Error in running Jasper Reports for more than 100 users in stress test

I have created a web application with Jasper reports. during the stress test, we were able to run the same report simultaneously for 100 concurrent users, after that we get the following error. I hope there is no problem in my code (correct me if i am wrong)
We use Web Sphere
The error we get is as follows:

if this really cannot find the file, then how could it run successfully for 100 users?
Have anyone experienced this problem?
Thanks for your help.

ummm seems odd to have 100 users making a report.. that can be the limitation of your application..

SQL connection errors when stress testing mobile service: SQL failure after 3 attempts

I have created a Mobile Service (node.js), which has been running for a few months with 50-100k api calls per day with no issues.
The usage of the service will be scaled up soon, and it will receive much higher traffic, so I am running stress tests (on a staging deployment of the same service).
The api in question queries data from the sql database that is attached to the mobile service, but caches the resulting data in a redis database for 5 minutes, so each call with identical parameters will not access the SQL database, just the redis cache.
My first test never has any problems:
Run a single api calls as fast as possible using the program wrk (https://github.com/wg/wrk). This test never has a problem, and I have run it an hour continuously with a sustained rate of 200 req/s and very few timeout errors.
The second test always causes problems:
I created a list of 5 different api calls to the same service (same endpoint, but different parameters), and I run those randomly interweaved as fast as possible. I use the program locust (http://locust.io) for this, spawing 10.000 clients at a rate of 500
per second. For the first few seconds everything goes ok, but then connections start failing massively.
I get mostly:
Error: SQL failure after 3 attempts. Error: [Microsoft][SQL Server Native Client 10.0]TCP Provider: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected
host has failed to respond.
(SqlState: 08001, Code: 10060)
And I see this in the http response:
ConnectionError(ProtocolError('Connection aborted.', gaierror(8, 'nodename nor servname provided, or not known')),)
The strange thing is that since I am running the same five calls repeatedly, only the very first of each call will actually access the sql database, every subsequent call will just return data directly from redis, and not try to access the sql database at
all.
In the azure console for the sql database in question, I see 1860 successful connections and 11 failed connections, which does not explain the massive failure rate I am seeing.

Thanks for sharing your tips on this forum, as it will be useful for other users, that run into this issue.
Feedback like this will also help us improve error reporting in the next release, as missing class files in the packaged application is a common issue when developers are moving from the embeded oc4j instance packaged with JDewveloper to standalone instances.

Please recommend a tool for stress-testing ?

Could anyone please recommend a (free) tool to do multi-threaded stress-test, on plain java classes ?
In more detail: I'd like to do unit-test for some plain java methods (only mathematical calculations. No web interface, no swing).
The emphasis is stress test: i need to launch multiple threads, all of them repeately invoking my method. Under these conditions, I need to report correctness (has the method yielded the expected return value), and statistics on response time.
Any recommendations would be appreciated . Thanks !

Working on a project that need me read data from delimited text file, the data will be converted to a tree-structure. So it's better parse the data into XML format first.What??? Why? You've got a text file and need an object tree, why do you think going to XML in between is a good idea?
Besides j2se or jdom, any fast tool for it?What do you mean with "j2se", that's not a XML handling tool (it contains several, 'though).
SAX sounds good for building object trees from XML, but there are several XML mapping libraries out there (try google).

Stress test on an HyperV server.

I have just installed my 1st HyperV server and it seems a bit sluggish.
Does Microsoft have a program to stress test the system(CPU, memory, NIC, Harddrive) and provide a report...?
Thanks,

"Copying a file" now requires context.
The management OS? Within a VM? To a VM from the Management OS?
Where are the VMs stored? Where was the file stored?
There is a large amount of context that is required to respond to your statement.
Could the addition of Hyper-V impact the time it takes to copy a file? Possibly. But this is a huge; 'it depends' type of answer.
Can you stress your server? Yes. Can you compare these results against servers without Hyper-V installed? No, not really. Everything is now different.

BIP 10g stress test

Hi everyone,
Have any one idea about how to perform an stress test to a BIP installation? Which are the KPI a customer is looking for to aprove a clustering solution?
There is any official tool from Oracle? or should I ask 20 people to run reports at the same time to see how it answer?
Thanks,
S.

You could use a product like LoadRunner for stress testing. I am not aware of an official tool from Oracle..

