注意：這裏爲了驗證表空間時間點恢復只會回退要操作的表空間。所以在刪除crm 表空間上的表數據後，給jxc表空間再添加一些數據，待回退crm表空間後，恢復該表空間上刪除的表數據。如果jxc表空間上的表數據沒丟失的話，則驗證了表空間時間點恢復只會回退要操作的表空間。

6 創建輔助實例的初始化參數文件
[oracle@source /]$ cd $ORACLE_HOME/dbs
[oracle@source dbs]$ cp initCRM.ora initAUX.ora
更改 initAUX.ora內容如下
[oracle@source dbs]$ cat initAUX.ora
*.compatible='11.2.0.0.0'
*.control_files='/backup/control04.ctl'
*.db_block_size=8192
*.db_name=CRM
*.db_unique_name=_CRM
*.db_file_name_convert=('/oracle/CRM/CRM/','/backup/')
*.log_file_name_convert=('/oracle/CRM/CRM/','/backup/')
*.remote_login_passwordfile='EXCLUSIVE'
參數介紹如下：
db_name:屬於必須有的參數,該值須和目標數據庫配置一樣。
db_unique_name:屬於必須有的參數,一般該值指定爲_dbname即可。
compatible：屬於必須有的參數，該值需和目標庫一致。
db_block_size:屬於必須有的參數，該值需和目標數據庫一致。
remote_login_passwordfile：屬於必須有的參數，當用一個密碼文件連接輔助實例時，該值必須設置成EXCLUSIVE,其它爲NONE。
control_files：屬於非必須參數，該值指定文件名只要不和目標數據庫或者其它任意文件名衝突即可。
db_file_name_convert：屬於非必須參數，通過指定該值自動轉換路徑生成輔助實例所需的數據文件。
log_file_name_convert：屬於非必須參數，該值基於目標數據庫的日誌文件名，轉換路徑後生成輔助實例的聯機日誌文件。
7 創建輔助實例的密碼文件
[oracle@dest CRM]$ cd /ORACLE_HOME/dbs
[oracle@dest dbs]$ ls
01om0ebc_1_1 hc_CRM.dat initAUX.ora lkDCTA_TSPITR_CRM spfileCRM.ora
06om0ek7_1_1 hc_DBUA0.dat initCRM.ora orapwCRM
hc_AUX.dat hc_DctA.dat lkCRM snapcf_CRM.f
[oracle@dest dbs]$ cp orapwCRM orapwAUX
8 創建連接輔助數據庫的服務名
