تأسيس الاتصال

بسم الله و الحمدلله و الصلاة والسلام على رسول الله:

لتأسيس  الاتصال بين السيرفر و بقية الحواسيب نحتاج إلى التالي :






--------------

Listener Configuration:
C:\Program Files\Java\jre6\bin\java -Dapex.erase -Dapex.port=3142 -Dapex.home=C:\Connection -Dapex.images=C:\apex\images -jar C:\Connection\apex.war
--------------
Start up file:
"C:\Program Files\Java\jre6\bin\java" -Dapex.erase -Dapex.port=3142 -Dapex.home=C:\Connection -Dapex.images=C:\apex\images -jar C:\Connection\apex.war  >>C:\Connection\my_apex_listener.log 2>&1
--------------
Unlock APEX_PUBLIC_USER:

CONNECT TO SQLPLUS as sysdba
then type:
alter user apex_public_user account unlock
alter user apex_public_user identified by oracle
--------------
Change HTTP Port:
أولا تأكد من رقم البورت


select dbms_xdb.gethttpport as "HTTP-Port"
            , dbms_xdb.getftpport as "FTP-Port" from dual;
لتغير رقم البورت 

 
begin
   dbms_xdb.sethttpport('هنا ضع رقم البورت الذي تريد');
   dbms_xdb.setftpport('هنا ضع رقم البورت الذي تريد');
  end;

 3142 إذا كنت ترغب في تغير رقم البورت المستخدم للاتصال بالسيرفر, فعليك تغير الرقم  
في 
Startup file and listener configuration 


الحمدلله و الصلاة والسلام على رسول الله.
السلام عليكم و رحمة الله وبركاته

تصدير تطبيق 2 , إنشاء أغراض قواعد البيانات




بسم الله و الحمد لله و الصلاة و السلام عل رسول الله
السلام عليكم و رحمة الله و بركاته,  من أجل أن تكون الأمور واضحة سنقوم في هذه المحاضرة بإنشاء :
Tables , Sequences, Triggers.
و سنرى إن شاء الله تعالى كيفك يتم توليد الكود لهذه الأغراض . أقصد
Generate DDL : Data Dentition Language 
على أي حال حفاظأ على قتك . ربما تستطيع مشاهدة هذه المحاضرة و أنت تتناول الغداء فهي لا تحتاج إلى تركيز...  إلا إذا كنت مبتدأ
علما أنني عمدا قمت بإنشاء الجداول أولا ثم إضافة القيود .....
ثم في المحاضرة التالية سنبيني التطبيق بالاعتماد على هذه الأغراض:  إن شاء الله تعالى


إنشاء جداول الموظفين و الأقسام:

CREATE TABLE  EMP2
   (
EMPNO NUMBER(4,0) ,
ENAME VARCHAR2(10),
JOB VARCHAR2(9),
MGR NUMBER(4,0),
HIREDATE DATE,
SAL NUMBER(7,2),
COMM NUMBER(7,2),
DEPTNO NUMBER(2,0)
);
-------

CREATE TABLE  DEPT2
(
DEPTNO NUMBER(2,0),
DNAME VARCHAR2(14),
LOC VARCHAR2(13)
        );
-------------------------------------------------
إنشاء القيود

alter table emp2 add constraint PK_emp2 primary key (EMPNO);

-------



alter table dept2 add constraint PK_dept2 primary key (deptno);
-------



alter table emp2 add constraint FK_emp2 foreign key (DEPTNO) references DEPT2 (DEPTNO);

-------------------------------------------------


إنشاء المتسلسلات Sequences

create sequence emp2_seq;


-------



create sequence dept2_seq;

-------------------------------------------------
إنشاء القوادح Triggers



create or replace trigger BI_emp2
before insert on emp2
for each row
begin
if :new.empno is null then
select emp_seq2.nextval into :new.empno from dual;
end if;
end;

-------

alter trigger bi_emp enable;


-------

create or replace trigger BI_dept2


before insert on dept2
for each row
begin
if :new.DEPTNO is null then
select dept2_seq.nextval into :new.DEPTNO from dual;
end if;
end;

-------

alter trigger BI_dept2 enable;



