Filesystem Suggestions for Oracle on Linux

Hello. We've been running Oracle on Solaris with Veritas Volume Manager (w/ qio) for about 4 years now and we are gearing up for going Oracle (9i) on Linux (AS). Since we are just getting started I wanted to run through setting up a preliminary test machine and Oracle install (I.E., we don't want to spend too much $ just yet).
Can anyone supply some feedback on the various filesystems that come with Redhat or that are available from the open source community (raw, ext3fs, xfs, reiserfs)? Eventually we may look at things like Veritas for Linux or OCFS, but for setting up a initial testbed, might yall recommend some pros and cons, perhaps some performance estimates of going raw, versus the various linux filesystems? Also, is there a good document available for setting up raw partitions on linux for oracle? Any and all feedback would be appreciated.

Hi,
Keep in mind, if you need to use large amount of data, with databank files bigger than 2GB, some people consider the reiserfs the better option. Pther way ext3 is a good one.
Regards,
Eduardo

    In a nutshell, you install the lowest version (10.2.0.1 or 10.2.0.2, which ever is lower for your Grid Control platform), and then apply the 10.2.0.5 patch according to the readme. That should not normally take more than a day.

    That can be found using the self-help portal: http://otn.oracle.com -> Products : Enterprise Management (left edge menu). In the 'Product Focus' area, you will notice 'Application Management' which will lead you to the appropriate data sheets and supporting information.

  • Suggestions for Oracle ADF learners

    Hi ADF experts,
    Some one suggest,For Oracle ADF learners must having java knowledge ?
    I am new to JAVA & ADF. But I want to learn Oracle ADF. Is java skills must to learn Oracle ADF.
    I am Oracle BPM11g developer.So for Oracle BPM11g,Oracle ADF is front end for user interaction.
    Guide me.

    Core Java should be enough to begin with. If you know the concepts of any OOPS programming language (C/C++), Learning Core Java should be very easy.
    ADF is nothing but Oracles version of JSF (Java Server Faces) with UI components. My Point here is, it is Java that sits at the base of ADF. Hence, I would say u Must have Java knowledge to develop a REAL useful page/application.

  • Driver issue for Oracle Enterprise Linux

    Hi All,
    I have just installed Oracle Enterprise Linux. I was not able to access network. After doing lspci -- i found that my ethernet conrtoller : Atheros Communications AR8151 Gigabit Ethernet.
    Can any one tell how to install driver for this ?

    What is your output of:
    <pre>
    lsb_release -d
    uname -r
    </pre>
    What kernel driver is in use or loaded regarding your Ethernet card when you check the output of lspci -v"?
    Note that Oracle Linux just like any other Red Hat Enterprise Linux is not designed for typical consumer grade Laptops and Desktop systems.
    Does your computer vendor provide any driver software for Enterprise Linux? You might be able to find 3rd party driver support using http://elrepo.org/tiki/tiki-index.php as a temporary yum software repository. Probably kmod-atl1 or similar.

  • Recommended sound card for Oracle Redhat Linux 64 bit?

    Dear Experts,
    I'm trying to install the latest Oracle Redhat 5.
    64 bit. On a certified Asus motherboard.
    It will be a dual boot windows/Linux machine.
    And I'm having an awful time with the sound card for my new server.
    (It will be used for learning, at home. It's important to
    have sound for some instructional videos that I will also watch.)
    Other installs, sound has installed and worked fine.
    I believe it's partially because the sound came directly off
    the motherboard in those cases.
    But with this new server, it came with a sound card, no onboard.
    The sound card works with windows. But not with Linux.
    I've been swapping three sound cards in and out, trying to get
    one to work. Each has some partial success, but none meet all
    of the requirements (below).
    What is really frustrating is that I want the sound to go
    to the green headphone jack on the front of the computer case.
    To do this, there is a cable that connects the sound card, to
    the front of the chassis.
    The existing sound card that I have, has a connector for this.
    It is an "HD audio", or an AC 97 connector. There two rows of
    five pins, with one pin blocked up, so that the connector is
    inserted in the correct manner. The cord is hard wired to the case.
    You can see some images of the pins and the cords here:

