Concurrently write and read caused program hang infinitely.
Hi, everyone
I used BDB XML 2.4.11
os : windows xp service pack 2
I have set the java option -Xms64M -Xmx256M
I used a util class for retrieving the XmlManager and XmlContainer handle, the code is below
import java.io.File;
import java.io.FileNotFoundException;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;

public class BdbXmlUtil {
private static Map<String, XmlContainer> openedContainer = new HashMap<String, XmlContainer>();
private static XmlManager xmlManager = null;
public static synchronized XmlManager getXmlManager() {
if (xmlManager == null) {
EnvironmentConfig envConf = new EnvironmentConfig();
envConf.setAllowCreate(true);
envConf.setInitializeCache(true);
envConf.setInitializeLocking(true);
envConf.setInitializeLogging(true);
envConf.setRunRecovery(true);
envConf.setTransactional(true);
envConf.setLockDetectMode(LockDetectMode.MINWRITE);
envConf.setCacheSize(256 * 1024 * 1024);
envConf.setTxnMaxActive(5000);
envConf.setMultiversion(true);
envConf.setTemporaryDirectory(new File("E:/temp/bdb-xml/tmp"));
envConf.setErrorStream(System.err);
// for performance
// The setTxnNoWait has to set ture, only the transaction set true will not take effect.
envConf.setTxnNoSync(true);
//envConf.setTxnNoWait(true);
Environment environment = null;
try {
environment = new Environment(new File("E:/temp/bdb-xml/bdb_xml_testenv"), envConf);
CheckpointConfig checkpointConf = new CheckpointConfig();
checkpointConf.setKBytes(1024);
environment.checkpoint(checkpointConf);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (DatabaseException e) {
e.printStackTrace();
XmlManagerConfig managerConfig = new XmlManagerConfig();
managerConfig.setAdoptEnvironment(true);
try {
xmlManager = new XmlManager(environment, managerConfig);
} catch (XmlException e) {
e.printStackTrace();
return xmlManager;
public static synchronized XmlContainer getXmlContainer(String xmlContainerName) {
XmlContainer xmlContainer = null;
if (openedContainer.containsKey(xmlContainerName)) {
xmlContainer =
(XmlContainer) openedContainer.get(xmlContainerName);
} else {
XmlContainerConfig containerConf = new XmlContainerConfig();
containerConf.setTransactional(true);
containerConf.setAllowCreate(true);
containerConf.setNodeContainer(false);
containerConf.setMultiversion(true);
/*containerConf.setReadUncommitted(true);*/
try {
xmlContainer =
xmlManager.openContainer(
xmlContainerName, containerConf);
} catch (XmlException e) {
e.printStackTrace();
openedContainer.put(xmlContainerName, xmlContainer);
return xmlContainer;
public static synchronized void closeEnv() {
try {
Iterator<String> containerNames = openedContainer.keySet().iterator();
while (containerNames.hasNext()) {
XmlContainer container = openedContainer.get(containerNames.next());
container.close();
if (xmlManager != null) {
xmlManager.close();
} catch (Exception e) {
e.printStackTrace();
}I used two classes to test the concurrency, one is responsible for put document to database, and the other is used to query database while the put operation is being performed. The run method of the two classes is below:
put document process code:
boolean retry = true;
int retry_count = 0;
// while loop is used for deadlock retries
while (retry) {
XmlTransaction txn = null;
try {
XmlUpdateContext context = xmlManager.createUpdateContext();
TransactionConfig tc = new TransactionConfig();
tc.setNoSync(true);
txn = xmlManager.createTransaction(null, tc);
String doc = generateId() + ".xml";
xmlContainer.putDocument(txn, doc, "<user><name>hello world</name></user>", context);
txn.commit();
txn = null;
System.out.println("created : " + doc);
retry = false;
} catch (XmlException xe) {
retry = false;
if (xe.getDatabaseException() instanceof DeadlockException) {
System.out.println(getName()
+ " got deadlock exception!");
if (retry_count < 20) {
System.err.println(getName() + " : Retrying operation.");
retry = true;
retry_count++;
try {
Thread.sleep(100);
} catch (InterruptedException e) {}
} else {
System.err.println(getName()
+ " : out of retries. Giving up.");
} else {
System.err.println("XmlException during concurrent-test: "
+ xe.getMessage());
} finally {
if (txn != null) {
try {
txn.abort();
} catch (Exception e) {
System.err.println("Error aborting txn in concurrent-test: "
+ e.toString());
e.printStackTrace();
}the query process code :
XmlManager xmlManager = BdbXmlUtil.getXmlManager();
XmlResults res = null;
XmlQueryExpression expr = null;
XmlTransaction txn = null;
try {
BdbXmlUtil.getXmlContainer("entry.dbxml");
XmlQueryContext qc = xmlManager.createQueryContext();
expr = xmlManager.prepare("doc('dbxml:/entry.dbxml/1.xml')//user/name", qc);
TransactionConfig tc = new TransactionConfig();
tc.setSnapshot(true);
txn = xmlManager.createTransaction(null, tc);
res = expr.execute(txn, qc);
System.out.println("The query, '" + expr.getQuery() +
"'\n\t returned " + res.size() + " result(s)");
while (res.hasNext()) {
XmlValue value = res.next();
System.out.println(value.asString());
txn.commit();
txn = null;
increaseInvokeCount();
} catch (XmlException e) {
e.printStackTrace();
} finally {
if (res != null) {
res.delete();
if (expr != null) {
expr.delete();
if (txn != null) {
try {
txn.abort();
} catch (Exception e) {
System.err.println("Error aborting txn in query test: "
+ e.toString());
e.printStackTrace();
}in the main class, I have generated 100 threads to run the put document process and 30 threads to run the query process. After insert several documents to database, the whole process hangs infinitely. I think it is caused by the query process. When i set the query thread number to 1 or disable the query process, the put document process ended with success.
I think it is caused by the lock. I try to execute the query in Snapshot isolation, but it doesn't works. I also tried the No Wait On Blocks, it seem ok, but alway throws DeadLockException, which can not bear. I doubt about that the lock granularity is per page, and in my program I used the Wholedoc Containers. The Query Process just take action in one document, which is 1.xml, but the lock seem that the whole container is locked. Could it be the page is so large that it covers the whole container? I referenced the document Getting Started with Transaction Processing For Java, but find no hint.
The BDB XML is excellent in performance, and I want use it in my program. I really hope that this problem can be solved. I don't know whether it is a bug or my reason.Any suggestion will be very helpful, thanks advance.

