Well this a very special one I guess.
If I try to install Oracle 19.8 it runs fine, just 32 bit libs missing - which is known oracle bug.
But when I try to install a database the process crashes. Using the gui or the scripts...
The strange thing: No errors in the altertlogs. Just an end of comunication channel, when the database should be mounted.
"startup mount pfile="/u01/app/oracle/admin/DEBUG/scripts/initDEBUGTempOMF.ora";"
Attached the altert log. the create scripts and the tracefile of dbca.
Yes, I'll open an SR at oracle, but perhers someone here got an idea.
