oracle和sqlserver互訪!
前幾天由於工作的原因查找了oracle中查找sqlserver數據的資料,現測試成功,整理一下貼出!
要求:從Oracle中能取SqlServer的數據
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),測試用戶:sa/pass 測試數據表: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,所以網關裝在我用的機器,網關可以裝在MSQLDB上
[B]1.通過ODBC通用方式聯接[/B]
[php]
// A. 安裝HS部件
// 默認情況下HS部件是安裝的,查詢視圖 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_HOME\\NETWORK\\ADMIN,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)) # 網關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_HOME\\NETWORK\\ADMIN
LISTENER =
(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:\oracle\ora9i)
(PROGRAM = hsodbc) # 要使用的HS服務程序.
)
)
// E. 重啟監聽器服務
// F. 編輯ORACLE_HOME\\HS\\ADMIN內init.ora，這裡是iniths4sql.ora,因為上面的SID=hs4sql
HS_FDS_CONNECT_INFO = ERPSQL # B中設置的ODBC名稱
HS_FDS_TRACE_LEVEL = 0
// G. 創建DB LINK,以及測試
SQL> create database link ora2sql connect to "sa" identified by "pass" using 'Lnk2sql';
Database link created
SQL> select ta001,ta002 from acpta@ora2sql where rownum<5;
TA001 TA002

[B]2.通過"透明網關"方式聯接[/B]
[php]
// A. 安裝透明網關,在安裝時選擇自定義安裝,安裝TRANSPARENT GATEWAY FOR SQLSERVER 組件,安裝成功後會產生oracle_home\ora90\tg4msql目錄!
// B. 配置TNSNAMES.ORA,路徑:ORACLE_HOME\\NETWORK\\ADMIN,這一步應該在ORACLEDB(192.168.1.52)上配置!
TG4MSQL = # tnsName

)

)
)
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = tg4msql)
(SID_NAME = tg4msql)
(ORACLE_HOME = D:\oracle\ora9i)
(PROGRAM= tg4msql)
)
)
// D. 重啟監聽器服務
// E. 編輯ORACLE_HOME\\TG4MSQL\\ADMIN內init.ora，這裡是inittg4msql.ora,因為上面的SID=tg4msql
#HS_FDS_CONNECT_INFO="SERVER=ERPSQL;DATABASE=EK",好多人說用這行可以,我用這行的時候出現了不能打開鏈接的錯誤,改下面一行就沒問題了!
HS_FDS_CONNECT_INFO=ERPSQL.EK
HS_FDS_TRACE_LEVEL=OFF
HS_FDS_RECOVERY_ACCOUNT=RECOVER
HS_FDS_RECOVERY_PWD=RECOVER