Dear gmfeinberg,
You are so kind. I appreciate very much for your approval. You are alway very warm-hearted to help others. Thanks very much.
I followed your advice and changed the prepare() to add the transaction as a parameter. The complete code I have already posted above. But unfortunately the program hangs also. The complete output of the db_stat -CA when the hang happens is below:

Closing a serial port after executing a for loop of write and reads.
Hello,
Labview is opening and then closing each write to the port. I have tried to leave the close outside of the for loop, but labview wont allow it. What do I need to change to make all the writes and reads execute on 1 open and close of the serial port.?
Thanks.

The program that you posted looks to be ok for the most part, you might consider putting an open after your configure (but that's trivial). The other thing that is a minor issue is the loop tunnel coming out of your for loop is currently being auto-indexed. This function is used to index data for each interation of the loop. You are using a static address (not an array) and so you don't need this. If you right-click and remove the auto-index the broken wire will go away. Other than that it should be ok.
I would suggest looking at one of the shipping examples that come with LabVIEW. "Basic Serial Read and Write" is essentially the same thing that you are doing and is tested here and might save you a bit of time. Anyway, take a look if you have a second. Best of luck with your application!

How can i write and read the same data
hi,
i have attached my program to this mail. i have some problems in this program.
problems:
1. I want to select the threshold for the rms,varience and s.d.
But what i used is not doing that. i want to fix the upper threshold value and lower threshold value.
when ever the input crosses upper threshold value i want the output and it will remains uptill the value above the lower threshold value.
Once it come down the lower threshold value the output should be stopped.
2. I want to write this in to a file and i want to read this file. is this possible or not.
please try to help me i am very new with lab view6i

dileep.vi 93 KBThe easiest way to perform a certain action (such as file I/O) based on a certain condition (such as whether a value has passed a certain threshold) is to use a comparison VI in combination with a case structure. Then you can specify that if your rms, standard deviation and variance are above a threshold then perform a certain action.
Also consider using shift registers to keep track of data from the last loop. If I understand you correctly, you want to start logging data when an upper threshold has been passed. Then you want to continue logging data until a lower threshold is passed. I have attached a non-functional but explanatory VI that will help explain how to implement logic to that effect. It also demonstrates that you can indeed write and read from the same file in a loop. The best way to do this is to open the file before the loop, do all the necessary writing and reading in the loop, and then close the file after the loop.
Hope this helps!

DAQmxWriteCtrFreq (taskHandle1, 0, 1, 10.0, DAQmx_Val_GroupByChannel, &freq, &duty, &writtenVal, 0);
and
DAQmxReadCounterScalarF64(taskHandle2,10.0,&dataVal,0);
what i'm trying to do is to write to ctt0 and to read from ctr7 ( they are crossed in the card )
i'm having a bit problems with that can some one give me a tip on how to do it properly ?
just write freq to ctr0 and read freq from ctr7.....

Go to Solution.You should have the following sample installed on your PC that may help you in this task: DigPulseTrain-Cont.prj (it could be located in \program files\National Instruments\CVIx\samples\daqmx\counter\generate pulse folder)
Proud to use LW/CVI from 3.1 on.

