探索Oracle之数据库升级六
11.2.0.4.3 Upgrade12c(12.1.0.1)
一、前言：
Oracle 12c发布距今已经一年有余了，其最大亮点是一个可以插拔的数据库(PDB)，这是在之前版本没有的；但是如果我们要将以前版本的数据库升级到12c来，那么也应顺其自然的将其变成一个pdb，那么我们的工作不仅包含了数据库软件的升级，同时也包含如何将一个NO-CDB的数据库plug to CDB none。
二、升级要求:
三、升级前准备:
3.1、查看数据库版本及补丁信息

四、执行预升级脚本:
4.1 根据Metalink ID:1503653 step 3中提到的到Metalink ID:556610.1下载预升级脚本preupgrd.sql检查是否满足升级条件。
[oracle@db01 ~]$ sqlplus / as sysdba @preupgrd.sql

The following are *** ERROR LEVEL CONDITIONS *** that must be addressed
prior to attempting your upgrade.
Failure to do so will result in a failed upgrade.
1) Check Tag: PURGE_RECYCLEBIN
Check Summary: Check that recycle bin is empty prior to upgrade
Fixup Summary:
\"The recycle bin will be purged.\"
You MUST resolve the above error prior to upgrade

在这里已经把需要修改的相关操作封装到了preupgrade_fixups.sql脚本中，执行该脚本按照提示修复存在的问题即可。
4.2 主要需要修复如下问题:
ALTER SYSTEM SET PROCESSES=300 SCOPE=SPFILE;
@$ORACLE_HOME/rdbms/admin/emremove.sql
@$ORACLE_HOME/olap/admin/catnoamd.sql
EXECUTE dbms_stats.gather_dictionary_stats;
4.3 执行dbupgdiag.sql收集升级前信息
如果有异常参考Metalink ID:556610.1进行修改。
[oracle@db01 ~]$ ll dbupgdiag.sql

5.3 解压缩软件:
[oracle@db01 ~]$ unzip linuxamd64_12c_database_1of2.zip [oracle@db01 ~]$ unzip linuxamd64_12c_database_2of2.zip
六、开始安装12c软件:
6.1 进入解压目录执行./runInstaller 开启12c安装进程
6.2 直接点击Next，下一步开始安装
6.3 选择skip software updates，点击Next
6.4 选择最后一个选项 Upgrade an existing database，点击Next
6.5 选择所有的语言，点击Next
6.6 选择第一个选项 EntePrise Edition (6.4GB)
6.7 指定Oracle 12c的安装目录，会从环境变量中自动读取，点击Next
6.8 安装Oracle的所属组和用户，无误后点击Next
6.9 检查Oracle 12c的安装信息，无误后点击Install 开始安装
6.10 开始安装，这个过程等待约15分钟
6.11 弹出提示执行root.sh脚本
6.12 开启新窗口，通过root用户登录，执行root.sh脚本
6.13 执行完root.sh脚本后，点击完成，自动弹出监听配置，开始配置监听
6.14 配置监听名称，默认即可
6.15 选择监听可用的协议，通常配置TCP就可以了
6.16 配置端口，使用默认的1521，点击即可
6.17 问你是否还需要配置其他监听，选择No，点击Next即可
6.18 这步提示是否需要创建一个用于客户端连接的服务，选择No，点击Next即可
6.19 点击Finish，完成网络的配置
6.20 现在开始对数据库进行升级(DBUA)，选择第一个选项Upgrade Oracle Database，选择Next
6.21 选择需要升级的数据库，点击Next
6.22 执行升级检查，选择fix，后点击Next
6.23 配置升级选项，所有的都选上，设置和CPU数量相同的并行度，点击Next

