Speed of transfer network for dataguard

Hi all

Database 11.2.0.4

RHEL6

I'll put up dataguard PROD at the DR site.

What is the network speed required between servers in site/two for dataguard?

Is enough 1 MB/s?

Thank you very much

JC

You may consider setting up to use a time based on check-in.  In order to keep the size of 1 G, but the archive size is just what data is there when the archive is created.  It's much smaller than I'm used to it, so apologies for that.  See the init parameter archive_lag_target.  There are, of course, to many ways to set up DG.

ALS is a document that defines (among other things) the speed at which you can recover.  15 or 20 minutes is often suggested for when companies are unable to arrive at a precise definition.   So every 15 minutes, the db spits out a newspaper, DG move more and the applied.  Some deliberately put places in a lag time too much, then you can "pull the plug" If you know someone has screwed up bigtime, without having to make a recovery.  You also must define exactly how you will apply newspapers (there are a number of options, make sure that you understand the concepts) and expectations for the digital switchover and how to deal with the app and substitution.

  • How to speed up my signal for Auntie plu photon strength?

    Original title: problem with Auntie photon more net connection

    How to speed up my signal for Auntie plu photon strength? My net is too slow & very dull.

    Hi shilpadarbar,

    Thank you for writing to Microsoft Communities. From your problem description, I understand that the internet connection is slow. Before you start the troubleshooting steps, I need the required information:

    ·         You get the error message?

    ·         Did you do changes on the computer before the show?

    Follow these methods to the problem of slow internet connectivity.

    Method 1: Follow these steps:

    Step 1: Start the computer in safe mode with network and check if the problem persists.

    Step 2: If the problem does not persist in safe mode with networking, perform a clean boot to see if there is a software conflict as the clean boot helps eliminate software conflicts.

    Note: After completing the steps in the clean boot troubleshooting, follow the section How to configure Windows to use a Normal startup state from the link to start the computer to a Normal startupmode.

    After the clean boot used to resolve the problem, you can follow these steps to configure Windows XP to start normally.

    (a) click Start, run.

    (b) type msconfigand click OK.

    (c) the System Configuration Utility dialog box appears.

    (d) click the general tab, click Normal startup - load all services and device drivers and then click OK.

    (e) when you are prompted, click restart to restart the computer.

    Method 2: Temporarily disable the security software.

    Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you do not disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network during the time that your antivirus software is disabled, your computer is vulnerable to attacks.

    Method 3: Follow the steps in the article.

  • How to use transfer windows for xp to xp. When I plug usb computers are delivered to the top with the same screen and when I try to use the transfer to the new computer, it just said information gathering and sits for hours

    How to use transfer windows for xp to xp.  When I plug usb computers are delivered to the top with the same screen and when I try to use the transfer to the new computer, it just said information gathering and sits for hours

    Hello, welcome.

    The process is automatic and the maximum transfer rate should be about 20 GB/HR. If the process crashes during that long of a time, it's probably because of something internal rather something you're doing wrong.
    For reference purposes, I included this link. It goes into the details of the migration from XP to Vista (and the basic steps you follow). The instructions are for migrating to Vista via the network, but you can easily follow the steps and choose a different option for your specific installation.
    For both machines, I recommend you to prepare for the transfer using the following procedure:
    1. click on START > run
    2 type "msconfig" (without the quotes) and press enter
    3. go to the "Startup" tab and uncheck all the entries displayed
    4. click on 'Apply' at the bottom right
    DO NOT RESTART YOUR COMPUTER AGAIN
    5. click on START > run
    6. Type "cmd" (without the quotes). Right-click on the result at the top of the menu START and select 'run as administrator '.
    7. type chkdsk /r and press enter
    8 allow the system to attempt disassembly of the volume
    9. allow the system to plan restarting
    10. restart your computer
    11 let checkdisk analyze the file system on your hard drive
    12. Once completed, perform the same steps on the other machine
    13. Once completed, repeat the transfer

    Let us know what happens
    Thank you!

  • Bandwidth of the network for the redo log switches

    Hi all

    I'm using Oracle 11 g R2, I want to clarify the necessary bandwidth of my primary site to the secondary site (using Oracle Data guard)

    My database is an Oracle RAC 2 nodes each node has a log size to 2 GB again. listen to this file in operation every 5 minutes. It means that I'm spending a 2 GB redo log file every 5 minutes from each node. This means that 4 GB in total every 5 minutes.

    I'm planing to set up Oracle Dataguard in maximum performance mode. Is that mean I need a link between the primary and secondary site that is able to transfer files of 2 GB + 2 GB every 5 minutes?

