Observed only one IP for 11 GR 2 RAC SCAN, all the problems?

Hello

In one of our customers environment I've observed that they only used a single IP for RAC 11 GR 2 ANALYSIS, but wherever I know Oracle recommended to use 3 IPs to SCAN.

There will be problems with the single use IP Scan instead of three?

Please suggest.

Thank you

Mahi

A single SCAN VIP (with the SCANL) would be necessary in fact to get the job of RAC 11.2. Three are recommended for environments where the only VIP SCAN isn't able to handle the workload. So there is nothing wrong in this moment with your configuration. It seems, you use a configuration of DNS to resolve the name SCAN and your guys N/W used a single IP address only to the name of SCANNING resolution.

  • Only one Integrator for export csv to table and update the table?

    Hello
    I have a requirement where I need to create a single Integrator for export data in the CSV file into a custom oracle table and also use the same Integrator to download and update the custom table data. Is it possible to do this in a single Integrator.

    Thank you
    Kishore

    Yes you can do it.

    You must create a type of UPDATE metadata Integrator.

    First time:

    Custom table is empty.

    WEB ADI will download a blank Excel sheet. Copy the data from the CSV file and paste this Excel.Then download this file that will update the Integrator.

    A sample example is as follows:

    web_adi_pkg.main (param_1, param_2,... param_n)
    download_data;
    upload_data;

    Download data-> select query to download the data (select * from custom_table)
    Download the data-> insert into custom_table where NOT EXISTS (select 1 from custom_table where primary_key = primary_key_col_from_csv)
    update of custom_table where there are (select 1 from custom_table where primary_key = primary_key_col_from_csv)

    Please try above logic.

    I need to create a table of contents in iPages but I want only one word for the title, not the line of holes. Or, how can I change the contents of the table? Thank you!

    Yes, you can have a one word title, by assigning a paragraph style title to this one word. No, you cannot change the text in a Table of contents, but you can change paragraph style font attributes (line) and add for example, a head of points between the types of OCD paragraph and page numbers. No part of the table of contents will not provide hyperlinks in exported PDF documents.

    When you look up in the menu bar, you can see the word iPages, or simply Pages. There is no product of iPages.

  • I have 2 versions of windows vista running on my computer. One is before it crashed and it took all the RAM (Ram)

    I can't clean the discs because I can't load any programs because the memory has faded.  So I can not put a page of my computer desktop or download programs, I need to get my images that I have on the other program running.  I can't open one of these programs because I don't have the authorization even if I was always the user and administrator.  What I would do.  Can I add more memory Ram?  Can I remove the old stuff that I can't open anyway.  DLLs etc.  I downloaded vista 2pr, but it does not work.

    Hello

    Here is the information from your other question here about it:

    "I can't collect any information of my system information page."  When I connect I get redirected to a page that asks me what version of vista I want to open.  One is Microsoft vista and the other is windows vista.  The Microsoft is the only one that works. The other takes me a blank page. »

    "I have 2 versions of windows vista running on my computer. One is before it crashed and it took all the RAM (Ram).

    I suggest that you save your data and reinstall the operating system properly.

    There are several methods to reinstall Vista.

    See what methos works for you.

    There is no Windows Vista downloads available from Microsoft.

    You can contact your computer manufacturer and ask them to send you a set of recovery disks.

    They should do this for a small fee.

    To reinstall Vista using their recovery disk/s, you start from the 1st recovery disk they provide and follow the manufacturer's instructions to reinstall:

    You need to change the Boot order to make the DVD/CD drive 1st in the boot order:

    How to change the Boot order in BIOS:

    http://pcsupport.about.com/od/fixtheproblem/SS/bootorderchange.htm

    "How to replace Microsoft software or hardware, order service packs and replace product manuals.

    http://support.Microsoft.com/kb/326246

    And if you have never received a recovery disk when you bought your computer, there should be a recovery Partition on the hard drive to reinstall Vista on how you purchased your computer.

