FILE_DATASTORE??

Question

3.3.2.1.4 Specifying File Data Storage
The following example creates a data storage preference using the FILE_DATASTORE. This tells the system that the files to be indexed are stored in the operating system. The example uses CTX_DDL.SET_ATTRIBUTE to set the PATH attribute of to the directory /docs.
begin
ctx_ddl.create_preference('mypref', 'FILE_DATASTORE');
ctx_ddl.set_attribute('mypref', 'PATH', '/docs');
end;
Where is the location of '/docs' ?
If i want to search the file.html file, it is located in "E:\testdata\file.html" .
How can i set the 'path' attribute?
thanks!!

Answer 1

"/docs" is in the docs sub-directory of your root directory. The directory must be on the server, not on the client machine, Oracle must have read and write privileges to it, and the path notation depends upon your operating system. The demonstration below uses Oracle 10g on Windows XP.
SCOTT@10gXE> begin
  2    ctx_ddl.create_preference ('mypref', 'FILE_DATASTORE');
  3    ctx_ddl.set_attribute ('mypref', 'PATH', 'D:\testdata');
  4  end;
  5  /
