创建DBLINK Oracle到SQL Server的错误

编程问答 2022-06-12

问题描述

我正在创建DBLINK Oracle（11gR2）（Windows Server 2008）到SQL Server（Windows 10）。

我已经安装了Oracle Gateway。

我在ODBC数据源管理器中创建了一种数据字体，连接正常。他叫Integra。

我更改了文件listener.ora，tnsnames.ora，sqlnet.ora和initIntegra.ora。

遵循我的设置：

服务器Oracle无IP：192.168.1.22

服务器SQLServer否IP：192.168.1.18

Listener.ora 

SID_LIST_LISTENER =
  (SID_LIST =
(SID_DESC =
  (SID_NAME = CLRExtProc)
  (ORACLE_HOME = D:\app\product\11.2.0\dbhome_1)
  (PROGRAM = extproc)
  (ENVS = "EXTPROC_DLLS=ONLY:D:\app\product\11.2.0\dbhome_1\bin\oraclr11.dll")
)
(SID_DESC =
  (SID_NAME = CLRExtProc)
  (ORACLE_HOME = D:\app\product\11.2.0\dbhome_1)
  (PROGRAM = extproc)
  (ENVS = "EXTPROC_DLLS=ONLY:D:\app\product\11.2.0\dbhome_1\bin\oraclr11.dll")
)
(SID_DESC =
  (SID_NAME = )
  (ORACLE_HOME = D:\app\product\11.2.0\dbhome_1)
  (PROGRAM = dg4odbc)
)
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = Serverlab3)(PORT = 1521))
    )
  )
ADR_BASE_LISTENER = D:\app

tnsnames.ora 

Integra =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = Integra)
    )
  )

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

sqlnet.ora 

# This file is actually generated by netca. But if customers choose to 
# install "Software Only",this file wont exist and without the native 
# authentication,they will not be able to connect to the database on NT.
SQLNET.AUTHENTICATION_SERVICES = (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES,EZCONNECT)

创建DBLINK 

CREATE DATABASE LINK INTEGRA CONNECT TO "sa" IDENTIFIED BY "senha" USING 'Integra';

select * from tabela@INTEGRA;

SQL错误[28546] [99999]：ORA-28546：连接初始化失败，可能是Net8管理员错误。 ORA-02063：INTEGRA的前一行 *

注意：我在ODBC管理器中的数据源名称为Integra。并且ODBC Windows管理员进行的连接测试非常有效。

一个问题： 在TNSNAMES中，主机必须是LOCALHOST和端口1521吗？

谢谢。
