Does OID repository needs Oracle TEXT?

Question

Does OID repository needs Oracle TEXT?
I remember in 10g I had to add this option, and don't remeber for what purpose. can't find any reference in 11.1.1.5 documentation what was it for?

Answer 1

If you are using a file datastore, then you load the file name into a varchar2 column and you do not load the whole file into a clob column. I have provided a demonstration below. In the demonstration below, the binarytree.txt file contains the word "test1" and the some_title.txt file contains the word "test2". The E drive contains a CD-RW disc, but the machine is my server. The drive and directory path that you use must be accessible to the server. You cannot use a drive on a client machine.
