How do I stop ODI if my DOS BATCH file flags an error?

I have a DOS batch file as the first step in my ODI package. How do I send a code to ODI to tell it that it has failed and to stop processing the rest of the package? I was told I could use an ODI variable to accomplish this but not sure how.
Also, how do I pass a semaphore/flag an error in my DOS batch file to ODI ?
Thanks in advance for your help.
I tried to search for this info in John's blog: http://john-goodwin.blogspot.com/search?q=error
but was not able to find it.
:)

In your package 1st step is OS Command then some other steps involved, right ?
In that case you can have your package like this
OS Command (first step) ---------OK--------------> 2nd step -------------------> 3rd step
So your 2nd step will run only when the 1st step is successful, it will not start 2nd step as 1st itself has failed .
Thanks,

Hi,
Use CL_GUI_FRONTEND_SERVICES=>EXECUTE method to run any application in your case batch file..
The batch file you are trying to run should be accessible on presentation system i.e. user's machine.

How could I have a VI execute a DOS batch file?

I need to update the PC's hardware timeclock and the Windows clock via a VI front panel. If I can update hardware and windows timeclocks from a DOS prompt (TIME/NEW TIME), is there a way to provide a LV interface for the same operation? If a VI could run a DOS batch file, having the operator enter a new time in a DOS prompt window is the next best thing.
Thanks,

Have you tried right clicking the VI and selecting Help?
I found the online example by selecting help. I'm using LV 5.1 and I've noticed that offline help is not as detailed as it is with LV 7 Student Edition (I have student edition at home).
In my latest attempts, I have the string "command.com /c time" wired to the command line input of system exec.vi. I get the dos prompt and a request for a new time.
To avoid the operator having to enter the time in the DOS window, I tried passing carriage returns and a time update value in the command line input. It didn't work. Do I have to add a system exec.vi for each command line entry and concatenate the vi's somehow?
Thanks,

Scheduling unix shell scripts from windows using DOS batch files

Hi,
I want to schedule unix shell scrips using windows scheduled. I have the option of scheduling the DOS batch files. But not able to connect to telnet using DOS. Please let me know if there is an option.

Drive letters are user specific. When you run jboss it runs as you, with your shared drives. When you run it as a service, it runs as guest or another user so your drive letters are meaningless.
Either setup the user or use UNC

Irregular delay while running a dos batch file using a servlet class

i used RunTime( ) class to execute a dos-batch file containing some commands like changing the directory, running an exe(executable.exe) file...etc in a servlet class. while this servlet class is invoked, the exe file(executable.exe) is run after irregular delay at different trials.
Note: When this batch file is run in a stand alone java class, it is working fine.
what can be the possible cause of this prob? Help me in this.

It's ok - I've found the answer.
I'll post it here for anyone else who is interested.
The problem stemmed from the fact that I had to put the path to javaw.exe in quotes, as the batch file is dynamically generated from the user's environment, and then run. The user's system properties gives a path to java home using a full path name, which WinNT/Win2K doesn't like.
The following batch file content solves it, closing the DOS box after starting javaw.exe. Before this part of my batch file, there is just some file copying that goes on for the autoupdate process.
set PATH=%PATH%;"D:\Program Files\JavaSoft\JRE\1.3.1\bin"
start /B javaw.exe -Dmyapp.home=C:\myapp myapp.client.MyAppClient subSys
exit
The parameter subSys is just a command line parameter that MyApp.java looks for, so not relevant for everyone.
/B prevents a second DOS box from opening.
exit simply closes the DOS box once the javaw.exe process has started.
Too easy! Although I can't believe how difficult it was to find information about this. Hopefully it will be of benefit to others.

