標題：11GR2升級到12CR1并插入CDB
作者：惜分飛©版權所有[未經本人同意,不得以任何形式轉載,否則有進一步追究法律責任的權利.]
ORACLE 12C已經發布了十多天,其中一個亮點就是pdb,而在12C之前的數據庫沒有pdb之說,也就是說如果要把以前的數據庫升級到12C,并且想讓該庫變成一個pdb,那所要做的工作就是先需要升級數據庫從12C之前版本升級到12C,然后把一個NO-CDB數據庫PLUG到CDB中.本blog演示:在前段時間意外的釋放出來ORACLE 11.2.0.4版本,利用該版本升級到12.1.0.1,并插入到一個cdb庫中
ORACLE 12C升級版本要求
11.2.0.4到12.1.0.1升級操作操作[升級整體參考文檔1503653.1]

升級準備工作
執行Pre-Upgrade Utility,具體參考Note 884522.1 How to Download and Run Oracle’s Database Pre-Upgrade Utility

這里發生了改變,在12C之前版本直接顯示需要修改的相關操作,12C把相關操作封裝到了preupgrade_fixups.sql腳本，執行該腳本按照提示修復問題.
這里主要以下問題需要解決
|
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;
|
執行dbupgdiag.sql收集升級前信息
如果有異常核對相應的MOS文章修改,具體見Script to Collect DB Upgrade/Migrate Diagnostic Information (dbupgdiag.sql) [ID 556610.1]
dbua升級數據庫
12C的dbua發生了不上變化,因為都是圖形化界面,不做過多描述,貼上幾幅區別較大圖進行說明,關于12C的dbua變化更加詳細信息請參考:Complete Checklist to Upgrade the Database to 12c Release 1 using DBUA [ID 1516557.1]

升級前后oratab信息對比
dbua使用12C環境變量shell下執行,注意不要人工修改oratab記錄,執行完會自動修改
|
--升級前
[oracle@xifenfei ~]$grepora11g/etc/oratab
ora11g:/u02/app/oracle/product/11.2/db_1:N: # line added by Agent
--升級后
[oracle@xifenfei ~]$grepora11g/etc/oratab
ora11g:/u01/app/oracle/product/12.1/db_1:N: # line added by Agent
|
到此,我們可以確定11.2.0.4已經順利升級到12.1.0.1,升級過程比較順利,但是升級時間比較長,很可能和我的機器配置有關
NO-CDB PLUG CDB
把11.2.0.4升級到12.1.0.1的數據庫插入到一個CDB數據庫中,讓其成為CDB一部分

出現ORA-24344,但是數據庫正常open到read write模式,忽略該錯誤，繼續執行
