Oracle APEX installation with ORDS

标签：

在开始之前，先介绍下Oracle Application Express（APEX）。

Oracle Application Express—APEX for short, or by its former name HTML DB — is a declarative, Web-based RAD (Rapid Application development) tool. It is used to develop native Web-based, data centric applications. It requires no software to install on the client.

自2004年开始，Oracle已经开始这一款产品的开发，现在已升级到5.0。细心的人估计以前注意到，Oracle11g中自带了APEX开头的账户，它们是APEX内置schema, 并且已经绑定到Oracle安装中。也就是说，在你买了Oracle数据库情况下，不要额外的License,就可以放心使用APEX。

出了免费外，它的优势很明显，

1，一切基于web, 架构在Oracle 数据库上， 独立于软硬件环境

2，快速开发，极大缩短开发周期，支持html,css, javascript

2，相比OBIEE，SAPBO这样重量级BI报表工具，它更加灵活，可以作为轻量级的BI解决方案

至于我为甚用APEX，一句话领导不给力，不想买主流的 还让我们自己找免费的开发工具做报表，还要专业。擦，想让马儿跑，还不给喂草><||

还好，在以前的公司，接触过着APEX，当时还是版本3。虽然当时只是略懂皮毛，这回在选工具方面给了极大的帮助。 接下来，几个月，开始了死磕APEX的苦逼日子。

说了那么多废话，开始干正事，准备安装！

1，建立数据库环境， 创建两个表空间， 用于安装APEX， 以便日后的管理。

CREATE TABLESPACE APEX datafile‘/u01/app/oracle/oradata/APEX/apex.dbf’

SIZE 500M

EXTENT MANAGEMENT LOCAL

SEGMENT SPACE MANAGEMENT AUTO;

CREATE TABLESPACE APEX_FILES datafile‘/u01/app/oracle/oradata/APEX/apex_files.dbf’

SIZE 500M

EXTENT MANAGEMENT LOCAL

SEGMENT SPACE MANAGEMENT AUTO;

2，下载解压APEX 安装包， 具体下载地址

http://www.oracle.com/technetwork/developer-tools/apex/overview/index.html

3， 解压完后， 切换到解压后的目录，并以sys登陆数据库。 这一步目录切换很重要，在APEX安装过程中， 路径用的是相对路径，如果开始没切换目录的话， 过程中， 会报文件找不到的错误

4， 安装APEX, 命令如下

Full development environment. Run apexins.sql passingthe following four arguments in the order shown:

@apexins.sqltablespace_apex tablespace_files tablespace_tempimages

Where:

• tablespace_apex is the name of the tablespace for the Oracle Application Express application user.

• tablespace_files is the name of the tablespace for the Oracle Application Express files user.
• tablespace_temp is the name of the temporary tablespace or tablespace group.
• images is the virtual directory for Oracle Application Express images. To support future Oracle Application Express upgrades, define the virtual image directory as /i/.

      我采用的是开发环境的安装， 当然，在产品环境，可以选择Runtime environment 模式安装， sql 脚本换成 @apxrtins.sql

      之前创建的两个表空间将tablespace_apex, tablespace_files 替换如下： 

                      @apexins.sqlAPEX APEX_FILES TEMP /i/

这一步会花一段时间安装完如果一切安装顺利的话， 就会出现和截图一样

当安装完后， 一下三个schema 会被创建，有空的话，可以查看验证下

■ APEX_050000 - The account that owns the Oracle Application Express schema and
metadata.
■ FLOWS_FILES - The account that owns the Oracle Application Express uploaded
files.
■ APEX_PUBLIC_USER - The minimally privileged account is used for Oracle
Application Express configuration with Oracle REST Data Services or Oracle
HTTP Server and mod_plsql.

5， 运行apxchpwd.sql,  它的作用如下， 就是设置APEX的超级管理员。 运行完后， 重启数据库。

Running the apxchpwd.sql script enables your to create or update your Instance
Administrator account. You must run the apxchpwd.sql script in the following
scenarios:
■ New Oracle Application Express installations - Run apxchpwd.sql to create an
Instance Administrator account and password.
■ Converting of a runtime environment to a development environment - Run
apxchpwd.sql to change the Instance Administrator account password.
■ Changing Your Instance Administrator Password -Run apxchpwd.sql to change
the password for an existing Instance Administrator account.
■ Unlocking Your Instance Administrator Account - Run apxchpwd.sql to unlock
an existing Instance Administrator account.