6.32 点击Close关闭升级窗口
至此11g upgrade 12c已经接近尾声了，后续还需要做一些升级后的检查。
七、执行升级后的检查
7.1 Oracle 12c版本及组件状态的检查
SQL> select banner from v$version;
BANNER
--------------------------------------------------------------------------------
Oracle Database 12c Enterprise Edition Release 12.1.0.1.0 - 64bit Production
PL/SQL Release 12.1.0.1.0 - Production
CORE 12.1.0.1.0 Production
TNS for Linux: Version 12.1.0.1.0 - Production
NLSRTL Version 12.1.0.1.0 – Production
SQL> set pagesize 500
SQL> set line 300
SQL> col comp_name format a40
SQL> col comp_name format a35
SQL> col version format a15
SQL> col status format a7
SQL> select comp_name,version,status from dba_registry;
COMP_NAME VERSION STATUS
----------------------------------- --------------- -------
Oracle Application Express 4.2.0.00.27 VALID
OWB 11.2.0.3.0 VALID
OLAP Catalog 11.2.0.4.0 OPTION
OFF
Spatial 12.1.0.1.0 VALID
Oracle Multimedia 12.1.0.1.0 VALID
Oracle XML Database 12.1.0.1.0 VALID
Oracle Text 12.1.0.1.0 VALID
Oracle Workspace Manager 12.1.0.1.0 VALID
Oracle Database Catalog Views 12.1.0.1.0 VALID
Oracle Database Packages and Types 12.1.0.1.0 VALID
JServer JAVA Virtual Machine 12.1.0.1.0 VALID
Oracle XDK 12.1.0.1.0 VALID
Oracle Database Java Packages 12.1.0.1.0 VALID
OLAP Analytic Workspace 12.1.0.1.0 VALID
Oracle OLAP API 12.1.0.1.0 VALID
15 rows selected.
7.2 从上面我们可以看到有些组件的状态是不对的，这是老版本的组件，不能直接通过升级上SQL进行删除
SQL> @$ORACLE_HOME/rdbms/admin/emremove.sql SQL> @$ORACLE_HOME/olap/admin/catnoamd.sql SQL> EXECUTE dbms_stats.gather_dictionary_stats;
7.3 再次查看就没有问题了:
SQL> select comp_name,version,status from dba_registry; COMP_NAME VERSION STATUS ----------------------------------- --------------- ------- Oracle Application Express 4.2.0.00.27 VALID OWB 11.2.0.3.0 VALID Spatial 12.1.0.1.0 VALID Oracle Multimedia 12.1.0.1.0 VALID Oracle XML Database 12.1.0.1.0 VALID Oracle Text 12.1.0.1.0 VALID Oracle Workspace Manager 12.1.0.1.0 VALID Oracle Database Catalog Views 12.1.0.1.0 VALID Oracle Database Packages and Types 12.1.0.1.0 VALID JServer JAVA Virtual Machine 12.1.0.1.0 VALID Oracle XDK 12.1.0.1.0 VALID Oracle Database Java Packages 12.1.0.1.0 VALID OLAP Analytic Workspace 12.1.0.1.0 VALID Oracle OLAP API 12.1.0.1.0 VALID 14 rows selected.
7.4 /etc/oratab信息对比
---升级前 [root@db01 ~]# grep DBSoft /etc/oratab woo:/DBSoft/Product/11.2.0/db_1:N ---升级后 [root@db01 ~]# grep DBSoft /etc/oratab woo:/DBSoft/Product/12.1.0/db_1:N
注意：这部分不需要我们手工去修改/etc/oratab记录，执行升级会自动完成修改。
7.5 升级后执行postupgrade_fixups.sql检查
SQL> @/DBSoft/cfgtoollogs/woo/preupgrade/postupgrade_fixups.sql

7.6 检查DST
从升级后的检查结果来看，DST目前是18，说明不需要人工处理了，如果不是需要手工来处理，参考Metalink ID: 977512.1 或者参考Metalink ID 1585343.1
SQL> r
1 SELECT PROPERTY_NAME, SUBSTR(property_value, 1, 30) value
2 FROM DATABASE_PROPERTIES
3 WHERE PROPERTY_NAME LIKE \'DST_%\'
4* ORDER BY PROPERTY_NAME
PROPERTY_NAME VALUE
---------------------------------------- ------------------------------------------------------------------------------------------------------------------------
DST_PRIMARY_TT_VERSION 18
DST_SECONDARY_TT_VERSION 0
DST_UPGRADE_STATE NONE
SQL> select * from v$timezone_file;
FILENAME VERSION CON_ID
-------------------- ---------- ----------
timezlrg_18.dat 18 0
SQL> select TZ_VERSION from registry$database;
TZ_VERSION
----------
18
7.7 字符集检查
检查国家字符集，如果是以下字符集则不需要做操作:
如果返回结果是 UTF8或者 AL16UTF16，那么什么都不需要做了。
如果返回结果不是 UTF8或者 AL16UTF16，那么请参考下面的文档：
ID 276914.1)
<strong>SQL> select value from nls_database_parameters where parameter=\'NLS_NCHAR_CHARACTERSET\'; VALUE -------------------------------------------------------------------------------- AL16UTF16 </strong>
7.8 修改参数文件中版本号
SQL> show parameter compatible NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ compatible string 11.2.0.0.0 noncdb_compatible boolean FALSE SQL> alter system set compatible = \'12.1.0.1.0\' scope=spfile; System altered.

至此，经过漫长而辛苦的升级，我们已经将11.2.0.4顺利升级到了12.1.0.1，整个升级过程虽然有点长，但还是比较顺利的。故需再生产环境中升级请大家务必预留好可用于升级的时间窗口，升级时间确实是非常的长。
