Oracle RAC重新运行root.sh脚本

Oracle RAC重新运行root.sh脚本

----------------- 加入常用命令
vi /etc/profile
export GRID_HOME=/u01/app/12.1.0/grid
export ORACLE_HOME=/u01/app/12.1.0/grid
export PATH=$PATH:$GRID_HOME/bin


===================================rac中重新运行root.sh脚本===================================================
需要注意的是，多数以pl结尾的脚本从12.1.0.2开始都变为了sh脚本，例如：rootcrs.pl需要修改为rootcrs.sh
In 12.1.0.2, rootcrs.sh/roothas.sh should be used instead of rootcrs.pl/roothas.pl

# OCR备份，物理和逻辑都进行备份
ocrconfig -export /tmp/export_asm_lhr_logical.bak
ocrconfig -manualbackup
ocrconfig -showbackup
ocrconfig -copy +MGMT:/raclhr-cluster/OCRBACKUP/backup_20190822_085506.ocr.285.1016960109 /tmp/export_asm_lhr_physical.bak #从12.2开始的OCR物理备份默认放在MGMT磁盘组，建议单独cp到FS中
cp /u01/app/11.2.0/grid/cdata/raclhr-cluster/backup_20190822_111554.ocr /tmp/export_asm_lhr_physical.bak
#手动对集群相关资源进行备份，包括新增的db、监听、service等

#保证集群完全关闭，最好重启OS，检查网络情况，是否有cvuqdisk
#find /u01 -name cvuqdisk*
#rpm -qa cvuqdisk
#rpm -ivh $GRID_HOME/cv/rpm/cvuqdisk-*.rpm
#检查配置文件（$ORACLE_HOME/crs/install/crsconfig_params）是否需要修改，18c可以去掉MGMTDB
$GRID_HOME/root.sh  #若出现错误，则在解决错误后可以重复执行，不需要先deconfig

#也可以图形化界面使用GRID配置 
#export DISPLAY=192.168.59.1:0.0
#$ORACLE_HOME/crs/config/config.sh



-----------------------------------------------------
--- 对于18c，需要注意：
#若MGMTDB不需要重复创建，则可以修改配置文件
#配置文件（$ORACLE_HOME/crs/install/crsconfig_params）修改以下内容的值为空：
