RE: JVM in the database

Hi Jeff,

Have you ever processed files larger than 536870895 bytes?

Could you share the snippet which writes the BLOB into a file? Do you possibly stream it to an InputStream object, buffer it, and then stream it to the file with the FileOutputStream object?

If yes, what’s the buffer size? The code to allocate the buffer should look similar to this:

byte[] buffer = new byte[bufferSize];

Best regards,


I use a java procedure to dump blob files to an actual file. We store some PDF's in the database as blob and at times they need to be dumped to a files. Usually its when they want hundreds at time. We found doing this in a loop with PL/SQL was really slow and slower over time. I found a Java procedure to do this and is is super quick. We also have another to get file and directory information. It returned back more information that PL/SQL and also was really fast.
