五、总结 － 及其他说明/TIPS/文中提到的有用脚本：
从上面的配置及测试我们可以看到，只要掌握了应用程序的启动、关闭、检查的方法，我们就完全可以
利用Oracle CRS来搭建一般应用程序的高可用集群，从而保证了业务的连续性。
1.简单错误处理：如果在实施或测试过程中命令失败，或者有错误需要回退状态，
或者删除资源及相关信息，可以使用下面的几个命令：
crs_stop -f db
crs_unregister db
crs_profile -delete db
错误二：我在上面启动虚拟IP资源的时候报错：
root@rac01 # crs_start –all
….
Attempting to start `havip` on member `rac01`
`havip` on member `rac01` has experienced an unrecoverable failure.
Human intervention required to resume its availability.
…..
查看crs日志：

2008-01-10 17:30:22.527: [ CRSRES][1580] Attempting to start `dg` on member `rac01`

2008-01-10 17:30:22.758: [ CRSRES][1581] Human intervention required to resume its availability.
2008-01-10 17:30:23.211: [ CRSRES][1580] Start of `dg` on member `rac01` succeeded.
这时候发现在输入网卡时候不小心输入了错误的网卡名称，公共网卡名称应该是e1000g0，
结果使用的bge0，使用下面命令修改
root@rac01 # crs_profile -update havip -o oi=e1000g0
再次启动资源成功。
2.文中的sysdba命令是我习惯用的alias，需要在oracle的.bash_profile或者.profile中添加：
alias sysdba="sqlplus '/as sysdba'"
文中的命令crs_start/crs_stop/crs_profile/crs_register等命令位于$CRS_HOME/bin/目录下，
为了使用方面，一般需要手工将该PATH添加到root和oracle的PATH环境变量中去。
3.磁盘组的启动、关闭、监测脚本db.sh
#!/bin/sh
# *****************************************************************
# shahand 2008-1-3
SCRIPT=$0
ACTION=$1 # Action (start, stop or check)
DG_NAME=oradata12
VOL_NAME=oradata
case $1 in
'start')
/usr/sbin/vxdg -tfC import $DG_NAME;
/usr/sbin/vxvol -g $DG_NAME startall
echo "Resource STARTED"
;;
'stop')
/usr/sbin/vxvol -g $DG_NAME stopall;
/usr/sbin/vxdg deport $DG_NAME
echo "Resource STOPPED"
;;
'check')
if [[ `/usr/sbin/vxprint -v -g $DG_NAME |grep $VOL_NAME|wc -c` -eq 0 ]]
then
exit 1
else
exit 0
fi
echo "Resource CHECKED"
;;
*)
echo "usage: $0 {start stop check}"
;;
esac
exit 0
4.文件系统的启动、关闭、监测脚本fs.sh
#!/bin/sh
# *****************************************************************
# shahand 2008-1-3
SCRIPT=$0
ACTION=$1 # Action (start, stop or check)
DG_NAME=oradata12
VOL_NAME=oradata
case $1 in
'start')
mount -F vxfs /dev/vx/dsk/$DG_NAME/$VOL_NAME /oradata
echo "Resource STARTED"
;;
'stop')
umount /oradata
echo "Resource STOPPED"
;;
'check')
if [[ `mount |grep $VOL_NAME |wc -c` -eq 0 ]]
then
exit 1
else
exit 0
fi
echo "Resource CHECKED"
;;
*)
echo "usage: $0 {start stop check}"
;;
esac
exit 0
5. 数据库的启动、关闭、监测脚本db.sh
#!/bin/sh
# *****************************************************************
# ## shahand 2008-1-3
# *****************************************************************
# /oracle/crs/crs/public/db.sh
SCRIPT=$0
ACTION=$1 # Action (start, stop or check)
CRS_HOME=/oracle/crs/
case $1 in
'start')
su - oracle -c "export ORACLE_SID=orcl;
sqlplus /nolog <<EOF
connect /as sysdba;
startup;
exit;
EOF"
exit $?
;;
'stop')
su - oracle -c "export ORACLE_SID=orcl;
sqlplus /nolog <<EOF1
connect /as sysdba;
alter system checkpoint;
shutdown immediate;
exit;
EOF1"
exit $?
;;
'check')
if [ ! -f $CRS_HOME/crs/public/db.sql ]
then
echo "connect /as sysdba;" > $CRS_HOME/crs/public/db.sql;
echo "spool /tmp/db_check.out;" >>$CRS_HOME/crs/public/db.sql;
echo "select status from v\$instance ;" >> $CRS_HOME/crs/public/db.sql;
echo "exit;" >> $CRS_HOME/crs/public/db.sql;
fi
su - oracle -c "export ORACLE_SID=orcl;sqlplus /nolog @$CRS_HOME/crs/public/db.sql";
if [ `cat /tmp/db_check.out|grep OPEN|wc -c` -eq 0 ]
then
exit 1
else
exit 0
fi
;;
*)
echo "usage: $0 {start stop check}"
;;
esac
exit 0
5. 监听的启动、关闭、监测脚本lsnr.sh
#!/bin/sh
# *****************************************************************
# ## shahand 2008-1-3
# *****************************************************************
# /oracle/crs/crs/public/lsnr.sh
SCRIPT=$0
ACTION=$1 # Action (start, stop or check)
case $1 in
'start')
su - oracle -c "lsnrctl start"
exit $?
;;
'stop')
su - oracle -c "lsnrctl stop"
exit $?
;;
'check')
if [ `ps -ef|grep tnslsnr |wc -c` -eq 0 ]
then
echo "bad";
exit 1
else
echo "good";
exit 0
fi
;;
*)
echo "usage: $0 {start stop check}"
;;
esac
exit 0
7.Oracle集群软件的安装响应文件crs.rsp ，其中在####之前需要修改
ORACLE_HOME="/oracle/crs"
sl_tableList={"rac01:rac01-priv:rac01-vip:N:Y","rac02:rac02-priv:rac02-vip:N:Y"}
