Hi, I am not able to delete items in my (upgraded) DSpace v4.1 system using JSPUI and SOLR Discovery/Browse/Search.
This was an upgrade via data migration from our existing PROD DSpace v1.6 system onto a new server running DSpace v4.1. The migration was carried out by “pg_dump”ing the data on v1.6 and restoring it to a new v4.1 instance, and then running the various upgrade scripts to upgrade the database from v1.6 to v4.1. Finally I re-indexed with “/usr/local/dspace/bin/dspace index-discovery –b” and updated the existing embargoes “/usr/local/dspace/bin/dspace migrate-embargo –a”. Everything appeared to be fine, but I have recently discovered that when attempting to delete an item I get the following postgres error: ERROR: update or delete on table "item" violates foreign key constraint "$2" on table "communities2item" My investigations have led me to believe that this table is related to the old Lucene indices – is this assumption correct? Anyone know if it is used by anything else? I have experimented with “cleaning out” the old lucene indexes using the following to rebuild the empty tables: /usr/local/dspace/bin/dspace index-lucene-init -r -t -v - this does throw one error: Elapsed time: 37 secs (37295 msecs) Exception: Caching is not supported by the ItemCountDAOSolr as it is not really needed, Solr is faster! org.dspace.browse.ItemCountException: Caching is not supported by the ItemCountDAOSolr as it is not really needed, Solr is faster! - but once I have run it, I am then able to delete items from DSpace without errors ☺ Has anyone else come across this (or similar)? Are my assumptions correct? And is rebuilding empty Lucene indexes a safe way to work around this? If not, has anyone get any other suggestions? I have, unfortunately, already gone live with v4.1 before picking up on this issue, so I am obviously very keen to find a fix asap and I’m hoping this is it? Any thoughts, observations, pointers or hints would be very welcome!
