I'm working on a 9.14 HP-PPM Installation (not-clustered) and I have an issue with uploaded files.
We have our ATTACHMENT_DIR (in your case, /opt/ppm/attachments) which seems to be the folder where HP-PPM saves the attached files. But when we navigate to this folder, it is empty. I don't know if it's a problem concerning write permissions trough navigator, or there is a problem with the FTP server (don't know if it works with FTP).
ATTACHMENT_DIRNAME specifies the absolute pathname of the directory where attached documents are to be stored. This directory must give read/write access to Web browsers and, if the system includes an external Web server, exist outside the directory tree.
Also check the below parameter in server.conf.. Check the attachements in the directory specified at below link...
In 9.14, the folder to which attachments are saved is not necessarily the one defined in ATTACHMENT_DIRNAME.
If you want to know where your attachment files are saved, the easiest solution whenever using PPM 9.13 or later is to open Administration Console and click on the "DMS Configuration" menu.
Here, you will see where the files are actually saved.
Note that you should NOT directly modify the folder path from this screen without copying all the files to the new folder first, and this should be done while no user is using the system (otherwise you might miss some file very recently added).
In case it's not acceptable to prevent users from using the system, a safe way to change the folder is to use DMS "Migration" option. Just migrate to "File System" option again, but with the new folder value. PPM will copy automatically all the attachments to the new folder without any impact for PPM users, and without missing any file even if they are added to PPM during the migration process.
