ADONetAppender and Oracle 8i ORA-12704: character set mismatch

["Esterbrooks, Brette" <BG...@landolakes.com>]

Hello All,
I am running into an issue with the ADONetAppender and writing to an
oracle 8i database. When the query attempts to run I get the following
error.
System.Data.OracleClient.OracleException: ORA-12704: character set
mismatch This is proving to be a harder problem to solve then I though.
Here is my config or at least the appropriate sections. It appears it is
having some trouble with the conversion to a varchar2 in the oracle
database. Anyone seen this? Also if I hard code the values as such it
works fine. So something must be happening on the Prepared statement
bind that is causing probs.

 <commandText value=3D"INSERT INTO Log (Log_Level,Logger,Message) VALUES
('asdfasfasdf', 'asdfasfasdf', 'asdfasfasdf')" />

Table def.
CREATE TABLE LOG
(
THREAD VARCHAR2(255),
LOG_LEVEL VARCHAR2(255),
LOGGER VARCHAR2(255),
MESSAGE VARCHAR2(4000)
)
