Q4:
If the Oracle documentation for Jena API states the max length is 22
characters (see original message for documentation info), then why
does Composer prevent model names longer 18 characters (can be seen
from File->New->RDF/OWL Oracle Database Connection)?
Hi Catrina
my previous response to your message was incorrect.
I read the following thread (while drilling down on Oracle export issues):
http://forums.oracle.com/forums/thread.jspa?threadID=1075381&tstart=0
This suggests a limit of 19.
I have experimented along the lines suggested in the thread, and can get
failures with model names of length 20 that do not occur with length 19.
So I am adjusting the length downwards from the previously advised figure.
Moreover, looking at this thread:
http://forums.oracle.com/forums/thread.jspa?threadID=1060129
there is a further issue with longer names particularly if your Oracle
user name is long! I have added workaround code for this issue, but they
may be some performance impact until Oracle fix it, and that fix gets
included in TBL. The workaround code will give a warning message if it
ever gets used.
All of this refers to the 3.3.3 release, currently in beta to customers
who have reported issues with Oracle RDF integration.
