goldengate ERROR: Failed to open data source for user OGG

 今日做veridata軟件的測試，需要先配置一個用goldengate同步數據的環境，在目標端配置goldengate的複製進程時，使用dblogin userid ogg,password ogg命令出現錯誤

ERROR: Failed to open data source for user OGG，糾結了一兩天了，都不知道是什麼問題，好在現如今終於得到解決。配置goldengate環境是win 2008操作系統，數據庫爲11g。

在目標端安裝完goldengate,啓動了mgr進程，globals文件也配置好，執行如下命令報錯：

GGSCI (WIN-RDG14W8R3AD) 1> info all

Program     Status      Group       Lag           Time Since Chkpt

MANAGER     RUNNING


GGSCI (WIN-RDG14W8R3AD) 2> dblogin userid ogg,password ogg
ERROR: Failed to open data source for user OGG.

GGSCI (WIN-RDG14W8R3AD) 3> dblogin userid ogg,password ogg
ERROR: Failed to open data source for user OGG.

GGSCI (WIN-RDG14W8R3AD) 4> dblogin userid ogg@localhost:1521/gc,password ogg
ERROR: Failed to open data source for user OGG@LOCALHOST:1521/GC.

於是，開始排查對於權限，已給goldengate用戶授予connect,resouce,dba角色，所以在權限上ogg用戶是沒有問題的；是不是監聽的問題呢？

查看監聽沒問題，但是如果用sqlplus ogg/ogg@localhost:1521/gc 和 sqlplus ogg/[email protected]:1521/gc 都連接不進去，而使用sqlplus ogg/[email protected]:1521/gc

可以連接進去，監聽文件內容如下：

sqlnet.ora內容：
SQLNET.AUTHENTICATION_SERVICES= (NTS)

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

listener.ora內容：
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.88.18)(PORT = 1521))
    )
  )

tnsnames.ora內容：
GC =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.88.18)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = gc)
    )
  )

查看host文件內容：

127.0.0.1       localhost
::1             localhost
192.168.88.18    WIN-RDG14W8R3AD

準備重新配置監聽，將listener.ora 和tnsnames.ora裏面的host值 改成主機名，然後監聽重啓，接着用

sqlplus ogg/ogg@localhost:1521/gc 和 sqlplus ogg/[email protected]:1521/gc 

sqlplus ogg/[email protected]:1521/gc和 sqlplus ogg/ogg@WIN-RDG14W8R3AD:1521/gc 四種方式都可以連接進去。

下面再次使用dblogin命令，

 

GGSCI (WIN-RDG14W8R3AD) 6> info all

Program     Status      Group       Lag           Time Since Chkpt

MANAGER     STOPPED


GGSCI (WIN-RDG14W8R3AD) 7> dblogin userid ogg,password ogg

GGSCI (WIN-RDG14W8R3AD) 8> dblogin userid ogg@gc,password ogg
ERROR: Failed to open data source for user OGG@GC.

GGSCI (WIN-RDG14W8R3AD) 9> dblogin userid ogg@localhost:1521/gc,password ogg

 看到沒，這次進去了。。。。。

    ------------------------------------------實驗遇錯排錯記錄。中間有重新建用戶重配一樣沒解決問題。最後發現還是監聽引起的問題。
