请注意，Oracle 在官方Support 网站上明确提出不支持VMWare 运行Oracle database。
但如果在虚拟环境要怎么办呢？
我的建议：
如果你就是企业用户，所有基础架构都用了VMWare，那就用VMWare，也没有发现有什么不妥的，用吧。
如果你是集成商，要给客户找不同的方案，那你要提醒一下最终用户，以免有问题找后账。
如果你是数据库服务提供商，你可以说可以用，但原厂不支持。有事找VMWare。
如果你是日常维护的DBA，你不要管是在实体机还是虚拟机上。 ：）

Purpose
---------
Explain to customers how Oracle supports our products when running on VMware
Scope & Application
----------------------
For Customers running Oracle products on VMware virtualized environments.
No limitation on use or distribution.
Support Status for VMware Virtualized Environments
--------------------------------------------------
Oracle has not certified any of its products on VMware virtualized
environments. Oracle Support will assist customers running Oracle products
on VMware in the following manner: Oracle will only provide
support for issues that either are known to occur on the native OS, or
can be demonstrated not to be as a result of running on VMware.
If a problem is a known Oracle issue, Oracle support will recommend the
appropriate solution on the native OS. If that solution does not work in
the VMware virtualized environment, the customer will be referred to VMware
for support. When the customer can demonstrate that the Oracle solution
does not work when running on the native OS, Oracle will resume support,
including logging a bug with Oracle Development for investigation if required.
If the problem is determined not to be a known Oracle issue, we will refer
the customer to VMware for support. When the customer can demonstrate
that the issue occurs when running on the native OS, Oracle will resume
support, including logging a bug with Oracle Development for investigation
if required.
NOTE: Oracle has not certified any of its products on VMware. For Oracle RAC, Oracle will only
accept Service Requests as described in this note on Oracle RAC 11.2.0.2 and later
releases.
