Jmap: portability and safety for snapshotted process?
I'm working on tracking down a memory leak in a java application that's at the heart of my employer's business. Right now, we're restarting it periodically, and watching it closely with nagios.
I'd like to do a jmap dump and jhat analysis of the heap while it has a lot of memory in use - but before I do, we need to answer the question: "Is there any risk to the process inspected?" Has anyone ever seen or heard of a java process getting messed up (say, writing corrupted data?) as a result of a jmap?
Another, slightly less important question is: Can I jmap on a windows machine and analyze the resulting file on a Linux machine?
Thanks!
Did you have a windows form or a web based application? Did you use LoadRunner to invoke multiple concurrent synchronization calls to move data from the lite database to the back-end database? Also, was LoadRunner executing against one instance of your application or multiple instances? Were application instances running on one machine or multiple machines? We are just trying to get a better understanding of your application/load test setup and see if it was structurally similar to ours.
We basically have a windows form based application designed for a single user. This application allows user to synchronize data from Olite to back-end Oracle database after user has completed their data entry.
We wanted to test the performance of our synchronization process. That is how many user can concurrently synchronize their data at the same time.
Given that our application is a single user application, we decided to invoke multiple instances of application on a single machine and then simultaneously try to synchronize (via a tool) each instance of the application. Hence the error.
Thanks for your feedback.

Ho to create Mass Processing and jobs for monthly process
Hi Gurus,
I had created all activities and jobs for background run and my question is 1. how to create for mass process ?
2.Do i need to create process chains for background run for every month ?
3. How to create parallel processing as well/
Please let me know and thanks for your answers.

You can use a process chain and it is much easier if you want to repeat that periodically and integrate with the process steps. You have the option of creating parallel processes in process chains as well.

Thread safety for synchronization process
We are invoking multiple instance of our
application and attempt to issue synchronization calls simultaneously in order
to perform some load testing.
Is the Oracle lite synchronization process thread safe? Does anyone have
recommendation on how to perform concurrent synchronization from the same
computer?
We recieve following exception:
System.AccessViolationException {"Attempted to read or write protected memory.
This is often an indication that other memory is corrupt."}

Macbook Pro Color Profile and Calibration for Photo processing.
Hello Friends,
May be it has already discussed in many forums but somehow I got confused about different solutions of the questions and due to this asking once again here.
I am using Macbook pro of 2012 and there exist many color profiles in the Display settings.
I am a photographer who uses Photoshop for the editing as well as Canon Software.
To get the most accurate Monitor Calibration Should I use default "color LCD" profile ?
I am not using any External Calibration tool. I have manually calibrate the screen but somehow I am not 100% confident on that.
In that case should I go for default "color LCD" for my photo processing. I found some light yellow cast/warm color on that profile but I am not sure..
Any help/suggestion will be much appreciated.
I am using:- MacBook Pro + OS X Mountain Lion 10.8.5
Warm Regards,
Ari...Which model MacBook Pro? [EDIT] my bad, didn't see it in your original post
You mentioned that there is no error message when you try to change the profile; something is probably being reported to console though. Open Console.app (in /Applications/Utilities/) and see if anything is reported to it while you're experiencing these problems. If so, please post it here and I'll take a look at it.
Are you using the default profile that came with the machine or did you create your own by using the Calibration Assistant?
You might try opening Color Sync Utility (in /Applications/Utilities/) and verify or repair (if necessary) your color profiles.
Hope this helps....

