EBS 11i performance problem

Hi hussein, helios, & all,


Happy New Year to you :)
I hope we have a better year 2011 year of the rabbit.
I hope that we have even better in 2011.

I just want to learn something from each of you through the year 2010.

Can you share how tackle you performance problems in EBS?
I know that there is joint action, that you have done to improve performance.
It should be after all statistical analyses of performance as Statspack, SAR,
and other output of the performance monitoring report.

What actions / solutions did you resolve performance issues in EBS?

Is it upgraded the server itself for a more powerful?

For example, our users are complaining about the Oracle Apps very slow race at any time of the day. This produces 20% of the day(performance problem) and 80%, as the Oracle applications is running fine (no complaints of users).
The appearance of performance problem is not fixed in time, sometimes in the morning and in the afternoon sometimes. Sometimes, even when there are a few users logged in and sometimes it is no problem of performance, even if many users are connected. If you run a statspack you see programs to eat a lot of resources, but they are oracle programs if you can not touch or tune right? So to keep users calm, they agreed to get rebooted server. Temporarily, this solves the performance problem. So we just keep it this way. My suspect is that there are many programs of concurrent background (on request) who is running who is right for which users get slow even if only a few is connected to it. I want to know what are simultaneous programs running at the time where the performance issue of gets users.
Is there a sqlplus program to list all concurrent programs running?


Thank you very much

Mrs. Mina

What actions / solutions did you resolve performance issues in EBS?

Depends on what kind of performance issues you have.

Is it upgraded the server itself for a more powerful?

Not necessarily.

For example, our users are complaining about the Oracle Apps very slow race at any time of the day. This produces 20% of the day(performance problem) and 80%, as the Oracle applications is running fine (no complaints of users).

What part of the application? What activities do you have when there are performance issues?

The appearance of performance problem is not fixed in time, sometimes in the morning and in the afternoon sometimes. Sometimes, even when there are a few users logged in and sometimes it is no problem of performance, even if many users are connected. If you run a statspack you see programs to eat a lot of resources, but they are oracle programs if you can not touch or tune right? So to keep users calm, they agreed to get rebooted server. Temporarily, this solves the performance problem. So we just keep it this way.

    It is possible, and it depends on what simultaneous programs are underway.

  • Server Linux for EBS 11i upgrade

    Hi all

    EBS 11i
    RHEL 4.6


    Our EBS 11i is running on server HP with OS 4.6 RHEL and a single node only. This server was purchased 6 years ago and lately it is show the performance degradation. We want to migrate/upgrade to a model like high-end HP and make a knot of multiples. But the latest HP model doesn't support a minimum version of RHEL 5.
    My question is, is the support for EBS cloning 11i RHEL 4.6 to RHEL 5? How can I migrate EBS 11i with this kind of scenario?


    Thank you very much

    Hello

    It is supported on the database layer node, so there should be no problem in the migration of the database.

    #log_archive_start = true

    Since it's the eve before db, it did not matter if its commented out.

    But when I switch to it, now, the question to which it can not automatically archive the online redo, it is why ALTER SYSTEM SWITCH LOGFILE wait forever

    Thank you ALL.

  • EBS 11i supported OS

    Hi all

    EBS 11i (11.5.10.2)

    9i dB (9.2.0.6)

    RHEL 5.5

    We have the performance issue on our 9i database. He can't change his memory for more than 2 GB because of its limitation of 32-bit.

    In the first place, I do not understand why Oracle has brought together this 32bits 9i DB when they know that EBS is memory intensive software?

    You have an idea why he brought together this small memory 32-bit Database 9i?

    Can I migrate this 9i 32-bit to 64-bit 9i?

    Thank you very much.

    JC

    Hello

    The application tier is supported by Linux 32-bit 3, 4 and 5 only.

    The 9iR2 database is certified on 64-bit Linux 3 and 4.

    The best thing to do is to create a virtual Linux 4 machine and move the top database.

    You can also migrate and upgrade the database to 10g or 11g.

    Kind regards

    No, it is not required that you follow all the steps described in the note... As you have not set up a portal, you can skip this step and move to another. This is the reason why "CONDITIONAL" was used in the respective step.

  • RHEL 6 for EBS 11i (11.5.10.2)

    Hi hussein.

    I posted a thread here before on our company to buy or upgrade to a newer server which is of high quality and with more processors and memory.

    We are currently running EBS 11i (11.5.10.2) on the current server, which is about 6 years old. It is the single node only and running RHEL 4.6.

    Now, due to degradation of performance, we purchase newer machines which will be a two-node configuration. The machine seller said that the os it runs on will be RHEL 6.

    My question is... RHEL 6 supported in EBS 11i? I can clone the existing PROD EBS 11i, located on RHEL 4.6 to
    the new servers target running on RHEL 6?


    Thank you very much

    Mrs. Mina

    My question is... RHEL 6 supported in EBS 11i?

    Either you need to install RHEL4 and RHEL5.

    I can clone the existing PROD EBS 11i, located on RHEL 4.6 to
    the new servers target running on RHEL 6?

    If you install RHEL5, you can use quick Clone to clone from RHEL4 to RHEL5.

    Please see the docs for a list of pre - req software. and packages on RHEL5/OEL5

  • EBS 11i ORA-1653

    Hi friends,

    EBS 11i
    Oracle DB 9.2.0.6
    RHEL 4.6

    I just encountered error in our database ora-1653 in the APPS_TS_QUEUES tablespace, and he has two data files, namely:
    SQL> select file_name, AUTOEXTENSIBLE from dba_data_files where tablespace_name='APPS_TS_QUEUES';
    
    FILE_NAME                                          AUT

    /u02/oracle/oaproddata/a_queue02.dbf               YES
    /u02/oracle/oaproddata/a_queue01.dbf               YES
    According the metalink notes, I made the order:

    ALTER database datafile '/u02/oracle/oaproddata/a_queue01.dbf' autoextend on;
    ALTER database datafile '/u02/oracle/oaproddata/a_queue02.dbf' autoextend on;

    But it does not solve the question :(

    Do you think I need to bounce that lets database users out their login forms data entry?


