Not sure on how you work on the first half of that, but there’s a helpful video on working with subject trees:

 

https://wiki.eprints.org/w/Training_Video:Subject_Trees

 

You’ll probably need to copy your subject tree from the old repository over, and then run import_subjects pointing at that file.

I’m back!

 

Progress has been made. So, I’ve tried this with clearing out the eprints table and starting the import from fresh – success! Of a kind…

 

It’s imported one record; this one – http://eprints.lincoln.ac.uk/25828. This is a complete record with related documents. Hurrah!

 

However there should be a total of four records imported. The import threw up some new and interesting errors:

 

Starting EPrints Repository.

Ending EPrints Repository.

 

Now, my interpretation of this is that it’s unable to get the documents that are not open access – which is fine, however how can I get it to grab any protected documents? Can I provide username and password alongside the import? Also, is this likely to be why the records are not being imported correctly or is there something else here I’m misinterpreting?

 

Finally, looking at the repository I can access the record directly through the URL, however I can’t see anything through the browse by… view. I’ve regenerated views/abstracts and started the indexer. The search gives this error:

 

The Lincoln Repository has encountered an error:

 

The top level subject (id=jacs) for field "subjects" does not exist. The site admin probably has not run import_subjects. See the documentation for more information.

 

As always, any thoughts are appreciated!

Hi all!

 

So, a week or so later and I’m back onto this. I’ve double verbosed it and exposed a bunch of extra debug stuff. One line in particular stands out for me on all 5 test records I’m trying to import:

 

Database execute debug: INSERT INTO `eprint` (`eprintid`) VALUES (?)

 

So… it looks like it’s not inserting anything into the database?

 

I’ve put the error log as well as the XML snapshot I’m trying to import up onto Google Drive here if anyone has time to take a look: https://drive.google.com/open?id=0B67FaE28LeB-Z3NZVGtRQkFsbVU

 

I am trying to get through this without shouting for help at every turn, I promise! ;P

 

Andrew

 

 

 

That’s interesting – I’ll have a check although this action is only being done on a subset of 4 or 5 records, all of which are fairly recent, so I would have hoped they’d have a status! The only other alternative could possibly be missing status definitions etc? I shall take a look at bringing phrases over as well.

 

 

'ne' means 'not equal' - when comparing strings ('!=' means not equal when comparing numbers).

 

At a guess, something in your export doesn't have an eprint_status set (all EPrints should have this set). You may be able to find these in the database by trying something like:

mysql>  SELECT COUNT(*), eprint_status from eprint GROUP BY eprint_status;

This should result in the eprint_status values of inbox, buffer, archive and deletion, with a count next to each. Any count for 'NULL' would show where the eprint_status is not set, and therefore where the uninititalized string is on the import.

 

Cheers,

John

 

 

Cheers Adam,

 

That seems to have sorted things out. However, I have another new and interesting error!

 

Use of uninitialized value in string ne at /usr/share/eprints3/bin/../perl_lib/EPrints/DataSet.pm line 1090.

 

The line in question is:

 

if( $dataobj->get_value( "eprint_status" ) ne $self->{id} )

 

and the ne in that line is an operator if I’m not mistaken? So is this an issue with Perl running on the server?

If you’ve added all your metadata fields to the new repositories configuration, you need to do:

 

<eprints_root>/bin/epadmin update <repositoryid>

 

This will update your database structure.

 

 

 

Hello all! Thanks for the pointers yesterday regarding import/export. I’m at a point where I now have exported data and am trying to import it. Initially I was getting errors relating to missing metadata fields which I’d thought I’d corrected, however I am now finding errors relating to missing SQL tables:

 

SQL ERROR (execute): SELECT `eprintid`,`pos`,`subjects_loc` FROM `eprint_subjects_loc` WHERE `eprintid` IN (25940)

SQL ERROR (execute): Table 'lirolem.eprint_subjects_loc' doesn't exist

DBD::mysql::st fetchrow_array failed: fetch() without execute() at /usr/share/eprints3/bin/../perl_lib/EPrints/Database.pm line 2674.

DBD::mysql::st execute failed: Table 'lirolem.eprint_creators_browse_id' doesn't exist at /usr/share/eprints3/bin/../perl_lib/EPrints/Database.pm line 3211.

SQL ERROR (execute): SELECT `eprintid`,`pos`,`creators_browse_id` FROM `eprint_creators_browse_id` WHERE `eprintid` IN (25940)

SQL ERROR (execute): Table 'lirolem.eprint_creators_browse_id' doesn't exist

DBD::mysql::st fetchrow_array failed: fetch() without execute() at /usr/share/eprints3/bin/../perl_lib/EPrints/Database.pm line 2674.

 

Now, my question is, do I need to do something to rebuild the tables relating to the metadata in some way prior to an import? Or is there something else I’m missing here? Maybe not all the field definitions?
