安装clusterware时如果出现报错现象,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。
我们也可以采用手工删除
1、在所有节点停止nodeapps
srvctl stop nodeapps -n nodename
|
2、删除自动启动程序
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 universal installer卸载crs
7、删除crs安装目录
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
