WebSphere Host On-Demand fully supports Japanese (menus, 3270 screens,
online help, documentation, etc.) You can load it on any HTTP server,
including a Mac OS X HTTP server. (Unofficially. Truthfully any HTTP server
will do, as long as it has a reasonable file system. Untar or unzip --
whichever you prefer.) It works with either Safari or Firefox on the Mac
client. I think it also supports Java Web Start on the Mac (running
outside the Web browser). I recommend the z/OS HTTP Server -- best place
to install Host On-Demand. Second best place is Linux on z.
It is probably possible to untar/unzip HOD to a local client drive and use
a "file:///" URL in the browser (or Java Web Start) to load it.
Unofficially. There is a documented procedure for doing something very like
that ("SETUP CLIENT") on certain client platforms. Ideally you'll have an
HTTP server so others can join in the fun (and pay IBM a modest fee for
each license, of course).
There's an administrator deployment tool called the Deployment Wizard
that's a Java program packaged as a Windows-only executable. (No, that
wasn't my idea.) If you install it on Windows and know what you're doing
you might be able to move it to a Linux or Mac desktop and run it there.
It's optional, though -- you may not need to run it depending on whether
you want to customize how HOD behaves. There is a documented, manual
(non-wizard) process for customizing HOD start pages if you can't stand the
Deployment Wizard and don't mind text editors.
Main product page here:
http://www.ibm.com/software/webservers/hostondemand
There's an older demonstration (two versions back) available from the link
on the left hand menu here:
http://websphere.dfw.ibm.com/whidemo/
That URL's final slash is important in certain browsers.
The "Try Your Own Host, Download Client" flavor is the one I'd recommend if
you want to just kick the tires and not see too many security prompts
asking you to entrust your browser to IBM. (You might see one, though.)
Then go look at "What's New?" in V9 and V10 to get a feature update. They
keep V8 out there just in case you're tempted to use IBM as your HOD
server. :-) It's in English (menus, online help), but you can flip the
3270 datastream to Japanese if you want to see how that works.
Disclaimer: I work for the company that produces this product. But it's
actually a very good product, even if I am biased.

Another free open source TN3270 client alternative from www.z390.org

Can anyone list some good free ones that there I > > can find? John, all The z390 Portable Mainframe Assembler open source project www.z390.org offers another alternative for supporting TN3270 client. if you download and install the latest z390 v1.3.00 for Windows or Linux, you will find it has a Graphical User Access Method (GUAM) option which includes basic TN3270 client supporting full screen TGET and TPUT macro svc interface. There are demos including DEMOGUI6 which illustrate support of multiple tabbed fields, numeric fields, color, PF keys, etc. The z390 GUAM TN3270 support written in J2SE Swing GUI Java could easily be combined with the new z390 Service Oriented Architecture (SOA) client server messaging support which uses J2SE Java TCP/IP sockets support. The result would be a functioning TN3270 client on a TCP/IP network. I will add a demo z390 TN3270 client driven by another z390 server running on the same TCP/IP network in the near future. All that is required to start testing this new z390 option is to pair up the existing TGET and TPUT interfaces to the GUAM TN3270 client interface with the existing TCPIO SEND and TCPIO RECEIVE interfaces. There is also an existing SOA client server demo using the TCP/IP support for messaging. It may well take a little work on the part of interested z390 project members, but the result will be a portable open ended TN3270 solution. On a related note, prolific z390 project developer Melvyn Maltz has a brand new proto-type CICS transaction processor up and running using z390 with some very interesting initial transaction rate statistics with z390 transaction manager using CMDPROC multi-tasking support to drive multiple transaction processing tasks. z390 is written entirely in J2SE Java and supports the assembly and execution of mainframe assembler on any platform supporting J2SE. z390 includes extensive demos and regression tests and has been fully tested on Windows XP/2000 and Ubuntu 6.06 LTS Linux. To learn more stop by the SHARE presentation in Tampa, Florida on Monday Februrary 12, 2007 at 3:00 PM, visit www.z390.org, and join the z390 user email group discussion.

About 50% of the responses have been for non-free products, so I don't believe his response is out of line. The first responder pegged it - if you want a really good emulator, you're gonna pay for it. The freebies are ok (x3270 in particular), but not as usable. Personally, I've used the IBM product that Tim mentions, and I've used the others, including x3270, QWS3270, and Vista, and I agree with his assessment on HOD (and it's fat-client brother) - "it's actually a very good product."

