作为一款Java程序服务器，WebLogic Server 12c将成为Oracle公司Exalogic应用程序服务器设备的主力。

根据Oracle公司官网的信息，该公司计划于12月1日的一场在线活动中发布其旗舰性应用程序服务器WebLogic的最新版本。

在WebLogic Server 12c中，字母“C”是“cloud”(即云服务)的缩写。该版本将替代上于2009年七月发布的上一个版本WebLogic Server11g。

“现在许多企业都希望使用云设备”，Oracle在其网站上的一份声明中表示。“但为了处理现有的业务，IT业者仍需要使用现有设备并为它们投资。有了Oracle WebLogic，我们可以使你在这两方面都游刃有余。”

WebLogic 12c将成为Oracle的Exalogic应用程序管理器设备中的主力，目前Exadata数据库设备以及其最新发布的公共云服务在此领域占主导地位。

通过Exalogic以及基于WebLogic的云服务，用户可以打造自己的私人云客户端，并轻松地转移应用程序。

WebLogic 12c包含了许多新特性，包括Java EE6，Active GridLink for RAC(Real Application Clusters),，Traffic Director以及Virtual Assembly Builder等。

现有的高端WebLogic 套装的售价为每个处理器45,000美元，此外每年有9,900美元的技术支持费。目前还不清楚Oracle 是否会提高WebLogic 12c的售价。

WebLogic 12c会面临许多其它Java应用服务器的竞争，包括Red Hat的JBoss以及IBM的WebSphere，甚至还有Oracle自己的GlassFish。GlassFish是Oracle通过收购Sun Microsystem得到的。

GlassFish每个处理器收费5,000美元，此外每年还有1,100美元的维护费用，大约相当于WebLogic Server标准版费用的一半。此外GlassFish还有免费的社区支持版本。

The Java app server will be key to Oracle's Exalogic application server appliance.

Oracle is planning to announce the next version of its flagship WebLogic application server during an online event Dec. 1, according to information on the company's website.

WebLogic Server 12c, in which the 'C' appears to be shorthand for "cloud," will succeed version 11g, which was first released in July 2009

"Today most businesses have the ambition to move to a cloud infrastructure," Oracle said in a statement on its site. "However, IT needs to maintain and invest in their current infrastructure for supporting today's business. With Oracle WebLogic ... we provide you with the best of both worlds."

WebLogic 12c will be key to Oracle's Exalogic application server appliance, which has so far been overshadowed by the Exadata database machine, as well as its recently announced public cloud service.

Customers will be able to build out private clouds with Exalogic as well as use Oracle's WebLogic-based public cloud service, while easily moving the applications back and forth, according to Oracle.

Features of WebLogic 12c include Java EE 6, Active GridLink for RAC (Real Application Clusters), Traffic Director, and Virtual Assembly Builder, Oracle said.

Current pricing for the high-end WebLogic Suite is $45,000 per processor, plus $9,900 in annual support. It wasn't immediately clear whether Oracle will institute a price increase upon 12c's release.

WebLogic 12c will compete with a variety of other Java application servers, including Red Hat's JBoss and IBM's WebSphere, as well as Oracle's own GlassFish, which was acquired through the purchase of Sun Microsystems.

GlassFish costs $5,000 per processor along with $1,100 in yearly maintenance fees, or about half as much as WebLogic Server Standard Edition. There is also a community-supported version of GlassFish available at no charge.
