Fixing Internet Explorer Crash on Launching Oracle Forms

here is simple video shows how to fix  Internet Explorer crash when running Forms.

replace jvm.dll file in the following path :

C:\Program Files (x86)\Oracle\JInitiator 1.3.1.22\bin\hotspot

you can download jvm file from here.

Using Aliases in same query

Alias is very helpful to shorten long query in SQL.



To use Alias in the same query you can use the following method:







SELECT  A,B,C*50 from (select A,B,(A+B) as C from table).



note that you can choose  any column from inner-query to display it in outer-query.



but you cannot display a column in outer-query which is not exist in inner-query.

You can try this example using SCOTT schema:



select  SAL,COMM,COMM_RATE *100 from (

select SAL,COMM,(COMM/SAL) as COMM_RATE from emp)

Remove the 'Do you want to save changes?' Messages in Forms

here is it ...

1. Modify the CLEAR_ALL_MASTER_DETAILS procedure body. Change the existing CLEAR_BLOCK(ASK_COMMIT) to CLEAR_BLOCK(DO_COMMIT).

2. Specifying NO_COMMIT or NO_VALIDATE with the CLEAR_BLOCK built-in causes

Oracle Forms to flush the current block without performing a commit or prompting the operator.

ex:CLEAR_BLOCK(NO_COMMIT,NO_VALIDATE);

Run Oracle forms from LAN

Assalamu Alikom,



I can not deny how does this work took time as I searched for it and made many tries between fails and success .



And here is the steps to run your Oracle project from any computer on the Local Network. 


Windows XP is recommened to install Application Server


1#Step : Install ORACLE DataBase 10g 




2#Step : Install ORACLE Developer 10g




After installation of Oracle developer :



goto C:\oracle\product\10.2.0\db_1\NETWORK\ADMIN

then copy the files : 



listener.ora



sqlnet.ora



tnsnames.ora



and paste them to the following path :



C:\DevSuiteHome_1\NETWORK\ADMIN

3#Step : Install Application Server



download it from here ...



Be very careful before install and follow steps below :



1-download file staticports.conf   from here... and copy it to path  C:\oracle\FRHome_1\

2-Choose Manual install then choose the file staticports.conf





3-After install finishes write down the link appears to access Oracle Enterprise Manager, it looks like (http://localhost:7798)



4-goto C:\oracle\product\10.2.0\db_1\NETWORK\ADMIN



then copy the files : 



listener.ora



sqlnet.ora



tnsnames.ora




and paste them to the following path :



C:\oracle\FRHome_1\NETWORK\ADMIN

5- Goto path C:\oracle\FRHome_1\\forms\server  where you installed app server

and make copy of file default.env  and paste it in the same place

6- Rename the new file to tr.env (you can rename it to any of yours)

7- Open file tr.env using  notepad

8-Edit the Form_path to FORMS_PATH=C:\DevsuiteHome_1\forms

Important: copy all your fmx  files of your project in the path (C:\FRHome_1\forms)

4#Step : Configure Application Server

1-Login Appserver  by typing Localhost in the address bar of any browser(internet explorer is preferred) or the link you wrote before

2-Choose Forms then  choose Configuration then choose Duplicate then choose New Section

and name it :EFL  (you can rename it to any of yours) then click OK

3-Choose Forms then  choose Configuration then select  EFL then click Edit

4- Edit the following items as followed:

baseHTMLjinitiator:basejini.htm

baseHTMLjpi:basejpi.htm

envFile:tr.env

form:login.fmx

userid:hr/hr@orcl

page Title:My First AppServer Application

then click Apply

5-Choose Forms  again and  copy the  link Servlet URL : http://localhost:7801/forms/frmservlt

6- edit the link to be http://localhost:7801/forms/frmservlt?config=EFL 

then paste it  in the browser and click Enter from keyboard

If you are on windows 7 then edit the baseHTMLjinitiator:basejpi.htm

6-Goto Oracle Enterprise Manager then choose PORTS  then select  WebCache     http

then click Edit icon

make it 80 then click OK  then it asks you Restart webcache? click Yes

be sure the Port:80 is not used by other programs on your PC

7-Open notepad then write the following code

You can get it from here :

https://drive.google.com/open?id=0B2PUacEN7OKGamgtTXluTmVFVTg


save file as rd.html

8- Paste rd.html  in the path C:\oracle\FRHome_1\Apache\Apache\htdocs

9-Goto Oracle Enterprise Manager then choose HTTP SERVER then Administration then Advanced server Properties  then  Httpd.conf