This seems to leave the file at least partially open, but closed enough that I could FREE the DDNAME. I'd almost expect a program check from an attempt to manipulate previously freed resources. I think I interpret the APAR text a little differently than you do, gil. To me it seems like the UNIX task termination code runs before the DCB-related task termination code, and so has already deleted the UNIX-related information that underlies the DCB, before the DCB-related code can flush the buffers and close the DCB. Thus the 614 abend that the APAR talks about. So, the system is closing the DCB during task termination, but we have the situation where two things need to happen in a particular order, and they're out of order right now.

Re: Need a FREE TN3270 client to connrect to Mainframe?
Hi Timothy, As a TN3270 junkie I actually purchased a previous version of the IBM Host Access Client Package myself for home use. I collect TN3270 clients the way some people collect... collectible things (stupid brain cells still offline). The Host Access Client Package is very pricey at $238 though I recall I paid even more about $300 so it has actually gotten less expensive. That IBM does not offer PCOM outside of this bundle at a more competitive price really makes it hard to consider for many folks. Vista http://www.tombrennansoftware.com/ is my current favorite and I use it at home and work. QWS3270 PLUS (non-free) http://www.jollygiant.com/ is also a strong recommendation based on excellent support from Jim Rymerson when I was on the vendor end of the data stream. I used to point folks to Jim's trial copy to prove that bugs were in the TN3270 emulator they were using and not the 3270 data stream. There are a number of other excellent emulators available for under $100. IBM PCOM has a heavy footprint and a high price tag but to be balanced it is a very good product and I consider it the gold standard for implementation of the protocols. We use HOD for most folks here but in a support role I prefer the speed and flexibility of having a TN3270 client on Windows. No need to fiddle around with a Java version conflict in the middle of the night after being paged. Linux or Mac OS X are not options on the corporate network for desktops.

Re: Doubt about Server Pac and Catalogs
Just for reference... here was your original post: >From my little knowledge, I prefer not cataloging more datasets than >necessary in the master. I don't know if this is a wrong positioning. Is it? Then that is a good practice. I don't put any data sets in the MCAT these days that aren't part of the OS. Since you can use VOLSER for LNKLST and LPALSTxx, no requirement to. We still do have a few leftovers here from days of old with a special ISV HLQ that was used just for LNKLST / LPALSTxx data sets to put them in the master catalog. Some of the groups who install software (other than "MVS") still do this but I try to get them to rename the data sets to follow the same standards as their other data sets. The only downside is needing to change volsers in PROGxx or LPALSTxx if the data sets are moved to another volume. Not a problem for the "MVS" group since our ISV products go on a volume that is part of the sysres set and are cataloged with symbolics.

SIO in SDSF vs read/write speed
I made the following observation: 1. WRITE. I put some data to tape (3592J). The average transfer speed was approx. 70MB/s. SDSF shows very high SIO rate for the job, approx. 2500. Data generated by IEBDG, blocksize=32720, RECFM=FB, LRECL=80 2. READ. I read *the same* data, which I previously wrote. Got even higher transfer speeds, approx. 100MB/s,but significantly lower SIO rate, approx. 40 Dataset (FB 80 32720) read by ICEGENER. I think, ICEGENER reads the data in much larger chunks, so the number of I/O is lower, but the speeds is even greater.

Don't know if you are right that ICEGENER reads in larger chunks (block size and/or two or more block-reading CCWs chained together), but if true then that would account for the higher effective data transfer rate. Highest possible data transfer rate would be doing only one I/O request that has enough CCWs in it to read the whole tape. Anything less than this will result in lower than maximum possible data transfer rate. This is not practical in the general sense, as each read CCW needs page-fixed storage for the block it is reading, you don't know in advance how much data is on the tape, and the amount of storage needed to be page-fixed could easily be far more than all real storage on the system.

Cascading FICON director with DASD and TAPE devices
>As long as I can remember REWIND is done disconnected from the channel, but >the 3480 is the first drive I looked at for performance. As I recall the thing that tied up the channel was the forward space file (move tape to tape mark I think). Whether this was as true for the 3480 as it was for the reel to reel tapes I don't know. But the problem was that there was a NOP chained to the REWIND, FSF, hence the channel/device tie up. I thought that the NOP was removed ages ago (d/t 3480 era) though.

BRLM and GRS (from z/OS Hot Topics)
Thank you Birger for the link to the new z/OS Hot Topics newsletter. I have a question concerning the byte range lock manager article. After reading about the various evolutions of the BRLM (single environment, shared, recovery considerations within a sysplex), I was wondering why the locking mechanism was redeveloped! It seems to me that GRS is the perfect server (or manager - if we can call it that) to maintain any locks that the z/OS UNIX environment needs to serialize its resources.

