Hi,
Can we use getPrevStepLog with
Odifilemove?I tried it but iam not getting step name?
Iam trying to insert into log table.
Any help..
Cheers

HI Vas,
create a project variable eg: Prev_step and add the same variable in package with refresh , In Refreshing Tab add below query and select Work repository schema on same tab.
Datatype: Alphanumeric in Definition tab
SELECT '<%=odiRef.getPrevStepLog( "STEP_NAME" )%>' FROM dual
Note: Add this project variable after odifilemove step in package ( eg: Prev_step ----> OK ----> odifilemove )

Hello
I would like to rename a file within an ODI package.
Especially, I would use an ODI variable to set the new name of this file dynamically.
I tried this with the OdiFileMove with this syntax :
OdiFileMove "-FILE=c:/temp/sample.txt" "-TOFILE=c:/temp/#FINAN.FILE_TO_READ" "-OVERWRITE=YES" "-CASESENS=NO" "-RECURSE=YES"
where FILE_TO_READ is a variable in the FINAN project and previously set to a value.
The OdiFileMove does rename the file but it doesn't replace the name of the variable by its value.
So I got a file wich name was #FINAN.FILE_TO_READ in my c/temp directory.
Is it possible to use a variable in the TOFILE parameter ?My variable was created ans set to a value (visible in the "historic" tab) so I believed it was not necesary to "declare" it.
Reading your response, I inserted a declaration step...and it worked !
So I thank you a lot for your advise.

Hello,
I have found in the documentation that for the ODIFileMove command we can use * for generic characters in the FILE parameter but when I try to execute my command it doesn't work.
My command :
OdiFileMove -FILE=C:\poste_NPA\plz_p1_*.txt -TOFILE=C:\poste_NPA\plz_p1.txt
and the error message associated :
Warning: Could not find file C:\poste_NPA\plz_p1_*.txt to copy.
But when I put the complete name of my source file it works well and the rename occurs.
But the name of my source file is suffixed with the date so I would like to rename it everytime no matter the date.
I have try to put it in a ODI tool in a package ODIFileMove but the only difference is that in the Operator the Session succeed but my file is not renamed...
What is the problem please ?
Did someone ever use this function with the * generic characters ??
Thanks in advance
BMThanks for the input. I tried to get only 1 row at a time to process 1 file at a time. I modified the select statment as

But I am not getting any rows and getting error "Execution Query Failed". Can we use any SQL function against text file or we have any limitation? Can we also delete the row from the file after process the file(row) like we are deleting it from tables? Please comment........ -
GetPrevStepLog fails with missing parameter

gglovaHi Gglova,
Trying to help you.
Quick questions,
1. Are you using this variable in a package?
2. If so what are all the components are there in that package?
3. In the package flow where this variable comes ( i mean whether its coming after any interface/procedure or as the first step)?
Thanks,

