How to ignore DAQmx buffer errors ?

Hi,
In my application, I have to start the data acquisition of analog inputs (PCI 6025E)so that it could be read when the uses wishes to through a user interface VI. In addition to this, I also have a background thread that reads two of these AI ports every 250 msecs. However, by the time the buffer is read it has probably been overwritten atleast once and then it throws this error window saying buffer was overwritten etc. I think the buffer is a circular buffer and if so buffer being overwritten doesn't affect my application. So, is there a way I can avoid this error window from popping up ?
Thanks,
Sharmila

There might be a couple of ways out of this. If you create a functional global (also known as a LabVIEW2 style global)you can have it written too by your DAQ portion, and read from elsewhere. You can make this LV2 global act as a circular buffer, allowing you to read from it when ever you need to, but allowing the DAQ to write to it when ever it needs to. There has been a lot of discussion on the construction of LV2 globals, so you should be able to find the information.
Additionally, in the recent versions of LabVIEW there is an option (under the tools/option/block diagram menu pulldown) that allows enabling automatic error handling. What this does is cause an error dialog box to pop-up on any vi you use that has error handling that you haven't "handled" by wiring the error out to something else. Unchecking this may prevent the popup, I don't know whether the vi generating it will then just continue or whether it will need to have it or some earlier vi "reset". This is a useful feature, particularly in development and debugging, although I prefer to intentionally handle errors when I'm designing my code as it forces you to think about the various possible input cases that might fall outside of what you really wanted to happen.

How to ignore the material with error in costing run ck40n

Hi
Pls, advice how to ignore parent material form costing run if the components of that material have errors. I need to run the costing run excluding erroneous parent item. Is any configuration on this..
Pls help..
K

Hi Kesharika Goona...
If you want to exclude any material from Costing Run, there are two ways...
1. Go to Material Master, Costing1 view, take the check box "Do Not Cost". If you opt for this check box, the system will not consider this material for costing.
2. Where you run the standard cost estimate in CK40N, once you save you costing run with the parameters like Costing Variant etc, When you select the "Parameters" agains the Flow step of "Selection", you will be asked to give the inputs like Material Number, Plant etc.
There, against the Material Number, on the extrem right side, you will see a arrow, press that arrow, and there you can see a tab "Exclude Single Values". There you have to give the material number which you want to exclude from the costing run press "Execute" icon on the botoom-left corner of that pop-up window..
If you still face problem, pls revert back

How to ignore a DML operation using error handler.

In our streams replication application (using Oracle 10G), we have error handler to handle the errors at destination apply process. It uses straight apply process no DML handlers except error handlers. The error handler should just log the error and LCR info into the error log table and discard the DML LCR. Error logging is not a problem. But the problem is how to ignore the error DML LCR and move to next LCR in the same transaction without rollback of the transaction or any error.
Another question, do I need to use LCR.EXECUTE() procedure to continue the transaction in case of errors?
Appreciated your help.

Thanks for reference, confirmation of use of execute function.
I read those pages and other related pages in "Oracle® Streams Concepts and Administration" too.
I am able to write an error handler to handle errors with regular apply process. It is logging "no data found" errors but failing in case of foreign key violations. Error handler takes any kind of error and logs a record into errorlog table and ignores the error. I think it is not calling error handler. I checked for handlers in dba_apply_dml_handlers table. There is a handler for Inert, update and delete. I am investigating it further now. If you have any leads, please post.
Thanks for your time and help.

How to ignore SSL errors

When setting up email via secure smtp and imap there is an error because of self signed cert and i am unable to complete the setup process. I know that
the ssl cert is invalid and ready to deal with it better than leave plain text connection. How to ignore ssl errors and continue with email setup?

Hello akamit,
If I understand your question correctly, I think there is no ready solution for this situation. You could have a look at https://bugzilla.mozilla.org/show_bug.cgi?id=874346 - the discussion there may help you to understand the problem in more detail.
Kind regards.

How to resolve ORA-00001 Error in SQL Insert?

Hi all, I need your appreciated help.
I make a plsql procedure that is inserting a row according cursor value, I'm having oracle error ORA-00001: unique constraint (constraint_name) violated.
You may see this message if a duplicate entry exists at a different level: in RDBMS MySQL I have the syntax IGNORE to resolve this duplication error... and in Oracle ?
Thanks for your time and hints.

user6317803 wrote:
How to resolve ORA-00001 Error in SQL Insert?ORA-00001 means table has unique/primary key/index and you are trying to insert a row with key value that already exists in the table. I'll assume table COUNTRIES has primary key on COUNTRY_ID. Then change SQL to:
SQL = "INSERT INTO COUNTRIES(COUNTRY_ID,COUNTRY_NAME,REGION_ID) SELECT 'BZ','BLZ',3 FROM DUAL WHERE NOT EXISTS(SELECT 1 FROM COUNTRIES WHERE COUNTRY_ID = 'BZ')"There is a good chance table COUNTRIES also has unique key/index on COUNTRY_NAME. If so use:
SQL = "INSERT INTO COUNTRIES(COUNTRY_ID,COUNTRY_NAME,REGION_ID) SELECT 'BZ','BLZ',3 FROM DUAL WHERE NOT EXISTS(SELECT 1 FROM COUNTRIES WHERE COUNTRY_ID = 'BZ' OR COUNTRY_NAME = 'BLZ')"SY.

