Atmire responded about the issue with duplicate data in our Solr statistics
They noticed that some records in the statistics-2015 core haven&rsquo;t been migrated with the AtomicStatisticsUpdateCLI tool yet and assumed that I haven&rsquo;t migrated any of the records yet
That&rsquo;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):

<ul>
<li>Udana emailed me yesterday to ask why the CGSpace usage statistics were showing &ldquo;No Data&rdquo;
<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&hellip;</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 &quot;http://localhost:8081/solr/statistics-2010/update?softCommit=true&quot; -H &quot;Content-Type: text/xml&quot; --data-binary &quot;&lt;delete&gt;&lt;query&gt;*:*&lt;/query&gt;&lt;/delete&gt;&quot;
</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>
<h2 id="2020-12-06">2020-12-06</h2>
<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&hellip; indexing time for the DSpace Statistics API is the same&hellip; and I don&rsquo;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>
</ul>
</li>
</ul>
<p><img src="/cgspace-notes/2020/12/solr-statistics-2010-failed.png" alt="Error message in Solr admin UI about the statistics-2010 core failing to load"></p>
<ul>
<li>First the 2010 core:</li>
</ul>
<pre><code class="language-console" data-lang="console">$ chrt -b 0 ./run.sh -s http://localhost:8081/solr/statistics-2010 -a export -o statistics-2010.json -k uid

$ curl -s &quot;http://localhost:8081/solr/statistics-2010/update?softCommit=true&quot; -H &quot;Content-Type: text/xml&quot; --data-binary &quot;&lt;delete&gt;&lt;query&gt;*:*&lt;/query&gt;&lt;/delete&gt;&quot;
</code></pre><ul>
<li>Judging by the DSpace logs all these cores had a problem starting up in the last month:</li>
</ul>
<pre><code class="language-console" data-lang="console"># grep -rsI &quot;Unable to create core&quot; [dspace]/log/dspace.log.2020-* | grep -o -E &quot;statistics-[0-9]+&quot; | sort | uniq -c
24 statistics-2010
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>

<ul>
<li>Built and deployed it on DSpace Test but I am not sure how to run it yet</li>

<li>I sent some feedback to Atmire
<ul>
<li>They responded with an updated CUA (6.x-4.1.10-ilri-RC7) that has a fix for the duplicates processor <em>and</em> a possible fix for the database locking issues (a bug in CUASolrLoggerServiceImpl that causes an infinite loop and a Tomcat timeout)</li>
<li>I deployed the changes on DSpace Test and CGSpace, hopefully it will fix both issues!</li>
</ul>

<li>But I&rsquo;m not sure why the frontend doesn&rsquo;t show any data despite there being documents in the index&hellip;</li>
<li>I talked to Moayad and he reminded me that OpenRXV uses an alias to point to temp and final indexes, but the UI actually uses the <code>openrxv-items</code> index</li>
<li>I cloned the <code>openrxv-items-final</code> index to <code>openrxv-items</code> index and now I see items in the explorer UI</li>

<li>I installed <code>unoconv</code> in the backend api container and now it works&hellip; but I wonder why this changed&hellip;</li>
<li>Skype with Abenet and Peter to discuss AReS that will be shown to ILRI scientists this week
<ul>
<li>Peter noticed that <a href="https://hdl.handle.net/10568/110133">this item</a> from the <a href="https://cgspace.cgiar.org/handle/10568/24450">ILRI policy and research briefs</a> collection is missing in AReS, despite it being added one month ago in CGSpace and me harvesting on AReS last night
<ul>
<li>The item appears fine in the REST API when I check the items in that collection</li>
</ul>
</li>
<li>Peter also noticed that <a href="https://hdl.handle.net/10568/110447">this item</a> appears twice in AReS
<ul>
<li>The item is <em>not</em> duplicated on CGSpace or in the REST API</li>
</ul>
</li>
<li>We noticed that there are 136 items in the ILRI policy and research briefs collection according to AReS, yet on CGSpace there are only 132
<ul>
<li>This is confirmed in the REST API (using <a href="https://github.com/davesnx/query-json">query-json</a>):</li>
</ul>
</li>
</ul>
</li>
</ul>

$ query-json '.items | length' /tmp/policy1.json

</code></pre><ul>
<li>I realized that the issue of missing/duplicate items in AReS might be because of this <a href="https://jira.lyrasis.org/browse/DS-3849">REST API bug that causes /items to return items in non-deterministic order</a></li>
<li>I decided to cherry-pick the following two patches from DSpace 6.4 into our <code>6_x-prod</code> (6.3) branch:
<ul>
<li>High CPU usage when calling the collection_id/items REST endpoint
<ul>
<li>Jira: <a href="https://jira.lyrasis.org/browse/DS-4342">https://jira.lyrasis.org/browse/DS-4342</a></li>
<li>c2e6719fa763e291b81b2d61da2f8c758fe38ff3</li>
</ul>
</li>
<li>REST API items resource returns items in non-deterministic order

<li>After deploying the REST API fixes I decided to harvest from AReS again to see if the missing and duplicate items get fixed
<ul>
<li>I made a backup of the current <code>openrxv-items-temp</code> index just in case:</li>
