Ingres 3.2


Updates


Preamble


This is the second tutorial with the subject 'Installing Alfresco & Ingres'. The first one can be found at Installing_Alfresco_Labs_3b_and_Ingres ( we will then use the link 1 for future references ) and describes very detailed how to install Alfresco 3.0 with Ingres. It is recommended to read it because the following tutorial will only explain the differences regarding Alfresco 3.2 and Ingres 10.


Installing Alfresco and Ingres


Alfresco 3.2


You should use Alfresco's GUI installer. The installation routine is quite the same as for Alfresco 3.0.


Ingres Database 10


The Community Edition of 'Ingres Database 10' can be downloaded from  http://esd.ingres.com .

-Attention please:- Please be aware of that Ingres 10 is still in development and is not generally available until now. So you should currently ( current date is 2009-08-24 ) not use it in production.

-Note:- The current GA version (Enterprise Edition) of Ingres is 9.2. It comes with full Enterprise Support. If you want to use Ingres with Alfresco in production you should use the Enterprise Edition. Please contact Ingres (products@ingres.com) for further information.


Installing using the 'ingbuild' tool


The previous article 1 explained how to perform an ingbuild installation completely manually. It is also possible to use the scripts those are part of the installation package. The current archive ( which means ingres-10.0.0-105-NPTL-gpl-pc-linux-ingbuild-i386.tgz ) contains two script files:


  • ingres_express_install.sh
  • install.sh

The 'ingres_express_install.sh' script performs a default installation by using e.G. the installation id II. You should use the 'install.sh' script to have more control on the parameters of your Ingres Database installation. It allows you to set:


  • Installation identifier
  • Time zone information
  • Character set (UTF8 or non UTF8)
  • ...

Please check the success of the installation as mentioned in 1.


Configuring Alfresco and Ingres


Ingres Database


The configuration of the Ingres DBMS works the same way as described in 1. You should use the configuration script which is attached there.


Create the database which will be used by Alfresco


The database schema differs. It will be created automatically during the first startup of Alfresco, but I will publish an optimized version for Ingres soon.


Alfresco


The way how to configure Alfresco 3.2 changed a bit. Instead the 'custom-respository.properties' file now the file '.../tomcat/shared/classes/alfresco-global.properties' should contain the configuration of the database connection. This new configuration file now also contains the Hibernate related configuration.



#
# Sample database connection properties
#-------------
db.name=alfresco
db.username=ingres
db.password=password_of_user_ingres
db.host=localhost
db.port=A37

#
# Ingres connection using Driver iijdbc.jar
#-------------
db.driver=com.ingres.jdbc.IngresDriver
db.url=jdbc:ingres://${db.host}:${db.port}/${db.name}
hibernate.dialect=org.hibernate.dialect.IngresDialect
hibernate.query.substitutions=true 1, false 0, yes 'Y', no 'N'

-Note:- Do not forget to add the Ingres JDBC driver to the Tomcat's lib directory!


Modify the content inside the Alfresco web application archive


This section contains the most important changes since Alfresco 3.0 . The alfresco.war file can be found at '.../tomcat/webapps/alfresco.war'(let's name it <alfresco.war>). It contains the following relevant folders/subfolders:


  • <alfresco.war>/WEB-INF/classes/alfresco/dbscripts
  • <alfresco.war>/WEB-INF/classes/alfresco/ibatis

Both folders contain data and scripts to generate the initial database schema. BTW: Ibatis is an O/R-mapper ( http://ibatis.apache.org ).


Database scripts

We are primarily interested in the scripts those are required to create the database. Therefore the folder '<alfresco.war>/WEB-INF/classes/alfresco/dbscripts/create' needs further investigation. The subfolders of this folder are related to the Alfresco versions. We are interested in the '3.0' and '3.2'. Each of this Alfresco version related folders contains subfolders named by the Hibernate dialect of the supported database systems. My installation of Alfresco 3.2 has only the folders 'org.hibernate.dialect.Dialect' (contains stuff which is the same for all DBMS) ,'org.hibernate.dialect.DerbyDialect' and 'org.hibernate.dialect.MySQLInnoDBDialect' (contains Derby/MySQL specific stuff). So let's add the Ingres specific stuff as well:

Ibatis mappings

The folder '<alfresco.war>/WEB-INF/classes/alfresco/ibatis' contains the following Ibatis configuration files:


  • activities-SqlMapConfig.xml
  • content-SqlMapConfig.xml
  • locks-SqlMapConfig.xml
  • ibatis-context.xml

It also contains subfolders named by the dialect of each natively supported DBMS. To add Ingres support the following steps must be performed:


  1. Add a folder named 'org.hibernate.dialect.IngresDialect'
  2. Copy everything from 'org.hibernate.dialect.Dialect' to 'org.hibernate.dialect.IngresDialect' (those are the *common*.xml map files)
  3. Modify the Ibatis configuration files mentioned above to use the folder 'org.hibernate.dialect.IngresDialect' instead 'org.hibernate.dialect.Dialect' for the lookup
  4. Create the following files with the following contents inside the folder 'org.hibernate.dialect.IngresDialect':
  • activities-insert-SqlMap.xml,
  • content-insert-SqlMap.xml
  • locks-insert-SqlMap.xml

Known issues


  • As mentioned before an optimized database schema is required and will be provided soon
  • Currently we gather the last inserted key value by using the 'max' function. This is a bit dirty and I can imagine possible problems caused by this way.
  • I found an issue with the 'Studio' application which comes with the Alfresco 3.2 Community Edition. I still have to find out if it is Ingres related. However, the Alfresco Web Client application seems to work.
