<li>It says 732 bitstreams have potential issues, for example:</li>
<li>The first one seems ok, but I don’t know what to make of the second one…</li>
<li>I had a look and there is indeed no file with the second checksum in the assetstore (ie, looking in <code>[dspace-dir]/assetstore/99/59/30/...</code>)</li>
<li>For what it’s worth, there is no item on DSpace Test or S3 backups with that checksum either…</li>
<li>In other news, I’m looking at JVM settings from the Solr 4.10.2 release, from <code>bin/solr.in.sh</code>:</li>

<li>More work on the KM4Dev Journal article</li>
<li>In other news, it seems the batch edit patch is working, there are no more WARN errors in the logs and the batch edit seems to work</li>
<li>I need to check the CGSpace logs to see if there are still errors there, and then deploy/monitor it there</li>
<li>Paola from CCAFS mentioned she also has the “take task” bug on CGSpace</li>
<li>Reading about <ahref="https://www.postgresql.org/docs/9.5/static/runtime-config-resource.html"><code>shared_buffers</code> in PostgreSQL configuration</a> (default is 128MB)</li>
<li>Looks like we have ~5GB of memory used by caches on the test server (after OS and JVM heap!), so we might as well bump up the buffers for Postgres</li>
<li>The docs say a good starting point for a dedicated server is 25% of the system RAM, and our server isn’t dedicated (also runs Solr, which can benefit from OS cache) so let’s try 1024MB</li>
<li>In other news, the authority reindexing keeps crashing (I was manually running it after the author updates above):</li>

<li>For what it’s worth, after running the same SQL updates on my local test server, <code>index-authority</code> runs and completes just fine</li>
<li>I will have to test more</li>
<li>Anyways, I noticed that some of the authority values I set actually have versions of author names we don’t want, ie “Grace, D.”</li>
<li>For example, do a Solr query for “first_name:Grace” and look at the results</li>
<li>Querying that ID shows the fields that need to be changed:</li>
"msg":"Unexpected character '[' (code 91) in prolog; expected '<'\n at [row,col {unknown-source}]: [1,1]",
"code":400}}
</code></pre>
<ul>
<li>When I try using the XML format I get an error that the <code>updateLog</code> needs to be configured for that core</li>
<li>Maybe I can just remove the authority UUID from the records, run the indexing again so it creates a new one for each name variant, then match them correctly?</li>
</ul>

UPDATE 561
</code></pre>
<ul>
<li>Then I’ll reindex discovery and authority and see how the authority Solr core looks</li>
<li>After this, now there are authorities for some of the “Grace, D.” and “Grace, Delia” text_values in the database (the first version is actually the same authority that already exists in the core, so it was just added back to some text_values, but the second one is new):</li>
<li>So now I could set them all to this ID and the name would be ok, but there has to be a better way!</li>
<li>In this case it seems that since there were also two different IDs in the original database, I just picked the wrong one!</li>
<li>Better to use:</li>
</ul>
<pre><code>dspace#= update metadatavalue set text_value='Grace, Delia', authority='bfa61d7c-7583-4175-991c-2e7315000f0c', confidence=600 where resource_type_id=2 and metadata_field_id=3 and text_value like 'Grace, D%';
</code></pre>
<ul>
<li>This proves that unifying author name varieties in authorities is easy, but fixing the name in the authority is tricky!</li>
<li>Perhaps another way is to just add our own UUID to the authority field for the text_value we like, then re-index authority so they get synced from PostgreSQL to Solr, then set the other text_values to use that authority ID</li>

<ul>
<li>It seems that, when you are messing with authority and author text values in the database, it is better to run authority reindex first (postgres→solr authority core) and then Discovery reindex (postgres→solr Discovery core)</li>
<li>Everything looks ok after authority and discovery reindex</li>
<li>In other news, I think we should really be using more RAM for PostgreSQL’s <code>shared_buffers</code></li>
<li>The <ahref="https://www.postgresql.org/docs/9.5/static/runtime-config-resource.html">PostgreSQL documentation</a> recommends using 25% of the system’s RAM on dedicated systems, but we should use a bit less since we also have a massive JVM heap and also benefit from some RAM being used by the OS cache</li>

