Experiences in storing documents in Oracle DB?

Hi!

Does anyone have experiences in storing (standard-)documents (such as Winword-files, Excel-files, etc.) in an Oracle-database? I intend to write an application (using MSVC++ 5.0 and OO4O22) to manage (binary-)documents in a database with a minimum of filesystem interference. Currently I can think of 2

alternative solutions:

1. Treat the documents as OLE-container in the application and store it directly to e.g. a long-raw field in the DB. or
2. Create or edit temporary files on the filesystem, synchronize (i.e. binary copy) the files to e.g. a long-raw field in the database when finished editing and delete the temporary file afterwards.

Additionally the following requirements exist for the application that should also be considered:
* All docs should only be stored in the DB, not in the filesystem (obviously!)

• The user should NOT be able to save the document somewhere in the filesystem, instead of the db (saving a copy of the document to the filesystem

should nevertheless be possible!).
* Fulltext-search over the documents should be possible for quick
finding and access. (Maybe the Oracle Context-cardridge will help here???)

I have implemented test-programs of solution 1 so far, but the performance especially in creating large long-raw entries (above letīs say 2MB) in the database, is not that good. I would appreciate any suggestions or experiences,

also concerning efficient fulltext-search in binary database-fields.

Thanks,
