Hi all,
Can we covert a BLOB message into MRM message in a compute node,if we don't no the message type.I have 'n' no.,of messages in a message set,so i can't give the message name.It will be a great help,if any one can reply back on this.
Thank's

Kiran,
ASAIK, no you can't as the parser needs to know which message to parse it against.
Is there anything in the BLOB you can check for (in hex) to determine which of the messages it is. Then you can set the properties to allow it to be parsed.
Cheers,

Hi,
Can we convert a BLOB message to MRM type in COMPUTE node,if we know the Message type.
Thanks

Hi,
you can't do it within a single compute node
even if you know the message type, since there
is no ESQL command to force the parser to reparse
the message buffer.
In your situation what one typically does, is use
an *external* loop parse the message piecemeal.
E.g.
- save message as blob in DestinationList
- filter(more messages ?)
- compute(extract next into blob,set MessageDomain to BLOB,set MRM message type)
- resetcontentdescriptor(to MRM)
- do your stuff with that part of the message
- compute(increase message counter)
- jump back to filter node
See the recent topic on 'BIP2121E and BIP2106E' for implications
when you use these external loops.

With WMQI 2.1, you can actually do a partial parse in a Compute node, using reference variables and the new CREATE statement:
CREATE NEXTSIBLING OF myRef PARSE(
SUBSTRING(InputBody."BLOB" FROM 101),
MQENC_INTEGER_REVERSED, myCCSID, myMsgSetID, myMsgID, myMsgFormatID);

Hi,
if you are already using 2.1 Miriams solution is as short as it gets.
If you still have to use 2.0.2 let me know your email address
in a private message and I'll mail you an example.
