Context
I have a webservice writing a test id in a queue. Then, a listener reads the queue, searches the test and starts it. During those steps, it writes updates of the test in the database in order to be shown to the user. To be more precise: the test is launched in a docker container and at the end of it, I want to update the status of the test to FINISHED. For that, I use the docker java library with a callback.
Problem
When it comes to call the callback, I receive multiple error messages on the call to update the test (but it happens only once, if I try twice the second time works, but it still writes a lot of error messages from the transaction manager).
Here are the error messages logged:

Explanation
At the beginning, I thought about a connection problem, maybe the the transaction is no more available at the callback time (because the docker run took too long), maybe it has to be invalidated.
But at the end, as written in the console, it came from an interruption of the thread when it tries to acquire the lock to update the test and I discovered where this interruption came from: I took a look at the method executeAndStream in DefaultInvocationBuilder from the docker java library and I discovered this:
Thread thread = new Thread(() -> {
Thread streamingThread = Thread.currentThread();
try (DockerHttpClient.Response response = execute(request)) {
callback.onStart(() -> {
streamingThread.interrupt();
response.close();
});
sourceConsumer.accept(response);
callback.onComplete();
} catch (Exception e) {
callback.onError(e);
}
}, "docker-java-stream-" + Objects.hashCode(request));
thread.setDaemon(true);
thread.start();
And here it is, the closable given to onStart interrupts the thread. After that, I discovered in the method onComplete from ResultCallbackTemplate (that I was extending for my callback) a close on that closable:
#Override
public void onComplete() {
try {
close();
} catch (IOException e) {
throw new RuntimeException(e);
}
}
Resolution
The problem finally came from the following code I wrote:
#Override
public void onComplete() {
super.onComplete();
updateTest(FINISHED);
}
I was calling the onComplete method from the parent without knowing what is does and as usual, first before doing anything else. To correct that, I only had to call the super method at the end:
#Override
public void onComplete() {
updateTest(FINISHED);
super.onComplete();
}

Faced an issue on prod system where 1 message was left unacked for 30 mins which lead to consumer being shutdown. Now I have added shutdownlisteners as described in rabbit mq docs -
https://rabbitmq.github.io/rabbitmq-java-client/api/4.x.x/com/rabbitmq/client/ShutdownListener.html
if (cause.isHardError()) {
log.error("Connection error with cause : {}", cause);
Connection conn = (Connection) cause.getReference();
if (!cause.isInitiatedByApplication()) {
Method reason = cause.getReason();
log.error("Rabbit Mq Consumer Connection Shutdown : {} {}", reason, cause);
}
} else{
Channel ch = (Channel)cause.getReference();
log.error("Channel error details : {}", ch);
}
});
The issue is it's not getting invoked at all in testing. I tried triggering it through 2 ways-
Through unacked delivery timeout. Basically threw a general excption and never acked it(these were the original conditions of the bug). However, this didn't work.
I used channel.close() to shutdown the consumer but still didn't receive an event.
Looking for any way to replicate the issue I faced and test/trigger the shutdownlisteners. Thanks
my java code is like:
logger.info("start");
getJdbcTemplate().execute("call " + procedureName + "()");
and I got the exception:

Maybe it's caused by the long time waiting. I found that it printed "start" in log and after about 5 minutes I got the exception.

The druid's JdbcUtil.close method is quite simple:
public static void close(Connection x) {
if (x == null) {
return;
}
try {
x.close();
} catch (Exception e) {
LOG.debug("close connection error", e);
}
}
the source code is :
https://github.com/alibaba/druid/blob/master/src/main/java/com/alibaba/druid/util/JdbcUtils.java
It should wait as long as it is needed. Forget about various hacks which try to "detect" deadlock based on timeout delay.
you should find also some ORA-XXXX error. Io ERROR: Connection reset does not look like Oracle error message, there should be some error number attached to it
the timeout 5 minutes is very strange value. Theoretically this can be setup also on database side. As profile parameter CPU_PER_CALL but in such a case you should get an error: ORA-02393: exceeded call limit on CPU usage. And you connection should NOT be lost
theoretically you can also have problems which dead connection detection, but 5 minutes timeout is too short for that
another possible source can be ORA-600 error. Oracle internal error, maybe your session process crashed and therefore TCP connection was lost
you should contact your local DBAs and ask then for cooperation. They should help you better than anonymous people on the Internet forum.
Maybe it's caused by the long time waiting
No it is not caused due to that
As Java Doc says about DataAccessResourceFailureException
Data access exception thrown when a resource fails completely: for
example, if we can't connect to a database using JDBC.
Occasionally I see this exception. It affects some of the crucial business processes in the application. What could it be? Did anyone have similar error?
I use WebSphere 6 with OJDBC14 & Hibernate 3.

