A technical question about Oracle11g GI - settings Clusterware: misscount

Hello

We are working on 2 - node RAC environment with below configuration

Oracle11g 11.2.0.3.0

ASM

REHL 6.4 64bits

As we know that misscount represents time in seconds that a heartbeat can be missed before entering a cluster reconfiguration to remove the node.

Oracle default values for these parameters is the following:

seconds 10g RAC 60

11g RAC 30 seconds

can configure us the misscount in 3 minutes or what is the recommended h/s or bone or the n/w configuration to avoid misscount reached the question?

We have two available switches - Switch-A Primary and secondary switch B

We use Cisco or nessus switches L2 or L3, which usually takes 3 minutes during the rocker switch / switch reboot/connector and unplug operation.

We can over come this problem with the binding Configuration? What is recommended for the binding configuration mode (with A N1 and N2 with B)?

What to do to overcome or hit the question of the achieved the best @ level CARS.

Thanks in advance

Hitgon

It is not supported by oracle workaround switch failover to the misscount parameter.

Consult the MoS note: calculation of CSS in Oracle Clusterware (Doc ID 294430.1) timeout

I have, of course, that Oracle will not be supported, you set 3 minutes away from misscount.

This will compromise the integrity of the cluster.

Suppose that you set it. If you have any other related issue e.g. CPU or i/o starvation, Oracle wait 3 min to start the node.

3 minute wait an IO operation is complete without warranty who is successfully completed is a big risk.

Do not hesitate to ask the Support of Oracle.

  • Technical questions about X 1 carbon Touch base

    Please forgive me, I'm still recovering after the shock and frustration generated by dealing with Lenovo Tech Support.

    I recently received my X 1 carbon Touch and I have tried to understand some - I think - fundamental questions.

    As you know, to win 8, Lenovo doesn't have a custom recovery solution / owner. However, there are a score of Lenovo recovery on the machine. I'm /assuming/ this, somehow, can be used through the default / built-in mechanisms of recovery Windows, but I want to know exactly how without necessarily experiencing myself with it.

    In addition, the computer seems to be equipped with a mechanism of alternative stand-by, fast recovery called Intel or something like that. It is enabled in the BIOS and apparently makes use of a hidden partition of ~ 8 GB on the SSD. However, I find no indication of this mechanism working. There are no settings that I could find in Windows. I changed the BIOS to 'Immediately' setting in order to test the functionality, but put the computer to sleep does not seem to generate behavior that is somehow different from regular sleep.

    In any case, I would like advice or information on my questions above. I understand works the thing of recovery fast in order to decide if I want to recover the partition or not. I would also like to know my options I should never need re - install the delivered factory OS without actually crossed the steps. I would also if someone could tell me the best way to get support from Lenovo.

    / * I called Lenovo technical support with these issues. The person sponsor and those to whom I then was sent to had no idea what I was talking about. They had difficulty understanding terms like partition, standby, sleep, resume, and even software/hardware and implementation. It was suggested that my computer may be Intel and Lenovo not... They seemed to really come from an age of the computer. I asked to speak with someone who would have some basics of the machine that Lenovo delivered to me. I find it reasonable. At that time, I was told to talk to a knowledgeable person, I have to pay a fee. Seriously?

    elfstone,

    To find out how to work the various Windows recovery methods, please see this Microsoft Web site:

    http://Windows.Microsoft.com/en-us/Windows-8/restore-refresh-reset-PC

    The sole purpose of the recovery partition is to work with the "All delete and reinstall Windows" function of Windows 8.  If you have specific questions about the factory recovery that you can't get items from Microsoft, let me know.

    Regarding the plan of hibernation from Intel, as you noted, it takes a partition dedicated to your SSD which cannot be used for other purposes.  The only parameter in Windows is inside the application of arrangements of Lenovo in the power section.  Lenovo calls this function "in waiting for 30 days.  The only thing you can do is it turn on or off.  Here's how works "waiting for 30 days:

    1. When you close the lid, or otherwise put the system into standby mode, the system of standby for 3 hours.

    03:02 hours, the system will wake up and check things like not attached AC, wake-on-LAN not activated, USB device not attached, etc..  If conditions permit, the system will enter wakefulness of 30 days for example deep sleep.  If the system returns in normal mode to 'sleep'.

