How to call Operating System commands / external programs from within APEX

Hi,
Can someone please suggest how to call Operating Systems commands / external programs from within APEX?
E.g. say I need to run a SQL script on a particular database. SQL script, database name, userid & password everything is available in a table in Oracle. I want to build a utility in APEX where by when I click a button APEX should run the following
c:\oracle\bin\sqlplusw.exe userud/password@database @script_name.sql
Any pointers will be greatly appreciated.
Thanks & Regards,

Hi Guys,
I have reviewed the option of using scheduler and javascript and they do satisfy my requirements PARTIALLY. Any calls to operating system commands through these features will be made on the server where APEX is installed.
However, here what I am looking at is to call operating systems programs on client machine. For example in my APEX application I have constructed the following strings of commands that needs to be run to execute a change request.
sqlplusw.exe user/password@database @script1.sql
sqlplusw.exe user/password@database @script2.sql
sqlplusw.exe user/password@database @script3.sql
sqlplusw.exe user/password@database @script4.sql
What I want is to have a button/link on the APEX screen along with these lines so that when I click that link/button this entire line of command gets executed in the same way it would get executed if I copy and paste this command in the command window of windows.
Believe me, if I am able to achieve what I intend to do, it is going to save a lot of our DBAs time and effort.
Any help will be greatly appreciated.
Thanks & Regards,

Is it possible to call operating system command after file receive?

Hi expert,
I'm trying to call operating system command after file receive comm.channel receive a txt file.
operating system command uses txt file name as parameter.
Is it possible? How?
Thanks.

Hi,
It should be possible, actually we have two options that are
1.RUN OS command before message processing
2.RUN OS command after message processing.
So you can give the commands in the RUN OS command after message processing.

How to use Operating System Commands while using define in sqlplus

How to use Operating System Commands while using define in sqlplus . The Host OS is Linux
define report_name=PROD_${host date "+%b"}.html
The above is not working.
The output should be
define report_name=PROD_JAN.html
Regards,
DB

of course I was talking nonsense: the problem here is the mixing of bind variables and DEFINE variables.
With the following changes the script should work (the conditions for begin_interval_time are perhaps not what you want):
variable snap1 number
variable snap2 number
variable rptname varchar2(20)
begin
SELECT min(snap_id) into :snap1 FROM dba_hist_snapshot WHERE CAST(begin_interval_time AS DATE) >= SYSDATE-1;
SELECT max(snap_id) into :snap2 FROM dba_hist_snapshot WHERE CAST(begin_interval_time AS DATE) >= SYSDATE-1;
end;
col file_name_value new_value report_name noprint
select 'PROD_'|| to_char(sysdate,'MON') || '_' || to_char(sysdate,'DD') file_name_value from dual;
define report_type = 'html'
define num_days=2
define begin_snap=:snap1
define end_snap=:snap2

get

same error;

Process management at the OS level should prevent execution continuing in the calling code until the command has completed (either successfully or with error).
If the low level java code were to spawn child process threads then execution could continue, but I'm guessing the Java function your talking about doesn't do that and just calls the operating system to execute the command and waits for the returning code to come back.

How to Run Operating System Command Before/After Message Processing SAP PI

Hi,
We are trying to execute multiple commands via "Operating System Command Before/After Message Processing".
When we use single command say for example cp or mv (copy or move) the commands get executed fine.
eg: cp %F /var/opt/data/outbound/Test/Dummy.txt
/this works fine/
when we club commands together or try to redirect the outputs of commands, none of the commands get executed.
eg:
cp %F /var/opt/data/outbound/Test/Dummy.txt ; rm %F
or
wc -l %F > /var/opt/data/outbound/Test/Dummy.txt
Is it possible to execute multiple commands or redirect the output of commands without using a shell script? The PI server we are working on iis hosted on UNIX environment.

Hi Harleen,
try like this
cp %F /var/opt/data/outbound/Test/Dummy.txt ; rm %F
instead of semicolon try this
(1) &
command1 & command2
Execute Command1 and then execute Command2
(2) &&
command1 && command2
Runs the command2 only when command1 doesn't Complete successfully
(3) ||
command1 || command2
Runs the second command if the first command had an error
(4) ()
(command1 || command2) || (command3 & command4)
Defines the order in which commands are to be executed

How to execute operation system commands by using TSQL without enabling xp_cmdshell.

