Hi Erick, thanks for the hint. Indeed, i just forgot to paste the <updateLog> </updateLog> section into the email. It was configured just the same way as you wrote. Do you have any idea what else could be the cause for the error?
Best regard, Gero -----Original Message----- From: Erick Erickson [mailto:erickerick...@gmail.com] Sent: Wednesday, November 23, 2016 5:00 PM To: solr-user <solr-user@lucene.apache.org> Subject: Re: Problem with Cross Data Center Replication Your _source_ (i.e. cdcr_testa) doesn't have the CDCR update log configured. This section isn't in solrconfig for cdcr_testa: <updateHandler class="solr.DirectUpdateHandler2"> <updateLog class="solr.CdcrUpdateLog"> <str name="dir">${solr.ulog.dir:}</str> <!--Any parameters from the original <updateLog> section --> </updateLog> </updateHandler> The update log is the transfer mechanism between the source and target clusters, so it needs to be configured in both. Best, Erick. P.S. kudos for including enough info to diagnose (assuming I'm right)!
