Oracle Multi-threaded libraries and Forte R3

Hello all,
I heard through the grapevine that it would be possible
to use Oracle 7.3 multi-threaded support with Forte 3.0G.
(thus making Load-Balancing obsolete in this case)
Has anyone given a try at this assumption ?
If yes, on what platform and what versions ?
Thanks,
Vincent Figari

Hi,
It is available In R3.0.F.2 also. I tested it this release and it works
very well. But, you need to make a design pattern on it : A Oracle
Session can not be shared between several transactions throught threads.
So You need to manage a pool of DBSessions.
Hope this Helps,

XA & Oracle - Multi-threaded

Hi All,
The Oracle XA documentation says that multi threaded
applications are
possible. But when i tried to open a connection to the DB using
XA_OPEN in
thread session with the same string it is giving an error in the
second
thread saying "XA_ERRPROTO: DB Name not unique", however sucess
in the first
thread. So multi-thread means multiple connections to diff DB.
So i opened one connection in the main thread, and i did a
XA_START with
diff. XID in both the threads. Again here in the second thered
the error is
"XA_ERRPROTO: Thread already associated".
So if these are standard ones how to write a mult threaded
application using
XA which uses only one DB.

Multi-Thread application and common data

I try to make a multi-Thread application. All the Threads will update some common data.
How could I access the variable �VALUE� with the Thread in the following code:
public class Demo {
private static long VALUE;
public Demo(long SvId) {
VALUE = 0;
public static class makeThread extends Thread {
public void run() {
VALUE++;
public static long getVALUE() {
return VALUE;
The goal is to get the �VALUE� updated by the Thread with �getVALUE()�
Thanks for your reply
Benoit

That code is so wrong in so many ways......
I know you're just experimenting here, learning what can and can't be done with Threads, but bad habits start early, and get harder to kick as time goes on. I am going to give a little explanation here about what's wrong, and what's right.. If you're going to do anything serious though, please, read some books, and don't pick up bad habits.
Alright, The "answer" code. You don't use Thread.sleep() to wait for Threads to finish. That's just silly, use the join() method. It blocks until the threads execution is done. So if you have a whole bunch of threads in an array, and you want to start them up, and then do something once they finish. Do this.
for(int k=0; k<threads.length; k++) {
threads[k].start();
for(int k=0; k<threads.length; k++) {
threads[k].join();
System.out.println("All Threads Done");Now that's the simple problem. No tears there.
On to the java memory model. Here where the eye water starts flowing. The program you have written is not guarenteed to do what you expect it to do, that is, increment VALUE some amount of time and then print it out. The program is not "Thread Safe".
Problem 1) - Atomic Operations and Synchronization
Incrementing a 'long' is not an atomic operation via the JVM spec, icrementing an int is, so if you change the type of VALUE to an int you don't have to worry about corruption here. If a long is required, or any method with more then one operation that must complete without another thread entering. Then you must learn how to use the synchronized keyword.
Problem 2) - Visiblity
To get at this problem you have to understand low level computing terms. The variable VALUE will NOT be written out to main memory every time you increment it. It will be stored in the CPUs cache. If you have more then one CPU, and different CPUs get those threads you are starting up, one CPU won't know what the other is doing. You get memory overwrites, and nothing you expect. If you solve problem 1 by using a synchronized block, you also solve problem 2, because updating a variable under a lock will cause full visiblity of the change. However, there is another keyword in java.. "volatile".. A field modified with this keyword will always have it's changes visible.
This is a very short explaination, barely scratching the surface. I won't even go into performance issues here. If you want to know more. Here's the resources.

Java multi-thread Applet and Multi-processor

Hello,
I have a JAVA applet which work fine on a mono-processeur machine and not fine at all on multi-processors.
It use multi thread (for reading on socket) and some times, request are lost.
Is that a matter of programming or a JVM bug ?
This happens on Linux and Windows NT bi-processors.
We hare using JAVA 1.3.0_02
Thanks for your help
[email protected]

I have already have a look to javax.swing.SwingUtilities.invokeLater() but (I think) it don't work for my need.
A graphic applet which create 2 threads : one for reading and one for writing on a socket.
Request sent to the server are memorized in a vector, and once answer is received, the request is remove from vector and treated. Access to the list is protected by synchronize.
Everything works fine one several plateforme (linux, windows 98/2000/NT, Solaris). The only problem is on multi-processor : request are lost !

