从以前的版本迁移到Oracle 12c：我是否使用多租户容器数据库（CDB）或非CDB数据库

Question

我目前正在尝试为已经开发了多年的大型项目添加Oracle 12c支持。 我们目前正在Oracle 10g上运行。

如果我运行10g中使用的脚本，使用12c创建数据库对象，则在尝试创建用户时会收到ORA-65096错误， 这在此进行描述 。

如果使用以下修复程序，则可以使用用于10g的脚本创建用户和数据库架构：

alter session set "_ORACLE_SCRIPT"=true; 

但是，当应用程序执行时，出现以下权限错误：

我认为这与用户未与CDB关联且因此对架构中的对象没有特权有关。

在开始尝试解决此问题之前，我需要确定是否需要将用户创建为CDB用户或非CDB用户。 另外，如果用户是CDB用户，我如何创建该用户应与之关联的CDB？

一些其他信息。

• 用于创建数据库对象的所有数据库交互都是通过jdbc进行的。

• 像这样启动JBoss时，应用程序通过JBoss 7.1.1-final使用hibernate将方言设置为10g作为JVM arg进行连接：Dhibernate.dialect = org.hibernate.dialect.Oracle10gDialect

• 执行以下语句以创建数据库对象：

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

完成这些步骤后，将运行一个脚本，该脚本在myapp4模式中创建表等。

Answer 1

事实证明，这里的根本问题实际上是由使用错误的jdbc驱动程序jar引起的。

通过添加已安装产品随附的odbc7.jar文件（默认情况下安装在此处\\ product \\ 12.1.0 \\ dbhome_1 \\ jdbc \\ lib），然后通过将以下jvm参数添加到jboss来设置休眠方言，可以解决此问题。启动脚本：

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

做出这些更改后，旧版10g应用程序已启动并运行，并准备在12c中进行测试。

因此，这里提出的特定问题的答案是：都没有，一旦我正确配置了所有内容，我就无法获得包含用于创建10g模式的脚本的应用程序，使其能够按原样在12c中工作。
