Connecting from oracle on windows 2008 64 bit to sql server.

Question

Hi,
Oracle Server name: oraxyz
Database: 11.2.0.4 on windows 64 Bit.
Database home: d:\app\product\11.2.0\db_1
SQL server: sqlabc
I have a oracle database 11.2.0.4 on widows 2008 64 Bit on host oraxyz. I have to connect to SQL server sqlabc from this oracle database.
So I installed gateway for windows on oraxyz server in location d:\app\product\11.2.0\gateway.
My initdg4msql in Gaeway oracle home dg4msql\admin looks like this.
# This is a customized agent init file that contains the HS parameters
# that are needed for the Database Gateway for Microsoft SQL Server
# HS init parameters
HS_FDS_CONNECT_INFO=[sqlabc]:1433//prodsql
HS_FDS_TRACE_LEVEL=OFF
HS_FDS_RECOVERY_ACCOUNT=RECOVER
HS_FDS_RECOVERY_PWD=RECOVER
Then I created a listener in gateway oracle home as follows.
DG4MSQL =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = oraxyz)(PORT = 1524))
SID_LIST_DG4MSQL =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = dg4msql)
      (ORACLE_HOME = D:\app\product\11.2.0\Gateway)
      (PROGRAM = dg4msql)
Then in Oracle db home I created a tns alias as follows.
dg4msql =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = oraxyz)(PORT = 1524))
    (CONNECT_DATA =
      (SID = dg4msql)
      (HS = OK)
Then created a database link as follows
SQL>CREATE PUBLIC DATABASE LINK tosql connect to abc identified by 123 using 'DG4MSQL';
SQL> DESC sqlservertable@tosql gives me error
ERROR:
ORA-28546: connection initialization failed, probable Net8 admin error
ORA-02063: preceding line from tosql
Could any one please help.
Do I have to create any ODBC connection for that?
BR

Not part of your problem (yet) but I always get heartburn when I see someone naming their listener as if it has a relationship to something when it doesn't.  There really is no point to naming a listener as anything but its default name of LISTENER.
So, in your listener.ora, instead of
DG4MSQL =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = oraxyz)(PORT = 1524))
SID_LIST_DG4MSQL =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = dg4msql)
      (ORACLE_HOME = D:\app\product\11.2.0\Gateway)
      (PROGRAM = dg4msql)
Just use
LISTENER=
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = oraxyz)(PORT = 1524))
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = dg4msql)
      (ORACLE_HOME = D:\app\product\11.2.0\Gateway)
      (PROGRAM = dg4msql)
