It's more simple to configure a single-database data container. We have to configure one naming resource.

For example (embedded mode for jdbcjcr data container):

<external-component-plugins>

    <target-component>org.exoplatform.services.naming.InitialContextInitializer</target-component>

    <component-plugin>

        <name>bind.datasource</name>

        <set-method>addPlugin</set-method>

        <type>org.exoplatform.services.naming.BindReferencePlugin</type>

        <init-params>

          <value-param>

            <name>bind-name</name>

            <value>jdbcjcr</value>

          </value-param>

          <value-param>

            <name>class-name</name>

            <value>javax.sql.DataSource</value>

          </value-param>

          <value-param>

            <name>factory</name>

            <value>org.apache.commons.dbcp.BasicDataSourceFactory</value>

          </value-param>

          <properties-param>

            <name>ref-addresses</name>

            <description>ref-addresses</description>

            <property name="driverClassName" value="org.postgresql.Driver"/>

            <property name="url" value="jdbc:postgresql://exoua.dnsalias.net/portal"/>

            <property name="username" value="exoadmin"/>

            <property name="password" value="exo12321"/>

            <property name="maxActive" value="50"/>

            <property name="maxIdle" value="5"/>

            <property name="initialSize" value="5"/>

          </properties-param>

        </init-params>

    </component-plugin>

  </external-component-plugins>

  

And configure repository workspaces in repositories configuration with this one database. Parameter "multi-db" must be switched off (set value "false").

For example (two workspaces ws - jdbcjcr, ws1 - jdbcjcr):

<workspaces>

  <workspace name="ws" auto-init-root-nodetype="nt:unstructured">

    <container class="org.exoplatform.services.jcr.impl.storage.jdbc.JDBCWorkspaceDataContainer">

    <properties>

      <property name="source-name" value="jdbcjcr"/>

      <property name="dialect" value="pgsql"/>

      <property name="multi-db" value="false"/>

      <property name="max-buffer-size" value="200K"/>

      <property name="swap-directory" value="target/temp/swap/ws"/>

    </properties>

    </container>

    <cache enabled="true">

    <properties>

      <property name="max-size" value="10K"/>

      <property name="live-time" value="30m"/>

    </properties>

    </cache>

    <query-handler class="org.exoplatform.services.jcr.impl.core.query.lucene.SearchIndex">

    <properties>

      <property name="index-dir" value="../temp/index"/>

    </properties>

    </query-handler>

    <lock-manager>

    <time-out>15m</time-out>

    <persister class="org.exoplatform.services.jcr.impl.core.lock.FileSystemLockPersister">

      <properties>

      <property name="path" value="target/temp/lock/ws"/>

      </properties>

    </persister>

    </lock-manager>

  </workspace>

  <workspace name="ws1" auto-init-root-nodetype="nt:unstructured">

    <container class="org.exoplatform.services.jcr.impl.storage.jdbc.JDBCWorkspaceDataContainer">

    <properties>

      <property name="source-name" value="jdbcjcr"/>

      <property name="dialect" value="pgsql"/>

      <property name="multi-db" value="false"/>

      <property name="max-buffer-size" value="200K"/>

      <property name="swap-directory" value="target/temp/swap/ws1"/>

    </properties>

    </container>

    <cache enabled="true">

    <properties>

      <property name="max-size" value="10K"/>

      <property name="live-time" value="5m"/>

    </properties>

    </cache>

    <lock-manager>

    <time-out>15m</time-out>

    <persister class="org.exoplatform.services.jcr.impl.core.lock.FileSystemLockPersister">

      <properties>

      <property name="path" value="target/temp/lock/ws1"/>

      </properties>

    </persister>

    </lock-manager>

  </workspace>

</workspaces>

In this way, we have configured two workspaces which will be persisted in one database (PostgreSQL).
