Hi...

I am trying to add the MQIIH using Compute Node. I am able to do that using the SET OutputRoot.MQIIH. ....

But when a message is sent to MQ-IMS Bridge... it expects LL ZZ Transcode and then the actual data.

The LL field contains the size of the message plus 2 bytes for the LL plus 2 bytes for the ZZ ZZ contains zeros.

I can do this using a Java Program or a C++ program. But adding this after the MQIIH and before the data is painful using Compute Node.

Has anyone done this before..??

For MQ/IMS-bridge messages our CWF construct is comprised of two elements:

The LL portion of the LLZZ is defined as a xsd:short with a physical type of integer. Length is 2 bytes.
The message PAYLOAD is defined as a xsd:string with a Physical Type of Length Encoded String 2.
An element defined as Length Encoded String 2 requires the first 2 bytes be the length of the payload, in essence the ZZ portion of the LLZZ.

Quote:

Length Encoded String 2. The element's first two bytes contain the length of the string following the 2 length bytes in length units. The maximum length of a Length Encoded String 2 element is 65535 length units. The two length bytes are in the format of the WebSphere MQ queue manager Encoding.