I have an ongoing series of tasks that necessitates opening the contents of a series of folders as image sequences.
I'm used to setting up some fairly complex actions, including ones that are intended to be applied to all of the contents of materials in various subfolders, but for some reason I cannot get an Open-with-Image-Sequence-Checked action to set up in a way that will batch process correctly.
Complicating matters is that the file prefixes (i.e., the letters before the sequential numbers) and the folders will always have different names from the last time the process had to be carried out.
The steps I would like the action to carry out would be the following:
1. Open Subfolder 1 - that is, Photoshop shouldn't be looking for a specific folder. It's just *any* subfolder to the current parent folder.
2. Select first file in sequenced set of files.
3. Open as an image sequence.
4. Open Subfolder 2.
5. Select first file in sequenced set of files.
6. Open as an image sequence.
...rinse and repeat until Photoshop runs out of subfolders to check.
Am I asking the impossible?
Thanks!I'll look around there, because I had posted something about this and was told to look here ps-scripts - Browse /Image Processor Pro/v3_0 at SourceForge.net
then this is the image here:
is the result I received. Granted I'm new to using scripts and actions for image processing large amounts of files. -
How to check actual allocated and used memory for java process in solaris?
Hi,
I'm testing performance for java application on solaris 10. And I would like to know how to measure actual memory allocated and used for java process.
I'm setting -Xms512m -Xmx512m for my java process and I use prstat command to monitor it's memory. But I found that when I run prstat to check, in SIZE column is more than I setting (found 644).
So I'm don't know the actual memory that java process used. (In this case,is it mean the process use memory (644) more than setting (512)?)
Thank you.With Xms/Xmx you specify the Java heap size. On top of that comes the permanent generation (default max size 64m) and the C part of the process (the JVM itself with all its libraries and data).
With "ps -e -o pid,vsz,rss,args" you get the virtual and set resident size of your processes.

I just purchased the iMac and was in the process of setting it up and it locked up, requiring me to put in a password. I never established a password, does the iMac have a default password?
If you have been using the mac.com Apple ID to make iTunes purchases recently, then there should be no issues continuing to use it with the new iPhone. I would abandon the new ID as you will never get Apple to merge the two IDs. I have had a mac.com ID for years and continue to use it with my iPhone 4S.
Tell us the issues that you encounter trying to set up the iPhone with the mac.com account. -
Partial GR and GI for Process Orders
Hello,
I have a scenario where user want to do Partial GR and GI posting against process order using PI sheet and he can very well do this.
I want to know which SAP table will store this data. I want to prepare report which will run everyday evening and get GR and GI postings done against process done.

Parshuram,
You can use standard transaction MB51 for this purpose, which would give you all the material movements for an Order/orders.
If you still need to develop a report then you need to use MSEG table to extract the data. Order details can be from AUFK/AFKO/ AFPO , planned GI quantities from RESB table

My iphone 4 is telling me I have to restore but when I plug in and connect to itunes, it freezes about 30-50 % through the process. Now I can't use my phone at all? I am waiting about 1-3 hours for this process to finish and nothing ever happens. HELP!!
Put it into DFU mode - hold the sleep/wake button and home button until the screen goes black (ignoring the slide to turn off slider). When the screen goes black release the sleep/wake button but hold the home button. Continue holding the home button for 10 seconds, then release it. The screen should stay black. Plug it into iTunes and it should come up with this message "iTunes has detected an iPhone in recovery mode. It must be restored before use", that's when it is successfully in DFU mode. Now press the restore button in iTunes and it should run smoothly :)

