Linux上安装RAC失败,彻底清楚CRS步骤如下:
1、在所有节点停止nodeapps
srvctl stop nodeapps -n nodename
2、删除crs自动启动程序
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
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
