Peter gave feedback on the dc.rights proof of concept that I had sent him last week
|
|
We don’t need to distinguish between internal and external works, so that makes it just a simple list
|
|
Yesterday I figured out how to monitor DSpace sessions using JMX
|
|
I copied the logic in the jmx_tomcat_dbpools provided by Ubuntu’s munin-plugins-java package and used the stuff I discovered about JMX in 2018-01

<li>Bram from Atmire responded about the high load caused by the Solr updater script and said it will be fixed with the updates to DSpace 5.8 compatibility: <a href="https://tracker.atmire.com/tickets-cgiar-ilri/view-ticket?id=566">https://tracker.atmire.com/tickets-cgiar-ilri/view-ticket?id=566</a></li>

<li>We will close that ticket for now and wait for the 5.8 stuff: <a href="https://tracker.atmire.com/tickets-cgiar-ilri/view-ticket?id=560">https://tracker.atmire.com/tickets-cgiar-ilri/view-ticket?id=560</a></li>

<li>I finally took a look at the second round of cleanups Peter had sent me for author affiliations in mid January</li>
|
|
<li>After trimming whitespace and quickly scanning for encoding errors I applied them on CGSpace:</li>
|
|
</ul>
|
|
|
|
<pre><code>$ ./delete-metadata-values.py -i /tmp/2018-02-03-Affiliations-12-deletions.csv -f cg.contributor.affiliation -m 211 -d dspace -u dspace -p 'fuuu'
|
|
$ ./fix-metadata-values.py -i /tmp/2018-02-03-Affiliations-1116-corrections.csv -f cg.contributor.affiliation -t correct -m 211 -d dspace -u dspace -p 'fuuu'
|
|
</code></pre>
|
|
|
|
<ul>
|
|
<li>Then I started a full Discovery reindex:</li>
|
|
</ul>
|
|
|
|
<pre><code>$ time schedtool -D -e ionice -c2 -n7 nice -n19 [dspace]/bin/dspace index-discovery -b

<ul>
|
|
<li>Generate a new list of affiliations for Peter to sort through:</li>
|
|
</ul>
|
|
|
|
<pre><code>dspace=# \copy (select distinct text_value, count(*) as count from metadatavalue where metadata_field_id = (select metadata_field_id from metadatafieldregistry where element = 'contributor' and qualifier = 'affiliation') AND resource_type_id = 2 group by text_value order by count desc) to /tmp/affiliations.csv with csv;
|

COPY 3723

<ul>

<li>Oh, and it looks like we processed over 3.1 million requests in January, up from 2.9 million in <a href="/cgspace-notes/2017-12/">December</a>:</li>

<ul>
|

<li>Toying with correcting authors with trailing spaces via PostgreSQL:</li>
|
|
</ul>
|
|
|
|
<pre><code>dspace=# update metadatavalue set text_value=REGEXP_REPLACE(text_value, '\s+$' , '') where resource_type_id=2 and metadata_field_id=3 and text_value ~ '^.*?\s+$';
|
|
UPDATE 20
|
|
</code></pre>
|
|
|
|
<ul>
|
|
<li>I tried the <code>TRIM(TRAILING from text_value)</code> function and it said it changed 20 items but the spaces didn’t go away</li>
|
|
<li>This is on a fresh import of the CGSpace database, but when I tried to apply it on CGSpace there were no changes detected. Weird.</li>
|
|
<li>Anyways, Peter wants a new list of authors to clean up, so I exported another CSV:</li>
|
|
</ul>
|
|
|
|
<pre><code>dspace=# \copy (select distinct text_value, count(*) as count from metadatavalue where metadata_field_id = (select metadata_field_id from metadatafieldregistry where element = 'contributor' and qualifier = 'author') AND resource_type_id = 2 group by text_value order by count desc) to /tmp/authors-2018-02-05.csv with csv;

COPY 55630
