Application Server - Slow

Hi,
We are facing a problem with my Oracle Application server interms of perfomance during peak hours. We are using Itanium processor with 2 CPU and 8g memory. To my surprise neither CPU nor memory is utilized even to 50% but all users are complaining for system poor perfomance.
OS= Windows 2003 EE Service pack 2 HP Server rx3600 Itanium proc 64bit.
Forms based Apps server.
We would like to know what % of memory/CPU is allocated to the Application server and if any furthe tuning we can do to improve perfomance.
Regards,

There can be many reasons, start with this checklist:
* network connection between the servers, and between the client and the app server
* queries execution time
* queries count on requests
* script execution time
* requests count on a page (for static and dynamic content)
1st:For network connection,ask the user's to ping on the server
eg:"ping -t server ip address"
check the response time..it should be between 1ms -60ms..i it is greater then this try to increase the bandwidth of the network.
have tuned your application server??
Regards

  • Slow start-up for JSF projects on Sun Java System Application Server 8.2?

    App. Server: Sun Java System Application Server 8.2
    I really don't understand why a JSF project starts-up so slow on Sun Java System Application Server 8.2.
    I've gone through the "Overview of Sun Java System Application Server Performance" guide and tuned my server.
    It's not memory or processor, I am developing on a SunOS 5.8 Generic_117350-27 sun4u sparc SUNW,UltraAX-MP.
    The JSF project contains one index.jsp and one login.faces - that's it. But it takes up towards 15 seconds to load the page, if I type:
    http://<domain>:8080/login/
    I would believe that the application should be a lot faster.
    What can I do to solve this?
    Thanks,

  • Slow application server

    hi,
    i have oracle application server 10g on windows 2000 server, my server is working very slow how to speed it fast ?
    how to tune it plz tell me .

    Wow! this is pretty broad/open ended questions so I can only give you a broad answer. The first place to start will be Oracle Application Server Performance Guide.
    10.1.3 guide is here:

  • Slow performance of Application server with a 9i database.

    I am experiencing extremely slow perrformance of my 1.0.2.2.2 Application Server portal with my 9.0.1.2.1 database.
    After logging in it takes forever just to connect to the Portal home page and even longer using the navigation link to connect to 'my pages'.
    This degradation of performance pretty much happened over night. One day it was fine and the next it seemed to hang on every movement.
    My server is running on Win 2000 with 1 GB of RAM. I ordered another GB of RAM hoping to alleviate a little of the congestion. I think it must hhave something to do with all the indexes, but I don't know how to tune the DB for it.
    Does anyone have any idea of how to tune the DB to work with the Application Server portal? I am developing this portal for a client and I hate to think what will happen when it becomes fully rolled out and robust.

    I tried to do a simular thing, but I did not notice a performance decrease. However it might be possible that this happens. For example, if you are calling a time critical vi in the second while loop, it will lock all other processes until it is finished. Or maybe you are calling a shared resource (allocate an array, access to a file, using a mutex) that the other loop holds. Until the shared resource is released the first while loop must wait before it can access that resource (memory, file, etc.).
    Without looking at the source code it will be hard to say what is causing it. I recommend to remove part by part subVI's from the second loop, to debug where the problem exists. If you want I can have a look at the code, please reply to this thread.

  • Performance questions in Oracle Forms/Reports of Application Server 10g

    Hello.
    I have a dual Xeon 2.6 computer with 3 GB of memory and 6 GB of cache, running RedHat EL 3 with Oracle AS 10g (9.0.4.0.0).
    Application Server is used to run some applications created with forms, and it generates several reports, but the forms are also used as a front end to another Oracle Database (Oracle 7.0, runing in Sun Solaris 5.6).
    I've notested (and also my users) the application is getting very slow (is running in a dual Xeon, with 2 Gbit nics, in a 3 Gb backbone).
    The speed (or lack of it) is most noted when the forms are generating the reports (it used to be fast - 2 seconds) and now it can take up to 5 minutes.
    The AS 10g, when generating the reports, almost all of the querys go to the other server (in Solaris) and the results return to the server, and then the report is generated. The network has no problems (at least, that i know of), and the network performance is not an issue - both the servers are connected to a Gbit switch.
    Can someone may have an ideia of it can be?
    even in the clients, when running the forms application, the transition of the several menus is slow, and it used to be more fast.
    the 10g is using Java Jinitiator 1.3.18. Can it be from that ? i'm not certain, but i could say this things start happen when we upgraded the jinitiator from 1.3.13 to 1.3.18...
    My users are really getting on my nervers and i cant do nothing, because they have reason...
    any help would be appreciated !
    Cheers
    Bruno Santos

    Bruno, did you solve the performance problem? I'm experiencing the same lack of speed.

