Re: Question: z/VM 5.2 with z/OS 1.8 SYSPLEX and various Linux Guests
The last I heard, you can't run z/OS on z/VM. Regular VM is OK. Your best bet is to run z/OS in an LPAR by itself, and run z/VM in another LPAR.

Re: Calculations, anyone?
At prevailing rates per kw, you can figure on $600 per year per 1000 watts. A blade server rack with 5 shelves approaches 2 watts ($12,000), and a z990 with a single books costs 36000 ($21,600). One z990 costs less that 2 blade racks, and you can probably run z/OS on it at the same time you're running your z/VM. You also need 10 * 208 volt 30 amp power cords for a single 5 shelf rack, and you only need 2 60 amp cords for the z990.

I doubt if any of the software products Tom mentioned could make use of 6 or even 8 of the available CPUs, let alone all 32. As part of your licensing negotiations, you configure the Linux instance with the number of CPUs it can use, which should be the basis of your licensing issues. If you want 2 CPUs, you buy 2 licenses. Sure, we're back on the honor system, but Vendors are capable of arriving at equitable solutions when properly approached.

Re: VIPA and hot standby
Consider also an external appliance to do the failover. We use a Cisco Content Switch that sits outside the zSeries equipment so it can still administer the site if we need to bring down z/VM or the hardware for maintenance. For example, site 1 gets all the traffic unless it fails, at which time site 2 starts getting the traffic. If site 2 goes away too, site 3 is its backup, and is an Intel box with a single web page saying "Sorry, we're offline for a few minutes". When site 1 comes back, it starts getting all the traffic again.

Neither book told the whole story, but taken together, I stumbled my way through. I had to enlist the aid of a DBA to do the DB2 part. Schemas were a big guess. I did the LDAPADD commands as specified, and kept building things, but always ran into pre-reqs that didn't exist. I suppose the z/OS 1.3 schema source might have been lacking since I noticed enhancements in later releases of z/OS. Nobody here has the time or need to exploit the DB2 side yet - like you, we authorize using the RACF side. I also see the need for a administrative tool once the data is loaded.

Many of us old timers remember pouring over our programs to try to get them to run efficiently on the 360 processors.

Re: WAS 5.1 ND on z/linux
When garbage collection touches all those pages with such frequency, I would imagine that z/VM would want to consider them not eligible for paging. Even when a WAS virtual server is inactive, the working set size never shrinks, as would be expected. I've suspected this CPU and memory behavior in our WAS 4 and WAS 5 instances, and we'll investigate it further. It would appear that a direct port of an Intel architectured application may not play well with others in a virtual world. Perhaps software architects who are about to port to Linux on zSeries should spend some time in Hursley, England to see how the CICS folks learned to share.

There has been a marketing change for SuSE. I found out that you have to call your Novell rep, who can recommend a software reseller in your area that handles Novell products.

I use the Linux desktop client, but one is available for Windoze, too.

I use a SuSE desktop, too. Here's the instructions I put together to
remind me (I'm getting old) how to activate the new settings:
Keyboard remapping:
Apply these changes to make x3270 behave like Extra! Sessions:
Use a File Manager with root priveleges to access the
/home/userid
directory. Change the view to show hidden files and use Kedit or some
other editor to add theses statements to the end of .Xresources:
!
! Some adjustments to the keyboard of x3270:
!
x3270.keymap.custom:\
Escape:Reset()\n\
Return:Newline()\n\
Control_R: Enter()\n\
End: EraseEOF()\n\
Pause: Clear()\n\
Prior: PA("1")\n\
Next: PA("2")\n\
ShiftF1: PF(13)\n\
ShiftF2: PF(14)\n\
ShiftF3: PF(15)\n\
ShiftF4: PF(16)\n\
ShiftF5: PF(17)\n\
ShiftF6: PF(18)\n\
ShiftF7: PF(19)\n\
ShiftF8: PF(20)\n\
ShiftF9: PF(21)\n\
ShiftF10: PF(22)\n\
ShiftF11: PF(23)\n\
ShiftF12: PF(24)\n
!
! Now tell x3270 to use these adjustments.
!
x3270.keymap: custom
!
! then open a shell and issue: xrdb -merge .Xresources
When finished, save /home/userid/.Xresources and open a shell. Issue
the command xrdb -merge .Xresources to activate the overrides. The
next time you open a session with x3270, the changes will be in effect.
Different screen models:
Create an icon on the desktop and set the application path to:
'/usr/X11R6/bin/x3270' -model 3279-5 mvshost1
Change the model to 3279-4 or 3279-2 as needed, and change the host
field to vmhost1 as needed.

Re: Success stories, planning for success?
Most of the intelligent folks are probably cruising around Linux World today, so I'll take a crack at your question, Eric. First, and foremost, is the blessing of your management that they would truly like to see your implementation work. They should energize the other Administrators and Networking people so that everyone knows how management feels and how important their individual contributions will be to the success of the project. Pick the platform. If you have access to an IFL, you might as well lobby for z/VM. If not, find a decent xBox to work with. Pick your Linux distribution and get it on order. If working with the zBox, have someone take a class like IBM's ZV060 which teaches the installation of z/VM when intended for Linux. Decide which function you want to port to the new platform, like some static web pages that would work on Apache, or a file/print server. DB2 on AIX or Intel is also a good candidate. Don't make your first conversion too difficult. Assemble the team. IPL the coffee pot. Print the Red Books. Go to it.