    3. deep sleep means that the content of the memory is written on the special hibernation on the SSD partition.  It is very similar to the traditional hibernation except what happens faster using methods of BIOS instead of Windows methods.  But this isn't anywhere near as fast as normal sleep/recovery.

    4. the system out of deep sleep when the cover is opened or when you press the power button.

    You have found the BIOS settings, but in fact they are ignored when Lenovo settings (and package of dependence of the Lenovo parameters) are installed on the system.  I don't really know why this design choice has been made.

    Personally, I don't see value in 30 days standby, not enough value to want to give up my expensive SSD 8 GB.  I exclusively use sleep/recovery.  The battery will last several days.  And if I'm going to be away from the computer for a long time, then I'll just stop it.

  • Question about the composition settings and make

    I looked for an answer to my question, but had to ask at resort, sorry, it's pretty basic, but a direct response is needed I think.

    I imported a project in Premiere pro with two layers of still images with movement and applied effects. I work for a few weeks now, with variations on these pictures and had many number of exports of EI through the render queue.

    After you import the compositions of first CC my starting point; composition and other settings of composition parameters are all resolved HDTV 1080 25 but the set resolution in which I unfortunately now has, is defined as 'Half' (960 * 540)... New compositions also sets the default resolution somehow half...

    My question is about my previous exports and subsequently.  Together of the composition to "Half" resolution affect the quality of my compositions exported using the render module? So far, all my renders are 1080 p by default and no 960 * 540. These have been uprezed to 1080 of 960? ... - I have not changed any setting on the resolution in the rendering module - they all came out 1080 after.

    Thank you

  • Technical questions about the development on the BlackBerry PlayBook

    Hi, guys

    Hope this is the right place to post my thread...

    I was asked to develop an application on BB PlayBook (I'm an absolute beginner on this point, however), and now what I have to do is:

    place an image in my application, and tapping on the image, the application will open a. PDF file.

    However, I'm stuck here because I did some research on this one, looks like on BB PlayBook, the only way to open a. PDF file is to be opened with Adobe Reader (version BB). My 2 questions are:

    1. how to call the Adobe Reader to open a. PDF file in my application? I tried the "browseForOpen' from the 'File' class method, it opens a file picker in my application, and I can see the. PDF file here, however, when I select the file and click 'Open', it will not open the. File PDF... and, of course, it will not

    2. based on question 1, on BB OS tablet is it possible to open a file without showing up the "file selector"? I would like to have the opened file directly as long as I click on the image that links to the file.

    I would be grateful if you could give me a quick points up on this.

    PS: I use Adobe Flash Builder 4.5 as the dev. IDE and build up my app as a Flex app.

    See you soon!

    Try the function navigateToURL (...). In addition, the class File (openWithDefaultApplication) and QNXApplication (openFile) class contains the methods to open applications preferred, based on a file.

    Before BBX 2.0 Beta, these two methods did the same thing (it didn't). It has been reported as a bug, but I'm not sure if that has been resolved. Need to try all 3 methods to see which works for your needs.

  • Small Question about Advanced Configuration settings

    When you change an advanced value of a VM, why the new object is created

    New-Object VMware.Vim.VirtualMachineConfigSpec

    When we look at the object of $vm.extensiondata.config this object looks like for me VMware.Vim.VirtualMachineConfigInfo no "context".

    So my question... to rephrase and perhaps provide some clarification... Why is context and not ConfigInfo?

    Objects of the type of information are present when you retrieve a vSphere object, objects of type Spec are used when you configure a vSphere object.

    It's the Get-ter and Set-ter from the point of view PowerCLI cmdlets.

  • question about indexing settings

    Hello

    I was looking through the release of Essbase and here's my question about the index file I deleted a populous cube and I see everthing reset to 0 except index Cache current value that remained the same when the cube is populated.