  • How to improve the performance of applications in Oracle Application Server 9i ?

    I have my applications deployed to Oracle 8.1.7 database using OSE in Oracle Application Server 9i. My machine has 256 MB RAM. It has both Oracle Application Server and Oracle 8i database server installed on it. When I try running my applications I find they are very slow. Can I get some guidelines using which I can better the performance of my Application? It can be in the form of code, memory ,disk space etc.
    Thanks in advance,
    Regards,

    The system configuration is more than enough to run java applications.
    You are probalbly doing time-consuming operations in the event thread. Which blocks the event thread and the gui seems not to be responding. If you you have a very bad design.
    Use a thread for time consuming operations.

  • Generate Application Server Load Through Siebel Jobs

    I am interested in scheduling a simple job that would tax the CPU of the application server. I can schedule many jobs, such as admin notify, which barely tax the cpu.
    Peoplesoft had some called the simpleAEtest job that I executed on the process scheduler, for a similar need.
    It would be really great If I could configure this job from the command line server manger until,.
    What do you guys do for siebel load balancing and stress testing?
    I have a test siebel Application server environment configured with the following:
    Siebel 8.1.1
    Database Server, Oracle 11g
    Gateway Server, Windows 2003
    Application server, Windows 2003 running the following components
    Callcenter, Sales, and ADM
    There are so many jobs and parameters, its hard to short out what parameters to use.
    Thanks for the help

    Hi Sergiy,
    We currently have the Scheduled Tasks turned off so I know that it is not causing the slow down. I also know that we do not have any custom code that is hitting those tables, as I am the only one that is doing any of the customization.
    However, you bring up an excellent point with regards to other Activities. We have noticed that this does not occur at specific times so that would suggest it was not on some sort of schedule so perhaps a certian Activity is the cause. You mentioned "RMA SFC Receipt", could you find out if there are any other sorts of Activities that may cause this while I look into this one?
    I will perform some tests on our Test machine with the "SQL Trace" and "Debugging Information" turned on as you suggested.
    Thanks,
    Mike

  • Application server components

    Hi, this is the first time i posted here.
    We have a server with 3 application server. Of which the application server's component is scattered around the application servers.
    How do i check which components (forms, reports, etc..) is on which application server?
    Server version: Oracle HTTP Server Powered by Apache/1.3.19 (Unix)
    Server built: Jan 26 2005 11:06:44 (iAS 1.0.2.2.2 rollup 5)
    And also, if the users report that there is slowness on the reports, how do i start to diagnose the problem?
    Thanks in advance for any helps.
    Appreciate it if any links to be provided too.

    Hi,
    if the users report that there is slowness on the reports
    Check the metalink ID : 282170.1
    This will be helpful for ya..
    Also
    Perform the following steps,it should improve the performance of report server to sum extent(first take a backup of
    1)Take the back up and then Edit the reports server's .conf file location $ORACLE_HOME/reports/conf
    For example, change
    <engine id="rwEng" class="oracle.reports.engine.EngineImpl" initEngine="1"
    maxEngine="1" minEngine="0" engLife="50" maxIdle="30" callbackTimeOut="60000">
    into
    <engine id="rwEng" class="oracle.reports.engine.EngineImpl"
    initEngine="4" maxEngine="6" minEngine="3" engLife="50" maxIdle="30" callbackTimeOut="90000"
    jvmOptions="-Xms256m -Xmx512m">
    This will set an Engine's JVM options as well tune ur report server
    How do i check which components (forms, reports, etc..) is on which application server
    Go to directory opmn->bin on each n evry application server and then fire the cmd
    opmnctl status.
    Now if you want to find out on which application server the end user is requesting
    Your client might be accessing the url
    http://<ip-address>:<port>/forms/frmservlet?config=xyz
    Then go to directory forms-->server on each n every application server,n check the formsweb.cfg file n find out where is "xyz" block is been created..
    Note :xyz is just an example..it will be different in ur case

  • Tracing query generated from application server

    Hi all,
    I'm trying to trace a session which is logged in to an application server.
    The application server and database server are in a windows 2003 platform.
    When I'm trying to generate a report from the application server it seems that it generates another session and when I checked on the program column from v$session, it was executed by java.exe.
    There are 2 similiar reports that existed in the application server the other one is really fast and the other one is really slow.
    using the deprecated parameter sql_trace which I can set to true, I can always get the trace file.
    How can I trace that fast generated report that I need to compare with the slow one without using the sql_trace parameter?
    My difficulty is just that when I click on the preview button which is going to preview it to PDF, it will spawn another session and that session will execute java.exe to generate the report.
    May be any of you can give me a suggestion on the things that I need to do with this.
    Regards,
    Adhika

