  • IFL = Integrated Facility for Linux. It's a dedicated partition on a mainframe... From Steve Adams, ODOT -- To answer your questions, we are using Linux on the IFL for production CVS source repositories and a small (but critical) piece of custom code that I wrote to accept socket communications from CICS in support of the Digital Photo License (DPL) application. The code for DPL also includes a monitor application that's quite useful for collecting stats for daily transactions and troubleshooting problems when they occur. The work-load is mainly I/O bound with the notable exception of the monitor application, it's running under Apache, with a static compile of mod_perl, and custom Perl modules that I wrote to interface with the proc file-system. We also make use of the SMB and NFS protocols for DASD access and LVM for file services.   We did a successful proof of concept connecting workstations to a 3270 emulator running in the IFL through ssh for client access to MVS. This work was significant since it secured an encrypted connection from the workstation to the emulator and all traffic from the emulator to MVS was local to the mainframe (nothing crossed the wire "in the clear"). We also found that the processor requirement of this concept was really quite light and most of the load was, again, I/O. In this effort we also tested connecting to Active Directory, RACF and running LDAP with a high degree of success. This work continues today but the scope is changing a little.   In the very near future we will be migrating off of Red Hat in favor of SuSE/Novell (we have purchased and received SLES8 under our existing Novell agreement). This is probably going to take a bit of time and energy and takes priority over testing and concept work. Once this effort is complete we will be looking at hosting some X application on a guest to see if we can expect reasonable performance for thin clients.

    1. 1. or Is Linux Ready for Oregon? Randy Kalmeta Program Director, Linux Technology Center, IBM Is Oregon Ready For Linux?
    2. 2. What Is Linux? <ul><li>An “open source” operating system </li></ul><ul><li>Fastest growing OS </li></ul><ul><li>Started in the early 1990’s by Linus Torvalds as a college project in Helsinki, Finland </li></ul><ul><li>Available to developers and users around the world via the Internet and/or from Linux distributors </li></ul><ul><li>Runs on many different computer architectures (Intel, Power, etc.) </li></ul><ul><li>Access and use allowed without encumbrances of software licensing fees under the GPL (GNU General Public License) </li></ul><ul><li>Allows collaboration on software development by programmers worldwide </li></ul><ul><li>Openness does not imply lack of control, there is a hierarchy of code maintainers leading up to Linus himself </li></ul><ul><li>Enables corporations like IBM to have a single operating system running across all systems offered to customers </li></ul><ul><li>Levels the playing field -- No one body controls Linux! </li></ul>
    3. 3. <ul><li>Community develops, debugs, maintains </li></ul><ul><li>Usually high quality, high performance software </li></ul><ul><li>Superior security - on par with UNIX, superior to Windows </li></ul><ul><li>More information: www.opensource.org </li></ul><ul><li>Examples of Open Source Software: </li></ul><ul><ul><li>Apache web server </li></ul></ul><ul><ul><li>Eclipse app development </li></ul></ul><ul><ul><li>Gnome desktop environment </li></ul></ul><ul><ul><li>Mozilla (Netscape) browser </li></ul></ul><ul><ul><li>Open Office (Star Office) productivity suite </li></ul></ul><ul><ul><li>Perl language </li></ul></ul><ul><ul><li>Samba file/print </li></ul></ul><ul><ul><li>SendMail mail server </li></ul></ul><ul><ul><li>Tomcat application server </li></ul></ul>What is Open Source?

    5. 5. The Open Source Development Model <ul><li>Linux is one of several open source projects </li></ul><ul><li>The Linux source code is available on several mirrored web sites </li></ul><ul><li>Contributors are allowed to make changes to code in order to fix or improve it under certain restrictions (primarily defined in the GPL) </li></ul><ul><li>Changes are typically posted to a mailing list or other public forum where they are reviewed and scrutinized by a group of peers </li></ul><ul><li>Based on the peer review, the changes will either be accepted or rejected by the Maintainer for that particular subsystem </li></ul><ul><li>If approved, the changes get integrated into the main source code base </li></ul><ul><li>This system has been described as a meritocracy, although it can be a brutal one! </li></ul><ul><li>Contributors span the gap from high school students to software professionals at major corporations </li></ul>