I'm having some error, I found this explain https://www.ibm.com/developerworks/community/forums/html/topic?id=77777777-0000-0000-0000-000014153732 .
He said: "I finally answered my own question. The problem was that my code was setting auto commit to false at the beginning of a transaction and did not set it back to true when the transaction was over. So when the code tried to execute single statements on the same connection object, they were not getting committed.".
I hope you help.
I have an application that is attempting to call a service and the other service appears to be timing out. The problem is my application does not receive any timeout exceptions, although I do see an error printed out to the console:

The client is created with these settings:
bindProvider.getRequestContext().put(com.ibm.wsspi.webservices.Constants.RESPONSE_TIMEOUT_PROPERTY , connectionProperties.getProperty(MyService.TIME_OUT));
bindProvider.getRequestContext().put(com.ibm.wsspi.webservices.Constants.CONNECTION_TIMEOUT_PROPERTY , connectionProperties.getProperty(MyService.TIME_OUT));
bindProvider.getRequestContext().put(com.ibm.wsspi.webservices.Constants.READ_TIMEOUT_PROPERTY , connectionProperties.getProperty(MyService.TIME_OUT));
MyService.TIME_OUT has a value of 20000 and I have verified that it is being set correctly.
The code that catches calls the service looks like this:
try
{
response = ((MyServicePortType) myService).doWebServiceOperation(request);
}
catch (Throwable e) //I know, catch Throwable is not very good but right now I'd be happy to catch ANYthing here!
{
log.error("Webservice reported error",e);
}
Even though I've changed my catch block to catch anything, I still don't catch any exceptions. WebSphere detects a transaction timeout, but I don't know why the application doesn't detect a timeout in the web service call. Is there something I'm missing that would cause a proper timeout exception to be thrown so that I can catch it and send the message to the application framework?
Well now I feel silly.
It seems that for WebSphere, these properties (RESPONSE_TIMEOUT_PROPERTY, CONNECTION_TIMEOUT_PROPERTY, etc...) should have their values set in seconds, and I was using milliseconds based on what I'd seen in online examples (that clearly were not intended for WebSphere).
Changing 20000 to 20 has resolved this problem.
The page that suggested I should be assuming seconds instead of milliseconds is this one: http://pic.dhe.ibm.com/infocenter/wasinfo/v7r0/index.jsp?topic=/com.ibm.websphere.express.doc/info/exp/ae/rwbs_httptransportprop.html
I'm having trouble understanding what is happening and why my loop doesn't continue. I'm creating a dashboard for all open activiti tasks. Now the trouble i am having is when someone closes a task while the dashboard is being created.
The code is like this:
List<Task> approvalTasks = taskQueryApproval.list();
for (Task task : approvalTasks) {
try {
ActivitiApplicationRequest activitiRequest = (ActivitiApplicationRequest) taskService
.getVariable(task.getId(), ACTIVITIREQUEST);
if (!dashboardValues.containsKey(activitiRequest.getGlobalRequestId())) {
GlobalRequest globalRequest = globalRequestDao
.findMinimalGlobalRequestForDashboardBySyscode(activitiRequest.getGlobalRequestId());
if (globalRequest != null) {
DashboardValueObject vo = new DashboardValueObject(globalRequest);
vo.setHasApproval(true);
dashboardValues.put(activitiRequest.getGlobalRequestId(), vo);
}
}
} catch (ActivitiException ex) {
LOGGER.debug("Approval already done, skipping activititask");
}
}
The trouble I'm having is I know when the task doesn't exist Activiti is going to throw an exception, that's why I placed a try-catch inside the for loop.
What I'm expecting is that when the error is catched it just continues with the rest of the list. While debugging I even saw the catch being done. But the loop still breaks and the application stops. With these exceptions :
