Benefits of technology

[0009]According to a first aspect, the present invention provides a method for determining relationship data associated with application programs in a messaging system, comprising the steps of: responsive to at least one first message event sending a message from a first application to a first destination and at least one second message event retrieving, by a second application, the message from a second destination, intercepting message data associated with the message; analysing the intercepted message data in accordance with one or more rules in order to find one or more message parameters; and in response to finding the one or more message parameters, identifying the first message event and identifying the second message event, and determining a relationship associated with the first application and the second application.

Problems solved by technology

Although asynchronous messaging environments have advantages, understanding aspects about the environment, such as which application typically communicates with which other application(s), becomes very difficult.
However, this is a fairly intrusive mechanism and can have a detrimental effect on performance due to, for example, the size of the inserted data.
Once again, this is a fairly intrusive mechanism and has the added burden of requiring changes to the infrastructure which can be complex and error prone.
Furthermore, this approach is difficult to implement if a business does not have a full test environment that replicates a production environment.

Embodiment Construction

b class="d_n">[0013]FIG. 1A is a block diagram of a prior art messaging system;

[0014]FIG. 1B is a block diagram of an apparatus of the preferred embodiment in use with a prior art messaging system; and

[0015]FIG. 2 is a flow chart showing the operational steps involved in a process of the preferred embodiment.

DETAILED DESCRIPTION

[0016]A preferred embodiment will now be described with reference to the figures.

[0017]With reference to FIG. 1A, the preferred embodiment is implemented in a messaging system (100) comprising a plurality of application programs (105, 120) that intercommunicate using messages. The messages are communicated asynchronously between the application programs (105, 120) using destinations e.g. message queues (115, 130) each of which is managed by a message engine e.g., a queue manger (110, 125).

[0018]An application program can store (also known as “put”) messages on a queue and retrieve (also known as “get”) messages from a queue. For example, a first application (...

Abstract

A method for determining relationship data associated with application programs in a messaging system, comprising the steps of: responsive to at least one first message event sending a message from a first application to a first destination and at least one second message event retrieving, by a second application, the message from a second destination, intercepting message data associated with the message; analysing the intercepted message data in accordance with one or more rules in order to find one or more message parameters; and in response to finding the one or more message parameters, identifying the first message event and identifying the second message event, determining a relationship associated with the first application and the second application. An apparatus and computer program element for determining such relationship data are also provided.

Description

BACKGROUND[0001]1. Field:[0002]The present invention relates to a method for determining relationship data associated with application programs in a messaging system.[0003]2. Description of the Related Art[0004]Software client applications are often written as and when they are required. It is not uncommon for an application to be developed with little or no supporting documentation.[0005]Furthermore, some messaging environments (using a messaging product such as WebSphere MQ (WebSphere is a registered trademark of International Business Machines Corporation)) support asynchronous messaging resulting in a loose coupling between applications (e.g. in order to prevent an error associated with one application from holding up another application).[0006]Although asynchronous messaging environments have advantages, understanding aspects about the environment, such as which application typically communicates with which other application(s), becomes very difficult.[0007]There exist prior ar...
