2.5.6. Database Configuration

Procedure 2.3. Configure Database

1. Create DefaultDS file

   Create a default DS file for the desired database. Examples of this file are located in JBOSS_HOME/docs/examples/jca.

   Important

   A DefaultDS file must be supplied in the JBOSS_HOME/server/production/deploy directory.

2. Delete HSQLDB files

   Delete the following files as they refer to the HSQLDB database:
   • JBOSS_HOME/server/production/deploy/hsqldb-ds.xml
   • JBOSS_HOME/common/lib/hsqldb.jar
   • JBOSS_HOME/common/lib/hsqldb-plugin.jar
   • JBOSS_HOME/server/production/deploy/messaging/hsqldb-persistence-service.xml

3. Remove HSQLDB Security Domain

   Comment out the security domain for HsqlDbRealm in the JBOSS_HOME/server/production/conf/login-config.xml file as shown.

   <!-- Security domains for testing new jca framework
   <application-policy name = "HsqlDbRealm">
     <authentication>
       <login-module 
         code = "org.jboss.resource.security.ConfiguredIdentityLoginModule" 
         flag = "required">
         <module-option name = "principal">sa</module-option>
         <module-option name = "userName">cctest</module-option>
         <module-option name = "password">cc1248</module-option>
         <module-option name = "managedConnectionFactoryName">
           jboss.jca:service=LocalTxCM,name=DefaultDS
         </module-option>
       </login-module>
     </authentication>
   </application-policy>
   -->
   

4. Copy persistence service configuration file

   The [database]-persistence-service.xml file contains the persistence service definition for JBoss Messaging, for the database specified by the [database] in the filename.
   Copy the [database]-persistence-service.xml file that corresponds to the database you are using from the JBOSS_HOME/docs/examples/jms directory to JBOSS_HOME/server/production/deploy.

   Note

   The table definitions in any [database]-persistence-service.xml are not optimized for performance.

5. Relocate JDBC driver libraries

   Place the supported JDBC driver libraries in the directory JBOSS_HOME/server/production/lib/.

   Important

   Ensure you follow the policy guidelines in Section 2.5.5, “Java Security Manager Policy File ” and choose a supported JDBC driver from Table 2.1, “Allowed 5.1.0 Database and JDBC Driver Versions” or Table 2.2, “Allowed 5.1.1 Database and JDBC Driver Versions”to maintain an evaluated configuration.

6. Add JDBC Grant Statement

   Add the following grant statement for the JDBC driver you are using to the Java Security Manager policy file. The policy file is located in JBOSS_HOME/bin/security_cc.policy. Substitute the directory name of the JDBC driver where [cc.jdbc.driver] is specified in the code sample.

   Important

   Each JDBC driver can use different permissions. Check the JDBC driver documentation and replace java.security.AllPermission; with a secure permission scheme supported by the driver.

   // granting permissions to JDBC driver 
   grant codeBase "file:${jboss.server.home.dir}/lib/[cc.jdbc.driver]" { 
     permission java.security.AllPermission; 
   };

7. Oracle Database Persistence Plugin Optimization

   When using the Oracle Database, the database persistence plugin definition must be changed in JBOSS_HOME/server/production/deploy/ejb2-timer-service.xml from being:

   <attribute name="DatabasePersistencePlugin">
   org.jboss.ejb.txtimer.GeneralPurposeDatabasePersistencePlugin
   </attribute>

   to being:

   <attribute name="DatabasePersistencePlugin">
   org.jboss.ejb.txtimer.OracleDatabasePersistencePlugin
   </attribute>
