oracle小版本升级实战

oracle11.2.0.3升级至11.2.0.4单机版

前言：

由于客户的环境有的比较老，数据库版本还停留在11.2.0.3版本，随着数据库的更新换代，以及方便以后升级到12或者18，19乃至更高的数据库版本，客户决定先升级数据库版本到11.2.0.4，于是在升级之前先在测试环境做一个测试，同时可以发现一些需要特别注意的点，在实际操作中避免失误。

上传并解压缩OracleDatabase 11.2.0.4安装介质

6.1 取消oracle支持

6.2 跳过软件更新

6.3 选择最后一个选项"Upgradean existing database" 后下一步

6.4 选择语言然后下一步

6.5 选择升级的数据库版本下一步

6.6 选择新版本数据库安装目录然后下一步

6.7 选择数据库所属用户组然后下一步

6.8 检查前置条件后下一步

6.9 察看数据库配置信息后，点击Install开始进行新版本软件安装

6.10 执行root.sh脚本

6.11 继续执行软件升级

至此11.2.0.4的软件就已经装完了，修改Oracle环境变量

拷贝监听配置文件

执行SQL

运行catupgrd.sql进行实例升级

@?/rdbms/admin/catupgrd.sql

运行utlrp.sql编译失效对象

@?/rdbms/admin/utlrp

验证升级是否完成

查看各个组件版本

selectcomp_name,status,version from dba_server_registry;

查看有无失效对象

select * fromdba_objects where status !=VALID;

补丁安装完执行应用补丁

@catbundle.sql psuapply

总结（过程中需要特别注意的点）

1.升级前的准备

升级之前做好oracle之前安装目录以及数据库的备份，升级过程中如果有问题，可以先回退，排查问题后再次升级。

2.升级完以后的注意事项

首先检查各个组件的升级情况，没问题后编译失效对象。以及根据需要安装新版本的补丁集。都做完以后，验证是否可以正常连接，正常使用。
