Oracle UCM 11g - Uploading Large Files from ADF 11g Applications

By default, Oracle ADF 11g application allows to upload maximum 2 MB size files. Oracle WebCenter 11g Content Management ADF Task Flows inherit the same configuration from ADF settings. I will explain how to increase maximum file size and upload larger files into Oracle Content Server 11g.

For sample application I have increased maximum file size to 20 MB, you can download it from here - UCMNewFolderLarge.zip.

Let's test default file upload settings of 2 MB maximum and try to upload 15 MB file:

When trying to upload this file, as expected WebCenter Content Management task flow returns The file is too large error:

In order to set larger maximum file size setting, add following parameter into Context Initialization Parameters group of web.xml - UPLOAD_MAX_DISK_SPACE:

This example sets maximum file upload size to 20971520 bytes, or divided by 1024 and one more time by 1024 - 20 MB. Its common mistake, sometimes we keep forgetting to prefix this parameter with Trinidad library reference and not getting expected behavior - still File is Too Large error:

Make sure UPLOAD_MAX_DISK_SPACE parameter is referenced from Trinidad library:

After adjusting maximum file size to 20 MB, 15 MB file is uploaded to Oracle Content Server successfully:

Now I will try to upload 50 MB file:

WebCenter Content Management task flow returns The File is Too Large error and what a surprise - shows correct maximum size limit (20 MB):