Does Firefox 13 run in a multi-threaded mode and can it utilize quad-core processors?

When purchasing a new PC, one chooses between dual-core vs. quad-core processors and some people claim that Firefox run in a mulch-threaded mode and treats each tab as a separate process and that it can fully utilize the advantage of a quad-core processor. Is that true?

Firefox doesn't treat each tab as a separate process. While this may be a feature sometime in the future, I don't know of any plans to introduce it anytime soon. Obviously, buying a quad core processor is going to be significantly faster than a dual-core, and your browser is usually less resource intensive than many other programs. I wouldn't use it as your purchasing decision. Firefox will run equally well on a dual-core or a quad-core, but windows and other programs will run better with 4 cores.

DbEnv under mod_perl 2.0/Apache 2.2 worker MPM (multi-threaded)

I'd like to draw your attention to a thread I've opened on the mod_perl mailing list. I'm having difficulties figuring out how to initialize the Berkeley database environment on this particular platform. It may be that mod_perl is not the most suitable choice of platform for developing an application working on Berkeley DB, but still I'm curious to know whether or not this is at all possible, and if not, what are the reasons for this mismatch.
Note that I'm actually using the Perl interface to Berkeley DB XML instead of plain Berkeley DB. However, George Feinberg, the DB XML lead developer (I believe), pointed out that the issues I'm seeing pertain to the setup of the database environment, and that once this has been safely accomplished, the DB XML calls are safe, too. That's why he advised me to bring this issue to the attention of the Berkeley DB forum, which I'm now doing. Here we go:
Initializing Sleepycat::DbXml (Berkeley, Oracle) objects in startup.pl | ModPerl
http://www.gossamer-threads.com/lists/modperl/modperl/98849
It may be that a precise answer would require a lot of knowledge of the very particular mod_perl 2.0 multi-threaded platform and its intricacies, which I don't have myself and I know is not commonly found, as Perl has ceded a lot of ground to PHP and Java. But maybe there is someone here who can help.
The fundamental issue here is the setup of the environment. There has to be (1) a thread of control doing recovery on startup, and then (2) any number of threads of control which may or may not share environment handles. How could this be accomplished in this particular environment?
If you're interested in this issue, please follow the link to the mod_perl mailing list and see what's there. Note you can switch between flat and threaded view.
Thanks.

Its been a long time since I messed with this, I ended up using Tomcat standalone, hopefully someone with more experience will reply to you after this post!
But as I remember, it was set up using a wildcard *.jsp to pass JSP files off to tomcat for processing. Apache cannot process jsp, which is why Tomcat is used as a plugin.
The page showing the examples is HTML, whereas the examples themselves are JSP.
Have you told Apache to pass all *.jsp's to Tomcat for PROCESSING.
You are not simply telling apache to open these files, rather Apache tells Tomcat to open and process the files.
Hope this makes sense and is of some use.

