Thread prioritization for better Player performance?

I have been developing an application to capture individual frames from a video clip on disk. I have implemented a Processor to load and play the video and inserted a custom Codec as a video track control to capture the frames. The code is fairly simple and hasn't changed since I have implemented it.
A noticable degradation in performance has shown up now that the rest of my application has increased in complexity. The video is choppy and often falls out of synch with the audio track. Is there a way for me to prioritize the JMF thread(s) in such a way to make it unaffected by the rest of my application's threads?
Thank you for reading this post.

I have increased the priority of the thread used in my Codec but have only noticed a marginal improvement in video playback. The audio track still skips at times. I have even decreased the priority of the other threads in my application but this seems to have little effect. I have the feeling I am not prioritizing the right thread(s)... How does one access the many threads used by the JMF in playing back a clip using a Processor object?

Upgrading for better gaming performance.

Hey everyone,
     I recently received this latop for Christmas. I really enjoy all around gaming from PC to Console. The problem that I am having is mostly on WoW. I ran the system via systemrequirementslab.com (the can you run this section) and it told me that I had the minimum requirements capable of running. For a few days it worked phenomenally but most recently the game slows to a crawl to the point that it takes 15+ minutes before I get two minutes of movement. Is there anything I can do to upgrade my laptop and run videogames better?
This question was solved.

What are the better load/performance testing tools available for Flex Application with BlazeDS RO?

In my application is designed with Flex3, ActionScript3, BlazeDS Remote Objects.
Just i tried with OPENSTA but i cant do the dynamic parameterization in their generated scripts because the response of the calls is binary values and also we cant get the response using with SCL language.
While testing with OPENSTA with HttpService, i can do the dynamic parameterization and got the response.
can give the information about the below questions
whether we can do dynamic parameterization with OPENSTA for Flex Remote objects?
and what are the better load/performance tools available for Flex Remote Objects?

Your approach is fine, depending on how many and what type of CFCs you are talking about. If they are "singletons" - that is, only one instance of each CFC is needed to be in memory and can be reused/shared from multiple parts of your application - caching them in the application scope is common. Just make sure they are thread safe ("var" or local.* all your method variables).
You might consider taking advantage of a dependency injection framework, such as DI/1 (part of the FW/1 MVC framework), ColdSpring, or WireBox (a module of the ColdBox platform that can be used independently). They have mechanisms for handling and caching singletons. Then you wouldn't have to go to the application scope to get your CFC instances.

I need a clarification : Can I use EJBs instead of helper classes for better performance and less network traffic?

My application was designed based on MVC Architecture. But I made some changes to HMV base on my requirements. Servlet invoke helper classes, helper class uses EJBs to communicate with the database. Jsps also uses EJBs to backtrack the results.
I have two EJBs(Stateless), one Servlet, nearly 70 helperclasses, and nearly 800 jsps. Servlet acts as Controler and all database transactions done through EJBs only. Helper classes are having business logic. Based on the request relevant helper classed is invoked by the Servlet, and all database transactions are done through EJBs. Session scope is 'Page' only.
Now I am planning to use EJBs(for business logic) instead on Helper Classes. But before going to do that I need some clarification regarding Network traffic and for better usage of Container resources.
Please suggest me which method (is Helper classes or Using EJBs) is perferable
1) to get better performance and.
2) for less network traffic
3) for better container resource utilization
I thought if I use EJBs, then the network traffic will increase. Because every time it make a remote call to EJBs.
Please give detailed explanation.
thank you,
sudheer

Please suggest me which method (is Helper classes or Using EJBs) is perferable :
1) to get better performance
EJB's have quite a lot of overhead associated with them to support transactions and remoteability. A non-EJB helper class will almost always outperform an EJB. Often considerably. If you plan on making your 70 helper classes EJB's you should expect to see a dramatic decrease in maximum throughput.
2) for less network traffic
There should be no difference. Both architectures will probably make the exact same JDBC calls from the RDBMS's perspective. And since the EJB's and JSP's are co-located there won't be any other additional overhead there either. (You are co-locating your JSP's and EJB's, aren't you?)
3) for better container resource utilization
Again, the EJB version will consume a lot more container resources.

DO's & DONT's for a better application performance

I am very new to tuning. What are the sql & pl/sql do's and dont's and best sql & pl/sql practices for a better application performance?
I was told by somebody to check explain plan for tuning db & sql statements. But i am bit confused by seeing the explain and don't know from where i have start and what i have take into consideration from explain plan to improve application preformance?
Can somebody help me in this regard?

