i've a 9i database and i want to concept a synchronisation between users and database who takes XML-files to send updated datas to the database.
The idea is that there is a web form which import and export XML-files.
And there are more then one user who do this.
First of all i want to know can Oracle handle this?
What happends if the first user sends his XML-file to the database->the procedure to parse the file runs and the next one want to send his XMLfile to the database?
Do you know an available concept?
The second question:
I've a complex XML-Schema and when i try to extract the XML-file i get this error message:
ORA-29400: Data Cartridge-Fehler
ORA-00600: Interner Fehlercode, Argumente: [invalid_mem_type], , , , ,
, , 
I read in an other forum it is neccesasary to upgrade to 184.108.40.206.0 or 220.127.116.11.0.
Is this right?
And which patchset should i take?
Thanks in advance.
With best regards
