If you use network storage, configure ASM disks with external redundancy groups

Hi Experts,

If you use network storage, configure ASM disks with external redundancy groups. Don't use groups of Oracle ASM failure. Oracle failure groups consume cycles additional CPU and can run in unpredictable ways after suffering from a disk failure. When you use external redundancy, disk failure are transparent to the database and do consume no additional database CPU cycle, because it is discharged on storage processors.

This does not mean

  • RAID 1 + 0 for diskgroup + REDO1
  • RAID 1 + 0 for diskgroup + REDO2
  • RAID 5 for diskgroup + DATA
  • RAID 5 for diskgroup + FRA

Is this one suggested, the recommended best practices for oracle on VMWARE?


Thank you and best regards,

IVW

  • When you use network troubleshooting in Windows, get message Windows cannot communicate with primary dns server

    Original Title2: Windows 7 - Internet
     
     
    Original title: can someone help me?
    I use a PC at home with Windows 7.  Whenever the failure at home, I have problems connecting to the Internet. Whenever I try to go on Youtube or another website, I get "Internet Explorer can not display the webpage." Now, my internet and router are configured correctly, then why is what is happening? I ran Diagnostics and got the "Windows cannot communicate with primary DNS server." I tried to reset the TCP/IP settings. It did not work and I did three times! I tried to check the properties of my network when I went to diagnose the problem, he threw some stuff on the property sheets open and close before you reopen the properties. If someone could give a foolproof solution for this annoying internet problem I would really appreciate it. Thank you.

    Hello

    Welcome to the Microsoft community!

    While using the network troubleshooter utility in Windows, you get message that Windows cannot communicate with primary DNS server.

    What is the exact message that you get when you try to check the settings of network domestic?

    I suggest you to change network settings:

    Step 1: change network settings of the router

    a. connect to your router (by typing 192.168.0.1 or 192.168.1.1 in the address bar) and connect. Check your user manual or documentation if you don't know the references of logon.
    b. make sure you are in Setup-> basic configuration category.
    c. scroll down until you see "DHCP Server" - if it is disabled, select 'enable '.
    d. enable DHCP if you want, you can change the number that starts the DHCP IP assigning. (This is optional)
    e. use the DNS servers provided by your ISP. There are many DNS servers out there. It is preferable to use your ISP if possible.
    f. scroll down and click 'Save Settings'.

    Note: The procedure may slightly vary with different routers. You can see the manual or contact ISP for assistance.

    Step 2: change in the computer network settings

    a. click on start and then Control Panel.
    b. go to the networking and sharing Center and then click on change adapter settings.
    c. right-click on connection to the Local network and select Properties.
    d. Select Internet Protocol Version 6, and then click Properties.
    e. Select obtain DNS server automatically an address and press Ok.
    f. Select obtain IP address automatically.
    g. Repeat steps for Internet Protocol version 4 as well.

    I hope this helps. If the problem persists, let know us and we would be happy to help you.

  • ASM disks on external storage

    Is it possible to have discs ASM in Exadata in external storage, connected by any means (iSCSI, FCoE, IB)?

    We are thinking of X 2-2 as main database machine, but to replace all current servers, storage needs would be larger than Exadata book (lots of almost-never-accessed PDF files).

    What do you use on the no-exadata? iSCSI?

    I created devices in a loop on a NFS mount for a single instance database. Definitely would not recommend them for anything else that test, because performance is not great by any means. If I were forced to choose a non-exadata for extra storage storage platform, I would probably go with iSCSI. Haven't tried yet, however.

  • Tecra M5: How to use the FN + F2 fast locking with external keyboard keys?

    When to use a docking station and the keyboard of the UBS, the function key ("Fn + F2") on my tecra M5 as will not work. The USB keyboard has a Fn key, but when you press on with F2 nothing happens. Can I lock the screen another way?

