ORACLE ile SQL SERVER ARASINDA DBLINK OLUŞTURMAK

• İlk olarak SQL SERVER’a odbc ile bağlantı sağlanır




• İkinci adım olarak heterojen servis için pfile yaratılır.

Örnek dosya $ORACLE_HOME/hs/admin/inithsodbc.ora

# This is a sample agent init file that contains the HS parameters that are
# needed for an ODBC Agent.
# HS init parameters
#
HS_FDS_CONNECT_INFO =
HS_FDS_TRACE_LEVEL =
#
# Environment variables required for the non-Oracle system
#
#set =

C:\oracle\product\10.2.0\db_1\hs\admin\initSQLSERVER.ora

HS_FDS_CONNECT_INFO=SQLSERVER
HS_FDS_TRACE_LEVEL=OFF

Dosyası yaratıldı.

• Daha sonra Listener.ora dosyası yaratılır.

Örnek dosya $ORACLE_HOME/hs/admin/listener.ora
Sql server için Listener yaratlır.LISTENERSQLSERVER

Listener.ora

LISTENERSQLSERVER =
(ADDRESS_LIST=
(ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1522))
)
SID_LIST_LISTENERSQLSERVER=
(SID_LIST=
(SID_DESC=
(SID_NAME=SQLSERVER)
(ORACLE_HOME=C:\oracle\product\10.2.0\db_1)
(PROGRAM=hsodbc)
)
)

Bu bilgiler $ORACLE_HOME/network/admin altındaki listener.ora dosyası içine kopyalanır.

• Tnsnames.ora dosyası düzenlenir,
$ORACLE_HOME/hs/admin/tnsnames.ora

SQLSERVER =
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1522))
(CONNECT_DATA=(SID=SQLSERVER))
(HS=OK)
)

Bu bilgiler $ORACLE_HOME/network/admin/tnsnames.ora dosyasınada kaydedilir.

• Daha sonra listener’ı başlatıyoruz.

C:\>lsnrctl start listenersqlserver

• En son adım olarak ta dblink yaratılır.

create database link sql connect to username identified by password using 'SQLSERVER';