DAQ vi to perform digital write and read measurements using 32 bits binary data saved in a file
Hi
DAQ vi to perform digital write and read measurements using 32 bits binary data saved in a file
Two main
sections:
1)
Perform
write and read operations to and fro different spread sheet files, such that
each file have a single row of 32bits different binary data (analogous to 1D
array) where the left most bit is the MSB. I don’t want to manually enter the
32 bits binary data, I want the data written or read just by opening a file
name saves with the intended data.
2)
And
by using test patterns implemented using the digital pattern generator or build digital data functions or otherwise, I need to
ensure that the
binary data written to a spreadsheet file or any supported file type
then through the NI-USB 6509 is same as the data read.
I’m aware I can’t use the simulated
device to read data written to any port but if the write part of the vi works I
‘m sure the read part will work on the physical device which I’ll buy later.
My Plan
of action
I’ve
created a basic write/read file task and a write/read DAQ task for NI USB 6509
and both combine in a while loop to form a progress VI which I’m confuse of how
to proceed with the implementation.
My
greatest problem is to link both together with the correct functions or operators
such that there are no syntax/execution errors and thus achieve my intended
result.
This
project is one of my many assignments for my master thesis, so please i’ll
appreciate every help as I’m not really efficient with LabVIEW programming but
I prefer it because is fun and interesting if I get to know it.
Currently I’m
practicing with LabVIEW 8.6/NI DAQmx 8.8 Demo versions and NI USB 6509
simulated device.
Please see
the attached file for my novice progress, thanks in
advance for the support
Rgds

my daughter is a college student. she needs to write and compile c programs on her mac for a class this semester. what is the best place for her to start to get the correct compiler etc. to use ? thanks
If you know that you will not be asked to design GUI interfaces, and the C programming course will adhere to command line compilation environments, then get the Xcode command-line developer tools, and skip the extra complication of Xcode until you absolutely need it. Apple has kicked GNU C to the curb and is rightly so, using Clang/LLVM compiler technology.
Sign up for a free Apple Developer account using your Apple ID, and then visit the Mac Dev Center, and towards the bottom of the page, you will see additional downloads. Click on the associated, all down loads link. Know your OS X version beforehand, as the command-line tool releases are tied to general operating system versions, and the most recent Xcode version. That said, there are currently two March 9, 2015 command-line tools for Xcode 6.2 — one for OS X 10.9 Mavericks, and the other for OS X Yosemite. -
How to combine both DAQ AI signal, write and read file in single VI
Hi
I am the new user of LabVIEW version 7.1 for testing automation application. I have to measure 33 signals ( mostly analog like temp, pressure, etc...) from NI USB 6210 DAQ system and write in master file for future verfication.From real data or from master file back up have to write one more file if only the signal reaches steady state , which will used for analysis and same signals to be read from this file parallely & make a waveform and/or table display format.
Pl. help me to shortout this problem
note: I have plan to ugrade labVIEW version 2011 shortly, so let me know doing parrel acquistion write and read file for data analysis in same VI in version 7.1......Parallel operations in LabVIEW are very simple. Just code it in parallel and it will work.
Try taking a look at some of the examples in the NI Example Finder (Help > Find Examples). There you will find example for writing to and reading from files, as well as data acquistion in parallel with other operations.
You might need a producer/consumer architecture is you are acquiring data very quickly.

Options for having cFP write and read file
I have a cFP VI that runs on a cFP 2110 controller for doing process automation on a custom piece of equipment. It seems that each month we use the same equipment for a slightly different automated process routine. What I have done in the past is to make a copy of my VI's and real-time project and then make the changes in the code for the new process. Most of the changes to the code between processes are just changes to numeric controllers to change ramp and slope times or the number of times the code repeats a set of steps. I have been playing around with writing a sort of configurations page to my VI to allow the user to change some numeric controls, save them to a file using the Read Key.VI and Write Key.VI. In the simple tests I have done, this works If I have a target VI on the cFP 2110 and a host VI where I can have the configurations page and save the file to my computer's hard drive.
The configurations file I would create would probably have 15-30 numeric controls and maybe some string commands. I have a couple of questions about doing this. Do I need to go back and create both Target and Host VI and communicate between the two using shared variables, or can I just keep my current VI and write a subVI that would save my files to the cFP controller? If I save the files to the cFP controller, can user set the numeric controller and save the file and/or likewise call-up any of say one of say 10 differnet files to populate the various sub-VI and run?
Finally, provided that I can write and read these small configuration numeric controller files to the controller, is there any advantage to writing the files to one method or the other: writing to the controller vs, creating a target and host VI to load the data?
Thank you for the help.

