Hi all

Our Env
Database: 11.2.0.1
EBS: R12.1.3
OS: OEL 5.4
Platform: Linux 64-bit
not planned no user: 150

I have 2 DB nodes (RAC) with * 32 GB RAM * everyone, I want to increase the size of the SGA to * GB * 10 on each node. Please help me in setting the parameters kernal accordingly.

My current Kernal parameters are below.

kernel.shmall = 4294967296
FS. AIO-max-nr = 1048576
FS.file - max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
semaphores #: semmsl, semmns, semopm, semmni
kernel.SEM = 250 32000 100 128
NET. IPv4.ip_local_port_range = 9000 65500
NET. Core.rmem_default = 262144
NET. Core.rmem_max = 4194304
NET. Core.wmem_default = 262144
NET. Core.wmem_max = 1048586

How can I calculate these values according to my needs... y at - it a rule of thumb...?

  • Create parameters for the WriteData function

    Hello

    How would create parameters for the writedata function to populate the html code?

    Thank you

    You specify when you call the writedata function, so I guess it's in the function Get-Cluster.

    You can pass the object you create in the GetCluster function as a parameter.

    Try something like this

    Function GetCluster {
        & { foreach ($Datacenter in (Get-Datacenter)) {
                foreach ($Cluster in (Get-Cluster -Location $Datacenter)) {
                    $clusObj = New-Object -TypeName PSObject -Property @{
                        vCenter = $Datacenter.Uid.Split("@")[1].Split(":")[0]
                        Datacenter = $Datacenter.Name                    Cluster = $Cluster.Name                    HAEnabled = $Cluster.HAEnabled                    DrsEnabled = $Cluster.DrsEnabled                    DrsMode = $Cluster.DrsMode
                    }
                    writedata $clusObj            }
            }
        }
    }
    
    # Function will compile the data passed from the GetCluster Function into HTML table format
    Function writedata {
        param ($object)

  • Parameters for opening PDFs in Version XI

    I have an application that opens a PDF using Reader Version 7-10 to a page specific.

    In the XI Version this feature has been removed or changed and I can't find any documentation on the opening of the parameters for the most recent version.

    OpenActions makes no difference.

    I tried in the back with quotes, and it worked.

    With the Windows SDK Shellexecute command, he pulled down the double quotes off the name of the PDF file.

    I entered the double quotes as #34 (chr (34)) that failed, but when I tried ' "' (single quote, double quote, single quote) it worked."

    It gave the same result and the parameters passed by shellexecute looked exactly the same.

    Thank you for pointing me in the right direction.

  • Parameters for importing Windows Photo Gallery is completed. (They simply disappeared!)

    In the photo gallery Windows and Windows Live Photo Gallery the 'import' settings have disappeared. I can open the parameters dialog box and tab 'import' itself is still there but it is empty. There are no settings to change. I am still able to import, but I can't change where pictures import to or anything. The parameters are the same as the last time they were available before their disappearance.

    Basically: I open the Windows Photo Gallery (Live) and everything works fine except for one thing. When I click on import one file - Options-, there is nothing in the importation of the settings box tab. (There are no settings to change. They are not there.) It is empty. Why is it empty? (If there is already a forum for this question, would someone please direct me to it?)

    Can you please clarify what you mean by "trying to shoot metrics of specific servers for a specified period of time"?  You try to get Foglight today to retrieve the parameters of servers on September 27 between 13:13 and 13:56?  Most (all?) agents have had a limit of one hour for the collection of historical data from servers.

  • Intel platform dynamic and thermal environment parameters for Windows 10

    Hello world

    I recently watched my battery settings and I discovered that, on 10 of Windows, all possible settings for Intel platform dynamic and thermal setting of my XPS 13 9343 lack, so were present on Windows 8.1. I also tried to reinstall the driver but nothing has changed.

    Is this normal? Sorry, but certain parameters are in Italian, because I'm Italian :) but should still be possible to understand.

    How do I pass several entrance to search for GET_SEARCH_RESULTS parameter when you use the RDCI API?

