Is there a limit in the number of custom columns that can be created?

Hi Experts,

Is there a limit in the number of custom columns that we can create in the informatica mappings that get out us of the box? What is the best practice for Oracle? Please let me know.

Thank you
Kris

For performance purposes, it is recommended that you do not enter a columns more than 254 to dimension to the fact table.

  • Is there a limit on the number of hot spots, that we can include on a screen?

    Is there a limit on the number of hot spots, that we can include on a screen? I'm putting in about 25, but it is defaulted to 10?

    Hot point quiz questions are indeed limited in the number, you can have on a slide.

    When it comes to normal blades, using ordinary boxes by clicking, you could easily have 25 or more, but then your score will be much more complex and it will not be a true quiz question.  Each separate click box can be set up to score separately.

  • Maximum limit for the number of periods loops that can be run at the same time?

    I am developing a simulator that requires many pieces of code to execute in parallel.  As a result, we were in loops just for this purpose.  I didn't count but there are close to 100 call loops that eventually run at a given time.

    A week ago, I've reached a point where the Simulator was working fine but when I added a more timed loop, it would break LabVIEW.  When I say LabVIEW crashed, I want to say there is no warnings that popped up, and LabVIEW just stopped completely.  Worse still, LabVIEW didn't offer even to recover the work when I start it back up again.  However, removing an additional timed loop allows everyone to work normally again.

    I'm under LabVIEW 2009 Version 9.0f3 (32 bit).  I have observed this behavior even on two different systems, one that is 3.2 GHz Xeon Quad-core with 2.0 GB of RAM, running Windows XP SP3 (32 bit) and the other is a 3.0 GHz AMD Athlon 64 Dual Core with 4.0 GB of RAM, running Windows 7 Professional (64 bit).

    Because the two systems are quite different, and LabVIEW appears to hang at the same point, I wonder if someone has already noticed such behavior.  I searched online and can't seem to find any reference to such a limit on call loops.

    One last thing.  I made an attempt to replace all the loops timed with while loops, but this seems to lead to some kind of hunger because the Simulator becomes suddenly jerky, without seeming to consume all resources more than when the call loops were in place.  So, which doesn't seem to be an option.

    I think that you are limited to 128 Timed loops in a system. Could not find anything by specifying that online, I am sure that I heard him. Also, the Sources Software-Triggered clock Timing loops can only be counted between 0-127.

    However, it certainly sounds like a bug that LabVIEW would crash during the approach of this limit rather than up a significant error.

    You can do some things to help avoid the unstable behaviour of the normal use of many parallels while loops. Place one or more loops in subVIs and then distribute these subVIs enforcement systems . This will give you your application with multiple threads of execution, which will reduce the ground being. If you don't do this, your curls probably all run System Standard of performance, which, by default, cannot have 8 wires at his disposal to share between all the loops.

  • Is there a limit on the Collections of content how you can have a site?

    I'm working on a site with a bunch of blocks of text synched. There are 20 specimens in my content panel. Everything has been working great.

    I added Collection 21 last night and all of a sudden the site does not appear... just a white screen. I looked at the source code in my browser, and there was just a line with a message about exceeding a maximum limit of 20 JSON.

    I deleted the new content Collection (21), and the site appears.

  • Is there a limit on the number of times you can use the recovery CD

    I have a desktop a6242n and the failed hard drive, I installed a new and inserted the recovery CD and it comes up with the message that this is not the correct CD for this computer. I made them when I first got the computer and used without problem. Is there a limit on the number of times I can use the recovery CD? If I buy a new game that will work?

    Hello

    There is no limit to how many times you can perform a recovery from the discs. The issue is likely because the hard drive does not have DMI information loaded on it. You will perhaps call HP and order a set of recovery disks and ask them to guide you through access to tools on the recovery disk to reload this information on the disc, assuming they are available.

    Good luck!

  • Is there a limit on the number of target makes f: AJAX?

    JSF2.1
    2.1.7 - jbossorg-1 (20120227-1401) of the Mojarra

    Is there a limit on the number of items to display on an ajax call? It seems that only the first three items in the list delimited by spaces of the IDS are returned. Nothing after the 3rd id is ignored.

    For example, the following text:
    <h:commandButton id="search" value="Search" action="#{memberDTO.retrieveMemberDetails()}">
        <f:ajax execute="f_planCode f_mbrId" render="memberName f_mbrRefId allMemberDetails notesPanel"/>
    </h:commandButton>
    ... will make properly components with the ID of 'MemberName', 'f_mbrRefId' and 'allMemberDetails '. The component with the id of "notesPanel" is NOT rendered. If I pass the 3rd and 4th ID like below:
    <h:commandButton id="search" value="Search" action="#{memberDTO.retrieveMemberDetails()}">
        <f:ajax execute="f_planCode f_mbrId" render="memberName f_mbrRefId notesPanel allMemberDetails"/>
    </h:commandButton>
    .. correctly renders the components with ID of 'MemberName', 'f_mbrRefId' and 'notesPanel '. The component with the id of "allMemberDetails" is NOT rendered.

    (1) is supposed to be the case?
    (2) if not, is this a bug?

