标题：11GR2升级到12CR1并插入CDB
作者：惜分飞©版权所有[未经本人同意,不得以任何形式转载,否则有进一步追究法律责任的权利.]
ORACLE 12C已经发布了十多天,其中一个亮点就是pdb,而在12C之前的数据库没有pdb之说,也就是说如果要把以前的数据库升级到12C,并且想让该库变成一个pdb,那所要做的工作就是先需要升级数据库从12C之前版本升级到12C,然后把一个NO-CDB数据库PLUG到CDB中.本blog演示:在前段时间意外的释放出来ORACLE 11.2.0.4版本,利用该版本升级到12.1.0.1,并插入到一个cdb库中
ORACLE 12C升级版本要求
11.2.0.4到12.1.0.1升级操作操作[升级整体参考文档1503653.1]

升级准备工作
执行Pre-Upgrade Utility,具体参考Note 884522.1 How to Download and Run Oracle’s Database Pre-Upgrade Utility

这里发生了改变,在12C之前版本直接显示需要修改的相关操作,12C把相关操作封装到了preupgrade_fixups.sql脚本，执行该脚本按照提示修复问题.
这里主要以下问题需要解决
|
ALTER SYSTEM SET PROCESSES=300 SCOPE=SPFILE;
@/u01/app/oracle/product/12.1/db_1/rdbms/admin/emremove.sql
@/u02/app/oracle/product/11.2/db_1/olap/admin/catnoamd.sql
EXECUTE dbms_stats.gather_dictionary_stats;
|
执行dbupgdiag.sql收集升级前信息
如果有异常核对相应的MOS文章修改,具体见Script to Collect DB Upgrade/Migrate Diagnostic Information (dbupgdiag.sql) [ID 556610.1]
dbua升级数据库
12C的dbua发生了不上变化,因为都是图形化界面,不做过多描述,贴上几幅区别较大图进行说明,关于12C的dbua变化更加详细信息请参考:Complete Checklist to Upgrade the Database to 12c Release 1 using DBUA [ID 1516557.1]

升级前后oratab信息对比
dbua使用12C环境变量shell下执行,注意不要人工修改oratab记录,执行完会自动修改
|
--升级前
[oracle@xifenfei ~]$grepora11g/etc/oratab
ora11g:/u02/app/oracle/product/11.2/db_1:N: # line added by Agent
--升级后
[oracle@xifenfei ~]$grepora11g/etc/oratab
ora11g:/u01/app/oracle/product/12.1/db_1:N: # line added by Agent
|
到此,我们可以确定11.2.0.4已经顺利升级到12.1.0.1,升级过程比较顺利,但是升级时间比较长,很可能和我的机器配置有关
NO-CDB PLUG CDB
把11.2.0.4升级到12.1.0.1的数据库插入到一个CDB数据库中,让其成为CDB一部分
