Create Table Trigger to replicate data from MSSQL2K5 to Oracle 11G on Linux

Question

I am trying to create a trigger on my MSSQL 2k5 server so that when a record is inserted, a replicated record is created in a table on an Oracle 11g database on a Linux server (Oracle Linux 6).
Creating the trigger is easy, but when I test it I am getting an error stating the following:
.NetSqlClient Data Provider The operation could not be performed because OLE DB Provider 'OraOLEDB.Oracle' for linked server "<myserver>" was unable to begin the distributed transaction.
OLEDB Provider "OraOLEDB.Oracle" for linked server "<myserver>" returned: "New transaction cannot enlist in the specified transaction coordinator"
Here is the trigger (MSSQL):
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE PROCEDURE insert_aban8_state
    @an8 int,
    @st nvarchar(3)
AS
BEGIN
    SET NOCOUNT ON;
    declare @c numeric
    select @c = count(*) from [e9db]..[CRPDTA].[ABAN8_STATE$] where alan8=@an8 and aladds=@st
    if(@c =0)
     begin
        insert into [e9db]..[CRPDTA].[ABAN8_STATE$]
        values(@an8, @st)
     end
    END
GO
After reviewing the MS Transaction Coordinator, I am now totally confused. I checked the services and have the MS DTC enabled and running, but am not sure what to do on the Linux side.
Does the Oracle Services for Microsoft Transaction Server (OraMTS) work on Linux? I could only find references for this for Oracle 11g on Windows.
What do I need to do to enable this replication via mssql table trigger to Oracle11g on Linux?

While I would agree in part, it appears from the message that the trigger is requiring the Transaction Service to be enabled on both the host and target. The point of this post is to determine what, if anything, I need to do on my Oracle DB to allow the trigger to complete successfully.
There are many posts found with Google concerning the OraMTS service on the Oracle system, but they all appear to be for Windows based systems. My question is, is this service part of the Linux based Oracle DB and if so, how do I initialize it?
If I am mistaken and this is truly an issue with the MSSQL server, I will replicate the post in those forums. I am just looking for direction and help.
1) I have NEVER heard that Oracle has, knows about, or supports any "Transaction Service".
2) Consider what I previously posted regarding the flavor of client source.
If your assertion about this mythical service were correct, then the Oracle DB would have to be able to "know" that this client connection was originated by SQL Server.
I don't understand how or why Oracle should behave differently depending upon whether INSERT is done inside or outside a MS SQL Server trigger.
Please explain & elaborate why Oracle should behave different depending upon the source of any INSERT statement.
3) From Oracle DB standpoint an INSERT is an INSERT; regardless of the client.
