Oracle Study之--Oracle 单实例11.2.0.1.0升级到11.2.0.3.0
系统环境：
操作系统：RedHat EL6(64位）
Oracle： Oracle 11gR2
Oracle 11.2.0.1 单实例升级到11.2.0.3
Oracle 升级的步骤都差点儿相同，先升级Oracle software，然后升级Oracle instance。
Oracle 11.2.0.2的patchset No 是：10098816。 关于该Patchset 的下载地址，參考以下的链接：
Oracle 11.2.0.2 Patch 说明 http://www.linuxidc.com/Linux/2011-10/44230.htm
Oracle11.2.0.3 的Patchset no是：10404530，下载地址：http://www.linuxidc.com/Linux/2011-10/44229.htm
Oracle 11.2.0.3 Patchset 下载地址
patchset 有7个文件。关于这7个文件的不同作用。參考：
Oracle 11gR2 Patchset 不同文件作用说明 http://www.linuxidc.com/Linux/2011-09/43889.htm
我们升级DB。 仅仅须要当中的第一个和第二个文件。将2个文件解压缩，然后将第二个文件的内容copy到第一个文件的相应文件夹里。即将2个文件合成一个文件。
一.查看DB 相关的信息
32位的DB：

二.升级的相关说明
2.1 Patchset 的说明
内容copy 自patchset的readme 文档：
Oracle Databasepatch set, release 11.2.0.3（11.2.0.2） is a full installation of the Oracle Database software. This meansthat you do not need to install Oracle Database 11g Release 2 (11.2.0.1)before installing Oracle Database 11g Release 2 (11.2.0.3/11.2.0.2).
Oracle 11.2.0.2 和 11.2.0.3 的patchset都是完整的安装包。
所以能够直接用来安装。
Note the following changes with the newpatch set packaging:
（1）Newinstallations consist of installing the most recent patch set, rather thaninstalling a base release and then upgrading to a patch release.
（2）Directupgrades from previous releases to the most recent patch set are supported.
（3）Out-of-placepatch set upgrades recommended, in which you install the patch set into a new,separate Oracle home. In-place upgrades are supported, but not recommended.
2.1.1 In-Place Upgrade
This feature enablesyou to upgrade an existing installation of Oracle database to Oracle Database11g Release 2 (11.2.0.3) into the same Oracle home directory by replacingthe existing database files. The patch set application requires more downtimeand is
not recommended. This upgrade type requires less disk space.
将升级文件安装到原来的Oracle home 文件夹，这样能够节省磁盘空间，可是须要很多其它的downtime。 这样的并不推荐。
2.1.2 Out-of-Place Upgrade
This featureenables you to install Oracle Database 11g Release 2 (11.2.0.3) in a new,separate Oracle home directory. After the installation is complete, the datafrom the database in the old Oracle home directory is migrated to the databasein the new
Oracle home directory.
能够将Oracle Database 安装的新的OracleHome directory。当安装结束后，旧的database 会迁移到新的Oracle homedirectory。
Out-of-placeupgrade process is similar to Oracle database upgrade from one version toanother and is the recommended type. The benefits of this upgrade type is thatthe patch set application requires much less downtime, and is safer when thepatch set application
must be aborted. This upgrade type requires more diskspace to accommodate two Oracle home directories simultaneously.
这样的方法是oracle推荐的方式。它能够减少downtime 时间，也相对更安全。可是这样的方法须要2倍的地盘空间，只是对与如今白菜价硬盘来说。这点空间也不算什么了。
2.2 升级步骤
Oracle 10g的Readme上有具体的升级步骤，可是11g的Readme上并没有具体的升级说明。须要參考官方文档。
Oracle 10g upgrade from10.2.0.1 to 10.2.0.4 见 http://www.linuxidc.com/Linux/2011-05/35997.htm
（1） 备份数据库
（2） 执行patchset。升级oracle 软件
（3） 准备新的ORACLE_HOME
（4） 执行dbua 或者脚本升级实例
（5） 检查升级后的版本号信息和无效对象
官网地址：
Upgrading to theNew Release
http://download.oracle.com/docs/cd/E11882_01/server.112/e23633/upgrade.htm#i1011372
单实例的升级。相对较简单。假设是RAC的升级，预计还要麻烦一点。11gR2 RAC 升级后面会继续进行測试。
三.升级Oracle 软件
3.1 备份DB
本机是測试环境。就不进行备份，假设是生产环境，切记要先备份。后操作。
假设是In-Place Upgrade。同一时候备份一下整个ORACLE_HOME文件夹。
假设升级有问题，还能够还原回来。
重点是例如以下文件夹：
ORACLE_HOME/dbs
ORACLE_HOME/network/admin
ORACLE_HOME/hostname_dbname
ORACLE_HOME/oc4j/j2ee/OC4J_DBConsole_hostname_dbname
3.2 升级Oracle database 软件
将升级包解压。11.2.0.3总共7个升级包，仅仅须要前两个
