(xxx) comp-3. I got this from mainframe cobol program,
since today
I read it in our mainframe system, using a cobol program. (read tape and
write a pds file)
Since I´m no an expert in cobol or other programm language and in Linux
plataform, my questions are:
There is any open source software or not that can read this record and
resolve comp-3 fields?
I am not aware of any package which will do that, if this is what you
mean.
COMP-3 fields are packed decimal. It is rather easy to convert these
into
an integer. The number of bytes that are taken for a PIC S9(n) COMP-3
field
is (n+2)/2 and ignore the remainder. E.g. PIC S9(1) COMP-3 is 1 byte. PIC
S9(2) COMP-3 is 2 bytes, as is PIC S9(3). And so on. Now, if there is no S
in front of the 9, then the data is forced to be positive.
Some C code which can convert from COMP-3 to int:
int toint(unsigned char* packed, int digits) {
int bytes=(digits+2)1;
int n=bytes-1;
int i,j;
int result=0;
for (i=1;in;i++) {
result=100*j+10*(*packed1)+(*packed 0x0f);
packed++; /* examine next byte */
}
result=10*result+(*packed1);
i=*packed 0x0f;
if (i==11 || i==13) result=-result; /* negative sign */
return result;
}
If no software availalble, any one has a sample how to read this record
using any linux plataform language?
I've used Java to do something similar. I must assume that you already
know
how to read the file on tape. I don't know how to do that. But assume that
the variable tape is the open()'ed FILE *. You must read every record
yourself. This will be a bit complicated because the file is variable
blocked. That means that every physical tape record consists of a BDW
(Block
Descriptor Word), followed by one or more logical records. Each logical
record is prefixed with a RDW (Record Descriptor Word). My, this is
getting
complicated. The following C code should perhaps help. But I cannot test
it
(the same as the above).
#include stdio.h
#include string.h
#include stdlib.h
static char buffer[32768];
static int buf_off=32768;
static int block_length=0;
static int record_length=0;
size_t doread(char *record, FILE *tape) {
unsigned char bdw[2];
if (buf_off = block_length) {

Re: Some kind of hint!!!
The JZOS Toolkit has a set of classes that will act as field converters for all of the COBOL and Assembler datatypes. You can download a version from alphaWorks and run these on not only z/OS, but PC. Also on the JZOS alphaWorks site is a tool that will convert a COBOL copybook (or Assembler DSECT) into a Java source class that will map an entire record of fields. This tool requires that you compile the COBOL copy book using the z/OS Enterprise COBOL compiler and generate an ADATA file. The Java tool will use the ADATA file to build the Java source code. You can run the generator tool either on the mainframe or on a PC (if you download the ADATA file). There are examples in the latest JZOS Cookbook (available from the same alphaworks JZOS page), including nifty Ant scripts that generate and submit JCL generate the classes, run the examples, etc. To run the code on a PC, you would need to download the binary records from z/OS (or in your case, a tape). If the records are variable length, then you will want to preceed each record with RDWs. There is example code in the Cookbook that shows how to read a binary RDW-prefixed file on the PC and process the records mapped with a Java class generated from a COBOL copy book. If you have questions on the tools or the Cookbook, feel free to ask then on the JZOS alphaworks forum. See: http://www.alphaworks.ibm.com/tech/zosjavabatchtk FWIW - the run-time field converter classes are now part of the version of the JZOS Toolkit that is shipped with the z/OS Java SDK. So, there is no reliance at runtime on unsupported alphaWorks tools (the code generated by the alphaWorks-only tool is yours).

Re: System Install and Catalogs
I never produce a new master cat with a new release install unless there is some compelling reason to do so. My sandbox system has its own master cat so catalog compatibility can be checked there before deploying elsewhere. If you use indirect cataloging for the system resident data sets, the only thing you need to do is indirectly catalog the new ones. Make note of any obsolete ones so you can uncatalog them once 1.9 is production and their is no chance of going back to 1.7. When implementing into a test or production system, the catalog deltas can be applied there. I know you want to avoid human error but the differences are usually small as long as you're not making too large of a jump in releases. If you want to be picky (careful?), I guess some easy Rexx code code be written to compare LISTCAT output. Also, I tend to use a separate catalog for all those system resident data sets that do not start with HLQ SYS1 (eg, CEE). Indirect cataloging works with usercats as well as with mastercats (really no difference). This was made possible by IBM providing a 'volser' parm in link list and LPA list. Just makes for a cleaner master cat. HTH Guy Gardoit z/OS Systems Programmer ---SNIP-- Guy: Interesting way of doing things and probably OK for most. What I did (little different than you) is that I really got upset at IBM for coming up with foreign names like CEE (and a few others) what I did was to rename those datasets that are really needed to sys1. Now came the fun part deciding which datasets needed to be renamed, what I did especially for cee and the stupid TSO products which I personally never used and no one I ever ran into used was to again rename them sys1 and not catalog them. We had a rule (RACF) also forbidding anyone from accessing any sys1 type datasets except specified ones like sys1.help and a few others. That RACF rule kept life simple for me a sysprog. No need to worry about cataloging datasets except new ones that needed to be handed out (very few in 10+ years if any). I didn't need to maintain the mastercat (except for a few here and there) The good side also that I hardcoded volsers in my SMP/e Proc (and in the smpe zone)and it worked reasonably well. I never got to the issue of HFS's but I think off the top of my head I would have put a rule in RACF again for no user access and the only issue might be in applying maintenance so I am not sure at the moment how I would have addressed that. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: C without LE [was: RE: VSM Changes in z/OS 1.10: Beta Systems Software]
Barbara, I was looking at your reply and after a few hours this company rang a small bell in my head.

I think (I really could be off in this) that it was a product from Europe and I couldn't get it running for anything. My memory is poor but I think we had a vaguely similar issue but it was with LE and the product. They were (probably) shipping LE modules with their product and of course when you relinked the modules they wouldn't because of LE issues (module name changes??). Sorry its been years and my memory is vague here. I really got pissed because of this and I wrote a two page report to my boss taking the product to task for shipping LE modules with their product. We turned down their product because of that. I can only remember it was from Europe and had a dickens of a time because their doc was in A4 (page size) format and it was hell getting it converted to the US size.
