关于虚拟机Linux重启导致ohasd和crs没有启动的处理

重启linux系统后

首先检查 ：

#su - oracle

$ cd /u01/app/oracle/product/11.2.0/grid/bin

$ ./crsctl chech has

如果显示ohasd是not online，则是没有启动

$./crs_stat -t

如果显示没有crs资源，则是资源没有启动

其次处理：

$ sh -x /u01/app/oracle/product/11.2.0/grid/bin/crsctl check has

$ cd /u01/app/oracle/product/11.2.0/grid/crs/install

$ su

$ oracle

# ./roothas.pl -deconfig -force -verbose

# cd /u01/app/oracle/product/11.2.0/grid

# ./root.sh

（如果有用到的语句dd if=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1）

再切换到oracle用户下

$ cd /u01/app/oracle/product/11.2.0/grid/bin

$ ./crsctl stat res -t //查询资源状态

$ ./crsctl start res -all //启动所有资源

Name Type Target State
Host

------------------------------------------------------------

ora.cssd ora.cssd.type ONLINE ONLINE localhost

ora.diskmon ora....on.type ONLINE ONLINE localhost

对比正常的services：
少 ora.DATA.dg / ora.asm ,先添加ora.asm
$ srvctl add asm

$ ./crsctl start res ora.asm

$ ./crs_stat -t

Name Type Target State Host

------------------------------------------------------------

ora.asm ora.asm.type ONLINE ONLINE localhost

ora.cssd ora.cssd.type ONLINE ONLINE localhost

ora.diskmon ora....on.type ONLINE ONLINE localhost

再添加ora.DATA.dg

# xhost +
#su - oracle
$ asmca
将diskgroup mount起来
$ ./crs_stat -t

之后登录sqlplus，startup等待mount上，就可以了，如果不行尝试以下步骤。

[oracle@localhost test]$ srvctl add database -d orcl -o $ORACLE_HOME

[oracle@localhost test]$ srvctl start database -d orcl

[oracle@localhost test]$ . oraenv

ORACLE_SID = [+ASM] ? +ASM

The Oracle base for ORACLE_HOME=/u01/app/oracle/product/11.2.0/grid is /u01/app/oracle
[oracle@localhost ~]$ crsctl status res -t
