How to Clean Up After a Failed Oracle Clusterware (CRS) Installation

10g RAC: How to Clean Up After a Failed CRS Install (Note 239998.1)

Not cleaning up a failed CRS install can cause problems like node reboots.
Follow these steps to clean up a failed CRS install:

不清理失败的CRS安装可能会导致节点重新启动等问题。按照以下步骤清理失败的CRS安装:

1. Run the rootdelete.sh script then the rootdeinstall.sh script from the
   $ORA_CRS_HOME/install directory on any nodes you are removing CRS from. Running
   these scripts should be sufficent to clean up your CRS install. Rootdelete.sh
   accepts options like nosharedvar/sharedvar, and nosharedhome/sharedhome. Make
   yourself familiar with these options by reading the Oracle Clusterware and
   Oracle Real Application Clusters Administration and Deployment Guide.
   If you have any problems with these scripts please open a service request.

运行 rootdelete.sh 脚本，然后运行 rootdeinstall.sh 脚本
$ORA_CRS_HOME/ 要删除CRS的任何节点上的安装目录。运行
这些脚本应该足以清理您的 CRS 安装。Rootdelete.sh
接受选项如 nosharedvar/sharedvar 和 nosharedhome/sharedhome。使
您可以通过阅读 Oracle Clusterware 和
Oracle RAC 管理和部署指南。
如果您对这些脚本有任何问题，请打开服务请求。

If for some reason you have to manually remove the install due to problems
with the scripts, continue to step 2:

如果由于某些原因，您必须手动删除安装由于脚本的问题，继续步骤2:

2. Stop the Nodeapps on all nodes:

   srvctl stop nodeapps -n <node name>

3. Prevent CRS from starting when the node boots. To do this issue the following
   as root:

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

4. If they are not already down, kill off EVM, CRS, and CSS processes or reboot
   the node:

   ps -ef | grep crs
   kill <crs pid>
   ps -ef | grep evm
   kill <evm pid>
   ps -ef | grep css
   kill <css pid>

   Do not kill any OS processes, for example icssvr_daemon process !

5. If there is no other Oracle software running (like listeners, DB’s, etc…),
   you can remove the files in /var/tmp/.oracle or /tmp/.oracle. Example:

    rm -f /var/tmp/.oracle/*
   
    or
   
    rm -f /tmp/.oracle/*
   

6. Remove the ocr.loc
   Usually the ocr.loc can be found at /etc/oracle

7. De-install the CRS home in the Oracle Universal 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=1M count=256
    dd if=/dev/zero of=/dev/rdsk/ocrV1064_100m.ora bs=1M count=256
   
    dd if=/dev/zero of=/dev/mapper/asm1 bs=1M count=256
    dd if=/dev/zero of=/dev/rhdisk1 bs=1M count=256
   

   See the Clusterware Installation Guide for sizing requirements…

   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. It is good practice to reboot the node before starting the next install.

11.If you would like to re-install CRS, follow the steps in the RAC Installation manual.

以上，特此记录之。
