Anybody know the new value for 2.6 kernel? For my kernel: EW 100-3FF SR 400-47F will do. YMMV, as I show below. The boundaries may be different for each kernel. You determine them as follows in the System.map: 1. page number of _stext (typically 0x1, so page 100 in hex) 2. last used page before _eshared (see note) 3. page number of _eshared (will be at start of segment, typically 400 hex) 4. last page before __bss_start The pages between #2 and #3 are not used. If you make the EW range for example 100-3FF it means that those extra pages are still saved in the NSS, but that's about all. If you have only a small number of pages there, it might make life much easier to use (#3-1) for it. When you set #4 too high, it will make the NSS bigger than necessary but the impact is not very much. If you set it too low, things will probably break because the kernel will find 0 where it expected initialized constants or code (I could have seen value in the kernel checking that during startup...) :p type=historical. I once did a patch to the ld script to make those entries stand out in the System.map, but that was rejected. That is the reason why my friend at IBM wanted to make the kernel issue the DEFSYS command, because the kernel knows those values best. Wearing my systems management hat, I do not want a Linux server to do things like DEFSYS. Activating a new kernel should be done under change control by the systems programmer. That's why we had a Linux server prepare a small Linux IPL disk and then used MAINT to create the new kernel with #CP IPL xxx PARM SAVESYS=SUSE8020 Funny enough this was obvious for the VM folks with gray/no hairs, but the Linux people in IBM felt this was a bizarre and utterly alien approach that no customer would want to learn... ;-) Obviously we maintained different levels of on different mini disks, and the contents could be saved and transferred to other sites (with IPDDR or whatever means you have to copy a non-CMS disk). The second part of the trick was that this small disk also contained an ext2 file system with the kernel modules. The Linux servers would link this disk R/O and the startup picked up the directory and tweaked it into /lib/modules That allows us to change kernels just by picking the right disk and segment, and rebooting.

How does Bacula interface with 3590 Tape drives, Does it Talk via a Escon channel to the A60 Yes. You need some help from CMS to manage any kind of changer or ATL (ie, DFSMS/VM, VMTAPE, VM Tape Manager, etc). You need the 3590 driver in the Bacula image that is running the SD, and you need the mount mods to mtx-changer in Bacula to get the other stuff working. Or Does it communicate with VM to Load tapes? The tools we wrote for Bacula communicate with a CMS agent to do mounts. The code in the Bacula package uses the native CMS tools (ATTACH, etc); you'll need to modify them slightly for the other TMS managers. Is there a better way of doing this? Better is a hard term. It's certainly idiotic that TSM for Linux doesn't do channel-attached tape, but that's why we did the Bacula work to make it aware of VM and the tape drives. Bacula does work well in this environment. It's the most mature (IMHO) of the open-source backup tools. It should work well for you.

Re: Create PDFs
Tom Duerbusch wrote: So, I was wonderingin the 21st century, there must be a better way. I'm thinking something that would take a base report, insert code into it and print it. Take all that crap out of the application program. I'm not tied to a PDF format. The bad part about PDF output is you need a print server to print the output. ...and Thomas Denier replied: The groff text formatter is free, and included in many Linux distributions. The formatter is built around a macro processor, and the exact input syntax depends on the choice of macro package. The macro package I am most familiar with uses a line starting with '.P' to indicate a paragraph break and a line starting with '.H' to indicate a heading. If your application program was re-written to produce groff input, the reports would still contain formatting information, but this information would be stated in terms of document structure rather than printer internals. This is a good suggestion, but I really don't think any ?roff-based language qualifies as 21st century. After all, roff pre-dates the Internet. :-) If you're going to rewrite the filter that converts your raw CICS output to a printable form, I'd suggest marking it up with XML tags. XML is going to be well-supported into the 21st century, and IMHO it gives you a lot more flexibility than roff. I've used both for many years, and much prefer XML. I'm going to get on my soapbox for a bit about this, and give you an earfull about document management. rant subject=Document Management level=abstract The key to having any flexibility with your documents is to separate the markup from the presentation, and the best way to do that is to use semantic markup. That's markup that expresses the meaning of the text, which is different from the structure or the representation. As an example, representational markup might use two line-breaks to indicate a paragraph, and structured markup would indicate the paragraph boundaries. But semantic markup would describe the purpose of some text: a step within a procedure or information about online devices, for example. The value of doing that is that by encoding information about the purpose of text, programs at various stages in the document preparation chain can make decisions on how to structure and represent them for you. Also, you've made a multi-purpose document that can be easily re-used, and targeted for different audiences or media. But why go to all that trouble? Well, it's not much trouble, you have to mark it up somehow if you want anything other than mono-font text, perhaps word-wrapped. You might as well do it in as general a way as possible, to give you the most flexibility so you don't have to come back and re-visit this again. /rant As a practical matter, though, which approach you take depends on your experience with markup languages. Roff is good if you know it, but as someone who's been using it for a few decades I wouldn't recommend it. It is too easy to slip back into writing representational markup, which then restricts what you can do with it. I'm suggesting XML because it is scalable: you can start by implementing some simple markup now, and other folks can add more semantics later on if they need it. But doing this does not require changing the entire document prep software chain, it usually only requires extensions to XML stylesheets. Of course, even if you do mark it up in roff, you can always run it through a roff - DocBook XML filter at some point if you need to. If you do use XML, you can convert your document into just about any format. The XML packages on Linux supply conversions to PDF, PostScript, HTML, RTF, and probably roff and others. BTW: your printer probably wants PostScript, and CUPS is set up to generate that from all sorts of input formats. I'd recommend rewriting your markup insertion program to put in some subset of DocBook XML to replace the PCL, then use something like OpenJADE to produce the PDF or PostScript from it. Better yet, produce HTML, put that on a web server and save some paper. :-) All this may be overkill for what you really need to do, but I'm not sure what your goals or limitations are here. It sounds like learning either roff or XML will involve a learning curve for you, so we should figure out which one is shorter.

