问题
I have an ASP.NET application (vb.net codebehind) that has serious performance problems because of its storage of TIFF files in one server share. There are over a million .TIF files there now! The application tracks the scanned images of property with a corresponding row in an Oracle database table. We have this idea that it might be better to store the images themselves in a new Oracle table. How can this be done?
The alternative solution we are thinking of is to split up the server share into multiple folders by State (an OH folder, a WV folder, a VA folder, etc.) Seems like the database option might make more sense long-term, but how do we do it? Can a TIFF be stored in a BLOB column and then extracted back into TIFF format using .NET? Anyone know how?
回答1:
Yes, you can store a TIFF file in Oracle's BLOB data type.
Check out this link to get BLOB field contents with ADO.NET.
回答2:
Besides from storing in a database, if you separate groups of one thousand files in different folders, performance should increase a lot. Folders with a very high number of files get a severe downgrade in performance when in a windows enviroment
