在ORACLE 12C 上安装APEX 4.2

APEX基本上是基于MVC模式的，M是item，V是html，C是调用的程序包，下面演示了如何在12C上安装APEX，前提是在winddows上安装了ORACLE 12.1 数据库。 一般生产环境安装的中间件为Oracle的融合中间件weblogic，也用用OHS的，如果并发量不是很高的话。

1.检查是否满足安装条件

1.1 修改share_pool_size

SQL> show parameter pfile;

NAME                                 TYPE
------------------------------------ ---------------------------------
VALUE
------------------------------
spfile                               string
C:\APP\ORACLE\ORACLE\PRODUCT\1
2.1.0\DBHOME_1\DATABASE\SPFILE
ORCL.ORA

SQL> SHOW PARAMETER SHARED_POOL_SIZE

NAME                                 TYPE
------------------------------------ ---------------------------------
VALUE
------------------------------
shared_pool_size                     big integer
0
SQL>  ALTER SYSTEM SET SHARED_POOL_SIZE='100M' SCOPE=spfile;

System altered.

SQL> shutdown
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup
ORACLE instance started.

1.2 浏览器要求

■ Microsoft Internet Explorer 7.0 or later

■ Mozilla Firefox 14 or later

■ Google Chrome 21 or later

■ Apple Safari 5.0 or later

1.3 中间件要求

内嵌的pl/sql网关

OHS

Oracle REST Data Services

1.4 磁盘空间

这个有个1G就可以。

1.5 Oracle XML DB 必须安装

这个只要是用dbca建立的库都默认已经安装，检查方法：

2. 进入安装阶段

2.1 配置ORACLE_HOME

@apex_epg_config C:\app\oracle\oracle\product\12.1.0\dbhome_1

C:\app\oracle\oracle\product\12.1.0\dbhome_1\apex>sqlplus "/ as sysdba"

SQL> alter session set container = pdborcl;

--配置端口和管理员密码
SQL> @apxconf

PORT
----------
8080

Enter values below for the XDB HTTP listener port and the password for the Application Express ADMIN user.
Default values are in brackets [ ].
Press Enter to accept the default value.

Enter a value below for the password for the Application Express ADMIN user.

Enter a password for the ADMIN user              []

Session altered.

...changing password for ADMIN

PL/SQL procedure successfully completed.

Enter a port for the XDB HTTP listener [      8080]
...changing HTTP Port

PL/SQL procedure successfully completed.

2.2 配置网关和安全规则

解锁用户，pdb和cdb下的匿名用户都要解锁啊，因为cdb下的anonymous没有解锁，导致apex的静态页面出不来，只是一个中间件的验证窗口要求登录，看日志也没有看出个鸟来，最后检查发现是匿名用户没有解锁导致，官方文档的意思是pdb和cdb都有解锁：

SQL> ALTER SESSION SET CONTAINER = CDB$ROOT;

Session altered.

SQL> ALTER SESSION SET CONTAINER = CDB$ROOT;

Session altered.

SQL> ALTER USER ANONYMOUS ACCOUNT UNLOCK;

User altered.

SQL> commit
2  ;

Commit complete.

SQL> SELECT DBMS_XDB.GETHTTPPORT FROM DUAL;

GETHTTPPORT
-----------
0

SQL> alter session set container = pdborcl;

Session altered.

SQL> SELECT DBMS_XDB.GETHTTPPORT FROM DUAL;

GETHTTPPORT
-----------
8080

SQL> ALTER USER ANONYMOUS ACCOUNT UNLOCK;

User altered.

SQL> commit
2  ;

Commit complete.

SQL>

最大权限：

DECLARE
acl_path VARCHAR2(4000);
BEGIN
-- Look for the ACL currently assigned to '*' and give APEX_040200  -- the "connect" privilege if APEX_040200 does not have the privilege yet.
SELECT acl
INTO acl_path
FROM dba_network_acls
WHERE host = '*'
AND lower_port IS NULL
AND upper_port IS NULL;
IF dbms_network_acl_admin.check_privilege(acl_path,
'APEX_040200',
'connect') IS NULL THEN
dbms_network_acl_admin.add_privilege(acl_path,
'APEX_040200',
TRUE,
'connect');
END IF;
EXCEPTION
WHEN no_data_found THEN
dbms_network_acl_admin.create_acl('power_users.xml',
'ACL that lets power users to connect to everywhere',
'APEX_040200',
TRUE,
'connect');
dbms_network_acl_admin.assign_acl('power_users.xml', '*');
END;
/
commit;

此时登录http://localhost:8080/apex/apex_admin 已经可以访问了。

输入admin密码是初始配置时的密码

3.安装汉化包

进入到apex\builder\zh-cn

C:\app\oracle\oracle\product\12.1.0\dbhome_1\apex\builder\zh-cn>set NLS_LANG=American_America.AL32UTF8

C:\app\oracle\oracle\product\12.1.0\dbhome_1\apex\builder\zh-cn>sqlplus "/ as sysdba"

SQL*Plus: Release 12.1.0.2.0 Production on Wed Aug 17 01:01:06 2016

Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production

SQL> alter session set container = pdborcl;

Session altered.

SQL>ALTER SESSION SET CURRENT_SCHEMA = APEX_040200;

Session altered.

SQL> @load_zh-cn.sql

--然后进入了漫长的等待...一二十分钟后就可以汉化好了。

4. 配置作业数量JOB_QUEUE_PROCESSES、SHARED_SERVERS

SQL> SELECT VALUE FROM v$parameter WHERE NAME = 'job_queue_processes'
2  ;

VALUE
--------------------------------------------------------------------------------
1000

1 row selected.

SQL> show parameter shared

NAME                                 TYPE
------------------------------------ ---------------------------------
VALUE
------------------------------
hi_shared_memory_address             integer
0
max_shared_servers                   integer

shared_memory_address                integer
0
shared_pool_reserved_size            big integer
5872025
shared_pool_size                     big integer

NAME                                 TYPE
------------------------------------ ---------------------------------
VALUE
------------------------------
112M
shared_server_sessions               integer

shared_servers                       integer
1
SQL> ALTER SYSTEM SET SHARED_SERVERS = 5 SCOPE=BOTH;

System altered.

SQL> commit;
