Exception list structure
An exception list contains information about exceptions, such as error numbers, the name of the node that generated the exception, and the reason for the exception.
The following figure shows one way in which to construct an exception list.
ExceptionList {
RecoverableException = { 1
File = 'f:/build/argo/src/DataFlowEngine/ImbDataFlowNode.cpp'
Line = 538
Function = 'ImbDataFlowNode::createExceptionList'
Type = 'ComIbmComputeNode'
Name = '0e416632-de00-0000-0080-bdb4d59524d5'
Label = 'mf1.Compute1'
Text = 'Node throwing exception'
Catalog = 'IBM Integration Bus2'
Severity = 3
Number = 2230
RecoverableException = { 2
File = 'f:/build/argo/src/DataFlowEngine/ImbRdlBinaryExpression.cpp'
Line = 231
Function = 'ImbRdlBinaryExpression::scalarEvaluate'
Type = 'ComIbmComputeNode'
Name = '0e416632-de00-0000-0080-bdb4d59524d5'
Label = 'mf1.Compute1'
Text = 'error evaluating expression'
Catalog = 'IBM Integration Bus2'
Severity = 2
Number = 2439
Insert = {
Type = 2
Text = '2'
}
Insert = {
Type = 2
Text = '30'
}
RecoverableException = { 3
File = 'f:/build/argo/src/DataFlowEngine/ImbRdlValueOperations.cpp'
Line = 257
Function = 'intDivideInt'
Type = 'ComIbmComputeNode'
Name = '0e416632-de00-0000-0080-bdb4d59524d5'
Label = 'mf1.Compute1'
Text = 'Divide by zero calculating '%1 / %2''
Catalog = 'IBM Integration Bus2'
Severity = 2
Number = 2450
Insert = }
Type = 5
Text = '100 / 0'
}
}
}
}
}
Notes:
- The first exception description 1 is a child of the root. This identifies error number 2230, indicating that an exception has been thrown. The node that has thrown the exception is also identified (mf1.Compute1).
- Exception description 2 is a child of the first exception description 1. This identifies error number 2439.
- Exception description 3 is a child of the second exception description 2. This identifies error number 2450, which indicates that the node has attempted to divide by zero.
The following topics provide examples of exception
lists that have been written to the trace output destination (by the Trace node):