> I am very new to tuning.
Good. Not having to tune means that the code is performing as it should.
And this is THE MOST IMPORTANT CONSIDERATION.
Do not write and design code that needs to be tuned and twisted and modded in order to perform. Write and design code with the core requirements of that code being:
- performance
- scalability
- flexibility
- maintainability
Good design = good code = good performance
No amount of tuning can turn bad code and a bad design into a well performing and scalable system. Which is why I dislike the concept of "tuning code". Start with a good and solid design. In other words, tune that before the code.
> What are the sql & pl/sql do's and dont's and best sql & pl/sql practices
for a better application performance?
The 1st basic rule is actually quite simple.
The "data layer" rule: Maximize SQL. Minimize PL/SQL.
Do not do in PL/SQL what SQL is very capable of doing. Fact. No other language is faster and better than SQL at crunching data in the Oracle RDBMS.
The 2nd basic rule is a logical extension of the 1st.
The "application layer" rule. Maximize PL/SQL. Minimize Java/C++/C#/Delphi/VB/etc.
Do not do in a 3rd party language what PL/SQL is extremely capable of doing. Fact. No 3rd party language is as capable as crunching data in the Oracle RDBMS as PL/SQL.
Stick to these two fundamental rules and your Oracle application will have a solid foundation for being a well performing and very scalable solution.

Just trying to get a definitive answer to the question of can we use a Shared VHDX in a SOFS Cluster which will be used to store VHDX files?
We have a 2012 R2 RDS Solution and store the User Profile Disks (UPD) on a SOFS Cluster that uses "traditional" storage from a SAN. We are planning on creating a new SOFS Cluster and wondered if we can use a shared VHDX instead of CSV as the storage that
will then be used to store the UPDs (one VHDX file per user).
Cheers for now
Russell
Sure you can do it. See:
Deploy a Guest Cluster Using a Shared Virtual Hard Disk
http://technet.microsoft.com/en-us/library/dn265980.aspx
Scenario 2: Hyper-V failover cluster using file-based storage in a separate Scale-Out File Server
This scenario uses Server Message Block (SMB) file-based storage as the location of the shared .vhdx files. You must deploy a Scale-Out File Server and create an SMB file share as the storage location. You also need a separate Hyper-V failover cluster.
The following table describes the physical host prerequisites.
Cluster Type
Requirements
Scale-Out File Server
At least two servers that are running Windows Server 2012 R2.
The servers must be members of the same Active Directory domain.
The servers must meet the requirements for failover clustering.
For more information, see Failover Clustering Hardware Requirements and Storage Options and Validate
Hardware for a Failover Cluster.
The servers must have access to block-level storage, which you can add as shared storage to the physical cluster. This storage can be iSCSI, Fibre Channel, SAS, or clustered storage spaces that use a set of shared SAS JBOD enclosures.
StarWind VSAN [Virtual SAN] clusters Hyper-V without SAS, Fibre Channel, SMB 3.0 or iSCSI, uses Ethernet to mirror internally mounted SATA disks between hosts.

Multi-threaded transactions for performance reasons

Hi,
I need to be able to perform a number (20 - 30) reads and updates from \ to
a huge (500 million records) Oracle database within the same transaction
context within a set time limit. In order to meet the time limit I suspect I
may need to perform a lot of the SQL operations in parallel. I'm using
weblogic version 7 and Oracle 8.1.7 on hardware with a huge number of CPUs..
a) Ideally I would like to do this using the standard EJB bean components
but can't think of a possible way of doing it. Is there any way to do this
while executing within the scope of an EJB container?
b) Assuming the answer to a is no, could I do it by invoking an RMI server
which could then set up a UserTransaction in a controlling thread and start
a number of SQL slave threads (hopefully inheriting the parent threads
transaction context). The controlling thread could then wait for the slave
threads to finish before commiting. Hopefully though the slave threads would
get the chance to perform a setRollbackOnly if anything went wrong.
c) It the answer to b above is yes would there be any problem invoking the
RMI server from within a session bean. For example would the transaction
context of the session bean affect the behaviour of the RMI server and is it
legal to create threads in the RMI server even though it is invoked from a
session bean?
Thanks for any help in advance.

