Operating system calls from apex

Question about operating system calls from apex.
I created a java file which is wrapped with pl/sql like
create or replace java source named "ExternalCall" as
import java.io.*;
I do the steps from this web page http://www.oracle.com/global/de/community/tipps/oscalls/index.html
The page is in german, but for experienced users the code on this page says everything.
In apex i have an application which calls this function with the "move" command in a sql-report region.
Let's say move c:\work1\file.txt c:\work2\file.txt
Everything works fine on one host(pc) but if i want to transfer the file from my host to another one then
i get the messgage "no access" although i have read, write access on the other host.
By the way, on both hosts i have admin rights.
Why can't i transfer the file over a network ?
Thanks in advance for any kind of help.

You say that "on both hosts i have admin rights".
Remember that Oracle doesn't log in as "you", so Oracle may not have rights to the remote host.
There are a lot of different permissions that can be assigned to java stored procedures. This chapter in the documentation might help:

I guess you are working on a Windows host. In this case Oracle processes are running as Windows services with a build-in MS system account. This account has no access to network ressources. You have two ways to get out of your windows box:
Assign Oracle services a network enabled account, e.g. domain user with local administrator privileges. (I never tried this and I don't like to recommend it.)
Use a command script for copying files and use explicite authentication within this script:-
net use \\myserver\ipc$ tiger /user:scott
copy c:\temp\xxx1 \\myserver\share\temp
copy c:\temp\xxx2 \\myserver\share\temp

Operative System call from Composition Environment 7.2

Hello all,
what is the way to execute a shell script from SAP Composition Environment 7.2 (only j2ee stack).
....On an ABAP engine I know that the solution is true with a transaction that create a external system call, but on j2ee?
thank you!!

Hi Rajesh,
Please try to clear cookies and temp file from your browser. and try again. if issue still persist, then try again later

Cross platform operating system calls from Java

For our application we need to call an external program to perform FTP. We use ncftp as it's available on all the server platforms our clients use (Sun, HP, Linux, Windows). Up to now we've been using a Java program that listens to the Oracle pipe and sends a string to the OS.
Now we are using 8i we thought it would be better to use Java within Oracle as this should reduce problems due to the external program not running. On Windows it works fine, but on Linux runtime.exec does not seem to take account of the system path. If I send something like '/usr/bin/ncftpput ...' it works, but I can't rely on the executable being in that directory although it should be somewhere in the path. I want to just pass 'ncftpput ...'.
Ideally I want to be able to make the code OS independent, but would consider doing something in the Java part to detect the OS and adapt accordingly, perhaps by using a shell e.g. '/bin/sh -c ncftpput ...', but I've had problems with that using the whole command line and can I rely on having a specific shell on all *nix systems?
At some point we'd like to do all the FTP from within Oracle, but that looks like a bigger project.
Any ideas/suggestions?
Thanks
Steve

Steve,
To determine the OS, you should be able to check the System properties. As an example, when I run this (quick and dirty) sample code, I can see that os.name=Windows NT on my Windows instance:
CREATE OR REPLACE JAVA SOURCE NAMED "envTest" AS public class envTest {
public static void getEnvVar() {
System.getProperties().list(System.out);
CREATE OR REPLACE PACKAGE envTest IS
     PROCEDURE getEnvVar;
END;
CREATE OR REPLACE PACKAGE BODY envTest IS
     PROCEDURE getEnvVar IS
     LANGUAGE JAVA NAME 'envTest.getEnvVar()';
END;
To see the output after executing envTest.getEnvVar, map System.out to DBMS_OUTPUT before running it, as follows:
set serveroutput on
begin
dbms_java.set_output(100000);
end;
Hope this helps,

Calling Operating System Commands from PL/SQL using java

wlth help of given thread link,
Calling OS Commands from Plsql
but i had user privilege problem

abcd', 'SYS:java.io.FilePermission','<<ALL FILES>>', 'execute');
again
get
can't exec: /tmp/sri/GROUP_ho.sh lacks user privilege
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.

Call operating system services from Jdeveloper

How can i call operating system services from Jdeveloper ?

We do not use JDeveloper but use external procedures/routines called from the database. Then you can call a database procedure to an operating system task.

