Hi,

In the organisation that I work for we are in the process of upgrading our systems. The new system needs the message in xml format
the requester sends the request in a legency properitory format.

We contacted IBM and they say that DP can convert the message from any format ( I have the specification of the message) to XML
( I have the required schema).


Now what is the speed at what the system will be processed.
I am new to DP , Can I have any link/ docs to understand DP.

If we use DP should all the interfaces be MQ enabled?

Regards

Only some models of DP can transform from legacy formats to XML.

Only some models of DP can talk to MQ.

At least, last I knew.

Not sure what you are looking for, but you can start here:

DP is not a direct transformation tool. It integrates with contivo and WTX to get the job done. Actually, lemme rephrase ... DP has a transformation engine and u can write the code to do the transformation. WTX and contivo would generate the code for u.

generate the transformation code from WTX or contivo and import it onto DP.

In the transform or binary transform action in the DP policy, point to the file ( xsl with ffd in case of contivo; xml in case of WTX ). DP would then jus execute the code and get the transformation done.

cheerz!!!

Hi,

We write xslt transformations using XPATH which is very efficient and performant. However we are looking at trialing WTX to see how it fits in with our requirements

The XI150 appliance handles multiple protocols using a Multi Protocol Gateway. This is useful if your clients are http, MQJMS, to name a few and you backends have an MQ interface.

If your clients are sending SOAP over http then you could use a WebService proxy object to acheive the above. A Route set action node can be added to the policy which allows you to specify the MQ details.

We have the DP to get the message in text format and convert to XML format.

Now there is a system1 which puts the messages in text format to MQ and DP connects to this MQ as a client and reads the message and transforms it to XML and another system2 gets the message and process it according to the business rules gives the messages which DP gives to system1.

In this scenario DP connects to QM of system1 and system2 as an Mq client and does not have a QM of its own.

There is another set up by which there is a middleware set up, which consists of MQ server and DP which manages the messages from system1 and system2.


Any comments of the above set up are welcome

Regards

DataPower only allows any connection from MQ with certain models.

There is no DataPower model that can act as an MQ Server, it only acts as an MQ Client.

Thanks for the replies.

We are in the process of converting the messages from the legacy format to xml format using DP XI50

We are using a MQ server ( a seperate box) and DP connects as an MQ client and gets the messages.

The below may be a basic question but I need to know how DP handles messages

Consider this scenario , the message being put by DP ( MQ client ) to MQ server (a seperate box). If there is a network failure in between, will the message be lost or DP does not commit the message until a successful response is got so the message is intact.

You can have DP configured to two queue managers, one primary and the other secondary. It picks up secondary on the failure of primary.
