Flight Recorder does not provide Method Profiling Samples on CentOS 5

Flight recorder from jdk 1.8.0_05 does not collect information about methods then running under CentOS 5.
But jdk1.7.0_55 provides "Method Profiling Samples" events on the same machine.
Steps to reproduce:
1. Download test class - https://gist.github.com/evsinev/0b136693ef7549ddc9b5
2. compile it
3. Run it:
NOW=$(date +"%H-%M-%S")
export JAVA_OPTS="$JAVA_OPTS -XX:+UnlockCommercialFeatures -XX:+FlightRecorder"
export JAVA_OPTS="$JAVA_OPTS -XX:StartFlightRecording=duration=120s,filename=data/profile-startup-${NOW}.jfr,name=Startup,settings=profile"
export JAVA_OPTS="$JAVA_OPTS -XX:FlightRecorderOptions=samplethreads=true,stackdepth=64"
/opt/jdk1.8.0_05/bin/java $JAVA_OPTS -cp . Test
Running with jdk 1.8.0_05 does not provide "Method Profiling Samples"
Running with jdk 1.7.0_55 provides "Method Profiling Samples"
Environment:
CentOS release 5.9 (Final)
uname:Linux 2.6.18-348.1.1.el5 #1 SMP Tue Jan 22 16:19:19 EST 2013 x86_64
libc:glibc 2.5 NPTL 2.5

I've spoken to the developers of the JVM/JDK parts of JFR, and I'm afraid they say this is a known issue
(https://bugs.openjdk.java.net/browse/JDK-8036090, https://bugs.openjdk.java.net/browse/JDK-8037340)
that happens on Linux only.
It will be fixed in 7u60 and 8u20 which will be released later this year.

Retrieving "Method Profiling Sample" event duration

Hello,
I am trying to understand how JMC calculates the Percentage in Hot Methods (which according to documentation is total time that the application spent on executing code in the method), but the duration I retrieve seem to be always zero and start and end timestamps are the same. The way I am trying to do it follow below:
FlightRecording recording = FlightRecordingLoader.loadFile(new File("jfr file path"));
IView view = recording.createView();
Map <String, IEventType> eventTypes = new HashMap<String, IEventType>();
for (IEvent event : view) {
     eventTypes.put(event.getEventType().getName(), event.getEventType());
view.setEventTypes(Arrays.asList(eventTypes.get("Method Profiling Sample")));
for (IEvent event : view) {
     System.out.println(event.getValue("(duration)") + " " + ((FLRMethod)event.getValue("((stackTrace).method)")).getMethodName());
Any clarification is highly appreciated!
Thanks in advance.

The Method Profiling Samples do not have a duration,
they are taken at interval of for example 20 ms, where a predefined number of threads are sampled.
All threads cannot be sampled, for example the ones that are executing native code.
It's really "the percentage of the total number of samples that were taken in this method", which can be seen as an approximation of what the help says "The percentage of total time that the application spent on executing code in the method."
To get this we group together all the samples with the same top frame, there is not one single sample for each method with a total duration for that method.
If you look at the Events/Log, and only enable Java Virtual Machine/Profiling/Method Profiling Sample in the event types view, you will be able to see what kind of data you get.

Where to put my customized formatting that Control Hints does not provide?

To whom that know or have experience with it:
The control hints does not provide solutions for all possible formatting needs. For example, I need to display only last four digits of social security numbers (i.e., for "123-45-6789", display "***-**-6789"). Another data table column stores school semesters as YYYYMM, e.g., 200902, where 2009 is the year and 02 is the month that represents Spring (MM can also be 06 and 09 that represent Summer and Fall). I need to display the semester in a more user-friendly way (i.e., for "200902", display "Spring 2009"). Of course, I can not change data format in the table; I only seek to format the display of the data.
I would think that it takes only a few lines of java code to do these formatting by splitting the string into sub-strings, replace some of them with appropriate new values, then re-assemble them. But where to put such code? Does any documentation cover this topic?

Shay,
I read the document, tried it, and it worked out nicely.
There is not the getAttributeName() method in the ViewObjectImpl class in version 10.1.3.4, which is the version I am using. But the EO class has it and it works out all the same.
I don't know how long it would otherwise take me to read and fumble to find out where to put the custom formatting code. Your experience and familiarity with the technology really saved me a huge amount of time. Thank you so much for your help!

Purchase info record does not exists in purchase organization 1000

Hi experts,
          I have created a new enterprise structure in SAP. when i am creating a PO its picking the correct info record, but when i am doing GR, its giving the error as 'purchase info record does not exists in purchase organization 1000". I have maintained everything perfect. the only thing i have changed is I have moved the open and close period from 11-2002 to 12-2008 in MMPV.
         Please give me some suggestions, where it can go wrong.
Thanks & Regards,
Poorna.

Hi Guys,
          Thanks for all yours responses, Actually what deepak said was right, but in my IDES system i am not able to create new entries in assign plant to std purchase org. I found the database view for that, V_001W_E its for table T001W. So i looked into that table i found that std purchase org was given as 1000. i made direct entries in that table, i thought the reason for this may be due to , that i copied plant from 1000. After making entries , i did not got the error message that was i am previously getting.
Thanks & Regards,
Ravi.