Run a MS DOS batch file from the client

Hi,
I created a java source to run a bat file, the folder is loacted in the Database server.
(Not in application server)
create or replace and compile java source named execcommand as
import java.io.*;
import java.util.*;
public class ExecCommand{
public static void run(String cmdstr) throws IOException, InterruptedException
try {
int rtn;
cmdstr = "cmd /c " + cmdstr;
Process prcs = Runtime.getRuntime().exec(cmdstr);
while (prcs.getInputStream().read() != -1 ) {}
catch (IOException e) {
e.printStackTrace();
I called the java source from the procedure
create or replace procedure run_batfile is
begin
execcommand(cmdtext => 'e:\services\genPDF.bat');
dbms_output.put_line('file created successfully');
exception
when others then
dbms_output.put_line(sqlcode || sqlerrm);
end run_batfile;
But the bat is not executing (The bat file is to generate a PDF file ). Bu when i executing this from my PC (Client PC) directly on the RUN , its generating the PDF file in the server.
What could be the problem, What should be the path in the procedure,
Shall i create any virtual directory ?
Thanks in advance,
Rizly

Hi Justin ,
Sorry for the late replay.
I am running Oracle on Windows.
The MS DOS Batch file is to convert XML file to PDF format. It is a Java Application.
also it is a batch process, thats why i created a batch file for that. I am using FOP to convert XML to PDF.
FOP is in the e:\services folder of the Database Server machiene. XML file is also in the same forlder and I need to generate the PDF file also in the same machiene.
<<- You have a client machine. What do you mean by "executing this from my PC (Client PC) directly on the RUN , its generating the PDF file in the server.">>
I have mapped the e:\services folder in my client machience, so i am accessible to the genPDF.bat file that is in the 'e:\services' folder of the DB Server. When i run the bat file from my PC as Start > Run e:\services\genPDF.bat . The PDF file has generated in the DB Server machien.
I dont have the copy of the batch file in client machiene, but i have mapped to my client machiene.
Thanks again,
Rizly

Off topic question in DOS Batch files ...

Hi,
I am sorry in advance, for posting an off-topic question. But I had no other known way.
I need to invoke 8 sessions of a java program on 8 different windows. I use Windows platform. I want to write a batch file that will cause the java program to be invoked on a separate window, so that I can watch the execution of 8 sessions at a time. How can I do this (specifically, how can I open a new window in batch files in DOS)?
Thanks in advance,
K
My java program invocation is like this:
C:\>java Site i
where i is a command line argument that will go from 0 to 7.

Batch files (to my limited knowledge) are just "macros" that procedurally run DOS commands. It's just like opening a new command window and sitting there typing a list of commands, except the computer does it for you. So, for example, to run the commands java HelloWorld and cls, the java program would first have to execute before the screen can be cleared. For your purposes, you may need a small launcher app.

Running universal installer from Dos batch file

Trying to a script an unattended install for a couple of Oracle client products (namely 9i client and Oracle Workflow Builder). My script runs the relavent setup.exe with a responsefile and silent option. This is working fine but the control is returning from setup.exe before the install has completed. The setup.exe goes on to complete ok but I have no way of controlling when to start the next install in the script. I have tried playing with BOOSTRAP=NO option in the ORAPARAMS.ini file but this does not have any effect. Any ideas anyone?

How do I make a batch file if the .class file uses a foreign package?

I am trying to make an MS-DOS batch file using the bytecode file from the Java source file, called AddFields.java. This program uses the package BreezySwing; which is not standard with the JDK. I had to download it seperately. I will come back to this batch file later.
But first, in order to prove the concept, I created a Java file called Soap.java in JCreator. It is a very simple GUI program that uses the javax.swing package; which does come with the JDK. The JDK is currently stored in the following directory: C:\Program Files\Java\jdk1.6.0_07. I have the PATH environment variable set to the 'bin' folder of the JDK. I believe that it is important that this variable stay this way because C:\Program Files\Java\jdk1.6.0_07\bin is where the file 'java.exe' and 'javac.exe' are stored. Here is my batch file so far for Soap:
@echo off
cd \acorn
set path=C:\Program Files\Java\jdk1.6.0_07\bin
set classpath=.
java Soap
pause
Before I ran this file, I compiled Soap.java in my IDE and then ran it successfully. Then I moved the .class file to the directory C:\acorn. I put NOTHING ELSE in this folder. then I told the computer where to find the file 'java.exe' which I know is needed for execution of the .class file. I put the above text in Notepad and then saved it as Soap.bat onto my desktop. When I double click on it, the command prompt comes up in a little green box for a few seconds, and then the GUI opens and says "It Works!". Now that I know the concept of batch files, I tried creating another one that used the BreezySwing package.
After I installed my JDK, I installed BreezySwing and TerminalIO which are two foreign packages that make building code much easier. I downloaded the .zip file from Lambert and Osborne called BreezySwingAndTerminalIO.zip. I extracted the files to the 'bin' folder of my JDK. Once I did this, and set the PATH environment variable to the 'bin' folder of my JDK, all BreezySwing and TerminalIO programs that I made worked. Now I wanted to make a batch file from the program AddFields.java. It is a GUI program that imports two packages, the traditional GUI javax.swing package and the foreign package BreezySwing. The user enters two numbers in two DoubleField objects and then selects one of four buttons; one for each arithmetic operation (add, subtract, multiply, or divide). Then the program displays the solution in a third DoubleField object. This program both compiles and runs successfully in JCreator. So, next I moved the .class file from the MyProjects folder that JCreator uses to C:\acorn. I put nothing else in this folder. The file Soap.class was still in there, but I did not think it would matter. Then I created the batch file:
@echo off
cd \acorn
set path=C:\Program Files\Java\jdk1.6.0_07\bin
set classpath=.
java AddFields
pause
As you can see, it is exactly the same as the one for Soap. I made this file in Notepad and called it AddFields.bat. Upon double clicking on the file, I got this error message from command prompt:
Exception in thread "main" java.lang.NoClassDefFoundError: BreezySwing/GBFrame

