2005-06-17 (17 Jun 2005)

The Linux on zSeries developerWorks pages are currently being tested at the new URL.


So you can start using the links we have been talking about since March 2005:
  • Online links: http://www.ibm.com/developerworks/linux/linux390/
  • In print use: ibm.com/developerworks/linux/linux390/
Some time on Monday 2005-06-20, re-directs from our old URLs will start to be effective:
  • http://awlinux1.alphaworks.ibm.com/developerworks/linux390
  • http://www10.software.ibm.com/developerworks/opensource/linux390
  • http://oss.software.ibm.com/developerworks/oss/linux390
It may be a while until the re-directs are effective, completely, but it is time to start changing your bookmarks and links on web-pages to Linux on zSeries developerWorks, as the re-directs will not be in place for ever.
Here is a summary of the changes effective on our new URL:
  • Previously, our web-pages were "*.shtml", now they are "*.html".
  • For the web-pages, directory-structure and [file-]names of the web-pages remain as before (except for the URL-handle, of course).
  • All patches, packages, OCO-modules will remain on the awlinux1-server for a while - but will be moved to an ftp-server in the next few months.
  • The PDFs with the manuals for our streams and documentation-downloads from the "Tuning hints & tips" are available on an ftp-server.
Here is some guidance for linking to our pages:
  • Please do not link to downloads (patches, OCO-modules, PDFs, etc.) from our pages, directly, but refer to the html-page where the link is shown.
  • Specifically, please do not link to PDFs, but to the "Documentation" page of the stream.
    As we found a lot of references to (old versions of) PDFs, we have established "documentation archives" for the active "April 2004" and "June 2003" streams (referenced on the "Documentation" page), with links to superseded (but still available) editions of the PDFs.

       Linux on zSeries pages temporarily hosted on awlinux1...

Since early March 2005, the Linux on zSeries developerWorks pages are available under a new URL:
http://awlinux1.alphaworks.ibm.com/developerworks/linux390/
As previously announced, hosting on awlinux1 is only temporary: The pages will be moved to a new URL later this year.
Unfortunately, our old URLs are not re-routed to their equivalent on the temporary home, but are re-directed to this page.
To ease the transition period, we have provided the navigation-bar below - so you can scroll and click.

We strongly recommend not to change any bookmarks, webpages, or documentation to the awlinux1-handle, now, unless you want to do it again in a few months.
If you are referring to our pages, refer to the homepage. When referring to sub-pages use text, e.g. kernel 2.6 based "April 2004 stream" (Recommended) and the date.
If you are reluctant to use the old URLs for our homepage:
http://www10.software.ibm.com/developerworks/opensource/linux390
http://oss.software.ibm.com/developerworks/oss/linux390
you may want to use the links we plan to migrate to:
Online links       http://www.ibm.com/developerworks/linux/linux390/
In print use       ibm.com/developerworks/linux/linux390/

Some time on Monday, March 7, 2005, the Linux on zSeries developerWorks pages will be available under a new URL. Structure and contents of the pages remain unchanged, only the URL-handle is different. Links to our URL-handles:
"http://www10.software.ibm.com/developerworks/opensource/linux390"
"http://oss.software.ibm.com/developerworks/oss/linux390"
will be re-routed to the new URL.
Please note: The Monday, March 7, URL is only temporary; it will be our handle for a few months, when we will have another home-URL.
Please do not change any links to Linux on zSeries developerWorks, next week, if you are not willing to do it again in a few months.
Specifically, please do not change any links on your web-pages, documentation etc., if they have a lifetime longer than a few months.
If you do change bookmarks and references (in your documentation, web pages, etc.), next week, please be prepared to change them again in a few months.
We will see to it, that the above URLs will be re-routed to the new home-URL, when that is ready. Sorry for the inconvenience.
