How to: execute operating system commands from PL/SQL

System: IBM pSeries AIX
Oracle: 11g Enterprise
Is there a quick way to execute operating system commands from PL/SQL?
Without creating a JAVA class....
I need to execute a Loader script.
I want to do this from within PL/SQL.
I need to to do 4 things.
Three require SQL scripts.
The fourth is SQL*Loader.
The usual way is with a UNIX script calling 3 SQL scripts and one Loader control file.
Is there way to do all this from within ONE PL/SQL SCRIPT ??
Just let me know.

WHY ON EARTH, such action will create a new connection and become a resource hog?

Which is perfect for the purpose.

NO, there is NOT. Nor should there be. Why create unstable ineffcient Mickey Mouse systems, glued together by hacking?

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 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. "

Executing operating system command within trigger or procedure

Hello
Can some one help me out as how to execute operating system command (unix or windows ex.. stop,start,cc,del or copy etc...) in a trigger or procedure.
My requirement is, if some predefined error occure then listener listener should be stopped automatically.
Thanks in advance

Here is some code to tell you how to do:
First a small Java program that taker a string as a parameter and executes it as an os-command
import java.lang.Runtime;
import java.lang.Process;
public class Commands extends Object {
* Constructor
public Commands() {
// On NT the command should be like this "cmd /c del c:\temp\readme.txt"
// exec execute('cmd /c del c:\temp\readme.txt');
public static void execute (String cmd ) {
try {
Process p = Runtime.getRuntime().exec(cmd);
try {
p.waitFor();
catch (java.lang.InterruptedException intex ) {
intex.printStackTrace();
System.out.println("Return = "+ p.exitValue());
System.out.println(" Done ...");
catch ( java.io.IOException iox) {
iox.printStackTrace();
===================end of java ====
Use loadjava to load it into the database and create a pl/sql wrapper around the java code.
See the manual about loadjava details.
Log in to sqlplus as SYSTEM and create a role for this purpose e.g. 'JAVA_ROLE'
and exec the following as SYSTEM or SYS to make sure the user has the the needed privs.
dbms_java.grant_permission('JAVA_ROLE','SYS:java.io.FilePermission','<<ALL FILES>>','read,write,execute,delete');
dbms_java.grant_permission('JAVA_ROLE','SYS:java.lang.RuntimePermission','writeFileDescriptor',null);
dbms_java.grant_permission('JAVA_ROLE','SYS:java.lang.RuntimePermission','readFileDescriptor',null);
and you're done.

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,

Are you using a webserver? If so, you could make your operating system script into a CGI program, then execute it from pl/sql using utl_http.request.

Vista: use the windows program manager to execute operating system commands

attempting to run forms 6 on vista... the forms app attempts a call sqlplus using the host builtin to populate some tables before calling the report.
in windows vista i get a message box indicating "use the windows program manager to execute operating system commands".
is this windwos vista message? would this have to do with permissions?
any insight most appreciated and thanks in advance.

I don't know about the HOST-problem, but..
the forms app attempts a call sqlplus using the host builtin to populate some tables before calling the report.What about putting the logic from the SQL*Plus-scripts into a database-procedure and call that instead. I think,, with the current approach you will get problems at least when you have to migrate to Web (e.g. Forms 10g).

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

How can I pass system commands from a java program? Urgent!

I have been trying this out since a long time. How do I send system commands to command.com or cmd.exe from a java program and an output of the executed command back to the java application.
If u have any idea, or have any information about the kind os application reply back.
Thanks

This is the code which I tried, but it displays only the title of MS-DOS, something like " Microsoft Corp...etc ". But doesn't take any input, and the subprocess(cmd.exe) hangs.

DataInputStream din=new DataInputStream(p.getInputStream());
DataOutputStream dout=new DataOutputStream(p.getOutputStream());
System.out.println("after streams");
String s;
dout.writeChars("type cmddemo2.java");
while((s=din.readLine())!="\n")
System.out.println(s);
dout.writeChars("dir");

System.out.println(s1);

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 Power Shell Command From Windows Application.

Hi All Experts,
I want to execute power shell commands from my windows application.
Is it possible ?
Please let me know your comments..
Thanks.

I have not tried this, but apprently it is easy as in the sample pasted below. please see this article for more details
http://geekswithblogs.net/Norgean/archive/2012/09/19/running-powershell-from-within-sharepoint.aspx.
Let me know how it goes...
public string RunPowershell(string powershellText, SPWeb web, string param1, string param2) {
// Powershell ~= RunspaceFactory - i.e. Create a powershell context
var runspace = RunspaceFactory.CreateRunspace();
var resultString = new StringBuilder();
try
// load the SharePoint snapin - Note: you cannot do this in the script itself (i.e. add-pssnapin etc does not work)
PSSnapInException snapInError;
runspace.RunspaceConfiguration.AddPSSnapIn("Microsoft.SharePoint.PowerShell", out snapInError);
runspace.Open();
// set a web variable.
runspace.SessionStateProxy.SetVariable("webContext", web);
// and some user defined parameters
runspace.SessionStateProxy.SetVariable("param1", param1);
runspace.SessionStateProxy.SetVariable("param2", param2);
var pipeline = runspace.CreatePipeline();
pipeline.Commands.AddScript(powershellText);
// add a "return" variable
pipeline.Commands.Add("Out-String");
// execute!
var results = pipeline.Invoke();
// convert the script result into a single string
foreach (PSObject obj in results)
resultString.AppendLine(obj.ToString());
finally
// close the runspace
runspace.Close();
// consider logging the result. Or something.
return resultString.ToString();
Ok. We've written some code. Let us test it.
var runner = new PowershellRunner();
runner.RunPowershellScript(@"
$web = Get-SPWeb 'http://server/web' # or $webContext
$web.Title = $param1
$web.Update()
$web.Dispose()
", null, "New title", "not used");
