How to detect the number of logical processors?

Hi,
How to detect Hyper-Thread Technology, the number of processor cores on a single package, and the number of logical processor?
What java api can do this?
Thanks for help!

How to detect the number of marker (cuepoitName) with same name from a list.

... it is the second step of my previous question.
From a sound I take a list of cuepointName with different name, for exemple:
Mylistcuepoint = ["reg 01", "reg 2", "name 1, "name 2", "name 3"] etc.
Which command I must use to detect the cuePointTime only for the cuepointName: "name 1", "name 2" "name 3" ...
My second question, for a second script is: how can I count how many cuePointName with "name 1", "name 2", "name ...." I have in "Mylistcuepoint"?
I can load several sound member so "Mylistcuepoint" can change obviously for the number of marker of "reg ...." and for the number of marker of "name ...." but the first word ("reg" or "name") it will be always the same.

I already showed you how to do this in response to your last question.
My second question, for a second script is: how can I count how many cuePointName with "name 1", "name 2", "name ...." I have in "Mylistcuepoint"?
It is a list like any other. Iterate through the items looking to see if they match your criterion/criteria and increment your found count (or add indices to a list) as you go:
tSearch = "name 1"
tFoundCount = 0
Mylistcuepoint = ["reg 01", "reg 2", "name 1, "name 2", "name 3"]
if Mylistcuepoint.getPos(tSearch) then
repeat with nn = 1 to count(Mylistcuepoint)
if ( Mylistcuepoint[nn] = tSearch ) then tFoundCount = tFoundCount +1
end repeat
end if

How many processor of license for oracle i have. I think its 48. Can you confirm me in this regards
regards
Nick

You have 24 physical CPUs, each of which have 2 cores, thus giving you 48 cores, correct? If so, in order to license that server today, you would need either 48*0.25 = 12, 48*0.5=24, or 48*0.75=36 processor licenses depending on the type of CPUs you use.
However, when you licensed the software in the past, though, the licensing terms were fixed as of that point in time. It is entirely possible that
- Oracle was using different logic to calculate the number of required processor licenses for multi-core CPUs today than it was in the past and you only needed 1 processor license for every 6 cores
- Your company negotiated a different core multiplier than is or was in the standard licensing agreement
- Your company negotiated some other sort of exception that allowed them to buy just 8 processor licenses
So you would need to read through the specifics of your license agreement to determine what, specifically, your company agreed to in order to determine whether you have enough licenses. If you are short some licenses, you would also need to read the agreement to determine how you go about rectifying that (i.e. can you purchase additional processor licenses under the original terms or do you have to add licenses under the current license terms, etc). Of course, I'm sure your Oracle Sales rep would be more than happy to assist you in determining whether you need to purchase additional licenses.

Increasing maximum number of Logical Processors in a Processor Group greater than the default (64)

Can the maximum number of Logical Processors allowed in a Processor Group be increased by Bcdedit command or registry key to a number greater than the default (64) to allow non-group-aware applications to seamlessly scale via multithreading across more cores
MSDN documents methods to reduce the max number of LP's in a Processor Group to 1 or any power of 2 less than 64 in order to increase the number of Processor Groups. But there is no discussion of how to increase the maximum number of Logical Processors
allowed in a Processor Group to a number greater than the default (64), e.g. to 128 or 256.
Since a non-group-aware application/process can only run on 1 Processor Group, increasing this limit is needed to allow non-group-aware multithreaded applications to scale seamlessly for parallel computation across more than 64 cores simultaneously on systems
with more than 64 cores (for example, a quad-socket Intel Xeon system with 24 cores per socket, including true and hyper cores). If that limit can be set via registry key or command line, or if there is another way to force all the cores on
all 4 sockets (4 NUMA nodes in this case) to join in 1 Processor Group, then non-group-aware applications will not need to be rewritten using group-aware thread-affinity APIs.

Hi John,
Are you trying to specify a static NUMA-node-to-group assignment, rather than letting Windows dynamically assign NUMA nodes to groups at boot time? If yes, You can refer the
following related KB:
How to manually configure K-Group assignment on multiprocessor machines
http://support.microsoft.com/kb/2506384
Systems with fewer than 64 logical processors always have a single group, Group 0. On systems with 64 or fewer processors, existing applications will operate correctly without
modification. Applications that do not call any functions that use processor affinity masks or processor numbers will operate correctly on all systems, regardless of the number of processors. To operate correctly on systems with more than 64 logical processors,
the following kinds of applications might require modification:
•Applications that manage, maintain, or display per-processor information for the entire system must be modified to support more than 64 logical processors. An example of
such an application is Windows Task Manager, which displays the workload of each processor in the system.
•Applications for which performance is critical and that can scale efficiently beyond 64 logical processors must be modified to run on such systems. For example, database
applications might benefit from modifications.
•If an application uses a DLL that has per-processor data structures, and the DLL has not been modified to support more than 64 logical processors, all threads in the application
that call functions exported by the DLL must be assigned to the same group.
By design, a non-NUMA computer is considered to have one NUMA node. Because NUMA nodes cannot span groups, the system creates a node for each group after you restart the computer.

How to detect the sign of a number?

I have output which gives either negative number or positive number. My problems is how to detect the sign of the number and output boolean value? For example if input number is negative like -23.11 I want to output false and if the number is positive like 17.99 I want to output true.

