<li>Looking at log file use on CGSpace and notice that we need to work on our cron setup a bit</li>
<li>We are backing up all logs in the log folder, including useless stuff like solr, cocoon, handle-plugin, etc</li>
<li>After running DSpace for over five years I’ve never needed to look in any other log file than dspace.log, leave alone one from last year!</li>
<li>This will save us a few gigs of backup space we’re paying for on S3</li>
<li>Also, I noticed the <code>checker</code> log has some errors we should pay attention to:</li>

<li>So this would be the <code>tomcat7</code> Unix user, who seems to have a default limit of 1024 files in its shell</li>
<li>For what it’s worth, we have been setting the actual Tomcat 7 process’ limit to 16384 for a few years (in <code>/etc/default/tomcat7</code>)</li>
<li>Looks like cron will read limits from <code>/etc/security/limits.*</code> so we can do something for the tomcat7 user there</li>
<li>Submit pull request for Tomcat 7 limits in Ansible dspace role (<ahref="https://github.com/ilri/rmg-ansible-public/pull/30">#30</a>)</li>
<li>Try to do some metadata field migrations using the Atmire batch UI (<code>dc.Species</code> → <code>cg.species</code>) but it took several hours and even missed a few records</li>
<li>A better way to move metadata on this scale is via SQL, for example <code>dc.type.output</code> → <code>dc.type</code> (their IDs in the metadatafieldregistry are 66 and 109, respectively):</li>
</ul>
<pre><code>dspacetest=# update metadatavalue set metadata_field_id=109 where metadata_field_id=66;
UPDATE 40852
</code></pre>
<ul>
<li>After that an <code>index-discovery -bf</code> is required</li>
<li>Write shell script to do the migration of fields: <ahref="https://gist.github.com/alanorth/72a70aca856d76f24c127a6e67b3342b">https://gist.github.com/alanorth/72a70aca856d76f24c127a6e67b3342b</a></li>
<li>Discuss metadata renaming with Abenet, we decided it’s better to start with the center-specific subjects like ILRI, CIFOR, CCAFS, IWMI, and CPWF</li>
<li>I’ve e-mailed CCAFS and CPWF people to ask them how much time it will take for them to update their systems to cope with this change</li>
<li>Looking at the DOI issue <ahref="https://www.yammer.com/dspacedevelopers/#/Threads/show?threadId=678507860">reported by Leroy from CIAT a few weeks ago</a></li>
<li>It seems the <code>dx.doi.org</code> URLs are much more proper in our repository!</li>

<li>I will manually edit the <code>dc.identifier.doi</code> in <ahref="https://cgspace.cgiar.org/handle/10568/72509?show=full"><sup>10568</sup>⁄<sub>72509</sub></a> and tweet the link, then check back in a week to see if the donut gets updated</li>
<li>The donut is already updated and shows the correct number now</li>
<li>CCAFS people say it will only take them an hour to update their code for the metadata renames, so I proposed we’d do it tentatively on Monday the 18th.</li>
