<ul>

|
<li>In Tomcat 8.5 the <code>removeAbandoned</code> property has been split into two: <code>removeAbandonedOnBorrow</code> and <code>removeAbandonedOnMaintenance</code></li>
|
|
<li>See: <a href="https://tomcat.apache.org/tomcat-8.5-doc/jndi-datasource-examples-howto.html#Database_Connection_Pool_(DBCP_2)_Configurations">https://tomcat.apache.org/tomcat-8.5-doc/jndi-datasource-examples-howto.html#Database_Connection_Pool_(DBCP_2)_Configurations</a></li>
|
|
<li>I assume we want <code>removeAbandonedOnBorrow</code> and make updates to the Tomcat 8 templates in Ansible</li>
|
|
<li>After reading more documentation I see that Tomcat 8.5’s default DBCP seems to now be Commons DBCP2 instead of Tomcat DBCP</li>
|
|
<li>It can be overridden in Tomcat’s <em>server.xml</em> by setting <code>factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"</code> in the <code><Resource></code></li>
|
|
<li>I think we should use this default, so we’ll need to remove some other settings that are specific to Tomcat’s DBCP like <code>jdbcInterceptors</code> and <code>abandonWhenPercentageFull</code></li>
|
|
<li>Merge the changes adding ORCID identifier to advanced search and Atmire Listings and Reports (<a href="https://github.com/ilri/DSpace/pull/371">#371</a>)</li>
|
|
<li>Fix one more issue of missing XMLUI strings (for CRP subject when clicking “view more” in the Discovery sidebar)</li>
|
|
<li>I told Udana to fix the citation and abstract of the one item, and to correct the <code>dc.language.iso</code> for the five Spanish items in his Book Chapters collection</li>
|
|
<li>Then we can import the records to CGSpace</li>
|
|
