关于Clusterware卸载的问题？

lyh303

正在实施一套Solaris10+Sun Cluster3.2+Oracle Clusterware+Oracle10g RAC的项目，已经配置完Sun Cluster3.2和SVM，在安装完Oracle Clusterware后（安装没问题、VIP已经生效、crs_stat显示状态正常，但还未安装Oracle RAC）发现其安装目录指定在默认的$ORACLE_BASE/db_1目录下了（应该为$ORACLE_BASE/crs），为规范起见，准备卸载Clusterware软件，并重新安装指定到正确目录，但重新运行安装程序时，在安装完软件包后，提示以root用户执行下面的脚步（/opt/oracle/product/10.2.0/crs/root.sh），只提示了以root执行这一个脚本，在一个节点上执行这个脚本时就停在“Startup will be queued to init within 30 seconds”不动了，不知道什么原因？？？是不是卸载Clusterware不彻底呀？还需要做什么呢？

备注，卸载Clusterware的步骤如下：
1. Run the command CRS_home/install/rootdelete.sh to disable the Oracle Clusterware applications that are running on the cluster node.
2. Start OUI. In the Welcome page, click Deinstall Products to display the list of installed products. Select the Oracle Clusterware home to de-install.

不记得卸载时还有运行root.sh呀

guyeh

需要在RAC的每个节点上都运行CRS_home/install/rootdelete.sh和CRS_home/install/rootdeinstall.sh

问题解决了，的确是卸载的不彻底导致，后来在metalink上找到一篇文档，安装文档做了一遍reboot系统后，问题解决。感谢楼上几位的支持！

对了，把那个文档贴出来，供大家参考：

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

PURPOSE

The purpose of this document is to help DBA's and support analysts understand how
to clean up a failed CRS (Cluster Ready Services) install for 10g RAC.

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 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:

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 <CRS Install Location>/*

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.

请教一下？

suncluster与clusterware的作用是不是重叠？只用一种群集管理软件是不是也可以实现RAC？

不重叠, Oracle clusterware可以使用suncluster的某些功能, 比如集群管理, 比如裸设备管理.

10g RAC必须安装Oracle clusterware, suncluster可以装, 也可以不装

我郁闷了2天asm，最后更换硬盘才解决。
