I am using oracle 11gR1 on windows 2003.
This is my initaccessdb.ora(Path HS/ADMIN)
HS_FDS_CONNECT_INFO = ACCESSDB
HS_FDS_TRACE_LEVEL = OFF
Listner File
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = APPSERVER)(PORT = 1521))
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(SID_NAME=PLSExtProc)
(ORACLE_HOME=E:\app\Administrator\product\11.1.0\db_1)
(PROGRAM=extproc)
     (SID_DESC =
     (SID_NAME = accessdb)
(ORACLE_HOME = E:\app\Administrator\product\11.1.0\db_1)
(PROGRAM = ACCESSDB)
     (ENVS=LD_LIBRARY_PATH=D:\)      
TNSNAME.ORA
ORCL =
(DESCRIPTION =
     (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.0.14)(PORT = 1521))
     (CONNECT_DATA =
          (SERVER = DEDICATED)
          (SERVICE_NAME= ORCL)
ACCESSDB =
(DESCRIPTION=
     (ADDRESS =(PROTOCOL = TCP)(HOST=172.16.0.14)(PORT=1521))
          (CONNECT_DATA =
          (SERVICE_NAME=ACCESSDB))
               (HS = OK)
I successfully completed all steps as mentioned in your sending links documents but when i test my dblink query it gives the error message
SQL> conn sys as sysdba
Enter password:
Connected.
SQL> conn ahmed
Enter password:
Connected.
SQL> drop database link test;
Database link dropped.
SQL> create database link test using 'ACCESSDB';
Database link created.
SQL> SELECT * FROM EMPLOYEE@TEST;
SELECT * FROM EMPLOYEE@TEST
ERROR at line 1:
ORA-28545: error diagnosed by Net8 when connecting to an agent
Unable to retrieve text of NETWORK/NCR message 65535
ORA-02063: preceding 2 lines from TEST
Note: Please tell me that should i install ODBC driver ("Microsoft Access Driver *.mdb).If this should be installed then i have done correctly.
Thanks
