Oracle 12 c grid network requirments

I have a question regarding Oracle 12 c grid network requirments. This is the document I've read. https://docs.oracle.com/database/121/CWLIN/chklist.htm#CHDGJEJD we have two rac nodes. Only one public IP, virtual IP and IP address private for each node, more three IPs for ANALYSIS. My question is, private IP need to be on different dedicated switch? Thanks, Hanping

My question is, private IP need to be on different dedicated switch?

Have to be? N ° can be on the same switch, they must be on different subnets.

Should be on different switches? Definitely YES! You can have a lot of Cache Global transfers and other communications on the private network. Oracle recommends that the private network which... private... which means it will not be shared by the rest of the network traffic.

Many people who try to use the same network switch often live to regret their terrible cluster performance.

HTH,

Brian

  • ASM and SCAN listener running of the Oracle user not user network

    Hi all

    Greetings for the day!

    In one of my new customer environment, I see that ASM and SCAN are running oracle user not user network, although the ORACLE_HOME is on the grid software. I read somewhere that we should run ASM and SCAN from grid not Oracle. Please let me know if I'm right and if there are consequences of the performer of the Oracle user.

    The important word is expected here. It is suggested that 11.2, that the separation of roles, a non-oracle account must be used for the GI. But this is not essential, and certainly not wrong to use Oracle db and IM account as long as you do not use ASM according to security features. So nothing to worry about. You're good.

  • Need to understand the basics of Oracle RAC and grid technology, for training

    I need to understand the infrastructure Oracle RAC and grid, a manager / training perspective.

    I see links here and here , so a few questions:

    -What is the fundamental difference from the layman's point of view (for example, a Manager)?

    -What training options are available for a generic 11g DBA to learn this new technology? I've seen this course from a partner of Oracle ("" courses: Oracle 11 g: RAC and Grid Infrastructure Administration accelerated Release 2 ""), to a boat load of money, during 5 days I think. So we are looking for something a bit more reasonable (and accessible), for example, books, online, etc.

    For a very basic definition, ACR is technology that is used by the database and IM is the infrastructure that makes the CAR work. In a response to the forum, this is probably all that can be said about the two. For a very long answer, you should read the links you cited.

    # 2, the course you are looking at is called accelerated because it combines two courses in one week training-RAC (4) and GI (3). So it's a day 7 curriculum that we would do in a 5 day course and who must justify its cost. But let me say, it's a really very good. But on the other side, it can be pretty intimidating to someone who does not already know these technologies. So I suggest that you send your team to each course individually and no doubt after doing some research. They can start to read the following books

  • Oracle ADF Application Social network in the user interface integration

    Hello

    I'm new to ADF so that NSOS, I went through the tutorial of the ADF (development of RIA Web Applications with Oracle ADF) and heard a little.

    My requirement is to integrate the Social network of the Oracle ADF web application user interface. I found the link "implementation Oracle integration of social networks - 11g Release 7 (11.1.7)" "

    I find difficulty in the rest of the documentation, especially the pre-requisites.

    * I use JDeveloper version 11.1.1.7.0 and I downloaded all updates related to webcenter in my JDeveloper.

    I would ask to add a few screenshots more that explain where to find the URL of network Social Oracle JDeveloper.

    Otherwise a simple tutorial with screenshots would be a great help!

    Thank you

    MC.

    MC, the documentation you are looking at is specific to the Fusion Apps integration with Oracle Social Network developers.  If you are looking to make the ADF development credits, including work against NSO then this is probably not the starting point.  You are a developer of Fusion applications, or you are already a customer Oracle Cloud Apps with a NSO and application that you are trying to extend?  If you could give a little more background on what you're trying to achieve, we will be able to advise the right path to take.

    For starters, cropping the image would be beneficial. Just see the one screen, not the entire desktop.

    Yes... you need these packages. They are prerequisites for a reason. If you choose to ignore them, then you have a bad installation.

  • Where should you install Oracle database and grid Infrastructure in order to comply with OFA?

    I downloaded two files compressed to the Oracle database installation, and both zipped install files for the grid Infrastructure.  The book I'm following for installation is said to use a directory of the database and a directory for the grid Infrastructure, but it does not explain where they should be located in OFA.  Probably they should both close up somewhere in the same Base of Oracle (since all Oracle related on a single file system should go in the same basis, according to my understanding), but it is not clear where they need to be installed over the other.  For example, the grid Infrastructure is a separate product that gets its own Oracle Home?  Anyone can shed some light on this process?

    Also, does it matter where the zipped files are uncompressed?  For example, use one of these files after the installation process, or OFA only cares location after installation?

    Hello

    Which option is the best?

    If you have a CMS and repository in different servers, you can have a more scalable configuration. More, you can also install several WHO (on multiple servers - 1 SGD per host) as shown in this overview:

    http://download.Oracle.com/docs/CD/E11857_01/install.111/e15838/overview.htm#CJAHHFEA

    Of course, this type of architecture is more powerful and allow you to give more resources (CPU, memory) to EM Grid control. If you have hundreds of targets to monitors and dozens of users who can connect and use EM grid control, it may be useful to use this feature ( load balancing, several WHO,...):

    http://download.Oracle.com/docs/CD/E11857_01/install.111/e16847/install_addln_oms_slnt.htm#BABBGGAH

    However, if you have just a few tens of targets and a few users who may connect occasionally to the EM grid control, you can also install all {repository + WHO} on the same server.

    Anyway, in all cases, you must take into account related Harware requirements:

    http://download.Oracle.com/docs/CD/E11857_01/install.111/e15838/appdx_hardware_reqs.htm#CACJBDGF

    And also, it is important to know the Port number used by any component to communicate with each other:

    http://download.Oracle.com/docs/CD/E11857_01/install.111/e16847/firewalls.htm#i1005951

    Pavang is right.

    I opened a SR and Oracle Support they confirmed she RHEL 5.5 with RHEL kernel is supported (minimal support). but Oracle is highly recommend to deploy the nucleus of the unbreakable Company Oracle.

    Some reasons for their recommendations:
    http://public-yum.Oracle.com/
    The core Oracle Unbreakable Enterprise for Linux is the standard kernel used with Oracle products. The build
    and QA Oracle database systems and other Oracle products use the core of Oracle Unbreakable company
    for Linux exclusively. The core Oracle Unbreakable Enterprise for Linux is also the kernel used in Oracle
    Exadata and Oracle Exalogic systems. Oracle Unbreakable Enterprise Kernel for Linux is used in all benchmarks
    tests on Linux in which Oracle participates, as well as in the setup of valid Oracle for x 86-64.

    Hello

    What is the specific error ORA-XXXXX you receive when it is unable to connect? This will give you the index on which parameter is incorrect. You have other machines that connect to the database even when the connection descriptor has been set using local naming resolving to a tnsnames.ora file, check that the settings in this file and validate that they are correct or contact the ADMINISTRATOR of the target database and check the host name, port and service of the target db name.
