This page covers installation on IBM mainframes using OS/390 or z/OS, using Unix System Services - if you have Linux running on VM, see TWikiOnLinux instead.

Believe it or not, TWiki works just fine running on an IBM 9672 R66 CMOS machine under OS/390 Unix System Services. The biggest problem was getting the file upload function to work (actually turned out to be modifications to CGI
.pm) I like the fact that it can run under OS/390 and that it's self contained, nothing else required. I still have some tuning issues to be worked out but I consider the performance quite acceptable.

Interesting to hear about this - I used to be a sysadmin for Unix on a mainframe (actually Amdahl's UTS), but have never used IBM's Unix APIs (Unix System Services) for OS/390 or VM Open Edition. Of course, you could just run Linux but that's a bit more work

also has TWiki working on OS/390, using TWikiRelease01Feb2003
enabled on IBM HTTP Server V5R3
(5.3). See RewritingUrlsWithEscapedCharsUnderOs390
for the details - there's a small code fix required due to some URL encoding problems. The current patch is tested with IE, OperaBrowser
and Lynx, but MozillaBrowser
will probably have issues when used with I18N
in this environment. In fact, Oliver had this working already using the Sept 2001 release - a case of BeAwareOfQuietAdopters
Users of Linux on IBM mainframes can just use TWikiOnLinux
, which is ASCII based like other Linuxes.

If anybody would like to install TWikiRelease01Feb2003
on an IBM Mainframe, here is a little how-to-install:
I assume that Unix System Services
and the IBM HTTPD server
are installed and running.
You need to download the following Open Source Packages from the IBM FTP-Server
and install them according the documentation that can be found at Tools and toys page for z/OS Unix System Services
Unzip the TWiki distribution in a directory of your choice e.g.
Convert the text sources from ISO-8859-1 to IBM-1047 using
to reflect your installation.
of your webserver.
In our intranet, I use an SAF-Logon to map RACF-USERID to WikiNames
so i have a
entry for TWiki in
Apply both patches listed on RewritingUrlsWithEscapedCharsUnderOs390
and the Edit URL patch) - something like
patch -i ebcdic.patch
should work (you'll need to convert the patch files to IBM-1047 using

To any TWikiOnMainframe
users - there's a new TWikiBetaRelease
that should let users of Mozilla-based browsers work with mainframe TWiki sites that use I18N
), and avoids the user having to reconfigure the browser (for IE and Opera). Also, it would be helpful to have some mainframe people test this release since I don't have access to mainframes.

According to the change log on CPAN:CGI
version 3.02 at http://stein.cshl.org/WWW/software/CGI/
, attachment uploads should now work on EBCDIC mainframes.
