For PostgreSQL

(See "Metastore Database Requirements" and "Installing and Configuring PostgreSQL" in Chapter 1 of this guide.)

Create the Oozie user and Oozie database. For example, using the PostgreSQL psql command-line tool:

$ psql -U postgres
Password for user postgres: *****
postgres=# CREATE ROLE oozie LOGIN ENCRYPTED PASSWORD 'oozie'
NOSUPERUSER INHERIT CREATEDB NOCREATEROLE;
CREATE ROLE

postgres=# CREATE DATABASE "oozie" WITH OWNER = oozie
ENCODING = 'UTF8'
TABLESPACE = pg_default
LC_COLLATE = 'en_US.UTF8'
LC_CTYPE = 'en_US.UTF8'
CONNECTION LIMIT = -1;
CREATE DATABASE

postgres=# \q

Configure PostgreSQL to accept network connections for the oozie user. Edit the PostgreSQL data/pg_hba.conf file as follows:
host oozie oozie 0.0.0.0/0 md5
Reload the PostgreSQL configuration.
$ sudo -u postgres pg_ctl reload -s -D /opt/PostgresSQL/8.4/data

Configure Oozie to use PostgreSQL.

Edit the oozie-site.xml file as follows:

...
<property>
     <name>oozie.service.JPAService.jdbc.driver</name>
     <value>org.postgresql.Driver</value>
</property>

<property>
     <name>oozie.service.JPAService.jdbc.url</name>
     <value>jdbc:postgresql://localhost:5432/oozie</value>
</property>

<property>
     <name>oozie.service.JPAService.jdbc.username</name>
     <value>oozie</value>
</property>

<property>
     <name>oozie.service.JPAService.jdbc.password</name>
     <value>oozie</value>
</property>

	Note
	In the JDBC URL property, replace localhost with the hostname where PostgreSQL is running. For PostgreSQL it is unnecessary to download and install the JDBC driver separately because the driver is license-compatible and bundled with Oozie.
