How many processes after intial start on RedHat 7.2

Ok, I'm trying to do an evaluation of Sun ONE 7 (or whatever the official name is now) using RedHat 7.2 on a 500mhz PIII dell with 192MB of memory. Before I start the appserver there are 73 processes on the box, after I start the appserver, there are 253 processes. Seems a bit extreme. I've tried the install on a Solaris 8 box, and the number of processes is significantly lower (approx 10 additional processes after start-appserv).
I've tried the install with and without the sample applications. What gives here (other than my CPU load ... )
thanks,

While this may sound extreme, I believe that what you see is due primarily to a difference in Java native thread handling between Linux and Solaris - on Linux, each Java native thread will get its own process table entry while on Solaris this is not the case. This got "fixed" in RedHat 9....

How many processes for Start processes

Hi Community,
                        I am new to process chains, I am creating process chains for master data loading. Here I am adding " Execute Info Package " for every Object.After adding 10 different objects system not allowing me to add new process type (" Execute Info Package ") to this list. Please some one tell me max how many process type we can include for a start process.

Hi Bhanu,
                   I added new process type (Execute Infopackage) for infoobject 0VTYPE to start process variant. When I am trying to Check the process I am getting message called "PROCESS WITH WARNING MESSAGES". And on the context menu of the node to go for Displaying Messages , Too many parallel processes for chosen server .
                     Please let me know if you need any further information.

How see how many process in paralell are running?

Hi friends!
I need add a new process chain in the main meta- process chain ( a big one)
How can I know how many process are running in paralell,
and how many process still free or available to use,
between a time range? (ex: 12:00hs to 12:10hs)
Thanks in advance!

Hi
There are various ways by which you can determine whether you have enough background work process to run something in parallel.
1. When your process chain is running use transaction code SM66 to see how many background process are being used.
For background work process you get TYPE as BTC. Now monitor this screen for some time and you would know what is the maximum number of background process being used during your PC run. Your Basis team member will be able to tell how what is the total number of background work process in your system. Now you would be able to understand how many of these process remains free.
2. You can run SM51 -
> this will list you number of application servers you have. Double click on each of the server , it will take to to SM50 screen. Top side there will be clock sign. Click on that. This will give you the CPU time of each work process.
i.e what is the time a wp was using CPU since last system restart. If you see for most of the background work process this time is in the range of 0 - 2 seconds , then they are mostly free .
3. You would also get some of the valueable information from RSBATCH -

How many process on a paticular listiner...

Hello all,
Is there a way to check how many connections/process are using a paticular listener ?? I have 3 diff listiner (obviously 3 diff ports )and wanted to know how many connections a paticular listner is hanlding at this current moment ??
i know i can check the lsnrctl services, but it only gives me how many connection it establised and how many it refused. But wanted to know how many current users are connected to one paticular listiner ?
i am on hp-ux and running 10.2.0.1

if the listiener has nothing to do after the handoff,
how would we determine how many user are connected using a paticular port ??You suffer from MANY misconceptions regarding how SQL*Net actually works.
For DEDICATED SERVICE connections each session uses its own "random" high port.
For V10+ no listener.ora file is required to start or run Oracle listener.
do as below so we can know complete Oracle version & OS name.

How many processes?

Hello,
I have a question about how many concurrent processes within a single process chain could I start with? That is, from the start process, how many could I trigger at the same time?
Eg. :
Start Process
|
P1 P2 P3 P4 Pn
Does it mean each process (P) take up 1 batch process?
Pls give a hint thanks.
Regards,
Alfonso S.

Alfonso
After start process you could use any number of process you want. In your example You could runn P1, P2, P3 and P4 in paralle or one after other depends on your requirement.
Yes each process will take one batch process
Hope I answered your question

How many bars after 2.1 update?

Here's my story:
I bought an iPhone 3G shortly after it came out. I was very happy with it but it got horrible reception on 3G mode. I went and checked the att coverage map and I was supposed to have perfect 3G coverage, however I only had 1 bar. So after a few days of having a 3G phone that doesn't use 3G, I decided to return it and re activate my original iPhone. My question to all of you iPhone 3G owners is, has the 2.1 software update fixed the reception issue or is it still not working? If it is TRULY fixed, I will definitely buy another one.
Thanks

Since updating my phone to the new 2.1 Firmware I have been seeing my phone at full bars which I normally don't see on a regulars bases like I do now but if I am having full bars why am I having connectivity issues like when I am talking on the phone it is constantly breaking up almost to the point it sounds like a blown speaker and when I send a SMS it pauses at the end of the loading box for about a minutes before the messages is completely sent. These 2 issues I have never experienced until right after the install of the new 2.1 Firmware

How many process in order to implement a multi-operations WSDL?