10- Search for DirectoryIndex then

make it DirectoryIndex rd.html

*OC4J  and Reports Server must be opened all time


5#Step : Running Forms over LAN

1-after running project on server   , we got the link like this:

http://localhost/forms/frmservlet?config=efl


2-replace localhost with server IP Address(you can get ip address  from Start then CMD then ipconfig then press enter)


it becomes 

http://192.168.1.4/forms/frmservlet?config=efl


3-From any computer connected to server over Local network  :

 install J initiator

goto   http://192.168.1.4/forms/frmservlet?config=efl


Update#1 : 

You can add multiple users with different Schemes by editing the file :

C:\oracle\FRHome_1\forms\server\formsweb.cfg 


you  just add in the end of file name , form path   and User credentials like  this :


[hr]

form=e:\hrm\Login.fmx



userid=hr/hr@orcl


Then the address to access this users forms is :

http://192.168.1.4/forms/frmservlet?config=hr


Update#2 : 

To display Arabic fonts  well , you must :


1#Replace uifont.ali  which is located in the following two paths :

C:\DevSuiteHome_1\tools\common

C:\oracle\FRHome_1\tools\common


2#Add Windows Fonts folder in Registry , It's found twice inside  Registry

MS Server 2008 R2 Sounds

In the previous blog we talked about enabling Wireless in Microsoft server 2008 , here is the way to  enable the SOUNDS too.

Article was pick from HowToGeek web site.

All it takes to get sound functionality out of Server 2008 R2 is to set the Windows Audio service to start up automatically. To do this we need to open the Services MMC, the quickest way to do this is to press the Win + R key combination to bring up a run box, type services.msc and hit enter.

Once the Snap-In opens scroll down until you find the Windows Audio Service.

Double-click on it to open its properties.

Now you need to change the Startup drop-down box from Manual to Automatic.

Click ok when you are done, and restart your computer.

You should notice that your volume control icon went from looking like this

To this

You can now play music and movies through Windows Media Player which was installed in the first part of the series, or you could install a third party media player.

MS SERVER 2008 wireless

You may need to install Windows Server 2008 R2  for some reasons like creating Oracle Application Server.

But you notice that WI-FI can not run  even if  drivers are installed so here is how to fix it.

This article is from Microsoft website.



At first, setting up a wireless connection on a system running Windows Server 2008 R2 seems pretty straightforward. Simply open the Network and Sharing Center, go to Change Adapter Settings, right-click on the wireless network controller, and select Enable. Now configure the network settings. 



However, you might notice that the wireless connection is still disabled. This is because the typical installation of Windows Server 2008 R2 is "locked down" with Roles and Features disabled by default. The fix is very easy, though, once you know the problem. 



To enable support for wireless networking:

• open Server Manager


• Select Features in the left pane


• Select Add Features


• Select the check box next to Wireless LAN Service


• Press the Install button to confirm your selection

After installation of the Wireless LAN Service feature is complete, you can go back to Network Connections and enable the wireless controller (if it didn’t already become enabled). And now you can right-click on the connection and select Connect/Disconnect and configure settings for the wireless network to which you want to connect.

التاريخ الهجري و الميلادي في اوراكل Gregorian & Hijri date in Oracle

السلام عليكم و رحمة الله 

هذه اول مواضيعي في مجموعة مستخدمي اوراكل العرب araboug اسال الله تعالى ان ينفعني و اياكم بها.

لا يخفى على احد اهمية استخدام التاريخ الهجري و لا يمكن الاعتماد كليه على معادلات اوراكل مثل :

-- لتحويل تاريخ اليوم الميلادي الى هجري  نستخدم

select to_char(sysdate,'dd/mm/yyyy','nls_calendar =''arabic hijrah''') from dual

حيث نجد اختلاف يوم او يومين فمثلا يوم 13 صفر 1437 

عند تحويله باستخدام المعادلة السابقة فالناتج يكون :

12/02/1438

و لكن الصحيح ان التاريخ الهجري المقابل للتاريخ الميلادي 13/11/2016 هو13/02/1438.