    I have this code RDCI, but I get parse error as soon as I try out several settings. It works very well with a single parameter. Please advice

    Public Shared Sub {search (String content_dDocName)

    String queryText = "dDocName < match > '" + content_dDocName + "'";

    create the binder

    DataBinder searchResultBinder = idcClient.createBinder ();

    fill the binder with the settings

    searchResultBinder.putLocal ("IdcService", "GET_SEARCH_RESULTS");

    searchResultBinder.putLocal ("QueryText", queryText);

    searchResultBinder.putLocal ("ResultCount", "20");

    run the query

    ServiceResponse searchResponse;

    print a Boolean = false;

    for (int counter = 0; counter < 1000; counter = counter + 1) {}

    try {}

    searchResponse = idcClient.sendRequest (userContext, searchResultBinder);

    If (! print) {}

    myExecutable.logEvent ("GET_SEARCH_RESULTS successful call.");

    print = true;

    }

    } catch (IdcClientException e) {}

    myExecutable.logEvent ("GET_SEARCH_RESULTS failed");

    e.printStackTrace ();

    return;

    }

    DataBinder searchData;

    try {}

    searchData = searchResponse.getResponseAsBinder ();

    } catch (IdcClientException e) {}

    myExecutable.logEvent ("cannot get the answer.");

    e.printStackTrace ();

    return;

    }

    DataResultSet search results = searchData.getResultSet ("SearchResults");

    If (searchResults.getRows () .isEmpty ()) {}

    continue;

    }

    myExecutable.logEvent ("successfully obtained response - (s) dDocName ' following was found:" ");

    Iterator it = searchResults.getRows () .iterator ();

    While (it.hasNext ()) {}

    Date of birth of DataObject = (DataObject) it.next ();

    myExecutable.logEvent (dob.get ("dDocName"));

    }

    return;

    }

    myExecutable.logEvent ("failed to get a response at the time given.");

    }

    You can provide several search parameter to RIDC as follows:

    dataBinder.putLocal ("QueryText", 'xOriginalServiceId 'DISO' xApprover 'fmwtuser' ')

    In above query, I gave 2 search parameters.

    You can replace OR with AND & also you can replace 'contains' by 'correspondences' according to your requirement.

  • ODI 10 g for 11g repository upgrade: problem while reusing the schema

    Hello

    I've successfully upgraded repository from 10g to 11g using AU.  To account for changes in the repository of 10g, we need to drop the repository 11g existing and re-implementation to date the initial 10 g repository.

    I truncated patterns of upgrade to 11g (repo master and work) in the database and copied the contents of 10g in empty schemes.

    But while trying to update the diagrams using AU, the AU is to show that the scheme of the ODI is already updated!

    It seems that AU is looking at some papers from previous update.

    Is it possible to identify / modify the previous update connects so that I can use the same details of schema in AU and upgrade again.

    Kind regards

    Saby


    Hi Debbie,

    I think you can delete these records from the SCHEMA_VERSION_REGISTRY table.

    You will find this under SYSTEM account table in your database 11g.

    I hope this helps.

    As said by John, SQL * Plus does not implement caching the result to the client. You write an application for OIC (or another application that knows the OIC calls appropriate to make) that implements the setting cache the result of the customer.

    Your test is behaving as expected.

  • Paths multiple parameters for RDM attached to ESXi 5 guests

    We are implementing a new SAN, an EMC VNX and have been advised by soing installation provider to set multiple paths for all devices to roundrobin.  Also advised it us to change the OPS are / s by default of 1000 to 1.  So I wrote a PowerCLI script to do this and everything works great.  I run the script every day to ensure that all new devices are replaced with the recommended settings.

    Yesterday when I ran the script, our attached SQL of VM with RDM server has started having huge disk latency issues.  As soon as we have changed the OPS are / default 1000 s, disk latency issues went away.  We could not find EMC information saying that RDM devices should have their IOPS / s set at 1000 or what their Multipathing parameters should (currently runnin on turnstile without no significant problem), but we found information from other storage vendors saying that we should go with the settings best practices of Microsoft at least the multi-pathing is set to MRU.

    Anyone out there has any information or advice on what we should do.  We will of course ensure that the OPS are / s for the RDM are set to 1000, but what are the recommendations for multiple paths of the RDM.

    See you soon

    Ant

    As a general rule, Multipathing for RDM must be the same as that of storage of data VMFS, with the exception of MSCS RDMs, which are required to be set multiple access paths, by VMware

    I'm going to guess in your case that you had a few LUNS of the questions that you should study the trespass (or get Powerpath/VE for your env and never worry about it again).