Hello everyone,
I have designed a WSDL describing two operations, that I want to implement with BPEL.
I was wondering whether I needed to implement two BPEL files independently, one for each operation, or I was compelled to put the orchestration of both operations in a single BPEL file, with the help of a pick activity to separate the flows.
I tried both ways and only succeeded with the latter, but I am not convinced with the approach. The first option falls short when building the CASA. I get a "WARNING: 1 port with 2 providers", and effectively only one operation is exposed.
According to you, what is the way to go?
Thanks

Hi, Ricardo,
Why do you need to do this? What is the business requirement that demands this? It seems like a waste of time and effort, and you'll have to re-do it every time a row is INSERTed or DELETEd, or when any of the columns involved is UPDATEd.
Given that you really want to do it, here's one way:
MERGE INTO     table_x          dst
USING (
           WITH    got_nums     AS
               SELECT key1, key2, filename
            ,       ROW_NUMBER () OVER ( ORDER BY key1 )
                                                   AS key_1_num
            ,       ROW_NUMBER () OVER ( ORDER BY SUBSTR (filename, -8)
                                               ,         key2
                              )     AS filename_num
            FROM    table_x
        SELECT k.key1
        ,        f.key2
        ,        f.filename
        FROM        got_nums     f
        JOIN        got_nums     k ON f.filename_num = k.key_1_num
       )               src
ON     (src.filename     = dst.filename)          -- or any unique column(s), not including key1
WHEN MATCHED
THEN UPDATE SET dst.key1 = src.key1
;If you'd care to post CREATE TABLE and INSERT statements for the sample data, then I could test it.
As posted above, this assumes that filename is unique. If not, you'll have to change the join condition between src and dst to guarantee a unique match.
This does NOT assume that filename is always 19 characters; only that it is at least 8 characters, and that the last 8 characters determine the order.

How many cpus on server are allocated to client

hello,
its not an issue rather doubt which is hunting me from last 2-3 days.
My 10gR2 Oracle database running on
Widows server 2008 R2 Enterprise
Processor ----> intel Xeon cpu [email protected] GHz (4 processor)
RAM------>8GB
its a dedicated server.
Actually i was going through the AWR report whn one of the client came to me with slow database performance during some time interval.
when i had a look at the Top 5 Timed Events in Report it showed me the
Sql*net message from client      834.35si told them to run their query so that i can have trace of that.
then time event showed me something nearer to above and our database was taking only 15 sec to carry out the task.
i told them that
"you application/client is taking 834 sec to tell our database to do something.But once the database got your application's request to carry out something, the database is taking only 15 sec to provide you with the result"
so they asked me to justify that the problem is with application side/machine side.
After digging in a lot on the internet ground, chatting with my colleges on cell phone and running through many threads specially Asktom.oracle.com, i got really confused.
They came up with varied opinions which kept me thinking again & again over the same thing.
In one of his(Thomas kyte) thread the discussion was as follows.
The output of tkprof when the developers run the same program on their PC shows a big difference in
SQL*Net message from client.
The SQL*Net message from client from my tkprof is almost 4-5 times theirs.
Could you please advise what might be the cause of that?
Thanks

that could mean.....
your machine is slow (their desktop cpus blow your server cpus away) as much as anything.
since their code is not instrumented, try SQL*Net trace (with TIMESTAMPS) can be helpful to check out the time in the network between the client and server. See Note 16658.1 - see if you experience radically different response times on the various machines.

My Database server is T5120 with 4 core 1.2 GHz Ultra SPARC T2 processor (from O/S it is seen as 32
CPU * 1.2 GHz).
Their PC has 2 CPU * 4 Ghz.
Based on the above, How come their PC is more powerful than my server?
The ASH Report for the execution period of the program shows ¿CPU + Wait for CPU¿ is the top event,
however, tkprof shows ¿SQL*Net from client¿ is the top event waited on.
Top User Events
Event        Event Class    % Activity    Avg Active Sessions

Can you please explain why there is a difference between tkprof and ASH report?

I only care about a single cpu, your client program is not using more than one.
I often downloaded stuff from my big bad sparc to my desktop because my desktop was many times faster than the sparc.
look further down in the ash report - sqlnet message from client is an idle wait, we tend to ignore it as it is the time we spent WAITING FOR THE CLIENT.
Their pc looks a lot faster than your server since you are only using a single cpu - your client is not multi-process. It only uses a single cpu.

Sorry, I forgot to say that during the execution time the cpu on the server was 98-99% idle based
on (using top and sar).
Thanks
Followup   August 25, 2009 - 8pm Central time zone:
I agree, because you could not use 31 out of 32 cpus, I would expect it to be almost idle.
97% idle would mean a single cpu was 100% used. So, it sounds like you were using almost 100% of that single cpu you had access to.
and it isn't as fast as their pc.

