Re: [E!] Re: Re: Automatic Alias Creation
Sasan,
In this case, you will need to write a "Post-Operation Plug-In" for the IBM
Tivoli Directory Server.
This plug-in can be architected to recognize an "ADD" operation (i.e.,
"ADDUSER" in RACF terminology).
It can then check for the existence of an ICF catalog alias, and if found, then
exit with no further action required.
If not found, it can then issue a START STC command to run a REXX PROC (i.e.,
"ICF Catalog Alias Creation STC") which in turn invokes IDCAMS to define the
ICF catalog alias.
The Tivoli Directory Server STC will require the authorization to start the STC
(i.e., "UPDATE" access to resource ID "MVS.START.STC.{std-id-8}" in resource
class ID "OPERCMDS").
The ICF Catalog Alias Creation STC will require the authorization to define the
ICF catalog alias (i.e., "READ" access to resource ID
"STGADMIN.IGG.DEFDEL.UALIAS" in resource class ID "FACILITY").

Hi John,
SailPoint IIQ has 2 different connectors. The RACF connector (which has the
CTS STCs you mention) and the RACF LDAP Connector which uses the SDBM
backend. We've implemented only the LDAP Conncetor. The LDAP connector uses the
IBM Tivoli Directory Server which is included with z/OS. The SDBM backend
allows us to make all types of RACF definitions, however I don't think it
allows us to issue TSO commands. I've looked at the documentation and there is
nothing there. I've also looked to see if there are any exits available and
haven't found anything there either ☹

The "CTSx" STCs will need to have the requisite "READ" access to resource

That's actually what we've been doing for a long time. Our Sec admins use ISPF
interface to make all RACF/TSO definitions. We will soon be using a new product
to provision RACF IDs called Sailpoint IIQ. IIQ uses LDAP Server to provision
RACF IDs and that will most likely be done by Helpdesk or other users who have
little knowledge of RACF and TSO.
We have to figure out a way to automate the ALIAS creation process when a RACF

Hi list,
We're currently provisioning RACF IDs using the Tivoli Directory Server (LDAP
SDBM backend). For IDs that are defined with TSO segment we need to figure out
a way to automatically create an ALIAS. What would be the best way to go about
this? I've thought about doing it in our LOGON PROC, however that would require
users to have UPDATE access to the master catalog which we would like to avoid.
How else can we go about this?

Re: Vector processing instructions
Amrith, Converting a 128-bit unsigned fixed binary integer to packed decimal is not particularly difficult. The following methodology should meet your needs - IVFB - Input Value (128-bit Unsigned Fixed Binary) WVFB - Working Value (128-bit Unsigned Fixed Binary) AFPD - Adjustment Factor (11-byte Packed Decimal) QUFB - Quotient (64-bit Unsigned Fixed Binary) RMFB - Remainder (64-bit Unsigned Fixed Binary) QUPD - Quotient (11-byte Packed Decimal) RMPD - Remainder (10-byte Packed Decimal) OVPD - Output Value (20-byte Packed Decimal) WVFB = IVFB ; AFPD = 0 ; Do While (WVFB >= 100) ; /* (10**38) */ WVFB = (WVFB - 100) ; /* (10**38) */ AFPD = AFPD + 1000 ; /* (10**19) */ End ; Do While (WVFB >= 9223372036854775807000) ; /* ((2**63) - 1) * (10**19) */ WVFB = WVFB - 10 ; /* (10**37) */ AFPD = AFPD + 100 ; /* (10**18) */ End ; QUFB = WVFB / 1000 ; /* (10**19) ; Remainder in "RMFB" */ QUPD = QUFB ; /* Convert to Packed Decimal */ RMPD = RMFB ; /* Convert to Packed Decimal */ QUPD = QUPD + AFPD ; OVPD = QUPD (20 digits)) || RMPD (19 digits) ; Please note than in the last pseudo-code instruction, the 19 digits of RMPD + the sign field fill ten (10) bytes. However, the sign field of QUPD must be ignored, so an MVO instruction can be used to shift the value one (1) nibble to the left. The QUPD value (after discarding the rightmost byte) can be appended to the front of RMPD, giving you a 30-byte packed decimal value. Please note that a packed decimal field of this length is NOT supported by IBM machine instructions except (I believe) for the ED/EDMK instructions ( I have not tested this). The logic for converting a signed 128-bit value is slightly more complex, but is also do-able without any significant difficulty. John P.