Multi-Instrument + Multi-Thread problem found

Right.....I have done a lot of research on why logic was not multi-threading correctly and have narrowed it down to one problem...using Kontakt as a multi instrument.
My Mac is a 2 x 2.26 GHz Quad-Core Intel Xeon. This means that it is capable of distributing work loads over the multiple cores of the CPU to prevent core audio overloads from happening.
If I run any plug ins in stereo or mono mode, the CPU acts as it should; I will load up a program, add processing and when the load is becoming a strain for the CPU, I use a bus send and work on that, then the workload is redistributed across more of the cores by logic, allowing me to continue working.
However, I need to use Kontakt as a multi instrument. I usually have 3 instances of Kontakt open and on each one of these, I usually have a minimum of 10 outputs being sent to the aux channels of logic. Therefore using Kontakt as a stereo instrument is not an option, as I would have to open around 30 instances!
Here is the problem; say for example, in Kontakt I send a kick drum out of Kontakt into AUX 3 + 4. The AUX channel in logic will being to show output. I can now EQ this single kick drum seperate from any other sound in logic.
If I began to add processor heavy plug ins to this AUX output, rather than share the workload across the cores as it should and does with stereo instruments, logic now only uses a single core and it will core audio overload very quickly.
As I said, this only happens when I set up Kontakt as a multi instrument. The main problem is when I begin to have many different outputs from my 3 instances of Kontakt, as by this stage, many different sounds will have processing. All 3 multi instruments and their processing are then controlled by the single processor and the other 7 are almost inactive! It therefore becomes impossible to use Kontakt and I have to switch to stereo instances. This happens for all multi-instruments not just Kontakt.
I have just purchased Kontakt 4, I am upgrading to OSX 10.6 (Snow Leopard) and am updating Logic to v9.1. (From v9.0) Will this help at all? Is there an answer to this problem or will I just have to open 30 stereo and mono instances of Kontakt to continue working!
I have included a link to a ZIP file with two photos of the problem. In the photo named MASSIVE. I have one instance of massive running as a stereo instrument. It is sent to a BUS where I applied the WAVES L316 Limiter. I did this multiple times and if you can see on the system performance (Top right) Logic is sharing the workload over the processors as it should.
In the second picture named KONTAKT MULTI - I have done the same thing, but I have opened Kontakt as a multi instrument, sent a kick drum to AUX 2 and then forwarded this to a send where I applied the same WAVES L316. You can see on the system performance meter (Top Right) that Logic now does not re-distribute the workload, it is using one core and anymore plug ins applied to the AUX or bus channels relating to Kontakt will now make it core audio over load, even though now I am using far less processing.
PHOTOS: http://www.sendspace.com/file/og8a94

Ditto
Using Pro 8 Studio, I had this problem after installing Snow Leopard.
Invested £159 in Pro 9 update, same problem.
This has stopped most of my work since my external WK4 sounds are superior to the included software sounds.
As suggested, will now report since since it obviously seems to be a general problem.

Multi-threaded program hangs in Linux with green thread when doing I/O

Hi,
I am using green thread(jdk1.3.1) on Linux. My program is in multi-threaded model and has some I/O operations. I am runing one java program using Runtime.exec("java <program>"). Actually the <program> prompts user with some question like "enter location" and waits for the input. Now in my code I am constantly reading the input stream of the process. Once I get the string like "enter location", immediately I send the location through Process o/p stream. But the process is not able to read this and hangs there for ever.
Please help, what could be the problem? If you need the source code, pls let me know.
Thanks in advance,
Sisir

I had a similar issue few weeks back... If I could see the source I would have a better understanding of the problem and think I could help out. If you want to send it, send it to [email protected]

Memory leaks and multi threading issues in managed client.

In our company we use a lot of Oracle, and after the release of the managed provider we migrated all applications to it. First the things were very impressive : the new client was faster, but after some days applications that uses 100MB with old client goes to 1GB and up. The memory is not the only issue, we use a lot of multi threading, and we experience connection drops and not disposal, after 1 days working one of the application had over 100 sessions on the server. I think there is something wrong with connection pool and multi threading.
Is someone experience same problems.
Yesterday we went back with unmanaged provider. Now things are back to normal.

connection drops: did you try to use "Validate Connection=true" parameter in your connection string?
the new client was faster: are you sure with this statement? Even in 64bit environment? I got quite serious performance problems when running application under 64bit process: https://forums.oracle.com/thread/2595323

Yes, the MTS for TCP protocol does not work. A patch will be
released soon for the production release with the fix for
the MTS problem.

Multi thread and deadlocks

I am running dataload from a text file to MS SQL SRVR database. The jobs are running in multi thread mode. I am getting deadlock errors with threads.
each thread is supposed to delete records.
with single thread mode log file order is as below
1. get product to be deleted A
2. delete A
3. get product to be deleted B
4. delete B
5. get product to be deleted C
6 delete C
with multi thread mode
1. get product to be deleted A
2. get product to be deleted B
3. get product to be deleted C
4. get product to be deleted D
5. delete A
6. get product to be deleted E
7. get product to be deleted F
8. deadlock while deleteing the product B
Any clues what is going wrong here?
Here is the code for the delete method:
================================
PreparedStatement prepStatement = null;
System.out.println("get product to be deleted " + product);
prepStatement = conn.prepareStatement("delete from MYTABLE where product = ? ");
prepStatement.setString(1, product);
prepStatement.executeUpdate();
================================
Please note that only unique data is sent to each thread.
Any help is greatly appreciated.
Thanks

