The MQGet node
generates message trees based on the input message assembly that
it receives, and the options that you have set on the node properties.
The message trees, shown in the following table, are generated
according to the rules described in How the MQGet node implements IBM MQ MQGet API calls.
| With a message assembly like this: |
The message that the MQGet node returns is: |
- InputRoot
- MQMD
- {input message MQMD}
- MQRFH2
- {input message MQRFH2}
- XMLNS
- {input message body}
- InputLocalEnvironment
- MQ
- GET
- MQGMO
- MatchOptions = MQMO_MATCH_CORREL_ID
- MQMD (with no children)
- Variables
- MQMD
- {input MQMD} (with CorrelID = {correct Correlation ID as binary})
|
- ResultRoot
- MQMD
- {result message MQMD}
- MQRFH2
- {result message MQRFH2}
- XML
- {result message body}
|
| With the following node property settings: |
The resulting output message assembly is: |
- Input MQMD Location
- InputLocalEnvironment.Variables.MQMD
- Copy Message
- Copy Entire Message
- Copy Local Environment
- Copy Entire LocalEnvironment
- Generate Mode
- Message and LocalEnvironment
- Output Data Location
- InputLocalEnvironment.Variables.ReturnedMessage
|
- OutputRoot
- MQMD
- {input message MQMD}
- MQRFH2
- {input message MQRFH2}
- XMLNS
- {input message body}
- OutputLocalEnvironment
- MQ
- GET
- MQGMO
- {MQGMO used for MQGET}
- MQMD
- {MQMD used for MQGET}
- CC = 0
- RC = 0
- Variables
- MQMD
- {input MQMD} (with CorrelID = {correct Correlation ID as binary})
- ReturnedMessage
- MQMD
- {result message MQMD}
- MQRFH2
- {result message MQRFH2}
- XML
- {result message body}
|
- Result Data Location
- ResultRoot.XML
|
- OutputRoot
- MQMD
- {input message MQMD}
- MQRFH2
- {input message MQRFH2}
- XMLNS
- {input message body}
- OutputLocalEnvironment
- MQ
- GET
- MQGMO
- {MQGMO used for MQGET}
- MQMD
- {MQMD used for MQGET}
- CC = 0
- RC = 0
- Variables
- MQMD
- {input MQMD} (with CorrelID = {correct Correlation ID as binary})
- ReturnedMessage (with any attributes and value from ResultRoot.XML)
- {result message body}
This tree is effectively the result of doing an
assignment from ${resultDataLocation} to ${outputDataLocation}.
The value of the source element is copied, as are all children including
attributes.
|
- Copy Local Environment
- None
|
- OutputRoot
- MQMD
- {input message MQMD}
- MQRFH2
- {input message MQRFH2}
- XMLNS
- {input message body}
- OutputLocalEnvironment
- MQ
- GET
- MQGMO
- {MQGMO used for MQGET}
- MQMD
- {MQMD used for MQGET}
- CC = 0
- RC = 0
- Variables
- ReturnedMessage (with any attributes and value from ResultRoot.XML)
- {result message body}
This tree has the MQMD that is used for the MQGET call
in the OutputLocalEnvironment, because the input MQ parameters location
had an MQMD element under it. Even though the input tree is not copied,
the presence of the MQMD element causes the MQMD that is used for
the MQGET call to be placed in the output tree.
|
- Output Data Location
- <blank>
- Copy Local Environment
- Copy Entire Local Environment
|
- OutputRoot
- MQMD
- {result message MQMD}
- MQRFH2
- {result message MQRFH2}
- XMLNS
- {result message body}
- OutputLocalEnvironment
- MQ
- GET
- MQGMO
- {MQGMO used for MQGET}
- MQMD
- {MQMD used for MQGET}
- CC = 0
- RC = 0
- Variables
- MQMD
- {input MQMD} (with CorrelID = {correct Correlation ID as binary})
The value that you set for the Copy Message property makes no
difference to the eventual output tree in this case.
