I am trying to get a working connection between my workflow and viewer servers. Before I dig into the NFS-configuration, I wanted to test that indexing in the viewer worked. So I have created and finished a process on my workflow server, and then manually copied the .xml file into the hotfolder on the viewer server. The indexer runs for a couple of seconds and moves the file from the hotfolder to the error_mets, where it says in the .log file: ‘PI not found’. Does anybody know what PI refers to? Is it a project ID from workflow or something? Does it happen because I am testing it in a funky way?
