1. 可以配置一些Oracle用到的变量
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/app/oracle/product/11.1.0/db_1
export ORACLE_SID=NEWRAC2
ORACLE_HOSTNAME="newrac01.hq.lumigent.int"
export PATH=/u01/app/oracle/product/11.1.0/db_1/bin:$PATH
export ORA_CRS_HOME=/u01/app/crs/product/11.1.0/crs
export PATH=/u01/app/crs/product/11.1.0/crs/bin:$PATH
export ORACLE_USER=orarac
2. crsctl ，检查crs
crsctl check crs 检查crs状态
crsctl start crs 启动crs
crsctl stop crs
crsctl check crsd
crs_stat -t
等等，其 /etc/init.d/init.crs stop /etc/init.d/init.crsd stop 等开机启动service 脚本如果
如果你发现crs不能正常工作可以检查调试一下这些脚本，检查一下进程是不是这个脚本可以正常工作。
crs的启动log 在 $ORA_CRS_HOME/log $ORA_CRS_HOME/log/client 下面可以找到。出现错误可以检查一下对应的log
3. srvctl 启动数据库与实例
srvctl start database -d NEWRAC 启动名字为NEWRAC的数据库
查看当前数据库的状态
[root@newrac02 ~]# srvctl status database -d NEWRAC
Instance NEWRAC1 is running on node newrac01
Instance NEWRAC2 is running on node newrac02
srvctl start instance -d NEWRAC -i newrac1 启动某一个实例
4、检查rac的配置文件 ，可以在里面找到数据库的名字等
/u01/oradata/NEWRAC/spfileNEWRAC.ora
/u01/app/oracle/admin/NEWRAC/pfile/init.ora.5302010204445

==================================================
Day-to-day management of Oracle 10G RAC
CRS management
rnCRSCTL command control of the CRS Services local node (Oracle clusterware processes)
rn stop CRS:
rn $ crsctl stop crs or
rn $ / etc / init.crs stop or
rn $ crs_stop-all
rn start CRS:
rn $ crsctl start crs or
rn $ / etc / init.crs start
rn prohibited Clusterware restart automatically at system startup methods:
rn $ / etc / init.crs disable
rn start Clusterware restart automatically at system startup methods:
rn $ / etc / init.crs enable
rn view the status CRS Services
rn $ crsctl check crs
rnOCR resource management
rnOCR resources, when the RAC cluster up and running successfully, you can use the instrument crs_stat see the following:
rn $ ORA_CRS_HOME / bin / crs_stat
rn general, the status of all resources should be online. In addition, OCR will be four hours each to back up first. Have some cases you can restore the OCR configuration file to restore problems OCR.
rn such as the use of the following situations occur:
rn $ crs_stat-t
rnCRS-0184: Cannot communicate with the CRS daemon.
rn $ crsctl check boot
rnFailure 4 at procr_open_key with status 4.
rnPROC-4: The cluster registry key to be operated on does not exist.
rn $ crsctl check crs
rnFailure 1 contacting CSS daemon
rnCannot communicate with CRS
rnCannot communicate with EVM
rn caused this error may be due to a lost OCR configuration. We can use this backup to restore the previous configuration.
