Re: Bad news for mainframes
I agree, why not zLinux. My shop is currently looking a the possibility of replacing several Oracle servers with on IFL running zLinux. It'll be a great savings in software costs by replacing several Oracle licenses with one. Of course the GPO IS government. So maybe this is another case of your tax dollars at work inefficiently.

The password is only suppressed if a X'0E' read is pending when the password is typed. The user might take a long time to type in the password and console output might get printed in the meantime. To get the output on the screen the 3215 driver would have to stop the outstanding read but that is not possible! The halt subchannel on an emulated 3215 devices does not have the desired effect. The read just continues. This means you can block the console by typing in a user name on the login prompt and then doing nothing. If the console output buffer is filled up by some messages this will stop the whole virtual machine. Only after the pending read has completed the system can continue. That is where I stopped with the patch for the 3215 driver, to me it is not acceptable that the system can drop dead because of a pending read. -- blue skies, Martin.

Bad news for mainframes
http://serverspecs.blogs.techtarget.com/2007/10/03/us-gpo-ditching-mainframes/?track=NL-576&ad=607019&asrc=EM_NLT_2315094&uid=5701628 U.S. GPO ditching mainframes October 3rd, 2007 by Mark Fontecchio The U.S. Government Printing Office is replacing some mainframe-based back-office software with two Oracle E-Business Suite applications running on a different platform. The GPO, which prints federal government documents for public consumption, already has Oracle applications running but it’s unclear on what platform. This press release from Guident Technologies, which is doing the outsourced work for the GPO for almost $1.6 million, doesn’t say. The GPO will be replacing the mainframe software with Oracle Project Costing and Project Billing, two components of its E-Business Suite. The E-Business Suite runs on Unix, x86 Linux and Windows platforms. From a short story in Washington Technology: The goal is to modernize and streamline the office’s two main business processes – Commercial Printing and Plant Printing. The implementation will enable the GPO to process orders from fulfillment through billing. It will also improve the agency’s ability to track costs and revenue. The new system is designed to improve cash management, control inventory flows and increase procurement efficiencies. I’m really curious to see what platform the GPO is running its E-Business applications on. If it’s Linux, this could become another Oracle certification issue. According to Oracle’s certification matrix, E-Business applications are supported on x86 Linux but not zLinux. Why?

The challenge was to decide how to merge it with the options already in the kernel command line. Sir Carsten could not make up his mind, and following well established tradition, he decided to do the opposite of what we had implemented :-) I don't think he picked up our "autocase" feature either (we folded an all-upper command line into lowercase). But you should be able to use it to force runlevel 1 during startup, for example. Anything beyond that will probably require CMS and a Diag8 to have a mixed case IPL command.

It is easy enough, was even coded as a customer contribution in the 2.4 days. Does not preclude LOADPARM action nor current parmfile operation nor even SCSI parm handling. Let the VM "PARM parm" (via gen registers) prepend a string to other parm functions. No big deal! But a great payoff for the majority of mainframe Linux customers. -- R; -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