Test read write key.vi 58 KBStepanieO,
I finally had a change to play around with the cFP file write and read again. I was able to write a the cFP and read the file back using write to spreadsheet and read from spreadsheet. The one problem I can't seem to figure out is how you browse the cFP to select a file. If I enter the file name and path into the string command it works. But If I try to browse the cFP, the browse button only shows the computer hard drives. Is there a way to browse the cFP controller for a specific file?
Thank you for the help.

How to write and read Japanese on my Nokia E5
I am trying to find out how I can write and read Japanese on my Nokia E5.
I even don't knwo if it's possible...
Does anyone have the answer???Hello ikokitakun,
I believe you have to load a version of software on your phone that has the Japanese language pack in it because the version of software on the phone only has the languages for the region that you bought the phone in. for example if i bought my phone in NZ it would have English, Malaysian and maybe Philippino. There are "dodgey" places you can go to get the software changed but if you do this you void your warranty so be careful. Nokia doesn't condone the changing of regional software.
Hope this helps
-Cheers

How to write and read data in a specific memory location ??
Hi Everyone:
Does anyone know how to write and read data in a specific memory location by using Java ?
I need pointers, but I don't know how to do it ??

RodgerHi Everyone:

Thanks for answering
RodgerWith Java you cannot write to a specific memory location. Java does not have pointers. If you really want to do it, you need to use JNI, i.e write the required functions in C (or other languages that support pointers) and make those functions available to Java (through JNI). This approach is not portable. You can have a look at http://java.sun.com/docs/books/tutorial/native1.1/index.html

How to write and read array on ObjectOutputStream............??
Hello All...........,
I have done some code for applet and servlet communication in which i writes "String " as an object and gets reply from servlet as a string as follows:
// send data to the servlet
String input="hello there.....";
URLConnection con = getServletConnection();
OutputStream outstream = con.getOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(outstream);
oos.writeObject(input);
oos.flush();
oos.close();
// receive result from servlet
InputStream instr = con.getInputStream();
ObjectInputStream inputFromServlet = new ObjectInputStream(instr);
String result =(String) inputFromServlet.readObject();
outputField.setText(result);
//outputField.setText("good morning");
inputFromServlet.close();
instr.close();This code is same at servlet end.
But now i want to pass an int array.How to pass int[] as an object.
It is giving me error if i pass int array as int array[]={1,2,3}; oos.writeObject(array); Why is it so?
Can anybody tell me how to write and read int array[].
Thanks.
Shraddha.hello kaj,
I am trying to write as follows
while writting:
int array[]={1,2,3,4,5};
URLConnection con = getServletConnection();
OutputStream outstream = con.getOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(outstream);
oos.writeObject(array);
oos.flush();
oos.close();
while reading:
InputStream instr = con.getInputStream();
ObjectInputStream inputFromServlet = new ObjectInputStream(instr);
int result[] =(int []) inputFromServlet.readObject();
Thanks,

No, the iPad doesn't work that way. The only thing you can access is camera cards (with the adaptor).

Interruptions when I use "Write" and "Read" in the same vi.
When I use "Port Write" and "Port Read" together in the same vi and I set the output to be high level, the signal becomes oscillatory. I have read one anterior message about similar problem (using "Write to Digital Line" and "Read from Digital Line" instead of "Port Write" and "Port Read") and I proceeded as the solution suggested in the answer. However, it didn´t work.
Attached, I am sending the vi I used to test the solution.
How can I fix this problem?

IO.vi 35 KBHi Spencer!
The device I am using is a PCI6024-E board. I have contacted the NI Suport and now I see what I was doing wrong: in fact, I was calling a DIO Port Config.vi for each of the ports ("Port Read" and "Port "Write"), but it was done inside of a While loop (usually, most of the applications here in the lab are recursive, so it´s common for us to use big while loops for the whole program). Putting them outside (as you said, at the beginning of the program), it worked! Actually, I can´t see any reason for the program to work when the calling is outside the loop, but the important is that now it´s running properly.
Thanks a lot, Spencer! -
Should I use DB_INIT_CDB while open DB_ENV(multiple writer and reader)?
My version is db-4.7.25.NC
I want to use BDB as backend for BBS, so multiple writer and multiple reader are not avoidable.
My question is what flags I should select while open DB_ENV and DB, DB_THREAD or else?
DB_INIT_CDB can support only writer thread, I wonder it could meet my requirement?
Any suggestion, welcom!
Edited by: user11335524 on Jun 30, 2009 11:37 PMThe <tt>DB_INIT_CDB</tt> flag only permits one writer <i>at a time</i>. Berkeley DB uses locking internally to enforce this constraint, so if two application threads try to update at the same time, one of them will wait for the other. The <tt>DB_THREAD</tt> flag is required if multiple threads will share the same <tt>DB_ENV</tt> or <tt>DB</tt> handle.