    Usually, by default the FN keys work only on the internal keyboard.
    If you want to use the function key FN keyboard USB external, you must first activate this function FN.
    This function, you can enable in the Toshiba HWSetup located under the control panel.
    Here, you will need to select the keyboard tab and assign a function to the FN key on the external keyboard Fn key window.

  • Cannot deploy when you use the FPGA configuration file

    Hi all

    I'm new to NI Veristand. We use a controller NIPXI 8108 with a map of FPGA OR 7841R. Is the used chassis OR PXI 1042 q. VeriStand does not deploy, when we try to add the target FPGA. For adding, we used the default for NOR 7841R provided with veristand FPGA configuration file. The error is attached! Without adding the FPGA target, we are able to deploy.

    We programmed with LabVIEW FPGA card and it works.

    Please help us!

    Thank you

    SID

    Hi Sid

    This is because the FPGA card is not connected through the chassis

    Right click on the (unidentified) PXI system and identify as PXI 1042 q.

    Right-click on the PXI-1042 q system and identify the PXI-8108 controller.

    Then it will automatically fill the devices under the controller

    Now try to deploy again. It will work

  • Mail disappears when you use local storage to Inbox of several e-mail addresses

    After affecting all my email accounts and storage local folders to store mails in I went each account and the server settings, advanced and chose to send all incoming messages in the Inbox of local storage.

    When I do that, I see messages being downloaded, and then they disappear.

    I go back and put the accounts to use their own Inbox and I get the end messages.

    It's only when I want all accounts to send messages in the Inbox local storage that they disappear.

    I missed half a dozen on the e-mails and I have no idea who they are so I can't very well their demand to return them.

    For now I put this back to individual accounts, but I'd rather have the Central Inbox, if I can

    What I am doing wrong?

    Well, I worked around it. I have all the accounts to their own Inbox and 1 rule in each account - that moves all messages for each account in the Inbox of the local account that has all the individual rules to move sub folders.

    Not elegant, but it works.

  • Use/space problem of hard disk with Premiere Pro CS6 trial

    Hello

    A few days ago, I installed Premiere Pro CS6 test on my C:\ drive (about 9 GB of free space 2 or 3 GB is required for installation). After the launch of first, I changed all the preferences for "scratch disks" etc. for my drive D:\. I've been editing yesterday and I saw that my C:\ drive was completely full, only 1 MB left. Do not install / changed anything to my PC, just have been editing.

    So finally, I decided to uninstall the first completely and reinstall to D:\. It turns out that after the uninstall, I suddenly only 2, 2 GB of left of the original 9 GB before installation! So it seems that some temporary files are still somewhere (even if all my other temporary settings as of Windows Temp folder are also located at D :).

    I'm getting a bit tired now, because there is no transparacy in that first made during installation, and why, after uninstall, there are still about 5 GB on my precious space SSD

    Any help is greatly appreciated!

    EDIT: after you install on D:\ again once my available disk space increased from 2, 2 GB to 1, 3 GB on C:\. So first takes about 8 GB on a disc, I have not installed on and is not used to "scratch disks".

    Check yourC:\Users\ \AppData\Roaming\Adobe directory for unnecessary data.

  • Can I use a HP Mini 110-3190SF with external monitor of higher res?

    Totally new in the world of netbooks! Just bought a HP Mini 110 - 3190SF, thinking I could use it with my external monitor sometimes to take off the stump of my eyes... but the highest display resolution that Windows 7 allows me is 1024 px. (My external monitor is 1360 px). In addition, 1024 px is even properly displayed on the external monitor - the left side of the screen (including the Windows Start button) is off the screen.

    Of course, I tried the settings of the screen itself to have at least 1024 px is displayed correctly, but not joy. Ideally, I won't be able to change the output to 1360 px resolution, to take full advantage of the external display. Looking at this forum, it appears this is possible on older netbooks (Windows XP) but it does not seem possible when you run Windows 7. ??