    I tried to do this:
    alter tablespace APPS_TS_QUEUES add datafile ' / u02/oracle/oaproddata/a_queue03.dbf' size 500M;

    and the problem was solved.


    I don't understand why "autoextend" was not working :(

    Please clear my doubts...


    Thank you very much

    Ms. K

    Hello

    How can we avoid hitting?

    Write a notice/alert to monitor errors in the database log file, so it can be mailed to you as soon as you receive an error ORA-XXXXX.

    I read that all areas of storage should be auto-exntend on. But I know that I've done. How can I check all that storage space were autoextend on successfully? Should which data dictionary tables I check?

    It is mentioned by you in your first post.

    Thank you very much

    Ms. K

    Hello

    I tried IE, but it's also corrupt :( I don't know how to solve this problem in this PC. The only browser that accesses to this
    a firefox 2.0

    You mentioned that you could not do with Firefox 2.0, right?

    How to clean and reinstall ie? I guess I need to format my PC reinstall

    Clear the cache and browser history files and check again. Don't know which version of IE you are using and the client OS you, but you can Google 'Reinstall IE' and you should get a few useful hits.

  • WRT54GS - wireless performance problem

    Dear someone

    I am currently having performance problems with my WRT54GSv1.1

    Just received my new internet connection to 30Mbit. Unfortunately, I am not able to download at that speed. If I connect via one of the linksys router's ethernet ports, I'm a happy person, but using the wireless makes me a little less happy.

    Wireless: 15Mbit/s

    Through the cable: 27Mbit/s

    Network information:

    The distance between the router and the computer laptop 3-4 meters

    Linksys WRT54GSv1.1 - Firmware Version: v4.71.4

    Network wireless - g only mode

    TV - 6 (because all the surrounding neighbor use 10-11, I noticed using Cain Abel & wireless discovered 4.9.29)

    Security: WPA2-Personal (TKIP + AES)

    All other settings are default (just reset to the factory settings).

    Laptop:

    Windows Vista Business SP1 32-bit

    Intel PRO/Wireless 3945ABG (installed the latest drivers from the website of intel, default settings)

    When you check the diagnostic of Intel tools, it tells me the link is 54 megabits and pushes meter packages of 54 megabits, while all lower speeds remain the same.

    More diagnostic information:

    Percent missed beacons: 0

    Percent transmit errors: 18

    Current Tx power: ~ 32 mW (100%)

    Supported power levels: 1.0 mW - 32.0 mW.

    Hope someone can help me here.

    Thanks in advance!

    Kind regards

    Although wireless g "connects" to 54 Mbit/s, the maximum possible wireless "data rate" (in ideal laboratory conditions) is only about 20 to 25 Mbit/s.  Unfortunately, the phrase "in ideal laboratory conditions" generally excludes home intrusion!

    The aerial transmission for wireless connections is higher than for wired connections.   Thus, most individuals find that their Wi - Fi connection works at 50% to 70% of their speed of wired (LAN).  Your wired LAN being 27 Mbps connection speed, your 15 Mbps wireless speed is within normal limits.

    You might be able to tweak a bit more speed from your wireless network by optimizing all your wireless settings.  Here are a few suggestions:

    I guess you want actually to WPA2 encryption.  If so, set to AES only.   When you set the router to TKIP and AES, you actually tell the router to accept a WPA or WPA2 connection.

    Also, give your network a unique SSID. Do not use "linksys". If you use "linksys", you can try to connect the router to your neighbor. Also set 'SSID Broadcast' to 'active '. This will help your computer to find and lock on the signal from your router.

    Bad wireless connections are often caused by interference from other 2.4 GHz devices. This includes cordless phones, baby monitor wireless, microwave ovens, wireless mice and keyboards, wireless speakers and wireless network from your neighbor. In rare cases, Bluetooth devices can interfere. Even some 5 + GHz phones also use the 2.4 Ghz band. disconnect these devices and see if that solves your problem.

    In your router, try another channel. There are 11 channels in the band of 2.4 GHz channel 1, 6 or 11 generally works better. Discover your neighbors and see what channel they use. Because the channels overlap, try to stay at least + 5 or - 5 channels of your more powerful neighbors. For example, if you have a powerful neighbour on channel 9, try any channel 1 to 4.

    Also, try putting the router about 4 to 6 feet above the ground in an open area. Do not place behind your screen or other computer equipment or speakers. The antenna must be vertical.

    In addition, in the computer, go to your wireless software and go to 'Favorite networks' (sometimes called 'Profiles'). There are probably a few listed networks. Remove any network called "linksys". Also remove any network that you don't recognize or that you no longer use. If your current network is not listed, enter its information (SSID, encryption (if any) and key (if any)). Select your current network and make your network by default, then set it to auto login. You may need to go to 'settings' to do this, or you may need to right click on your network and select 'Properties' or 'settings '.

    If you continue to have problems, try the following:

    For wireless g routers, try setting the "baud rate" at 54 Mbps.

    If you still have problems, download and install the latest firmware for your router. After an update of the firmware, you must reset the default router, and then configure the router again from scratch. If you have saved a router configuration file, DO NOT use it.

    I hope this helps.
