如何完全删除CRS

环境:

OS:Red Hat Linux As 5

DB:10.2.0.1

 

  在安装好CRS后发现CRS无法启动,每次CRS启动异常都导致机器不停的重启动,超级郁闷,获取日志信息如下:
2012-08-01 11:50:18.491: [ CSSCLNT][5177872]clsssInitNative: connect failed, rc 9
2012-08-01 12:15:47.441: [ CSSCLNT][5547712]clsssInitNative: connect failed, rc 9
2012-08-02 09:03:11.045: [ CSSCLNT][9479872]clsssInitNative: connect failed, rc 9

  网上说引起这个问题的原因很多,能找到的办法都尝过了,问题依旧,最后回想想第一次安装CRS后不成功,可能是没有完全删除导致的,最后在网上找到了一份完全删除CRS的方法,按照这个方法完全删除后重新安装CRS,问题解决.

 

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

 

[oracle@node1 ]$ echo $ORA_CRS_HOME
/u01/app/oracle/product/10.2.0/crs_1
[oracle@node1 ]$su
[oracle@node1 ]#/u01/app/oracle/product/10.2.0/crs_1/install/rootdelete.sh
[oracle@node1 ]#/u01/app/oracle/product/10.2.0/crs_1/install/rootdeinstall.sh

 

2. Stop the Nodeapps on all nodes:
srvctl stop nodeapps -n node1

 

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
    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. 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
   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.
