Re: Simple iinventory control products?
Greetings All, We had CICS for 12-15 years, and along with it several MacKinney products - Hot Print, Morning News and KwikKey. We don't have CICS anymore, and our MacKinney products are gone now too. The products worked well, and we did not have any support problems with MacKinney.

Re: Question on Job Scheduling
W dniu 2012-02-10 21:28, Dan Gillis pisze: I have a meeting with a customer next week to talk about z/OS batch job scheduling. They claim to have about 20 scheduling employees. In my past experience, that seems about 4x too high. So I thought I'd ask the group the following question: How many job schedulers do you have, and how many MIPS is the environment? It doesn't depend on number of MIPS. It depends on: - number of jobs - number of environments (application instances, z/OS images) - environment complexity - change activity (new releases) - BUT NOT MIPS. Real life examples: a) modern company. Number of MIPS grew up approx 40 times, number of environments grew up 25%. Approx 400 000 jobs monthly, quite complex dependencies. Two folks on the beginning, now ...also two folks. b) old company. No job scheduler! Few hundreds MIPS, environment functionally stabilized (very few, very small changes in the application). Schedule table consist of few pages, it's printed by administrator, jobs are submitted by operators. The operators are mostly responsible for many other things (printing, ftp transmissions, backups), so real FTE cost is ZERO. c) huge government organisation. They started with homegrown, poor tools for scheduling and 20 person staff responsible only for batch. Now they have commercial job scheduler ...and the staff grew up. -- Radoslaw Skorupka Lodz, Poland -- Tre tej wiadomoci moe zawiera informacje prawnie chronione Banku przeznaczone wycznie do uytku subowego adresata.

BPX.EXECMVSAPF.program_name FACILITY class profile
In the recurrent tedious discussions here of relaxing the 100-character PARM length limit, the objection has been raised that this could subject authorized programs to the hazard of buffer overruns and the proverbial early termination, execution of arbitrary code, or escalation of privileges. However, lately in: http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/bpxzb1c0/2.30 Title: z/OS V1R13.0 UNIX System Services Programming: Assembler Callable Services Reference Document Number: SA22-7803-14 I stumbled upon: 2.30 execmvs (BPX1EXM, BPX4EXM) -- Run an MVS program | ... The argument can be from 0 to 4096 | bytes long except for unauthorized callers calling authorized | programs. For unauthorized callers calling authorized programs, the | argument can be from 0 to 100 bytes long. If you want to allow an | unauthorized caller to pass an argument greater than 100 bytes to a | program, a BPX.EXECMVSAPF.program_name FACILITY class profile | needs to be defined for that program. (Note revision bars. Plus a few Google hits; IBMLink tells me nothing.) So in a closely related context, IBM has recognized the hazard and provided a solution. I assume batch initiators could employ a siimilar technique, perhaps even the same FACILITY class, so buffer overrun need no longer be considered an obstacle to longer PARMs. -- gil -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN

Re: IBM Doing Some Restructuring?
Well, hindsight being 20-20, it is obvious management within IBM has done both some incredibly smart, and incredibly dumb moves over the past 30 yrs. or so. I know every time I applied for a job, I always wanted to work on a part time basis, because I just didn't want that feeling of security everyone has to some degree when they take permanent full-time employment. And every time I have worked on a part time job, when an offer came along for a full time position, I always turned it down. Mostly because I felt loyalty to the current employer for offering me the part-time, temporary position instead of making me take full-time employment. And for sure, we all know software development is much easier when you don't have the previous developers around to just clutter things up when you are spending all that time going thru the code to try to figure out why this or that function is coded the way it is. The idea of hiring temporary workers, the 'liquid' people referred to in the article, seems to me to be at odds with long term, successful growth. IBM is adopting Walmart's business model on this one. --Dave On 2/11/2012 10:06 AM, Edward Jaffe wrote: http://socialbarrel.com/ibm-job-cuts-in-germany-8000-may-be-laid-off/31574/ Rumor has it that IBM is laying off up to 40% of its workforce in Germany.

It's hard for me to understand how any serious development projects can be done by temps. Software development is not a math problem. You can't just throw bodies at it to get things done more quickly. You need a smallish group of highly skilled people--the kind that usually have permanent gigs--and time for them to learn the infrastructure and architecture before they can be truly useful. Also, as with any complex subject, the learning curves can be fairly steep. OTOH, perhaps the projects they're envisioning don't involve actual development. Maybe they involve customization of OTS packages? -- Edward E Jaffe Phoenix Software International, Inc 831 Parkview Drive North El Segundo, CA 90245 310-338-0400 x318 edja...@phoenixsoftware.com http://www.phoenixsoftware.com/ -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN
