further to mqmatt Post,
I need one suggestion, I am trying to have two paths one each for the empty message and non empty message using filter node check,
In case non-empty message i will use RCD to BLOB.
For the non empty is the follwing code ok in compute node to get the empty message in BLOB domain? (along with MQRFH2 Header).
SET OutputRoot.Properties = InputRoot.Properties;
SET OutputRoot.Properties.MessageSet = '';
SET OutputRoot.Properties.MessageType = '';
SET OutputRoot.Properties.MessageFormat = '';
SET OutputRoot.MQMD = InputRoot.MQMD;
SET OutputRoot.MQRFH2 = InputRoot.MQRFH2;
DECLARE parseOptions INTEGER BITOR(FolderBitStream, ValidateContent, ValidateValue, ValidateLocalError);
DECLARE mraMsg BLOB;
SET mraMsg = CAST('' AS BLOB CCSID InputRoot.MQMD.CodedCharSetId ENCODING InputRoot.MQMD.Encoding);
DECLARE creationPtr REFERENCE TO OutputRoot;
CREATE LASTCHILD OF creationPtr DOMAIN('BLOB') PARSE(mraMsg, InputRoot.MQMD.Encoding, InputRoot.MQMD.CodedCharSetId);
RETURN TRUE;
Please suugest alternate way to keep MQRFH2 header intact in case of null Message body!!
Regards |

How about just a few more lines
create lastchild of OutputRoot domain 'BLOB' name 'BLOB';
create lastchild of OutputRoot.BLOB name 'BLOB';
SET OutputRoot.BLOB.BLOB VALUE = NULL;
No costly casting or parsing...
Enjoy

I think this statement causes to delete the message body node which we don't want. We want to keep this to preserve the MQRFH2 header for the future reference. else the MQRFH2 might be referenced as a body. Am I right fjb_saper?

If you forget the VALUE key word it will remove the node. That is why it is essential no to omit the word VALUE when assigning a null value.
