1、在AIX系統上創建簡單的定時任務

?

任務名稱：定時刪除某個目錄下的所有dbf文件

?

步驟一：創建腳本mydel.sh，放在home/目錄下，腳本內容如下

#! /bin/sh rm /orabak/archive/*.dbf

?

步驟二：加入定時執行的任務

#crontab -e

內容如下：

59 15 28 * * /bin/sh /home/mydel.sh

基本格式 :
*　*　*　*　*　command
分　時　日　月　周　命令
第1列表示分鐘1～59 每分鐘用*或者 */1表示
第2列表示小時1～23（0表示0點）
第3列表示日期1～31
第4列表示月份1～12
第5列標識號星期0～6（0表示星期天）
第6列要運行的命令

?

查看定時任務的命令為：crontab -l

?

另：vi編輯器中的簡單命令

插入：i

刪除：x

退出保存：wq!

?

2、文件系統中目錄擴容

故障描述：

Connect /as sysdba
ERROR：
ORA-09817：write to audit file failed
IBM AIX RISC system/6000 Error：28：no space left on device
ORA-09945：unable to initialize the audit trail file
IBM AIX RISC system/6000 Error：28：no space left on device

?

擴展oracle安裝目錄空間大小
