計劃做一次備份還原測試，在另外一臺服務器上安裝好了SAP和nbu client，拷貝backint和配置文件到適當目錄，並按實際情況做修改，但是在nbu 服務器端驗證客戶端時提示：cannot connect on socket，檢查了網絡和hosts文件都沒有問題，最後一氣之下重新安裝，又自己好了，搞不懂！
完事後使用brbackup測試備份的時候一直提示輸入oracle的密碼都不對，按網上的方法：
conn / AS SYSDBA 登陸
alter user sys identified by 新密碼
alter user system identified by 新密碼
------------------------------------------------------
修改完oracle的密碼，然後嘗試登錄sqlplus
sqlplus /nolog
conn /as sysdba
結果提示： “connected to an idle instance";
繼續輸入startup準備啓動實例，又提示： "insufficient privileges"
只能關閉退出。
———————————————————
使用sqlplus "/as sysdba"
startup
可以成功啓動實例，但運行brbackup
結果還是：'CONNECT system/******** AT PROF_CONN IN SYSOPER MODE'
ORA-01031: insufficient privileges
進入sqlplus
SQL> connect system as sysoper
Enter password:
ERROR:
ORA-01031: insufficient privileges
SQL> connect sys as sysdba
Enter password:
Connected.
SQL> grant sysoper to system;
Grant succeeded.
SQL> connect system as sysoper
Enter password:
Connected.
SQL>
搞定實例和權限問題

再次使用 brbackup提示libnbclient.dll，這個是因爲安裝升級包後沒有把backint.exe覆蓋，輕鬆搞定，但是運行還是出現錯誤：

睜大牛眼仔細檢查了配置文件，確實沒有發現大問題，在netbackup 服務器上看了一下日誌，發現問題在於，自己的磁帶沒有滿但全部使用過，可能Retention不同，找了一盤磁帶先過期，然後後專門劃分給這個客戶端的備份策略，果然不出現上面的錯誤，但是又出現新的錯誤：客戶端brbackup運行一會就中斷了，系統錯誤日誌：
Faulting application backint.exe, version 7.0.2010.707, time stamp 0x4c3572a3, faulting module MSVCR80.dll, version 8.0.50727.6195, time stamp 0x4dcdd833, exception code 0xc000000d, fault offset 0x000000000002a696, process id 0x5d0, application start time 0x01cc52fcca183549.
最後找到的原因居然：log下沒有見創建backint文件夾【（primary) The backint process crashes if the backint log directory is not
created or not with full permission】，賽門鐵克也太搞笑了，你的系統在安裝的時候創建個文件夾有那麼難嗎？！
創建了文件夾，還真管用，終於可以看見成功備份了。
