service_name multiple effect the data protection environment.

Hello

I created an environment for the protection of data in oracle 11 g 2 (11.2.0.3) on Linux OS. Now, I wanted to have the same service_name for primary and physical database of relief?

Is this possible? It will affect my Data guard environment in the future for some reason any?

Please let me know if you need more information.

Thank you

The entire process is

1. create the service on the primary (Data Guard apply makes available the day before)

BEGIN

DBMS_SERVICE. CREATE_SERVICE ('ernie', 'ernie');

END;

2. start the service

DBMS_SERVICE. START_SERVICE ('ernie');

-You can stop it too

DBMS_SERVICE. STOP_SERVICE ('ernie');

3 define some default settings

BEGIN

DBMS_SERVICE. MODIFY_SERVICE

('ernie',

FAILOVER_METHOD => "BASIC."

FAILOVER_TYPE-ONLINE "SELECT."

FAILOVER_RETRIES-ONLINE 200

FAILOVER_DELAY-ONLINE 1);

END;

/

4. create the trigger as shown before (applied Data Guard makes available the day before)

5. check the listener

>lsnrctl status

"Ernie" service has 1 instance (s).

So original running service will always be there, but use a tnsname as I have posted before and you are ready.

There are several advantages to this configuration:

Guests can reconnect using the same connection string.

Need to communicate with customers is reduced, especially after hours.

Primary maintenance may occur with only minor interruption of service. (passage)

Name of databases may be different without impact to the customer.

So, replace "ernie" with something logical and you are ready to create. The nice thing about having the original service is that you can have another alias of snapshot of database for the short tests without having customers ask why the net80 is the same as the production. It's just another alias.

    (1) when the database is harnessed for how long take use waiting for database so immediately or a few minutes?

    (2) when the server went down how long then to connect with the server backup immediately or a few minutes?

    I'm new to the data protection environment. Kindly help me

    Hello;

    I can perform a failover or a failover with Data Guard Broker in about 20 seconds. If I don't use a broker, it takes about 3 minutes.

    Quick start failover takes less time. Time will depend on the material, etc. of configuration options.

  • I am facing some problems with the installation of data protection. Please see below for details

    We use the data protection in our project.  The research that I have done in protecting data, I realized that the FDM adds the data in protected intersections to load the file that is created by FDM via the import process. The problem is that there are actions given in HFM and I get an error that says: "error: load the file cannot contain action data according to user option." I'm pretty sure that some user option (it would be great if you have an idea where I can find this user option) prevents data already present of shares to be loaded via FDM. Have faced this kind of error before? Is there a work around on this?

    Thank you

    Rohit

    Hello

    The user option which is the origin of the problem is 'File Contains Data property'. You must make sure that this load option is enabled when you start loading in FDM process if the dataset that you present must contain data of shares.

    Kind regards

  • FileVault will affect the data stored in the Cloud services?

    If I would turn on my Mac FileVault to encrypt my drive Fusion, this effect the data stored on both cloud services? In other words: with FileVault is active, all the data and documents I am storing in iCloud Drive, Dropbox or Google Drive since my Mac is encrypted also?

    And if this is the case, I'll be able to access these encrypted data from iPhone or iPad using the service applications usual cloud?

    (Ah yes and so that I am on this: person I know use FileVault.) Is there a drawback using FileVault (except that I have to remember my keyword safely, of course).

    Thank you for helping me make my decision.

    Full encryption of disk file Vault will have no effect on your cloud services. When you connect the drive is decrypted, it means any cloud service can access the same as data you - in its decrypted form. The downloads will not be encrypted (unless the service does its own encryption also).

    See the suppliers for more details. iCloud has this info...

    Security and privacy - Apple Support Overview iCloud

    You can encrypt files before uploading to any cloud service - but which is separate from the File Vault.

    File Vault has some potential drawbacks...

    If the drive does not recover the data are more difficult because data is encrypted - make good backups & test them!

    The computer is decrypting data "on the fly" which means it's more work than a system without encryption. The difference in performance is probably not noticeable with the new Macs, unless you start using reference tools.

    Forgotten / lost the recovery key & password will make the data inaccessible.

    The advantage is obvious, your files are not accessible to anyone, unless they have the password (or accessing the device when connected). Normally the files on a Mac can be read if someone know how to access the disk, that info is available anywhere on the internet

    for example OS X Lion mountain: transfer files between two computers using target disk mode

    It really depends on if you need protect your data "at rest" (when the power is turned off). File Vault will not protect you against any malware or other bad software etc. It's because the OS is actually the same when using - once that data is decrypted it is accessible, it's why File Vault like allows you to lock the screen with a screen saver password.

    See the File Vault information if you do not already done...

  • Windows 7 hangs after reboot (after "Sensor HP Mobile Data Protection" updated)

    My Windows 7 Home Premium hangs (blue screen) to the 'Starting Windows' screen after reboot. And the reason for the rebate to zero (and crash) is updated to Windows "HP Mobile Data Protection Sensor" . I did hidden, but now I need to install drivers for my webcam and every time that I turn on "automatic driver installation" update of windows server, it installs not only the WebCam drivers, but also this «HP Mobile Data Protection Sensor» update Which brings me to the crash at the next restart of Windows. The only way is to return to the system restore point.

    I use a laptop "HP Compaq 6715 b" . I had Vista prior to this (it was preinstalled with HP all the "stuff"), but after upgrade (reinstallation) of windows 7, upgrading from windows found all the drivers (and graphics and sound and even the biometric device drivers), but is now something wrong after every update "HP Mobile Data Protection Sensor" . Why? Or at least I can make him 'banned '?

    P.S. I had and have the 32-bit version of Windows.

    ny6uctblu,
    Have you checked with HP on any problems with this software?  Here is a link for download of HP for the software.  You should also check that your BIOS is up to date.  I found some info on a wire of HP on the Data Protection sensor Mobile works is not propely.  This thread can also give you some other ideas.

  • Advanced vSphere Data Protection restore client connection fails

    Dear all,

    I have a problem with the Data Protection restore vSphere Client. Including the option advanced. If I use the option of database connection I can get to my saved VM and I can also restore a single file if I want to. If I want to use the advanced option (I don't want to install flash player on each server, thank you vmware!). Whenever I try to log in with my domain account and the account root POS I get the message "failed to connect vCenter username or incorrect password.

    I tried both with my domain account (which incidentally is a valid account, I can connect to POS with the vmware client). I know that the root account is good and the password as I can also connect to POS via the menu of the server vcenter5. I am also able to enter the configuration of POS with the root account. I've stopped and started services POS with the root account.

    I am at a loss. Someone has an idea?

    Credentials change requires a restart of the device and I saw the PW in a config file, so I think it's hardcoded.

    If you have changed, may be the cause of your problem.

  • How to make shift register init happens only once, so that the data can persist across multiple tracks of a loop?

    Here's the situation:

    We are repeatedly followed eight real-world signals and comparing them to a threshold value.  We do this via a loop For inside a While loop.  The loop For runs eight times per pass.  We have implemented a binary table 1 d and the use of the index of the loop For as the array index, by putting a Boolean result in the table using the function replace table subset.  We want to keep the data in the table to be 'sticky', in the sense that any True value is locked, so even if a fake comes later, this array element true.  However, since we initialize the array in order for the replacement to the work table, we see that whenever the loop For again, it resets the table and destroys the history.

    I have attached a simple VI to illustrate the concept, using a random number generator as a stand-in for the real world signals.  How we change this VI do and entered real lock through multiples for loop runs, indefinitely?

    In case it is not obvious, I am a relative beginner, so please keep count in your response.

    Thank you
