step by step清理安装失败的oracle 10g RAC环境(二)
Installer
8. Remove the CRS install location:
rm -Rf /*
9. Clean out the OCR and Voting Files with dd commands. Example:
dd if=/dev/zero of=/dev/rdsk/V1064_vote_01_20m.dbf bs=8192 count=2560
dd if=/dev/zero of=/dev/rdsk/ocrV1064_100m.ora bs=8192 count=12800
If you placed the OCR and voting disk on a shared filesystem, remove them.
If you are removing the RDBMS installation, also clean out any ASM disks if
they have already been used.
10.If you would like to re-install CRS, follow the steps in the RAC Installation manual
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

rm -f /etc/rc5.d/K96init.crs
rm -f /etc/rc5.d/S96init.crs
rm -Rf /etc/oracle/scls_scr
cp /etc/inittab.orig /etc/inittab

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
清除 /etc/oratab
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
