db2資料庫監控指令碼
主要用途

1、監控db2資料庫效能； 
2、按照監控日期生成資料夾，存放監控日誌檔案； 
3、自動清理過期日誌； 
4、可以設定監控時間間隔與監控次數； 
5、結合crontab計劃任務，可以設定何時呼叫指令碼；

注意事項

需要根據業務需要，適當設定監控頻率與監控週期；

版本移植性

因Linux與AIX在指令碼編寫上有少許差異，所以分為兩個指令碼。

Linux下db2監控指令碼
Linux版本

Oracle Linux Server release 6.7

指令碼檔案：snaps.sh

#!/bin/sh
# usage: monitor the db2 health on linux;
# std:
# 1:log dir : snaps.%Y-%m-%d 
# 2:log retains : only retain the last 7 days logs;
#
# set temp path;

# set the max monitor count;
maxCount=5
sleeptime=600
intervalCount=1

# set base dir;
base_dir=/home/db2inst1/tmp/snaps

    exit
