Planning the configuration of a messaging engine to use a data store

Use this task to plan the configuration of a messaging engine to use a data store.

Why and when to perform this task

Before you configure a messaging engine, consider the following steps:

Steps for this task

  1. Choose the relational database management system (RDBMS) for the data store. You might want to choose the RDBMS that you use for other applications, particularly if you are already familiar with the tools you use for managing that RDBMS. You might also want to consider the following criteria:
    • Performance
    • Scalability
    • Availability, especially if you are running messaging engines in a high availability environment

    When a new messaging engine is created on a single server, it is configured to use a Cloudscape data source by default, which enables the messaging engine to run without needing any additional configuration. The default embedded Cloudscape data source is sufficient for many purposes. Other relational database management systems offer more comprehensive tooling and improved performance, particularly scalability on larger machines with more than two processors.

  2. Choose your database topology. In some cases, running the data store on a remote node can improve performance. In other cases, a local database provides performance equivalent to a remote database. You might want to conduct your own performance analysis, because the performance characteristics can be very sensitive to the hardware specification.
  3. Consider whether you want WebSphere Application Server to create the data store tables automatically or whether you want your database administrator to create the tables beforehand. For more information, refer to Creating the tables.
