如何讓 AS/400 全系統備份自動化？
AS/400 全系統備份需要在專屬模式（restrictive state）下及需要在中控台（console）
上執行備份指令才能完成，由於專屬模式下，所有的使用者作業及所有子系統均已被停止
，只有系統作業及從中控台進入系統（SignOn）的線上即時作業可以正常執行，所以我們
可以利用中控台上的線上即時作業（interactive job）自動執行全系統備份作業。
做法是：
１：從中控台進入系統（SignOn），執行下列的指令，在程式中會從訊息佇列
（message queue）中讀取訊息，訊息佇列若沒有訊息時，程式會等待有訊息時才讀取，並判斷是否執行全系統備份作業。
２：於排程作業中設定某時間傳送訊息至訊息佇列，以啟動或終止備份作業。
File : QCLSRC
Member: FULSAVC
Type : CLP
Usage :
1. 新增訊息佇列 SAVSYSMSGQ: Yourlib - 指定您自己的 Library
CRTMSGQ MSGQ(Yourlib/SAVSYSMSGQ) TEXT('Message Queue for Unattended full save')
2. 修改程式中 Yourlib - 指定您自己的 Library 及 console DSP01 --指定您自己的 console 名稱
CRTCLPGM FULSAVC
CRTCMD CMD(FULSAV) PGM(Yourlib/FULSAVC)
3. 新增自動工作排程傳送啟動備份訊息 Yourlib - 指定您自己的 Library
此範例指定，此作業於每個星期天 16:55 執行：
ADDJOBSCDE JOB(BIGSAV) CMD(SNDMSG MSG('STRSAVSYS') TOMSGQ(Yourlib/SAVSYSMSGQ))
FRQ(*WEEKLY) SCDDATE(*NONE) SCDDAY(*SUN) SCDTIME('16:55:00') JOBQ(QGPL/QBASE)
USER(QSECOFR) TEXT('Send a message to start full system save.')
如果要取消份作業，上述指令 CMD 參數更改如下：
SNDMSG MSG( 'ENDSAVSYS' ) TOMSGQ( Yourlib/SAVSYSMSGQ)
4. 於星期五下班前，從 Console Sign On 進入系統，於命令列輸入 FULSAV，系統即進入等待上述啟動備份訊息
當每個星期天 16:55 時間到達時，系統會收到訊息判斷是否啟動備份作業。
附註：
由於資料量及磁帶容量與磁帶機設備不同，所以有可能需要一卷以上的磁帶做備份，若由於設備不足，您還是
要由人工換磁帶。使用此範例前，請先測試無問題後，在正式實施。