How to kill Forms Runaway Process using 95% CPU and running for 2 hours.
We had a situation at E-Business Suite customer (using Oracle VM server) where some of Form processes were not being cleared by form timeout settings automatically.
Also when user exits the form session from front end, the linux form process (PID) and DB session did not exit properly, so they got hung.
They were spiking CPU and memory usage and causing e-business suite to perform slowely and ultimately causing VM host to reboot the production VM guest (running on Linux).
We could see the form processes (PIDs) using almost 100% cpu with "top" command and running for a long time.
Also we verified those Form Sessions did not exist in the application itself.
ie. Using from Grid Control -> OAM-> Site Map -> Monitoring (tab) -> "Form Sessions".
It means that we could safely kill that form process from Linux using "kill -9 <PID>" command.
But that required a continuous monitoring and manual DBA intervention as customer is 24x7 customer.
So, I wrote a shell script to do the following;
• Cron job runs every half an hour 7 days a week which calls this shell script.
• Shell script runs and tries to find "top two" f60webmx processes (form sessions) using over 95% cpu with 2 minutes interval.
• If no process is found or CPU% is less than 95%, it exits and does nothing.
• If top process is found, it searches for its DB session using apps login (with hidden apps password file - /home/applmgr/.pwd).
a. If DB session is NOT found (which means form process is hung), it kills the process from unix and emails results to <[email protected]>
b. If DB session is found, it waits for 2 hours so that form process times automatically via form session timeout setting.
It also emails the SQL to check the DB session for that form process.
c. If DB session is found and it does not timeout after 2 hours,
it kills the process from unix (which in turn kills the DB session). Output is emailed.
This are the files required for this;
1. Cron job which calls the shell script looks like this;
# Kill form runaway process, using over 95% cpu having no DB session or DB session for > 2hrs
00,30 * * * * /home/applmgr/forms_runaway.sh 2>&1
2. SQL that this script calls is /home/applmgr/frm_runaway.sql and looks like;
set head off
set verify off
set feedback off
set pagesize 0
define form_client_PID = &1
select count(*) from v$session s , v$process p, FND_FORM_SESSIONS_V f where S.AUDSID=f.audsid and p.addr=s.paddr and s.process='&form_client_PID';
3. Actual shell script is /home/applmgr/forms_runaway.sh and looks like;

# Description : Kills runaway form processes using more than 95% cpu
# and Form Session with no DB session or DB session > 2hrs

If you have the same problem with some other unix and DB processes, the script can be easily modified and used.
But use this with thorough testing first (by commenting out <kill -9 $PID1> lines.
Good luck.

How could i get the kernel and user cpu usage for each process
Hi all,
In order to monitor the system CPU usage, I would like write a script to gather the kernel and user CPU usage for each process, like the prstat or top does. As always missing the shortlived kernel usage, prstat or top cann't get the precise CPU usage. I checked with the dtrace syscall, proc and fbt provider, but don't get which one is useful.
Please provide your comments and suggestion.
Thanks in advmail2sleepy wrote:
As I've studied the "dtrace" for a while, and seems Sun gives a pretty high score on this new feature.....I do want to know whether there's some probe can work for it, like writing a "dtrace" version prstat.You can write a prstat without dtrace. Because that's just polling at specific intervals and reading some process structures from /proc. You could have dtrace fire a probe every 5 seconds and read the same thing, but it wouldn't really be using any features of dtrace. Trhying to write it "in dtrace" doesn't make much sense.
What you could do that would be harder via other methods is to fire a probe at process exit that displayed the process information including total CPU time. They could print exactly when processes exited. Doing that without dtrace would be very difficult.

Custom process code and FM for custom IDoc...
Hello Experts,
I created a custom IDoc based from ARTMAS05 IDoc. This is because we only need 3 segments and
the standard idoc(Artmas05) contains so many segments that we need.
Now, will I create a custom process code and FM for this? how do I go about this?
Thank you guys and take care!Hello,
Here are the Steps that we need to be following while creating a Custom Process Code with Custom Function Module. ( Since the Segments to be handled are very Less, I am recommending that you go for a Custom Function Module).
1. Go to SE37 Create a Function Module. Please ensure to Create it with the IMPORT / EXPORT /TABLES parameters exactly in the way that they exist in any Standard SAP Inbound FM (Refer to IDOC_INPUT_ORDERS for example).
2. Once our FM is Ready (Need not be Complete with the Code to go ahead with the Process Code Creation) and Active, the next Step is to Create an Entry in the Transaction Code BD51 where we will register the Function Module.
3. Next, we'll have to go to T-Code WE57 where we'll have to make an entry for the Function Module with the IDoc Type & Message Type.
4. Finally, go to WE42 and Create a New Process Code and assign the Function Module and the Message Type.
NOTE 1 : The Process Code is, as we know, Client Dependent. So, once you create a Process Code, we need to have it migrated to the Testing Environment to Start & Carry Out Testing.
NOTE 2: If Step 2 & 3 are missing, then we'll not be able to assign the Function Module in WE42 while Creating Process Code.
Hope it was helpful.
Thanks and Regards,