    http://www.gamespot.com/pages/forums/show_msgs.php?topic_id=27289176
    You would figure that whether the connector existed or not would be a standard
    feature that would be listed for sound cards. But it's rare to find it listed anywhere.
    When I went to the computer store, I had to open all the boxes to see if it
    was there or not!!!! Manufacturers, this is not that difficult!!
    At this point, after a couple of days of struggle, I just want to buy a
    simple sound card that works right out of the box.
    Here are the requirements:
    - gets instantly recognized by Linux (Oracle Redhat 5) 64 bit, and plays sound
    with the standard Linux drivers. I believe I have all of the drivers installed,
    because a few cards do play with them automatically. During installation, I
    installed Every package available.
    - no installation of special Linux drivers required.
    - the other big requirment is that the card have output to an HD Audio,
    or AC 97 connector, and will play music through the headphone jack.
    (Believe it or not, I have one card that works fine out the back,
    but won't work through the HD Audio. But it works fine in Windows)
    - will also work with Windows 64 bit.
    Does anyone have any good sound card recommendations that will meet all these requirements?
    Thanks a lot!

    Almost a year later... what have you been listening too? :-)
    I have to admit that I'm not an expert for "sound" under Linux. I think you may find http://www.alsa-project.org/main/index.php/Main_Page interesting. It also shows which sound cards are compatible.
    ALSA is pretty much standard under Linux and stands for Advanced Linux Sound Architecture. Together with pulse-audio it provides audio and MIDI functionality to the Linux operating system and is, by default, also included in RHEL and other descendants. You can install pulseaudio support using the EPEL repository following the instructions at http://fedoraproject.org/wiki/EPEL
    wget rpm -Uvh http://download.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm

  • Where to download openmotif for oracle enterprise linux?

    Hello,
    I am in the process of installing OEM Grid 10204 on Linux 2.6.18-128.el5 on Oracle Enterprise Linux. I am checking the packages required for installation and I need openmotif21-2.1.30-11. Where can I download openmotif21-2.1.30-11 and its dependencies from Oracle website? Can I download this package from another non-oracle website? Thank you in advance.

    If you have Oracle Enterprise Linux media CD you can mount it, find the RPMs directory and install
    rpm -Uvh openmotif21-2.1.30-9.RHEL3.6.i386.rpm
    or you can download the RPM for RHEL from internet, that should works too.

    To reinforce what was mentioned in the first response...
    There is no "urgent" in these forums and your statement that everyone must jump to your request just because you say so is rude.
    You have been a viewer of these user-to-user OTN forums for more than a year. That is far long enough to know better.
    For the future, whenever you have a critical business need for information, you will need to use your support credentials and log a SR ro Oracle Technical Support. Be prepared each time to prove to them that such a need exists.

  • Suggestions for Oracle 10g  Installation using VMware in Windows XP.

    Hi All,
    I am using Intel(R) Core (TM) 2 Duo CPU P8600 @2.4 Ghz with 1.98 GB RAM with Windows XP with 70 GB disk space. I would like to install a 2 node RAC with ASM and if possible also configure a DG for learning and testing purpose.Please advice if this will work using a VMware . Is RAC VM possible only Linux or with Windows as well ?
    I think 11g is out of scope since i don't have sufficient memory.
    I am new to VMware and have not done any installations or used it till now.
    It would be appreciated if you could help with these doubts.
    1. How much memory can be allocated to each instances?If i am installing Linux how much memory is required ?
    2. what will be the load on the CPU and will i be able to use it without any resource crunch ?
    3.Once memory is allocated to VM, can it be claimed back , is it like if i am not starting the VMware services.. i have the full 2 GB in discretion?
    4. Can 10g Standard editions be used for learning purposes?
    If the above hardware is not sufficient, please suggest a suitable configuration
    Hari
    Edited by: Hari2012 on May 27, 2012 12:24 AM

    You do not have sufficient hardware - you will likely need 6GB of RAM or more, plus 100G of disk or more and a multiprocessor machine. Each VM will need at least 2GB of RAM, and once all of the VMs/RAC are installed, the system will be pretty busy running 3 OS's (host and two guests) and two databases. If you do not start up the VMs, all of the memory is available for the host to use. 10g is no longer available for download, you will have to use 11g - yes SE edition is sufficient for learning purposes.