Thanks for the responses. I need to do update/insert new records after delete operation is completed. Later at the end of the db changes, i close the connection.
From my understanding deadlocks happen when both threads try to touch the same record same time. But, i am sending unique records for each thread. Unless these is somethign wrong with the query, it should always return unique values.
This is the query that sends unique records for each thread in sql srvr.
select distinct top ? columnA, columnB from MyTable where processed = 'FALSE' and columnB = ? "
This should be equivalent of oracle query
select distinct columnA, columnB from MyTable where columnB=? rownum > ? and rownum <= ?
if the top in sql srvr is equivalent to rownum in oracle then i always get distinct records and there should be no deadlocks.
Any help?
Thanks

Enterprise User and Multi Thread Server

Hi,
We are going to build a system which uses a configuration:
10g2
Enterprise User
Multi Thread Server
Client apps accesses db over JDBC/SSL
Could some please share experience about issues regarding
using Enterprise User and Multi Thread Server ?
Is MTS transparant for Enterprise User authentication ?
Regards,
Cezary

If you build simpserv with -t, and set MIN and MAXDISPATCHTHREADS, you
should have an example of a multithreaded server.

on Tuxedo 7.1.
And the impression so far is that apart from the function definitions there is
not much information around.
Didn't even find a simple example of a multi-threaded server in the Bea refs yet.
Does anyone know/have such an example?
And is anyone using multi-contexting in a server, because the limitation that
only server-dispatched
thread get a context puts quite a limitation on its usefullness.

Aggregate Storage And Multi-Threading/Multi-Core Systems

Please pardon if this question has been asked before, but the Forum search is not returning any relevant results.
We are in the process of purchasing hardware for an 11.1.2 Essbase environment. We are going 64-bit, on Windows 2008, with either 32 GB or 64 GB of system RAM. The debate we are having is the number of CPUs and cores per CPU. We have not built any ASO databases as of yet, but we plan to launch a major BSO to ASO conversion project once 11.1.2 is off the ground here.
Historically, with BSO, we did not see performance improvements significant enough to justify the cost of additional CPUs when we ran calcs on multi-CPU systems vs. single or dual CPU systems, even when the settings and design should have taken the most advantage of BSO's multi-threading capabilities. However, it would seem that ASO's design may be able to make better use of multi-core systems.
I know that there are a lot of factors behind any system's performance, but in general, is ASO in 11.1.2 written well enough to make it worthwhile to consider, say, a four CPU, total 16 core system vs. a 2 CPU, total four core system?

Grand central dispatch - infancy, not really doing its job, and I don't think apps have to be specifically written for HT, but they do have to not do things that they use to - prevent threads from going to sleep! or be parked.
high usage is not necessarily high efficiency. often the opposite.
Windows 7 seems to be optimized for multi-core thanks to a lot of reworking. Intel wants and knows it isn't possible to hand code, that the hardware has to be smarter, too. But the OS has a job, and right now I don't think it does it properly. Or handle memory.
Gulftown's 12MB cache will help, and over all should be 20% more efficient doing its work.
With dual processors, and it doesn't look like there are two quick path bridges, data shuffling has led to memory thrashing. Use to be page thrashing with not enough memory. Then core thrashing but having the cores, but not integrated (2008 is often touted as being greatest design so far, but it was FOUR dual-cores, 2009 was the first with a processor that really was new design and (native) 4-core.
One core should be owned by the OS so it is always available for its own work and housekeeping.
The iTunes audio bug last year showed how damaging and not to implement code and how a thread could usurp processing and add a high cpu temperature while basically doing nothing, sort of a denial of service attack on the processor - those 80*C temps people had.
All those new technology features under development and not like OpenCL, GCD and even OpenGL are tested, mature but rather 1.0 foundation for the future. A year ahead of readiness.
