OpenJMS 6 Under the Sonic installation root directory, /jms/sonic, edit database configuration file db.ini. Set property ENABLE_SECURITY to false and save. 7 Open a Command Prompt window and navigate to the /jms/sonic/bin directory, and issue the command dbtool/r all to reinitialize the database. For UNIX use the command dbtool -r all 8 The Sonic JMS broker can now be restarted. The Broker will now run with security disabled. To establish a connection in the Sonic Management Console should not require user/password authentication now. OpenJMS OpenJMS is tied to the lifecycle of a BES partition. BES contains a complete footprint of OpenJMS. OpenJMS provides the following added value: ■ Transparent Installation ■ Support for automatic table creation ■ Out-of-box integration with BES's Naming Service (JNDI), Transaction Service and Datasource ■ ■ Provides partition-level service management Support for RMI connector using VisiBroker ■ Lifecycle management using <strong>Borland</strong> Management Console When you install BES AppServer Edition with OpenJMS in BES version 6.5, OpenJMS comes packaged as a partition level template. This means that partitions created from this template get OpenJMS as an in-process service. The following properties in the partition template are set to true by default when you install BES AppServer Edition with OpenJMS: ■ ejb.mdb.use_jms_threads=true ■ ■ This property is needed to allow the transaction that was started by OpenJMS to propagate into BES ejb.mdb.local_transaction_optimization=true This property is needed to allow the use of non-XA JMS connection factories to be used in transactional scenarios. If not set, the MDBs that have transaction onMessage method will fail to deploy jts.allow_unrecoverable_completion=true By default, BES uses the JDataStore database for message persistence. If your application database is different from your message persistence database, you will need to set this property to true in order to achieve the two phase commit. Refer to Chapter 31, “EJB, JSS, and JTS Properties” for more information on each of the properties. Chapter 24: JMS provider pluggability 229
OpenJMS Even though OpenJMS can be used in a standalone mode where it is the only service in the partition, there are some advantages to using OpenJMS as an in-process service: ■ ■ It helps avoid the two-phase commit (2PC), and hence the performance cost and deployment complexity associated with it. This involves JDBC connection sharing among different components in the partition that access the database. It can be achieved by making OpenJMS persist messages in the same database as the one in which application data is stored. This configuration where 2PC can be avoided is possible only when OpenJMS is accessed through its embedded or RMI connector inside the BES partition. See “Configuring Datasource to Achieve 2PC Optimization” on page 232 for details. Since all the components are centralized in a single virtual machine, you can avoid the cost of TCP/IP. The JMS client library calls an in-process JMS service using regular Java call and vice versa. ■ Since VBJ provides local call optimizations, the application won't need to have two types of connectors. It can use only the RMI connector irrespective of client location with respect to the JMS <strong>server</strong>. You can find the OpenJMS product documentation in the /jms/openjms/ docs directory. Configuring JNDI objects for OpenJMS Note Since each partition in BES can host an instance of OpenJMS, there is a dedicated configuration file, openjms.xml, for each partition. The openjms.xml file contains information about various OpenJMS connectors and JNDI objects that the instance hosts. BES does not support the administration GUI in OpenJMS. You can create and delete queues for OpenJMS by editing the openjms.xml file. To add new Queues, Topics or Connection Factories for OpenJMS, you must modify its configuration file, openjms.xml. To access this file: 1 Select the relevant partition in the left pane. 2 Right-click on the OpenJMS service in the left pane. 3 Select Properties from the drop-down menu. 4 Click on the openjms.xml tab in the right pane to bring it forward. 5 Edit the file to add the JNDI objects. See the OpenJMS documentation in the /jms/openjms/docs directory for more details on this file. The code sample below shows you how to add a Queue and a Topic connection factory. ■ ■ ■ ■ You can add any number of factories as necessary for your application. Make sure that each object you add has a unique name so as to avoid being overwritten in JNDI. The name has to be unique among multiple instances. You must have at least one TopicConnectionFactory and one QueueConnectionFactory in the embedded scheme. If you do not specify a port for the connector, the default port will be used. Refer to the OpenJMS documentation for details located in /jms/openjms/docs. 230 BES Developer’s Guide
