Cost Because this option requires MQ Servers, it is one of most costly options. If you only use the MQ Client on the client application, you can cut the software cost in half. In terms of software development cost, this is one of least expensive options available. Data Type Centricity Tools

message delivery is guaranteed if you use MQ Servers on both sides of the connection. If you only use the MQ Client on the client application side, the message delivery is not guaranteed.

in the case of MQ enablement. If you are using the CICS Bridge, you must include an additional user ID/password pair in the message to the CICS transactions.

The IMS SOAP Gateway makes IMS applications accessible as Web Services through easy deployment and configuration steps. You don t have to change your IMS applications, but you do need to generate Web Services Definition Language (WSDL) files and XML converters using IBM WebSphere Developer for System z. The gateway usually runs on a separate machine (Windows, Linux, AIX), which can limit the scalability of this solution. The gateway communicates with the mainframe system using XML over TCP/IP. On the mainframe, the IMS Connect component with an XML adapter interacts with the IMS application through the use of Open Transaction Manager Access (OTMA), as shown in Figure 9.4. Here is a brief discussion of the various aspects of this approach of integrating mainframe applications to help you decide whether this option is suitable for your situation.

Work Required You can use WebSphere Developer for zSeries to easily generate the Web Services artifacts. For example, with WebSphere Developer for zSeries, you can generate a WSDL file from the COBOL copybook of an IMS application, which will also generate an XML

converter to transform XML data in IMS Connect. Then, the overall application can send and receive XML data, without you needing to modify your existing IMS applications. To use this functionality, you need APAR PK24912 applied to IMS V9.1.

Technology Constraints Requires IMS version 9 or higher, integrated with IMS Connect version 9. You need to be running z/OS on the mainframe. Real-Time Access and Synchronous/Asynchronous Messaging

Only syn-

Gateway runs on multiple platforms, including Microsoft Windows XP, Windows 2000, AIX, and zLinux. It usually runs on a machine separate from the one on which the application is running.

IMS Soap Gateway typically runs on a machine separate from the application. This machine can be running Windows XP, Windows 2000, or AIX, or it could be a mainframe running zLinux.

Security You can configure this solution for SSL to support secure com-

munication using HTTPS between the end client and IMS SOAP Gateway, as well as between the IMS SOAP Gateway and IMS Connect. This is an XML-centric solution.

Previously known as IMS Connector for Java (IC4J), the IMS TM Resource Adapter is a J2EE Connector Architecture based resource adapter you can deploy on the application server. It enables Java/J2EE and Web Services applications to access IMS applications on the mainframe through TCP/IP. The Java or J2EE application talks to the IMS applications through IMS Connect and OTMA, as shown in Figure 9.5. Therefore, IMS Connect and OTMA must be configured on the mainframe side. With this option, you can quickly develop Java/J2EE or Web Services applications that run IMS transactions. For development, Rational Application Developer can be employed. Application Developer parses copybook information to describe the input/output messages of a target

IMS application, and it generates a J2EE application. Application Developer can also generate WSDL so that the target IMS application can be exposed as a callable Web Services. Minimal work is required on the mainframe side. Here is a brief discussion of the various aspects of this approach of integrating mainframe applications to help you decide whether this option is suitable for your situation.

Work Required You don t need to change the IMS application. You can use IBM tooling to develop the J2EE or Web Services application. Then you can deploy the application on a J2EE application server such as WebSphere Application Server. Technology Constraints

z/OS is required on the mainframe. The IMS TM Resource Adapter runs in a WebSphere application on a number of platforms, including Windows, AIX, Linux, zLinux, and HP-UX. Messaging
