Some components of Eclipse SCADA can work with a relational database.

Basic Information

All further examples assume that:

  • the database name is "eclipsescada"
  • the database user is "eclipsescada"
  • the password is "eclipsescada"

JDBC Driver

Eclipse SCADA uses the OSGi Enterprise method of obtaining a JDBC driver in an OSGi environment. This requires to have a JDBC driver that supports the OSGi enterprise specification. Otherwise you can take a normal JDBC driver and create a wrapper bundle which implements the DataSourceFactory interface.

Also see:

Gemini DBAccess –
The Gemini DBAcess project provides OSGi Enterprise compliant JDBC drivers. At the moment they have drivers for MySQL, H2 and Derby
openSCADA –
The openSCADA project provides a wrapper bundle for the Postgres JDBC driver. The bundle is called "org.openscada.external.postgresql" and is contained in the "external" repostory.
See for the P2 archive and a ZIP archive
See and for .deb or .rpm versions of the archive


If you want to use Postgres you will need to install the following packages:


zypper install postgresql92 postgresql92-server postgresql92-contrib


A&E stores event data in a relational database. It provides two storage formats.

Plain SQL

This storage format stores everything using plain SQL statements. Is is very portable but not as performant.

Table structure

Postgres specific

See the setup script at [1]

Download the file and execute it as postgres user:

sudo su - postgres
psql -f create.postgresql.sql -declipsescada

The script will install a set of postgres extensions (from the contrib package) and therefore requires database admin privileges.


If it is not possible for you, some services provide an alternate method of persistence.

  • The CA provides a file based storage
