Ok, SLES10 is not certified yet, Not even planned yet on metalink. But it will definitely be certified one day.
The first step is to install the necessary packages
1) db1 : Berkeley DB Database Library Version 1.85
this package is needed, in order to avoid :
httpd: error while loading shared libraries: libdb.so.2:
cannot open shared object file: No such file or directory
2) openmotif21-libs, sysstat
as listed in the quick installation guide for SLES9
3) libgnome and libgnome-devel
replace the old gnome-libs and gnome-libs-devel
ksh-93r seems to be suffisant
5) glibc 2.3 and gcc 3.3
no problem until yet by using glibc 2.4 and gcc 4.1
The second and last step is to launch the installer, with -ignoreSysPrereqs or with an updated install/oraparam.ini
That's all. I did get some warning about memory and requirements, but it seems that it works.
