How can I get the memory allocation info of a java thread?
Now I am going to write a program to monitor the execution condition of the java threads. But it seems that the classes in standard edition of JDK does not provide facilities to get the information such as the memory allocation and CPU time of a running thread. How can I do with it? Can I use JNI or JVMDI to get them? If it could do, how?
Thanks a lot. I just browsed the specification of jvmpi. It is interesting and it seems that I can get the information I need. However, if I want to get the information in my program, I mean, if I want to build a class which may use JNI method to invoke the function written with JVMPI, and then forward the data to other upper layer objects, can it be done?

How can I get the orclownerguid (unique user number) in Java Portlet?

How can I get the orclownerguid in Java Portlet with JPDK?

jerome laforgeHello,
I just realized that I missunderstood your question.
We have several way to pass (and send) parameter to a portlet:
- OracleAS Portal page parameters that allow the browser user to define the way the parameter is send to the portlet
- generic URL parameter (public parameters)
- private paramter (a parameter that is targetted to a single portlet instance)
In you case, you can use public parameter, but you have to explicitly says that your portlet consume URL parameters, so set the passAllUrlParams tag to true in the provider.xml file.
Also I invite you to read the sample we have in the PDK that show how to use private parameter and page/portlet parameters, and the associated articles you can find on http://portalstudio.oracle.com

Hi how can i know the memory allocation of occurs 10 or 100
hii
experts,
how can i know how much memory is being allocated for for occurs n(10 ,100)
for an internal table declaration.is there any tcode to know that??
plz help.
thank youHi,
welcome to sdn,
Occurs 10 means the internal table allocates space for 10 rows initially....after filling these rows it allocates for the next 10 lines...similarly occurs 100.
But if you give occurs 0 ,the internal table allocates 8kb space initially...
these are the major difference....i think you can check the memory allocation of the internal table in the debugging mode instead of using a separate transaction...

I have made a burn folder with photos exported from I-photo. It now shows in information, that the date created and modified is different from the original digitized date. How can I get the original date to show in the info from Finder?
The Finder reports File information. The date and time of the photo are in the Photo's Exif metadata. The Finder has no awareness of this. All photos apps on any system do.

my computer crashed and I no longer have the itunes library. i get an error msg that my iphone 3g is synced to another library - how can I get the info from the phone to the itunes library without losing everything? How do I delete old audiobooks from my iphone?
You can transfer itunes purchases: File>Devices>Transfer Purchases
The iphone is not a storage/backup device. The sync is one way - computer to iphone. The exception is itunes purchases.
It has always been very basic to always maintain a backup copy of your computer. Use your backup copy to put everything back. -
found an locked iphone5c, how can i get the owners info, email or anything if he/she only says "pls. bring back my phone.. godbless" on the activation menu??
Try using Siri and ask "Who's phone is this?" It should give you the name, number, and email address of the owner. Also, you can try swiping to unlock, select Emergency, then see if they have a Medical ID set up. If they do, they may have the name of a contact with a phone number listed.

how can i get the info off of an old appleworks database. to my new mountain lion. OS X? My old data base is on AppleWorks 6
1. Read Roger Wilmut's excellent series of articles Abandoning Appleworks, especially the one on databases.
2. Call the Apple Store and order Snow Leopard Server for $19.99 + sales tax & shipping: 1.800.MYAPPLE (1.800.692.7753) - Apple Part Number: MC588Z/A (telephone orders only).
3. Install Snow Leopard Server into Parallels 8, now available for a short time (4 more days) in the March 2013 MacUpdate 10 App Bundle for $49.99:
4. Install Appleworks 6.2.9 into Snow Leopard Server and it will now run concurrently with Mt. Lion:

my iphone is broken,and i came to store to change a new one today. When I come home, I found I lost my backup and may be mistake is made during before backup.The information in my previous iphone is really important for me? how can I get the backup back?
If you don't have a backup then the only possible solution is to go back to the store and see if they can get your old phone and create a backup of that. I know very often that Apple employees will wipe the returned iPhones clean before shipping them back to wherever they ship them.
When you say your old phone was "broken" does this mean it is dead and won't turn on?
Do you have a Time Machine backup of your computer, or a clone that might have this info on it?
Other than that I hate to say you may be out of luck. Time Machine and/or a cloning program performed regularily will inevitably save your a** in situations like this.
Good luck

How can I get the value of "Warehose" column in a form
How can I get the value of "Warehouse" column in the form below (I mean what table that contain this value):
Production Supervisor >> Batches >> (Button) Material Details >> (Button) Line Allocations
Well, for more clearly! My problem is I must have the Unit Cost of Items, so I've got it in the cm_cmpt_dtl (table), but if I want to, I must create a relation that require 2 filed, they're Item_ID and Whse_Code.
There's no problem with Item_ID, but Whse_Code seem to be the Mission Impossible (hix, I hate that film!!!!)
I wonder if It was right to post this topic here. But anyway I just post my question here, hope I could get some help.wow, many, many, many.... and many thanks!
Just add a tiny modify to check out the Batch_type
doc_id = (select batch_id from gme_batch_header where batch_no='&batch_number' and batch_type = 0)
Because the batch_no can be duplicated as we also create Batch and Filrm Planned Order.
Many thanks for your support!

You can use the dbms_utility.get_time tool (gives binary_integer type value).
1/ Initialize you time and date of beginning :
v_beginTime := dbms_utility.get_time ;
2/ Run you procedure...
3/ Get end-time with :
v_endTime := dbms_utility.get_time ;
4/ Thus, calculate elapsed time by difference :
v_elapsTime := v_endTime - v_beginTime ;
This will give you time elapsed in of 100th of seconds...
Then you can format you result to give correct print time.
Hope it will help you.
