Consider the following scenario:

  • You have a computer that is running Microsoft BizTalk Server 2006 R2 or Microsoft BizTalk Server 2009.

  • You use Microsoft BizTalk Adapter 3.0 for Oracle Database from Microsoft BizTalk Adapter Pack 2.0 to connect to an Oracle server.

  • A table in the Oracle server has a column that contains a LONG RAW data type.

  • The Oracle database adapter tries to return the data from the Oracle server.

In this scenario, the Oracle database adapter returns an array of "system.byte" elements instead of the data.


This issue occurs because of an error in the Oracle database adapter.

More Information

Long data types are deprecated by Oracle in favor of LOB data types. Therefore, the LongDataTypeColumnSize binding property is deprecated in the BizTalk Adapter Pack 2.0 version of the Oracle Database adapter.

If you use the LongDatatypeColumnSize binding property, set -1 as the value to avoid avoids memory issues.