    Obviously, huge disappointment if I'm limited to 1024 px (and even who does not display properly). All the solutions to one of them? My output doesn't appear to 1360 px? Or, failing that, at least to get my 1024 px displaying properly on the external monitor?

    Any help is appreciated...

    Thanks for the help. In fact, I solved the problem - not by installing the graphics driver, you suggested, but by installing a driver for the external monitor special I use (first time I've ever had to install a driver for a supposed to plug-and-play monitor!) and then play around with the settings. This allowed me to choose a higher resolution to 1024 px for the secondary display (IE, the monitor).

    If someone else gets stuck on this, I can give a step by step, but probably no one else would have taken longer than me to know what to do!

  • ASA 8.4 cleaning using Network Configuration and Service objects

    Hello

    As most of you know, firewall configurations can growth in order to be large and complex, making them difficult to understand and difficult to change.

    I have a cleaning using network firewall configuration and Service objects and groups of objects running from 8.4 who I want to. This ASA (8.4) has over 30 Web Server VM deployed behind each with the same basic configuration: one to the outside inside the IP address and port mapping (x.x.x.x:ftp to y.y.y.y:ftp, etc.) by using the following well known ports: FTP, 80, 443, 3389.

    Examples of my existing configuration:

    network of the Y.Y.Y.Y_FTP object

    Home y.y.y.66

    NAT (inside, outside) Static X.X.X.66 tcp ftp ftp service

    network of the Y.Y.Y.Y_WWW object

    Home y.y.y.66

    NAT (inside, outside) Static X.X.X.66 tcp http http service

    network of the Y.Y.Y.Y_HTTPS object

    Home y.y.y.66

    NAT (inside, outside) Static X.X.X.66 tcp 443 443 service

    network of the Y.Y.Y.Y_RDP object

    outside_in list extended access permit tcp any host y.y.y.66 eq www

    outside_in list extended access permit tcp any host y.y.y.66 eq 3389

    outside_in list extended access permit tcp any host y.y.y.66 eq 443

    The entries above for each port have to do whenever a new virtual machine is deployed behind the firewall.

    Here's my ACE project and entered the object-group service to clean up configuration.

    object-group service WWW_FTP

    Hello

    I'm afraid that the only part of the configuration you can really change and make more condenced is configurations ACL using configurations different ' object-group ' .

    Of course, you can also create a "object-group" for all servers that need the same ports open to further reduce the lines of actual configurations in the configuration of the CLI.

    However,.

    Regarding NAT configurations there is unfortunately no way to reduce the amount of required configurations if you use Static PAT (Port Forward) for servers. There is no way yet to ports in group for "nat" configurations.

    My question is, you have public IP addresses less at your disposal compared with the amount of different servers in your network behind the ASA?

    If you have a public IP address dedicated to each server in the network, then I suggest to use static NAT instead of static PAT. It's about the only way that the NAT configuration could be minimized.

  • How to condigure guest OS when you use net mode bridged when connecting by local security-enabled wireless network

    I am running VMWare workstation on a host with the guest OS Windows XP and ubuntu.

    I work in a place where we have a LAN wireless - security-enabled.

    When you use the NAT configuration - my OS comments doesnot seem to be able to run and use the DNS and the Windows network AD features.

    -I want to set up the guest operating system to connect to the network using the bridged mode.

    Unfortunately - the 'visible' for Windows XP network connection is reported as a wired lan connection. This means that I am not able to configure options for the connection wireless security.

    Is there a configuration missing that I forgot, I have to do on my wirtual machine, toolsthat host or vmware would allow this Setup program begin work?

    Plese - if anyone has som einput it would be greatly appreciated.

    Best regards

    Poul Christiansen

    Wireless configs should be set to the host OS, unless the wireless usb is attached directly to comments.

    For mode bridged you have, connect to the guest is actually nothing else that a wired connection and XP won't be able to use it as wireless (except usb of course).

    This means that your association and authentication to the AP will have on the host operating system linux tools.