... 12 more
Press any key to continue . . .
I know that most of this makes no sense; but that it only means that it cannot find the class BreezySwing or GBFrame (which AddFields extends). Notice, however that it does not give an error for javax.swing. If I change the "set path..." command to anything other than the 'bin' folder of my JDK, I get this error:
'java' is not recognized as an internal or external command,
operable program or batch file.
Press any key to continue . . .
I know this means that the computer cannot find the file 'java.exe' which I believe holds all of the java.x.y.z style packages (native packages); but not BreezySwing or any other foreign packages. Remember, I do not get this error for any of the native Java packages. I decided to compare the java.x.y.z packages with BreezySwing:
I see that all of the native packages are not actually visible in the JDK's bin folder. I think that they are all stored in one of the .exe files in there because there are no .class files in the JDK's bin folder.
However, BreezySwing is different, there is no such file called "BreezySwing.exe"; there are just about 20 .class files all with names like "GBFrame.class", and "GBActionListener.class". As a last effort, I moved all of these .class files directly into the bin folder (they were originally in a seperate folder called BreezySwingAndTerminalIO). This did nothing; even with all of the files in the same folder as java.exe.
So my question is: What do I need to do to get the BreezySwing package recognized on my computer? Is there possibly a download for a file called "BreezySwing.exe" somewhere that would be similar to "java.exe" and contain all of the BreezySwing packages?

