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

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

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

再次查看dba_registry_history和opatch lspatches版本：
