oracle 11g 創建 dblink 連接 postgreSQL一點補充

 

最新需要通過Oracle連接到PosgreSQL,碰到了一點問題，參考文章很詳細，但是listener.ora配置有點小問題，會導致配置出錯。

正確的配置例子是紅色部分:

驗證listener的結果如下:

同時也把配置和結果以文本的方式粘貼處理，供參考:

listener.ora

# This is a sample listener.ora that contains the NET8 parameters that are
# needed to connect to an HS Agent

LISTENER =
 (ADDRESS_LIST=
      (ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1521))
 )

SID_LIST_LISTENER=
  (SID_LIST=
      (SID_DESC=
         (SID_NAME=PG_LINK)
         (ORACLE_HOME=O:\app\Henry\product\11.2.0\dbhome_1)
         (PROGRAM=dg4odbc)
      )
      (SID_DESC=
         (SID_NAME=ORCL)
         (ORACLE_HOME=O:\app\Henry\product\11.2.0\dbhome_1)
         (GLOBAL_DBNAME=ORCL)
      )
  )

#CONNECT_TIMEOUT_LISTENER = 0 

tnsnames.ora

# This is a sample tnsnames.ora that contains the NET8 parameters that are
# needed to connect to an HS Agent

PG_LINK  =
  (DESCRIPTION=
    (ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1521))
    (CONNECT_DATA=(SID=PG_LINK))
    (HS=OK)
  ) 

initPG_LINK.ora

# This is a sample agent init file that contains the HS parameters that are
# needed for the Database Gateway for ODBC

#
# HS init parameters
#
HS_FDS_CONNECT_INFO = PG_LINK
HS_FDS_TRACE_LEVEL = DEBUG


#
# Environment variables required for the non-Oracle system
#
#set <envvar>=<value>
