How to reduce CPU utilization time in Java Application

Hi,
I have created a Java Application. It is a 3-tier architecture. While running my Java application, the CPU utilization percentage shots up to 100 %. I feel that it will affect the system performance and it will hang up the system also.
If any body know the solution to reduce the CPU utilization or links, please post it.
Thanks in advance.

I know Java class file must be interpreted by VM. but
Visual Basic is also a language to be interpreted. Why
it run faster than Java? As Java running speed is
concerned, it's unwise to apply to the
enterprise-level application. Now I can't endure Java
running speed. I wander to know whether it is
associated with operating system or not.1. Java is nto interpreted in modern (since 1997 or earlier) JVM's - it is compiled into machine code as it is executed via a JIT or a Dynamic compiler (like HotSpot).
2. VB (5 and later) is also not truely interpreted - in fact it uses the same excellent native code generator used by Visual C++.
3. Java is principally used these days for enterprise server-based systems where it performs extremely well - or extremely poorly as does C++ in the hands of people who don't know how to use it.
4. Different JVM's (and in some cases the same JVM hosted on different OS's) perform at different speeds - your mileage will vary. The OS has little influence on the computational speed of java but can highly influence its network, disk and graphics performance, as does hardware configuration (local console versus X terminal - Swing sucks on X Term).

How to reduce Post-Processing time in oracle applications R12?

Hi All,
I ran a XMLP concurrent program at 16-APR-2015 11:23:52 . It's completed at 16-APR-2015 11:30:41. So it took 6 minute 49 seconds. I check the query in sql developer, it's executing less than two minutes. When I check the log file of that program shows the following info...
Beginning post-processing of request 22226009 on node DEV at 16-APR-2015 11:24:43.
Post-processing of request 22226009 completed at 16-APR-2015 11:30:41.
So what is the reason?, and how to reduce the time?

HTML is a simple format (Text).
Excel is more complicated and requires more time to generate. The same applies for Word and PDF output.
Maybe the processing power and memory of the server are not high and this does not help generate the output faster.
I have a workaround for you, generate an XML file (which should finish faster) and open it in Excel.

How is GC cpu utilization % calculated?

I am trying to find a way to capture the problem where a user process eats up a ton of cpu for over 30 minutes. I thought that I could possibly use the cpu utilization metric.
In testing it, I reset the values to warning and critical thresholds to 0 and 5% respectively to see what would happen. I was emailed with the expected critical alert. In looking at the top sessions on the server, I noticed that 1 session was eating up 100% of one cpu (which I want to know about) but the alert email said that 45% was utilized which I noticed was about what the user load is on the server.
Initially, I had the warning and critical threshold set to 85 and 95% respectively but did not get any warning about a user process that was taking up 100% cpu for > 5 minutes (in which the 5 minute collect times were set to once).
My questions are
1) How do I capture a single process eating up > 90% cpu in a multi-cpu environment
2) Is the cpu utilization % capturing the Average Load of the cpus on the server and alerting when it's above the critical threshold?
3) How is the cpu utilization % calculated?
Help would be appreciated.

The cpu load is determined by running the Grid program nmupm found in $AGENT_HOME/bin
The output is like:
dbc12ykf: PDBGRP> nmupm osCpuUsage
em_result=1|206331806.000000|201540370.000000|102524043.000000|958620752.000000
em_result=2|212731589.000000|201203614.000000|67775500.000000|948506267.000000
em_result=3|212402913.000000|230642957.000000|76833167.000000|917779040.000000
em_result=4|242543014.000000|367865067.000000|81554006.000000|791426607.000000
You will get a line for each cpu.
YOu'll need a bit of reverse engineering to figure out the columns - I think they are user, system, idle , 5min avg - Multiplied by 10000 ?
Now to capture a big one - I think you will need a user defined metric. Just write a simple shell script to run the above command, and evaluate the numbers coming thru.

How to reduce dso activation time

hi
can any body explain me how to reduce dso activation time.I am having a dso with 5 crore records and it is taking 7 to 8 hrs for activation.

Hi,
Try this.
T.code RSCUSTA2 . Here you can change the no.of records and no.of processes to use for activation job with this you can increase your ODS activation process, here the no.of processes can be increased based on no.of processes available in your server, check in SM50 or SM51.