File's Owner does not show methods in Interface Builder 3.2.6 but the class is set correctly and the nib on the lower left is green

Hi, I'm trying to make my first IPhone app. After having problems with interface builder the first time I coppied the code directly from a tutorial in case I made any mistakes. I saved the program, and re-opened the .xib file. Right clicking File's Owner does not show a list of methods. I've been looking around for solutions for this but have not gotten anything to work. I tried deleting the default .xib and creating a new one through file-> new file. This did not help. I did notice that File's owner was showing up as a light blue cube apposed to a yellow one now and found that a bit odd but otherwise nothing changed. I opened the library menu and selected helloWorldiPhoneViewController so it would show up in the view port. I set the class field of File's Owner to hellowWorldiPhoneViewController. File's Owner still does not show methods when right clicked or when a line is dragged over a button. I read somewhere that the color of nib on the lower left of the viewport may indicate a problem, but it is green not indicating any issue. Every solution I found for someone else seems nto to work for me and I don't know how to continue.
here is the .h file just in case:
// HelloWorldViewController.h
// HelloWorld
// Created by Paul Peelen on 2011-03-14.
// Copyright 2011 9697271014. All rights reserved.
#import <UIKit/UIKit.h>
@interface HelloWorldViewController : UIViewController {
UILabel *textLabel;
@property (nonatomic, retain) IBOutlet UILabel *textLabel;
- (IBAction)changeTheTextOfTheLabel;
@end
I'm trying to connect changeTheTextOfTheLabel to a button and textLabel to a label

You need a parameter for an interface builder method. The type should be id and the name is typically "sender". It would look like this:
- (IBAction)changeTheTextOfTheLabel: (id) sender;
Be careful about those tutorials. Many are ancient and do not correspond to current Xcode behaviour.

InvalidRecordException: Input record does not have a valid Id.

I am trying to export data from hybris to endeca. I have set up the index schema, index element, cas config, added properties.
I have added queries the index elements but somehow the recordstore are not exporting the data to endeca. When, I checked the recordstore for data, it returned an empty file. I have checked the record store config for data and it shows record.spec available. Not sure why I am getting the InvalidRecordException.

This was due to the dropping of recordstores which were not getting recreated. Using environment parameters (host and port) on the command line to create the recordstore for data resolved the issue.

Record does not "check in" after workflow is complete

Hi All,
I have built a very simple workflow as below
1. start step
2. process step
3. approve step
4. stop step
in the fourth step that is the stop step i have selected "check in" so that the record automatically check's in after the process is complete,
but the record does not check in and the data manager shows it as in workflow. please help
Thanks in Advance
Sharma.

Hello Abhishek,
Thanks for the reply.
The issue is resolved.
The user had the authorizations and the records were checked out as well.
i was missing the step of "Mark as approved" that was the reason for the records not to check in automatically.
Thanky you again.
Regards,
Sharma

When starting up Mail 7.3 does not provide a New Message window

When starting up Mail 7.3 does not provide a New Message window as it always used to? Have I inadvertently turned something off?

OOPs! My mistake; I meant New Viewer Window!
The problem is that if I close the Mail window but leave Mail running in the background, the next time I click on Mail in the Dock, I do NOT get the New Viewer Window, just the Mail Menu on the Menu Bar. If I Quit Mail in that state and then start it up from the Dock, I also get on the Mail Menu.
If, however, I Quit Mail when the Viewer Window is open, it will open up again with the New Viewer Window visible.
In the past, I got the New Viewer Window whenever I clicked Mail in the Dock.
Changing settings in System Preferences / General doesn't make any difference.
Not a huge problem, just an annoyance. Ran Permissions Repair; no change in the issue.
Thanks for your response / attempt to help. Sorry again for the mistaken Window name.

How do I compress a file on a Mac. I do not see and option to compress a file when I right click on it and the Apple help does not provide and accurate answer

Select the file with one click, then go to File in the menu bar and select Compress...
By the way Niel's post says control - click. This means click with the control key held down. It produces the same result as going to File in the menu bar and selecting Compress...

I have an Apple Configurator install that wont recognize an iPad when I attach it via USB. I cant prepare it or refresh it. It was supervised. I get an error message that says "policy does not have correct profile data". Please help!!!

I have an Apple Configurator install that wont recognize an iPad when I attach it via USB. I cant prepare it or refresh it. It was supervised. I get an error message that says "policy does not have correct profile data". At some point there was a mismatch between the profile on the iPad and the MAC server. The profile on the MAC server has been deleted and the iPad has been erased and reset to default. I need to be able to get Configurator to recognize this device to prepare it for deployment and issue Apps to it. Please help!!

Run the application 'Terminal.app' which you will find in '/Applications/Utilities' on your Macintosh.
Type this into it: defaults delete com.apple.configurator PreprationSavedPolicyDefaultsKey
Hit the return key.
If you get no error message, it worked, and you can quit the app.