  6，   设置APEX_PUBLIC_USER, 为了下面配置ORDS 用

解锁

SQL>ALTER USER APEX_PUBLIC_USER ACCOUNT UNLOCK

重置密码

SQL>alter user apex_public_user identified by apex_public_user

7， 安装配置Oracle Rest Data Services(ORDS)

     下载地址：http://www.oracle.com/technetwork/developer-tools/rest-data-services/downloads/
index.html

      下载完后， 解压指定好的安装目录。 解压完后， 你可以发现ORDS这个就是个war包

   7.1 Disabling Oracle XML DB Protocol Server

SQL>EXEC DBMS_XDB.SETHTTPPORT(0);

SQL>

           SQL>@apex_rest_config.sql

When configuring RESTful Services in OracleApplication Express, it creates two

new database accounts.

■ APEX_LISTENER - The account used to query RESTfulServices definitions

stored in Oracle Application Express.

■ APEX_REST_PUBLIC_USER - The account used whencalling RESTful Services

definitions stored in Oracle Application Express.

SQL>@apex_rest_config.sql 

Entera password for the APEX_LISTENER user              []

Entera password for the APEX_REST_PUBLIC_USER user              []

...createAPEX_LISTENER user

...createAPEX_REST_PUBLIC_USER user

SQL>

SQL>

     7.3 Granting Connect Privileges， 这一步是赋连接的权限给web 主机， 使它能能够与ORDS进行连接

SQL>

SQL>DECLARE

  2 ACL_PATH VARCHAR2(4000);

  3 BEGIN

  4  --Look for the ACL currently assigned to ‘*‘ and give APEX_050000

  5  --the "connect" privilege if APEX_050000 does not have the privilegeyet.

  6 SELECT ACL INTO ACL_PATH FROM DBA_NETWORK_ACLS

  7 WHERE HOST = ‘*‘ AND LOWER_PORT IS NULL AND UPPER_PORT IS NULL;

  8  IFDBMS_NETWORK_ACL_ADMIN.CHECK_PRIVILEGE(ACL_PATH, ‘APEX_050000‘,

  9 ‘connect‘) IS NULL THEN

 10 DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE(ACL_PATH,

 11 ‘APEX_050000‘, TRUE, ‘connect‘);

 12  ENDIF;

 13 EXCEPTION

 14  --When no ACL has been assigned to ‘*‘.

 15  WHENNO_DATA_FOUND THEN

 16 DBMS_NETWORK_ACL_ADMIN.CREATE_ACL(‘power_users.xml‘,

 17  ‘ACLthat lets power users to connect to everywhere‘,

 18 ‘APEX_050000‘, TRUE, ‘connect‘);

 19 DBMS_NETWORK_ACL_ADMIN.ASSIGN_ACL(‘power_users.xml‘,‘*‘);

 20  END;

 21  /

COMMIT;

SQL>SQL> 

      7.3 Configuring Oracle Application Express Images

Copy the contents ofthe <apex directory>/images folder to <Tomcatdirectory>/webapps/i/.

Where:

–<apexdirectory> is the directory location of the Oracle Application Expressdistribution.

–<Tomcatdirectory> is the folder where Apache Tomcat is installed.

    7.4 Configuring Oracle REST Data Services
         

  a,  copyords.war from ordspackage to tomcat webapps directory.

      b, configure REST DATA Services

           cd ../<tomcatdirecotory>/webapps

启用Tomcat，访问报错，已经检查过，apex那3个数据账号并没有问题。

查了好久，注意到了页面这一行字，此实例使用……, 与上面配置默认给的路径

INFO: Using configuration folder: /tmp/apex，并不是一个路径。

既然这样，只能指定一个路径专门放配置信息

[oracle@localhostwebapps]$ java -jar ords.war configdir

Jun 09, 201512:55:30 AM oracle.dbtools.common.config.cmds.ConfigDir execute

配置完路径后，重新配置ORDS

重启tomcat，大功告成！

倒腾了这么久，　给大家展示下界面，以及它的一个示例应用。　真心推荐大家研究并使用这个工具，很不错～
