•Configuring a client to access an Oracle database
Oracle Net provides support for the following methods: (Oracle Net提供了以下方法的支持:)
- Local naming: Uses a local configuration file (本地命名:使用本地配置文件)
- Directory naming: Uses a centralized LDAP-compliant directory server(目录命名:使用一个集中式的与ldap兼容的目录服务器)
- Easy connect naming: Uses a TCP/IP connect string (简单连接命名:使用一个/ip连接字符串)
- External naming: Uses a supported non-Oracle naming service (外部命名:使用受支持的非oracle命名服务)
2：创建和管理监听器
The server segment USES "netca" to configure orcle network monitoring(服务器段使用 “netca” 配置 orcle 网络监听)教程
1：在oracle 服务器端机器中；打开open terminal 后切换到oracle 用户 ；然后收入 “netcat”命令；如图
.
点击next 后选择新增
在上图输入 监听文字的信息后，点击next ，选择tcp 协议。然后再点击next
填入监听端口；默认为1521；填写完毕后，点击next
就这样一路默认下来基本就可以创建完成了
查看配置好的listen文件信息
1 [oracle@oracle admin]$ pwd 2 /u01/app/oracle/product/11.2.0/db_1/network/admin 3 [oracle@oracle admin]$ ls 4 listener17101810PM4639.bak listener.ora samples shrept.lst 5 [oracle@oracle admin]$ cat listener.ora 6 # listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora 7 # Generated by Oracle configuration tools. 8 9 LISTENER1 = 10 (DESCRIPTION_LIST = 11 (DESCRIPTION = 12 (ADDRESS = (PROTOCOL = TCP)(HOST = oracle.example.com)(PORT = 1522)) 13 ) 14 ) 15 16 ADR_BASE_LISTENER1 = /u01/app/oracle 17 18 LISTENER = 19 (DESCRIPTION_LIST = 20 (DESCRIPTION = 21 (ADDRESS = (PROTOCOL = TCP)(HOST = oracle.example.com)(PORT = 1521)) 22 (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) 23 ) 24 ) 25 26 ADR_BASE_LISTENER = /u01/app/oracle 27 28 [oracle@oracle admin]$ 29
The server segment USES "netmgr" to configure orcle network monitoring(服务器段使用 “netmgr” 配置 orcle 网络监听)教程
1: 使用 netmgr 启动 管理器
2：查看已经设置好的监听信息
给该监听增加新的监听方式信息：
增加新的监听内容：
接下来就是增加一些监听具体的监听方式：
最后关闭时，保存好设置好的设置信息：
以下是查看设置好的监听配置信息：
1 [oracle@oracle admin]$ pwd 2 /u01/app/oracle/product/11.2.0/db_1/network/admin 3 [oracle@oracle admin]$ ls 4 listener.ora samples shrept.lst 5 [oracle@oracle admin]$ cat listener.ora 6 # listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora 7 # Generated by Oracle configuration tools. 8 9 LISTENER1 = 10 (DESCRIPTION = 11 (ADDRESS = (PROTOCOL = TCP)(HOST = oracle.example.com)(PORT = 1522)) 12 ) 13 14 ADR_BASE_LISTENER1 = /u01/app/oracle 15 16 LISTENER = 17 (DESCRIPTION_LIST = 18 (DESCRIPTION = 19 (ADDRESS = (PROTOCOL = TCP)(HOST = oracle.example.com)(PORT = 1521)) 20 ) 21 (DESCRIPTION = 22 (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) 23 ) 24 ) 25 26 ADR_BASE_LISTENER = /u01/app/oracle 27 28 [oracle@oracle admin]$ 29使用 “netmgr” 创建 服务名
1：填写服务名：
选择tcp/ip 协议
填写主机名和端口号：
此测试告诉我的意思是：网络是通的，只是登录密码不对。可以关闭测试界面了
查看服务的配置信息

使用 netmgr 命令进行 监听注册监听信息
１：基本的创建请参考“上述：《使用 “netmgr” 创建 服务名》的操作步骤”
２：添加 静态注册监听信息
２－１：先创建１个 监听 LISTENER2
2-2:选择“数据库设置”
说明：Ｇlobal Database Name 一般都是在使用DBCA 静默方式安装数据实例或者是 使用手动建库方式创建数据库实例时都需要配置的数据库域名；
即：这个数据库系统参数的值： db_domain='prod2’ ;一般情况该值的输入都是一个域名的模式：db_domain='PROD2.orcle.com' ；
