<ul>

<li>I checked IITA's 259 Feb 14 records from last month for duplicates using Atmire's Duplicate Checker on a fresh snapshot of CGSpace on my local machine and everything looks good</li>
|
||
<li>I am now only waiting to hear from her about where the items should go, though I assume Journal Articles go to IITA Journal Articles collection, etc…</li>
|
||
<li>Looking at the other half of Udana's WLE records from 2018-11
|
||
<ul>
|
||
<li>I finished the ones for Restoring Degraded Landscapes (RDL), but these are for Variability, Risks and Competing Uses (VRC)</li>
|
||
<li>I did the usual cleanups for whitespace, added regions where they made sense for certain countries, cleaned up the DOI link formats, added rights information based on the publications page for a few items</li>
|
||
<li>Most worryingly, there are encoding errors in the abstracts for eleven items, for example:</li>
|
||
<li>68.15% <20> 9.45 instead of 68.15% ± 9.45</li>
|
||
<li>2003<EFBFBD>2013 instead of 2003–2013</li>
|
||
</ul>
|
||
</li>
|
||
<li>I think I will need to ask Udana to re-copy and paste the abstracts with more care using Google Docs</li>

</code></pre><ul>
|
||
<li>Judging from the time of the crash it was probably related to the Discovery indexing that starts at midnight</li>
|
||
<li>From the DSpace log I see that eventually Solr stopped responding, so I guess the <code>java</code> process that was OOM killed above was Tomcat's</li>
|
||
<li>I'm not sure why Tomcat didn't crash with an OutOfMemoryError…</li>
|
||
<li>Anyways, perhaps I should increase the JVM heap from 5120m to 6144m like we did a few months ago when we tried to run the whole CGSpace Solr core</li>
|
||
<li>The server only has 8GB of RAM so we'll eventually need to upgrade to a larger one because we'll start starving the OS, PostgreSQL, and command line batch processes</li>
|
||
<li>I ran all system updates on DSpace Test and rebooted it</li>
|
||
</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.

||