There is a lot of detail in your posts. I won't properly quote everything you put (too laborious). Instead I'll just put your words inside quotes (").
"..there are some things about the interface that I do not like."
Like +what?+ This is not a help desk, and I would appreciate you participating in this discussion by providing details of what it is about the 'interface' of webstart that you 'do not like'. They are probably misunderstandings on your part.
"Some of the .jar files I made were so dangerously corrupt, that I had to restart my computer before I could delete them."
Corrupt?! I have never once had the Java tools produce a corrupt Jar. OTOH, the 'cannot delete' problem might relate to the JRE gaining a file lock on the archive at run-time. If the file lock persisted after ending the app., it suggests that the JRE was not properly shut down. This is a bug in the code and should be fixed. Deploying as .class files will only 'hide' the problem (from casual inspection - though the Task Manager should show the orphaned 'java' process).
"I then turned to batch files for their simple structure and portability (I managed to successfully transport a java.util containing batch file from my computer to another). This was what I did:
- I created a folder called Task
- Then I copied three things into this folder: 1. The file "java.exe" from my JDK. 2. The program's .class file (Count.class). and 3. The original batch file.
- Then I moved the folder from a removable disk to the second computer's C drive (C:\Task).
- Last, I changed the code in the batch file...:"
That is the +funniest+ thing I've heard on the forums in the last 72 hours. You say that is easy?! Some points.
- editing batch files is not scalable to 100+ machines, let alone 10000+.
- The fact that Java worked on the target machine was because it was +already installed.+ Dragging the 'java.exe' onto a Windows PC which has no Java will not magically make it 'Java enabled'.
And speaking of Java on the client machine. Webstart has in-built mechanisms to ensure that the end user has the minimum required Java version to run the app. - we can also use the [deployJava.js|http://java.sun.com/javase/6/docs/technotes/guides/jweb/deployment_advice.html#deplToolkit] on the original web page, to check for minimum Java before it puts the link to download/install the app. - if the user does not have the required Java, the script should guide them through installing it.
Those nice features in deployJava.js are available to applets and apps. launched using webstart, but they are not available for (plain) Jar's or loose class files. So if 'ensuring the user has Java' is one of the requirements for your launch, you are barking up the wrong tree by deploying loose class files.
Note also that if you abandon webstart, but have your app. set up to work from a Jar, the installation process would be similar to above (though it would not need a .bat file, or editing it). This basic strategy is one way that I provide [Appleteer (as a downloadable ZIP archive)|http://pscode.org/appleteer/#download]. Though I side-step your part 1 by putting the stuff into a Jar with the path Appleteer/ - when the user expands the ZIP, the parts of the app. are already in the Appleteer directory.
Appleteer is also provided as a webstart launched application (and as an applet). Either of those are 'easier' to use than the downloadable ZIP, but I thought I would provide it in case the end user wants to save it to disk and transport the app. to a machine with no internet connection, but with Java (why they would be testing applets on a PC with no internet connection, I am not sure - but the option is there).
"I know that .jar and .exe files are out because I always get errors and I do not like their interfaces. "
What on earth are you talking about? Once the app. is on-screen, the end user would not be able to distinguish between
1) A Jar launched using a manifest.
2) A Jar launched using webstart.
3) Loose class files.
Your fixation on .bat files sounds much like the adage that 'If the only tool you have is a hammer, every job starts to look like a nail'.
Get over them, will you? +Using .bat files is not a practical way to provide a Java app. to the end user+ (and launching an app. from a .bat looks quite crappy and 'second hand' to +this+ user).
Edit 1:
The instructions for running Appleteer as a Jar are further up the page, in the [Running Appleteer: Application|http://pscode.org/appleteer/#application] section.

Running a Batch file Using Java

hi All ,
I am executing a DOS batch file using the Java .
I am using it as
Process P;
Runtime rt = Runtime.getRuntime();
P = rt.exec("C:\\X12TST\\BATCH1.BAT ");
But in case BATCH1.bat have call to some other Batch File Say Bactch2.bat , i am not getting the output of BATCH2.BAT .
My Java Program exits as soon as it enters to the point where BATCH1 is calling BATCH2 using (call BATCH2.bat).
Any help is resolving the problem is highlt appreciated .
Please advise me if you have any alternative to solve the problem .
Thanx in advace

The Runtime.exec() should'nt be used with a .bat or .cmd file since .bat and .cmd are not really executable. I think the expected behaviour you experimentred is a process hang at the last command line of the .bat file.
Insert "echo XXX" or "net send mycomputer XXX" debug messages in your .bat, you'll see the .bat executes until last line. But the last one NEVER terminates, resulting in a hang in the Java thread doing a process.waitFor().
The only workaround (or right use of exec) is to call the cmd.exe (with FULL PATH OF cmd.exe SPECIFIED in the exec() call). An exec() calling C:\WINNT\System32\cmd.exe /C mybatch.bat should return properly, cause cmd.exe is a standard Win32 program that will be launched to interpret mybatch.bat then terminate.
PLEASE UNIX/LINUX USERS : report if the behaviour you get is the same on your plat-form, or if it is -one more- bug in win32 OS. Can you exec() a shell script direcly or do you have to exec() a "bash" or "ksh" or "csh" with you shell script as command line argument ?

How can I execute a batch file from my java program

Hi,
Can someone help me or direct me to a link,
How can I execute a DOS batch file from my java program?
Thanks

You will need to grab a handle to the process's
outputstream so u can see its output.The OP didn't mention any output from any batch file;
nor any input for that
matter,so lets not complicate matters here for now
ok?Actually I think this is essential to see whether it works or not. It's either that or do some manual check to see whether it ran, which is not exactly elegant, and in some cases this may not be easier than simply writing the output stream code, or in fact it may be impossible to check manually.
I'm sure it wasn't intentional that your post appeared to be bristling with attitude.