    I do the calculation below and need your advice:

    4 GB / (5x60s) = 13981 KByte/s

    This means that I need to link to 13981x8bites/s = 111, 848Kbit/s?

    Is the above correct? your advice please

    Kind regards

  • Network for NFS

    Hello

    I have infrastructure as follows;

    2 welcome each containing 6 1Gig speed NIC each.

    A NAS storage with 4 NIC

    Two L2 Switches (managed HP).

    Planning to run it by the best recommendations and requirements, so that there should not be a SPOF any level.

    So keeping this in mind, we have designed to use ports on each server as follows:

    2 for the NFS storage, 2 for Production management and 2 others for vMotion on each server.

    A cable from each port configured for respective roles goes uplink switch1 and switch2, so if a switch goes down we still have the other switch support.

    Separated VLAN is configured by the switch to different types of traffic.

    My question as below;

    Should I team two ports on each vSS.If so that what should be the parameters for NETWORK adapters for the production, storage, and vMotion network grouping (keeping in mind cables going to switch uplink separated).

    Should I keep adapter in active-standby or active-active mode.

    I didn't think any specific settings to link pass that one cable by a single port is to go there and I don't have the choice of the channel of the ether or LACP.

    In addition, vmware license is essential and having therefore no possibility to use dynamic switches.

    Consider using 5.5.0.

    Also do you propose to use frames as well in the present.

    Kind regards

    Hello

    I suggest always you put management and vMotion on the same set of natachasery management and workloads. It makes no difference where they are subnet a perspective.  I also suggest to read the following:

    Who should you get.

    natachasery have no IP address in a vSphere environment, they act as a link between a physical and virtual switch. According to the way which you the trunk your VLAN Trunk ends pSwitch (external switch tagging) or the virtual switch (switch virtual tagging). Most people master their VLAN to the virtual switch.

    You want something like the following:

    pSwitch <->pNIC0 <->[ <->Portgroup vSwitch0] <->management (subnet1)

    pSwitch <->pNIC1 <->[ <->Portgroup vSwitch0] <->vMotion (subnet2)

    When switching between pNIC0 and pNIC1 management and vMotion end up on the same bear but when normally run that they remain separated. It is the recommended method. In this case you would master the VLAN to the vSwitch. I know some people who just do not use VLANs, but who use only separate subnets and it works as well.

    pSwitch <->pNIC2/pNIC3 <-> <->Portgroup vSwitch1 (s) <->of workloads (subnet1)

    If you use VLANs (except for vMotion) you're trunking to vSwitch1 (virtual switch tagging). If subnet1 is on the same vSwitch and the trunk is correct via pSwitch ports so he can talk to management on vSwitch0 effortlessly. Switches know how to route traffic to VLAN.

    pSwitch <->pNIC4/pNIC5 <->vSwitch2 <->Portgroup <->NFS (subnet3)

    Here we link pNIC4 and pNIC5 together or use them as a pair of failover for NFS on its own subnet / VLAN itself. This VLAN can end the pSwitch if you wish or terminate once again to the vSwitch.

    In this configuration you have 3 VLAN and 3 subnets (subnets use by VLAN are also recommended)... for example:

    VLAN100-> subnet1-> workload management

    VLAN200->-> vMOtion subnet2

    VLAN300->-> NFS subnet3

    Let the pSwitches any 'movement' of traffic for each VLAN. You need only a routing device if you want TO cross borders VLAN and there is absolutely no need to do it in this configuration.

  • AMD A6 Series: How to speed up my laptop for games

    Product number: How can J5t41UA #ABA I speed up my laptop without losing too much money?

    Andres2

    To provide a little explanation, there is really little of anything you can do with a laptop.

    To speed up your desktop for games, you could consider all the following:

    (1) upgrade the current processor to a more powerful and faster that remains compatible with the motherboard

    2) install faster memory - if it is available and if the motherboard will handle it.  If the faster memory is not available, then the current memory overclock (and if necessary, the CPU as well)

    (3) install more memory - if you use very little, say 1 GB

    (4) replace the integrated graphic card graphics high-end focus on the game - which will be VERY expensive!

    (5) replace the hard drive with one of the new, high-end SSD

    In a laptop, you can often add more memory, but not enough to actually help gaming performance; and also, you can replace the hard drive with an SSD.  But even in this case, comparative tests have shown that game by using an SSD does not result in the improvement of the notable performance during the game with a hard drive at high speed.

    So, basically, no, there is really nothing you can do to turn your laptop into a game machine.