How to Read file name which we are dealing with ODI File tool
Hi,
We are using ODi10g version and we have requirement to move file from one place to another place. We are using ODIFileMove utility but we also want to read file name.
Any help.
Thanks in Advance.You can accomplish this with a fairly simple Jython script. Use the os.listdir(<directory>) command to get the name of files in a given directory.
You can then (still in the Jython script) loop through the files and move them to a desired location (bypassing the OdiFileMove tool) OR use the Jython script to write the file names to a SQL table. Then, use an ODI procedure to loop through the newly inserted records and store the file name in an ODI variable that you can then use in your OdiFileMove tool etc.
I often refer to this blog entry from Gurcan Orhan as a starting point for this kind of task: Loading multiple files with ODI | Gurcan Orhan&#039;s Oracle Data Integrator Blog -
Please find the query below. This has to be done exclusively in ODI only no shell scripts to get the file name.
Input file name : abc_<timestamp>.txt.
Now need to read the file and capture the filename.
Read the file and move it to Archive or Error Directories based on the output
How can we achieve this with in ODI?
Please let me know your inputs as early as possible.
Thanks in Advance.Yes, it's possible.
For capturing filename you should use procedure using jython/beanshell
if the file is a source then you can use interfaces
Use the ---> for OK sucess and KO error
Use ODIFileMove utility to move the file
In order to do all these you should have understanding of using variables, models and interfaces.
For my part i have done a procedure which can monitor a directory and capture filenames as soon as file arrives , then invoke scenarios passing the filenames through variables. -
Hi Gurus,
My ODI version is: 11.1.1.5.0.
I have got a problem with OdiFileWait, which is working fine with my local files but not with the server files. However OdiFileMove is working fine with both local and server files.
Local Files:
OdiFileWait "-ACTION=DELETE" "-DIR=C:\ESP\SampleFiles" "-PATTERN=*.txt" "-CASESENS=NO" "-OVERWRITE=YES" "-FILECOUNT=1" "-TIMEOUT=1000" "-POLLINT=100" "-HEADER=0" "-KEEP_FIRST_HEADER=YES" "-NOFILE_ERROR=YES"
Server Files:
OdiFileWait "-ACTION=DELETE" "-DIR=/data/SampleFiles" "-PATTERN=*.txt" "-CASESENS=NO" "-OVERWRITE=YES" "-FILECOUNT=1" "-TIMEOUT=1000" "-POLLINT=100" "-HEADER=0" "-KEEP_FIRST_HEADER=YES" "-NOFILE_ERROR=YES"
Has anyone faced this issue before?
Any help would be really appreciated.Looks like you are hitting the issue mentioned in support note [Doc ID 1558984.1] "'ODI-30052: No file found' Signalled When Using The ODI 11g OdiFileWait Tool on a NFS Mount Directory"

Capturing Runtime Messages using getPrevStepLog ()
I am trying to create a log file (text format) with some of the properties of the getPrevStepLog () method like for example SESS_NAME, STEP_NAME, BEGIN, END, STATUS etc. And I would want to create this log for each interface. Can anyone please share the thoughts on the best way to do this in ODI?
Thanks,
Ashok.Hi Cezar,
Looks like the output log file is getting generated after the entire package is completed. Is there any way to append the file as and when an interface within the package is completed? Can we get the "Running" status of the interface? For example the log should say, interface 1 is "Done" and Interface 2 is currently "Running".
Thanks. -
I am trying to implement some kind of a server listening for requests. The listener part of the app, is a daemon thread that listens for connections and instantiates a handling daemon thread once it gets some. However, my problem is that i must be able to kill the listening thread at the user's will (say via a sto button). I have done this via the Sun's proposed way, by testing a boolean flag in the loop, which is set to false when i wish to kill the thread. The problem with this thing is the following...
Once the thread starts excecuting, it will test the flag, find it true and enter the loop. At some point it will LOCK on the server socket waiting for connection. Unless some client actually connects, it will keep on listening indefinatelly whithought ever bothering to check for the flag again (no matter how many times you set the damn thing to false).
My question is this: Is there any real, non-theoretical, applied way to stop thread in java safely?
Thank you in advance,
LeftyThis was one solution from the socket programming forum, have you tried this??
public Thread MyThread extends Thread{
boolean active = true;
public void run(){
ss.setSoTimeout(90);
while (active){
try{
serverSocket = ss.accept();
catch (SocketTimeoutException ste){
// do nothing
// interrupt thread
public void deactivate(){
active = false;
// you gotta sleep for a time longer than the
// accept() timeout to make sure that timeout is finished.
try{
sleep(91);
}catch (InterruptedException ie){
interrupt();