    The recovery process can be started by pressing a particular combination of the key or keys at startup. (Power on / start)

    Maybe it's F10, F11, Alt + F10, etc., depending on the manufacturer.

    Ask them to the proper key sequence.

    And if you do not score a manufacturer of recovery on your hard drive, you should be able to make your own recovery from her disks to reinstall the operating system.

    Go to programs > name of the manufacturer of your computer > then their system or recovery tools software topics for them, depending on how it is formulated.

    If you can't find any reference to it, contact the manufacturer for advice on how to make these recovery disks.

    Some manufacturers have more available Vista recovery disks.

    If this happens, you may need to try this instead:

    You can also borrow and use a Microsoft Vista DVD, which contains the files for the different editions of Vista (Home Basic, Home Premium, Business and Ultimate) must be installed. The product key on your computer / Laptop box determines what Edition is installed.

    Other manufacturers recovery DVDs are should not be used for this purpose.

    And you need to know the version of 'bit' for Vista, as 32-bit and 64-bit editions come on different DVDs

    Here's how to do a clean install of Vista using a DVD of Vista from Microsoft:

    "How to do a clean install and configure with a full Version of Vista '

    http://www.Vistax64.com/tutorials/117366-clean-install-full-version-Vista.html

    And once the operating system is installed, go to your computer manufacturer's website and get the latest drivers for your particular model or laptop computer.

    And phone Activation may be necessary when you use the above installation method.

    "How to activate Vista normally and by Activation of the phone '

  • Only one speaker (for both) to work (after checking the FAQ)

    Hello

    I have an inspiron N5110 R15 3 years now, a few days ago one of the speakers stopped working. When I do a test of stereo sound, the left speaker (the one that always works) its left AND RIGHT sample tones. so I figure this is on some kind of maybe Mono?

    -When I plug the headphones I have the sound on both sides.

    So far, I have tried

    1 reset

    2 tried update driver if the Device Manager

    3. turn on device

    4A ran the audio problems (win 7, 64 bits)

    5. looked around the frequently asked questions here

    * I do not uninstall the driver and downloaded a new because it seems strange to be the issue, after working for 3 years and all of a sudden it stops. you are the experts, so I'll gladly do if you say.

    current driver is manufactor (IDT high definition...)

    Thank you in advance.

    Another test, that you can run is ePSA Audio Quick Check. Note that not all ePSA and ePSA models do not all control by Audio fast. If you do not then just fail the color bar test as described in the FAQ. If you hear tones in the two speakers at the trials then the speaker itself is good and another part is the cause of the problem, probably the socket for headphones, since you know the audio working properly up to this day.

    If you hear only tones in one speaker and the other speaker is confirmed then failing or has a bad connection.

    The final test you can do is to perform a System Recovery. If it's a software problem then recovery will fix the problem and if it is material, then it will be no and hardware will be confirmed as the source of the problem. But no point in doing so, if only one speaker is heard in the previous test...

    I do not uninstall the driver and downloaded a new because it seems strange to be the issue, after working for 3 years and all of a sudden it stops.

    You need not to do because you tried the native driver which served the same purpose. A simple re-installation of the audio driver (no download) is that your settings will be lost - in other words, the default configuration is restored thus exclude a problem of configuration, such as defined as mono in the sound properties.

    If you want to check this, open the playback of the sound properties, right click on the speaker/headphones, select Properties, click the levels tab, click the Balance button. It does not matter how cursors are defined so that they are both the same level of the dB.

    Download a new copy of the pilot aims to eliminate corruption from the existing driver. Sometimes, they stop everything works correctly.

  • Traffic permitted only one-way for VPN-connected computers

My computers can connect to the VPN very well.  They just cannot access the internal network (192.168.250.0).  They cannot ping the inside interface of the ASA, nor any of the machines.  It seems that all traffic is blocked for them.  The strange thing is that when someone is connected to the VPN, I can ping this ASA VPN connection machine and other machines inside the LAN.  It seems that the traffic allows only one way.  I messed up with ACL with nothing doesn't.  Any suggestions please?