Hi Experts
Looking for advise if one can use operation system commands using TSQL without enabling xp_cmdshell.
actually using xp_cmdshell requires sysadmin privs which I am unable to provide (directly or using proc) to a user but the user needs some operating system commands to execute for file manipulation from sql server session. Please share your thought.
Best Regards
khalil

>but the user needs some operating system commands to execute for file manipulation from sql server session
See article here
http://www.mssqltips.com/sqlservertip/2014/replace-xpcmdshell-command-line-use-with-sql-server-agent/:
"Problem
I need to run something from the command-line, but based on best practices xp_cmdshell has been disabled. The task that needs to run is an internal process that will originate from within SQL Server. Is there a way to do this without using xp_cmdshell?
Solution
The use of xp_cmdshell is generally frowned upon and is now recommended to be disabled, unless it is absolutely necessary. There is a solution that works around this restriction via the use of SQL Server Agent.
Wherever SQL Server is installed, SQL Server Agent is installed with it (except for SQL Express). SQL Server Agent has the ability to run job steps which invoke the command shell. And in the case that the job is owned by a member of the sysadmin fixed server
role, the job will execute as the service account under which the SQL Server Agent is running. "

How to call operating system(windows) functions like sutdown,refresh,et

Hello,
I am new in Oracle D2k.I want to know that how to call windows XP/7 shell commands(operating system functions) or windows function key(like F5 for system refresh in windows xp/7) in an Oracle Form.
Actually I have to make a trigger which can fire at pressing a particular key and execute appropriate action of Windows7 like shutdown,F5(function key of windows to system refresh).
thank you
regards
aaditya.

Just for future reference, regardless if you are posting in the Forms area of the forum or any other, terms like Forms 11g, Oracle 11g, etc are parts of product names. They are not version numbers although they do offer a slight hint. It is very important that when posting you include the complete version number of any products related to the problem or question you have. For example, you said you are using Oracle Forms 11g. Look at how many possible versions "Forms 11g" could possibly be:
11.1.1.1
11.1.1.2
11.1.1.3
11.1.1.4
11.1.1.6
11.1.2.0
11.1.2.1
With each new patch release and major release, a large number of bug fixes are included. In the case of new major releases, in addition to bug fixes, many new features are added. So knowing the version number is important.
Beyond that, it would appear that you have many questions:
1. How to copy and paste
2. How to execute a system shutdown
3. How to force the browser into full screen mode
4. Refresh - this one is unclear. What do you mean by "refresh"?
Let me answer those that I can:
<blockquote>o Functions like cut/copy/paste are available directly from your Forms code. For these I would recommend referring to the Builder's Online Help. Look for CUT_REGION, COPY_REGION, PASTE_REGION. It might also be helpful to understand SELECT_ALL. For example you may want to code a Copy button like this:
GO_ITEM('some_text_field);
SELECT_ALL;
COPY_REGION;o To execute a system shutdown on the client machine, you would first need to WebUtil enable your form. Refer to the Forms Builder Online Help for information about how to use WebUtil. You can also find lots of information in this forum about WebUtil. Once enabled, you can execute a Windows shutdown in various ways. Here one option:
Declare
     my_cmd varchar2(255);
Begin
     my_cmd := 'cmd /c start "" "' || '"shutdown -s -f -t 1"' || '"';
     WEBUTIL_HOST.HOST (my_cmd);
End;Refer to the Microsoft documentation for more information: http://technet.microsoft.com/en-us/library/bb491003.aspx
o I'm not sure what you are attempting to do with the F11. I understand that this function key sets the browser to full screen, but the form will not exactly adjust for this change in browser size. You can adjust the applet size dynamically, but not the form. For that you would need to code the behavior yourself. So, before I can offer something specific, it would be helpful to understand what you expectation is and if what you want is to set the browser to full screen, why not just allow the end user to do it? You could easily have a java script popup displayed before the form starts which might say something like "To maximize your browser, press F11"
o Finally, "refresh". I don't know what you mean here. Refresh what? The Windows desktop, browser, Oracle Forms.....