Oracle doesn't want you using threads in the Java Stored Procedures in the
database. If you read on a bit further in the Oracle doc, you come to this
passage at :
http://otn.oracle.com/docs/products/oracle9i/doc_library/release2/java.920/a96659/01_intro.htm#21254
<quote>
As a database server, Oracle9i efficiently schedules work for thousands of
users. The Oracle JVM uses the facilities of the RDBMS server to concurrently
schedule Java execution for thousands of users. Although Oracle9i supports Java
language level threads required by the Java Language Specification (JLS) and
Java Compatibility Kit (JCK), using threads within the scope of the database
will not increase your scalability. Using the embedded scalability of the
database eliminates the need for writing multithreaded Java servers. You should
use the database's facilities for scheduling users by writing single-threaded
Java applications. The database will take care of the scheduling between each
application; thus, you achieve scalability without having to manage threads. You
can still write multithreaded Java applications, but multiple Java threads will
not increase your server's performance.
</quote>
So, YMMV if you spawn your own threads in the Oracle JVM.

Chris,
I'm not sure this fits your problem, but you may investigate
writing a Oracle stored procedure in java. I believe its possible
to use threading inside that procedure to perform your concurrent reads /
updates.
I haven't done this personally and I forsee many hurdles (just brain
storming).
From the Oracle 8.1.6 Docs
"The JServer JVM provides a run-time environment for Java objects. It fully
supports Java data structures, method dispatch, exception handling, and
language-level threads. It also supports all the core Java class libraries
including java.lang, java.io, java.net, java.math, and java.util"
Something else to consider is Message Driven Beans (although this would
violate your same transaction context requirement) and combining the results
would be challenging.
Any of your WLS side solutions are going to be problematic, because I
believe that
there is a JDBC restriction that a transaction can only have one outstanding
SQL call.
You might get around this on the DB side by managing a pool of
sub-transactions in a stored procedure
and have your managing thread commit or rollback all sub-transactions.
Any possiblity of doing some SQL magic and combining several reads into one
or setting up a View to do this for you?

Please help to modifiy this query for better performance

Please help to rewrite this query for better performance. This is taking long time to execute.
Table t_t_bil_bil_cycle_change contains 1200000 rows and table t_acctnumberTab countains 200000 rows.
I have created index on ACCOUNT_ID
Query is shown below
update rbabu.t_t_bil_bil_cycle_change a
   set account_number =
       ( select distinct b.account_number
         from rbabu.t_acctnumberTab b
         where a.account_id = b.account_id
Table structure is shown below
SQL> DESC t_acctnumberTab;
Name           Type         Nullable Default Comments
ACCOUNT_ID     NUMBER(10)
ACCOUNT_NUMBER VARCHAR2(24)
SQL> DESC t_t_bil_bil_cycle_change;
Name                    Type         Nullable Default Comments
ACCOUNT_ID              NUMBER(10)
ACCOUNT_NUMBER          VARCHAR2(24) Y

Ishan's solution is good. I would avoid updating rows which already have the right value - it's a waste of time.
You should have a UNIQUE or PRIMARY KEY constraint on t_acctnumberTab.account_id
merge rbabu.t_t_bil_bil_cycle_change a
using
      ( select distinct account_number, account_id
from rbabu.t_acctnumberTab
      ) t
on    ( a.account_id = b.account_id
       and decode(a.account_number, b.account_number, 0, 1) = 1
when matched then
update set a.account_number = b.account_number

What is the best way to replace the Inline Views for better performance ?

I am using Oracle 9i ,

Please suggest.

WITH plus /*+ MATERIALIZE */ hint can do good to you.
see below the test case.
SQL> create table hx_my_tbl as select level id, 'karthick' name from dual connect by level <= 5
2 /
Table created.
SQL> insert into hx_my_tbl select level id, 'vimal' name from dual connect by level <= 5
2 /
5 rows created.
SQL> create index hx_my_tbl_idx on hx_my_tbl(id)
2 /
Index created.
SQL> commit;
Commit complete.
SQL> exec dbms_stats.gather_table_stats(user,'hx_my_tbl',cascade=>true)
PL/SQL procedure successfully completed.
Now this a normal inline view
SQL> select a.id, b.id, a.name, b.name
2 from (select id, name from hx_my_tbl where id = 1) a,
3 (select id, name from hx_my_tbl where id = 1) b

My mac says connect to a faster usb for better performance

every time i connect my ipod the mac says:
the ipod is connected to a low-speed USB 1.1 port. for better performance, you should connect it to a high-speed USB 2.0 port if one is available on your computer
whats that about

It means exactly what it says.
This message will pop up when you connect a device (the iPod) that works with USB 2.0, to USB 1.1 port.
USB 1.1 is 12 megabits per second.
USB 2.0 is 460 megabits per second (60 ttimes faster).
For better perfomrance, use a usb 2.0 port if your computer has one.
Unfortunately, your iBook G3 does not have USB 2.0.

