Thank you. I have not run the command yet, and have been testing, but have not tested deleting items, collections, or communities, so I have not had the error you mentioned. I suppose that after I run this command I will need to run index-init again. I know it can't hurt, but is it necessary?
Thank you for this very clear explanation. -Jose -----Original Message----- From: Claudia Jürgen [mailto:claudia.juer...@ub.tu-dortmund.de] Sent: Thursday, April 22, 2010 2:19 AM To: dspace-tech@lists.sourceforge.net; Blanco, Jose Subject: Re: [Dspace-tech] running the 15 to 16 script Hello Jose, in that case you got to run: ALTER TABLE collection2item DROP CONSTRAINT "$2"; ALTER TABLE community2community DROP CONSTRAINT "$2"; ALTER TABLE community2collection DROP CONSTRAINT "$2"; The reason for this is: In Step 7 Update the database it can happen that not all the commands in the database_schema_15-16.sql are executed properly. The commands to drop foreign keys: ALTER TABLE collection2item DROP CONSTRAINT collection2item_item_id_fkey; ALTER TABLE community2community DROP CONSTRAINT community2community_child_comm_id_fkey; ALTER TABLE community2collection DROP CONSTRAINT community2collection_collection_id_fkey; assume that the keys got default names, whereas depending on the database version and operating system on which your instance started, they can have no names and just be counted internally. If you got no names or other names the script will skip the commands, with the following notes: psql:database_schema_15-16.sql:105: ERROR: constraint "community2collection_collection_id_fkey" of relation "community2collection" does not exist ALTER TABLE psql:database_schema_15-16.sql:108: ERROR: constraint "community2community_child_comm_id_fkey" of relation "community2community" does not exist ALTER TABLE psql:database_schema_15-16.sql:111: ERROR: constraint "collection2item_item_id_fkey" of relation "collection2item" does not exist This will lead to errors running DSpace as now 2 contraints exist and one is unable to delete items, collections etc. If you run into that error you got to inspect your db and use the references for the foreign keys: psql [YourDBName] \d [TableName] will show you the foreign keys, e.g.: \d community2collection Table "public.community2collection" Column | Type | Modifiers ---------------+---------+----------- id | integer | not null community_id | integer | collection_id | integer | Indexes: "community2collection_pkey" PRIMARY KEY, btree (id) "community2collection_collection_id_idx" btree (collection_id) "community2collection_community_id_idx" btree (community_id) Foreign-key constraints: "$1" FOREIGN KEY (community_id) REFERENCES community(community_id) "$2" FOREIGN KEY (collection_id) REFERENCES collection(collection_id) so the command would be: ALTER TABLE community2collection DROP CONSTRAINT "$2"; A Note will be added to the upgrade step in the DSpace documentation.
