(1) why don't we not create an odd number of voting record?
With regard to the vote of the disks are concerned, a node must be able to access exclusively more than half of the discs with the right to vote at any time. So if you want to be able to tolerate a failure of n disks to vote, you must have at least 2n + 1 configured. (n = 1 means 3 discs with voting rights). To you can configure up to 32 disks with voting rights, to the providing protection against the 15 simultaneous disk failures.
Oracle recommends that customers use drives 3 or more with right to vote in Oracle RAC 10g Release 2. Note: For best availability, 3 files of voting should be separate physical disks. It is recommended to use an odd number as 4 drives will be more highly available than 3 disks, 3 1/2 is 1.5... rounded up to 2, 4 1/2 is 2, once we lose 2 discs, our cluster fails with 4 disks with voting rights or 3 discs with right to vote.

(2) only the cluster checks actually for the counting of the votes before node eviction? If so, could you expain this process briefly?
Yes. If you lose half or more than all your discs with right to vote, then nodes get evicted from the cluster, or nodes to expel from the cluster.

(3) what is the logic behind the documentaion note which says "each node must be able to see more than half the disks with right to vote at any time"?
The answer to the first question is will also answer this question.

  • can we have more than one type of topology for a rule?

    Hello

    5.6.4 can we have more than one type of topology for a rule? How insert and separate?

    Thank you.

    Try something like this, but be very careful that you understand the implications of the scope of the rule to a very large number of objects:

    $objectsbytype(/Host|) VMWVirtualMachine | VMWESXServer | VMWCluster | VMWDatastore /) If you do not need to check each type separately

    or

    the ((hôte où name like 'a%') Union (VMWVirtualMachine where name like would be %')) If you need condition the type of each object separately, and then join the results)

    How to restore items where my images are returned in the top left corner when it is open, and they have a "mesh" around them? Something to reset elements so that the image appears in the center of the box... I can't have more than 1 image open at the same time to work on. I e I can't pass a layer on the image to the other.

    OK - I got out my trusty Photoshop Elements 10 - The Missing Manual and figured it out. What I was trying to describe, it was how to make images with 'tab' images 'floating '? This has somehow reset without my knowledge. What you need to do to get your images 'Floating' back is to click on "EDIT" in your editor - at the bottom of the drop-down list hover your cursor to "GÉNÉRAL" and click on - at the bottom of the drop-down list, click in the bottom left box 'ALLOW FLOATING DOCUMENTS IN FULL EDIT MODE' - and then click OK.

    That solved my problem!

    CMDGW_CAT:1546: ERROR: dmloadcf: above the errors found during the syntax check

    increase the value of the parameter RDOM plus 3?
    How?

    Thank you...

    Hello

    Syntax:

    Service LDOM = local_domain RDOM = dom1, dom2, dom3

    sets the remote domains of failover for this particular import. It is not intended to provide access to a service in several areas. What you want, it's basically what you were doing, i.e.,.

    Service LDOM = local_domain, RDOM = dom1, dom2
    Service LDOM = local_domain, RDOM = dom2, dom3
    Service LDOM = local_domain, RDOM = dom3, dom4
    Service LDOM = local_domain, RDOM = dom4, dom1

    It would provide balance between the 4 areas and always provide areas of failover, although assigned to the ON_STARTUP linking strategies, then the following is sufficient:

    Service LDOM = local_domain, RDOM = dom1
    Service LDOM = local_domain, RDOM = dom2
    Service LDOM = local_domain, RDOM = dom3
    Service LDOM = local_domain, RDOM = dom4

    As only active areas will be used and those inactive is ignored.

My work requires that I have strictly for work purposes only to get rid of my phone personal is not an option. Is there a way to have the disc records hard icloud of two different accounts on the same mac under the same profile?

    ICloud there than one disc for each Apple ID. You can, however, create more than an Apple ID, but that creates other issues as demanding that you trade ins iCloud to access the content of the newspaper reader.

    You can create subfolders in your drive to iCloud for work and personal use. You can also purchase a subscription to more storage if you need.

    No solution to this question. Each has its compromise.

    Could you use, say, iCloud for your personal files, but use Dropbox for those work-related?

    Hello

    Certainly, you CAN define functions with OUT parameters. It is generally not advisable to do so, however. Working with settings, for example, can be called from SQL, among other useful things.

    If you are wanting a function that returns multiple values, you would generally be

    -create a function that returns a type of object that encapsulates the values that you want to return
