Configure Bloomreach Experience Manager for PostgreSQL

Introduction

Goal

Configure Bloomreach Experience Manager's content repository and the Tomcat application container to use a PostgreSQL database.

Background

This page assumes you've read the parent page on configuring databases for Hippo, if you haven't done so already, please start there. That page in turn assumes you're following the Linux installation manual. This page will contain some basic database specific information, and example configurations for use in that scenario.

Text

Configuration changes

Datasource

URL

• jdbc:postgresql://DBHOST:DBPORT/DBNAME

Driver

•  org.postgresql.Driver

Validationquery

• SELECT 1

Repository

To use PostgreSQL the repository configuration needs to be changed to use a couple of database specific changes. Below we provide complete example configuration for the most common uses.

It's needed to set the correct databaseType & classes for the FileSystems, Persistencemanagers, Journal & Datastore.

• databaseType

  • postgresql

• FileSystem class

  • org.apache.jackrabbit.core.fs.db.DbFileSystem

• PersistenceManager class

  • org.apache.jackrabbit.core.persistence.pool.PostgreSQLPersistenceManager

• Journal class

  • org.apache.jackrabbit.core.journal.DatabaseJournal

• DataStore class

  • org.apache.jackrabbit.core.data.db.DbDataStore

Example JNDI resource:

Typically, this is defined in Tomcat's conf/context.xml.

    <Resource
                name="jdbc/repositoryDS" auth="Container" type="javax.sql.DataSource"
                maxTotal="20" maxIdle="10" initialSize="2" maxWaitMillis="10000"
                testWhileIdle="true" testOnBorrow="false" validationQuery="SELECT 1"
                timeBetweenEvictionRunsMillis="10000"
                minEvictableIdleTimeMillis="60000"
                username="DBUSER" password="DBPASS"
                driverClassName="org.postgresql.Driver"
                url="jdbc:postgresql://DBHOST:DBPORT/DBNAME" />

Example repository.xml for Repository Consistency Checker:

The Repository Consistency Checker requires its own repository.xml configuration file. Below is an example for PostgreSQL:
