Re: Not mainframe but the latest in the TJMax fisaco

Re: RMM Discrete profiles
Here's what I received from the security group regarding BLP. If your system supports BLP processing, RACF provides installations with the ability to control the use of the BLP option on JCL DD statements. To control who can use BLP, take the following steps: 1. Activate the TAPEVOL class. 2. Define a profile in the FACILITY class to protect the ICHBLP resource, and grant users READ or UPDATE authority, as appropriate.

Re: FEKFRSRV Service Class
Two possibilities that I can think of (perhaps more) ... The FEKFRSRV task is not really an STC, but a (1) APPC task of a (2) USS task. In case (1), this task name should be placed in the ASCH subsystem entry under WLM option 6. In case (2), this task should be placed in the OMVS subsystem entry under WLM option 6. IMHO, nothing should ever run with SYSOTHER, which you are correctly trying to fix. Everything should be well known, and classified accordingly.

Re: Not mainframe but the latest in the TJMax fisaco
I guess a security mind-set is necessary at appropriate levels of the organization, and this organization appears to have had no such mind-set. BACK patting Back in the mid 90's I designed and wrote a small system for one of the brokerage houses. This system replaced the then current method of getting trades from the brokerage house to a custodian bank, to process the financial aspects of the trade, via FAX. (they actually had a room full of fax machines and a small staff that did nothing but fax trade orders to custodians banks around the world as they came off the printers). Anyway, part of my design included 128 bit encryption security measures and the key changed with each transmission to each custodian bank. If things got of out sync, and they did on occasion (we were using Windows after all), it required human intervention on both ends. When I presented the original design, I had to convince some staff members of the importance of the security that was designed in. Luckily it took all of five minutes with the CIO to convince him and it then filtered down to the rest of the staff. However, the CIO had some trouble convincing his boss. To this day I have no idea why there was reluctance. It didn't cost any more to do it the proper way; other than the development and testing time of that section of code. When we presented the system to the board, as the replacement for the FAX method, not one person asked if it was a secure way of doing things. Go figure... /BACK patting On Wed Apr 25 12:37 , 'McKown, John' [EMAIL PROTECTED]sent: -Original Message- From: IBM Mainframe Discussion List [EMAIL PROTECTED]','','','')[EMAIL PROTECTED] On Behalf Of Rick Fochtman Sent: Wednesday, April 25, 2007 12:24 PM To: IBM-MAIN@BAMA.UA.EDU Subject: Re: Not mainframe but the latest in the TJMax fisaco - Because of their lax security measures, they now face several lawsuits.

And lack of choice is superior because choice leads to confusion. without necessarily subscribing to this view himself. It is, I think, important to understand that this is issue is not technical: It is political. In the appendix to his novel 1984 that describes the Newspeak language George Orwell wrote: The purpose of Newspeak was not only to provide a medium of expression for the world-view and mental habits proper to the devotees of Ingsoc, but to make all other modes of thought impossible. It was intended that when Newspeak had been adopted once and for all and Oldspeak forgotten, a heretical thought---that is a thought diverging from the principles of Ingsoc---should be literally unthinkable, at least so far as thought is dependent upon words. Its vocabulary was so constructed as to give exact and often very subtle expression to every meaning that a Party member could properly wish to express, while excluding all other meanings and also the possibility of arriving at them by indirect means. This was done partly by inventing new words but chiefly by eliminating undesirable words . . . Quite apart from the suppression of definitely heretical words, reduction of vocabulary was regarded as an end in itself, and no word that could be dispensed with was allowed to survive. Newspeak was designed not to extend but to diminish the range of thought, and this purpose was indirectly assisted by cutting the choice of words down to a mini-mum. Fanatic minimalists always have political agenda; they want to structure some microcosm so that in it things must be done their way and only their way.

NL Usage for Tapes
Someone asked the question about what good are reading tapes NL. There are valid reasons and these go back to the early years before diskettes, etc, when people wanted to tansfer data. Early, early on the universal mode of transfer was 7-track tape, BCD, Even-parity with no labels. People have heard about 2400 foot reels or even 3600 foot reels, but back then 300 600 foot mini- reels were prized. Along came 9-track 800 and even 1600 along with the capability to do ASCII formats with even ASCII labels. Other computer makers offered some capability of making IBM SL or AL labels. Some worked and some did not. So what I told everyone was no labels for I would only have to bypass them anyway most of the time. Interesting enough the IRS in the early years created a whole system of SUL (user Labels) which was really challenging. Besides the NL was preferred early on because most tape libraries ran with all SL tapes internally. When outside data came in the applications person coded NL and if OPS mounted accidently a SL tape to read, it would kick it down. This was preferred to having the code BLP. The use of BLP was tightly controlled for early security reasons. One offshoot of NL, SL, etc, was the writing of the many existing utilities to handle tape copying, dumping, and securing. One utility which came out was a program to read down all the data, jump over all the tapemarks to find the real end of data, and then write binary zeros out to the end of reel. A few times I got data tapes from corporations, jumped all the tapemarks and read meaningful sensitive corporate data beyond the logical end. The other directive was always to degauss the tape and relabel it for use. But then SYSPROG's sometime took shortcuts. I do not miss the old days at all.

Re: sysdsn enq
After all, batch processing FREEs all data sets between steps, but continues to hold the ENQ if a subsequent step uses the same data set name. I don't thinks that's accurate. DSN allocation is not cleared until EOJ. Hence the scramble with GDG's in a job, especially if you create more than one in the same one. The same thing can be proven with allocation for step N. Allocate a DSN under TSO and then submit a job. Even if a job will not touch the file for hours, the job will hang in ENQ. It's even 'worse' in a JES3 environment. The only way around it is dynamic allocations; then you have synchronisation issues. All OS's have enq-like structures, or they have data integrity issues.

Isn't software manufacturing based in Toronto these days? ** See what's free at http://www.aol.com. -- 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: sysdsn enq

Unfortunately due to a poor design in the ENQ support code it can be forced to hold the ENQ longer than should be needed. The situation I am talking about is when step 1 has an exclusive ENQ (DISP=OLD) while step 2 needs only a shared ENQ (DISP=SHR). Since the designers of ENQ didn't bother to support the capability to downgrade the ENQ from EXC to SHR (ie: Keep the ENQ but allocate it to any other task that was waiting for SHR access), step 2 maintains the EXC ENQ even though it only needs SHR access. For some reason, the ENQ code DOES allow a SHR to be altered to EXC if/when no other task has the QNAME/RNAME allocated (although I can not think of a situation where this is of any use). -- 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: Mainframe education program
Ryerson University in Toronto, Canada has announced a new certificate program focusing on z/OS technology that will start up in the fall. It was actually supposed to start in the spring, but there wasn't enough interest, so it got post-poned. - Too busy driving to stop for gas! -- 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: SVCDUMP vs. SYSMDUMP (was SP230?)
IBM Mainframe Discussion List IBM-MAIN@BAMA.UA.EDU wrote on 04/25/2007 11:37:30 AM: What does an SVCDUMP give you that an MDUMP doesn't? What did you think that an MDUMP is? The dump that ABEND takes for SYSMDUMP, like the dump that the DUMP and SLIP commands take, is an SVC dump. While SVC Dump and SYSMDUMP do share some common code, there are significant differences in processing, and we in development do not consider them to be the same. We use the term SVC Dump to refer to a dump initiated via the SDUMP(X) macro (including those initiated via the SLIP or DUMP commands). IEATDUMP and SYSMDUMP have much more in common - you could think of IEATDUMP as an API into SYSMDUMP processing. Jim Mulder z/OS System Test IBM Corp.