و افضل طريقة حسب ما اعرف و قرات هو الاحتفاظ بالتاريخ الهجري في قاعدة البيانات كما هو دون الاعتماد على معادلات اوراكل.

 الطريقة التي اعتمدت عليها :

 #  انشاء جدول 

Create table Ar_convert_date (convert_id number , Hj_date    varchar2(10) , G_date varchar2(10))

# عمل شيت اكسيل بنفس شكل الجدول و يبدا التاريخ الميلادي من 01/01/2015 و حتى 01/01/2050

# تحت Hj_date في الاكسيل نكتب معادلة تحويل الهجري و هي:

=text(G_date,"b2dd/mm/yyyy")

# في عمود جديد في الاكسيل نكتب معادلة التاريخ الميلاد و تكون :

=text(G_date,"dd/mm/yyyy")

#بعد ذلك نقوم بنسخ الثلاثة اعمدة : Convert_id , Hj_date , العمود الاخيرالرابع

# لصق القيم فقط Paste Values في شيت جديد

# بعد هذا يمكن استيراد البيانات مباشرة الى اوراكل باستخدام الTOAD و ان كنت افضل الاستيراد باستخدام جملة INSERT

# طبعا لن ارهقكم في كتابة جملة INSERT  عدد 12866 مرة و هذا مستحيل

# نقوم بكتابة جملة INSERT في الاكسيل كما هو مرفق ثم عمل نسخ و لصق للقيم فقط Paste Values 

#نسخ جملة INSERT الى متصفح Browser من خلال الدخول الى 

http://localhost:556...s/workspace.uix

كما هو معروف و عمل Execute

و بهذا تم ادراج جميع التواريخ الميلادي (01/01/2015 حتى 01/01/2050) و الهجري (11/03/136 - 08/04/1472) في الفترة المحددة .

Configure and Call Report from a Form ORACLE 10g

Assalamu Alikom ,



After many attempts to run  a report from the current form in ORACLE 10g.



I found this is the easiest method.



Update #1 :

To display Arabic Characters without bugs  of Reports , follow these steps :

1# Go to Start Menu then type REGEDIT press Enter

2# Search For Reports_Path then add C:\Windows\Fonts (the Windows Font Folder)

note that there may be more than REPORTS_PATH in Registry , so edit all found.

3# Then Go to c:\DevSuiteHome_1\tools\common\  and replace file uifont.ali  with this one (download from here...)

Your are done...

Update #2 :Also to make The Default Direction right to Left :

1#Search  for NLS_LANG  in Registry and replace all values with :

ARABIC_UNITED ARAB EMIRATES.AR8MSWIN1256 

Update #3 :Also to avoid errors while displaying Arabic chracters and Errors like TIMES.TTF

you must add path like following:

C:\oracle\jdk\jre\bin\classic;C:\oracle\jdk\jre\bin;C:\oracle\jdk\jre\bin\client;C:\oracle\jlib;C:\oracle\bin;C:\oracle\jre\1.4.2\bin\client;C:\oracle\jre\1.4.2\bin;C:\oracle\product\10.2.0\db_1\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files\Microsoft SQL Server\110\Tools\Binn\;C:\Program Files\Microsoft SQL Server\120\Tools\Binn\

Update #4 :Create Report Server :

Open START menu then open RUN then write down :

rwserver server=empsrv

First we assume we have EMPLOYEES Report and  DEPARTMENTS Form.


EMPLOYEES Report  SQL:

Select last_name
, salary , department_id

From employees

Where department_id=:p_dept



--where :p_dept is  the user parameter in reports.



DEPARTMENTS Form SQL select * from employees


we create a button   and mark  Mouse Navigate :NO

and  when_button_pressed trigger:

web.show_document('http://nextpast-pc:8889/reports/rwservlet?server=empsrv&destype=cache&desformat=pdf&report=E:\Faramawy\cscourse\Areej_Script\Reports\emps.jsp&userid=hr/hr@orcl& p_dept ='||:department_id);

--where p_dept  is case-sensitive  as it was written in Reports.

