First, I haven't moved them. I was just asking. The only "compelling" reason would be political. The Windows weenies here use ANY excuse to bad-mouth the zSeries. "Look! Even the mainframers keep their documentation on Windows! That says something about how much BETTER Windows is than the mainframe, doesn't it?!?" > > Was there ever a time when you needed to access the doc (on > windows) and > couldn't?

Our LAN storage administrator destroyed the entire share once. And the back had failed over the previous weekent (it takes them most of the weekend to do their backups). So we lost about 3 weeks worth of work. > > > The problem is that we only have 3390-3 sized volumes and don't want > any > > other size.

I don't understand this. I get whined at about using up volumes. That is how storage administration looks at things on the mainframe. Are you saying that using a 3390-3 is silly? That a 3390-<big momma> would be better? If so, then how do I get these large volumes at D.R.? The "industry standard" is 3390-3 and I've been told that getting any other size would cost a premium. We are migrating away from volume level to dataset level backups, so we will be able to address this later (if there is a later for the zSerie here). Also, we don't have PAV, so performance is an issue. PAV costs more money. We ain't getting it iffin it costs more!

Keep away from my PCs at home! At last count, on three desktops and one laptop, I probably have about 1.5 to 2 terabytes of disk. <none of it backed up - I finally got a DVD-R dual layer burner>. I wouldn't mind using less space on the Windows share, we certainly get whined at enough about it. But that is how much all the PDFs for vendor manuals, redbooks, et al, along with bloated MS Word documents take up. > > > Should something this large be zFS?

Another political plus is to be able to show management that the z/OS system can do web serving. Granted this is a minor application, but management is totally convinced that the z/OS system is "mired in the past" and cannot do things like serving web pages, SOAP, etc. That perception makes them immediately want to implement everything new on Windows. > > CC -- John McKown Senior Systems Programmer UICI Insurance Center Information Technology This message (including any attachments) contains confidential information intended for a specific individual and purpose, and its' content is protected by law.