How to ignore programmatically some items during a query ?

Hi all,
The process of my application is like this : first of all the end-user enters some criteria , then he/she presses a button to search for the possible results matching the criteria entered (execute_query). The possible results are displayed through a multirecord based datablock.
The criteria screen has two parts , say part_a and part_b. When the end-user does not enter any criteria in part_b then the datasource of the results block should be a table , say data_source_1 ; and if some criteria are entered in part_b then the datasource of the results block should be a view , say data_source_2.
The datasource data_source_1 has less number of columns than the datasource data_source_2 , but all of data_source_1's columns are included into data_source_2.
So my problem is when the datasource of the results block is set to data_source_1 then there are unknown columns when executing the query (alert error). All of the columns of data_source_2 are included in the results block , and all of the columns of data_source_1 are automatically there because mathematically speaking data_source_1 is included into data_source_2.
I have tried to use in the pre-query trigger of the results block this statement : set_item_property('results_possibles.column_a',queryable,property_false); but the same error still occurs.
So how to ignore these items ?
Thank you very much indeed.

After looking at what you did to try to solve the problem, I'm not sure what the actual problem is.
You can make both datasources have the same number of columns by selecting nulls:
data_source_1: select a, b, c, null as d, null as e from <table>
data_source_2: select a, b, c, d, e from <view>
If you have a field which is used to query a column which is included in data_source_2 but not in data_source_1, and that field is populated when you run the query, then just set the block's default_where to ignore that field.
eg
data_source_1: where...and c like nvl(:control.c,'%')
data_source_2: where...and c like nvl(:control.c,'%') and d like nvl(:control.d,'%')...

Java seems to be having a buffer error....

Ok let me start by saying I do not know any JAVA programming. I just trying to fix something that some dump programmer charged me a ton of money for and it does not work right...
The program reads a XML stream and creates XML files... The read works great!!! I had someone help me figure out how to get rid of the write code to make sure the read was working and it works great. The problem exists when the files seem to happening when the files are being written... A 1mb file can take up to 8 hours to download and write to a file. But if you get rid of the write the stream can read that entire one meg in 15 seconds. So something tells me its some sort of buffer error or something like that. Here is the code...
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;
public class SocketReader
ServerSocket server = null;
Socket client = null;
BufferedReader in = null;
PrintWriter out = null;
String line;
String strTotal="";
public void listenSocket()
try {
server = new ServerSocket(9600);
catch (IOException e) {
System.out.println("Could not listen on port 9600");
System.exit(-1);
try {
client = server.accept();
catch (IOException e) {
System.out.println("Accept failed: 9600");
System.exit(-1);
try {
in = new BufferedReader(new InputStreamReader(client.getInputStream()));
out = new PrintWriter(client.getOutputStream(), true); //Getting client's output stream coz its up for grabs
catch (IOException e) {
System.out.println("Accept failed: 9600");
System.exit(-1);
int iCount=0;
int iChk=0;
try {
while ((line = in.readLine()) != null) {
System.out.println(line);
if (line != null)
iCount=line.length();
if (iCount==3){ //(line.startsWith("<?xml")){
if (iChk!=0){
//XMLWriter.writeXML(strTotal.substring(5, strTotal.length()).trim());
strTotal="";
iChk=1;
strTotal=strTotal+"\n"+line;
out.println(line);
out.flush();
//XMLWriter.writeXML(line);
//Send data back to client. Not required. Just writing back to the client coz u have his output stream!
//out.println("Received string" + line);
catch (IOException e) {
//e.printStackTrace();
System.out.println("Read failed");
System.exit(-1);
protected void finalize()
//Clean up
try {
in.close();
out.close();
server.close();
catch (IOException e) {
System.out.println("Could not close.");
System.exit(-1);
public static void main(String[] args)
SocketReader frame = new SocketReader();
frame.listenSocket();
}

A ton of money? Hopefully not too much money, as that code shouldn't have taken more than one hour to write. And it could have been done better (although consultants ALWAYS say that about the previous guy's code).
However if I start telling you what to fix, then I'm going to get into remote debugging and I really don't want to do that. Besides there's a lot of stuff in there that leads me to believe there's some strange requirements. Let me just say that a StringBuffer would have been a much more effective tool to accumulate a big string, if you want to get the original programmer back to fix the code, although that isn't going to help you as a non-programmer.

