手工升级到Oracle 12C

寻技术 Oracle 2023年11月06日 137

一、升级路线

  • 10.2.0.5，11.1.0.7，11.2.0.2以上版本可以直接升级到12c。
  • 10.2.0.5以前的版本和11.2.0.1版需要先升级到中间版本，再升级到12c。

二、环境说明

  • 操作系统：Red Hat 8 Linux 64位
  • 源数据库版本：Oracle 11.2.0.3
  • 目标数据库版本：Oracle 12.1.0.2

三、升级步骤简述

  • 备份源数据库（RMan）
  • 执行Pre-Upgrade Information Tool（preupgrd.sql）
  • 准备新版本的Oracle Home
  • 关闭数据库实例
  • 使用12c启动数据库，进入升级模式
  • 执行并行升级实用程序（catctl.pl）
  • 执行Post-Upgrade Status Tool（utlu121s.sql）
  • 执行附加脚本（catuppst.sql和utlrp.sql）
  • 完成升级阶段

四、升级步骤

4.1、备份数据库

4.2、执行Pre-Upgrade Information Tool

4.2.1、运行预升级工具脚本

使用目标版本数据库（Oracle 12C）目录/u01/app/oracle/product/12.1.0/dbhome_1/rdbms/admin/下的preupgrd.sql脚本。在源数据库的SQL*Plus内执行。

此工具是用来分析源数据库存在的问题，并生成用来生成解决问题的脚本。

Fixup Returned Information:
WARNING: --> Enterprise Manager Database Control repository found in the database

     In Oracle Database 12c, Database Control is removed during
     the upgrade. To save time during the Upgrade, this action
     can be done prior to upgrading using the following steps after
     copying rdbms/admin/emremove.sql from the new Oracle home
   - Stop EM Database Control:
    $> emctl stop dbconsole

   - Connect to the Database using the SYS account AS SYSDBA:

   SET ECHO ON;
   SET SERVEROUTPUT ON;
   @emremove.sql
     Without the set echo and serveroutput commands you will not 
     be able to follow the progress of the script.

     Note 1: To reduce database upgrade time, APEX can be manually
             upgraded outside of and prior to database upgrade.

提出的建议如下：

  • 发现了Enterprise Manager，在升级过程中会删除EM库，为了减少升级时间，可以先删除。已自动处理。

  • 发现了OLAP Catalog组件，在12C中不再支持OLAP Catalog组件，可以在升级前或升级后使用catnoamd.sql脚本删除，这里就不删除了，升级后再说。

  • 回收站是空的，不需要处理。如果回收站不是空的，将自动清空回收站。

  • 发现了APEX，APEX版本升级会占用比较多的时间，oracle建议可以手工升级，参考: 1088970.1，这里也不管了，一起升级。

  • 建议在数据库升级的24小时之前执行EXECUTE dbms_stats.gather_dictionary_stats;，收集数据字典统计信息。
1 SQL> EXECUTE dbms_stats.gather_dictionary_stats;
 4.2.3、升级后脚本

升级后在新环境运行升级后修复脚本：/u01/app/oracle/cfgtoollogs/rcat/preupgrade/postupgrade_fixups.sql，此脚本用来修复数据库升级后的问题。

4.3、准备12c Oracle Home

编辑/etc/oratab文件，将RCAT的环境变量指向Oracle 12C的Oracle Home。

1 [oracle@orasrv admin]$ vim /etc/oratab
rcat:/u01/app/oracle/product/12.1.0/dbhome_1:Y

4.4、关闭数据库实例

1 SQL> shutdown immediate

4.5、使用12c启动数据库，进入升级模式

9 LRM-00109: could not open parameter file '/u01/app/oracle/product/12.1.0/dbhome_1/dbs/initrcat.ora'

以上提示说明需要参数文件initrcat.ora，我们将11g数据库的参数文件复制到12c的相应目录

1 [oracle@orasrv ~]$ cp /u01/app/oracle/product/11.2.0/dbhome_1/dbs/spfilercat.ora /u01/app/oracle/product/12.1.0/dbhome_1/dbs/

再次启动

 1 SQL> startup upgrade

4.6、执行并行升级实用程序

在12c中，使用升级脚本catctl.pl代替了catupgrd.sql，升级脚本的执行方式也发生了变化。根据以上提示可知，在Linux环境下需按以下方式执行： 

[oracle@orasrv ~]$ cd $ORACLE_HOME/rdbms/admin
[oracle@orasrv admin]$ $ORACLE_HOME/perl/bin/perl catctl.pl -n 2 catupgrd.sql

 -n后参数2代表并行度为2，可按CPU核数进行设置。接下来就进入到漫长的升级过程：

除了OLAP Catalog组件外，其它组件都升级到希望的版本。

因不再被12c支持，可以移除OLAP Catalog组件。

1 SQL> @?/olap/admin/catnoamd.sql

4.8、执行附加脚本

执行catuppst.sql脚本完成接下来的升级操作，它不要求数据库处于升级模式。

1 SQL> @?/rdbms/admin/catuppst.sql

执行utlrp.sql脚本重新编译PL/SQL和Java代码。

1 SQL> @?/rdbms/admin/utlrp.sql

等待执行完成。

4.9、完成升级阶段

4.9.1、检查环境变量
  • ORACLE_BASE
  • ORACLE_HOME
  • PATH,LD_LIBRARY_PATH and SHLIB_PATH
  • 更新oratab文件
4.9.2、检查初始化参数文件

确认初始化参数修改正确。

4.9.3、检查口令文件

可以使用orapwd命令重建口令文件。

4.9.4、COMPATIBLE参数

COMPATIBLE参数控制数据库兼容性级别，如果数据库不会再降级到以前的版本，可以设置此参数。

1 SQL> alter system set compatible='12.1.0.2.0' scope=spfile;

重启数据库实例。

4.9.5、升级TIMEZONE文件版本

 查看数据库当前timezone 版本：

 1 SQL> SELECT PROPERTY_NAME, SUBSTR(property_value, 1, 30) value 
 2　　　 FROM DATABASE_PROPERTIES
 3      WHERE PROPERTY_NAME LIKE 'DST_%'
 4      ORDER BY PROPERTY_NAME;
 5 PROPERTY_NAME　　　　　　　　　　 VALUE
 6 ---------------------------　　---------------------------
 7 DST_PRIMARY_TT_VERSION　　　　　11 
 8 DST_SECONDARY_TT_VERSION　　　　0
 9 DST_UPGRADE_STATE　　　　　　　　NONE

1 SQL> SELECT version FROM v$timezone_file;
2 
3    VERSION
4 ----------
5         11

注意：11.2.0.1.0的timezone最高支持到11，在12.1.0.2中最高支持到18。

准备升级timezone到18

1 SQL> set serveroutput on
2 SQL> exec DBMS_DST.BEGIN_PREPARE(18);

 4.9.6、升级RMAN Recovery Catalog

如果当前库上有RMAN Catalog，可以使用UPGRADE CATALOG进行升级。

参考：https://docs.oracle.com/database/121/BRADV/rcmcatdb.htm#BRADV188

4.9.7、为Oracle XML DB配置FTP和HTTP端口以及HTTP身份验证

Oracle Database 12c DBCA不为Oracle XML DB配置端口，因此您必须手动配置它们。您还应该为HTTP配置摘要身份验证，以利用改进的安全功能。

4.9.8、启用Database Vault

Register Database Vault by using the DVSYS.DBMS_MACADM.ENABLE_DV procedure.

4.9.9、打开统一审计

4.9.10、重新注册到云控制台
