Error while configuring multiple repositories

Ravindra_Nalavd — Fri, 11 Oct 2019 14:10:15 GMT

I want to create second repository in Nuxeo Multiple Repositories Configuration as given in the documentation, I have updated nuxeo.conf file also updated datasources-secondrepo-config.xml and `repository-secondrepo-config.xml.

Following are the configurations files that I have added manually in $NUXEO_HOME/nxserver/config directory

datasources-secondrepo-config.xml

	<?xml version="1.0"?>
	<component name="datasources-secondrepo-config">
	
	  <extension target="org.nuxeo.runtime.datasource" point="datasources">
	    <datasource name="jdbc/repository_secondrepo" xaDataSource="org.postgresql.xa.PGXADataSource"
	      maxPoolSize="100" minPoolSize="5" blockingTimeoutMillis="10000">
	        <property name="ServerName">10.43.11.77</property>
	        <property name="PortNumber">5432</property>
	        <property name="DatabaseName">secondrepo</property>
	        <property name="User">postgres</property>
	        <property name="Password">admin</property>
	    </datasource>
	  </extension>
	  
	  <link name="jdbc/secondrepo_keyvaluestore" global="jdbc/repository_secondrepo" type="javax.sql.DataSource" />
	</component>

repository configuration in

repository-secondrepo-config.xml

<?xml version="1.0"?>

    </store>
  </extension>

</component>

In PostgreSQL DB I have added the following properties

max_prepared_transactions = 100

When I start Nuxeo server, I am getting following error logs, although second repository is working fine, All CRUD operations are also working as expected. Am I missing some property or configuration?

If you have a setup meeting https://doc.nuxeo.com/nxdoc/jdbc-datasource/#accessing-multiple-databases in addition to https://doc.nuxeo.com/nxdoc/postgresql/#two-phase-commit , then you might have hit an unwanted situation, either from Nuxeo or PG or Apache. If the documentations links above do not help, try opening a Jira ticket?