<ul>
<li>Checking in on CGSpace postgres stats again, looks like the <code>shared_buffers</code> change from a few days ago really made a big impact:</li>
<li>Looking at logs, it seems we need to evaluate which logs we keep and for how long</li>
<li>Basically the only ones we <em>need</em> are <code>dspace.log</code> because those are used for legacy statistics (need to keep for 1 month)</li>
<li>Other logs will be an issue because they don’t have date stamps</li>
<li>I will add date stamps to the logs we’re storing from the tomcat7 user’s cron jobs at least, using: <code>$(date --iso-8601)</code></li>
<li>Would probably be better to make custom logrotate files for them in the future</li>
<li>Clean up some unneeded log files from 2014 (they weren’t large, just don’t need them)</li>
<li>So basically, new cron jobs for logs should look something like this:</li>
<li>Find any file named <code>*.log*</code> that isn’t <code>dspace.log*</code>, isn’t already zipped, and is older than one day, and zip it:</li>
<li>Since there is <code>xzgrep</code> and <code>xzless</code> we can actually just zip them after one day, why not?!</li>
<li>We can keep the zipped ones for two weeks just in case we need to look for errors, etc, and delete them after that</li>
<li>I use <code>schedtool -B</code> and <code>ionice -c2 -n7</code> to set the CPU scheduling to <code>SCHED_BATCH</code> and the IO to best effort which should, in theory, impact important system processes like Tomcat and PostgreSQL less</li>
<li>When the tasks are running you can see that the policies do apply:</li>

<li>Start planning for server migration this weekend, letting users know</li>
<li>I am trying to figure out what the process is to <ahref="http://handle.net/hnr_support.html">update the server’s IP in the Handle system</a>, and emailing the hdladmin account bounces(!)</li>
<li>I will contact the Jane Euler directly as I know I’ve corresponded with her in the past</li>
<li>She said that I should indeed just re-run the <code>[dspace]/bin/dspace make-handle-config</code> command and submit the new <code>sitebndl.zip</code> file to the CNRI website</li>
<li>Also I was troubleshooting some workflow issues from Bizuwork</li>
<li>I re-created the same scenario by adding a non-admin account and submitting an item, but I was able to successfully approve and commit it</li>
<li>So it turns out it’s not a bug, it’s just that Peter was added as a reviewer/admin AFTER the items were submitted</li>
<li>This is how DSpace works, and I need to ask if there is a way to override someone’s submission, as the other reviewer seems to not be paying attention, or has perhaps taken the item from the task pool?</li>
<li>Run a batch edit to add “RANGELANDS” ILRI subject to all items containing the word “RANGELANDS” in their metadata for Peter Ballantyne</li>
</ul>
<p><imgsrc="/cgspace-notes/2016/12/batch-edit1.png"alt="Select all items with "rangelands" in metadata"/>
<li>Add four new CRP subjects for 2017 and sort the input forms alphabetically (<ahref="https://github.com/ilri/DSpace/pull/294">#294</a>)</li>
<li>Test the SMTP on the new server and it’s working</li>
<li>Last week, when we asked CGNET to update the DNS records this weekend, they misunderstood and did it immediately</li>
<li>We quickly told them to undo it, but I just realized they didn’t undo the IPv6 AAAA record!</li>
<li>None of our users in African institutes will have IPv6, but some Europeans might, so I need to check if any submissions have been added since then</li>
<li>Update some names and authorities in the database:</li>

<ul>
<li>Generated a new UUID for Ben using <code>uuidgen | tr [A-Z] [a-z]</code> as the one in Solr had his ORCID but the name format was incorrect</li>

<li>I need to run these updates along with the other one for CIAT that I found last week</li>
