1.主庫新增新的表空間，備庫中的STANDBY_FILE_MANAGEMENT引數設定為AUTO
2.主庫：192.168.14.112
3.備庫: 192.168.14.111

檢視備庫是否為STANDBY_FILE_MANAGEMENT引數是否為AUTO

==================================
步驟一:如果表空間上面有user請先刪除user

SQL> drop user ×× cascade

說明： 刪除了user，只是刪除了該user下的schema objects，是不會刪除相應的tablespace的。

步驟二:刪除tablespace

SQL> DROP TABLESPACE testabc01 INCLUDING CONTENTS AND DATAFILES;

oracle 11g r2 dataguard同步表空間ok.

#這裡測試的是Oracle 11g R2 11.2.0.3 DataGuard   在以上的引數環境下是OK的，但向下版情況還不是很清楚
