LogRecord Class
Assembly: System.EnterpriseServices (in system.enterpriseservices.dll)
Unstructured log records are delivered as a COM+ CrmLogRecordRead structure. In addition to the user data (a single BLOB), this contains additional fields that are useful for debugging or fault finding. The Flags field is a bit field that provides further information about whether this record was forgotten at some point, and when it was written. The Sequence field provides the sequence number of the log record. In most cases, sequence numbers are sequential but are not necessarily contiguous due to internal log records that are not delivered to the Compensating Resource Manager (CRM) Compensator.
The following code example demonstrates the use of this class.
Public Overrides Function AbortRecord(ByVal log As LogRecord) As Boolean ' Check the validity of the record. If log Is Nothing Then Return True End If Dim record As [Object]() = log.Record If record Is Nothing Then Return True End If If record.Length <> 2 Then Return True End If ' Extract old account data from the record. Dim filename As String = CStr(record(0)) Dim balance As Integer = Fix(record(1)) ' Restore the old state of the account. AccountManager.WriteAccountBalance(filename, balance) Return False End Function 'AbortRecord
public boolean AbortRecord(LogRecord log)
{
// Check the validity of the record.
if (log == null) {
return true;
}
Object record[] = new Object[] { log.get_Record() };
if (record == null) {
return true;
}
if (record.get_Length() != 2) {
return true;
}
// Extract old account data from the record.
String fileName = (String)(record.get_Item(0));
int balance = System.Convert.ToInt32(record[1]);
// Restore the old state of the account.
AccountManager.WriteAccountBalance(fileName, balance);
return false;
} //AbortRecord
