<li>Also, the disk is nearly full because of log file issues, so I’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’ve just compressed anything older than 2 weeks so we can get some disk space back</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>
|
|
</ul>
|
|
|
|
<pre><code># These GC settings have shown to work well for a number of common Solr workloads

<li>I need to try these because they are recommended by the Solr project itself</li>
|
|
<li>Also, as always, I need to read <a href="https://wiki.apache.org/solr/ShawnHeisey">Shawn Heisey’s wiki page on Solr</a></li>

|
|
<li>I did some basic benchmarking on a local DSpace before and after the JVM settings above, but there wasn’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’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>
|
|
<li>Atmire responded about the MQM warnings in the DSpace logs</li>
|
|
<li>Apparently we need to change the batch edit consumers in <code>dspace/config/dspace.cfg</code>:</li>
