How to increase the maximum upload size

[veereshprasad sawadi]

As prescribed in Dspace7 documentation (under submission user interface/configuring the file upload step/basic settings), have tried increasing maximum upload file size by adding upload.max = -1 in dpsace.cfg but was unsuccessfull. Kindly help.

Hi,

The "upload.max" setting is no longer valid in DSpace 7.  It was removed during the 6.x -> 7.x upgrade, as it only applied to DSpace 6.x and below.

Because DSpace 7 uses Spring Boot for the backend, you can use Spring Boot's own settings to tweak the maximum size of an uploaded file.  See

https://spring.io/guides/gs/uploading-files/#_tuning_file_upload_limits

By default, DSpace 7 sets both "spring.servlet.multipart.max-file-size" and  "spring.servlet.multipart.max-request-size" to 512MB in this file: https://github.com/DSpace/DSpace/blob/main/dspace-server-webapp/src/main/resources/application.properties#L127-L134

However, you can override those defaults by specifying a *new value* in your "local.cfg" (as any settings in local.cfg will override defaults in that application.properties file).

So, you could, for example set: "spring.servlet.multipart.max-file-size = 1GB" to add a 1GB limit.  I believe you can also set these to "-1" to make the file upload unlimited (however there is always a risk that a very large upload will still fail if your request simply times out in Tomcat.)

Hopefully that helps. Let us know if there are other questions on this list.

Hi everyone, I want to ask a question. I'm just using DSpace v6.3 xmlui and I'd like to make some customizations to a function. so i have some questions i hope you guys can help me.

1. Is it possible to set the uploaded PDF to not be able to do "text selection, copy/paste"?

2. Is it possible to provide a simple PDF viewer, for example with an iframe?

3. Is it possible to provide an input field for password confirmation as re-authentication when a user accesses the collection?

Should I make changes to the release version folder like "dspace-6.3-src-release" or to the "Dspace" folder that appears after the "mvn package" command?

I hope all of you help, thank you
