File Upload Limit

The file upload widget is used to upload files from the end user's machine to your IBM i. By default, the file upload widget allows a maximum of 100MB of file data to be uploaded during a single transaction. This limitation exists to eliminate the possibility of tying up large amounts of server resources due to users transferring excessive data.

If the 100MB limitation is insufficient, it can be increased by defining environment variable PUI_UPLOAD_CAP in the Apache server configuration. The size is given in megabytes; any size can be used.

For example, to increase the limitation to 200MB per transaction:

Open the http.conf file for editing using edtf '/www/profoundui/conf/httpd.conf' from the command line.

Change this line:


to this:


As with any change to httpd.conf, a restart of the Profound UI webserver will be required.
