Hi ,
I have a requirement in IIB where I need to read a file which contains multiple records(say an xml) delimited by a character say @@@.So I need to extract each record and put to a queue.
This has to happen within a transaction.Say If I have 100 records in the file,I have to put it as 100 different messages in the queue.If any failure occurs then all the messages have to be rolled back and not put into the queue. Please suggest me how to do it. |

Have you looked at the FileInput Node and its options for handling records?
Have you looked at the FileInput Node and its options for transactionality?
Have you looked at the MQOutput Node and its options for how it handles transactionality?
Have you looked at the MQ documentation on the Max Number of un-comitted messages?
Then think about how you would tie all that together and you will be getting close to your solution.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

I'm afraid you can't do that with FileInput Node:
| Quote: |
| One or more messages can be read from a single file, and each message is propagated as a separate flow transaction. The part of a file that generates one message flow transaction is called a record. A file can be a single record, or a series of records. Properties on the node specify how the FileInput node determines the records in a file. |

You can process the whole file as one record, and then generate multiple MQ messages using propagate inside a ESQL loop.
Just be aware of memory size limitations if doing this.

| Have you considered building a model that matches the message you actually need to read from the file? I.e. a model that includes up to 100 repeats? |
