oracle11g GI+RAC卸载

一、关库停资源

需要注意的是，使用root用户来停

The deconfig command below can be executed in parallel on all the remote nodes. Execute the command on the local node after the execution completes on all the remote nodes.

Run the following command as the root user or the administrator on node “host02”.

Press Enter after you finish running the above commands

<----------------------------------------

我是一路默认跑下去的，当然也要看一看有些配置与默认是否不同，注意在执行结束时要运行我标记的这个脚本

脚本又需要root执行

三、卸载后检查确认

1、检查各个节点的/etc/inittab文件，ohasd的内容应该被删除了。
2、检查每个节点是否存在ora或d.bin的进程运行，有即kill掉。
3、铲掉$GRID_HOME和$ORACLE_HOME目录。

先铲gi（顺序无所谓）

[root@host01 deinstall]# rm -rf /u01/app/11.2.0/grid/
[root@host01 deinstall]# ll /u01/app/11.2.0/grid/
ls: /u01/app/11.2.0/grid/: No such file or directory

再铲oracle
[oracle@host01-+ASM1 ~]$ rm -rf /u01/app/oracle/product/11.2.0/dbhome_1/
[oracle@host01-+ASM1 ~]$ ll /u01/app/oracle/product/11.2.0/dbhome_1/
ls: /u01/app/oracle/product/11.2.0/dbhome_1/: No such file or directory

四、删除磁盘
[oracle@host01-+ASM1 ~]$ /sbin/service oracleasm listdisks
DATA01
DATA02
DGRAC01
DGRAC02
DGRAC03
DGRAC04
DGRAC05
RECO01
RECO02
TEST01
TEST02
TEST03

因为我的环境还要用到asm磁盘，就不删除了，删除命令

oracleasm deletedisk 磁盘名

在最后还要去 /u01/app/oraInventory/ContentsXML/inventory.xml这个文件把gi的目录和oracle的目录信息删除，这样在下次重装软件的时候不会出现问题，当然，oraInventory这个目录也可以直接删除
[oracle@host01-+ASM1 ContentsXML]$ vi /u01/app/oraInventory/ContentsXML/inventory.xml

<?xml version="1.0" standalone="yes" ?>
<!-- Copyright (c) 1999, 2011, Oracle. All rights reserved. -->
<!-- Do not modify the contents of this file by hand. -->
<INVENTORY>
<VERSION_INFO><SAVED_WITH>11.2.0.3.0</SAVED_WITH><MINIMUM_VER>2.1.0.6.0</MINIMUM_VER>
</VERSION_INFO>
<HOME_LIST>
<HOME NAME="OraDb11g_home1" LOC="/u01/app/oracle/product/11.2.0/dbhome_1" TYPE="O" IDX="2">  这里删掉<NODE_LIST><NODE NAME="host01"/><NODE NAME="host02"/></NODE_LIST>
</HOME>
<HOME NAME="Ora11g_gridinfrahome1" LOC="/u01/app/11.2.0/grid" TYPE="O" IDX="1" REMOVED="T"/> 这里删掉
</HOME_LIST>
<COMPOSITEHOME_LIST>
</COMPOSITEHOME_LIST>
</INVENTORY>
~
"/u01/app/oraInventory/ContentsXML/inventory.xml" 20L, 645C   10,1          All

至此删除全部完成。