Re: SIO in SDSF vs read/write speed
IEBDG uses BSAM or QSAM (probably BSAM, but I don't know for sure and it doesn't really matter) to write buffers. By default, the number of buffers is normally about 10, which means an average 5 buffers per I/O. ICEGENER will do larger chunks of I/O using EXCP, thus the lower SIO rate and higher transfer rate. If you use real IEBGENER you will probably see similar rates for both. Or, you can specify a BUFNO=99 on the DD statements for IEBDG and IEBGENER and probably see about the same rates as ICEGENER.

According to the zOS V1.7 ISPF Dialog Developers Guide, a VER option of LISTX (list excludes) implies that the NON-BLANK option is specified, thus requiring an entry.

LPAR Org & Security
The question I'll get to: How are your shops organized when it comes to LPAR organization, access and security? To explain where I'm coming from: 1) LPARS We have two. PROD supports everything from TSO users and program development to multiple instances of IMS and DB2 and batch processes. TEST2 is an exact image of PROD created with volume level snapshots and is used for testing upgrades and troubleshooting issues. 2) Networks We have two. Production, of course, has most things connected to it, including the PROD LPAR, and all the other production servers in the company. It also has a ton of development and QA servers connected to it, along with the TEST2 LPAR when we want it there. The other network is called NEQAL, and is our separate testing network. We dynamically build pieces of our production environment there when we want to test upgrades and changes before we do it on the production network. The TEST2 LPAR is sometimes connected to this network when the testing there needs to involved the mainframe. With that explained, we've recently had a security question come up. Should the TEST2 LPAR only be connected to the NEQAL network? You see, this would then force a user to use a workstation in a separate location, not at their desktop, in order to perform work on TEST2. In this way, then, the possibility of someone becoming confused about which LPAR they are looking at on their desktop is minimized. In other words, I, systems engineer, would be less likely, as an example, to stop TCPIP accidentally on the PROD LPAR because if I'm sitting at my desk, I know its the PROD LPAR, and if I'm in the NEQAL lab, I know its TEST2. Right now, I can swap from PROD to TEST2 at my workstation. We systems engineers are, of course, arguing that we need that access as a matter of productivity. It really opens a can of worms, since if they were to dictate that, we would soon be arguing that all the development and test servers should also only be on the NEQAL network. And then we get into the arguments about where the production instances of DB2 verses the 3 test instances should be running. Separate LPARS? Ug. So the main question I want to ask you all is this: How are your shops organized when it comes to LPAR organization, access and security? Most of us have only worked in our own shop, and so learning what others do will help us decided which course of action is best - and convince management of it! THANKS!

And then we get into the arguments about where the production instances of DB2 verses the 3 test instances should be running. Separate LPARS? Ug. What is the cost of fully splitting the two networks and workloads? Part of that cost will be the building of a limited interface for production control to promote test source to production (I assume that this is done now in your shop). This limited interface may be a set number of DASD volumes that only production control can write to (from the test side), but which the production system reads for application software load libraries and storage of the production copy of source. Or, the copying of load members (and such) to tape and then loading from tape (would this require a different bank of tape drives in a different room -- don't laugh a certain USGov't installation where I've worked did exactly this). Next will be the cost of maintaining the two systems. Since you can't log in to the other LPAR, you probably can't access the other LPAR's DASD (other than for the exception above). This means that you will have to either have two PCs on your desk, or you will have to have two offices. Or you will have to have some other means to access each system in such a way that you won't accidentally make some change that should have been to/with the other system. This will also necessitate dual security data bases... So how far should one go in doing the splitting? And is management willing to give up the ability to fix the other system when it crashes and can't be IPLed?

Make the default security label for your TSO systems engineers match the test system security label. In order to muck with the production system, you must log-on and explicitly specify the security label for the production system. Ensure all "privileged" or "authorized" commands and access procedures are protected by the appropriate security label. So, if you logged onto with the default security label, you won't have the authority to issue production system commands; only test system commands are available. If you try to log-on to a test system with a production system security label, RACF will reject the log-on. I am not a RACF expert. Two cents worth. Your mileage may vary. Jeffrey D.

Re: 3480 IDRC drives using 3490E media
With the exception of the extended-length 3490/E cartridges, they are the same media. A standard length 3480 cartridge can be used on a old non-IDRC 3480; 3480's with IDRC and 3490/E drives. It is physically the same cartridge.

