Cisco Multicast - problem of Cluster control point

Hi all

Now I've been troubleshooting an issue where in my security team in which they are unable to form a cluster with two devices of control point. (internal interfaces E1 on both).

They told me that the cluster Protocol (CCP) uses multicast to form a cluster.

Two internal interfaces are connected to my core of the switches (FEX) which are two Nexus 5Ks, which I think has some limitations regarding multicast transmissions (Please correct me if I'm wrong)

From the online support literarure, I learned to know that disable the IGMP snooping on the switch Cisco Nexus Core is a workaround.

My query is, is there any special way from PRI? If I disable the IGMP snooping it will affect all other areas of my network?

Thanks in advance.

I prefer to use IGMP snooping as planned, i.e. with an IGMP applicant if there is no Layer 3 interfaces with PIM.

    * Note * I found the solution... Before I used the system of virtualization and Citrix (XENSERVER) there was little different. That's why I'm stuck on a few easy steps... Well, the problem was that I use 61GB HDD, 5.5 GB of memory. When I create the VM I "ve used the maximum size of HARD drive and left no space for the SWAP file. I used 58 GB, and you have to assume + memory size, this means, 58 GB + 5.5 GB...   So who is right for which I didn't have enough space. Hopefully someone will find it useful. See you soon,.

  • Redo log switch always calls the control point?

    Hello

    Is a log switch redo always calls process checkpoint?

    I have a database of test on which nothing is not running, but when I switch the redo log file, so it takes time to make the State of redo log active to INACTIVE.

    But when I change check system; the State immediately changes from ACTIVE to INACTIVE.

    Gives me a feeling that the redo log switch, it is not mandatory for the checkpoint occurs.

    Notice how we have lines (marked *) what does "beginning log switch checkpoint."

    However, note that control points are not "emergency" until we have a problem with "checkpoint is not complete", and the first control point in the bucket fill in only some time after the second control point in the dumpster.  Log switch checkpoint he still 'place' (or, at least, its necessity is noticed) - but it is not the urgent case where it used to be in early versions of Oracle.

  • In what order are anchor command left and right control point values returned by entirePath()?

    The entirePath() returns the anchor points that have two values, or it returns an array with three coordinates. I would like to know, in this case, what is the point of anchorage, control point index and values of point of order from right to left?

    The three values are leftDirection, the point of anchorage and directed. 'leftDirection' and 'directed' compete in the competition for the worst property names, because they have nothing to do with the left and right. Publishers of fonts and other programs that deal with the use of the perfectly transparent Bezier curves "in" and "out." These words make sense. Adobe of not.

    To find out what values stand for, draw a simple curve with three points, then use a script to write the values to the console of the ESTK. Open the transform Panel and check the values it that that you printed in the console.

    A major problem in all of this, is that when you select a point with the direct Selection tool, app.selection [0] does not return this point (I forget now what it returns) and get a handle on a selected point is an ugly hack.

  • Question of control point

    Hello
    IM using TimesTen Release 7.0.4.3.0

    Here's my entry sysodbc.ini
    =====================

    [DG_222221]
    Driver=/opt/TimesTen/Kodiak/lib/libtten.so
    Data store = / DG/Datastore/DG_222221
    PermSize = 200
    TempSize = 50
    DurableCommits = 0
    AutoCreate = 0
    OverWrite = 0
    LockWait = 5
    LogBuffSize = 10240
    LogFileSize = 20
    Isolation = 1
    LockLevel = 0
    Authenticate = 1
    SMPOptLevel = 1
    GroupRestrict = kodiakgroup
    Connections = 840
    DatabaseCharacterSet = TIMESTEN8
    TypeMode = 1
    CkptFrequency = 60
    CkptLogVolume = 0

    Please see that frequency of control point is 60 seconds.

