Hi,
I am not familiar with Java setting in Oracle
I have a a stored procedure that call a java program to execute host command like
ssh user1@localhost '/home/user1/someprogram'
if we execute this directly using PuTTY
we can do the following with no problem
su - oracle
ssh user1@localhost '/home/user1/someprogram'
but when we execute the stored procedure,
we have to do
*/usr/bin/ssh* user1@localhost '/home/user1/someprogram'
does anybody where to set the path or environment to make the java know the path correctly.
thanks

OK. You can try the following:
Login as the Unix user (e.g. oracle) on the pre-upgrade environment and run the following command.
echo $PATH
Repeat the above in the post-upgrade environment and compare the two outputs. Generally, PATH will be set using an environment script called from .profile of the user or it could be directly defined in .profile.
You can check this by examining the .profile after logging in as the OS user (e.g. oracle):
vi ~/.profile #i.e check the .profile in the user's home directory.
It's my best guess, as sometimes the PATH could be added later on (for. e.g by another script). Anyways, give it a try and tell what you find.

Not able to create Oracle External Procedure to Run Host Commands
Trying to follow this article
http://timarcher.com/node/9
Its related to
Oracle External Procedure to Run Host Commands
steps
1)mkdir –p /u01/app/usfapp/oracle_external_procs/oracle_host
2)
Author is suggesting to create a file
but header file is missing in very first line... may be not sure..say it is <stdio.h>Create a file named oracle_host.c. The contents of this file will be:
#include
int RunCmd(char *cmd)
return(system(cmd));
4) Create the file named makefile. The contents of this file will be:
oracle_host: oracle_host.o
gcc -shared -o oracle_host.so oracle_host.o
$ cat makefile
oracle_host: oracle_host.o
gcc -shared -o oracle_host.so oracle_host.o
5)
Now run the command make
The output on my server looks like:
[u01/app/usfapp/oracle_external_procs/oracle_host]
banner@usfbannerte [TRNG] > make
gcc -shared -o oracle_host.so oracle_host.o
here I stuck .. Not able to run this step ]$ make

How java runs in command prompt and why java runs on it
how java runs in command prompt and why java runs on it
command prompt was used before the development of IDEs like RAD,eclipse etc.
its still used for better understanding of the compilation and errors.
type the java file and save the file(source file) in the bin folder of ur jdk environment with extension .java. the source file must be the one that has the main method declared.
in the cmd prompt screen , set the path of bin folder.
eg:C:/program files/jdk(some version)/bin/...
for compilation,type:
javac (source file_name).java and press enter
for running the file:
java source file_name -

Hi,
We use JAVA source in Oracle to execute some unix commands directly from within stored procedures in Oracle.
Our Java source looks like this :
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED "HOST" AS
import java.lang.*;
import java.io.*;
public class Host
public static void executeCommand (String command, String etype) throws IOException
String[] wFullCommand = {"C:\\winnt\\system32\\cmd.exe", "/y", "/c", command};
String[] uFullCommand = {"/bin/sh", "-c", command};
if (etype.toUpperCase().equals("W"))
Runtime.getRuntime().exec(wFullCommand);
else if(etype.toUpperCase().equals("U+"))
Runtime.getRuntime().exec(uFullCommand);
else if(etype.toUpperCase().equals("U"))
Runtime.getRuntime().exec(command);
CREATE OR REPLACE PROCEDURE Host_Command (p_command IN VARCHAR2, p_etype IN VARCHAR2)
AS LANGUAGE JAVA
NAME 'Host.executeCommand (java.lang.String, java.lang.String)';
We call one unix shell script and discover that some UNIX commands from this shell script are executed and others not. A cp & touch command don't give problems whilst cat & unix2dos commands don't function.
Can anybody help me on this subject?
Thanks !
KrisHi Avi, thanks for your reaction. Got it to work with the unix scripts, the problem was a syntax error in the script itself.
However I don't get it to function when I try to run a unix command directly. Normally the parameter U+ should decide to start it in a shell for scripts and otherwise it should run the command directly. (whithout the /bin/sh in front of it).
I already adapted my source to try to execute the command in a new shell but without success :
String[] uFullCommand = {"/bin/sh", "-c", "\'cp /export/home/caluwaek/test/bestand2 /export/home/caluwaek/test/bestand8\'"};
I tried to put the whole command in one string, in 3 strings, to just call the cp command without bothering the shell. Nothing seems to work.
In unix both the following work :
cp /export/home/caluwaek/test/bestand2 /export/home/caluwaek/test/bestand8
and
/bin/sh -c 'cp /export/home/caluwaek/test/bestand2 /export/home/caluwaek/test/bestand8'
Thanks for your help!

HOST command not working in forms 10g
Hi,
I have migrated forms 6i to forms 10g, and having a requirement to open sqlplus prompt using a form menu. I have used the below command: -
"host('sqlplus '||user_name||'/'||pass||'@'||sid, no_screen);"
But I am not able to get the sqlplus window, and the main form is still in process for long time, till i bounce the server.
The forms are deployed on Oracle Applications Server 10g and i want to run it on server side.
Please help me with the problem.
Thanks,
AnkitThe deployment architecture is different between forms 10g and forms 6i.
In Forms 6i HOST built-in command will run on the client machine since you are running as client/server, but in WebForms (Forms10g) the HOST built-in command will run on the middle tier which is your application server machine.
In order to run hosts commands in WebForms you need to use webutil and use CLIENT_HOST in the webutil.
check the [Forms 10g R2 Demo|http://download.oracle.com/otndocs/demos/Forms_Demos_10gr2.zip] for sample codes of webutil.
You are using NO_SCREEN in your example, this will hide the window.

Use Host command in Oracle Database Trigger
I need to run Host command from a database trigger in order to execute a sh file in a Solaris, Unix, environment. How can I do it? The database environment is in Solaris and the database is 10g.
Please let me know as soon as possible.Hi,
read this <http://devtrigger.blogspot.com.br/2012/08/svn-backup-on-unix-or-solaris.html>
Or
you can to run in nohup. For example
You can a script with the command vi about your trigger and run with the sintaxe bellow:
nohup sqlplus "/as sysdba" @script.sql &
Where "script.sql" is the name of the your file.
Kind regards,
