btw : this bug has been opened with bug-id 18391, but because does not fit 
in component "anotherlevel", it was not changed for five days and it is 
probably asigned to the wrong person at redhat I opened this bug.

quoting from bug 18391 :

gspear :
when create database use dbassist, process stop there do nothing.

srt :
this problem was discussed on oracle's technet, too.
http://technet.oracle.com:89/ubb/Forum7/HTML/004821.html
oracle thinks its a problem is an interaction with the new GNU Lib C 
shipped
with RH 7.
oracle sais they have communicated the problem to Red Hat.

any statement from redhat regarding this would be nice...
