[Koha] What is the point of the Undo Import into catalogue feature?

Tue Dec 6 02:13:55 NZDT 2016

Hi,

Have you waited long enough for zebra to re-index your catalogue ? To 
me, what you are describing is not faulty. Once you reverted an imported 
batch, it takes time to zebra to remove the records from the indexes. 
Especially if you work with large files.

If you waited long enough and the indexes never got updated, I would say 
it's faulty, yes. But it you reverted the import and search for records 
right away, I would say it's just zebra that hasn't been able to reindex 
everything...

I was asked to remove the records for the titles we had not purchased. I expected it to be a simple task- press Undo Import, and pull all the records out, and add the 85 records purchased back in (I had been supplied with a file of our purchases).

When I clicked on the MARC 710 I was taken to a list of c.7,200 records via (in effect) the authority record for Kanopy (Firm). I could also navigate to that list on OPAC.

> However these tendrils were “faulty”. Clicking on the title (for example) in OPAC, took the user to a server error 404- Page not found. (But if they clicked on the 856 they were taken to the Kanopy platform).  In staff-side, clicking on the record resulted in an error “Record not found” (well, something similar). Attempting to export the MARC file by biblionumber resulted in an empty export file. (I have supplied my screenshots and notes directly to Fred King, who was asking what rubbish was left after my Undo).

I am tempted to have one more try, before raising this issue in Bugzilla. I suspect the Undo will not work, and that yet again we will have to have a re-index. And that in future we will have to rely on Batch Record Deletion, rather than the delightful Undo feature.

I have been using the Undo import (sort-of “unstage”) as I found this functionality astoundingly useful. It automated a task, reducing a tedious job to a couple of keystrokes.

(And what’s the point of that?) We had to have our database re-indexed to resolve the problem. Is there any point in the Undo feature if the indexer can’t cope? I hate to think what other dross I had left behind in earlier “Undos”!
