Question about the use of size mixed with ASM disk groups

I support a RAC 10 g 10.2.0.3 running and using ASM cluster. We currently have a group of data disks, which is 600 GB in size, consisting of 3 individual raw disk 200 GB devices. The RAC cluster runs on a server pSeries IBM using AIX 5.3

I need to add more space, but the system administrator can give me only 100 GB in the new raw device. What will be the impact, if any, the addition of this feature of smaller crude disk in the same data ASM disk group? I understand that ASM is trying to "balance" the general use of each raw device. ASM still works very well, or will he constantly try to rebalance the disk group because the a raw device is only half of the other three? Any help and advice would be greatly appreciated. Thank you!

It works, I do the same thing in a production database. What happens is, asm will distribute data on the size of the disks. 200 GB drives will get two times more data than the 100 GB drive. The downside is that it will also result in an unequal distribution of the IOPS / s: adults discs will be achieved more often.

  • A few questions about the use of data and Cliq

    I have the cliq, however I chose to not get 3G (so I bought full fare). So I have a few questions about the phone and the use of 3G / 2 G/Edge:

    1 - is possible to disable completely the 2G / 3 G/Edge? I know you can switch between them, but are anyway just tell the phone to stop using them altogether since I'm not subbed to the service?

    2. when the update takes place, I guess we'll have to reconnect motoblur and etc, but if I don't have 3 G will I have motoblur connection problems after the update? Or he keeps the latest wifi settings so that it would connect to wifi to connect. When I first got my phone it was not a problem b/c I had 3G for the first month.

    I hope that makes sense, thanks!

    To stop all the data, I would like to download an application called APNDroid. He cut them all down. When you log on to blur you have 3G or WIFI doe this without getting a timeout error. During the process of setting up your Blur account, you can press the menu button and set up your wifi to work, this will connect you to Blur and your phone will be connected to the blur. If I were you I would be rethinking to do a data plan since you are really losing out on most of your main features of phones. It's your choice, however.

    Hello

    I have replaced several hard drives on some laptops but I have never used any further papers of aluminum and I have no problem with the temperature.
    In my opinion, it is not necessary.
    The cooling modules must be able to manage the temperature of the HARD drive.

  • Question about the use of secondary indexes in application

    Hi, I'm a newbie to Berkeley DB. We use Berkeley DB for our application that has tables in the following structure.

    Key to value1 value2
    ------- --------- ----------
    1) E_ID-> E_Attr, A_ID - where A_ID is String for example. A_ID = A1; A2; A3
    -where E_ID is unique but for example A1 or A2 may be part of multiple F_VITA say E1, E3, E5 etc.


    So my question is that it is possible to create secondary indexes on individual items of Value2 (e.g., A1, A2 or A3)?


    Another question, lets say we have two tables

    Key to value1 value2
    ------- --------- ----------
    2) X_ID-> X_Attr, E_ID

    E_ID-> E_Attr, A_ID - where A_ID is String for example. A_ID = A1; A2; A3

    In this case, can create us E_ID as a secondary Index but with primary Table-> E_Attr, A_ID E_ID?

    While X_ID given, we can get the chronogram, E_ID-> E_Attr, table allocation A_ID?

    Don't know if its possible.

    Thanks for reading.

    (1) when talking about data & Index, I was referring to READ ONLY BDB with no. UPDATES where you download entire files allows for example on a weekly basis. In this case, I believe that the data will be stored directly in the tree. It will not be stored in the transaction as such logs. This hypothesis is correct?

    # Storage I is nothing other than a transaction log. Read the white paper, that I mentioned.

    (2) and about the Garbage Collection operation, I meant BDB 'Cache éviction' algorithms. Sorry I have not communicated before.

    I use an LRU algorithm. What do you need exactly to know, that you can not get the doc?

  • 2 questions about the use of first Elements 8?

    Hello

    My questions stem from the same question.

    I am importing a 1200 to 900 instituted .avi files ask PE into several pieces.

    The reason is that I have an effect where a ghostly character I appear in a grave yard behind my character of Lucy.

    I then re-import him in as a backdrop and the place of Lucy and other accessories in front of her.

    There is no option in ask for crop or something like that. It is 1200 900, it is she.

    It works fine except when I export of it PE to 1200 900 it does not fill the frame, as it did until I imported to begin with.

