[Archivesspace_Users_Group] Archon migration SortOrder values

[Flanagan, Patrick]

Hi Phillip,

I've tried doing this through an SQL query; does the query look correct to you? I assume anything with the name Title and ParentID is a duplicate, but that might be wrong.
select Title, ParentID, COUNT(*) FROM tblCollections_Content GROUP BY Title, ParentID HAVING count(*) > 1 \G

That returned 7506 rows with various counts, so I hope I'm incorrect! Or would it be easier to look and see from the Archon interface itself?

Patrick,

     Check for duplicates in your classification hierarchy on the Archon side. It can cause the migration to fail.

Thanks,

Phil

Subject: [Archivesspace_Users_Group] Archon migration SortOrder values

Good morning,

A little while ago I messaged the group about a null pointer exception during migration from Archon -> ArchivesSpace. This question is semi-related to that.

Among the checks to perform before migration is one relating to duplicate SortOrder values in tblCollections_Content. The associated query to perform is: "SELECT ParentID, SortOrder, count(*) from tblCollections_Content Group by ParentID, SortOrder HAVING count(*) > 1;"

I didn't fix that in the current instance I'm migrating because count(*) adds up across 144 rows to be well over 10,000. I'm wondering if that might be the cause of a null pointer exception when attempting to migrate from Archon. A sample of the latest error I've received:

Getting records for: ?p=core/classifications&batch_start=1801
get: https://archon.klnpa.org/psa?p=core/classifications&batch_start=1801
Status code: 200
Status text: Created
response: No matching record(s) found for batch_start=1801
java.lang.NullPointerException

        at org.nyu.edu.dlts.dbCopyFrame$1.run(dbCopyFrame.java:231)
        at java.lang.Thread.run(Thread.java:745)

I was wondering: are the SortOrder values largely arbitrary? If I write up a quick script just to ensure each one has a unique value, would that potentially solve the issue? It's affecting numerous migration attempts. Thank you for your time,