此处因为我在使用手工建库的时候是没有写该系统参数，于是创建数据库实例的时候是取的默认缺省值。
在dbca图鉴命令创建的时候填写的位置为：
Ｏracle Home Directory : oracle数据库默认安装路径：/u01/app/oracle/product/11.2.0/db_1
ＳID: 数据库实例SID: prod2
二：配置 Oracle 网络环境
1：网络故障 failover
2：设置网络追踪
3：配置数据库实例支持共享服务
共享Server：也就是多个人共享１个空闲Ｓerver process;
.分发器（dispatcher）:处理连接数太多的情况进行分发连接。
目的就是为了节约服务器内存。
具体的Oracle数据库结构内容请 参考《Oracle 服务器结构》中的第二点内容：
1 ---------程序全局区 (PGA) 2 程序全局区 (PGA) 是包含某服务器进程的数据及控制信息的内存区。 3 这是 Oracle 服务器在服务器进程启动时创建的非共享内存，只有该服务器进程才能访问。 4 Oracle 实例的所有服务器进程分配的 PGA 总内存，也称为该实例分配的聚集 PGA 内存。 5 使用共享服务器时，部分 PGA 可位于 SGA 中。 6 7 PGA 内存通常包含以下各项： 8 专用 SQL 区 、游标和 SQL 区、工作区、会话内存 9 10 专用 SQL 区 11 专用 SQL 区包含绑定信息和运行时内存结构等数据。这些信息是每个会话的 SQL 语句调用所特有的；在其它方面，绑定变量有不同的值，游标的状态也不同。发出 SQL 语句的每个会话都有一个专用 SQL 区。提交同一 SQL 语句的每个用户也都有其自己的专用 SQL区，该专用 SQL 区使用一个共享 SQL 区。这样，许多专用 SQL 区可与同一个共享 SQL区关联。专用 SQL 区的位置取决于为会话建立的连接类型。 12 13 如果会话是通过专用服务器连接的，则专用 SQL 区位于该服务器进程的 PGA 中。 14 不过，如果会话是通过共享服务器连接的，则部分专用 SQL 区将保留在 SGA 中。 15 16 17 游标和 SQL 区 18 Oracle 预编译器程序或 OCI 程序的应用程序开发人员可以显式打开特定专用 SQL 区的游标或句柄，并在该程序的整个执行过程中将它们用作命名资源。数据库为某些 SQL 语句隐式发出的递归游标也使用共享 SQL 区。 19 20 21 工作作区 22 对于复杂查询（例如，决策支持查询），会将大部分 PGA 供内存密集型运算符分配的 23 工作区专用，例如： 24 基于排序的运算符（如 ORDER BY、GROUP BY、ROLLUP）和窗口函数 25 散列联接 26 位图合并 27 位图创建 28 批量装载操作使用的写缓冲区 29 排序运算符使用工作区（排序区），对一组行执行内存中排序。与此类似，散列联接运算 30 符使用工作区（散列区），根据其左侧输入内容生成散列表。 31 32 工作区的大小是可以控制和优化的。通常，较大的工作区可以显著改进特定运算符的性能，不过代价是消耗较多的内存。 33 34 35 会话内存 36 会话内存是用于存放会话的变量（登录信息）以及与会话相关的其它信息的内存。对于共享服务器，会话内存是共享的，而不是专用的。 37 38 39 ----------自动 PGA 内存管理 40 根据 PGA_AGGREGATE_TARGET 参数，动态调整 41 专用于工作区的 PGA 内存量 42 有助于最大限度地提高所有内存密集型 SQL 操作的性能 43 默认情况下是启用的 44 45 46 理想情况下，工作区的大小只要能容纳其相关 SQL 运算符分配的输入数据和辅助内存结构就已足够。这一大小称为工作区的最佳大小。工作区大小小于最佳大小时，响应时间就会增加，因为要对部分输入数据执行额外的传输操作。 47 48 49 自动 PGA 内存管理功能简化并改进了 PGA 内存的分配方式。默认情况下，PGA 内存管理功能是启用的。在此模式下，Oracle 数据库以 SGA 内存大小的 20% 为基准，动态调整 50 专用于工作区的那部分 PGA 内存的大小。最小值为 10 MB。 51 52 53 在自动 PGA 内存管理模式下运行时，所有会话的工作区大小的调整都是自动的， 54 55 在任何给定时间，可用于实例中各活动工作区的 PGA 内存总量自动从 56 PGA_AGGREGATE_TARGET 初始化参数派生。此内存量设置为 57 PGA_AGGREGATE_TARGET 值减去系统其它组件分配的 PGA 内存量（例如，会话分配的 58 PGA 内存）。由此得到的 PGA 内存随后按照各活动工作区的特定内存需求分配给相应的工作区。 59 60 61 --PGA 管理资源 62 配置新实例时，难以确切知道 PGA_AGGREGATE_TARGET 的适当设置。该设置可以通过 63 以下三个阶段确定： 64 1.根据惯例，初步估算 PGA_AGGREGATE_TARGET。默认情况下，Oracle DB 将其设 65 置为 SGA 大小的 20%。不过，对于大型 DSS 系统而言，此初始设置可能太低。 66 2.在实例上运行典型工作量，使用 Oracle 收集到的 PGA 统计信息监视性能，查看最大 PGA 大小的配置是过低还是过高。 67 3.使用 Oracle PGA 建议统计信息来优化 PGA_AGGREGATE_TARGET。 68 69 70 为了能够向后兼容，可以通过将 PGA_AGGREGATE_TARGET 初始化参数值设置为 0， 71 来禁用自动 PGA 内存管理。禁用了自动 PGA 内存管理功能后，可以使用关联的 72 *_AREA_SIZE 参数调整工作区的最大大小。以下是这些参数的示例： 73 74 SORT_AREA_SIZE 75 HASH_AREA_SIZE 76 BITMAP_MERGE_AREA_SIZE 77 CREATE_BITMAP_AREA_SIZE 78 79 80 ---------------使用内存指导调整 SGA 的大小 81 使用内存指导可以优化内存结构的大小。如果启用了自动管理共享内存功能，则可以使 82 用该功能优化 SGA 的总大小。如果禁用了 ASMM，则可以使用此指导来优化 SGA 的不同组件。 83 84 内存指导包括三个指导： 85 共享池 86 缓冲区高速缓存 87 主页---相关链接---指导中心----内存指导----共享池或缓冲区高速缓存--建议 88 89 90 91 使用内存指导调整 PGA 的大小 92 可使用内存指导获取有关 PGA 大小的建议。单击“PGA”选项卡，然后单击 93 “Advice（建议）”。 94