SCO Christmas Letter
We received our Christmas letter from SCO, warning us that we may not make Santa's list next year if we persist in befriending penguins with questionable ancestry. Although dated on December 19th, the letter did not arrive in time for Christmas Eve and therefore could not be placed in the CIO's stocking. CIO immediately forwarded same to the barristers so that they might also enjoy the season's greetings. Has anyone else on this list received the SCO Christmas Carol?

Torvalds Slams SCO
http://www.eweek.com/article2/0,3959,1227150,00.asp eWEEK: For its part though, SCO has said that there are so many lines of code, and a variety of applications and devices that use that code, that simply removing the offending code would not be technically feasible or possible and would not solve the problem. Do you agree? Torvalds: They are smoking crack. Their slides said there are [more than] 800,000 lines of SMP code that are "infringing," and they are just off their rocker. The SMP code was written by a number of Linux people I know well (I did a lot of the SMP IRQ scalability myself, personally), so their claims are just ludicrous. And they claim they own JFS [journaled file system technology] too. Whee. They're not shy about claiming ownership of other people's code-while at the same time beating their breasts about how they have been wronged. So the SCO people seem to have a few problems keeping the truth straight, but if there is something they know all about, it's hypocrisy.

To a degree, IBM has listened to us. Look at the product mix that has appeared recently, generally at lesser cost: File Manager, Fault Analyzer, CICS/PM, RMF/PM (for Linux, too), DB2 Utilities Suite, etc. If you get weary of the constant contract negotiations, you can usually find something from IBM that will work, perhaps not as full functioned, but works.

Steve; I have the z/OS LDAP server running, with both TDBM (DB2) and SDBM (RACF) databases gen'd.

Re: DB2
Line us. We use UDB EE in Linux - works just fine and response time is quite good. DB2 Connect in a gateway instance can retrieve info from DB2 on z/OS. The performance is so close between the 2 that you can decide where to build your tables based on which side of your zBox has the capacity to spare. If you're watching your WLC budget, UDB EE might just be the ticket. As with all things Linux, "it depends". (And Linuxworld was great!)

Re: NTP, was: 2074 and the HMC
Another good solution is to have one of your routers (we use a Cisco 7507) configured as the NTP client of the cesium clock, and as the server to the rest of the network. All of our Linux instances go to the router to set their clocks. Considering the 4:00 PM stampede, I suppose some of the IS staff use it on their workstations, too.

Re: 2074 and the HMC
If I remember correctly, the z800 has no parallel channels. That
rules out native parallel 3274 or 3174 connection. However, the used
equipment market has 3174s with internal Escon, although pricey in
the $4,500 range. Parallel to escon converters are available, which
makes a regular 3174L parallel equipped usable for much less money
($<500). Used equipment dealers could set you up quickly. Try a
google search with 'used 3174 controller'. The 2074, if your budget
allows, is the best bet since a single unit can handle all the LPARs
you may define, with a console in each. We use an old 3274 parallel
attached controller to our z900.

A 3270 is required for the installation and configuration of z/VM.
Once the system is installed and configured (including VM TCP/IP),
then the system console on the HMC is sufficient to OPERATE the
system. Telnet can be used to access the system so that you can
perform additional system configuration. The requirement to have a
3270 for TCP/IP configuration is listed in the General Information
Manual ("TCP/IP for z/VM Hardware Requirements", p. 15 in z/VM 4.2
version).
The addition of an ifconfig command in z/VM 4.3 can reduce the need
for a 3270 even more, but permanent changes to your CP or TCP/IP
configuration will require a 3270 so that you can edit files (unless
you are big on line-mode editing or are a CMS Pipeline expert). If
you are using DirMaint, it is much easier with the menus, requiring
a 3270 (also mentioned in the General Information Manual).
On a personal note, I have never understood the aversion to having
3270 access for all LPARs on all CECs. Given the value you receive,
the IBM 2074, or similar non-IBM products, are worth the relatively
small expense. In an emergency, local 3270 access will be your best
friend. I would not want to try to wade through a TCP/IP console
log looking at traces using the HMC...

Re: Anyone running DB2 connect on linux - I just got asked where it keeps the log

Re: FYI Network printer problem - WAS - HOWTO define a network printer to Linux S/390
PSF on z/OS has had trouble connecting to some Lexmark printers without the port 9100 specification in the PRINTDEV specs. I recently had the same problem with an IBM Infoprint 1120, which was solved with the port statement as well. BTW, we use Infopriint Server on z/OS to spool from z/Linux (and desktop, too) into the JES queue where the high speed printers can do the work. On Thursday 19 December 2002 06:04, you wrote: Hi, Just for your information, we have 12000 (that´s it, twelve thousend) printers. They´re from Lexmark, IBM and Xerox. All of them have a problem with the LPD internal implementation. At some time the spool can not talk to the printer anymore because it does not receive the ACK for the SYN it sends (we can reproduce the problem using OS/2 and Linux). The solution, so far, is to print using the High Performance port (9100 at the Lexmark - I can´t remember the port for the other printers). To do that I recomend you use CUPS to do the job. Regards.

Re: LINUX & Security
Although I'm not deep enough into the process to be dangerous, you might want to look at the z/OS LDAP server. Check the Redbook "Securing Linux for zSeries with a Central z/OS (RACF) LDAP Server" and the two publications SC24-5923-03 and SC24-5924-02 dealing with administration and Client programming. It might answer some of your questions. We're looking at it as a way to perform the old RACHECK from a client application to authenticate a user's connection to a specific RACF group.