Have you installed the Oracle HTTP(OHS) server yet ? If you have then the HTTP config file should specify what port the HTTP server listens at. This port is the port number you use to access APEX

How to detect the path of Temp directory

I am writing a class library which allows users to manipulate a database in the web server java applications/applets. In my logic the Application/Applet communicate with a CGI script/Servlet in the server and that do all the database handling. My objective is to make the Client independant from the Database Drivers, and to some restrictions and possible security threats that can arrice when accessing the database directly.
99% of the work is done and now I am doing the fine tuning.
My Problem:
When the user downloading a blob object from the server database. each time the program read the blob it will get a new copy from the server. This is not good if the blob is large (few 100 megs) . So I am going to implement a cache system. but the problem is If I am caching in the memory it will not support large objects (Memory is a limited factor). So the preferance is use the Temperary files but I do not know how to detect the path to temperary folder.
And my 2nd questions is are the applets allowed to write and read in temperary folder.

The Java default temporary file path can be determined with
System.getProperty("java.io.tmpdir")This is typically the same value as the os environment variable

How to know the number of rows of a ResultSet

Hello.
I'm trying to detect the number of rows of a query result before making all the results.next().
Until know, my way was:
ResultSet results = sql.executeQuery();
while( results.next() )
int i = 0;
... do stuff ...
i++;
out.println("The number of rows is: " + i);
But I would like to know the value of 'i' just after 'executeQuery'.
Does anybody have any experienc?
Regards.

How about like this???

How to calcuate the number of days

Hi Friends,
can some one help me out .. how to dispaly the number of days depending upon the from and to date selected by the user.
eg :-
there is one self service form.. in which three fields are there, they are 1) From date
2) To date
3) No of days
now my requirement is, user selects from date and to date and i need to calculate the number of days he is selected and display in No of days field. can some one help me out logic for this.
how to retrive from date and to date dynamically to my function.
apart from writing function .. can we use $FLEX$ becoz two dates are valuesets.
seeking for a solution,
thanks in advance

This doesn't sound like something that will be easy to do.
A few questions:
1) What flexfield are you referring to?
2) What Self Service page?
3) Can the 'No of days' ALWAYS be calculated? Or do you just want to default it so the user can modify it?

How to delete the number saved in CALL FORWARDING list?

how to delete the number saved in CALL FORWARDING list? seems like the number cannot be deleted in CALL FORWARDING list, i tried several times...
he thing is, here are three numbers in the call forwarding list, one of them were set up by mistake, and none of them can be deleted.......it brothers me all the time. i already turn it off, but the number list is still there...

Hello dennis130915 and welcome to the BlackBerry Support Community Forums.
The image you have uploaded is unable to be displayed.
Call Forwarding is a carrier controlled feature. Most likely, the number you see could be for the Voice Mail server.
It's advised you call your mobile service provider to further assist with this feature.

How to find the number of data items in a file written with ArryToFile function?

I have written an array of number in 2 column groups to a file using the LabWindows/CVI function ArrayToFile...Now if I want to read the file with FileToArray Function then how do I know the number of items in the file. during the write time I know how many array items to write. but suppose I want the file to read at some later time then How to find the number of items in the file,So that I can read the exact number and present it. Thanks to all
If you are young work to Learn, not to earn.
Solved!
Go to Solution.

What about:
OpenFile ( your file );
cnt = 0;
while ((br = ReadLine ( ... )) != -2) {
if (br == -1) {
// I/O error: handle it!
break;
cnt++;
CloseFile ( ... );
There are some ways to improve performance of this code, but if you are not reading thousands of lines it's quite fast.
After this part you can dimension the array to pass to FileToArray... unless you want to read it yourself since you already have it open!
Proud to use LW/CVI from 3.1 on.

How to find the number of entries in a master data table

Hi Experts,
I am trying to find the entries in 0CUSTOMER master data.
BW>LISTCUBE>Data target: 0CUSTOMER and selected the fields that I need.
I would like to know how to find the "number of entrees". I tried to run the SUM for a count field, but it is taking forever as there are huge number of records .

Hi Dev,
Go to the change/display mode of the info object (0CUSTOMER) in your case. Go to the Master data/Text tab. Here you will find the master data tables according to your settings (P orQ or X or Y). Double click on the table name and it will take you to the SE11 display. From there, you can check the number of records as you do in any transparent table.
Hope this helps.
Thanks and Regards

How to find the number of links in a website

hi every body
can any one clear my doubt
my doubt is that
in a website how to find the number of links the hole website contains
is there any navigation tool to find that
plz help me yar
i am waiting for the reply

If you're talking about commercial sites (sites you don't have the source code for) I'm not sure.
If you want to count the links in site that you have the source code for, it should be relatively easy to write a Java application to do it. All you really need to do is have a list of the files you want to count links in, read each file line by line and check for the existance of the <a> tag in each line. Anywhere their is an <a> tag there is a link.
Hope this helps.

How To Ask Questions The Smart Way
Eric Steven Raymond
Rick Moen
Write in clear, grammatical, correctly-spelled language
We've found by experience that people who are careless and sloppy writers are usually also careless and sloppy at thinking and coding (often enough to bet on, anyway). Answering questions for careless and sloppy thinkers is not rewarding; we'd rather spend our time elsewhere.
So expressing your question clearly and well is important. If you can't be bothered to do that, we can't be bothered to pay attention. Spend the extra effort to polish your language. It doesn't have to be stiff or formal ? in fact, hacker culture values informal, slangy and humorous language used with precision. But it has to be precise; there has to be some indication that you're thinking and paying attention.
Spell, punctuate, and capitalize correctly. Don't confuse "its" with "it's", "loose" with "lose", or "discrete" with "discreet". Don't TYPE IN ALL CAPS; this is read as shouting and considered rude. (All-smalls is only slightly less annoying, as it's difficult to read. Alan Cox can get away with it, but you can't.)
More generally, if you write like a semi-literate b o o b you will very likely be ignored. So don't use instant-messaging shortcuts. Spelling "you" as "u" makes you look like a semi-literate b o o b to save two entire keystrokes.