The client recouped the cost of the box within 18 months mostly around license reductions. The horizontal growth with Oracle is great. With a license reduction from a lot to just 4, the initial project was self funded, almost. All new servers for other projects benefit from this. Same will hold true for WAS. Management is happy. Techs are happy. Apps are happy. Users are happy. So what's not to like? Why compare unreliable PC hard drives to reliable SANs, etc? If physical servers are so great why is this environment rife with challenges? No rack space? Power costs? Server creep? Unmanageable server farms? Staffing issues? Backups - don't make me laugh. Disaster recovery? - don't make my cry - we solved DR, what, in 1985? His argument about false metrics is just specious. Well, back to fantasy land. Oh, I suggest that if you have the opportunity present some of the success stories in our world. I'll be happy to discuss my success stories. But I will concede one major point: linux on z series is not for everybody.

The number of misstatements and outright errors in the first Murphy blog are too numerous for me to attempt to address in this note. He makes the all to common mistake of attempting to compare wildly different system architectures by comparing the processors' Mhz ratings...and this leads him to the erroneous conclusion that a Dell 1.4 Ghz 4 way PC will have the same throughput as a z9 system;-) However, for some *real-world* examples of consolidating Oracle onto Linux running under z/VM, please take a look at these presentations: 1) Total Cost of Ownership (TCO): Comparing System z and Distributed Platforms (http://www.linuxvm.org/present/SHARE109/S9265cfr.pdf) 2) Choose the Wrong Architecture and Waste Millions - A Customer Case Study (http://www.linuxvm.org/present/SHARE109/S9205mp.pdf) 3) How to Rise Above the Challenges of Deploying z/VM and Linux on the Mainframe and Thrive (http://www.linuxvm.org/present/SHARE108/S9230.pdf) ...pay particular attention to this one...

XML is going to be well-supported into the 21st century, and IMHO it gives you a lot more flexibility than roff. I've used both for many years, and much prefer XML. I'm going to get on my soapbox for a bit about this, and give you an earfull about document management. snip - MacK. - Edmund R. MacKenty Another plus to XML is that on z/OS, the XML processing can be offloaded from a general CP to a zIIP in the latest release of z/OS. This makes XML more fiscally attractive than it has been in the past. Also, under CICS, you could use write your code in Java (good built in XML stuff) and offload the Java processing to a zAAP. Again, more fiscally attractive than running it on a general CP. -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology The information contained in this e-mail message may be privileged and/or confidential.

Listen in to z/VM Security Architecture LVC - Oct 2
Hello VM and Linux enthusiasts on IBMVM, IBM-MAIN, and LINUX-390... The next in the series of Live Virtual Classes is planned for Tuesday, Oct 2. z/VM Security Architecture presented by Alan Altmark of IBM Date: Tuesday, October 2 Start Time: 11:00 a.m. Eastern U.S./5:00 p.m. CET Duration: 90 minutes Connect to the Live Virtual Class (LVC) session using via this URL: https://asp22.centra.com:443/GA/main/0174cb2101151026619cb338 You can connect to the LVC session up to 15 minutes prior to the start of the session. Abstract: Current z/VM customers are familiar with the isolation, security, and integrity features that z/VM provides. However, many customers running Linux on IBM System z servers for the first time are new to the world of Virtualization and seek reassurance not only that multiple Linux servers can share hardware resources efficiently, but also comply with organizational IT security policies. This presentation is an overview of the security and integrity characteristics of the z/VM operating system when used to host virtual Linux servers on IBM System z servers. Alan Altmark, IBM z/VM Development, will be the featured speaker for this 90-minute session. Open to Customers, IBM System z Technical Sales, System z Business Partners There is no charge to participate in this technical education session. Playback - This session will be recorded and a playback will be available following the live session via the URL referenced above. Look for further information in the Education section on the z/VM Homepage (http://www.vm.ibm.com) System Check The LVC will be delivered using the Centra tool that employs Voice over IP (VoIP) technology to provide both the audio as well as the visuals to your Windows workstation.
