WebSphere Enterprise Service Bus for z/OS, Version 6.2.0 Operating Systems: z/OS


Planning for a deployment environment based on one of the supplied patterns

Use this scenario when you have scalability, availability and quality of service requirements for Service Component Architecture (SCA) applications that can be met with one of the IBM-supplied patterns.

Before you begin

Familiarize yourself with the information about these topics and any related topics, if you have not done so already.

Diagram what hardware you are using for your deployment environment and indicate what server each piece of equipment hosts. Also indicate which servers will provide the deployment environment functions so you have a clearer idea of how to cluster the servers together.

About this task

You have analyzed your business needs and determined that a single server is insufficient to meet your needs. You need multiple servers to provide high availability, and failover. Your design fits one of the IBM-supplied deployment environment patterns.
Procedure
  1. Determine the hardware and software you need to support your design.
  2. Select the database product to support the deployment environment.

    Some systems, such as z/OS and i5/OS do not have automated methods to create databases and tables for messaging engines and Common Event Infrastructure (CEI). When creating databases for these systems, make sure you have sufficient authorization to run database definition scripts successfully.

    Important: If your future plans include federating this environment into a deployment manager cell, make sure that you use a database and database drivers that support remote access. Examples of these types of products are Derby Network and Java toolbox JDBC.
  3. Decide how you create the database tables.

    Either create the tables during product installation, have the product install process create scripts to create the tables for you, or create scripts yourself to perform this step.

  4. Decide which IBM-supplied pattern best fits your design.
  5. Map the servers as members of the cluster that provides the function you identified in your design.

    The pattern you select will map nodes to clusters and will determine the number of members and their distribution.

  6. Decide how clients are to access the applications in the deployment environment.

    Based on your needs there are many ways to access including Web services (SOAP/HTTP and SOAP/JMS), synchronous or asynchronous Service Component Architecture (SCA) requests, Java™ Message Service (JMS), MQ (either JMS or native), or through adapters. These choices impact what other software and resources you must install.

  7. Decide how the applications access any resources they require.

    Based on your needs there are many ways to access including Web services (SOAP/HTTP and SOAP/JMS), synchronous or asynchronous Service Component Architecture (SCA) requests, Java Message Service (JMS), MQ (either JMS or native), or through adapters. These choices impact what other software and resources you must install.

  8. Decide how to install the software, create the servers and configure the created servers.

    You can create and configure servers while installing the software or you can create and configure servers using the Profile Management Tool. You can also use the administrative console or scripts to create and configure servers. Understand the benefits and drawbacks of all methods before making a choice.

  9. Decide how any servers created on the same hardware will share the resources on that system.

    You can either install the software into separate locations, use different profiles, or, on i5/OS® use different logical partitions to accomplish the sharing.

  10. Identify or create any user IDs with the authorization you need to complete installation.

What to do next

Install your deployment environment.