The activex controls for flash player could not be registered

the activex controls for flash player could not be registered
i have had this problem for a while and cannot seem to get around it please post anyreliable suggestions

Just to add some additional misery to this thread. I have this exact same issue. Windows 7.
The issue started several weeks ago, when a flash update failed to install. Everything seemed fine other than every reboot, this flash update would fail (and in fact would "hang"), but flash itself continued to work.
Yesterday, it stopped completely. It said flash wasn't installed. I've tried:
1. Completely uninstalling flash (it is not in Add/remove programs) but using the techniques and videos offered by Adobe to remove the files, using their uninstaller, etc.
2. Perform the fix as outlined in http://forums.adobe.com/thread/987370 which including installing SubACL, the batch file, etc. The batch file ran successfully, but did not solve the problem.
3. I've tried Windows System restore, but it doesn't seem to go back far enough.
4. I've tried the fixit identifed above in this thread and while it solves certain problems, still doesn't solve my issue.
5. I've tried installing using the stand alone EXE and MSI from Adobe.
6. I've tried the 11.9 beta.
None of these have worked and all result in the "failed to register" error. I'm currently using the flash built into Google Chrome as I needed to have some working flash component.
Anyone else have any ideas whatsoever short of a Windows reinstallation?

"the activex control for flash player could not be registered" - Solutions Roundup

I recently ran into this problem on my computer:
http://at32.s3.amazonaws.com/flash_install_problems2.jpg
I am a Flash developer (as in I write SWFs, I don't work for Adobe). and when I updated IE to 10.2, "the activex control for flash player could not be registered". Since I am a developer, I also have Firefox and Chrome installed, with Flash running without problems. For a long time now, Internet Explorer has used a different version (ActiveX) to the other browsers, which use plugins. I am a strong supporter of Flash, it's great to develop with and has a very wide feature set which is growing all the time, unlike fixed technologies/standards. However, the weakest part is the install process - I don't understand why their is a Download Manager. Google Chrome does it's best (so far) by managing the install/update process entirely in the background. Anyway, it was in my best interest to try and get to the bottom of this.
For the record, on the problem machine I have Windows 7 with IE8, but I have seen almost identical symptoms with IE9, Windows XP SP3, as well as various iterations of Flash Player (10.0, 10.1, 10.2 and even some final editions of version 9).
First I tried the standard support here:
http://kb2.adobe.com/cps/191/tn_19166.html
Basically, doing the manual uninstall and manual install of the latest version (without using the download manager, or have IE open). This did not work. I also tried the Microsoft "subinacl" program, together with "reset_fp10.bat". This didn't work either. However, you should try all of these things first before progressing further.
A quick note about people who had tried running the following at a command prompt: "secedit /configure /cfg %windir%\repair\secsetup.inf /db secsetup.sdb /verbose"
I didn't do this, because on investigating further it didn't seem to work with Windows 7, only Windows XP, Windows 2000 or Windows 2003 - though there was a few threads where this had fixed the problem for some users.
For my solution, it is recommended you use the manual uninstall / installers, so you should have them downloaded ready to use.
I then heard about problems with permissions in the registry with the key: HKEY_LOCAL_MACHINE\Software\Classes\shockwaveflash.shockwave
So I opened regedit.exe (start - run - typed "regedit.exe"), navigated to the key and sure enough, I couldn't open it - permission denied - even though I had an administrator account. If for some reason, you can access this key (and any subkeys), then it's likely the following fix will not resolve the problem.
I then done further diagnosis, by using Process Monitor to try and install Flash Player, and I got the following:
http://at32.s3.amazonaws.com/flash_install_problems.gif
This shows all the access denied errors the Flash Player install was experiencing when trying to write to the registry key. This confirmed that this was the problem. I only stress this because several people said it was unwise to tinker with the registry. Though this is common advice, this is the only known fix for this precise problem at present, since you need to manually adjust the permissions yourself. I don't know who is at fault here - Microsoft or Adobe - but let's just get Flash fixed...
The solution:
Firstly, you may want to backup your registry, or the exact key. I didn't do this so I've provided no instructions on how to, but it is recommended for the paranoid. Also make sure as much software is closed down as possible - browsers, IM software, any junk in your system tray. As way of example, I happened to have "BBC iPlayer" installed and running in the background which uses Adobe AIR and Flash Player, so I exited that too.
1) Open regedit (start - run - type "regedit.exe"). You may need to right click on it and select "Run As Administrator", but I didn't as my account was already administrator.
2) Navigate to the key. HKEY_LOCAL_MACHINE\Software\Classes\shockwaveflash.shockwave
Click on it to confirm that you cannot access it (you will get an error) - if their are no problems - this probably isn't the cause of your issues.
3) Right click on it and click Permissions, and ignore any message that may pop up.
4) Under "Group or Usernames" click "Add". Type your account name name, or "Administrators" in the box, then "Check Names" to format it correctly, then Ok.
5) Now on the next screen click the checkbox to enable Full Control (this will also automatically enable "Read" permission too).
6) Click Advanced, then the "Owner" tab at the top. You will see that their is no "Current Owner". This is what we will now fix.
7) Click on your name to change the owner to (I went for Administrators). Also enable the checkbox entitled "Replace Owner on subcontainers and objects". Then click Ok. You will get an error message, which you can try clicking Retry to, but hit Cancel - this is not a problem.
8) Click Ok a couple of times and this part of your registry is now fixed.
9) Now it's a simple case of running the manual Flash uninstall program, then finally the manual Flash installer (for Active X - not the Firefox/Chrome plugin versions). To my surprise, after a couple of days looking into this - I finally had a solution and Flash in IE once more. If you are using Firefox too you may find Flash is no longer installed their (the uninstaller removed it). In this case just install via the Adobe site or try to watch a video on You Tube and you will be prompted or linked to the install.
Hope this provides a good round up of the possible solutions to this problem. Hopefully Microsoft or Adobe can find out what causes this issue in the first place so we don't have to go down this route for much longer. Chrome's implementation of Flash shows how effortlessly things can work!