System Call from Java, problem LD_LIBRARY_PATH

I use class Runtime to invoke Operating System Call.
I want to run OS command gpg (gnu program for encrypting/ decrypting files).
What is interesting, when I run my sqlplus script from system user (used for database installation) call ends with success.
Running script from other os users or machines ends with -1 code and error message:
"ld.so.1: gpg: fatal: libiconv.so.2: open failed: No such file or directory"
gpg uses libraries given LD_LIBRARY_PATH (/opt/gnupg/lib:/usr/lib:/usr/local/lib)
I think that is the problem. Is there a workaround for that??
Best regard
Grzegorz

Maybe related to the fact that the PATH environment variable is unset then re-initialized by Oracle to PATH = /usr/local/bin:/bin:/usr/bin. Try using absolute path for the OS commands.

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.

Can I source an environment before making a system call from the database

I can execute system calls from the database like
Process proc = Runtime.getRuntime().exec("env");
but I am unable to source an environment before making the call.
Our goal is to from within the database to execute tkprof on a
raw trace file then load both files into clobs in a table. We can load
the raw trace no problem, we just cannot figure out how to execute
tkrprof on the raw trace then load its output.
Anyone know if this is possible to hava java get a runtime and then call
an environment file to source the environment so that path's and other environment variables are set prior to executing another system command.

Thanks for that...but can I do multiple edits in my Stored Procedure Vaibhav and pass back something that I can then utilize in my SSIS? For example...
One and Only one Member Span...so I'd be doing a SELECT COUNT(*) based on my match criteria or handle the count accordingly in my Stored Procedure and passing something back via the OLE DB Command and handling it appropriately in SSIS
Are there "Diabetes" claims...again probably by analyzing a SELECT COUNT(*)
Am I expecting too much from the SSIS...should I be doing all of this in a Stored Procedure? I was hoping to use the SSIS GUI for everything but maybe that's just not possible. Rather use the Stored Procedure to analyze my stged data, edit accordingly, do
data stores accordingly...especially the data anomalies...and then use the SSIS to control navigation
Your thoughts........
Could you maybe clarify the difference between an OLE DB Command on the Data Flow and the Execute SQL Task on the Control Flow...
You can get return values from oledb comand if you want to pipeline.
see this link for more details
http://josef-richberg.squarespace.com/journal/2011/6/30/ssis-oledb-command-and-procedure-output-params.html
The procedure should have an output parameter defined for that
I belive if you've flexibility of using stored procedure you may be better off doing this in execute sql task in control flow. Calling sp in data flow will cause it to execute sp once for each row in dataset whereas in controlflow it will go for set based
processing

Executing a Operating System command from Stored Procedure ??

I want to execute a Operating System command from a PL/SQL Stored Procedure, can anyone suggest me how can I do this ??
I am on Sun-Solaris with Oracle 8.1.7 database.
Please do email me at [email protected]
Thanks in Advance,

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.

Operating system call w2k and linux

Hello:
I am not a programmer but i nedd a routine to do an operating system call and execute a batch or shell set of commands,
do anyone know how can i do it?
thanks a lot in advance

Or maybe Runtime.exec is enough for you. MUCH simpler than JNI, as long as a shell executing a script is all you want.

Work Process tries to restart but fails - Operating system call fork:restar

Hi
We have a ECC 5.0 system running on v5r4 (6.40 kernel level 159). Some of the work processes fail and then try to restart and fail again. Thus there are many job log entries in both SAP and OS/400.
The OS/400 logs mention the PASE (unix executable environment) and MCH3203.
SAP mentions Operating system call fork:restart
OSS has note #884359 which mentions a palitative but despite being at 6.40 level 159 the parameter profile as/4/wp_max_restart is said to be "unknown" by RZ10.
We are making sure we are up to date with the APAR II14126 just in case this is the issue.
It did start after the time change but we are not sure this is the root cause.
We are also considering getting upto kernel 171.
Anyone else seen this issue?
thanks
Matthew Milne

We see those problems once a while, and usually they are gone when you restart the instance or after an IPL. You should report the problem to IBM, they will probably be interested in the LIC log entries that come along with the error (STRSST - Start a Service Tool - Licensed Internal Code Log). II14126 is probably a good start (for example, MF40759).
The profile parameter as4/wp_max_restart is only known to the kernel, because it is not intended as a permament setting, but only as a temporary workaround for the problem in the PASE environment. That's why RZ11 does not know about the parameter and reports it as unknown.
Kind regards,
Christian Bartels.
