从 Oracle 10g 降级到 9i 时需要注意什么?
我必须将 Oracle 实例从 10g (10.1.0.2.0) 降级到 9i (9.2.xxx)。 我没有计划这样做,因此没有记录 10g 依赖项。
我必须解决哪些对 10g 的依赖性?
我可以执行任何类型的查询来检测依赖关系吗?
当然,我希望有一个灵丹妙药,而不是筛选大量添加的功能来与 100 klocs 的 PL/SQL 进行比较。
顺便说一下,我们并不是就地降级数据库,而是从 10g 实例迁移到单独的 9i 实例。
I having to downgrade my Oracle instance from 10g (10.1.0.2.0) to 9i (9.2.x.x.x).
Not having planned on ever doing this, I didn't document 10g dependencies.
What are some of the dependencies on 10g that I will have to address?
Is there any type of query that I could perform to detect dependencies?
Of course I'm hoping for a magic bullet, not sifting through volumes of feature additions to compare with 100 klocs of PL/SQL.
By the way, we are not downgrading the database in place, we are migrating from a 10g instance to a separate 9i instance.

了解Oracle 10G 新功能 文档以查看您需要不使用的内容。
Take a look at the Oracle 10G New Features documentation to see what you need to not be using.
您可以设置许多参数来实现 9i 兼容性、关闭散列分组依据等。
您可以开始使您的 10g 实例看起来更像 9i,而无需将其移动到任何地方。 不会是完美的,但这是一个开始。
There are a host of parameters you could set to put you in 9i compatibility, turn off hash group by's etc.
You could start to make your 10g instance look a lot more like 9i without moving it anywhere. Won't be perfect but it's a start.
大人物(据我所知)。 如果您有这些领域的功能,请仔细查看:
@tony-andrews :正如托尼提到的,10g 新功能文档中可能有更多细节,我确信我的模糊和无知的大脑已经遗漏了这些细节。
The biggies (that I know of). If you have functionality in these areas, take a closer look:
@tony-andrews: as Tony mentions, there's probably more details in the 10g new features documentation that I'm sure my foggy and uninformed brain has left out.
