在開始之前，先介紹下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年開始，Oracle已經開始這一款產品的開發，現在已升級到5.0。細心的人估計以前注意到，Oracle11g中自帶了APEX開頭的賬戶，它們是APEX內建schema, 並且已經繫結到Oracle安裝中。也就是說，在你買了Oracle資料庫情況下，不要額外的License,就可以放心使用APEX。

出了免費外，它的優勢很明顯，

1，一切基於web, 架構在Oracle 資料庫上， 獨立於軟硬體環境

2，快速開發，極大縮短開發週期，支援html,css, javascript

2，相比OBIEE，SAPBO這樣重量級BI報表工具，它更加靈活，可以作為輕量級的BI解決方案

說了那麼多廢話，開始幹正事，準備安裝！

1，建立資料庫環境， 建立兩個表空間， 用於安裝APEX， 以便日後的管理。

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，下載解壓APEX 安裝包， 具體下載地址

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

3， 解壓完後， 切換到解壓後的目錄，並以sys登陸資料庫。 這一步目錄切換很重要，在APEX安裝過程中， 路徑用的是相對路徑，如果開始沒切換目錄的話， 過程中， 會報檔案找不到的錯誤

4， 安裝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/.

      我採用的是開發環境的安裝， 當然，在產品環境，可以選擇Runtime environment 模式安裝， sql 指令碼換成 @apxrtins.sql

      之前建立的兩個表空間將tablespace_apex, tablespace_files 替換如下： 

                      @apexins.sqlAPEX APEX_FILES TEMP /i/

     

這一步會花一段時間安裝完如果一切安裝順利的話， 就會出現和截圖一樣

當安裝完後， 一下三個schema 會被建立，有空的話，可以檢視驗證下

■ 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， 執行apxchpwd.sql,  它的作用如下， 就是設定APEX的超級管理員。 執行完後， 重啟資料庫。

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，   設定APEX_PUBLIC_USER, 為了下面配置ORDS 用

解鎖

SQL>ALTER USER APEX_PUBLIC_USER ACCOUNT UNLOCK

重置密碼

SQL>alter user apex_public_user identified by apex_public_user

7， 安裝配置Oracle Rest Data Services(ORDS)

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

      下載完後， 解壓指定好的安裝目錄。 解壓完後， 你可以發現ORDS這個就是個war包

   7.1 Disabling Oracle XML DB Protocol Server

SQL>EXEC DBMS_XDB.SETHTTPPORT(0);

SQL>

    7.2  configure RESTful Services in Oracle Application Express

           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， 這一步是賦連線的許可權給web 主機， 使它能能夠與ORDS進行連線

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;

      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

重啟tomcat，大功告成！

倒騰了這麼久，　給大家展示下介面，以及它的一個示例應用。　真心推薦大家研究並使用這個工具，很不錯～
