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.