    Any help or a response in this regard is greately appericiated.

    Thank you

    No, it should not change to zero. As I said, the key cache takes the memory when the application starts and keeps it until the application is stopped even if there are no data in the cube. HE maintains that the memory for when there no are data. I've seen of many inplementations where the client has set the cache to be really fat git thought would only use what it takes, but instead, the amout set gets consumed. So, I'm called asking how they can possibly be out of memory on their server. Moral of the story, do no bigger that it must really be or you will expect a lot of the key cache memory

  • Question about RAM CL

    Hi guys. I'm finalizing my PC build and I have a question about ram CL I can't find answers for hackers page here. http://ppbm7.com/index.php/news/planning?showall= & start = 3

    I would use these two RAM sticks for example.

    Module 240 pin DDR3-1333 transcend JetRam™ 8 GB High Performance: CL9, layer 6 circuit board

    Transcend JetRam™ High - Performance 8 GB DDR3-1600 240-Pin Module: CL11, 6 layer PCB, ultimate card stability and cross-platform compatibility

    My question is, what is the best for video editing? On the one hand we have 1333 mhz to with a CL of 9. On the other hand, we have RAM 1600 mhz faster, but at a higher CL of 11. Now, I'm not one to get caught up in the technical aspects as it may seem, but I don't understand so I can make decisions, especially when price is a factor. In this case however, they are at the same price...

    Well good for video editing, important criteria for RAM is:

    • Never, never crashes - it is very important; choose only RAM sticks (certified QVL) certified provider and do not use unmatched sticks
    • Speed; faster is better - while true also, past at the speed of the RAM, or lowering of the CASE wait cycles (latency) contribute to the speed, but the gains are very low; Faster RAM is hardly perceptible vs CPU speed more fast which is very sensitive (I played with it a lot on some versions overclock and test first with PPBM speed and speed up the processor 5% performance contributes to 5% where speed RAM about 30% can speed up about 1%)

    Google "what is the CASE for the RAM" and one week at self-teaching yourself if you want to even begin to really understand speed RAM! I know enough to know there is a lot to learn about the subject. The good news is that you don't need really to know a lot to build a reliable, excellent for running Adobe products, including the first, Photoshop and After Effects:

    • Use only RAM who has certified the seller of memory for your motherboard; do not assume that if the seller indicates a set 4x8Go of sticks that will work with your motherboard that two sets of such RAM will work with a card mother 8 locations either! (too late to discuss here, but various factors may override the controller memory in the processor itself - factors include voltage RAM, number of sticks, RAM clock, status of CASE of waiting settings speed, voltage of the cpu memory controller and maybe more)
    • Increasing the speed of the RAM always helps if slightly for first speed up to 1600 MHz (for x 79 in any case) and wins the speed of RAM which are still lighter

    Now, back to why both sets of sticks are the same cost. They most likely use the same chips of RAM, which is an important factor for what it costs to build the RAM sticks. While the Asus motherboard you buy allows full customization of many, many, many things, unless you are an extreme Overclocker and plan to spend a few weeks to fine-tune a new simple version you in the bios of motherboard and it say to use XMP settings. This indicates the motherboard, how to set the speed of the RAM and sticks of timings CASE for your particular RAM with the settings the seller intended.

    You really know a lot about what you are doing to set the timings RAM in any way other than the simple choice of XMP settings safely. And, you can easily burn your CPU if you don't know what you're doing and you choose some really bad parameters.

    Kind regards

  • Satellite A350D - 20K - Question about upgrade second HDD + Temperature

    I have a question about my laptop. I have notticed it is a second location of HARD disk on the bottom.
    Is it possible to use this to increase my storage?
    And if yes, how do I do that? I don't see all the connectors.
    What type of HARD drive to use in case it is possible to use this slot machine?

    My second question is on my laptop to be very hot after a short period of use.
    I installed speedfan to record the temperature. When I start the laptop, it already is between 45 and 50 degrees.
    He stayed there for half an hour and then it starts to get warmer. When I start to use the laptop for anything, it triggers to between 70 and 80 degrees.

