Host command in WIN XP

hello
I want to copy a file in server to my local pc through my forms menu. I am using developer 6.0
In the menu I give this statement
host ('copy \\ibm-netfinity5k\developers\pro\help\*.* C:\MTB-ERP\*.*') ;
I am unable to copy the files. There is no attribute set like read only etc.
When I run the same above command from dos prompt directly , it works.
Please suggest a solution to the above cmmd.
Thanks in advance.

did you already try
host ('cmd /c "copy \\ibm-netfinity5k\developers\pro\help\*.* C:\MTB-ERP\*.*"') ;

HOST command and Forms 4.5

We were using HOST command(to start SQL Plus) in one of the form of our application (forms version 4.5) and this application was running fine on Win NT. Now this application is moved onto Windows 2000. Now we noticed that once the HOST command statement is executed, the application goes into hang and has to terminated. We fixed this problem temporarily by putting a message() and pause statement before and after HOST command statement and the application is running fine. I would like a better solution to this problem. If anyone has encountered this kind of problem or any idea, please reply.

Hi, there,
I have the same problem with my program. Have you figured it out the solution? and if not, could you show me the code of your temporary fix? my email is: [email protected]
Thanks

Run like Host command in plsql

Hi,
We are using Host command in sql*plus , but i need to implement like host command in Plsql. I refered previous post and some other links , that most of them are prefered only java stored procedure, And even that restricted previllage.
Can you give some sample example launchiing Win OS command in plsql
venki

To run a batch file, you need to use the Command Shell (and please do not call it a DOS shell like some people tend to do as it is not DOS). E.g.
c:\windows\system32\cmd.exe /c c:\temp\test.bat
We're running cmd.exe with switch /c that tells cmd to execute the command we're passing it, and then to terminate.
Note that we cannot interact with the shell from the PL/SQL side - we cannot answer prompts and so on. The script run, must be a proper batch/non-interactive script.
Also, the Oracle Server process (Win32 thread actually) that is servicing our Oracle client connection, is running the command for us. This thread itself is a background service process. It could run in Windows configured environment (VM/Virtual Machine) that is not allowed to interact with the desktop - or have limited or no access to certain files, folders and programs.
Technically speaking, this is what happens:
1) we pass the command to execute from our client to the Oracle server session servicing us
2) this Oracle thread uses the Java VM to make a Win32 call called CreateProcess()
3) the Win32 kernel executes that process
4) the process starts, runs and terminates
5) the Java VM inside the Oracle Server process regains control and pass the exit code and standard output of that process to PL/SQL
6) PL/SQL in turns, returns that very same data to our client
If you for example run a program that pauses and expects input, or hangs.. it will cause the above series of steps to stop at step 4. With the Java VM waiting on it to complete, and we waiting for the Java VM and PL/SQL call to complete.

Calling a Host Command

Dear Friends,
Is it posible to call a host command (windows) from PLSQL (Oracle 9i) ?
Thanks.

Using HOST command to copy files

Platform is Win network (98/NT/2k Prof), application is loading a picture into a blob field. Button executes the get_file_name built in to let the user select a file from the network, but code must copy the file to a directory that is on the oracle server so that the bfilename function can access a local directory. Then I can use dbms_lob.loadfromfile to actually load the picture.
The problem is that I cannot formulate a correct command for the HOST built in that will copy the file. I use message to display the command variable and it looks right, but the file does not get copied and the HOST command does not return an error.
Any help would be appreciated, thanks.
Mark.

Hi Mark,
You can use the library d2kwutil. It should be in a directory of the Developer demo's.
In this pll-file, there a procedure which enable you to copy, delete and move files on Windows.
Hope this helps!

Ah,it's in \%orahome%\tools\devdem60\demos\forms\,I got it,it's Win_api_utility procedure,it has copy_file,delete_file etc.
It's very good.:)

