從以前的版本遷移到Oracle 12c：我是否使用多租戶容器數據庫（CDB）或非CDB數據庫

Question

我目前正在嘗試為已經開發了多年的大型項目添加Oracle 12c支持。 我們目前正在Oracle 10g上運行。

如果我運行10g中使用的腳本，使用12c創建數據庫對象，則在嘗試創建用戶時會收到ORA-65096錯誤， 這在此進行描述 。

如果使用以下修復程序，則可以使用用於10g的腳本創建用戶和數據庫架構：

alter session set "_ORACLE_SCRIPT"=true; 

但是，當應用程序執行時，出現以下權限錯誤：

我認為這與用戶未與CDB關聯且因此對架構中的對象沒有特權有關。

在開始嘗試解決此問題之前，我需要確定是否需要將用戶創建為CDB用戶或非CDB用戶。 另外，如果用戶是CDB用戶，我如何創建該用戶應與之關聯的CDB？

一些其他信息。

• 用於創建數據庫對象的所有數據庫交互都是通過jdbc進行的。

• 像這樣啟動JBoss時，應用程序通過JBoss 7.1.1-final使用hibernate將方言設置為10g作為JVM arg進行連接：Dhibernate.dialect = org.hibernate.dialect.Oracle10gDialect

• 執行以下語句以創建數據庫對象：

alter session set \"_ORACLE_SCRIPT\"=true

create tablespace myapp4 datafile 'myapp4.dbf' size 100M reuse
  autoextend on next 500M maxsize 25000M

create user myapp4 identified by myapp4

grant all privileges to myapp4

alter user myapp4 quota unlimited on myapp4

完成這些步驟后，將運行一個腳本，該腳本在myapp4模式中創建表等。

Answer 1

事實證明，這里的根本問題實際上是由使用錯誤的jdbc驅動程序jar引起的。

通過添加已安裝產品隨附的odbc7.jar文件（默認情況下安裝在此處\\ product \\ 12.1.0 \\ dbhome_1 \\ jdbc \\ lib），然后通過將以下jvm參數添加到jboss來設置休眠方言，可以解決此問題。啟動腳本：

-Dhibernate.dialect = org.hibernate.dialect.Oracle10gDialect

做出這些更改后，舊版10g應用程序已啟動並運行，並准備在12c中進行測試。

因此，這里提出的特定問題的答案是：都沒有，一旦我正確配置了所有內容，我就無法獲得包含用於創建10g模式的腳本的應用程序，使其能夠按原樣在12c中工作。
