How many parallel threads

Can any of you point to a query to show how many parallel threads are being used by a specific OSUSER. A load runner test is being done and the application server issues a set of dmls to an Oracle database. The v$session table shows all the sessions associated with the (application server) osuser have status 'INACTIVE'. Does it mean that none of the dmls are being executing? Which other data dictionary tables/views do I need to join to v$session to get a correct picture of the parallel threads being used.
Thanks in advance.

Hi James
Here is my problem. I need to do this for load balancing. I have two instances of SOA Suite running on single machine, i.e. two different BPEL servers. Now i need 2 BPEL instances on each server, i.e. two SOA Suite and four BPEL instances (Two BPEL servers on each SOA Suite)
I tried to create a new OC4J instance on my app server and named it as OC4J_new. By default OC4J instance would have these application installed:
ascontrol
ccore
coreman
datatags
default
esb-dt
esb-rt
gateway
hw_services
javasso
orabpel
orainfra
policymanager
ruleauthor
rulehelp
But when i create new OC4J instance, i can see only these applications:
ascontrol
datatags
default
javasso
How do i get rest of the applications in my new OC4J Instance??
I tried deploying .EAR files but it failed all the time. What are possible fixes?

How many parallel servers should I use?

Hello All,
I am in 10g and would like to create table as select. I am using NOLOGGING and PARALLEL. I notice, as I go on increasing the number of parallel servers, I cost of my statement reduces.
create table tmp_xyz NOLOGGING PARALLEL 12 as
SELECT ...
from ...
value of PARALLEL_min_SERVERS and PARALLEL_MAX_SERVERS parallel servers is 0 and 240 respectively.
I am doing this for a large data table migration; no user be working at the time.
I wonder how many parallel processes I should use?

I wonder how many parallel processes I should use? Each parallel process is used for doing I/O - the I/O load is what is parallelised. Each PX slave gets an I/O load (usually a rowid range that describes a range of physical row-on-disk addresses) to process.
So your question boils down to what the I/O capacity is of the I/O subsystem on that server. And this is pretty unique to a server and depends on just how the I/O layer looks like.

How Many Parallel Slaves used in past for a module

11.1.0.7 on RHEL 5.4
Is there any way to check with how many parallel slaves a module ran in past (3 days prior) ? It was a MERGE statement.
I am not sure ASH can be of any help or not ?

Means, you want to get the history of parallel slaves used in last 3 days right ?
If think you may get little information from this link.
It will open page No. 471. Just read from page 471 to 473. It will provide some light on your question.

How many active threads in JVM?

Is there a way to find out all the running/active/blocked/unknown threads in a JVM?
Doesn't matter if it is through code or some external command.

suri'jdb' tool lets you know how many threads exist in an application. try these command
compile your program with '-g' option.
jdb <classname>
stop at <classname>:<line no of main(){}>
run
threads
You can notice four threads. But I guess in linux, it might show lots of verbose with thread ID, If possible pls post the result for us to see.

SMTP Conversion Threads - how many?

I am wondering how many conversion threads one should set for inbound/outbound SMTP traffic on a GWIA.
The GWIA in question handles the following in a 24 hour period:
Inbound 12000 - 15000 messages
Outbound 3000 - 5000 messages
My conversion threads are currently set to 7/7.
Is this too low? What would the GURU's suggest?

Thank you for your reply - much appreciated.
There is no backlog of mail. The GWIA appears to be working fine with those settings, but I always like to fine tune my system for best possible performance.
I was just wondering if there were any recommended settings for GWIA or if there's some kinda calculation ie this amount of inbound mail per minute requires this amount of conversion threads.

How many threads can be running at the same time

Hi!!
Dows anyone knows how many Threads can be running at the same time in the JVM.
I'm making a multi thread client-server app and I would like to know how much simultneous connections the JVM support. I'm using one Thread per connection.

Hi, thanks to all for your answers.
I think that I made the wrong question, as you said: "that means the number of threads currently created".
I'm worry about this because my application is already online (It's a mail server -SMTP and POP3 server using ORACLE for the users database- ) and some other user post in the "multi-tread forum" that almost any JVM can only have 700 threads created at the same time, and I've never heard or read anything about this.
what you mean with the stack space (memory??)
I'm using the JavaWebServer 2.0 and a servlet to start the main Thread.
Again Thanks to all for the answers but I think that the schapel answer is the one that solve my doubt...

How to use notification with parallel thread

Hi,
I am learning to use Notification to communicate between thread. I still don't know how to use it. In my current project I have a case to use this so I think I should implement this technique. My example is I have a main sequence in that I make a new thread. What I want is the new thread will do a task A when receive a notfication or to exit the thread when the main sequence stop.
I am not sure if using notification is a best practice here? Or should I use a reference data?
What about if I want my thread to do task B if it receive another notification. Is notification still be helpful?
Regards,
Thang Nguyen
Solved!
Go to Solution.

