Oracle 11g RAC ohasd failed to start at /u01/app/11.2.0/grid/crs/install/rootcrs.pl line 443 解决方法

一.问题描述

在Oracle Linux 6.1 上安装11.2.0.1 的RAC，在安装grid时执行root.sh 脚本，报错，如下：

[root@rac1 bin]#/u01/app/11.2.0/grid/root.sh

Running Oracle 11g root.sh script...

The following environment variables are setas:

ORACLE_OWNER= oracle

ORACLE_HOME= /u01/app/11.2.0/grid

Enter the full pathname of the local bindirectory: [/usr/local/bin]:

Copying dbhome to /usr/local/bin ...

Copying oraenv to /usr/local/bin ...

Copying coraenv to /usr/local/bin ...

Entries will be added to the /etc/oratabfile as needed by

Database Configuration Assistant when adatabase is created

Finished running generic part of root.shscript.

Now product-specific root actions will beperformed.

据说这个错误只在linux 6.1下，且Oracle 版本为11.2.0.1的时候出现，在11.2.0.3的时候就不会有这种问题，而解决方法就是在生成了文件/var/tmp/.oracle/npohasd文件后，root立即执行命令：

/bin/dd if=/var/tmp/.oracle/npohasd of=/dev/nullbs=1024 count=1

二．清除安装历史记录

这里有两种方法：1.清除grid，2，清除root.sh.

2.1 清除GRID

在我们继续执行之前先清除GRID，具体步骤参考：

RAC 卸载说明

http://blog.csdn.net/tianlesoftware/article/details/5892225

在所有节点执行：

rm –rf /etc/oracle/*

rm -rf /etc/init.d/init.cssd

rm -rf /etc/init.d/init.crs

rm -rf /etc/init.d/init.crsd

rm -rf /etc/init.d/init.evmd

rm -rf /etc/rc2.d/K96init.crs

rm -rf /etc/rc2.d/S96init.crs

rm -rf /etc/rc3.d/K96init.crs

rm -rf /etc/rc3.d/S96init.crs

rm -rf /etc/rc5.d/K96init.crs

rm -rf /etc/rc5.d/S96init.crs

rm -rf /etc/oracle/scls_scr

rm -rf /etc/inittab.crs

rm -rf /var/tmp/.oracle/*

rm -rf /tmp/.oracle/*

移除ocr.loc 文件，通常在/etc/oracle 目录下：

[root@rac1 ~]# cd /etc/oracle

You have new mail in /var/spool/mail/root

[root@rac1 oracle]# ls

lastgasp ocr.loc ocr.loc.orig olr.loc olr.loc.orig oprocd

[root@rac1 oracle]# rm -rf ocr.*

格式化ASM 裸设备：

[root@rac1 utl]# ll /dev/asm*

brw-rw---- 1 oracle dba 8, 17 Jun 27 09:38 /dev/asm-disk1

brw-rw---- 1 oracle dba 8, 33 Jun 27 09:38/dev/asm-disk2

brw-rw---- 1 oracle dba 8, 49 Jun 27 09:38/dev/asm-disk3

brw-rw---- 1 oracle dba 8, 65 Jun 27 09:38/dev/asm-disk4

dd if=/dev/zero of=/dev/asm-disk1 bs=1Mcount=256

dd if=/dev/zero of=/dev/asm-disk2 bs=1Mcount=256

dd if=/dev/zero of=/dev/asm-disk3 bs=1Mcount=256

dd if=/dev/zero of=/dev/asm-disk4 bs=1Mcount=256

移除/tmp/CVU* 目录：

[root@rac1 ~]# rm -rf /tmp/CVU*

删除/var/opt目录下的Oracle信息和ORACLE_BASE目录:

# rm -rf /data/oracle

# rm -rf /var/opt/oracle

删除/usr/local/bin目录下的设置：

# rm -rf /usr/local/bin/dbhome

# rm -rf /usr/local/bin/oraenv

# rm -rf /usr/local/bin/coraenv

移除Grid 安装目录，并重建：

[root@rac1 oracle]# rm -rf /u01/app

[root@rac2 u01]# mkdir -p /u01/app/11.2.0/grid

[root@rac2 u01]# mkdir -p/u01/app/oracle/product/11.2.0/db_1

[root@rac2 u01]# chown -R oracle:oinstall/u01

[root@rac2 u01]# chmod -R775 /u01/

2.2 清除root.sh 记录

使用rootcrs.pl 命令来清楚记录，命令如下：

[root@rac1 oracle]#/u01/app/11.2.0/grid/crs/install/rootcrs.pl-deconfig -verbose -force

三．重新安装并处理问题

在执行/u01/app/11.2.0/grid/root.sh脚本的时候开2个root的shell窗口，一个用来执行脚本，一个用来监控/var/tmp/.oracle/npohasd文件，看到就用root立即执行命令：

/bin/ddif=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1

[root@rac1 oracle]#/u01/app/11.2.0/grid/root.sh

Running Oracle 11g root.sh script...

The following environment variables are setas:

ORACLE_OWNER= oracle

ORACLE_HOME= /u01/app/11.2.0/grid

Enter the full pathname of the local bindirectory: [/usr/local/bin]:

The file "dbhome" already existsin /usr/local/bin. Overwrite it? (y/n)

--------注意-------------

看到root.sh 执行到这里的时候，我们就可以在另一个窗口不断的刷我们的dd命令了，如果有更好的方法也可以，我这里是这么操作的：