#使用dbca创建一个PROD1数据库，包括Sample Schema，启用archivelog，没有EM。
1.1 Create a PROD1 database with dbca, including Sample Schema, enable archivelog, without EM.
#全局数据库名称：PROD1.oracle.com ; SID：PROD1
Global db name: PROD1.oracle.com SID: PROD1
1) Login as Linux user "oracle" ；即 从 root 用户登录到oracle 用户，并核查oracle 用户下关于oracle数据库的系统环境参数信息
1 #切换oracle用户 2 [root@oracle ~]# su - oracle 3 #查看本用户根目录下信息 4 [oracle@oracle ~]$ ls -a 5 . .. .bash_history .bash_logout .bash_profile .bashrc .emacs .kde .mozilla .viminfo .zshrc 6 #查看 .bash_profile 信息：在不同机器上面，该值名称不一定一样 7 [oracle@oracle ~]$ cat .bash_profile 8 # .bash_profile 9 10 # Get the aliases and functions 11 if [ -f ~/.bashrc ]; then 12 . ~/.bashrc 13 fi 14 15 # User specific environment and startup programs 16 17 PATH=$PATH:$HOME/bin 18 19 export PATH 20 export ORACLE_SID=PROD1 21 export ORACLE_BASE=/u01/app/oracle 22 export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1 23 export PATH=$PATH:$ORACLE_HOME/bin 24 25 export ORACLE_TERM=xterm 26 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib 27 28 export CLASSPATH=$ORACLE_HOME/JRE:ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib 29 30 [oracle@oracle ~]$ 312) Run the cmd of Database Configuration Assistant 执行DBCA 命令：
命令执行之前，需要用root用户执行 xhost + 命令
1 [root@oracle ~]# xhost + 2 access control disabled, clients can connect from any host 3 [root@oracle ~]# 4执行DBCA命令
1 [oracle@oracle ~]$ dbca 23) Welcome screen -> Click "Next" 命令执行后，调用出图形界面：执行下一步操作
4) Select "Create database" -> Click "Next" 选择创建数据库，然后在执行下一步按钮
5) Select "Custom Database" -> Click "Next" 此处按照要求选择相对应选项。此处我选择的是 第一个选项

SID = "PROD1"
Click "Next"
7) Deselect "Configure Enterprise Manager" -> Click "Next" ；去掉“配置企业管理器”的选择
注意：如果选择此项，需要先启动监听(Listener)
8) Select "Use the Same Administrative Password for All Account"
Password = "xxxxxx" (例如：oracle)
Confirm Password = "xxxxxx" (例如：oracle)
Click "Next"把所有用户的密码都设置一样的选择。 考试的时候最后都设置一样的 除掉默认的oracle 名称其他的密码；
password entered does not satisty oracle recommended password complexity policy.
a password should hava minimum of 8 characters in length . in addition,the password must contain at least one upper case character ,one lower case character and one digit;密码输入不符合oracle推荐的密码复杂性策略。 一个密码最多不得超过8个字符。 此外，密码必须包含至少一个大写字母，一个小写字母和一位数字;
9) Set the storage type: 设置存储类型：
Storage Type = "File System" 存储类型=“文件系统”
Select "Use Common Location for All Database Files" 选择“对所有数据库文件使用通用位置”
Database Files Location = "{ORACLE_BASE}/oradata" 数据库文件位置=“{ORACLE_BASE} / oradata”
Click "Next"
10) Keep the default settings of Flash/Fast Recovery Area -> Deselect "Enable Archiving" -> Click "Next"
保留Flash（闪存） /快速恢复区域的默认设置 - >取消选择“启用归档” - >单击“下一步”
11) Select "Sample Schema" and keep the default settings of other components -> Click "Next"
选择安装默认组件：完成时间？
取消安装全部组件：完成时间？
12) Select the character set, keep other options by default
