Oracle tuxedo and Oracle tuxedo message queue on top of a virtual machine.

Hi buddies.
how is it going?
A quick question.
So we are going to go live  using Oracle Tuxedo 12.1.1.0 with Distinguished Bulletin Board Liaison and Oracle Tuxedo Message Queue 12.1.1.0  on top of a Virtual Machine (VMWARE) running Oracle Linux 6.2. However we want to know if there are any recommendations or mishaps in which we may face ahead by running Oracle Tuxedo on a virtual machine?
I mean, I am wondering if I have to worry about kernel parameters, virtual machine parameters or any other thing from which could mess up everything.
Another question.
Does oracle also provide virtual machines certification where Oracle tuxedo would run on top of ?

Hi Bruno,
I'm not sure what you mean with Distinguished Bulletin Board Liaison.  I'm guessing you mean a clustered or MP configuration?  And is it truly a clustered configuration or just a single machine MP configuration?
Regarding configuration, are you using Tuxedo services as well or just Tuxedo Message Queue?  The biggest issue related to OS configuration is around IPC resources.  If you do a tmloadcf -c on your UBBCONFIG file, it will help you determine the minimum IPC resources required.  In general I suggest configuring significantly more resources than the minimum to allow for future changes and for some of the parameters for heavier loads.  In particular IPC message queue parameters are heavily dependent upon load.  So make sure the maximum message size and queue size are large enough for your anticipated workload.  You can monitor them under load using the ipcs command.
We don't certify virtual machine environment but support them as long as the VM vendor assures compatibility, which obviously VMware and Oracle VM both do.

  • Select query differences between oracle 9 and oracle 8.

    Hi,
    I have a problem using the select query between oracle 7 and oracle 9i I don't have the same result :
    ex:
    With oracle7
    SQL> select 'champ1','champ2' from DUAL;
    'CHAMP 'CHAMP
    champ1 champ2
    With Oracle 9
    SQL> select 'champ1','champ2' from DUAL;
    'CHAMP1' 'CHAMP2'
    champ1 champ2
    So Can someone tell me how to solve this problem ? Is there a parameter in oracle 9 to set?
    Thanx.

    Whenever you are posting anything over internet forums like this - you should be very careful about not just posting the details which requires to solve the problem - also should be sensible about your question.
    This is not at all desired when you are posting such question. It may be because - you may not well aware of the fact.
    My suggestion is -> First Go through the basics Of SQL in general.
    Then go for any specific product like Oracle/ SQL Server/ Sybase etc.
    And, finally learn the advanced commands of that DB.
    You asked it - may be you thought the difference in output in terms of lines. But, that is not your actual output. That is the graphical display part only.
    Anyway,
    You can get the quite familier output by first type the following command ->
    set lin 310Regards.

  • Oracle Spatial and Oracle Forms

    Hi,
    Does anyone have experience with Oracle Spatial and Oracle Forms?
    I have generated a form, which is based on a view. The view uses the mdsys.sdo_relate operator. Somehow I am unable to get the form to perform (to get one record it takes over 20 minutes). While useing sql-navigator to process the same statement it seems no problem. The query that also uses the view, is then processed in 10 seconds.
    I also noticed that when text-functions like ' lower' of ' upper' are used to query the view, the query is processed within 15 seconds. If I don't use ' lower' or ' upper' it takes a long time (> 20 minutes) to process the query. Is it possible that this causes the bad performance of the form?
    On metalink I have found that forms and spatial do not cooperate because of the pl/sql version that
    forms6 uses. There is no solution presented, does anyone know of a work around?
    My configuration is:
    Oracle 8.1.7 on WIN2K @ PIII-800Mhz 256 Mb memory.
    Formsbuilder 6
    If requested I can post the queries that I have made.
    With regards,

  • Differences between Oracle BAM and Oracle BI and Question BAM  Data Objects

    Hi,
    I have two questions.
    1. Can someone tell me differences between Oracle BAM and Oracle BI?
    My understanding about Oracle BAM is, we use BAM to build Dashboards or Reports.
    We can also build DashBoards or reports using Oracle BI.
    I am not able to understand why Oracle has two tools for same purpose?
    Which tool is more powerful and user friendly(Oracle BI or Oracle BAM)?
    2. Every time we plan to develop Dashboard or report in BAM, we need to create BAM ADC Data Object to store Data (i.e first step is to get data from external database or application and second step is to store data in BAM ADC data object).
    My understanding is we have an extra step(i.e creating Data Object) in Oracle BAM to develop a report or DashBoard
    I am wrong pl correct me?

  • Architectural Difference between Oracle 8i and Oracle 9i

    hello there
    anybody can tell me precisely what is the architecture difference in Oracle 8i and Oracle 9i.
    or provide me the link where i can get it.
    waiting for reply

    What do you mean by "architectural differences"? Fundamentally, Oracle architecture hasn't changed a whole lot in a couple of decades. Certain implementations within the overall Oracle architecture will change over time, normally to support some new feature.
    Locally managed tablespaces, for example, automatic segment space management, and automatic extent allocation are pretty important new features, but they don't fundamentally change the architecture of allocating space for objects to store data.

    Yes! By all means, you can.