Followup   August 26, 2009 - 7pm Central time zone:
how about this.
have the developers write something that mimics what they do without the database in it. Same sorts of loops and processing they do in the code in the client.
run it on their machine
run it on yours
You'll find your big bad server has cpu's that are extremely slow compared to the desktop machine.
Hence - the time spent waiting for sqlnet message from client is - time spent in YOUR client on YOUR server processing the data returned from the database.
saying "the cpu 0.17 on one and 0.48 on the other" is meaningless, they are completely different cpus with completely different performance characteristics.
And that you have 32 of them - no use to you, you use one..
It looks like your server is about 2-3 times slower then their test machine.

Hi,
I just read your post as I experienced the exact same problem. I found something that fixed this
problem for me, my sqlnet.ora contained that line after an oracle upgrade:
TRACE_LEVEL_CLIENT=16
I don't know how it came there. But it was the cause of my problem (too long idle time). I simply
removed it and no more wait events.
I hope it can be of any help for anyone.

Reviewer: A reader in this thread Tom insisted that the client has access to only 1 CPU on the server even though the questioner told him that his machine is having around 32 CPU'S.
so this thread was the source of my confusion.
i kept asking myself "if the client application has access to one cpu out of 32 cpu's on the server on which the database server is running,then What is the use of multiprocessor? my oracle/client application has access to only one cpu on the server(like Tom said), what other 31 cpu's on the server machine are upto?if one cpu is getting exhausted by the client Application request, then what the other processor are doing ? are they not meant for load balancing?"
when i had a chat on cell phone with my colleagues regarding the oracle access to the cpu's on the server, then they told me that if there are more number of cpu's then the the response time would be fast cause workload is divided among the multiple processor to carry out the task in parallel.
Again i got confused with the deferring opinion..
so just want to have clarification on
* how many processes do i have access to on server machine where my oracle is installed?*
how many processes do the client applicaiton S/W/client machine have access to out of 32 processors?
is workload devided among the cpus on the server ,in case of huge request from the client application?
thanks & i hope my doubt would be cleared

Look at it in basic terms (forgetting for the moment about Oracle and SQL*Net and specific s/w itself).
A process is loaded into memory. This process contains machine code instructions. How many CPUs can execute these instructions?
Only 1.
Simplistically. The process has a single execution pointer and set of CPU registers. A single CPU executes the instruction (as indicated by the execution pointer). The registers are used and updated.
The same CPU may not be used each time around. So a single process can during its lifetime, be executed by a number of CPUs. But a single CPU at a time.
A process can thread. This basically means that a second copy of the execution pointer and registers set are created. Each such copy will be executed by by a single CPU at a time.
An Oracle client is serviced by an Oracle server process (either dedicated or shared). On Linux/Unix systems, this will be a unique physical process. On Windows, it will be a unique thread.
This process is executed by a single CPU. Thus that client is serviced by a single CPU.
This changes when Oracle can use parallel processing and there are PX slave processes available. In that case, the client is serviced by a single process - but that process has in turn enlisted the assistance of helper processes. Thus the client is now serviced by multiple processes (or threads on Windows) and thus by multiple CPUs.
However, it is not that simple either. It is "cheaper" for the kernel to run threads on the same CPU than on different CPUs. The reason is the same memory is used by both and access to that memory by different CPUs is more complex (and thus more expensive and slower) than from the same CPU.
So depending on a number of factors, that client may still be serviced by a single CPU despite the fact that PX slaves are used. And from a client process perspective, this does not really matter. The crux of the issue in this regard is the CPU utilisation/footprint of that client process on the server.
If the clock time for a client process says "+running for 60s+" and the server says "+CPU time is 10s+", you cannot say that the process was not serviced by multiple CPUs. You do not know whether than 10s CPU time was for 5 processes each spending 2s to service that client.
However, when the server says "+CPU time is 70s+" - a longer period that the wall clock time of the client, then it is reasonable to assume that multiple server processes (and thus CPUs) are servicing that client process.
As for exactly how many CPUs are in fact used by the server? That has no real bearing on this. It does not change client-server behaviour.
Even Oracle does not know and does not care which CPU is servicing it. The correct piece of s/w to deal with that, is the kernel. Yes, you can bind a thread or process to a specific server CPU, but the reasons for this is quite technical and is always an exception. Let the kernel deal with which CPU to use. It is of no concern to the server s/w (like Oracle), and even less to the client process being serviced by that server s/w.