Database base storage stress test

Hi,
I have a ucm 11g instance up and running with SSO.
I need to test database storage against filesystem storage.
Does anyone have any suggestions on how to test this?
Also I'm sure I read somewhere (but I can't find it now) that once I go in one direction I can't go back, does anyone have any details about this?
Many thanks
James

First of all, take a look at File Store Provider (here: http://download.oracle.com/docs/cd/E14571_01/doc.1111/e10792/c02_settings005.htm#CSMSP445)
In general, filesystem storage is always used even if you store data in the database, in the end. It is, though, understood as a temporary storage. In theory, you can keep your files in both locations and I see no reason why you should not be able to go from FS to DB and back, BUT you have to consider consequences (you might have to rebuild indexes or even migrate data from one storage to the other).
As for stress tests, first you have to decide WHAT you want to test. Potential candidates are:
- checkin of a single item (wasted effort: since FS is always used as an intermediate storage it will always be a bit faster)
- mass checkin (e.g. from Batch Loader - especially if you use Fast Checkin settings, db can be a bit faster, but you will need a real lot of small files)
- search
- update (metadata - wasted effort: should be the same)
- backup
- migration of content
Then, you will have to setup two environments with more-or-less the same conditions (CPU power, memory, disk speed).
And finally, you will have to create and run you test cases. I'd suggest to automate stress tests via writing a program calling the same services with the same data. Use WebServices (if non-Java) or RIDC (if Java).
Alternatively, if your task is "to get results" rather than "perform stress tests", you could try to approach consulting services or project managers to provide some normalized results for you. Something can be obtained in this whitepaper: http://www.oracle.com/us/products/middleware/content-management/ecm-extreme-performance-wp-077977.pdf

Test report to check output devices?

Hi,
Is there a test report that will print a page so I can check if the output device is working OK and printing like it should? I have create a output device with a device type but now I would like to check if it's configured OK. Is there something I can print to check that? So resolution, margins etc.
Thanks!

Hi,
Just go to SM50 and press the printing icon there. Is not a large report but you can see the resolution and margins there.
Hope this helps you.

From the API on java.text.SimpleDateFormat
Synchronization
Date formats are not synchronized. It is recommended to create separate
format instances for each thread. If multiple threads access a format
concurrently, it must be synchronized externally. Being static, your date format object will be accessed by multiple threads.
Solution: Don't make the date format object static.
I would suggest like this:
private static final String dfString ="yyyyMMdd";
protected String formatYyyyMMddToLocaleStr(String xxxxxxxxDt, Locale locale) {
String result = "";
SimpleDateFormat xxxxxxxxDateFormat = new SimpleDateFormat(dfString );
if ( xxxxxxxxDt != null && xxxxxxxxDt.length() == 8) {
try {
    Date tempDate = xxxxxxxxDateFormat.parse( xxxxxxxxDt);
    result = javaDataTypeToString(tempDate, locale);
catch (ParseException ex) {}
          return result;
Ok, so it is constructing a DateFormatting object for each method call, but I don't see it as that big a deal. Its not a huge hit. You might get away with making it an instance variable - I don't know how you use the enclosing class. Start with this, and see if it works.

Wireless network test report says wireless radio is not functioning, c7280

Wireless does not seem to stay on. Printed a wireless network test report and it says, "The wireless radio is not functioning. Contact HP support".

Let's reset the printer - turn the printer off, hold the # and 6 keys while turning it back on.
Say thanks by clicking "Kudos" "thumbs up" in the post that helped you.
I am employed by HP

On a wireless network test report, I get "The wireless radio is not functioning."

The printer is a Photosmart C309a all-in-one. I've used this printer for some time and did so wirelessly earlier today. Upon ordering a print job the printer failed to produce results. I ran a Network Configuration Page where it showed the printer to be offline with no Active Connection Type. I then ran a Wireless Network Test report and received the message: "The wireless radio is not functioning. Contact HP Support." IS THERE A FIX FOR THIS?
I reinstalled the printer software on my computer configuring it with a USB connection, in order to be able to use the printer. I was able to use it with the USB connection but would most definitely prefer a wireless connection. I also turned off the printer, router and computer and turned them on in the order outlined in the user's manual, but to no avail. This, of course, I did before reinstalling the software for a USB connection.

Hi,
I afraid the error indicate an an hardware failure..
You may try using a wired ethernet cable as a workaround, the printer will need to be services in order to repair its wireless card.
You may find the details to contact HP support by selecting your region and following Technical Support after you buy:
