DG4MSQL version 11.2.0.3.0, any query results in 'got native error 1007'

Question

I installed Oracle Gateway for MSSQL version 11.2.0.3.0 to a separate Oracle Home (platform is IBM AIX 6.1 64-bit). After setting up listener, init.ora file etc., I created database link and tried few queries (database version 11.2.0.2.0 with patches 12827726, 12827731 applied). All queries result in error message:
SQL> select count(*) from s4user@imosprodnew;

Could this be some sort of incompatibility between DG4MSQL version 11.2.0.3.0 and RDBMS version 11.2.0.2.0?
I did not find anything relevant by searching, really (apart from one thread suggesting that this could be caused by misconfigured Linux OS, but my platform is AIX)

Answer 1

I created test table and inserted data (using FreeTDS tsql tool):
locale is "en_US.UTF-8"
locale charset is "UTF-8"
1> use imosprod
2> go
1> create table TEST_MSSQL (PKEY integer, DATA varchar(20))
2> go
1> insert into TEST_MSSQL values (1000,'Data for key 1000')
2> go
1> insert into TEST_MSSQL values (2000,'Data for key 2000')
2> go
1> select * from TEST_MSSQL
2> go
PKEY    DATA
1000    Data for key 1000
2000    Data for key 2000
(2 rows affected)
Then, I queried test table with:
1) DG4ODBC 11.2.0.2 + IBM-branded DataDirect ODBC driver,
2) DG4MSQL 11.2.0.2 and
3) DG4MSQL 11.2.0.3
Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production
With the Partitioning and Automatic Storage Management options

Seems to be a change in internal logic of DG4MSQL in version 11.2.0.3 to me.