    Here, the problem is when I change the timestamp of my system to another date (date in advance, say original date is Mon May 11 13:17:22 2009 IST, I change to May 25 and then come back may 11); After that this checkpoint only will be not for the data store even if the checpoint process can be seen in the output of ttStatus. Control point is not moving any further even if do a restart of the service timesten.

    Can I know what could be the reason?

    Concerning
    Pratheej

    In general, most of the software will tolerate the system clock is put forward in time (there are exceptions), and most of the software (again there are exceptions) will have problems if the clock is set backwards in time, especially by such an amount. TimesTen, like many other software components (especially databases) use internal timestamps and so forth to follow things like when the control points is produced and so on. Change the time as this will of course cause problems and is therefore not supported. Basically, don't do it!

    To obtain the control points running on that store of data again, you need to you follow these steps:

    1. the data store any export to a flat file using ttMigrate - c

    2. remove the data store (using ttDestroy).

    3 re - create and re - load the migration dump data store using ttMigrate - r.

    Hello g_david,

    Thanks for the quick response!

    To eliminate the possibility of a software problem, I have recommended to perform a backup and restore of your operating system. This can be done by following this document on the backup of files (Windows 7), and more to perform a recovery of the system HP (Windows 7). This should return your system to the factory settings.

  • Problems with parental control - clicking 'Allow' has no effect and the apps / programs that are permitted by the user are not allowed.

    Hello.

    I use Windows 7.

    User account from my son has parental control of Microsoft Watch.  It cannot open an iTunes account.  When he tries to do, a widow who opens shows the administrator permission is required.  We ask in person, I type my password.  Nothing happens.  iTunes will not open and if it clicks again, the same window again.

    Another problem is that iTunes is blocked at all.  Why is this?  In my account of parental control of Microsoft, I have the option 'ALLOW' next to iTunes.

    NOTE: this problem, namely, nothing happens when I enter my password to give permission to my son for a program or a Web site, it happens a LOT.  It occurs not only with iTunes.

    PLEASE HELP ME!

    As Shawn Keene says the problem may be due to some virus/malware. If the antivirus does not detect anything, the question may be because of the hard drive. It is also a symptom of the drive reaches its end of life. It is high time you back up all your personal/important data and install a new hard drive.

  • Control point for endpoint connect is compatible with Windows 8.1?

    Original title: CheckPoint endpoint connect

    Hello

    I'll do the upgrade of Windows 8 Pro for Windows Pro 8.1.

    By choosing the upgrade path that allows me to keep all the files, settings and applications, it shows that the only application that I have to uninstall will be Checkpoint Endpoint Connect (which currently runs under Windows 8 Pro).

    At all known installation CheckPoint EndPoint Connect on Windows Pro 8.1 and installed successfully?

    Thanks for the reply.

    I've went ahead with the installation of Windows RTM 8.1 and took the risk that Checkpoint would not be compatible.

    I was able to uninstall Checkpoint, as part of the upgrade of Windows 8.1 window and subsequently install Checkpoint endpoint connect successfully.

    Therefore, I am happy to say that for our Organization and our version of the control point, it is looking like it is fully compatible with Windows 8.1.

DBWn checks at least every three seconds to determine if he has to do. When DBWn written stamps Sales, it advances the position of the control point, causing CKPT write the position of the control point to the file control, but not for data file headers.

    Concerning
    Christian

    There are many types of control points. One that will be updated on the headers of data files would be a complete control and would be applicable to the entire base. The additional control point is induced to keep on enhanching a counter that would ensure that only certain limited stamp Sales would be recovering. That's why a moment of the additional control point, data file headers are not being updated. Control file is probably updated with a "pointer to disk" which mentions the point up to which the dirty buffers are written in files (from the buffer cache) data and where to start the recovery, if necessary. Log file switch will cause a thread control point which, for one instance, would be considered a Global checkpoint only. The additional control point would be for various other reasons such as setting a value for the parameter Fast_Start_Mttr_Target etc.
