Welcome to IWETHEY!

New Please have the grey beards define UFAM for you.
I'll bet they can't do it without making you feel belittled for asking what it actually means.

Virtual storage access method (VSAM) (for disk storage) has included in its superset of Datasets (all being record-oriented filesystems); Relative Record Data Set (RRDS) (of which User File Access Method is inclusive of this), Key Sequenced Data Set (KSDS), Entry Sequenced Data Set (ESDS) and Linear Data Set (LDS).

Effectively, UFAM will win on mainframe, everyday and twice on Sunday. Mainly because other systems don't handle data this way. It is like using a Sun 32 Processor, 64GB Memory, 10000 to manage data with Pen and Ink on Parchment then crumpling it up and using a photocopy of the wrinkled up parchement for the record.

Sure it can do it... but why would you?

What about asking a Mainframe to provide an Oracle Database. Sure it could do it but it would be slower than the Sun Box doing the Pen and Ink thing.

Even the TLA (ok FLA) RRDS means Round Robin Data Set on nearly anything else.

I'd like to see a full definition from your Grey Beards on UFAM. If it doesn't mention access methods, then someone is blowing smoke up your butt. Also ask them if it is SO GREAT, how come you can't hook up any Network CRM/ERP/LaaaTeeDa to it over the network? Gotta Remember They are ALWAYS TALKING Local Access methods for this stuff. Local access only (ala batch systems) like that is relevant now a days.

New So? (Playing devil's advocate)
Maybe it's not as efficient trading that data back-and-forth with other systems, but if you do everything on the frame, is it faster than doing eveything without the frame? And yes, he's talking about the batch processing, specifically [link|http://www.google.com/search?q=DDA%2bsweep.|DDA+sweep.].

Purveyor of Doc Hope's [link|http://DocHope.com|fresh-baked dog biscuits and pet treats].
A properly built system will be a order of magnitude less costly than a 'frame setup for the same speed. Or an order of magnitude faster for the same cost.

Your choice. Frames are only around because people are scared to LEARN and grow. Frames are built to do two things and two things only... local data access, and servicing green screens (sometimes now behind screen scrapers).

Network data access for Frames is MIGHTY expensive, some I know of are $55K just for one port, additional $25K for up-to 3 more.

Direct Demand Sweep Account(1) processing is something already being done on *NIX systems already at a far smaller cost than aframe is. Including the custom written software and maintenance.

Hell you could devote an entire rack of 1U machines to do it even faster. While providing the networking infrastructure at a third the cost, including software and maintenance.

Batch processing is a protected setup, they know it. It is all hidden. Why do batch processing on a Frame when you can do event based or epic based transactions.

I'll be honest, there isn't an arguement you can make allowing you to be heard. The Mainframe is the DATA SAFE... IT CANNOT BE CHANGED... OLD == GOOD. Why buy a new safe when the old one isn't broken? (2)

Go ahead and play the Devil's Advocate. It won't make any difference in any case.

Peter let us not get started about VMS and capabilities based setups. It wasn't the question posed or told to Drew as to why they aren't on the extinction list.

Maybe you should bring up the case of PVC sanitary pipes, in the 50's plumber swore up and down that it was the devil's product. Black Iron piping was FAR BETTER and in the Long run was cheaper to maintain... therefore it would never catch on. BTW, when was the last time you've heard of Black Pipe being used for anything except Natural Gas or High Pressure Steam?

Sure, 'frames still have a place, but not one your Grey Beards think.

(1) = I have a "sweep" for putting all of my General Account money in an Interest Bearing Sweep Account for 5 minutes a day (11:57PM until 12:02AM) so it can bear interest at a really nice rate. As GA money cannot be interest bearing in the US. Right now it pays for the Monthly Fees... as I don't have a ton of money in it. But for some companies with $100K running balance in a GA, it makes a difference.

(2) = Yeah, whatever, Safes built in the 1920's are GREAT safes... but not "Human Safe", things like automated locks, ventilation and electro-sealing are rather new. But who needs this stuff Huh? Maybe the Dead Clerk accidentally asphixiated when the fire alarm went off and shut the safe door... might.

     So what's UFAM? - (drewk) - (18)
         you sure he said ufam? - (boxley) - (8)
             google UFAM mainframe - (drewk) - (7)
                 Appears to be a file format? - (ChrisR) - (6)
                     My (limited) understanding - (drewk) - (5)
                         Wasn't that supposed to be one of the magical things about - (Another Scott) - (4)
                             Maybe the 400 was bringing that from the frame world ... - (drewk)
                             Yup "DB2/400" IS the filesystem. -NT - (imric) - (2)
                                 As an interesting side note - (jake123) - (1)
                                     So, explain what "Oracle's Raw Disk Access" is? - (folkert)
         Clueless - (broomberg)
         Please have the grey beards define UFAM for you. - (folkert) - (2)
             So? (Playing devil's advocate) - (drewk) - (1)
                 HAHA. - (folkert)
         Any real definition of UFAM? - (folkert) - (1)
             I don't have a dog in that fight - (drewk)
         And my MF guru's response: - (broomberg) - (2)
             First link on Google seemed to be referencing it - (drewk) - (1)
                 And when you ask - (broomberg)

But clearly, it's unreasonable to use a sledge hammer to drive upholstery tacks.
