最近做了一个安装11.2.0.4.180116补丁的实验，突然想起之前和同事讨论的一个问题：如何检查数据库安装补丁的版本，之前搜到的是去查dba_registry_history，有的说在操作系统中执行./opatch lspatches查看。就做了一个实验：
前提：本系统曾前后安装了 171017和180116版本补丁，但180116补丁已回退！！
1.1 首先检查opatch工具版本：
以oracle用户登录，验证opatch 工具版本。安装补丁11.2.0.4.180116所需最低opatch版本为11.2.0.3.6。
[root@localhost ~]# su - oracle [oracle@localhost ~]$ cd $ORACLE_HOME/OPatch [oracle@localhost OPatch]$ ./opatch version OPatch Version: 11.2.0.3.18 OPatch succeeded.
如果检查结果不满足，则需要升级opatch工具。若OPatch Version大于等于11.2.0.3.6则略过1.2节步骤 opatch工具版本升级。
1.2 升级opatch工具版本
以oracle用户登录，将opatch备份：
[root@localhost ~]# su - oracle [oracle@localhost ~]$ cd $ORACLE_HOME [oracle@localhost dbhome_1]$ pwd /oracle/app/oracle/product/11.2.0/dbhome_1 [oracle@localhost dbhome_1]$ mv OPatch OPatch.bak
将下载的OPatch工具包p6880880_112000_Linux-x86-64.zip上传至/home/oracle目录，进行解压缩。
[root@localhost ~]# su - oracle [oracle@localhost ~]$ unzip p6880880_112000_Linux-x86-64.zip -d $ORACLE_HOME/
重新验证OPatch工具包版本：
[oracle@localhost ~]$ cd $ORACLE_HOME [oracle@localhost dbhome_1]$ cd OPatch [oracle@localhost OPatch]$ ./opatch version OPatch Version: 11.2.0.3.18 OPatch succeeded.
1.3 安装11.2.0.4.180116补丁包
1.3.1 上传并解压缩补丁包p26925576_112040_Linux-x86-64.zip
将下载的psu补丁p26925576_112040_Linux-x86-64.zip上传至/soft目录，进行解压缩。
[root@localhost ~]# su – oracle [oracle@localhost ~]$ mkdir soft/ -- 若已存在该目录，则忽略该步骤 [oracle@localhost ~]$ cd soft/ [oracle@localhost soft]$ unzip p26925576_112040_Linux-x86-64.zip
1.3.2 停止EM
[root@localhost ~]# su - oracle [oracle@whf ~]$ emctl status dbconsole Oracle Enterprise Manager 11g Database Control Release 11.2.0.4.0 Copyright (c) 1996, 2013 Oracle Corporation.

1.3.3 停数据库、监听
[root@localhost ~]# su - oracle [oracle@localhost ~]$ sqlplus / as sysdba SQL> shutdown immediate SQL> exit [oracle@localhost ~]$ lsnrctl stop
1.3.4 opatch apply安装
opatch apply命令需要使用oracle用户，进入补丁包所在目录后执行。
[root@localhost ~]# su – oracle [oracle@localhost ~]$ cd soft/26925576/ [oracle@localhost 26925576]$ $ORACLE_HOME/OPatch/opatch apply Oracle Interim Patch Installer version 11.2.0.3.18 Copyright (c) 2018, Oracle Corporation.

1.3.5 起数据库、监听、EM
[root@localhost ~]# su - oracle [oracle@localhost ~]$ sqlplus / as sysdba SQL*Plus: Release 11.2.0.4.0 Production on Tue Feb 20 20:46:18 2018 Copyright (c) 1982, 2013, Oracle. All rights reserved.

1.3.6 将升级信息写入数据库
为了验证数据库补丁如何查看，暂时先不写入数据库，依次查看dba_registry_history和opatch lspatches版本
（本系统曾前后安装了 171017和180116版本补丁，但180116补丁已回退）：

查看opatch lapatches版本：
[oracle@localhost ~]$ cd $ORACLE_HOME/OPatch
[oracle@localhost OPatch]$ ./opatch lspatches
26925576;Database Patch Set Update : 11.2.0.4.180116 (26925576) OPatch succeeded.
故说明使用./opatch lspatches只能查看系统安装补丁版本，但不意味着数据库应用的版本信息，数据库应用的版本需使用dba_registry_history查看。
为验证说明，进行将升级信息写入数据库：
[oracle@localhost ~]$ sqlplus / as sysdba
SQL> @?/rdbms/admin/catbundle.sql psu apply 修复无效对象
SQL> @?/rdbms/admin/utlrp.sql
再次查看dba_registry_history和opatch lspatches版本：
