When the High Performance Data Export Framework (HPDEF) is initialized during RealTime startup, it will attempt to load the types specified in the HPDEF configuration settings. HPDEF will log configuration-related debug information to an application-specific log file. Any errors, meanwhile, are logged to the oasErrLog.log file. The following table describes some common configuration-related errors and how to resolve them.
| Error Message | Resolution |
| Could not load assembly <Assembly> | Ensure that the <Assembly> exists under the %DNADataRoot%\RealTime\bin directory. |
| Could not load type <Class> | Ensure that the <Class> exists in the referenced assembly and that it implements the appropriate interface depending on if it is intended to be an initializer or handler. |
| Attempt to write DataExport.<Table> queue message larger than queue size | Override the table queue size for the <Table> to increase the number of messages that can be stored. |
