Oracle 11g rac 集群节点的修复过程

Oracle 11g rac 集群节点的修复过程

一、问题的产生

用户的双节点 Oracle 11g rac 集群，发现有一个节点宕机，发现集群没有启动。手工启动集群报如下错误：

[root@his02 bin]# ./crsctl start cluster
CRS-4639: Could not contact Oracle High Availability Services
CRS-4000: Command Start failed, or completed with errors.[root@his02 bin]# ./crsctl check css
CRS-4639: Could not contact Oracle High Availability Services
CRS-4000: Command Check failed, or completed with errors.

二、修复过程

1、执行 roothas.pl 命令

[root@his02 bin]# cd /u01/app/11.2.0/grid/crs/install
[root@his02 install]# ./roothas.pl -deconfig -force -verbose
Can't locate Env.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 . .) at crsconfig_lib.pm line 703.
BEGIN failed--compilation aborted at crsconfig_lib.pm line 703.
Compilation failed in require at ./roothas.pl line 166.
BEGIN failed--compilation aborted at ./roothas.pl line 166.

执行以上命令时出现错误，重新执行以下格式的命令：

[root@his02 install]# /u01/app/11.2.0/grid/perl/bin/perl /u01/app/11.2.0/grid/crs/install/rootcrs.pl -deconfig -force
Using configuration parameter file: /u01/app/11.2.0/grid/crs/install/crsconfig_params

Cannot communicate with crsdCRS-4544: Unable to connect to OHAS
CRS-4000: Command Stop failed, or completed with errors.Successfully deconfigured Oracle clusterware stack on this node

2、执行 root.sh 命令

[root@his02 grid]# ./root.sh
Check /u01/app/11.2.0/grid/install/root_his02_2024-11-13_19-10-14.log for the output of root script

执行过程中查看日志，发现如下错误：

[root@his02 ~]# tail -f /u01/app/11.2.0/grid/install/root_his02_2024-11-13_19-10-14.log
Performing root user operation for Oracle 11g The following environment variables are set as:ORACLE_OWNER= gridORACLE_HOME=  /u01/app/11.2.0/gridCopying dbhome to /usr/local/bin ...Copying oraenv to /usr/local/bin ...Copying coraenv to /usr/local/bin ...Entries will be added to the /etc/oratab file as needed by

ohasd failed to start
Failed to start the Clusterware. Last 20 lines of the alert log follow: 
[client(50691)]CRS-2101:The OLR was formatted using version 3.

该错误解决方法如下：

（1）新开一个窗口，执行如下命令：

[root@his02 install]# cd /var/tmp/.oracle/
[root@his02 .oracle]# ls
npohasd
[root@his02 .oracle]# dd if=npohasd of=/dev/null bs=1024 count=1

过一段时间，重新查看日志，发现 root.sh 命令已执行完毕，节点添加成功。

[root@his02 ~]# tail -f /u01/app/11.2.0/grid/install/root_his02_2024-11-13_19-10-14.log

（2）重启服务器，然后执行如下命令：

[root@his02 ~]# cd /var/tmp/.oracle/
[root@his02 .oracle]# ll npohasd
prw-r--r-- 1 root root 0 8月  21 14:46 npohasd
[root@his02 .oracle]# rm -rf  npohasd
[root@his02 .oracle]# touch  npohasd
[root@his02 .oracle]# chmod 755  npohasd
[root@his02 .oracle]# ll npohasd
-rwxr-xr-x 1 root root 0 8月  21 15:02 npohasd

3、查看集群信息

[root@his02 .oracle]# su - grid
上一次登录：三 11月 13 19:05:15 CST 2024pts/1 上
[grid@his02 ~]$ crs_stat -t

4、查看节点2的IP地址

[grid@his02 ~]$ ifconfig

5、查看节点2的监听信息