Forms HOST command no longer works after database upgrade from 10g to 11g

Hi,
After upgrading the database 10g to 11g the forms HOST command no longer works on Unix server. The form used to work fine prior the upgrade. I read all the threads I could find and did not see any solutions. Adding PATH and LD_LIBRARY_PATH does not work because it does not even run a basic shell script. (I saw this solution, adding PATH and LD_LIBRARY_PATH, in many questions / threads).
1. I wouldn't expect the database upgrade to be an issue, but it is the only change we had.
2. Note, 11g is Oracle Fusion Middleware which is quite a bit different than 10g.
I even tried the most basic commands like "echo" which is a build-in Unix command and there is no directory for it (ie. no /usr/bin - so variable PATH is irrelvent). i.e HOST('echo hi'); and HOST('echo "hi" '); and even HOST ('echo hi > /my_file.txt'); all returns FORMS_FAILURE (actually the if is IF FORM_SUCCESS THEN ... else ... and the else part always runs now - whereas it didn't before.).
Or basic commands like /usr/bin/ls as in HOST(/usr/bin/ls). At that point I was just testing the Unix command would return FORM_SUCCESS even though I could not see the results (because they weren't writing to a log file). Notice that I'm using the direct path /usr/bin so no Unix environment variables were needed.
The form does use webutil but that part works. For example, we have webutil_file_transfer( ....) The file shows up on the application server and in the expected directory.
Here's the main goal. Upload a file from clients local PC to the datebase server. The form uploads the file to the Application server, then we have a Unix script to scp (secure copy) the file from the application server to the database server. IF webutil, or any other Oracle functions could put the file on the database server that would be better. But, I don't know of any procedures that do that - or would have done it cleanly (i.e. storing to database and write back to server and then using a blob etc. )
Anyway, I was hoping someone would help with either of these.
1) Get the HOST command to work. - If we can get that to work then I wouldn't need any more help. We can just call the already existing Unix script to copy the file from the application server to the database.
2) OR be able to upload directly to the database server - wanted to do that originally
Any help would be appreciated

Solution for those interested and for anyone else searching this forum for a solution
I found this on My Oracle Support:
<h3>Host Command from Forms Not Working in 11g in Sun Solaris Sparc OS [ID 1157346.1]</h3>
Applies To: Oracle Forms - Version 11.1.1.1.0 and later
Sun SPARC Sun OS
Symptoms:
When trying to execute a Shell script or any OS command using the host() Built-in from Forms 11g, the host()command is not getting executed. The same functionality works on other operating systems and in previous versions like 10gR2.
Steps to be followed:
1) Take a backup and edit the $DOMAIN_HOME/config/fmwconfig/servers/WLS_FORMS/applications/formsapp_11.1.1/config/default.env or any custom environment file.
2) Locate the following environment variable:
LD_PRELOAD=/ora10gas/app/11.1.0/Middleware/as_1/jdk/jre/lib/sparcv9/libjsig.so
3) Comment out this variable. After the changes, it will look like the following:
#LD_PRELOAD=/ora10gas/app/11.1.0/Middleware/as_1/jdk/jre/lib/sparcv9/libjsig.so
3) a) Instead of LD_PRELOAD, kindly use LD_PRELOAD_64 as given below :
LD_PRELOAD_64=/ora10gas/app/11.1.0/Middleware/as_1/jdk/jre/lib/sparcv9/libjsig.so
(This makes HOST AND RUN_REPORT_OBJECT work fine).
4) Save the file and execute your forms. The Host() built-in will work as expected
The LD_PRELOAD setting in default.env is only required for the working of signal chaining facility in JVM version 1.5 and later. If you are not using theSignal chaining facility, this variable is not required. For more information, refer to the following documentation
http://download.oracle.com/docs/cd/E14571_01/doc.1111/e14772/forms.htm#CJAJGAFF

Host command is not working on linux

Hi
I m using linux for application server n windows for client. I need to create folder from client machine by cliking a button of forms10g runtime.HOST command is not working which was working fine in windows.
Any help is appriciateable.
kazi mokarem

Hi
I had the same issue on linux a few weeks back. What tuned out was, when you install the Oracle app svr it does not include the system paths by default.
The path where mkdir is located may not be visible to the app.
Try to hardcode the path for mkdir as /bin/mkdir .... and seee if that works.
If the above statement works then add that path in the paths variable in default.env file located in $ORACLE_HOME/forms/server directory

How to run a HOST command from Report 2.5

Hello everybody,
I want to pass an unix command from a Report. I am running the report (Report 2.5) on an Unix server and I want to pass a unix host command inside the Before Report Trigger of the report. But Report2.5 is not recognising the HOST built-in. Is there is any way around?
Thank in advance.
Samujjwal Basu

First off is that openssl command correct? Should it be this instead:
openssl pkcs8 -inform der -nocrypt -in test.der -out result.pem
Try out your openssl command within a command prompt so that you know that it works ok. I think the command line you specified waits on stdin (well it does for me).
After that.....
runtime.exec creates a Process object. If you do this:
Process openssl = runtime.exec("....")
then you can examine the return code from openssl to see the exit code - for instance if the input file does not exist then exit = 1. You can test for this with Java
Alternatively you could get the stderr from the process and look inside it - if it is 0 length then all is good, if it has some text in there then it has likely failed. You could then throw an exception and include the stderr output in the exception messgae. You may need to experiment with this, runnig it first when openssl is happy then running it again when openssl is upset.