You can probably do this in one command by using the output of 'find' as

Re: BPXWUNIX and sort
Kirk, The following example illustrates what I am trying to do -- Call BPXWUNIX "sort -k 3 -k 4 -k 1 -k 2", table_in., table_out., messages_out. ; In the above example, "table_in." in a stem variable containing the rows to be sorted, "table_out."

The "-k n" parameters indicates the space/tab delimited fields which are to be used as sort keys. The problem that I am experiencing is that the data is being sorted using the ASCII collating sequence (i.e., numerics precede alphabetics). Which I get the table back, "B12" precedes "BBB". This makes the subsequent binary search subroutine fail since as far as it is concerned, the rows contained in stem variable "table_out." are not sorted. There is an optional fifth parameter (another stem variable) which allows environmental variable settings to be passed. I tried setting LC_COLLATE to no effect.

Re: Volkswagen Programmed Vehicle to Deactivate Pollution Control Systems
Scott, I agree that ethics is a large part of it. I will suggest that it is reasonable to anticipate that an attorney may well argue that the programmers in fact became co-conspirators by virtue of the fact that they cannot reasonably argue that they did not know that the code was intended to perpetuate a crime. Whether that argument is made in this case or in some future case, I strongly believe that at some point it will be made, and that it is more likely to occur sooner than later. I suggest that it would be better for the programming profession to take proactive steps to come up with ethical guidelines for members of our profession, rather than leaving it to government to do it, which as we all know, would not be in our best interests.

Re: COBOL packed decimal
Phil, In the IBM z/Architecture Principles of Operation, publication number SA22-7832-08, on page 8-2 it states that X'F' is an alternate encoding for a positive sign. However, in the programming note to figure 8-1 on page 8-3, it suggests that X'F' be used in zoned decimal formats for the high-order nibble of all bytes save the rightmost, which should be encoded using one of the recognized sign encodings. I would note that if the value is nonnegative, an encoding of X'F' is preferable to X'C' in that in the zoned decimal format, the resulting character string consists of all decimal digits. It is worth noting that the PACK machine instruction does NO validation of the sign nibble in any byte of the field being packed. The sign nibble of the rightmost byte of the source (zoned) field is copied to the rightmost nibble of the target (packed) field. John P.

Re: COBOL packed decimal
Bernd, I can't agree that mainframe applications are more stable because of packed decimal arithmetic. Rather, I would argue that mainframe developers generally have a philosophically different approach to software development than distributed/workstation developers. In particular, I would argue that they generally take more time, both in the development process and in the code review process, and that this additional time is what makes the difference. By the way, a 5-byte field capable of containing a 9-digit packed decimal value has a 0.55% probability of containing a valid packed decimal value (taking into consideration all six (6) valid sign representations) and a 0.18% probability of containing a valid packed decimal value (taking into consideration only the two (2) preferred sign representations).

With packed decimal data, the probability that the use of an un-initialized variable will lead to a run time error (0C7 abend) is very high. Take a nine digit decimal variable - the probability that it contains a valid decimal representation if all bit patterns have the same probability is not very high (0.1 percent). With all binary data types, all bit patterns are valid, and you have no chance to detect the use of an un-initialized variable (the german Telefunken hardware had tag bits in storage which allowed for the detection of such errors even in the binary case - the storage was initially tagged with a "strange" data type, and so the hardware produced a so-called "Typenkennungs-Alarm"). I believe that most of the rumour that mainframe applications are more "stable" than applications on other platforms comes from this property of the decimal data type, and from the fact, that most applications are written in COBOL and use this data type, so that such errors are detected during testing stage. The more decimal data you have in your applications, the more stable are your applications. This could also be one of the reasons for the programming language C being not so stable (among others, like pointer arithmetic, no control of subscripts etc): the absence of decimal arithmetic in C - normally. I'm not sure, if I told you already: in our shop, we run the PL/1 applications in production with SUBSCRIPTRANGE enabled since some years ago, and we are very happy with this. The performance is acceptable. Kind regards Bernd -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
