Oracle Fusion Middleware定义：

什么是Oracle Fusion Middleware

Oracle Fusion Middleware is a comprehensive family of products ranging from application development tools and integration solutions to identity management, collaboration, and business intelligence reporting.

Oracle Fusion Middleware is a collection of standards-based software products that spans a range of tools and services: from Java EE and developer tools, to integration services, business intelligence, and collaboration. Oracle Fusion Middleware offers complete support for development, deployment, and management.

以上是Oracle的官方定义，从定义可以看出以下几点：

Oracle将Oracle Fusion Middleware定义为一个产品大家族
Oracle Fusion Middleware中涵盖的软件产品是基于标准的
从不水平角度来看，其涵盖了开发工具、整合方案、身份管理、协作、甚至是商业智能各领域的软件产品
从垂直角度来看，其提供了对开发、部署、管理的完整支持

Oracle Fusion Middleware中包含哪些组件

Oracle WebLogic Server：企业级Java应用服务器
Oracle SOA Suite：用于实现SOA的一系列软件
Oracle WebCenter：用于实现E2.0的一系列软件，也是Oracle现在主流的门户产品
Oracle HTTP Server：Web服务器
Oracle Web Cache：Web缓存服务
Oracle Identity Management：身份管理
Oracle Internet Directory：LDAP目录服务
Oracle Virtual Directory：虚拟目录服务（也就在异质的目录服务前端建立虚拟）
Oracle Identity Federation：联邦身份认证
Oracle Web Services Manager：Web Service安全
Oracle Platform Security：安全基础平台，这并不是一个产品，而是WebLogic Server安全框架与ADF安全的融合体
Oracle Portal：Oracle：Oracle以前的门户产品，现在主要服务于E-Business套件
Oracle Business Intelligence：商务智能，即：BI

Oracle Fusion Middleware组件分类

Oracle Fusion Middleware提供两类组件：Java组件与系统组件

Java组件（Java Components）

which is an Oracle Fusion Middleware component that is deployed as one or more Java EE applications and a set of resources. Java components are deployed to an Oracle WebLogic Server domain as part of a domain template. Examples of Java components are the Oracle SOA Suite and Oracle WebCenter components.

从定义中可以看出被归为Java组件的软件产品的显著特点是以WebLogic Server域模板的形式被部署到WebLogic Server之上。

系统组件（System Components）

which is a manageable process that is not deployed as a Java application. Instead, a system component is managed by the Oracle Process Manager and Notification (OPMN).

从定义看出可以看出被归为系统组件的软件产品的显著特点是不可以被当作Java应用部署，并且被OPMN管理.

什么是Oracle WebLogic Domain

Oracle WebLogic Domain是逻辑管理单元，基中包含一个管理服务器（Administration Server）及零个或多个被管理服务器（Managed Servers）。管理服务器与被管理服务器可以分布在不同的物理服务器上（可以不同CPU或操作系统）。多个被管理服务器可以被划分为一个集群。Web应用、EJB、WebServices等Java组件可以部署到管理服务器或被管理服务器或服务器集群中。

什么是Oracle Instance

每个Oracle Instance包含一个或多个系统组件，例如：Oracle WebCache，Oracle Cache，Oracle HTTP Server或 Oracle Internet Directory。一个Oracle Instance中的系统组件必须位于同一台物理机器。一个Oracle Instance目录包含：可更新文件，如：配置文件、日志文件或临时文件。

每个Oracle Instance与一个 Oracle WebLogic Server domain相配对。通常Oracle Instance目录可位于任何目录，但一般不位于Oracle Home目录内。

什么是Middleware Home

Middleware Home是一个容器，其中包含WebLogic Server Home，可选包括一个Oracle Common Home与一个或多个Orache Homes，其实Middleware Home就是过去的BEA Home。

什么是WebLogic Server Home

WebLogic Server Home包含WebLogic Server所必需的安装文件，WebLogic Server Home目录与Oracle Home目录是对等的，并且都位于Middleware Home。

什么是Oracle Home与Oracle Common Home

每个Orache Home包含组件或软件套件。例如：SOA Oracle Home是Oracle SOA Suite的安装目录。每个Oracle Home关联一个或多个Oracle 实例或Oracle WebLogic Server域。

每个Fusion Middleware Home只能包含一个Oracle Common Home，其中包含Oracle Enterprise Manager Fusion Middleware Control所需的二进制文件与类库和Java Required Files (JRF)

oracle怎么查询所有索引May 13, 2022 pm 05:23 PM

方法：1、利用“select*from user_indexes where table_name=表名”语句查询表中索引；2、利用“select*from all_indexes where table_name=表名”语句查询所有索引。

什么是oracle asmApr 18, 2022 pm 04:16 PM

oracle asm指的是“自动存储管理”，是一种卷管理器，可自动管理磁盘组并提供有效的数据冗余功能；它是做为单独的Oracle实例实施和部署。asm的优势：1、配置简单、可最大化推动数据库合并的存储资源利用；2、支持BIGFILE文件等。

oracle全角怎么转半角May 13, 2022 pm 03:21 PM

在oracle中，可以利用“TO_SINGLE_BYTE(String)”将全角转换为半角；“TO_SINGLE_BYTE”函数可以将参数中所有多字节字符都替换为等价的单字节字符，只有当数据库字符集同时包含多字节和单字节字符的时候有效。

Oracle怎么查询端口号May 13, 2022 am 10:10 AM

在Oracle中，可利用lsnrctl命令查询端口号，该命令是Oracle的监听命令；在启动、关闭或重启oracle监听器之前可使用该命令检查oracle监听器的状态，语法为“lsnrctl status”，结果PORT后的内容就是端口号。

oracle怎么删除sequenceMay 13, 2022 pm 03:35 PM

在oracle中，可以利用“drop sequence sequence名”来删除sequence；sequence是自动增加数字序列的意思，也就是序列号，序列号自动增加不能重置，因此需要利用drop sequence语句来删除序列。

oracle怎么查询数据类型May 13, 2022 pm 04:19 PM

在oracle中，可以利用“select ... From all_tab_columns where table_name=upper('表名') AND owner=upper('数据库登录用户名');”语句查询数据库表的数据类型。

oracle查询怎么不区分大小写May 10, 2022 pm 05:45 PM

方法：1、利用“LOWER(字段值)”将字段转为小写，或者利用“UPPER(字段值)”将字段转为大写；2、利用“REGEXP_LIKE(字符串,正则表达式,'i')”，当参数设置为“i”时，说明进行匹配不区分大小写。

Oracle怎么修改sessionMay 13, 2022 pm 05:06 PM

方法：1、利用“alter system set sessions=修改后的数值 scope=spfile”语句修改session参数；2、修改参数之后利用“shutdown immediate – startup”语句重启服务器即可生效。
