FILE_DATASTORE PATH

Hi guys,

I am pretty new to Oracle Text and have been confronted with a question that i can not seem to find the answer to - hope someone can help off the top of their head.

In the example :

begin
> *ctx_ddl.create_preference('COMMON_DIR','FILE_DATASTORE');
> *ctx_ddl.set_attribute('COMMON_DIR','PATH','/home/max/doc');
> end;

If I want to query what the path is for the datastore on another database - how would I query this? Where is this attribute stored...  

Hope this does not sound stupid.

Thanks in advance for any help.
