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

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?