They will stay on the screen. However, Process Monitor is only intended for advanced users. It is recommended that users try to navigate to the troublesome registry key using regedit, and see if they can access it or not without an error. This is far easier than trying to use Process Monitor, which is very complicated.
I used Process Monitor to confirm that it was just that key which was causing the problem, and not others. Process Monitor is not to be confused with the new Resource Monitor which is accessible via Task Manager in Windows 7 (and possibly Vista). If you must experiment (and Process Monitor is very useful for diagnosing many deep-level problems if you know what you're looking for) Process Monitor can be downloaded from here:
http://technet.microsoft.com/en-us/sysinternals/bb896645
It replaces the older Sysinternals "FileMon" and "RegMon". For those interested in the technical side, I had to setup a number of filters to be able to get the results display as in the screenshot. First of all to just show Registry events. Then to just show events from the manual Flash activeX installer executable. The I added a filter to show only non-successfull results. And finally, for the purposes of the screenshot, added a filter to just show those with "Access Denied", since other non-critical errors are also picked up due to missing keys because installation has not yet been fully completed I guess. When experimenting, most of these filters were applied using the "is not" boolean logic, which will make sense if you experiment with the program.
Without adding any filters, it picks up so many events (hundreds per second) that it's otherwise unusable. e.g. 40,000 events within the first few seconds of opening the program. For this reason, I recommend simply using Regedit to diagnose the problem with the particular Flash registry key.

Cardbus VGA for better performance?

In the past, was some special designed VGA card (by the IBM, too). Some of these could connect to the PC through the cardbus interface. Anyway, I am not an engineer. So I do not know this is possible or not. But I can imagine a special cardbus VGA which can improve the standard netbooks graphical performance. The netbooks are a special part of the PCs - I know - with poor graphical performance. This is a fact. I read in an article that, about 30% of netbooks returned to the merchants because the owners were not satisfied with them. So, I think that, my imagine is not a folly. If I know well, the cardbus slot of Lenovo netbooks have PCI-E 1x interface which is equals about the speed of an AGP 8x interface. I think that, this is enough for a better graphical performance, if the GPU has real power. I think the philosophy of PCs something similar: Build your PC for what you want! I know that too, the netbooks with ION platform will arrive soon. But this is the future and many people have a netbook in the present. Maybe some of them would be happy if they could upgrade their netbooks. I like my netbook, but I could like better if I could upgrade it.
Sorry, for my English, I hope that was understandable what I would like to ask.

Thank you for the answer! If the spec that you are linking to is the latest then my measurements are not that far from the "typical" curve showed in figure 1. The spec that I have is more optimistic, showing a flat curve all the way up to 200kHz. The 50 dB that you are talking about is specified when the channels are used in unbalanced differential mode. This means that one signal is applied to the "shield" of the coaxial cable, giving the 5922 two differential channels. I want to verify the CMRR when two channels are used as one "real" differential channel and the CMRR for that is in figure 1. Best RegardsStefan Johansson
