11.2.0.4 RAC 手动打补丁

1. 下载补丁和最新OPatch
GI PSU : p25869727_112040_Linux-x86-64.zip
OPatch : p6880880_112000_Linux-x86-64.zip

说明：GI PSU包括DB PSU,CPU。单机与RAC的opatch通用，单机与rac的psu不通用。

2. 检查数据库当前OPatch版本

RAC所有节点的GI home和DB home都需要检查。
$ $ORACLE_HOME/OPatch/opatch version

3. 更新OPatch,RAC所有节点的GI home和DB home都需要更新。
3.1 更新grid用户的OPatch
-- grid用户操作
node1-> echo $ORACLE_HOME
/u01/app/11.2.0/grid

-- root用户执行，/u01/app/11.2.0/grid/为grid用户下的$ORACLE_HOME路径
[root@node1 tmp]# mv /u01/app/11.2.0/grid/OPatch /u01/app/11.2.0/grid/OPatch_bak
[root@node1 tmp]# ll p6880880_112000_Linux-x86-64.zip
-rw-r--r--. 1 grid oinstall 99065778 Aug 3 03:07 p6880880_112000_Linux-x86-64.zip
[root@node1 tmp]# unzip p6880880_112000_Linux-x86-64.zip -d /u01/app/11.2.0/grid/
[root@node1 tmp]# chown -R grid:oinstall /u01/app/11.2.0/grid/OPatch

-- grid用户操作
node1-> $ORACLE_HOME/OPatch/opatch version
OPatch Version: 11.2.0.3.16
OPatch succeeded.

说明：需要注意grid用户$ORACLE_HOME 权限。

3.2 更新oracle用户的OPatch
-- oracle用户执行
node1-> echo $ORACLE_HOME
/u01/app/oracle/product/11.2.0/db_1

-- root用户执行，/u01/app/oracle/product/11.2.0/db_1 为oracle用户下的$ORACLE_HOME路径
[root@node1 tmp]# mv /u01/app/oracle/product/11.2.0/db_1/OPatch /u01/app/oracle/product/11.2.0/db_1/OPatch_bak
[root@node1 tmp]# unzip p6880880_112000_Linux-x86-64.zip -d /u01/app/oracle/product/11.2.0/db_1/
[root@node1 tmp]# chown -R oracle:oinstall /u01/app/oracle/product/11.2.0/db_1/OPatch

-- oracle用户操作
node1-> $ORACLE_HOME/OPatch/opatch version
OPatch Version: 11.2.0.3.16
OPatch succeeded.

4. 解压补丁文件 （所有节点的 grid,oracle都要解压psu文件）
-- root用户执行

[root@node1 tmp]# unzip p26030799_112040_Linux-x86-64.zip -d /tmp/grid_psu/
[root@node1 tmp]# chown -R grid:oinstall /tmp/grid_psu/

[root@node1 tmp]# unzip p26030799_112040_Linux-x86-64.zip -d /tmp/ora_psu/
[root@node1 tmp]# chown -R oracle:oinstall /tmp/ora_psu/

5. 所有节点都要检查补丁之间有无冲突
5.1 Node1节点 grid用户检查
grid用户执行结果:
node1-> cd 26030799/
node1-> $ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -ph ./

5.2 Node1节点 oracle用户检查

Prereq "checkConflictAgainstOHWithDetail" passed.

OPatch succeeded.

6. 为数据库做冷备份 （如果不考虑安全性，这步可以省略，有点点风险）

RMAN>run {
shutdown immediate;
startup mount;
allocate channel c1 type disk;
allocate channel c2 type disk;
backup full tag='db_full_bak' database format '/home/oracle/rmanbak/full_cold_%d_%s.bak';
alter database open;
}

使用root用户备份oracle_home （将#ORACLE_HOME上级目录整个备份）
tar -zcvpf db_20170802.tar.gz dbhome_1/

7. 停止 node1 数据库实例 和 node1 crs服务

root用户登录节点1

-- root用户执行，/u01/app/11.2.0/grid/ 为grid用户的 $ORACLE_HOME
[root@node1 bin]# ./srvctl stop instance -d devdb -i devdb1 (停node1的数据库实例)
[root@node1 bin]# /u01/app/11.2.0/grid/crs/install/rootcrs.pl -unlock
Using configuration parameter file: /u01/app/11.2.0/grid/crs/install/crsconfig_params
CRS-2791: Starting shutdown of Oracle High Availability Services-managed resources on 'node1'
.....
Successfully unlock /u01/app/11.2.0/grid

8. 手动更新补丁
8.1 节点1 grid 用户执行

node1-> $ORACLE_HOME/OPatch/opatch napply -oh $ORACLE_HOME -local /tmp/grid_psu/26030799/
输出略..
OPatch succeeded.

8.2 节点1 oracle 用户执行
[oracle@jyracdb1 ~]$ $ORACLE_HOME/OPatch/opatch napply -oh $ORACLE_HOME -local /tmp/grid_psu/26030799/25869727/
输出略..
OPatch succeeded.

8.3 执行rootadd_rdbms.sh 、rootcrs.pl -patch

su – root
[root@node1 26030799]# /u01/app/11.2.0/grid/rdbms/install/rootadd_rdbms.sh
[root@node1 26030799]# /u01/app/11.2.0/grid/crs/install/rootcrs.pl -patch
Using configuration parameter file: /u01/app/11.2.0/grid/crs/install/crsconfig_params
Installing Trace File Analyzer
CRS-4123: Oracle High Availability Services has been started.

8.4 启动 node1 数据库实例 和 node1 crs服务(实际上前面执行 rootcrs.pl -patch 已经让node1的crs起来了)
[root@node1 bin]# ./srvctl start instance -d devdb -i devdb1

8.5 然后在节点2重复节点1（停止节点二数据库和节点二crs服务、grid、oracle打补丁、rootadd_rdbms.sh 、rootcrs.pl -patch）操作

9. 升级字典操作（升级数据库字典，要停业务。如果打补丁在DBCA之前，则不需要升级数据库字典，反之则需要升级数据库字典）

由于RAC实际只有一个数据库，因此任意节点登录数据库执行1次即可。最后重启数据库。

9.1 关闭数据库实例及相关进程 (静态监听、动态监听、EOM、相关服务)
--停止数据库外部进程
[root@11g ~]#ps -ef|grep -v grep |grep LOCAL=NO|awk '{print $2}'|xargs kill -9
[oracle@11g rmanbak]$ cat /home/oracle/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
[root@node1 bin]# ./srvctl stop listener
[root@node1 bin]# ./srvctl status listener
[oracle@11g rmanbak]$ ps -ef |grep ora_|grep -v grep
[oracle@11g rmanbak]$ netstat -an |grep 1521
[oracle@11g rmanbak]$ netstat -an |grep 1158
[root@node1 bin]# ./srvctl stop database -d devdb

9.2 正式升级数据库的数据字典
[root@node1 bin]# ./srvctl start database -d devdb
node1-> sqlplus / as sysdba
SQL> @$ORACLE_HOME/rdbms/admin/catbundle.sql psu apply
SQL> @$ORACLE_HOME/rdbms/admin/utlrp.sql
[root@node1 bin]# ./srvctl stop database -d devdb
[root@node1 bin]# ./srvctl start database -d devdb

10. 验证补丁更新结果

各节点的GI HOME和ORACLE HOME都执行验证。

11. 启动监听，对外提供服务，查看监听是否正常
[root@node1 bin]# ./srvctl start listener
[root@node1 bin]# ./srvctl status listener
