8/24/2006 Why messages are immutable inside Biztalk?

Posted at: 8/24/2006 at 7:12 AM by saravana
Most of us know that messages received inside biztalk are immutable, meaning they cannot be modified. If we need to modify the message say for example, if you want to change the price of the product inside the message, then a new message needs to be constructed (Inside orchestration you use Construct, Transform shape etc, inside pipeline you create a temporary stream). So, whats the reason for this immutable message behaviour. Reasons: 1. A received message might have multiple subscribers (or... [More]

8/23/2006 Handling incoming data streams in pipeline components in BizTalk Server 2004/2006

Posted at: 8/23/2006 at 5:31 PM by saravana
When you write custom disassembler code for pipeline components, you must make sure that you do not close the incoming data stream in the custom disassembler code. The incoming stream from the input message is a shared resource. The incoming stream is also used by the message body tracking component in the BizTalk Server message engine. If you either implicitly or explicitly close the incoming stream, tracking data may be lost. Therefore, you cannot examine the data in the Health and Activity... [More]

8/23/2006 Delete Byte Order Mark from outgoing messages in Biztalk 2004/2006

Posted at: 8/23/2006 at 5:00 PM by saravana
A byte order mark is appended to a message when the assembler component or the disassembler component is used to process a message in BizTalk Server. If you use a PassThruReceive pipeline or a PassThruTransmit pipeline, a byte order mark is not appended to a message. In UTF-16 encoding, a byte order mark is the FE FF byte sequence or the FF FE byte sequence at the start of the encoded string. The FE FF byte sequence indicates that the encoded characters that follow use the big-endian byte ord... [More]
