Hi All,
We have been using Websphere Message broker v 6.1 in our project since 3 years and now we have migrated to version 8 also.
I wanted to know about the level at which the transformation/business logics can be applied in the ESQL code.
I wanted to know this because in most of the interface which we have developed we have been using simple business rules and it will be very fast but in some of the interface there is complex logic involved and the high volume/size message are processed and inserted into database or sent as XML outoput.
So here I wanted to know about Message broker version 6 and 8 capabilities of handeling complex logic and can it be used extensively for transformation or it is advisable to use it just as a transfer layer with minimal business logic.
Thanks... |

An application server such as WAS may be better suited for the processing of complex business logic.
Whether or not that is the case for you is something that you must find out for yourself. A POC is what will give you this information.
Have fun

An alternative answer is that complex business rules are best managed by a rules engine, and WMB can interface to rules engines ( in fact, IIB v9 embeds a rules engine in every execution group/server ).
Can you give some details of the complex logic that you are thinking of?

Hi..
The business logic involves traversing through big size messages... 2-3 MB Edifact messages and inserting them in database.
Also there are few interface which involve big lookup tables and we need to traverse through them.
In general, I wanted to know about the MB capability to transform the messages.
Is MB more of tranfer middleware then a transformation middleware?? |

MB or IIB as it is now called is a high performance messaging engine that can do the job you require of it perfectly well.
Why do you have these doubts? you are using a fantastic tool that works really well.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

This is an unusual question. WMB is an extremely capable and high-performance middleware engine, and all of the documentation makes that clear. What made you ask the question?

2-3Mb is not large by WMB standards. If you are concerned that the message sizes could get even larger ( more than 10Mb ) then there are well-known techniques to minimize memory usage while processing very large messages.

You mean, you need to perform lookups in large lookup tables? That's a standard WMB problem with a range of well-known solutions.
It might be worth considering going straight to IIB v9 rather than WMB v8. And note that ESQL is not the only transformation language avaiable in WMB/IIB.
