Oracle通过dblink访问DM7相关配置的方法

Oracle连接DM7的相关配置，可以通过odbc接口实现。具体方法如下：

1.配置odbc

在odbc 64位（其中案例Oracle和DM都是64位）系统DSN中，配置dmlink的数据源，测试通过即可。

2.配置HS

在%ORACLE_HOME%/hs/admin/路径下添加文件initDMSERVER.ora
内容：

HS_FDS_CONNECT_INFO = dmlink
HS_FDS_TRACE_LEVEL = debug

3.配置Oracle监听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 = DMSERVER)
      (ORACLE_HOME = D:\app\product\11.2.0\dbhome_1)
      (PROGRAM = dg4odbc)
    )
  )
LISTENER =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
  )
ADR_BASE_LISTENER = d:\app

4.配置Oracle的tnsnames.ora

添加：

DM =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = DMSERVER)
    )
    (HS=OK)
  )

5.登录oracle测试，

create database link dmlink connect to "SYSDBA" identified by "SYSDBA" using 'DM'; 

测试即可，亦或使用select * from test_1@DMLINK;测试是否能查询出结果。