    This does not seem normal to me. I tried to clean the vents with compressed air, but it has not made a difference.
    I searched on the internet how to take the laptop part for proparly cleaned TI.
    But I can't so I'm looking that destroy it.

    This could be the cause and more importantly, how can I solve this problem?

    Tom

    The second HARD drive bay contains the HARD drive connectors?
    If Yes, then you can use a SATA 2.5 HARD.
    If there are no connectors, then you will not be able to use the second HARD drive

    > I have installed speedfan to record the temperature. When I start the laptop, it already is between 45 and 50 degrees. He stayed there for half an hour and then it starts to get warmer. When I start to use the laptop for anything, it triggers to between 70 and 80 degrees.

    CPU and GPU produce a lot of heat. The heat dissipation is always created then there s nothing unusual that the temperature rose to higher level.
    You can change the settings in Win 7 power management. You can set the CPU to lower performance and can increase the activity of fan, which will help lower the temperature.

  • Question about the recovery partition

    Hello.

    I have a question about the recovery of HARD drive partition.

    If I do the operation to clear the hard disk option in the wizard it will remove * all * or it will keep my partition recovery in this way I can come back later. I want to know because I would like to put on a different OS.

    I know he said he would, but caution in the PDF, I found it says that on a normal recovery too (that he would remove each partition) and I'm a little confused about how the recovery actually worked.

    Thank you.

    Hey Buddy,

    To be honest I n don't know what you mean exactly with this option to erase.

    In General, Toshiba Recovery disk will wipe your entire HDD to restore factory settings correctly. This means that if you start from that disk and follow the instructions on the screen, everything will be removed.

    In addition, the recovery disk doesn t create a recovery partition. It is not available. Disk copy just the files on the second partition in folder HDDrecovery to start an installation of HARD drive recovery.

    The hard drive on my laptop seems to be divided into three partitions = Vista (c) / data (E :) / WinRE (d) with the WinRE (D :) is quite small but others, quite large.))

    My C drive is up to 3 that GB free with about 35 GB of free data (E :) is possible to merge these two to give me a big drive? And if so, how?

    Hello

    As the user previous already said, you can manage HARD drive partitions in disk management settings.

    If you n t want to have a data partition (e) then you can try to delete it in disk management.
    Then you can add this empty space of the HARD drive for other partitions on the HARD drive.

    But note; the empty space will be placed at the end of the HARD drive. I don't know if your C partition is placed as a second HARD drive partition, but if so, then it should be no problem to add empty space to partition C (System) of m.

    I have several questions about the recovery of Satellite L750 features available to it. Any help and answers would be useful.

    (1) when I started the laptop first, he asked me to create a recovery CD incase I need to reinstall the operating system. But he also said that he built in the recovery partition, so therefore, I have to make a recovery cd or not?

    (2) will be the recovery CD is exactly the same as the recovery on the system partition?

    (3) is the partion of CD or recovery includes all the integrated software pre-installed with the laptop?

    (4) also in the device manage management it shows watch partion recovery but it is empty, is it true?

    (5) in the second partition (drive D) system, he has a record with what looks like the recovery of files and folders. Is it safe to move/remove it?

    Hello

    I'll try to provide answers:
    1 - to ensure that everything works perfectly you don t need these discs, but if something goes wrong with the HARD drive you will not be able to do anything. When you have the recovery DVDs, you will still be able to install the recovery image and once again the factory settings. So my advice to you is: create these discs as soon as possible. Use only on DVD-R media and buy products of high quality (TDK or Verbatim).
    2 - Yes.
    3 - Yes.
    4 - No. Don t be confused with this.
    5. in a first time create restore DVD, and later you can do what you want. I put t know which files mean you but don t touch anything before that of the recovery disks to be created.

    In the past, many people have been experimenting with the structure of HARD drive and partitions and later was surprised when installing disk recovery HARD has been damaged. Don t make the same mistake.