How to manage the ORA- errors

hi, can anyone tell me how to handle the ora errors, let say when a usere doesnt have the priveleges to add data in database this exception is generated:
ORA-06550: line 1, column 19: PL/SQL: ORA-01031: insufficient privileges ORA-06550: line 1, column 7: PL/SQL: SQL Statement ignored i want to display my message when this errors occure.Can i use the classes in the SRDEmo to catch the ora exceptions?
thanks in advance:)

What we did is make our own "filterOracleUserException". In this class we replace the 'default' ORA-<error>-<errortext> with our own error message which is read from a bundle:
Here is the code:
private static String filterOracleUserException(String input) {
if (input != null) {
String[] lines = input.split("[\r\n]");
if (lines.length > 0) {
Matcher m = ORACLE_USER_ERROR.matcher(lines[0]);
if (m.matches()) {
return m.group(1).trim();
m = ORACLE_ERROR.matcher(lines[0]);
if (m.matches()) {
try {
String errorCode = lines[0].substring(4,9);
return JSFUtils.getStringFromBundle("AnError.ORA." + errorCode
,input);
} catch (IndexOutOfBoundsException ex) {
return input;
return input;
good luck with it

How do I pass an error status from my java code back to the Program Job Ser

How do I pass an error status from my java code back to the Program Job Server?
I have a jar program object that reports a scheduled status of "Success" even if the java code errors out.

Exceptions thrown from the program object are ignored by the program job server.
You need to configure the Program Object, then stream out a special string sequence to the stdout of the Program Object, to set the scheduled instance status to Failed.
Look up SAP KBase 1201804 - How to programmatically set the status of a Program object to "Failed"

The time capsule though blinks amber and the Airport Utility shows blinking amber light and has a red circle with the number 1 in it.
There is an error.. probably trivial.. firmware update, default password..
Open the airport utility and find out what the error is.
Simply click the TC and see status in the summary page.. it will list all the errors and what you should do.. fix or ignore them. ie this TC has an error.. default password.. I chose to ignore.. when I "fix" the problem the LED goes green.
Here is additional TC.. it is blinking amber with faults.
Click the fault. eg default password.
You can ignore or edit .. if you click edit it will take you to the full setup where you can change the settings.
I ignored my errors and now it is green..

Synchronization of two analogue DAQmx outputs, error -89131

I am trying to synchronize two analogue waveform outputs. I can run and observe both channels in isolation but cannot work out how to run both at the same time. I'm a novice Labview user.
My system contains the following:
Labview 2012
Windows 7
PCI-6035 DAQ card
I've attempted to write code configured as MASTER/SLAVE, an error occurs when the code attempts to write the waveform to the SLAVE output (DAQmx Write), error code -89131
Any help would be much appreciated
Thanks
Duncan

Hi Duncan,
For most DAQ devices, only one hardware timed task per subsystem (i.e. analog input, analog output, digital input/ouput, ...) can run at once. Each subsystem has its own dedicated timing and triggering circuitry, and your code has two separate AO tasks trying to configure the AO subsystem's resources simultaneously. After the resources are configured the first time, the second task notices that they're already being used, and it tosses you an error indicating as much.
In order to configure multiple AO channels on a single device, you need to include both (or all) of them in a single task. For your application, since it looks like your channels will be updating at the same rate, this will be fairly straightforward.
Open the Voltage - Continuous Output example that you used as a starting point for your code.
Configure the Physical Channel(s) input -- either in the existing front panel control or as a block diagram constant -- to include both channels. You can use the dropdown, select Browse, and Ctrl-click multiple channels or you can simply type Dev1/ao0:1 into the field.
Now that the task contains two channels, it expects you to define two waveforms to write to the output. In the example, all you have to do is initialize a second element in the Waveform Settings array. Just increase the array index value to 1 to view the second entry (should be grayed out, at first) and select the Waveform Type, Frequency, or Amplitude for the waveform you want to send out on AO1.
That should get you going. Let us know if you run into any other hurdles as you develop your DAQ application!

DAQmx buffer property node not available

The following question was posted to the 'Multifunction DAQ' forum.
Since I received no respones, I'm trying it here:
I transferred an intact VI from a desktop
PC to a laptop.
On the laptop, however, the VI does not compile since the
property node "DAQmx Buffer" is not available. I suspect that I maybe
did not install the full DAQmx suite on the laptop but I don't know
which part might be missing.
(On both machines there is no DAQ hardware installed since I was just trying to do some editing.)
Is my suspicion correct? and how do I find out what's missing'?
If my suspicion is not correct: what else could it be?
TIA
Franz

If I can guess you should check which versions of daqmx are installed on both machines!

In the iTunes window, when I update my nano ipod, I get an error message "User ipod cannot be updated. The disk could not be read from or written to." How can I overcome this error message.

Hello there dilip77707,
It sounds like you are getting this error message that your iPod cannot be read from or written to when you are trying to update your iPod Nano. I recommend the troubleshooting from the following article to help you get that resolved. Its pretty straight forward, just start at the top and work your way down as needed:
'Disk cannot be read from or written to' when syncing iPod or 'Firmware update failure' error when updating or restoring iPod
Thank you for using Apple Support Communities.