    Hi Finbar,
    for the slow report, I was able to see the session from v$session but for the fast report, even if I prepred the query first before running the report, I don't have enough time to check it.
    it was just to fast. so definitely the fast query has something which is really right so it can generate the query really really fast compare to the slow report.
    FYI, my office is not in the same office as the developer so there's no way I can ask them either and also, there's no way for me to comunicate directly to developer as I need to go through some levels and procedures in my company.
    Thank you,
    Adhika

  • Error when initiating Application Server Jdeveloper

    I am using Oracle Application Server 9.0.3. Simple JSP application is running on it. We are using the application server connection pooling functionality. Following errors are occuring on it frequently and it causes the application server crash.
    First application response gets slow and eventually application server gets lock and it wont respond and we have to restart the application server. Our application is in production mode and we need to solve this issue immediately.

  • About Oracle Application Server 10.1.3.1

    Hi friends,
    I got a software and in its installation guide, it says the software supports Oracle Application Server +10.1.3.1+.
    How could I find where to download a pure Oracle Application Server 10.1.3.1 rather than the SOA suite. The suite is very large and slow. There're many components such as ESB,BPEL,Process Manager which we don't use. But It seems to me I can not find the standard Oracle Application Server 10.1.3.1.
    Would anyone kindly help me about this?
    -Ricky

    when you start the application, you will have to choose the version that not include SOA, for this you will nead a database, if you dont have it you wont be able to install, and if you dont want it, in the installer, you will be ableto choose versions, choose between those that don't include SOA, SOA is 1 of 4 options.
    Regards

  • Could not start Sun Java Application Server

    Hi ,
    I have been using JSC for a while, now and then it reports an error " could not start sun java application server...". Does any one know why it s not able to start java application server..
    Before you say anything, I have tried
    1. use netstat to find any port conflicts.
    2. Tried to start application server manually
    3. shut down and start studio creator and then try running the project
    4. shut down and start PC
    unfortunately none of them helped
    Only reinstalling resolved the problem. But I cant keep reinstalling very often.
    Does any one know the permanent solution for this problem.
    Cheers
    kush

    Sometimes it appears this is a timeout issue because it's taking too long to come up. As Jonathan says, undeploy can help with this (along with his other suggestions).
    How many deployed projects do you see (in the server navigator you can open up the deployed server and see what's out there)?
    I periodically undeploy "junk" projects that I'm not really using because they slow down the server startup (same thing happens I believe for tomcat... when the server starts it has to load them all and it takes awhile). You can undeploy from within the server navigator by drilling into the server nav and right clicking on the deployed app and choosing undeploy... or you can use the server admin tool.

  • Sun Application Server 8 response problem

    Hi forum. I�d installed moths ago SJAS 8 and it woks good. By any reason, I�d to uninstall it. But recently I reinstall te server, without any problem, and I can use teh "Start default server" on the Menu Start. But when I try to access the "localhost:8080", the browser stand hanged. And unusually, any browser in my system (netscape,iexplorer,opera,firefox) won�t work, even to load any site when the Server is working. The option "Stop default server" don�t working too. I�d try install SJAS 8.0, SJAS 8.1 and SJAS 8.1 multilanguaje, but with the same results. Even I�d try change the HTTP port from 8080 to 8282, but nothing happends. Any idea?

    Hi, again. Other details of my installation , The server is SUn Java System Application Server Plataform Edition 8.12005Q1, my machine is an AMD Athlon 1.25Mhz, with 256Mb RAM (Yes, slow for use the server, but it ran without troubles the first time I installed), The JDK is J2SE1.5.0_5 and JRE1.5.0_05. I had read the troubleshotting guide, and the server log register that the server successful finish the start up proccess, and the file domain.xml register correctly the "http-listener" on 8080 port. When I start to search the source of trouble, I remmember that I have the Tomcat 5.5 installed and using the 8080 port, then I uninstall the Tomcat, but the problem persist with the SJAS.

    why its taking time to load?
    any onw knows?

    JVM (java virtual machine) If you have a full stack, infrastructure + BI forms you need 2 gb at least only to install, if you plan to make some work on it it could happen that the computer get very slow.
    In opmn.xml file, in the seccion for the home container (or other you are using) there is a line for Start Parameters, there you have to use the -Xmx1024M to se the maximum JVM size to 1gb, for this you will have to restart the proc.
    For forms also there are some procs where you manage the size of the memory and procs, you can see this in the Configuration Seccion into the EM Console.
