IA0L: MQSeries Integrator - Uuidgen Plug-In

Description

When building message flows with MQSeries Integrator V2, it is often desirable to be able to generate a unique value. Such a value might be used to initialise a MsgId or CorrelId field, or it could be used as the basis for a database key. The approach most customers have taken to solving this problem is to generate such values with an stand-alone application.

This SupportPac provides an alternative mechanism for generating a unique value within the broker environment. The UUID (Universally Unique Identifier) value generated is guaranteed to be unique among any other values also generated by the Uuidgen plug-in. The UUID value is a 16 byte (binary) value. The Uuidgen implementation is thread-safe and will work equally well for deployments where Message Flows have been configured with multiple worker threads.

Possible Uses

The SupportPac may be used to generate a unique value within an MQSeries Integrator V2 environment.

Prerequisites

The SupportPac requires:

• MQSeries Integrator V2.0.1, or V2.0.2 on AIX, HP-UX, Sun Solaris or Windows NT.

  or

• WebSphere MQ Integrator V2.1 on AIX, HP-UX, Sun Solaris, Windows NT or Windows 2000.

Notes:

1. The supplied .lil file is compatible with WebSphere MQ Integrator V2.1. However, the supplied source files are not and use of a .lil file produced as a result of compiling it in a WebSphere MQ Integrator environment is currently not supported.
2. For normal use, there are no other prerequisite products other than those required by MQSeries Integrator and WebSphere MQ Integrator. If any changes are to be made to the plug-in node, an appropriate C++ compiler is required.

Skill Level Required

To use the SupportPac, you need to be familiar with MQSeries Integrator. If the source is to be modified or recompiled, C++ language programming skills are required.
