<li>DSpace&rsquo;s own Solr logs don&rsquo;t give IP addresses, so I will have to enable Nginx&rsquo;s logging of <code>/solr</code> so I can see where this request came from</li>

<li>Also, the disk is nearly full because of log file issues, so I&rsquo;m running some compression on DSpace logs</li>
<li>Normally these stay uncompressed for a month just in case we need to look at them, so now I&rsquo;ve just compressed anything older than 2 weeks so we can get some disk space back</li>

<li>The first one seems ok, but I don&rsquo;t know what to make of the second one&hellip;</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>I did some basic benchmarking on a local DSpace before and after the JVM settings above, but there wasn&rsquo;t anything amazingly obvious</li>
<li>I want to make the changes on DSpace Test and monitor the JVM heap graphs for a few days to see if they change the JVM GC patterns or anything (munin graphs)</li>
<li>Spin up new CGSpace server on Linode</li>
<li>I did a few traceroutes from Jordan and Kenya and it seems that Linode&rsquo;s Frankfurt datacenter is a few less hops and perhaps less packet loss than the London one, so I put the new server in Frankfurt</li>
<li>Do initial provisioning</li>

<ul>
<li>Pay attention to the regex to prevent false positives in tricky cases with Dutch names!</li>
<li>I will run these updates on DSpace Test and then force a Discovery reindex, and then run them on CGSpace next week</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 &ldquo;take task&rdquo; bug on CGSpace</li>
2016-12-07 12:55:16 +01:00
<li>Reading about <a href="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&rsquo;t dedicated (also runs Solr, which can benefit from OS cache) so let&rsquo;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&rsquo;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&rsquo;t want, ie &ldquo;Grace, D.&rdquo;</li>
<li>For example, do a Solr query for &ldquo;first_name:Grace&rdquo; and look at the results</li>
<li>Querying that ID shows the fields that need to be changed:</li>

<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>Then I&rsquo;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 &ldquo;Grace, D.&rdquo; and &ldquo;Grace, Delia&rdquo; 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>
<li>This proves that unifying author name varieties in authorities is easy, but fixing the name in the authority is tricky!</li>
2016-12-07 12:58:00 +01:00
<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>