    That is the number 1 issue.  It is not evident in the preview window that it does not occupy the framework.

    It does seem that it once it is exported.

    I can do fill the frame by dragging the largest PE image so that it does not fill the frame when I export.

    But it won't let me bring together them and make the 3 pieces as a unit.

    This makes it very difficult to then match exactly.

    My questions are...

    Is there a way to make the EP to import the AVI file to make it exactly the size it was first.

    I don't know why he puts a black boarder around the PE image.

    Otherwise, it is a way to group resizes the clips as soon as they are in PE.

    If I could find a way to do it by the percentage, I could probably understand how he must still return their full frame.

    Thanks in advance...

    Mike

    Mike,

    Although not directly related to your exact problem, this ARTICLE will give you some information about the file as "wrappers" formats, and this ARTICLE will give you some information about the CODECS. They may help to explain why some of your options to Export of Poser do not work in the field.

    I also think that your work in 1440 x 1080, you'll have much closer in your workflow.

    Good luck

  • Question about the use of the Satellite Pro A60 fan

    Hello

    I intend to get a Satellite Pro A60 and I was wondering how much the fan turns on.

    Could someone comment if the fan turns on when the machine is totally inactive, and how he lights up when the machine is used for word processing and surfing the web?

    For example, when using normally does the fan turn on 1/10th of the time, or 1/2 time etc.?

    Thanks in advance,
    Pete.

    Hello

    Sorry I can't give you specific information about the cooling fan. A60 is known to me. It's a very nice laptop. Cooling vent is in reverse I am a pretty that there is no background noise.

    If you make the decision to buy it, look at what the capacity of the HARD drive is too high and that the DVD-ROM can burn a lot of different formats (DVD Super Multi drive).

    Have lots of fun with it.

  • Questions about the function "movie Diff file with...". »

    Hello

    I started working on a project where I'm now a piece of the old code written by an employee has since left my company.  This is a file of sequence TestStand 3.0 calling on Labview 7.0 code. The thing is, there were two of these facilities at different times and, somewhere in the Woods between stations 1 & 2, the code base diverged.  Part of it was due to not being able to get the material in double right for the PXI chassis and part was, apparently, due to the fact that the customer has used the 2 machines to test different models of the object to measure.

    So, I'm looking for copies of the code installed on both machines using the diff feature in TestStand base.  (If that makes a difference, I do this view in TestStand 3.5 since TS3.0 disappeared mysteriously some corrupt on me right now on my main development machine, and if the memories are good, you need to uninstall all the latest version of TS to reinstall an earlier version.)  A quite fun process, no doubt, but a little of your time.)

    Anyway, the first thing I noticed is that many sequence steps have different values of ID of the step Properties.Step look like this: "ID #: 2vMTp0db002mQDXArddRSA.  Play with the diff screen showed an option "Ignore the unique ID of the Step" which got rid of these.  With regard to these single-step ID: when they are generated and they remain constant on a particular machine?  Beyond simple curiosity, I wonder as an another diff is in some of the "on spending target ' or 'On Custom Condition true target' under certain properties of the step and the value down there looks suspiciously like these unique ID (that is, '" ID #randomstuff' ").  Are they all updated dynamically during execution or break something by changing these (for example if I copy a sequence of a crushing in the other version)?

    So, I have filtered the unique ID's.  The next major area of difference is that many, but not all together, VI Labview calls have a difference in the properties of the step > Flexible Labview adapter properties > ViCall > connector pane Checksum > value.  In addition, in some other cases, ViCall > error > connector number is different as well.  This indicates a different underlying VI?

    There are a few other differences, but I can interpret those.  My goal is to get a file of sequence for two machines, so the code will be easier to maintain.  I think that some of the VI with different amounts of connector pane control can be different between two facilities from one of the different hardware components required a library different driver.  This leads to a third question, what to use identical sequence files when the underlying VI may be different?  Is it just the interface must be the same?  As the connector pane has the same types of data and geometry for the presentations of the inputs and outputs?

    Thanks for any help,

    Mike

    I just got the phone with the help of NOR, so no worries on the answers.

    Short version:

    The unique ID is regenerated when a sequence is copied.

    TestStand didn't need to uninstall to reinstall an earlier version of the above.

