探索Oracle之数据库升级六
11.2.0.4.3 Upgrade12c(12.2.0.1)

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。

 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

       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 
-rwxr-xr-x 1 oracle oinstall 24140 Nov 20 04:52 dbupgdiag.sql
