Yes, its recommended configuration hangcheck timer at RAC

Configure the Hangcheck timer

The timer to check block is loaded into the Linux kernel and checks if the system crashes. It than the timer and check the timer after a certain period of time. There is a configurable threshold to hang - to ensure that, if exceeded will restart the machine. The hangcheck-timer module is not required for the operation of Oracle Clusterware (Cluster Manager), it is highly recommended by Oracle.

cat /etc/rc.local
modprobe hangcheck-timer hangcheck_tick = 1 hangcheck_margin = 10 hangcheck_reboot = 1

  • Regarding the Installation of Oracle BI Applications

    Hi all

    I was going through the documentation for the Oracle BI Applications, probably the old version.

    I. DAC has previously been installed as one of the components as well as the installation of Oracle's Applications of BI?

    Now, I have installed the Oracle BI Applications version 7.9.6.1. and the DAC is not installed with it. It is available in a package separate from the OTN site.

    Old Documentation says: "DAC installation is part of the * Oracle BI Analytics installation *", referring to what is said: what I've learned, it's there:
    1. "infrastructure oracle installation.
    2. "installation of oracle BI Applications.
    3 "Installing Informatica Powercenter.
    4 "Installation of DAC" in packaging separate.

    II. what does mean by * "installing Oracle BI Analytics?" It is part of all above mentioned installation or a separate installation.

    Kind regards
    Anthony.

    This is a separate installation

    Correct, you must install it separately

    Documentation of the olive TREE is not very good, there a lot of ambiguities like the one you quote.

    http://rnm1978.WordPress.com/2009/07/30/what-is-Obia/

  • Regarding the Installation of Oracle 11.2.0.2

    I want to install oracle in my server linux86-64 11.2.0.2 charges.
    Do I have to install all the 7 patches for this task?

    It will be very useful
    Thank you.

    Manish Subedi says:
    Hello
    As you said that centOS is not tenable, but instead when I installed 11.2.0.1, it allows the installation of oracle without any error.
    But when install us the patches of oracle11.2.0.2 on the same system, he throws the error: require 64-bit OS.
    I think the installation is possible on centOS (64-bit).
    I also recall that our server is linux86-64.

    "not supported" does not mean that the installation will always be error power off. It does not mean that the product does absolutely not. It simply means there will be no support if you are having problems. It may or may not work, but if it does not, you're on your own.

    If you have objections please let me inform.
    Thank you for your support and hope for a response more than you all.

    It is a symptom of textbooks classic does not have read and followed the original instructions to prepare the downloaded files.  You should have two files zip files.  They both must be decompressed in the same directory.  If you unzip using Windows graphic interface - in right click on the name of the file and selecting "extract all...". "the default behavior will be to create a directory, the same name as the zip file and extract in it.  Thus, file_1_of_2 pulls in directory_1_of_2 and file_2_of_2 extracted in directory_2_of_2.  You must override this stupid behavior by default and specify the directory yourself.  And specify the SAME directory for both files.

    Or just go to a command prompt, change directories to the directory where the two zip files are located and deliver "unzip " and "unzip ", and they will both be properly unpack to a directory named "database".

  • How to check the version installed oracle RAC

    Hi all

    Y at - it a command or file to the version installed oracle RAC. I saw some post to the topic to connect to sqlplus and access the v version $ but I need a command that does not require database either upward. I mean, even if the database is down, I should be able to know the version of oracle RAC.

    Thank you very much for your help in advance,

    I must admit that I never installed Oracle without the GUI, but I strongly think it is works, no matter how you installed Oracle. opatch is one of the essential tools that comprise an oracle installation, without him you wouldn't be able to fix your installation.

  • Regarding the installation of a single instance with ASM in AIX

    Hello
    I try to install a single instance with the help of ASM in AIX. I made the requirements for drives prior to installation.
    I'm running Universal Installer and I choose the option of database to create.
    During the stage of creation of the database, there is a page to choose the types of storage.
    I choose the DSO and then click Next.
    Caution is open and he tell ASM must CSS and it gives the following to run.
    reset of the/Home/App/tuba2/prod / 10 GR 2/bin/localconfig.

    I run but my CSS is not started and it gives the following.
    # localconfig reset
    Successfully accumulated necessary OCR keys.
    Creating OCR keys for the user 'root', privgrp 'system '...
    Successful operation.
    Configuration for local CSS has been initialized
    Stale demon CSS is running... kill now

    Checking the status of the new Oracle init process...
    Expected CRS demons to be in place within 600 seconds.
    Abandon: Oracle CSS stack seems to NOT be running.
    Oracle CSS service would not start as installed
    Automatic storage management (ASM) cannot be used until the Oracle CSS service is started

    How can I solve these problems. I'm new in ASM.
    Is there anyone to help?
    Is also the way I was using the single instance of the correct installation with ASM? or there is another way that is more efficient for the installation of the database with ASM?

    Technically, there is nothing wrong in what you do. Since your log message, it seems, has already CSS configured on your system and is not in a working state.
    I would recommend, reconfiguration of the CSS.

    Complete the following as root user.

    $ORACLE_HOME/bin/localconfig delete
    $ORACLE_HOME/bin/localconfig add
    CD /etc/init.d
    . /init. CSSD run &
    crsctl check crs
    And you can check the logs for more from diagnosis to the suite.

    I have a question after a problem to be able to install programs (JavaScript, Adobe Reader) on my laptop. I keep getting an error message that I need to log in as system administrator to allow these installs. What can I do?

    Hello

    What operating system you are using? Is that your system is connected to the domain? Also try to create the folder in the program files folder & Windows.

    You are facing the issue due to insufficient user rights to delete the entries of the special program in related folders & registry.

    Follow the procedure indicated by Walter.If persists, then you need to log in with the administrator account & then you must try the installation again.

    A number of Linux distributions do not install on a 8900 XPS effort. (which mostly worked well on a XPS 8500)

    All the solutions to allow mounting to dual boot with Linux?

    I came across the same problem initially: the system would just stroll early in the installation process. Editing the grub command-line to boot the kernel with the following option solved the problem he for me:

  • Regarding the installation of peoplesoft FSCM

    Hello

    I try to install the Peoplesoft FSCM module. I was able to install SQL SERVER, WEBLOGIC, TUXEDO, PEOPLETOLLS 8.52. According to the manual, now I need to install FSCM CD that I downloaded from the oracle e-delivery site. When I extracted the zip files that I received from oracel site, I don't see any files .bat or .exe files to install this apps. I'm following the correct procedure? Please let me know if I miss anything. This is my first installation.

    Thank you very much!

    you do the right way but double check the size of the CD that you downloaded from the site of delivery electronic oracle, if you download the finances of PeopleSoft Enterprise and Supply Chain Management 9.1: Feature Pack - March 2011 V24363-01, it should be 1.2 g (make sure that there is no pause pauses during download)
    After extraction of the Cd, you need two disks under V24363-01 folder and you can find the installer at FSCMV24363-01\Disk1\InstData\

    hope this will help you

  • FYI-regarding the installation of Tuxedo10gR3

    Hi Nic,
    During the installation of Tuxedo10gR3 under 2008 R2 64-bit should we indicate an oracle_home i.e. the folder in which i hv installed oracle(F:\oracle\product\11.2.0\dbhome_1) or can I use another folder in any other player? Also, I would like to know why is - this change since previous versions?

    10gR 3 Tuxedo has been greatly "revamped" compared with the previous version. It requires an Oracle home directory, but I've never used a hosting for binaries of the database software.
    You can use one another, Yes.
    You will have the same for Weblogic, where you can use the same as the smoking one.
