11.2.0.4 RAC 某系统主库使用auto rolling的方式打补丁
在一节点执行1-5，结束后然后在二节点执行1-5，结束后最后再在某个节点执行6。

1.backup GI_HOME&DB_HOME

su - root
cd /u01/app/oracle/product/11.2.0/
tar -czvpf /u01/backup/db_1.tar.gz db_1
ls -lrt /u01/backup/db_1.tar.gz

cd /u01/app/
tar -czvpf /u01/backup/grid.tar.gz grid

2.update OPatch

su - root
cd /u01/app/grid
mv OPatch OPatch.bak0617
unzip /u01/software/p6880880_112000_Linux-x86-64.zip -d /u01/app/grid/
chown -R grid:oinstall OPatch
chmod -R 755 OPatch

cd /u01/app/oracle/product/11.2.0/db_1
mv OPatch OPatch.bak0617
unzip /u01/software/p6880880_112000_Linux-x86-64.zip -d /u01/app/oracle/product/11.2.0/db_1/
chown -R oracle:oinstall OPatch
chmod -R 755 OPatch

/u01/app/oracle/product/11.2.0/db_1/OPatch/opatch version
/u01/app/grid/OPatch/opatch version

-- Validation of Oracle Inventory
/u01/app/oracle/product/11.2.0/db_1/OPatch/opatch lsinventory -detail -oh /u01/app/oracle/product/11.2.0/db_1/
/u01/app/grid/OPatch/opatch lsinventory -detail -oh /u01/app/grid/

3. unzip

su - grid
cd /u01/software
unzip p31718723_112040_Linux-x86-64.zip
chmod -R 775 31718723
cd 31718723
$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -ph ./

4.opatch auto

su -root
/u01/app/grid/OPatch/opatch auto /u01/software/31718723

5.check

/u01/app/grid/OPatch/opatch lsinv
crsctl stat res -t

6. Loading Modified SQL Files into the Database

su - oracle
cd $ORACLE_HOME/rdbms/admin
sqlplus /nolog
SQL> CONNECT / AS SYSDBA
SQL> --STARTUP
SQL> @catbundle.sql psu apply
SQL> @utlrp.sql

--check
set linesize 300
col ACTION_TIME for a40
col ACTION for a10
col NAMESPACE for a10
col VERSION for a10
col COMMENTS for a40
select * from dba_registry_history;

总结：
1.保留权限备份。
tar -czvpf fabu.tar.gz fabu --打包
tar -zxvpf fabu.tar.gz fabu --解包

2.执行@catbundle.sql psu apply时可能输出不正常，可以重复执行。

3.auto方式无需手动启停集群，auto会自动启停，并且打补丁大部分时间是耗在集群的启停上。

4.rollback

As root user, execute the following command on each node of the cluster.
# opatch auto /u01/software/31718723 -rollback

su - oracle
cd $ORACLE_HOME/rdbms/admin
sqlplus /nolog
SQL> CONNECT / AS SYSDBA
SQL> STARTUP
SQL> @catbundle_PSU_<database SID PREFIX>_ROLLBACK.sql
SQL> @utlrp.sql