    You don't know what just assume you that. All you know is that you don't get the result you expect, it's a completely different question that new rendering does not really. If what you say is true, I expect the notesPanel also not again.

    Different survey: why is the possibilities of Control Panel, but you're not getting the results expect you? Sure you'll find something when you do a search in this perspective.

  • apex_application.g_fxx - is there a limit to the number of lines of treatment?

    Hello

    is there a limit to the number of lines, I'm processing in a relationship with apex_application.g_fxx?

    I have a report with 7000 lines. My pk_row is apex_item.display_and_save(1,pk_id).

    When I want to loop through these lines after submit and access with apex_application.g_fxx, I get the error "page not found".
    If I have just 500 lines or 1000, it works.

    Please help, it's urgent :-(

    I'm going to guess it's the parameter maxplsqlparameters for your instance of the Apex.

    I had this happens with forms tabular and master / detail where you have a large number of lines or a number high columns resulting in a product that exceeds the value of the parameter (the number of parameters is something like lines * columns more some other small hold there).

    By default, this setting is installed in 2000 (so we had some forms had slightly more than 60 rows and columns 30 - ish which would be run against this on submit.)

    We have increased this setting to 10000 and so far, so good. We have noticed no ill effects of this. We arrived at this functional entry number based on key end users on the largest number of lines they would probably see at some point in the page.

  • Is there a limit on the number of variables?

    Hello world

    I am currently in the phase final squash bugs on my year, the developer one project. Sneak peek - to:
    www.showeaver.com/testDrive/

    I experience strange things. I have a canvas where you can create the room configurations. I can choose one or more items (tables, chairs, stages, etc.) on this floor when now SHIFT. Everything works fine (well, there are a few other bugs...) But when I open a dialogue window, which is called in my user interface controller class,-which is not at all related to my other game MVC classes for my 2D view (Yes, it is a 3D view!) -object selection mechanism is completely screwed. I'm not able to correctly select items which are repeated several times. (Assume that you drop 4 chairs, the only Chair that is selected is the first...).
    Is there a limit to the size of my classes to the number of variables I can declare in a SWF file? Some of my larger files of class as 2000 + lines of code... I heard that when using #include on a frame script you better you keep lines of the file size bellows 2000 or something, but for the classes? Anyway I do not use #includes, I have a a picture, a single line of code that starts everything...

    If you have any idea, or want to share some experiences with the limits of the MX classes (which I extend a lot in this project)...
    I also welcome other feedback on this project!

    P.S. If you need to be guided in my project: to start the application, click [translation] or [English].
    Log user: demo password: demo. and then "connect".
    You open a project, and then a floor Plan. Maybe it will open read-only, like maybe more than one demo user open 'file' at once.
    Here you can drag your furniture in place on the floor.
    To open the window responsible for my headaches, you select the menu: settings > groups and then select a group to modify. After that, it's broken...

  • Is there a limit to the number of variables that can access a host on the PXI-7831R or PXI-7841R controller.

    What are the limits on the number of variables that can be transferred between the host controller and a PXI-7841R?  For example, I have several software and controls the status items that the host controller uses to communicate with the PXI-7841R.  These elements are not dependent on digital or analog i/o of the FPGA device.  Is there a limit?  Is there a specification of speed for this communication (by the number of input/output?).  Thank you.

    Any control or indicator that you create in your FPGA LV code allocates space on the Xilinx FPGA. As with all coding, FPGA, there is no way to tell a 'limit' on the space. When you add several controls and indicators, your compilation will take more time and do different things to optimize where everything is stored on your FPGA. You can see the compilation report to see how much space you have left.

    Regarding the speed of specs between the card and the host computer, which will just be specification 133.3 MB/s PCI - fresh general speed.

  • is there a limit on the number of fonts in Windows 7 Pro?

    Just curious as to the number of fonts that Windows can handle. As I recall there is a limit in xp and earlier versions of Wimdows.

    Moving to a new computer with Windows 7 Pro... and installation of facades of the old machine, but did not want to create problems with one too many fonts.

    It of probably ridiculously high as the upper limit, but don't forget your system will load each of them into memory and they will take place in HD.

    I have seen systems with 5000 + fonts.

    Its usually a good idea to limit the fonts to the ones you actually use.

  • Is there a limit on the number of pages in the application of the APEX?

    Hi - I wonder if it is either:

    (1) a maximum number of pages allowed in an APEX application
    (2) a maximum page number that can be assigned to a page.

    I don't think I'll come anywhere near either if these limits
    There are, but just thought I would check. (I'm looking at a few hundred
    pages and a greater number of scheduled about 1000 page.)

    Thank you
    Carol

    As far as I know there is a limit in the page number - 18 digits. Maximum page number you would be 999999999999999999999999999999999.

  • Is there a limit on the number of times you can upgrade an ESXi host?

    We have VMware hosts that have been updated to ESXi 4.1 5.1 using the Update Manager.  Wouldn't we be ok to update these servers ESXi 5.5 or 6.0 without having to do a fresh install and reformat?

    Thank you

    I don't know if there is a limit to how many times where you can upgrade, but the upgrade to ESXi 4.1 to 5.1 and 5.5 is supported and works (I just tested it in my lab).

    For reference, here's the relevant articles;