    Connector pane Checksum involves a different underlying VI, but having the same geometry/inputs/outputs/types of connectors should allow you to have an another VI of facilities without different sequence files.

    Still awaiting support on the question of if the goto pointers updated correctly when a sequence or part of a sequence is copied.

  • Questions about the use of cards microSD w / the "rocket"

    Let's say I have a microSD card that is loaded with music, and it is already inserted in my rocket, indexed and working properly.  Now, let's say I have connect my rocket to my computer and add music more on the micro SD through the "rocket" card.  Can I do this without any problem?  The "rocket" then need to re-index the entire microSD card?

    How about if I delete music on my microSD card?

    Thank you

    The length of the time it takes to do a refresh is function of the number of entries or data that must be read, not the amount of memory used. Whether you have two 4 GB cards. One is full of videos or movies, maybe 2-3. The other card has 500 music files on it, but only 2 of the 4 GB are met. the card with music files will take much more time to update the "more complete" card with 2 or 3 movies.

    But the class rating is not really come into play in this update. It is based on the speed of writing on the map, and the most recent as the 16 GB only come to class 2. So I wouldn't get all hung up on that.

    To all intent & purpose, class 2 is just as good as a class 6 in these devices. There are many other discussions and no one has yet been able to prove or disprove an advantage of one over the other in use of 'real life' with the music or video files.

    Now maybe if it is used in a digital camera where the images are written to the card and you cannot take another picture until it's over. This could be where class differences are more apparent.

  • questions about the uses of flash cs6 and the code that it exports VS. switch to other tools

    I looked at the overviews on the new version of flash and I did experiment a bit with muse and edge of adobe. I have also heard the announcement Friday 4.1 android devices will run is no longer the flash player. my questions are:

    1 does flash cs6 fuction basically the same design-wise, but when it comes to export the file, the code a combination of html and javascript rather than in a solid swf file as it was currently publishing my work as?

    2 East edge meant to supplement flash? or he will take some of the uses of the flash so edge can publish for flash and mobile devices will remain in the area of desktop applications?

    3. If I created full-flash sites in older versions of flash, can I import in cs6 and make them exported as functional across all devices?

    I guess that, overall, just trying to get an overview here so that I can decide how to move forward and what to focus on.

    Thank you!

    1. Yes. The Toolbox for CreateJS is an additional downloadable extension for Flash CS6. He's going to post html and js files that will provide the animation rather than the swf file that you would normally publish. The success or failure of the version of javascript from your animation is the result of the work within the Toolbox. You are a bit constrained in the use of the timeline in Flash for your animations. If you are only working in Actionscript, then the output will be very disappointing.

    2 edge outputs javascript, css and html for you give an animation. The user interface allows you to design within the limits of what can make the border. You can preview and adjust and adjust your animation work you. Edge is a tool of html5. It can create some animation html5. It is not a replacement for Flash. It's something that you can use to integrate the animation in html instead of Flash.

    The problems and the benefits of each are unique. It is a good substitute to learn javascript, css and HTML 5. If you don't understand the code that is created from each of these tools, you can easily end up with huge, inflated, files which improved. I'm very biased towards really knowing what is happening. If I need to change something, I want to be able to enter the code and make a change, do not add an extra piece of code to work around what was there. I don't use any of the timeline, and so nothing of what I publish using CreateJS. Well, he's going to publish, but nothing happens because there is nothing on the timeline to translate.

    You can download a trial version of Flash CS6 and try to box at tools for yourself. Edge is still in free preview, you can get a copy to http://labs.adobe.com and try to see how it works.

    Also, if you do not use the Greensock Animation with Flash platform, take a look at this. It has recently been extended to ensure similar Javascript for most libraries. http://www.greensock.com/

  • A few questions about the use of a XML file to add text in a component defined in HTML TextArea

    I use AS2 in Flash CS3.

    I have a TextArea component in the scene that load its XML text and I was able to use the ul and li tags to create lists. However, when I try to include a nested list, he inserts just a line break between the nested list and the main list rather than he dash away. Is there a solution for this problem?

    Otherwise, how would I be able to add spaces nonbreaking in the XML so that they will be inside the TextArea element? I tried and & #160; without success. I've been searching the net for some help with this and find information about the change of the incorporation of xml file with a new entry for the non-breaking space of police and that has not worked either, which leaves me a bit confused.

