oracle10g 清楚crs

如果在安装clusterware的过程报错,需要重新安装时,必须先清除已经安装的cluserware,否则可能会影响到下次安装。一般情况下,只需要在各节点上依次运行目录$ORA_CRS_HOME/install/下的脚本rootdelete.sh和rootdeinstall.sh 即可。

也可以采用如下步骤手工删除:

1、在所有节点停止nodeapps

srvctl stop nodeapps -n nodename

2、删除crs自动启动程序

Sun:

rm /etc/init.d/init.cssd
rm /etc/init.d/init.crs
rm /etc/init.d/init.crsd
rm /etc/init.d/init.evmd
rm /etc/rc3.d/K96init.crs
rm /etc/rc3.d/S96init.crs
        rm -Rf /var/opt/oracle/scls_scr
        rm -Rf /var/opt/oracle/oprocd
rm /etc/inittab.crs
cp /etc/inittab.orig /etc/inittab

Linux:

        rm /etc/oracle/*
rm -f /etc/init.d/init.cssd
rm -f /etc/init.d/init.crs
rm -f /etc/init.d/init.crsd
rm -f /etc/init.d/init.evmd
rm -f /etc/rc2.d/K96init.crs
rm -f /etc/rc2.d/S96init.crs
rm -f /etc/rc3.d/K96init.crs
rm -f /etc/rc3.d/S96init.crs
rm -f /etc/rc5.d/K96init.crs
rm -f /etc/rc5.d/S96init.crs
        rm -Rf /etc/oracle/scls_scr
rm -f /etc/inittab.crs
cp /etc/inittab.orig /etc/inittab

HP-UX:

rm /sbin/init.d/init.cssd
rm /sbin/init.d/init.crs
rm /sbin/init.d/init.crsd
rm /sbin/init.d/init.evmd
        rm /sbin/rc2.d/K960init.crs
        rm /sbin/rc2.d/K001init.crs
rm /sbin/rc3.d/K960init.crs
rm /sbin/rc3.d/S960init.crs
        rm -Rf /var/opt/oracle/scls_scr
        rm -Rf /var/opt/oracle/oprocd
rm /etc/inittab.crs
cp /etc/inittab.orig /etc/inittab

HP Tru64:

rm /sbin/init.d/init.cssd
rm /sbin/init.d/init.crs
rm /sbin/init.d/init.crsd
rm /sbin/init.d/init.evmd
rm /sbin/rc3.d/K96init.crs
rm /sbin/rc3.d/S96init.crs
        rm -Rf /var/opt/oracle/scls_scr
        rm -Rf /var/opt/oracle/oprocd
rm /etc/inittab.crs
cp /etc/inittab.orig /etc/inittab

IBM AIX:

rm /etc/init.cssd
rm /etc/init.crs
rm /etc/init.crsd
rm /etc/init.evmd
rm /etc/rc.d/rc2.d/K96init.crs
rm /etc/rc.d/rc2.d/S96init.crs
        rm -Rf /etc/oracle/scls_scr
        rm -Rf /etc/oracle/oprocd
rm /etc/inittab.crs
cp /etc/inittab.orig /etc/inittab

3、kill css/crs/evm进程,并reboot节点

ps -ef | grep css/crs/evm

kill -9 processid

4、删除/tmp/.oracle或/var/tmp/.oracle

rm -f /tmp/.oracle  或rm -f /var/tmp/.oracle

5、删除ocr.loc

rm -f /etc/oracle/orc.loc

6、用oracle universal installer卸载crs

7、删除crs安装目录

rm -Rf crs_install_dir

8、使用dd清除vote disk和ocr(裸设备)

dd if=/dev/zero f=/dev/votedisk_device bs=8192 count=2560

dd if=/dev/zero f=/dev/ocr_device bs=8192 count=12800

裸设备的清除要看设备分区的大小,在决定bs 和count