-------------------------------------------------



إدخال البيانات: Inserting The Data

INSERT INTO EMP2 VALUES
(7369,'SMITH','CLERK',7902,to_date('17-12-1980','dd-mm-yyyy'),800,NULL,20);
INSERT INTO EMP2 VALUES
(7499,'ALLEN','SALESMAN',7698,to_date('20-2-1981','dd-mm-yyyy'),1600,300,30);
INSERT INTO EMP2 VALUES
(7521,'WARD','SALESMAN',7698,to_date('22-2-1981','dd-mm-yyyy'),1250,500,30);
INSERT INTO EMP2 VALUES
(7566,'JONES','MANAGER',7839,to_date('2-4-1981','dd-mm-yyyy'),2975,NULL,20);
INSERT INTO EMP2 VALUES
(7654,'MARTIN','SALESMAN',7698,to_date('28-9-1981','dd-mm-yyyy'),1250,1400,30);
INSERT INTO EMP2 VALUES
(7698,'BLAKE','MANAGER',7839,to_date('1-5-1981','dd-mm-yyyy'),2850,NULL,30);
INSERT INTO EMP2 VALUES
(7782,'CLARK','MANAGER',7839,to_date('9-6-1981','dd-mm-yyyy'),2450,NULL,10);
INSERT INTO EMP2 VALUES
(7788,'SCOTT','ANALYST',7566,to_date('13-JUL-87')-85,3000,NULL,20);
INSERT INTO EMP2 VALUES
(7839,'KING','PRESIDENT',NULL,to_date('17-11-1981','dd-mm-yyyy'),5000,NULL,10);
INSERT INTO EMP2 VALUES
(7844,'TURNER','SALESMAN',7698,to_date('8-9-1981','dd-mm-yyyy'),1500,0,30);
INSERT INTO EMP2 VALUES
(7876,'ADAMS','CLERK',7788,to_date('13-JUL-87')-51,1100,NULL,20);
INSERT INTO EMP2 VALUES
(7900,'JAMES','CLERK',7698,to_date('3-12-1981','dd-mm-yyyy'),950,NULL,30);
INSERT INTO EMP2 VALUES
(7902,'FORD','ANALYST',7566,to_date('3-12-1981','dd-mm-yyyy'),3000,NULL,20);
INSERT INTO EMP2 VALUES
(7934,'MILLER','CLERK',7782,to_date('23-1-1982','dd-mm-yyyy'),1300,NULL,10);



-------



INSERT INTO DEPT2 VALUES
(10,'ACCOUNTING','NEW YORK');
INSERT INTO DEPT2 VALUES
                 (20,'RESEARCH','DALLAS');
INSERT INTO DEPT2 VALUES
(30,'SALES','CHICAGO');
INSERT INTO DEPT2 VALUES
(40,'OPERATIONS','BOSTON');




I hope that has been informative for you. Please do not hesitate to pose any question, and I will answer you as I have time بإذن الله تعالى

Oracle Application Express


Upgrading Oracle Application Express within Oracle 


Database 10g Express Edition (XE)

Oracle Database 10 g Express Edition (Oracle XE) includes Oracle Application Express release 2.1. It is strongly recommended that you upgrade to the latest release of Oracle Application Express to take advantage of all the latest features.



How to Upgrade

To install the latest version of Oracle Application Express in your Oracle Database XE, first download the latest version of Application Express from the Oracle Technology Network.
1. Unzip the downloadloaded zip file:
  • Linux: Unzip <filename>.zip
  • Windows: Double click <filename>.zip in Windows Explorer
  • [Note: You should keep the directory tree where you unzip the files short and not under directories that contain spaces. 
    For example, within Windows unzip to C:\.]
2. Change your working directory to apex.
3. Start SQL*Plus and connect to the Oracle XE database:
  • Linux:
    $ sqlplus /nolog
	SQL> CONNECT SYS as SYSDBA
	Enter Password:	
	SYS_Password
  • Windows:
    {Command prompt} C:\apex> sqlplus /nolog
	SQL> CONNECT SYS as SYSDBA
	Enter Password:	
	SYS_Password
  • [Note: You should keep the directory tree where you unzip the files short and not under directories that contain spaces. 
    For example, within Windows unzip to C:\.]
4. Install Application Express:
  • SQL> @apexins SYSAUX SYSAUX TEMP /i/
5. Log back into SQL*Plus (as above) and load images:
  • SQL> @apxldimg.sql APEX_HOME
  • [Note: APEX_HOME is the directory you specified when unzipping the file. For example, with Windows 'C:\'.]
6. Upgrade Application Express password:
  • SQL> @apxchpwd
Enter password for Application Express ADMIN account.
7. In a Web browser, navigate to the Oracle Application Express Administration Services application:
  • http://localhost:8080/apex/apex_admin
  • In Username, enter ADMIN
