oracle和sqlserver互訪(1)

要求:從Oracle中能取SqlServer的資料
環境:
OracleDb: Linux + Oracle9i Enterprise Edition Release 9.0.1.1.1 - Production IP:192.168.1.52(TOPPROD)
MSQLDB: Windows2000 + SqlServer2000 IP:192.168.1.50(ERPSQL),測試使用者:sa/pass 測試資料表:EK.ACPTA
網 關: WindowsXp + Oracle9i Enterprise Edition Release 9.0.1.1.1 - Production IP:192.168.1.221(S0504027),因為暫在測試階段,所以閘道器裝在我用的機器,閘道器可以裝在MSQLDB上

1.透過ODBC通用方式聯接

程式碼:

// A. 安裝HS部件

//     預設情況下HS部件是安裝的,查詢檢視 SYS.HS_BASE_CAPS 可得出有沒有安裝此部件!

// B. 配置ODBC

//     在"系統DNS"中配置"ODBC FOR SQLSERVER",例如:[ERPSQL]

// C. 配置TNSNAMES.ORA,路徑:ORACLE_HOMENETWORKADMIN,這一步應該在ORACLEDB(192.168.1.52)上配置!Lnk2sql =                  # tnsName

  (DESCRIPTION = 

    (ADDRESS_LIST = 

        (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.221)(PORT = 1521))     # 閘道器IP

     )

    (CONNECT_DATA = 

        (SID = hs4sql)    #SID,要和監聽器裡的SID一致!

    ) 

    (HS=OK)// D. 配置listener.ora,路徑:ORACLE_HOMENETWORKADMINLISTENER =

  (DESCRIPTION_LIST =

    (DESCRIPTION =

      (ADDRESS_LIST =

        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))

      )

      (ADDRESS_LIST =

        (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.221)(PORT = 1521))

      )

    )

  )

SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =         # 這一段為加入的

        (SID_NAME = hs4sql)

        (ORACLE_HOME = D:oracleora9i)

        (PROGRAM = hsodbc)   # 要使用的HS服務程式.

    ) 

  )// E. 重啟監聽器服務

// F. 編輯ORACLE_HOMEHSADMIN內init.ora，這裡是iniths4sql.ora,因為上面的SID=hs4sqlHS_FDS_CONNECT_INFO = ERPSQL     # B中設定的ODBC名稱HS_FDS_TRACE_LEVEL = 0// G. 建立DB LINK,以及測試SQL>  create database link ora2sql connect to "sa" identified by "pass" using 'Lnk2sql';

Database link created
