写了下db2巡检的一个小脚本，只能做常规检查，减少日常工作量，脚本内容如下：

#!/bash/bin


echo "物理CPU个数为："
cat /proc/cpuinfo| grep "cpu cores"| uniq


echo "逻辑CPU个数为："
cat /proc/cpuinfo| grep "processor"| wc -l


echo "内存空间为："
sed -n '/MemTotal/p' /proc/meminfo


echo "swap空间大小为："
sed -n '/SwapTotal/p' /proc/meminfo


echo "系统资源使用情况："
top -d 2 -n 1


echo "文件系统使用情况为："
df -h


echo "db2版本为："
db2level


echo "检查db2主进程："
ps  -ef  | grep db2sysc


echo "检查所有可用数据库："
db2 list active databases|grep 'Database name'|awk -F '[=]' '{print $2}'
db2 list active databases|grep 'Database name'|awk -F '[=]' '{print $2}' > aaa.txt


echo "检查所有数据库表空间状态："
cat aaa.txt |while read line  
do  
  echo "数据库$line:";
  db2 connect to $line;
  db2 "select char(TBSP_NAME,50) as TBSP_NAME, TBSP_USABLE_PAGES, TBSP_USED_PAGES, rtrim(100*TBSP_USED_PAGES/TBSP_USABLE_PAGES)||'%' as USED_RATE from sysibmadm.SNAPTBSP_PART where TBSP_USABLE_PAGES>0 order by TBSP_NAME,DBPARTITIONNUM";
done


echo "查看备份状态："
cat aaa.txt |while read line  
do  
  echo "数据库$line:";
  db2 connect to $line;
  db2 list history backup all for $line;
done

rm -rf aaa.txt


echo "常规检查完成"