Hello,
You can use Notification to handle parallel threads. I often create two sequences : one containing the process A of your example (StartProcessA). and a second one to stop this process (StopProcessA). In StartProcessA, I create a Notification, with a defined name (as string constante, "StopProcessANotifier" for instance) in the setup group. Then I have the process, in a loop. At the end of this loop, I check the Notification (Wait) with a timeout enabled, and no error if a timeout occurs. this way, the Notification Wait can be used as loop timing, and if the notification is Set in MainSequence, this exit the loop (pick a look at Notification property Step.Result.TimeoutOccured).
To sum up, use a first sequence call in MainSequence, calling StartProcessA, with NewThread option, and do not forget to call StopProcessA at the end of you MainSequence. The Cleanup group is a very good location, because it will be executed even in case of error.
This is a very simple use of Notification. Note, I believe that make it simple is often the most important but also the most complicated thing to do
Hope this helps....

How many threads are running?

here's the code... i am trying to understand, at each point, how many threads are running:
I understand that one thread belongs to the caller of the start()
& at the same time there is another thread belonging to the instances of each thread (thread1, thread2, thread 3 etc.)
1public class ThreadTester {
2   public static void main( String args[] )
3   {
4      PrintThread thread1, thread2, thread3, thread4;
5
6      thread1 = new PrintThread( "thread1" );
7      thread2 = new PrintThread( "thread2" );
8      thread3 = new PrintThread( "thread3" );
9      thread4 = new PrintThread( "thread4" );
10
11      System.err.println( "\nStarting threads" );
12
13      thread1.start();
14      thread2.start();
15      thread3.start();
16      thread4.start();
17
18      System.err.println( "Threads started\n" );
19   }
}can you tell me if i am counting the number of threads in existance correctly...
LINE#.....CALLER...START...TOTAL THREADS
13..............1.........1.......2
14..............1+1......1+1.....4
15..............2+1......2+1.....6
16..............3+1......3+1.....8
so by the time line 16 executes i have a total of 8 threads,
4 threads belonging to each caller plus
4 threads created by start()
or is it
LINE#.....CALLER...START...TOTAL THREADS
13..............1........1........2
14..............1........1+1.....3
15..............1........2+1.....4
16..............1........3+1.....5
after line 16 executes does the caller thread die, thus leaving only a total of 4 threads?
there is only one thread belonging to the caller at line 13(plus the thread it creates).
at the start of line 14, the previous callers thread is dead & now a new thread is created that belongs to the caller on line 14... etc.

well, i realize at the end there would be 4 threads but im trying to get my head around this explanation in the book:
"A program launches a threads executioin by calling the threads start method, which in turn call the run method. After start launches the thread, start returns to tis caller immediately. The caller then executes concurrently with the lauched thread." there fore if i have 2 concurrent processes, are there 2 threads running????
now having said the above, my question was:
for each line,
how many threads are in existance at
line13
line14
line15
line16
thanks.

How many Threads on a given system ?

Is there a way to know for an AIR application how many threads a given system system supports?
Pixel Bender is capable of real multi threading. It would not make sense to run 4 instances on a system with only 2 threads, but would be a shame not to utilize all threads of an 8 core hyper threading system.
Thanks,
David

How Many Threads inside JVm while running

Hi,
how many threads will be there in jvm of 1.4 or higher sdk? threads i mean it includes all jvm threads also.

How do you identify these threads?
I can see 8 threads in my 1.5 java process (just running a main) using windows XP task manager, but when I check how many threads there are from within the code, it only looks like 4:
java.lang.ThreadGroup[name=system,maxpri=10]
Thread[Reference Handler,10,system]
Thread[Finalizer,8,system]
Thread[Signal Dispatcher,9,system]
java.lang.ThreadGroup[name=main,maxpri=10]
Thread[main,5,main]
For example, using
Thread.currentThread().getThreadGroup().getParent().list();

How many DATALOADER instances in parallel ?

Hello,
To decrease the duration of my initial dataload, I would like to use several DATALOADER instances in parallel.
How many instances can I launch in parallel ?
Thanks for your help.

The solution is to run flexlm servers on fixed ports.
For example, to run Adobe License Server on fixed port say 27000, modify adobe.lic file. First stop the Adobe License service, Open the adobe.lic file in notepad (any text editor) and change the first line to SERVER this_host ANY 27000. Save and close the file and start the Adobe License Service.
Similarly, you may specifiy the fixed port in other flexlm servers. Adobe Console by default assumes the license server is running on default ports i.e. 27000-27009, you may specify the license server port where the Console should talk to the Adobe License Server (via Admin Tab->License Server configuration web page).

How many HACR can run in parallel in SAP BW 3.5 and 7.X?

Hi Experts,
I have a question that How many HACR/attribute change run can run in parallel in SAP BW 3.5 and 7.X?
I know in SAP BW 3.5 only one ACR job can run and if we start any will be failed due to lock issues. On other hand, I also noticed in SAP BW 7.3, there are more than one HACR job running in parallel without lock issue.
Does anybody know the reason behind this? how many ACR job we can run in parallel and precautions to be taken care everything.
Please share your thoughts and lets understanding the ACR in detail..
Thank you.
Bharath S

Hi Bharath,
I' am not sure but I' am sharing what I think
New version is always some betterment of old version. Time changes, advancements in technology, performance improves.
However, I want to ask "Can we run two HACs at a time which use same info object in 7.X ?"
