1.备份

su - grid -c "crsctl status res -t"
cat /proc/meminfo | grep HugePagesls -lrt /dev/ls -lrt /dev/sd*ls -lrt /dev/asm*cat  /etc/udev/rules.d/asm***df -hmountfree -g/etc/security/limits.conf/etc/hosts/etc/selinux/config /etc/pam.d/system-auth-ac/etc/sysctl.conf /etc/resolv.conf/etc/ssh/sshd_config /etc/pam.d/susysctl  -a

2.查补丁

select d.action,d.version,d.action_time from dba_registry_history d;
1	APPLY	11.2.0.4	24-AUG-13 12.03.45.119862 PM
2	APPLY	11.2.0.4	27-APR-23 05.37.57.255365 AM

3.操作

在这里插入代码片1.软件备份
tar -cvf /u01.tar /u01
2.启动集群
/u01/11.2.0/grid/bin/crsctl start crs
chown oracle:oinstall -R /tmp/31305209/
3.验证一致性
<ORACLE_HOME>/OPatch/opatch lsinventory -detail -oh <ORACLE_HOME>catalog start with '/home/oracle/arch'
