SQL Translation Framework  


SQL Translation Framework  帮助用户从SQL SERver/DB2 迁移到ORACLE时一些语法可以直接翻译成用户想要的ORACLE的形式，七主要构成是 Translator 和 Translation Profiles，Oracle官方现在还不推荐在产品环境中运行Translator ，因为翻译本身是成本很高的，切无法保证翻译出来的一定是 有效 且高效的。  换句话说，用户将不得不冒风险来跑未知的查询或者更新。

而那些已经被测试为恰当的，被接受的翻译集合，将被存放在Translation Profiles中，可以被移到开发和测试实例 用在产品环境中。

a) Do you have any links w.r.t pt#2 (internal/external) and best practices document ?
b) While moving from traditional single tenant architecture (AS-IS) to multi-tenant (To-Be), what architectural/design changes do we forsee and recommend ?
c) Do we have any customer names yet who moved their production to 12c (multi-tenant/consolidation) ?


Oracle Database 12c is production quality code. It has been very thoroughly tested prior to release. This is not a beta release.
Yes we have a thoroughly documented and tested upgrade path from Oracle Database 11g to 12c, including the adoption of the non-CDB as a PDB.
Oracle Multitenant is a new option with Oracle Database 12c. The licensed option is required when two or more PDBs are created in a single CDB. A single PDB in a CDB is called the single tenant configuration of the multitenant architecture. This does not require or trigger the licensed option. Refer to the price list and related documentation as usual for licensing and pricing details.
The Oracle Multitenant licensed option is available in Enterprise Edition only. Single tenant configuration is supported on Standard Edition. However, if you want to consolidate multiple databases as PDBs in a CDB you require EE and the Multitenant option to be licensed. There is no per-PDB license. In your customer's case, To consolidate the 11gR2 databases, SE databases and SE1 databases using Multitenant you will need to upgrade these databases to Oracle Database 12c and adopt each of them as a PDB in one or more CDBs, licensed appropriately as I've just explained.

12c中Streams的路线图将是如何？

相关的文档介绍:

From the 12c Doc: “Oracle Streams is deprecated in Oracle Database 12c and may be desupported and unavailable in a later Oracle Database release. Use Oracle GoldenGate to replace all replication features of Oracle Streams.”

Meaning of “Deprecated”:
·         Will Oracle Support assist with SRs opened on Streams

·         Are patches allowed to bug fixes.

·         Are opatch one-off patches on deprecated feature possible at all?


Meaning of “Desupported”:
·         Will Oracle Support assist with SRs opened on Streams (or is it just that bug fixes are no longer possible)?

·         Can Streams become desupported on a point release or is that potential only true for major releases?


Meaning of “Unavailable”:
·         Can Streams become decommissioned (unavailable) on a point release or is that potential only true for major releases?




Deprecated  在这里要表达的是ORACLE将不再加强该组件，不会有新的特性加入到STreams中。
STreams扔将被ORACLE支持，如果你遇到了Streams的故障或者BUG，都会给solution和开发补丁，直到ORACLE DATABASE 11.2的Extended Support ES扩展支持结束。

感觉 stream 会像 裸设备一样慢慢被排挤，最后被遗忘。