--and  :department_id is the name of department_id column shown on Form.

#Before Running form you must run Reports Server as following :

Start--Run-- rwserver server=empsrv

-- where empsrv  is the name of Reports Server

Oracle 10g Arabic Character

When you enter Arabic data into  Data Base and retrieve it , you may face many errors like displaying Arabic fonts in " ???"  or any other unknown format.



Here's the way solve it :



 1. Run then  REGEDIT  then  Search for NLS_LANG then REPLACE any existing value with  AMERICAN_AMERICA.AR8MSWIN1256 #Update

2.CONTROL PANEL the   REGIONAL and LANGUAGE then ADMINISTRATIVE then CHANGE SYSTEM LOCAL to ARABIC then OK then reboot..



3.RUN then SQL PLUS then SYS/SYS as SYSDBA then OK then run the following commands:

SHUTDOWN IMMEDIATE;

 STARTUP MOUNT; 

 ALTER SYSTEM ENABLE RESTRICTED SESSION; 

 ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0; 

 ALTER SYSTEM SET AQ_TM_PROCESSES=0; 

 ALTER DATABASE OPEN;

ALTER DATABASE CHARACTER SET internal_use AR8MSWIN1256 ;

ALTER DATABASE CHARACTER SET AR8MSWIN1256;

ALTER DATABASE NATIONAL CHARACTER SET AL32UTF8;

SHUTDOWN IMMEDIATE; -- or SHUTDOWN NORMAL;

STARTUP RESTRICT;

STARTUP;

STARTUP FORCE;

4. Now it should run correctly and display Arabic language without errors.

hoping it helps you.

Drop-Down List Change Depending on Secondary in Excel

This is a very simple way to make primary drop-down list that affects an other secondary drop-down list  in Excel:

Step 1

Click the "+" sign at the bottom of Excel 2013 to create a new sheet to use as a data source.

Step 2

Enter the values you need for the first drop-down list in column A on the new sheet. These values should begin with a letter or underscore and not contain spaces.

Step 3

Enter the respective secondary values in the next columns for each value entered in column A. For example, if you entered "Speakers," "Adapters" and "Cables" in cells A1 through A3, fill-in the appropriate values in columns B through D. Because you have three categories, you need three secondary columns, one as a secondary source list for each category. The secondary columns have no naming restrictions and can contain a different number of values.

Step 4

Click and drag your mouse across the data cells in column A to select them. Click "Formulas," "Define Names" and then "Define Names."

Step 5

Enter a descriptive name for the cells and click "OK." The name follows the same restrictions as described earlier. You can use varying capitalization in the name to help identify separate words, such as "ProductCategories," but you do not need to mirror this capitalization when later referencing the defined range.

Step 6

Define names for each secondary data list using the Define Names feature that was described earlier. The name for these lists should mirror the value of the main categories. In the previous example, cells B1 through B4 should be named "Speakers," cells C1 through C8 should be named "Adapters" and cells D1 through D5 should be named "Cables." These example ranges assume values are entered in each cell; you shouldn't include blank cells in the defined range.

Step 7

Click the original sheet tab and select the blank cell in which the primary drop-down list should appear.

Step 8

Click "Data," "Data Validation" and then "Data Validation" again.

Step 9

Click the "Allow" drop-down list and select "List."

Step 10

Enter "=ProductCategories" (without quotes here and throughout) in the Source field and click "OK." Replace "ProductCategories" with the name you defined for the primary source data. This creates the primary drop-down list that feeds the secondary list.

Step 11

Click the cell in which the secondary drop-down list should appear. Select "Data," "Data Validation," "Data Validation."

Step 12

Click the "Allow" drop-down list and select "List."

Step 13

Enter "=Indirect(A1)" and click "OK." Change "A1" to reflect the cell address where the primary drop-down list appears. If you receive an error, disregard it; it only appears because no option has been selected from the primary list yet. Once you select any option from the primary list, the secondary list changes to reflect the associated values.
