http://localhost/ticket/1516 <p> CKAN 1.5.1 will introduce changes in the SOLR schema and functions to support multiple schema versions. Unfortunately the changes in the schema will be backwards incompatible so either both CKAN and SOLR are upgraded, or SOLR is configured as multicore, with one core for each schema. The solr cores would look like: </p> <p> <tt>http://&lt;solr-server&gt;/solr/schema-&lt;version&gt;</tt> </p> <p> Different scenarios: </p> <ul><li>Single SOLR instance used by only one CKAN site (e.g. SOLR running on the same machine): <ul><li>Update CKAN </li><li>Update SOLR schema (symlink to suitable version in CKAN source) </li><li>Rebuild search index </li></ul></li></ul><ul><li>Single SOLR instance used by multiple CKAN sites. <ul><li>Update CKAN source </li><li>Configure SOLR as multicore, one core for version 1.2 and another for 1.3 of the schema (symlink to appropriate version in CKAN source) </li><li>Update solr_url on each of the CKAN sites with the suitable core </li><li>Rebuild search index </li></ul></li></ul><p> These are the SOLR and CKAN instances that need to be updated (Please add any missing ones): </p> <ul><li>Same machine as the CKAN site: <ul><li>test.ckan.net </li><li>iati.test.ckan.net </li><li>data.gov.uk/ catalogue.data.gov.uk (confirm) </li></ul></li></ul><ul><li>s046.okserver.org <ul><li>iatiregistry.org </li></ul></li></ul><ul><li>s052.okserver.org <ul><li>datacatalogs.org </li></ul></li></ul><ul><li>s004.okserver.org / eu4.okfn.org / solr.okfn.org <ul><li>thedatahub.org (=www.ckan.net) </li><li>datagm.org.uk </li><li>publicdata.eu </li><li>hri.fi (dev.fvh.fi?) </li><li>it.ckan.net </li><li>ie.ckan.net </li><li>cz.ckan.net </li><li>register.data.overheid.nl (nl.ckan.net?) </li><li>no.ckan.net / datakilder.no </li><li>br.ckan.net </li><li>colorado.ckan.net </li><li>at.ckan.net </li></ul></li></ul><p> TODO: which SOLR server are using these instances? </p> <ul><li>data.norge.no </li><li>nederland.ckan.net </li><li>lt.ckan.net </li><li>pl.ckan.net </li><li>datadotmontreal.ca/ </li><li>ca.ckan.net / datadotgc.com </li></ul> en-us http://assets.okfn.org/p/ckan/img/ckan_logo_shortname.png http://localhost/ticket/1516 Trac 0.12.3 amercader Mon, 05 Dec 2011 18:09:23 GMT http://localhost/ticket/1516#comment:1 http://localhost/ticket/1516#comment:1 <ul> <li><strong>summary</strong> changed from <em>SOLR schema after 1.5.1 release and set up multicore SOLR instances if needed</em> to <em>Update SOLR schema after 1.5.1 release and set up multicore SOLR instances if needed</em> </li> </ul> Ticket johnglover Tue, 06 Dec 2011 09:32:46 GMT http://localhost/ticket/1516#comment:2 http://localhost/ticket/1516#comment:2 <ul> <li><strong>description</strong> modified (<a href="/ticket/1516?action=diff&amp;version=2">diff</a>) </li> </ul> Ticket amercader Tue, 06 Dec 2011 10:03:59 GMT http://localhost/ticket/1516#comment:3 http://localhost/ticket/1516#comment:3 <ul> <li><strong>milestone</strong> set to <em>current-ckan-sprint-2011-12-19</em> </li> </ul> Ticket amercader Tue, 06 Dec 2011 15:24:58 GMT http://localhost/ticket/1516#comment:4 http://localhost/ticket/1516#comment:4 <ul> <li><strong>description</strong> modified (<a href="/ticket/1516?action=diff&amp;version=4">diff</a>) </li> </ul> Ticket amercader Tue, 06 Dec 2011 15:25:30 GMT http://localhost/ticket/1516#comment:5 http://localhost/ticket/1516#comment:5 <ul> <li><strong>description</strong> modified (<a href="/ticket/1516?action=diff&amp;version=5">diff</a>) </li> </ul> Ticket amercader Wed, 07 Dec 2011 11:01:40 GMT http://localhost/ticket/1516#comment:6 http://localhost/ticket/1516#comment:6 <ul> <li><strong>description</strong> modified (<a href="/ticket/1516?action=diff&amp;version=6">diff</a>) </li> </ul> Ticket amercader Thu, 08 Dec 2011 16:00:20 GMT http://localhost/ticket/1516#comment:7 http://localhost/ticket/1516#comment:7 <ul> <li><strong>status</strong> changed from <em>new</em> to <em>closed</em> </li> <li><strong>resolution</strong> set to <em>fixed</em> </li> <li><strong>description</strong> modified (<a href="/ticket/1516?action=diff&amp;version=7">diff</a>) </li> </ul> <p> Closing as the main Solr servers are ready to support different Solr schemas.
