探索Oracle数据库升级6

11.2.0.4.3 Upgrade12c(12.1.0.1)

一、前言：

      Oracle 12c公布距今已经一年有余了，其最大亮点是一个能够插拔的数据库(PDB)，这是在之前版本号没有的。可是假设我们要将曾经版本号的数据库升级到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括了数据库软件的升级，同一时候也包括怎样将一个NO-CDB的数据库plug
to CDB none。



二、升级要求:

三、升级前准备:

3.1、查看数据库版本号及补丁信息

四、运行预升级脚本:

4.1 依据Metalink ID:1503653 step 3中提到的到

ID:556610.1下载预升级脚本preupgrd.sql检查是否满足升级条件。

 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

      ************************************************************

SQL> 

       在这里已经把须要改动的相关操作封装到了preupgrade_fixups.sql脚本中，运行该脚本依照提示修复存在的问题就可以。

4.2 主要须要修复例如以下问题:

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 运行dbupgdiag.sql收集升级前信息

假设有异常參考Metalink
ID:556610.1进行改动。

[oracle@db01 ~]$ ll dbupgdiag.sql
-rwxr-xr-x 1 oracle oinstall 24140 Nov 20 04:52 dbupgdiag.sql

五、開始安装ORACLE 12C软件

5.1 创建12c安装所需文件夹

[oracle@db01 DBSoft]$ mkdir -p /DBSoft/Product/12.1.0/db_1

[oracle@db01 DBSoft]$ chown -R oracle:oinstall /DBSoft/Product/12.1.0
[oracle@db01 DBSoft]$ chmod -R 755 /DBSoft/Product/12.1.0
[oracle@db01 DBSoft]$ cd /DBSoft/Product/12.1.0

5.2 改动用户环境变量：

[oracle@db01 Product]$ vi ~/.bash_profile

export PATH
export EDITOR=vi
export ORACLE_SID=woo
export ORACLE_BASE=/DBSoft
export ORACLE_HOME=$ORACLE_BASE/Product/12.1.0/db_1
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export PATH=$ORACLE_HOME/bin:$PATH
umask 022 

5.3 解压缩软件:

[oracle@db01 ~]$ unzip linuxamd64_12c_database_1of2.zip
[oracle@db01 ~]$ unzip linuxamd64_12c_database_2of2.zip

六、開始安装12c软件:

     6.1 进入解压文件夹运行./runInstaller 开启12c安装进程

6.2 直接点击Next，下一步開始安装

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 选择全部的语言，点击Next

6.6 选择第一个选项 EntePrise Edition (6.4GB)

6.7 指定Oracle 12c的安装文件夹，会从环境变量中自己主动读取，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 開始安装

6.10 開始安装，这个过程等待约15分钟

6.11 弹出提示运行root.sh脚本

6.12 开启新窗体，通过root用户登录，运行root.sh脚本

6.13 运行完root.sh脚本后，点击完毕，自己主动弹出监听配置。開始配置监听

6.14 配置监听名称，默认就可以

6.15 选择监听可用的协议。通常配置TCP就能够了

6.16 配置port。使用默认的1521，点击就可以

6.17 问你是否还须要配置其它监听，选择No。点击Next就可以

6.18 这步提示是否须要创建一个用于client连接的服务，选择No。点击Next就可以

6.19 点击Finish，完毕网络的配置

6.20 如今開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 选择须要升级的数据库。点击Next

6.22 运行升级检查。选择fix，后点击Next

6.23 配置升级选项，全部的都选上。设置和CPU数量同样的并行度。点击Next

6.24 选择EM配置，点击Next

6.25 升级是否移动数据文件。这里不须要移动，点击Next

6.26 选择须要升级的监听。点击Next

6.27 数据恢复选项。升级前是否对数据库进行一次备份操作，选择备份，并指定路径，点击Next

6.28 检查下Summary，点击Finish開始升级

6.29 如今開始运行升级操作

6.30 至此升级已经完毕，耗时至少四个小时以上。务必预留好足够多的升级时间。

6.31 升级已经完毕，点击Next

6.32 点击Close关闭升级窗体

        至此11g upgrade 12c已经接近尾声了，兴许还须要做一些升级后的检查。

七、运行升级后的检查

7.1 Oracle 12c版本号及组件状态的检查

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  从上面我们能够看到有些组件的状态是不正确的，这是老版本号的组件，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信息对照

---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：这部分不须要我们手工去改动/etc/oratab记录，运行升级会自己主动完毕改动。

7.5 升级后运行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眼下是18。说明不须要人工处理了，假设不是须要手工来处理，參考Metalink
ID: 977512.1 或者參考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，假设是下面字符集则不须要做操作:

假设返回结果是 UTF8或者
AL16UTF16，那么什么都不须要做了。

假设返回结果不是 UTF8或者 AL16UTF16。那么请參考以下的文档：

id=276914.1">Note 276914.1 

ID 276914.1)

<strong>SQL> select value from nls_database_parameters where parameter=\'NLS_NCHAR_CHARACTERSET\';

VALUE
--------------------------------------------------------------------------------
AL16UTF16

7.8 改动參数文件里版本

SQL> show parameter compatible

------------------------------------ ----------- ------------------------------
compatible string 11.2.0.0.0
noncdb_compatible boolean FALSE

SQL> alter system set compatible = \'12.1.0.1.0\' scope=spfile;

     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，整个升级过程尽管有点长，但还是比較顺利的。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国米形式，升级的确是一个很长的时间。
