Atmire responded about the issue with duplicate data in our Solr statistics
|
|
|
|
They noticed that some records in the statistics-2015 core haven’t been migrated with the AtomicStatisticsUpdateCLI tool yet and assumed that I haven’t migrated any of the records yet
|
|
That’s strange, as I checked all ten cores and 2015 is the only one with some unmigrated documents, as according to the cua_version field
|
|
I started processing those (about 411,000 records):

<li>Udana emailed me yesterday to ask why the CGSpace usage statistics were showing “No Data”
|
|
<ul>
|
|
<li>I noticed a message in the Solr Admin UI that one of the statistics cores failed to load, but it is up and I can query it…</li>
|
|
<li>Nevertheless, I restarted Tomcat a few times to see if all cores would come up without an error message, but had no success (despite that all cores ARE up and I can query them, <em>sigh</em>)</li>
|
|
<li>I think I will move all the Solr yearly statistics back into the main statistics core</li>
|
|
</ul>
|
|
</li>
|
|
<li>Start testing export/import of yearly Solr statistics data into the main statistics core on DSpace Test, for example:</li>
|
|
</ul>
|
|
<pre><code>$ ./run.sh -s http://localhost:8081/solr/statistics-2010 -a export -o statistics-2010.json -k uid
|
|
$ ./run.sh -s http://localhost:8081/solr/statistics -a import -o statistics-2010.json -k uid
|
|
$ curl -s "http://localhost:8081/solr/statistics-2010/update?softCommit=true" -H "Content-Type: text/xml" --data-binary "<delete><query>*:*</query></delete>"
|
|
</code></pre><ul>
|
|
<li>I deployed Tomcat 7.0.107 on DSpace Test (CGSpace is still Tomcat 7.0.104)</li>
|
|
<li>I finished migrating all the statistics from the yearly shards back to the main core</li>
|
|
</ul>
|
|
<h2 id="2020-12-05">2020-12-05</h2>
|
|
<ul>
|
|
<li>I deleted all the yearly statistics shards and restarted Tomcat on DSpace Test (linode26)</li>

|

<ul>
|
|
<li>Looking into the statistics on DSpace Test after I migrated them back to the main core
|
|
<ul>
|
|
<li>All stats are working as expected… indexing time for the DSpace Statistics API is the same… and I don’t even see a difference in the JVM or memory stats in Munin other than a minor jump last week when I was processing them</li>
|
|
</ul>
|
|
</li>
|
|
<li>I will migrate them on CGSpace too I think
|
|
<ul>
|
|
<li>First I will start with the statistics-2010 and statistics-2015 cores because they were the ones that were failing to load recently (despite actually being available in Solr WTF)</li>

|
24 statistics-2015
|
|
18 statistics-2016
|
|
6 statistics-2018
|
|
</code></pre><ul>
|
|
<li>The message is always this:</li>
|
|
</ul>
|
|
<pre><code>org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException: Error CREATEing SolrCore 'statistics-2016': Unable to create core [statistics-2016] Caused by: Lock obtain timed out: NativeFSLock@/[dspace]/solr/statistics-2016/data/index/write.lock

</code></pre><ul>
|
|
<li>I will migrate all these cores and see if it makes a difference, then probably end up migrating all of them
|
|
<ul>
|
|
<li>I removed the statistics-2010, statistics-2015, statistics-2016, and statistics-2018 cores and restarted Tomcat and <em>all the statistics cores came up OK and the CUA statistics are OK</em>!</li>
