2.  錯誤處理

2.1.  ORA-31466: 未找到釋出內容

執行訂閱表資訊時，提示ORA-31466：未找到釋出內容，排查發現是沒有將變更表cdc_employee_info的查詢許可權賦予訂閱者使用者cdc_subscriber導致。

解決方法：

SQL> conn cdc_publisher/cdc_publisher

Connected.

SQL> grant select on cdc_employee_info to cdc_subscriber;

Grant succeeded.

2.2.  啟用訂閱之後，對源表進行操作，捕獲不到資料

監控SYS使用者的employee_info表，沒有出現任何異常，就是捕獲不到資料，後來我替換給backupuser使用者的employee_info表，按照以上步驟操作，就能正常捕獲到資料了，官網也沒查到相關的文件說明，很奇怪，還需要進一步研究。

2.3.  ORA-26723 建立變更集報錯

報錯內容：

ORA-26723: 使用者 "SYS" 要求角色 "DV_STREAMS_ADMIN/DV_XSTREAM_ADMIN/DV_GOLDENGATE_ADMIN"

ORA-06512: 在 "SYS.DBMS_LOGREP_UTIL", line 197

ORA-06512: 在 "SYS.DBMS_LOGREP_UTIL", line 240

ORA-06512: 在 "SYS.DBMS_CAPTURE_ADM_INTERNAL", line 391

ORA-06512: 在 line 1

ORA-06512: 在 "SYS.DBMS_CDC_PUBLISH", line 719

ORA-06512: 在 "SYS.DBMS_CDC_PUBLISH", line 927

ORA-06512: 在 line 2

 

處理辦法就是關閉dba vault。

1)      關閉資料庫；

2)      在所有節點上以oracle使用者執行：oracle> chopt disable dv

Writing to /oracle/app/oracle/product/11.2.0/install/disable_dv.log...

/usr/bin/make -f /oracle/app/oracle/product/11.2.0/rdbms/lib/ins_rdbms.mk dv_off ORACLE_HOME=/oracle/app/oracle/product/11.2.0

/usr/bin/make -f /oracle/app/oracle/product/11.2.0/rdbms/lib/ins_rdbms.mk ioracle ORACLE_HOME=/oracle/app/oracle/product/11.2.0

2.4.  ORA-31489: DDL_MARKERS 值無效

同步模式中，建立變更記錄表，執行報錯：

ORA-31489: DDL_MARKERS 值無效

ORA-06512: 在 "SYS.DBMS_CDC_PUBLISH", line 1002

ORA-06512: 在 line 2

處理：

ddl_markers預設是y,但同步得用n;

 

2.5.  啟動釋出訂閱日誌顯示