How to reduce the size of cloned Oracle Applications Instance

How to reduce the size of cloned Oracle applications instance, so as to save the storage space for the cloned systems.
How can we remove unimplemented modules in the instance so that we can reclaim the space occupied by them.
can any please suggest on this..?

mumbai,
I would recommend to leave it as it is.
If you can add some inexpensive HDD to your test system then do so.
The Apps DB storage decreasing process is quite painful and isn't straightforward.
You cant just delete unused schemas & tablesapces (if they are not used than they are not consuming reasonable space anyway). The modules in Apps are using each other procedures and objects. The effect of deleting one module (schema) is highly unpredictable.
If you will do something like that than you will not be able to patch your cloned system after that.
Some things can be done however in order to reduce size of a testing Apps system:
- Decries UNDO & TEMP tablespaces. Normally you do not need that big tbs in test system as you have got in the production.
- If your REDO LOG files are quite big and you have got a lot of redo groups you can recreated smaller REDO log files.
- On Apps tier you can delete OUTput and LOG files
In case you still would like to decrease data volume in your testing system you need to take a look on some tools which provide data subtracting capabilities from Apps DB. This process has to be quite intelligent. The tool have to know the data structures in APPS DB and subtract data in the way to not harm logical relationships between records. After a subtracting process you will need to make multiple FULL exp/imp cycles in order to reduce physical space consumed by the database. Beside the fact that those tools are quite expensive you will need to spend a lot of your time to implement those.
BTW: That is the size of you production DB? Have you analyzed which module takes most of the space? May be you can identify top 10 objects and try to archive a data from those object preventing the future grow of the production database.
Just my 0.02£

How to create a Batch file for java application ?

HI,
How to create a Batch file for java application ?
And whats the use of creating batch file ?
Thanks in advance

[http://static.springsource.org/spring-batch/]
Assuming you want to develop a batch application rather than actually just create a .bat file ..

HOw to create a Batch file for java application and whats the use of this ?

HI,
How to create a Batch file for java application ?
And whats the use of creating batch file ?
Thanks in advance

First of all, you're OT.
Second, you can find this everywhere in the net.
If you got a manifest declaring main class (an classpath if needed), just create a file named whatever.bat, within same directory of jar file, containing:
javaw -jar ./WhateverTheNameOfYourJarIs.jar %*By the way, assuming a Windows OS, you can just double click the jar file (no batch is needed).
Otherwise use:
javaw -cp listOfJarsAndDirectoriesSeparedBySemiColon country/company/application/package/className %*Where 'country/company/application/package/' just stands for a package path using '/' as separator instead of '.'
Don't specify the .class extension.
Javaw only works on Windows (you asked for batch, I assumed .BAT, no .sh), in Linux please use java.exe (path may be needed, Windows doesn't need it 'cause java's executables are copied to system32 folder in order to be always available, see PATH environment variable if you don't know what I'm talking about) and use ':' as classpath (cp) separator.
The '%***' tail is there in order to pass all parameters, it only works on Windows, refer to your shell docs for other OSs (something like $* may work).
This way you have a command you can call to launch your code (instead of opening NetBeans just to see your app working). You could schedule tasks on it or just call it in any command prompt (hope you know what it is 'cause there have been people in this very same forum with no clue about it, if not just hold the 'Windows button' and press 'R', then type 'cmd' and run it).
Finally add dukes and give 'hem away.
Bye.

How to deploy a POJO or a java application in oracle ESB?

hi,
I m beginner in oracle ESB.
please someone tell me how to deploy a POJO or a java application in oracle ESB?
thank you.
Peter.

The short answer is "you wouldn't"
The long answer is that you would expose your Java Application or POJO as a Web Service then virtualise it through the ESB.
If you're wanting to learn more about SOA, ESB and BPEL have you been to this site http://download.oracle.com/docs/cd/B31017_01/index.htm

How to create the exe files for java application

How to create the exe file for java application?
got any software to do that?
Thanks

In terms of converting java applications into exe files, there are 3 schools of thought:
1) Instead of converting it to an exe, convert it to a jar file. Jar files are more portable than exe files because they can be double-clicked on any operating system. The caveat is that a Java interpreter must be installed on the target computer for the double-clicking to work.
http://developer.java.sun.com/developer/Books/javaprogramming/JAR/
2) Create an exe launcher that, when double-clicked, attempts to find a Java interpreter on the local computer and launches the Java application. The exe file is still double-clickable but whether your java application runs depends on whether a Java interpretor is installed on the target computer.

http://www.jelude.cjb.net/
http://thor.prohosting.com/~dfolly/java/index.html
3) Create an exe launcher that bundles a Java interpretor. Same as above but when the exe file is double-clicked, it searches for a Java interpreter and if one is not found, it installs one on the target computer. The caveat is that the exe file would have an overhead of 10 MB in size for the interpreter.
http://www.excelsior-usa.com/jet.html (evaluation version available)
4) Convert the Java application into a native exe file. The caveat is that if you use Swing for your GUI, it won't be converted. Also this option is still somewhat experimental.
Can't think of any free options right now.

The best place to ask your question is at the JSMS website, forum or mailing list since this is no error that directly comes from a class belonging to the core Java classes.