Does anyone know if IBM supports writing to 3490E cartridges (re-initialized to 18 track) using 3480 IDRC drives? I have successfully run a few test cases, but I do not want to instruct the client to purchase 3490E media without first confirming it is a supported environment.

Re: Recalling A Message in Lotus Notes
I'm sorry to be so late with a reply, but I understand the need for this. Here's what I do. I run Lotus Notes with a local replica on my machine. In your location document click on the Mail tab, and look at the bottom where it says "Transfer outgoing mail if [ ] messages pending". I will set that to some number like 9. That means my mail does not automatically get sent immediately.It means it won't automatically get sent until the next scheduled replication, or until 9 messages are pending, whichever comes first. This allows me to survive that "Oops!" moment when I wish I could recall something by deleting the outgoing message and rewriting it before it ever gets sent anywhere.That also means that if I do want to send something immediately, I have to remember to click "Send and Receive Mail". It won't actually recall anything that has already been sent, but it does allow me to have a chance to fix things that I realize are wrong right AFTER I send them.

I don't necessarily disagree, but I was replying to the original poster's question about tools/utilities. It depends on how frequently time/date-related issues could affect your system and applications(*), the scope of testing, the relative risk/cost of time-related failure(s), labor costs, and the (full) cost of the tool. Really they're the same basic principles you'd apply in deciding whether to get any testing tool. As it happens I was working with some colleagues yesterday to figure out whether we should use a particular testing tool in a new project, and we debated all those factors. For the record, I've since learned CA has a competing product called AllFusion Date Simulator. Princeton Softech has another product in this category called HourGlass. There may be yet others. (*) Japan, for example, doesn't have DST. Businesses here with purely domestic operations may not have the same issues as businesses that operate in Australia, the U.S. (including especially Indiana), etc. I should also mention that it's not necessarily only your own code that merits testing. Middleware, operating systems, and tools/utilities can also be relevant. Ronald Reagan said "Trust, but verify" concerning Soviet treaty obligations, and maybe that's good advice for testing vendor software as well. :-) - - - - - Timothy Sipples IBM Consulting Enterprise Software Architect Specializing in Software Architectures Related to System z Based in Tokyo, Serving IBM Japan and IBM Asia-Pacific E-Mail: [EMAIL PROTECTED] -- 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

No, not giving it away yet, sadly. I haven't opened my personal basement data center yet. Almost. :-) IBM doesn't publish too many System z hardware prices, I'm afraid. IBM has revealed some data points, though. A shiny new System z9 BC Model A01 "starts at $100,000" (i.e. U.S. dollar price in U.S., education/government). IFLs, zAAPs, and zIIPs (the speciality engines) for the System z9 BC are US$95,000 each and US$125,000 each for the z9 EC (one-time charge), IBM says. Memory is US$8,000 per GB on the z9s. Ironically Boeing doesn't publish prices for new aircraft either. :-) But like IBM, sometimes you get clues. The used/secondary market is another way to get public price information. A few brief bits of potentially money-saving advice: 1. Yes, do calculate the costs of a new system (hardware), but please also include all the other costs. All IT systems have running costs of various kinds, and the hardware very, very strongly influences these other costs. New systems cost a lot less to run, quite simply, ceteris paribus. [The rough analogy here: imagine if your data center is filled with 1,000 or more distributed servers, but every bit of equipment is at least 8 years old. Economical? Probably not. A mainframe is effectively a whole data center in a tiny box.] 2. Boeing has other mainframes I'd guess. Could you get an LPAR or two on a Boeing System z9 elsewhere in your enterprise to run this workload? While a new mainframe may be cheaper on a running basis, adding work to an existing mainframe could be even cheaper than that. (It depends, but that's common.) 3. Do make sure you investigate VWLC (Variable Workload License Charge) for your software. This can often be quite advantageous. 4. A system upgrade is a good time to "take stock." Take the time to review your software portfolio and do make sure it's modern and responsive to your application development needs, in particular. Mainframe software stacks are only as old as you keep them, and they're as new as you want them. Mainframes can run old software indefinitely, but it doesn't mean they have to or should. Keep the old stuff if it still has business value. Sit down with an architect-type if you'd like help reviewing the stack. I can recommend a few. Also take a look at what's not running on the mainframe today and whether it should. Aside: I wish Boeing would quote me a price on a cargo shipment aboard the Dreamlifter. I've got a wide item to ship. - - - - - Timothy Sipples IBM Consulting Enterprise Software Architect Specializing in Software Architectures Related to System z Based in Tokyo, Serving IBM Japan and IBM Asia-Pacific E-Mail: [EMAIL PROTECTED] -- 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
