<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>In other news, I think we should really be using more RAM for PostgreSQL’s <code>shared_buffers</code></li>

<li>The <a href="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>

<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>Clean up some unneeded log files from 2014 (they weren’t large, just don’t need them)</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>It took about twenty minutes and afterwards I had to check a few things, like:
|
|
<ul>
|
|
<li>check and enable systemd timer for let’s encrypt</li>
|
|
<li>enable root cron jobs</li>
|
|
<li>disable root cron jobs on old server after!</li>
|
|
<li>enable tomcat7 cron jobs</li>
|
|
<li>disable tomcat7 cron jobs on old server after!</li>
|
|
<li>regenerate <code>sitebndl.zip</code> with new IP for handle server and submit it to Handle.net</li>
|
|
</ul>

<li>Abenet wanted a CSV of the IITA community, but the web export doesn’t include the <code>dc.date.accessioned</code> field</li>

<li>I had to export it from the command line using the <code>-a</code> flag:</li>

|
<li>We’ve been getting two alerts per day about CPU usage on the new server from Linode</li>
|
|
<li>These are caused by the batch jobs for Solr etc that run in the early morning hours</li>
|
|
<li>The Linode default is to alert at 90% CPU usage for two hours, but I see the old server was at 150%, so maybe we just need to adjust it</li>
|
|
<li>Speaking of the old server (linode01), I think we can decommission it now</li>
|
|
<li>I checked the S3 logs on the new server (linode18) to make sure the backups have been running and everything looks good</li>
|
|
<li>In other news, I was looking at the Munin graphs for PostgreSQL on the new server and it looks slightly worrying:</li>