    Flash does not support nested lists (as you know).  You can work around this limitation by using css and create your own styles of dash.  CSS have a property marginLeft, that you can use.

  • Question about the use and connection of external mini HDD

    I am the owner of a satellite A30 714, which has only 2 usb ports, and I just bought a mini hard drive (toshiba also), which requires the use of 2 usb ports, which means that I won't have any left port for mouse or something else.

    The hard drive has an optional port of AC, but I can't find in the manual of the energy required to buy a compatible cable, so I'm asking for suggestions... can I use a multi usb hub or it will not provide enough energy? What is the cable AC adapter that I should try to find?
    find a solution in the firewire port? (the computer has a port alternative mouse).
    Can I install an additional usb port?

    can someone help?

    Hello

    The fact is that a single USB port provides about 500 my.
    If HARD drive Manual requires the use of two ports USB together if the HARD drive needs more power than a USB port can provide.
    Of course, you can try using a USB hub, but please check if the USB hub supports an external power supply. It is important.
    I don't know where you can find the power supply for the external HARD drive. You said that it is a product of Toshiba. Well, maybe you can order the cable of the Toshiba service partner in your country.
    But first of all I would like to ask the dealer who sold you this HARD drive.

    I'm not sure the firewire port, because you need an adapter "USB to Firewrier '.
    But I can't find any.

  • Question about the use of the battery double on Portege M100

    I recently had a M100 with a pair of slim-Bay batteries optionally. I have a question regarding the loading / unloading of sequence.
    It seems that when loading main battery is charged 1 followed by the secondary battery (removable). This seems logical and fair enough.

    However when it comes to the main battery appears to discharge 1 with secondary battery not passing it is 99% of the value.
    I expect the machine to unload 1 secondary battery so that in the case of having 2 secondary batteries, you can redeem them on without any worries. Also when you then install the CD player, I also, then you max left in the internal main battery autonomy.

    Are there settings to change the way in which my machine seems to work?

    Hi Max

    I'm not a technician and cannot explain how it works exactly. All that I know is all of this is controlled by electronic power supply and the user has no influence on it, and as far as I know, there is no settings allows you to specify the energy consumption.

    I agree with your opinion, but I think that there is nothing to do.

    The fact is that if you use 2 different memory modules with different properties (of lower performance) so the laptop can run with lower performance. This means that the 256 memory module slows down you memory. The best way is to use the same modules having the same properties.

  • Question about the use of constant variables in forms

    As I am still very new to forms, please forgive my ignorance, if the answer to my question is very simple. I'm trying to understand how to use constant variables in my application Forms. For example, if I want the return code of constants for the configuration application (not, mind these are examples):

    RC_SUCCESS CONSTANT PLS_INTEGER: = 1;
    RC_FAILURE CONSTANT PLS_INTEGER: = 0;
    RC_YEAR_DATA_NOT_FOUND: = 50;

    Then in a module I created, if I wanted to check the return code against one of the constants I would do:

    DECLARE
    RC PLS_INTEGER;
    BEGIN
    GET_YEAR_DATA ('2000 ', rc);
    IF rc = RC_YEAR_DATA_NOT_FOUND THEN
    -Make an error handling
    END IF;
    END;

    I know that you can declare constants within the individual procedures or packages, but I can't find information on how to do it in the world for the application. I read on the use of global variables in forms, but only the CHAR data type and the fact that the value can be modified doesn't really fit for this purpose have I missed something? Is there a config file or something for the Web server that can be used to configure these?

    Any help would be appreciated.

    Thank you

    To declare constants create a Package specification in a pll and deifne all your vitals, something like:

    PACKAGE PK_CONSTANTS IS
      RC_SUCCESS CONSTANT PLS_INTEGER := 1;
      RC_FAILURE CONSTANT PLS_INTEGER := 0;
      RC_YEAR_DATA_NOT_FOUND := 50;
    END;
    

    Then attach this pll for all your forms-modules and use it as

    IF rc = PK_CONSTANTS.RC_YEAR_DATA_NOT_FOUND THEN
      ..
    END IF;
    

    A word on exceptions or errors: to me more clear (and in the case of exceptions even better) to throw an exception only to hide behind return-codes.