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,
Ankit

The 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 forms 6i

hi
all
i use Oracle forms 6i i run in a web and in that i have connect one server so,
i have to use Host Command and i have to fire this command
host (' net use \\windchillsvr\e\jyotionline /user:dwg_users dwg_users');
But it's Not Connect
My Forms in run in Web
so help

JavaBean does d othe job for you but it requires signing process; I used it when I was working on forms6i for our project.
I could use another approach that is the file type command executable which it stays in client's PC to do it and it does not requires signing at all since I am now working on the Java EE project for downloading and launching the third party tool in client's PC.
I plan to write a article for forms use, which could do all the heavy WebUtil can do, but not need to go thru the signing process.

Problem with program hanging randomly on certain commands from win 7 pro client to SB Server

Having a problem with program hanging randomly on certain commands from Win-7 Pro Client to SB Server Both 64-Bit
Five other slower XP-Pro 32 Bit systems though they are older and slower systems do not seem to hang as readily if at all.
It has been very frustrating as the Client-System, SB-Server and Program should work w/o any hitches, but this seems to work fine @ times and then hang randomly.
Would appreciate any and all suggestions in assisting.... JimBAgde-MSS

You can try this, as I have had similar problems with another MS Access .MDB file and slow access before. This fixed my problem for me. On the slow computer, make sure the program is set to see the .mdb file via UNC path, not a mapped drive letter. ex.
USE: \\yourserver\shared\dental\file.mdb
DO NOT: S:\\shared\dental\file.mdb
hope this helps

How can I use variable name as a prameter value in HOST Command ???

Hi All,
How can it possible to use variable value in parameter in HOST command ??
Following in my code:
host('rwclient server=reptest report=c:\cust_print.rdf p_1= s_sam_cust_id userid=wh1/wh1@dwh desformat=pdf desty=file desname=c:/temp/'||v_sam_cust_id||'.pdf');
Regards

Hello,
The Syntax of the builtin HOST is :
SyntaxPROCEDURE HOST
(system_command_string VARCHAR2);
PROCEDURE HOST
(system_command_string VARCHAR2,
screen_action NUMBER);
So , you can build the system_command_string as any VARCHAR2
Example are provided in online help :

hi,
my db is 9.2
i'm aware of schedule you mentioned , but if it's up to the task , you don't know when a row with certain value is inserted
simple way :
when a row inserted into a table with value "catch me" you want to know who inserted this test value
so you tried to create a trigger to catch program, machine, module ,and terminal info from v$session
so you can figure out where it is coming from
and i want to go a step further , by executing some os command to digging out more
and i come up with this , when value 4 is inserted i exec a procedure host to execute command,
the problem is it's not working as i exepcted , so spare me the lecture of reading docs and just tell me what to do
i'd really appreciate it , thanks

HOST command does not seem to work in deployment system

I am developing forms software for a SUSE Linux system, but the HOST command does not seem to operate correctly when used in conjunction with Application Server.
All I am trying to do is launch Adobe Acrobat reader as a background job using the command :-
HOST('/opt/Adobe/Reader8/bin/acroread &');
but nothing seems to happen.
If I enter the command :-
*/opt/Adobe/Reader8/bin/acroread &*
directly from a shell window (using the same login account) the command works correctly.
I have tried other commands e.g. directory listings etc and all seem to have the same problem.
Furthermore when the same form is run from the development environment using "Internet Developer Suite" it operates correctly with no problems.
I am running on a deployment system where all three tiers of oracle are on the same machine (i.e. Database, AS and web front end).
Can anybody suggest any possible causes or anything I can try to help resolve this problem ?

brian_a_j wrote:
Although I still dont understand why HOST would not work given my configuration (the Application Server and Web Browser operate on the same machine).One little test, put the execution command in a shell script and try to execute the script with the HOST command instead of the command itself.
Using HOST the script will be executed on the AS machine no matter from where it is executed.
