随着Oracle12c的推出，越来越多的Oracle用户都希望能够尽快的使用该版本，感受一下Oracle12c数据库强大的功能。ArcGIS软件也不例外，前一段时间Oracle12c刚推出不久，本博客就发布了怎么在Linux环境下安装Oracle12c，当时ArcGIS10.2版本还没有在中国正式发布，但是美国的Support明确说明，当时ArcGIS10.2还不支持Oracle12c，不过我断定不久可能就会支持，也许ArcGIS10.2发布某个补丁后就支持了。果然没错，在ArcGIS10.2.1版本发布之后，Esri就宣布支持Oracle12c.
关于Oracle12c的安装可以参考：
http://blog.csdn.net/linghe301/article/details/9221665
下面我们看一下ArcSDE10.2 for Oracle的系统需求，看看有什么可以注意的信息：
关于这些信息都需要用户在立项时候考虑的，更多参考：
介绍一下我安装的环境：
OS：Linux 5.5 Oracle12.1.0.1 IP：192.168.220.203 实例名：orcl
OS：Windows Server 2008，Oracle 11.2.0.2 IntantClient，ArcGIS10.2.1 for Desktop

因为目前ArcSDE10.2.1没有Oracle12c的介质软件，所以，直接使用桌面创建地理数据库即可。
确保桌面机器能够正确连接上Oracle12c的服务器端，使用建库工具
该界面与原来的Oracle11g的安装基本一样，点击执行，信息提示报：ora-65096错误
Executing: CreateEnterpriseGeodatabase Oracle 192.168.220.203/orcl # DATABASE_AUTH sys ***** SDE_SCHEMA sde ***** sde C:\Users\Administrator\Desktop\ArcGISforServerAdvancedEnterprise_server.ecp Start Time: Wed Feb 12 09:17:20 2014 User has privileges required to create database objects.

比较纳闷，在以前版本都没有问题，为什么oracle 12c环境报该错误呢？
翻开Oracle12c的新特性，曾经介绍过有一个多租户的概念
在Oracle Database 12c中，可组装式数据库 - Pluggable Database为云计算而生。在12c以前，Oracle数据库是通过Schema来进行用户模式隔离的，现在，可组装式数据库可以让此前意义上的多个数据库一起共存。
Pluggable Database 其体系结构的核心是：
由一个容器数据库(CDB)和多个可组装式数据库(PDB)构成，PDB包含独立的系统表空间和SYSAUX表空间等，但是所有PDB共享CDB的控制文件、日志文件和UNDO表空间。各个PDB之间互访需要通过DB Link进行，就仿佛是多个数据库一样。
在2012 OOW上，Larry重点介绍了Oracle Database 12c 的这个新特性，并将其归结为：多租户数据库。也就是说，在云平台上，不同租户可以在一个大的CDB数据库中运行，而彼此数据(PDB)与应用又完全隔离。显然这个特性对Oracle推出的数据库云平台必不可少。
ORACLE 12C中提出来CDB和PDB的概念,对于ORACLE的数据库来说,确实是一个新东西,他们可以分别理解为容器和插件(PDB插入在CDB中),CDB的管理和传统数据库区别不大,本篇文章对PDB的部分操作进行了简单说明(创建PDB,OPEN PDB,DROP PDB,Plug PDB,Unplugging PDB)

http://www.xifenfei.com/4482.html
其实一句话，在原来Oracle12c之前版本的环境下，一个Oracle实例下，就可以创建相关的数据库，这个数据库就是在一个Oracle实例下的全局，该实例共享Oracle的系统文件、控制文件等，那么在Oracle12c环境下，在一个Oracle实例下，有一个全局库，全局库有可以管理可创建的可组装库，那么ArcSDE地理数据库就是一个组装库，问题的原因是用户应该创建Oracle12c的组装库。

那么接下来就看一下怎么创建？
查看一下Oracle的监听状态

The command completed successfully可以看到监听只对全局环境变量Orcl进行监听，并没有体现对组装库的监听
连接Sqlplus查看PDB

那么接下来，我们已经弄清楚出现问题的原因之后，我们重新输入参数信息，创建ArcSDE地理数据库
执行之后，我们看到ArcSDE地理数据库已经创建完成
我们导入数据进行测试
后续还会推出更多Oracle 12c新特性与ArcGIS数据结合的文章，尽情期待!
