crs安装失败后清除
我们知道，在安装oracle10grac的过程中，由于各种各样的原因，经常会遇到crs安装失败的情形。
并且，crs不单单在在CRS_HOME中写入文件，在系统目录中也会写入一些文件，为了保证下次安装时有一个干净的环境，需要我们去完整的清理这些失败安装文件。
一般情况下，在CRS_HOME的install目录下，会有rootdelete.sh，rootdeinstall.sh等等，可以运行这些脚本来进行CRS的清理。
但是，某些情况下，在这些脚本无法正常清理时，需要通过以下步骤进行手工清理。
1.停止所有nodeapp应用：
srvctlstopnodeapps-n
2.使用root用户，将crs自启动脚本全部删除，各平台下文件路径不同，供参考：
Sun:

rm-Rf/var/opt/oracle/oprocd
rm/etc/inittab.crs
cp/etc/inittab.orig/etc/inittab

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
HPTru64:
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-Rf/etc/oracle/scls_scr
rm-Rf/etc/oracle/oprocd
rm/etc/inittab.crs
cp/etc/inittab.orig/etc/inittab
3.遗留进程清理，包括EVM,CRS,CSS，但是要注意，不要将操作系统进程误杀，如icssvr_daemon
ps-ef|grepcrs
kill
ps-ef|grepevm
kill
ps-ef|grepcss
kill
4.删除临时目录中的oracle文件，确认无其他oracle进程正在运行
rm-f/var/tmp/.oracle/* or rm-f/tmp/.oracle/*
5.删除ocr.loc文件，通常在/etc/oracle目录下，如果没有，使用find命令搜一下
root:
find/-nameocr.loc
6.通过OracleUniversalInstaller将CRS软件进行deinstall
7.删除oraclecrs安装目录
8.清除ocr及votingdisk信息，如果使用文件系统，直接删除，如果使用裸设备，使用dd命令进行清理，如：
ddif=/dev/zeroof=/dev/rdsk/voting_disk1.dbfbs=1Mcount=256
ddif=/dev/zeroof=/dev/rdsk/ocr1.dbfbs=1Mcount=256
9.如果可以的话，建议重启主机一次，再进行下一次CRS的完整安装。