Understanding problem with threads
Hi,
yesterday (at least i think it was yesterday) I posted a question in this forum, I needed help with writing a multithreaded server. The answer was simple and I wrote my program. It kinda works, but there is one thing I don't understand:
I have a class, which handles the clientconnections and one that listens for incoming conections. I pass the socket returned by ServerSocket.accept() to the clientconnection object.
There is only ONE clientconnection-object. The listener just passes the socket and calls the start() method of the clientconnection object.
The clientconnection just writes some text to the client. Connecting more than one client at the same time works too. Everything works fine. And that's what I don't get. If I have only O N E clientconnection the texttransfer shouldn't work after i connect the second client, right?
But it does, is there a mistake in my logic or am I losing my sanity? :)Hi again Danbas,
Maybe you are losing your sanity... but that's ok. :)
public void startlistening(){
while(true){
try{
clientconn cc = new clientconn(ssock.accept());
}catch(IOException ie){}
//The Constructor in clientconn would look like this:
public clientconn(Socket sock){
//No idea what to do here
Every time you perform "new", you create a new object. And you are calling new every time you accept a new socket connection. So you are creating a new clientconn object each time. -
Hi all,
I would like to ask you for a help. I need to write a small program at my university. I started to write a midlet which function would be to countdown time for sports activities. I woul like to start a new thread - the one that counts down - and at the same time make the main thread sleep. After the "countdown" thread finishes, the main thread wakes up and waits for user input. The problem is that when the "countdown" thread finishes his work, I've got Uncaught exception java/lang/NullPointerException. error and the midlet halts.

Your Licznik class has a member m of type monitor, which has not been instantiated (in other words is null) hence, when calling m.put() you get NullPointerException. Please also mind, that using Thread.sleep(1000) is not an accurate way of measuring time.
If I may, please use recommended for Java class naming conventions - some of your names use lower case, while other don't which is confusing to the reader.

Problem with threads within applet
Hello,
I got an applet, inside this applet I have a singleton, inside this singleton I have a thread.
this thread is running in endless loop.
he is doing something and go to sleep on and on.
the problem is,
when I refresh my IE6 browser I see more than 1 thread.
for debug matter, I did the following things:
inside the thread, sysout every time he goes to sleep.
sysout in the singleton constructor.
sysout in the singleton destructor.
the output goes like this:
when refresh the page, the singleton constructor loading but not every refresh, sometimes I see the constructor output and sometimes I dont.
The thread inside the singleton is giving me the same output, sometime I see more than one thread at a time and sometimes I dont.
The destructor never works (no output there).
I don't understand what is going on.
someone can please shed some light?
thanks.
btw. I am working with JRE 1.1
this is very old and big applet and I can't convert it to something new.Ooops. sorry!
I did.

Problem with Threads and a static variable
I have a problem with the code below. I am yet to make sure that I understand the problem. Correct me if I am wrong please.
Code functionality:
A timer calls SetState every second. It sets the state and sets boolean variable "changed" to true. Then notifies a main process thread to check if the state changed to send a message.
The problem as far I understand is:
Assume the timer Thread calls SetState twice before the main process Thread runs. As a result, "changed" is set to true twice. However, since the main process is blocked twice during the two calls to SetState, when it runs it would have the two SetState timer threads blocked on its synchronized body. It will pass the first one, send the message and set "changed" to false since it was true. Now, it will pass the second thread, but here is the problem, "changed" is already set to false. As a result, it won't send the message even though it is supposed to.
Would you please let me know if my understanding is correct? If so, what would you propose to resolve the problem? Should I call wait some other or should I notify in a different way?
Thanks,
B.D.
Code:
private static volatile boolean bChanged = false;
private static Thread objMainProcess;
protected static void Init(){
objMainProcess = new Thread() {
public void run() {
while( objMainProcess == Thread.currentThread() ) {
GetState();
objMainProcess.setDaemon( true );
objMainProcess.start();
public static void initStatusTimer(){
if(objTimer == null)
objTimer = new javax.swing.Timer( 1000, new java.awt.event.ActionListener(){
public void actionPerformed( java.awt.event.ActionEvent evt){
SetState();
private static void SetState(){
if( objMainProcess == null ) return;
synchronized( objMainProcess ) {
bChanged = true;
try{
objMainProcess.notify();
}catch( IllegalMonitorStateException e ) {}
private static boolean GetState() {
if( objMainProcess == null ) return false;
synchronized( objMainProcess ) {
if( bChanged) {
SendMessage();
bChanged = false;
return true;
try {
objMainProcess.wait();
}catch( InterruptedException e ) {}
return false;
}Thanks DrClap for your reply. Everything you said is right. It is not easy to make them alternate since SetState() could be called from different places where the state could be anything else but a status message. Like a GREETING message for example. It is a handshaking message but not a status message.
Again as you said, There is a reason I can't call sendMessage() inside setState().
The only way I was able to do it is by having a counter of the number of notifies that have been called. Every time notify() is called a counter is incremented. Now instead of just checking if "changed" flag is true, I also check if notify counter is greater than zero. If both true, I send the message. If "changed" flag is false, I check again if the notify counter is greater than zero, I send the message. This way it works, but it is kind of a patch than a good design fix. I am yet to find a good solution.
Thanks,

