10g RAC: How to Clean Up After a Failed CRS Install
---------------------------------------------------
 
Not cleaning up a failed CRS install can cause problems like node reboots.
Follow these steps to clean up a failed CRS install:

1. Run the rootdelete.sh script. then the rootdeinstall.sh script. from the
$ORA_CRS_HOME/install directory.  Running these scripts should be sufficent
to clean up your CRS install.  If you have any problems with these scripts
please open a service request. 

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

注:步骤一的两个脚本如果能正常运行,就相当于执行了步骤2-4,再接着执行第
         5步骤,如果无法正常运行以上两个脚本,则执行以下步骤

2. Stop the Nodeapps on all nodes:

    srvctl stop nodeapps -n

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

注:每个操作系统脚本的存放路径是不一样的
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 -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
    ps -ef | grep evm
    kill
    ps -ef | grep css   
    kill

或者执行:ps -ef | grep d.bin来检查服务是否还在运行

   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 f=/dev/rdsk/V1064_vote_01_20m.dbf bs=8192 count=2560
        dd if=/dev/zero f=/dev/rdsk/ocrV1064_100m.ora bs=8192 count=12800

说明:dd命令为清空lv的文件头,其中of=后面为要清空内容的lv, bs=8192代表8k
            count=lv size (k)/ 8
如:orc 的lv的大小如果为128m, 则当bs=8192时,
       128m=131072k, count=131072k / 8k = 16384

   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.
