HP-unix下安裝11G RAC出現的問題（三）

1萬個人安裝RAC能裝出10萬個為什麼，果然沒錯。安裝過程伴隨著一些坎坷。如何解除安裝CRS呢？METALINK給出了解除安裝的安裝文件收錄一下：

3.卸掉一些相關的東東：

rm -f /tmp/.oracle

cd /var/opt

# rm -Rf oracle

# cd /var/tmp

# rm -Rf .oracle

4.卸掉ORA_CRS_HOME東西：

rm -Rf /home/oracle/crs

rm -Rf /home/oracle/oinventory

5.別忘了心跳磁碟也要清除

# dd if=/dev/zero f=/dev/vx/rdsk/voddg/ocr bs=1024 count=10000

# dd if=/dev/zero f=/dev/vx/rdsk/voddg/voting  bs=1024 count=10000

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:

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
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/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

   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. Remove the CRS install location:

  rm -Rf /*

8. De-install the CRS home in the Oracle Universal Installer

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