Problem with threads running javaw
Hi,
Having a problem with multi thread programming using client server sockets. The program works find when starting the the application in a console using java muti.java , but when using javaw multi.java the program doesnt die and have to kill it in the task manager. The program doesnt display any of my gui error messages either when the server disconnect the client. all works find in a console. any advice on this as I havent been able to understand why this is happening? any comment would be appreciated.
troy.troy,
Try and post a minimum code sample of your app which
does not work.
When using javaw, make sure you redirect the standard
error and standard output streams to file.
Graeme.Hi Graeme,
I dont understand what you mean by redirection to file? some of my code below.

Problem with Threads and "plase wait..."-Window
Hi everyone,
I have a problem that I'm not able to solve in any way... I have a time-consuming task (a file decryption) which I execute in a separate thread; I've used the SwingWorker class, like suggested by sun-tutorial, and it works right. The problem is that I have to wait that the decryption have finished before continuing with program-execution. Therefore I would like to display a "please wait"-window while the task runs. I've tryed all the possible ways I know but the problem is always the same: the waitWindow is displayed empty, the bounds are painted but the contents no; it's only painted when the decrypt-task has finished. Please help me, I have no more resources....
decrypt-file code:
public class DecryptFile {
private String cryptedFileNameAndPath;
private ByteArrayInputStream resultStream = null;
// need for progress
private int lengthOfTask;
private int current = -1;
private String statMessage;
public DecryptFile(String encZipFileNameAndPath) {
cryptedFileNameAndPath = encZipFileNameAndPath;
//Compute length of task...
// 0 for indeterminate
lengthOfTask = 0;
public ByteArrayInputStream getDecryptedInputStream() {
return this.resultStream;
* Called from ProgressBarDemo to start the task.
public void go() {
current = -1;
final SwingWorker worker = new SwingWorker() {
public Object construct() {
return new ActualTask();
worker.start();
* Called from ProgressBarDemo to find out how much work needs
* to be done.
public int getLengthOfTask() {
return lengthOfTask;
* Called from ProgressBarDemo to find out how much has been done.
public int getCurrent() {
return current;
public void stop() {
current = lengthOfTask;
* Called from ProgressBarDemo to find out if the task has completed.
public boolean done() {
if (current >= lengthOfTask)
return true;
else
return false;
public String getMessage() {
return statMessage;
* The actual long running task. This runs in a SwingWorker thread.
class ActualTask {
ActualTask () {
current = -1;
statMessage = "";
resultStream = AIUtil.getInputStreamFromEncZip(cryptedFileNameAndPath); //here the decryption happens
current = 0;
statMessage = "";
}The code that calls decryption and displays waitWindow
final WaitSplash wS = new WaitSplash("Please wait...");
final DecryptFile cryptedTemplate = new DecryptFile (this.templateFile);
cryptedTemplate.go();
while (! cryptedTemplate.done()) {
try {
wait();
} catch (Exception e) { }
this.templateInputStream = cryptedTemplate.getDecryptedInputStream();
wS.close();Thanks, thanks, thanks in advance!
EdoardoMaybe you can try setting the priority of the long-running thread to be lower? so that the UI will be more responsive...
