Hello, Unfortunately, we'd need more information about the exact error you are seeing (preferably from the logs) to be able to help. Likely though, either your OAI index may have gotten corrupted in some way, or there's a specific Item (or a few items) that has not been indexed properly. You could consider trying a full OAI reindex (which can take some time on a large site) by running `./dspace oai import -c`.
I'd also recommend looking closer at your DSpace logs and pass along (to this mailing list) the exact error stack. It looks like you are getting a "NullPointerException" somewhere, but the location that is throwing that error might be the most important piece of information. More info on finding errors in the logs can be found here: https://wiki.duraspace.org/display/DSPACE/Troubleshoot+an+error Good luck, Tim On Thu, Mar 14, 2019 at 12:31 PM Zikrul <zikr...@gmail.com> wrote: > Hi, > > https://core.ac.uk/ is trying to harvest our repository (DSpace v5.6 , > JSP, Postgres, RedHat) but unable to do so as it is harvesting is failing > as different random points. > For example: > > Working: > > https://bura.brunel.ac.uk/oai/request?verb=ListRecords&resumptionToken=oai_dc////700 > > https://bura.brunel.ac.uk/oai/request?verb=ListRecords&resumptionToken=oai_dc////1000 > ..... > > Not Working: > > https://bura.brunel.ac.uk/oai/request?verb=ListRecords&resumptionToken=oai_dc////800 > > https://bura.brunel.ac.uk/oai/request?verb=ListRecords&resumptionToken=oai_dc////900 > ..... > > > The issue is similar to the url but still could not resolve. > > http://dspace.2283337.n4.nabble.com/Dspace-5-5-OAI-Error-when-request-td4683977.html > > > > Also found a solution at below url but didn't work for me. > > https://www.mail-archive.com/dspace-tech@lists.sourceforge.net/msg09661.html > > I am wondering if there is any idea which would be helpful to resolve the > issue please. > > > Kind Regards > Zikrul > > -- > All messages to this mailing list should adhere to the DuraSpace Code of > Conduct: https://duraspace.org/about/policies/code-of-conduct/ > --- > You received this message because you are subscribed to the Google Groups > "DSpace Technical Support" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to dspace-tech+unsubscr...@googlegroups.com. > To post to this group, send email to dspace-tech@googlegroups.com. > Visit this group at https://groups.google.com/group/dspace-tech. > For more options, visit https://groups.google.com/d/optout. > -- Tim Donohue Technical Lead for DSpace & DSpaceDirect DuraSpace.org | DSpace.org | DSpaceDirect.org -- All messages to this mailing list should adhere to the DuraSpace Code of Conduct: https://duraspace.org/about/policies/code-of-conduct/ --- You received this message because you are subscribed to the Google Groups "DSpace Technical Support" group.