  • RAM for oracle on linux

    512 MB RAM is mandatory for installing oracle 9 on linux 8.
    Thanks,
    Regards,
    Akshat

    Hi,
    When we use some processes that uses a lot of Linux filesystem (not direct I/O or Automatic Storage mangement) the operating system uses the "cached" RAM memory.
    Example :- If you taking a backup of on linux using tar, since based on your Sufficient RAM size, the Linux File System is going to be used and Free Memory goes to Zero (0), when you remove the tar file the Cache Memory moves to Free Memory. During some process of work the Free memory will be reduced.
    Cached RAM is also considered as free, and will be used by OS when it needs. Oracle processes prefers use Swap Space (allocated).
    Coming to the Point " limit the size of Cached Area" is not available in Linux as per my knowledge. Never experienced.
    Try for this
    Execute "/proc/sys/vm/drop_caches" => which will move cached memory to free.
    Further I did not have much experience to comment out the problem. Let's see the comments from other friends too.

  • Infrastructure suggestion for Oracle RAC and Dataguard

    Hello,
    We are working on migration business proposal and need to suggest HA and DR infrastructure solution with Oracle 11G databases. I am thinking to suggest Oracle 11g RAC and Dataguard to meet this requirement. We also wanted to cover Dev, Test and Pre Prod along with Prod in new environment. Can someone suggest cost effective, stable and scalable infrastructure for this requirement
    Best regards,
    Venkat

    In terms of cost ? Perhaps.
    In terms of performance? NO.
    Bear in mind I'm not trying to sell anything here, but in my experience hardly anything matches the performance of Exadata. It has specific features for the DB such as de iDB protocol which enables the offloading of queries to the exadata storage servers. More unique features include: storage indexes, HCC compression, smart flash cache... It's all a matter of how much you want to spend.
    Yes, you can have all your servers on the same box if you want, just make sure it is not a single point of failure. (Have appropriate safeguards in place in case of power failure, Data center catastrophes, etc). In case of LPARs on the same box, be aware of one server over-utilizing resources which would affect the other LPARs (configurable).
    More info on Exadata: http://www.oracle.com/technetwork/server-storage/engineered-systems/exadata/dbmachine-x3-twp-1867467.pdf
    If your company has a tight budget you might also look at your options with Database appliance: http://www.oracle.com/technetwork/server-storage/engineered-systems/database-appliance/documentation/oracle-db-appliance…
    Database appliance has more flexibility in terms of licensing and it's also a complete hardware solution from oracle for Databases.

  • Suggestion for oracle developer 2.0

    could oracle developer add some new feature to monitor the oracle performance.are there any tools anybody used to monitor the oracle performance, please give me some advice,thanks.

    You can make feature requests on the SQL Developer Exchange (see the link at the top of the forum).
    SQLDeveloper already has support for explain plan, tracing and profiling which are most of what you need for development performance testing in development. There is also a plug in from 4th Elephant which does some instance monitoring.
    I would be strongly opposed to bloating SQLDeveloper with performance monitoring features. Oracle Enterprise Manager provides all the performance monitoring you could need. There are also a number of third party tools, but I don't know enough about any of them to recommend any of them.

  • Suggestion for Oracle: Distribute java using up2date

    I've been hunting high and low for the simplest possible way to both a) install and b) keep updated "sun java" on our oel-boxes. Earlier, we've been downloading and installing RPMs from java.sun.com, but that of course deals only with installation, and not updating.
    Hence, I believe this is a suggestion -- but if someone says "you can do it now", consider this the question "how":
    * Create an up2date-channel that contains the latest java-versions (jre, jdk, 32bit, 64bit)
    * Let me install it using "up2date java-1.6.0-sun-devel"
    * ...and let "update -u" keep it updated
    Doing this will help me install and enable me to keep it updated -- both of which are laudable goals, I think!
    Also, it seems that RedHat already does this, using their "Supplementary Server" channel, ref http://docs.redhat.com/docs/en-US/JBoss_Enterprise_SOA_Platform/5/html/Getting_Started_Guide/appe-install_jdk_rhel.html.

    btw - not that this helps your case right now but
    we already have virtualbox on ULN in a channel and it's up to date / current. We'll do a better job at all the others as well.