They don't normally appear in the download screen ... until I attempt to download another movie. Then they just start appearing. If you click edit - a normal movie download has a circle that appears on the left hand side that allows you to select and delete ... these movies don't have that option so you need to find the movie in you list (under movies) and select the download cloud symbol again to stop it downloading ...you may need to do this a number of times before it stops for a while ... or until you try to download a movie then it starts all over again.
i have logged out of my itunes account. restarted the iPad, removed all movies, restarted the iPad, logged back into my iTunes account and restarted my iPad .... but as soon as I tried to download a single movies ... the other movies started appearing in the downloads again.

I want my program to run other programs, but I also want the User to be able to stop the running program from within my program. How do you keep track of what program Process.Start has run?
The Start(String...) or Start(StartInfo) methods of the Process class are functions that return a Process object that you can then use to manage the process that you started, for instance to stop it with .Kill.

How many times can i call the start()

Hi All:
I would like to know how many time you can actually call the start(),
cuz my app is doing some really strange things,
here is a fragament of my code:
private void spawnThreads()
ListIterator it = _vWorker.listIterator();
while ( it.hasNext() ) {
ClientWorker client_worker = (ClientWorker) it.next();
client_worker.start();
ClientWorker is another Thread, and in the run() of the ClientWorker, I have
public void run() {
Runtime rt = Runtime.getRuntime();
     try {
     // Start the timer
     Process child = rt.exec(_fileName);
     // gobble any error or output streams
StreamGobbler errorGobbler = new
StreamGobbler(child.getErrorStream(), "ERROR");
StreamGobbler outputGobbler = new
StreamGobbler(child.getInputStream(), "OUTPUT");
errorGobbler.start();
outputGobbler.start();
child.waitFor();
                                        } catch (IOException e) {
               System.err.println("IOException starting process!");
          } catch (InterruptedException e) {
               System.err.println("Interrupted waiting for process!");
I have a couple of cmd files to execute, so This spawnThreads() will be called a couple of times,and the funny thing is , it will execute the first cmd files, and that is it, it won't execute the 2nd or the 3rd cmd files, it will start the thread, but then the run()won't actually gets invoked,,,so I am just wondering if anyone of you has encountered this problem, perhaps you could lend me some insight on this?
thanks,

Yes, you can run the start() of a Thread more than once,
here is my Test App,
public static void main(String[] args) throws Exception {
Vector vec = new Vector();
for (int i=0;i<4;i++){
ClientThread ct = new ClientThread();
vec.add(ct);
ListIterator it = vec.listIterator();
while(it.hasNext()){
ClientThread ct = (ClientThread)it.next();
ct.start();
and as you have already guessed it the run() of ClientThread simply does system.out.println()
and here is the output
run started
run started
run started
run started
so..yeah..I don't really have any idea what is happening to my app and why it is not executing any cmd files after executing the very first cmd file

5 min after fired of this stmt. i want get information that how many row it has updated so far and how much is left. What's the reason for such requirement? I can't think of anything which would require this except that the Update is updating some millions of rows and you want to know when it would eb finished. But even for that, there is no way to know AFAIK that how many rows currently have been effected by the statement.
does the total_work.gv$session_longops , column can help ????No, that would only show the total work done in % . It won't reveal and update continously the row count of rows getting updated.
joining v$session, v$transation , v$rollstat can only tell me how much undo blocks are used so far, not rows.Nope, as I said already, there is no way at least in my knowledge to check this and IMO, there is no need to know this as well.

I am currently working as a Accounts Payable Supervisor and I would like to run a report to show me how many invoices are being processed by users in my team.
Currently I am using Transaction F.98 (Posted Docs by user report), but this report includes posting from intercompany so all users will have duplicate invoices showing on this report.
Is there any other report I could run to get the result I am after?
Many thanks
Alex

Hello Alex,
You can also use the GL line item report (FBL3N) with the offsetting accounts (for example GR/IR A/c) which would be posted while posting the invoice. You can display the results with User Name and also can create a layout of your own which can be used time and again.
Kind Regards // Shaubhik

How many different way can we call a BPEL process

Hi Guys,
How many ways can we call a BPEL process
I know 3 ways
1 ) Thru PLSQL 2) using Java API 3) From another BPEL Process.
are there any other ways .... if so what are they ..... .
Thanks
Tom...

Hi Tom,
your normal BPEL process (a regular process you create with the "new BPEL process" wizard), can be configured in Oracle application server to be accessible
- via SOAP over HTTP or
- via JMS
since it is has a WSDL based service interface.
JDeveloper as well allows additionally more options for starting a BPEL process such as a file based interface, an e-mail as a starter etc.
Still, I like to see the ESB as a virtualizer of the endpoint protocol, so I suggest you model the BPEL process regularly, exposing its functionality through WSDL and use ESB services that wrap your BPEL process to deal with the actual endpoints.
Cheers,
Hajo
