I want to upgrade DSpace Test to DSpace 5.8 so I took a backup of its current database just in case:
$ pg_dump -b -v -o --format=custom -U dspace -f dspace-2018-07-01.backup dspace
During the mvn package stage on the 5.8 branch I kept getting issues with java running out of memory:
There is insufficient memory for the Java Runtime Environment to continue.

<ul>
<li>I want to upgrade DSpace Test to DSpace 5.8 so I took a backup of its current database just in case:</li>
</ul>
<pre><code>$ pg_dump -b -v -o --format=custom -U dspace -f dspace-2018-07-01.backup dspace
</code></pre>
<ul>
<li>During the <code>mvn package</code> stage on the 5.8 branch I kept getting issues with java running out of memory:</li>
</ul>
<pre><code>There is insufficient memory for the Java Runtime Environment to continue.
</code></pre>
<p></p>
<ul>
<li>As the machine only has 8GB of RAM, I reduced the Tomcat memory heap from 5120m to 4096m so I could try to allocate more to the build process:</li>
</ul>
<pre><code>$ export JAVA_OPTS=&quot;-Dfile.encoding=UTF-8 -Xmx1024m&quot;
$ mvn -U -Dmirage2.on=true -Dmirage2.deps.included=false -Denv=dspacetest.cgiar.org -P \!dspace-lni,\!dspace-rdf,\!dspace-sword,\!dspace-swordv2 clean package
</code></pre>
<ul>
<li>Then I stopped the Tomcat 7 service, ran the ant update, and manually ran the old and ignored SQL migrations:</li>
</ul>
<pre><code>$ sudo su - postgres
$ psql dspace
...
dspace=# begin;
BEGIN
dspace=# \i Atmire-DSpace-5.8-Schema-Migration.sql
DELETE 0
UPDATE 1
DELETE 1
dspace=# commit
dspace=# \q
$ exit
$ dspace database migrate ignored
</code></pre>
<ul>
<li>After that I started Tomcat 7 and DSpace seems to be working, now I need to tell our colleagues to try stuff and report issues they have</li>

<li>Discuss AgriKnowledge including our Handle identifier on their harvested items from CGSpace</li>
<li>They seem to be only interested in Gates-funded outputs, for example: <a href="https://www.agriknowledge.org/files/tm70mv21t">https://www.agriknowledge.org/files/tm70mv21t</a></li>

<ul>
<li>Finally finish with the CIFOR Archive records (a total of 2448):
<ul>
<li>I mapped the 50 items that were duplicates from elsewhere in CGSpace into <a href="https://cgspace.cgiar.org/handle/10568/16702">CIFOR Archive</a></li>
<li>I did one last check of the remaining 2398 items and found eight who have a <code>cg.identifier.doi</code> that links to some URL other than a DOI so I moved those to <code>cg.identifier.url</code> and <code>cg.identifier.googleurl</code> as appropriate</li>
<li>Also, thirteen items had a DOI in their citation, but did not have a <code>cg.identifier.doi</code> field, so I added those</li>
<li>Then I imported those 2398 items in two batches (to deal with memory issues):</li>
</ul></li>
</ul>
<pre><code>$ export JAVA_OPTS=&quot;-Dfile.encoding=UTF-8 -Xmx1024m&quot;
$ dspace metadata-import -e aorth@mjanja.ch -f /tmp/2018-06-27-New-CIFOR-Archive.csv
$ dspace metadata-import -e aorth@mjanja.ch -f /tmp/2018-06-27-New-CIFOR-Archive2.csv
</code></pre>
<ul>
<li>I noticed there are many items that use HTTP instead of HTTPS for their Google Books URL, and some missing HTTP entirely:</li>
</ul>
<pre><code>dspace=# select count(*) from metadatavalue where resource_type_id=2 and metadata_field_id=222 and text_value like 'http://books.google.%';

count

</code></pre>
<ul>
<li>I think I should fix that as well as some other garbage values like &ldquo;test&rdquo; and &ldquo;dspace.ilri.org&rdquo; etc:</li>
</ul>
<pre><code>dspace=# begin;
dspace=# update metadatavalue set text_value = regexp_replace(text_value, 'http://books.google', 'https://books.google') where resource_type_id=2 and metadata_field_id=222 and text_value like 'http://books.google.%';

<li>I verified that the autowire error indeed only occurs on Tomcat 8.5, but the application works fine on Tomcat 7</li>
<li>I have raised this in the <a href="https://tracker.atmire.com/tickets-cgiar-ilri/view-ticket?id=560">DSpace 5.8 compatibility ticket on Atmire&rsquo;s tracker</a></li>
<li>Abenet wants me to add &ldquo;United Kingdom government&rdquo; to the sponsors on CGSpace so I created a ticket to track it (<a href="https://github.com/ilri/DSpace/issues/381">#381</a>)</li>
<li>Also, Udana wants me to add &ldquo;Enhancing Sustainability Across Agricultural Systems&rdquo; to the WLE Phase II research themes so I created a ticket to track that (<a href="https://github.com/ilri/DSpace/issues/382">#382</a></li>

<li>I was tempted to do the Linode instance upgrade on CGSpace (linode18), but after looking closely at the system backups I noticed that Solr isn&rsquo;t being backed up to S3</li>
<li>I apparently noticed this—and fixed it!—in <a href="/cgspace-notes/2016-07/">2016-07</a>, but it doesn&rsquo;t look like the backup has been updated since then!</li>
<li>It looks like I added Solr to the <code>backup_to_s3.sh</code> script, but that script is not even being used (<code>s3cmd</code> is run directly from root&rsquo;s crontab)</li>
<li>For now I have just initiated a manual S3 backup of the Solr data:</li>
</ul>
<pre><code># s3cmd sync --delete-removed /home/backup/solr/ s3://cgspace.cgiar.org/solr/

<ul>
<li>But I need to add this to cron!</li>
<li>I wonder if I should convert some of the cron jobs to systemd services / timers&hellip;</li>
<li>I sent a note to all our users on Yammer to ask them about possible maintenance on Sunday, July 14th</li>

<li><code>35.227.26.162</code> doesn&rsquo;t declare a user agent and is on Google Cloud, so I should probably mark them as a bot in nginx</li>

<li>Skype meeting with Peter and Addis CGSpace team
<ul>

<li>Peter told Sisay to test this controlled vocabulary</li>
<li>Discuss meeting in Nairobi in October</li>

<li>We have never seen <code>208.110.72.10</code> before&hellip; so that&rsquo;s interesting!</li>
<li>The user agent for these requests is: Pcore-HTTP/v0.44.0</li>
<li>A brief Google search doesn&rsquo;t turn up any information about what this bot is, but lots of users complaining about it</li>
<li>This bot does make a lot of requests all through the day, although it seems to re-use its Tomcat session:</li>

<li>So this bot is just like Baiduspider, and I need to add it to the nginx rate limiting</li>
<li>I&rsquo;ll also add it to Tomcat&rsquo;s Crawler Session Manager Valve to force the re-use of a common Tomcat sesssion for all crawlers just in case</li>
