Data hold does not work after changing time system

Hi guys,.

I configured Oracle Data Guard successfully between a primary database and a database physical standby.

Later, I changed the date and time in the two servers at the level of the BONE (from 14 - Sep to the 13 sept). The time is the same on both servers, but it has been changed. Then, I created a test table in the primary database, but I see not in the database of relief, well that configuration sounds good.

Could you please explain?

It is 11.2.0.1.0 - 64 bit Linux.

Here is the code:

In the primary:

SQL > select sysdate to double;

SYSDATE

---------

13-SEVEN.-15

SQL > desc hr.test

In the database backup:

SELECT SEQUENCE #, APPLIED, FIRST_TIME NEXT_TIME

Hello

You can check availability using v$ view dataguard_status.

You can make a request on a user table at the backup site if the standby instance is in recovery mode.

to check your test table, you must stop the recovery mode and start in read-only mode

Cancel log apply services:

SQL > ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;

Open the database for read-only access:

SQL > ALTER DATABASE OPEN READ-ONLY.

Then you can query your table test.

  • HARD does not work after changing the disk partitions recovery media creator

    Hello world

    After installing windoows 8.1 April major upgrade (win 8.1 presents as OEM), and have shrunk C partition to create a data partition "D", "Troubleshooting" option under advanced start menu is no longer available.

    Toshiba Recovery Media Creator does not work, too (it can not find any hard disk recovery partion).
    I got in the OEM recovery partition.
    I am also able to create a recovery using the Windows tool unit.
    You have no idea about it?

    Thank you very much!

    Hello

    Sorry to hear about all this. Unfortunately, you now have a big problem. I don't understand why you didn't create support of recovery before you started to change the factory settings, including to change the structure of the partitions of HARD drive.

    Mobile offered with factory settings a structure specific partitions and recovery recorded image is saved on the partition of drive specific and marked with invisible markers. These markers are visible for preinstalled Toshiba recovery media creator tool and when you start the tool can find points of reference and has full access to specific files.

    Unfortunately, after changing the original scores structure Toshiba tool cannot find these markers more and is not able to copy files from recovery media recovery. What you need now is the original recovery disk. Using this disk, you can install original recovery image and after doing this, you will have new factory settings.

    I know it sounds stupid now but you must order the original recovery disk and it can be done on https://backupmedia.toshiba.eu/landing.aspx

    If you have any other questions you are welcome.

  • VMWare Update Manager Server does not work after changing name of host/IP

    I have Virtual Center 2.5 update 4 and Manager Update on two separate servers.

    I had to rename and change the IP of the Server Manager to update, and now the Server Update Manager does not work.

    Here are two mistakes that I get, when you try to activate the plugin Update Manager:

    "The server took too long to respond" or "VMWare Update manager cannot accept applications because VirtualCenter.

    Server is not reachable, or it's the database is not reachable

    by train to stop'

    That's what I did to change the host name:

    -J' uninstalled virtual UpdateManager 1.0 Clients Center customer.

    -I stopped the Service VMware Update Manager on the update server

    -J' I renamed the update server changed its IP address and the host name and then rebooted the server (without starting the VMware Update Manager Service)

    -J' changed the value of the fields

    dbo. VPX_EXT_CLIENT. URL

    dbo. VPX_EXT_SERVER.UR

    -in the vCenter (on the vCenter server) database reflecting the new name of the server (the new hostnameis to pings to the vCenter server)

    -J' restarted the vCenter Server

    -J' started the Service VMware Update Manager on the update server

    -J' installed the client plugin update manager Virtual Infrastructure client

    -J' have TRIED to activate the plugin, but I got a warning about an untrusted certificate (I guess it happened also when I installed the client for the first time, and everything worked) and then I got two errors:

    sometimes "the server has taken too much time to react" and a few other times "the VMWare Update manager cannot accept applications because VirtualCenter.

    Server is not reachable, or it's the database is not reachable

    by train to stop'

    I think that there are a few other references to the host name of the Update Manager, which I have not changed, on the vCenter server or Manager Update server...

    Does anyone have an idea what do I do?

    Thank you in advance.

    I would try just reinstalling the update on existing installation manager.  Do not overwrite the database in the process so that you shouldn't really lose anything.  Not the plugin, but since the Update Manager vCenter installation media.

    Give that a try and let us know how it goes.

    After resetting my computer to factory settings, audio dolby does not work. This is the error message I get:

    I have the same problem, I have a 70-Z40 and the Dolby Digital Plus open, but does not work, you can choose the profile but is not even, I have this problem after the last windows 10 updated a few days ago.

    I hope you can help, thanks in advance

    EDIT: I solved it after a few tries, I don't know if it is the best way, but it's how I solve this problem:

    (1) Delete last windows update (after that, it did not)

    (2) delete the sound driver from Device Manager and reboot (it did not)

    (3) download the driver for my lenovo model page and install it (it did not)

    (4) any uninstall Conexant audio and Dolby of my computer and re - install again (it does not), it seems that my dolby 7.6.4.9 driver version is not correct, I need the 7.5.1.1

    (5) again to uninstall everything and restart

    -From there, he solved my problem

    (6) go on my computer (my system is in Spanish, so I don't know the correct name for the version in English, sorry) and then go to the Lenovo partition, then open drivers > Audio > Setup.exe This will install your Conexant audio driver, and then restart.

    (7) after you restart your laptor, do the same thing... Lenovo > drivers > Audio > DolbyGUI > x 64 > DolbyDigitalPlusHT.msi, and then restart your computer and it should work fine.

    Sorry for my English.

    Hello
    where did you changed them? In the BIOS or in the Toshiba HW setup?

    I suggest you go into bios after turning on your machine. You have to hit just F2 Ant then in the search for bios for setting "all default setting" or something with "bios setup defaults" to reset your bios settings.

    After that, your computer should start up again.

    Have you installed the driver appropriate for the printer?

    Adobe is a company, not a program. Do you mean Adobe Reader? If so,.
    What is unsuitable for the way it reads?

    Also, I strongly recommend to move from Adobe to the free Foxit Reader
    Drive to http://www.foxitsoftware.com/Secure_PDF_Reader/ I think there
    much better than Adobe Reader.

  • Satellite P105-S6217 - 5-in-1 SD card reader does not work after upgrading operating system

    OK, here's my situation:
    I installed my OS Satellite P105-S6217 from Vista Home premium 32 bit to Vista Ultimate 32-bit. I made sure to reinstall all my drivers. I jumped into an SD (2 gigabytes) and nothing happens.
    I checked my host adapters Manager/SD device and it says that the device is functioning properly. I noted, however, that, under the tab other devices, something seems wrong with the mass storage controller.

    I checked the status of the device and it say the drivers for this device are not installed. I swear I have install all drivers. I'm naïve about what to do next. Can someone advise me?

    Do you have the yellow marks in Device Manager?

    I searched Toshiba driver download page and there is the Toshiba memory Flash utility. In this package are the drivers for the SD card and the utility to format the SD card.
    If you install this.
    http://www.CSD.Toshiba.com-online download-online portable => Satellite-online P105-S6217

    After installation, try to format the SD card with the utilities. After that, it should work.

    Maybe the SD card not work properly, then try another SD card.

  • Windows Update does not work after restoring the system

    HP Compaq 6000 Pro, bought in early 2011. Windows 7 32 bit. I recently did a factory restore to return to a clean system using factory restore partition. The restoration seems complete ok, and I have a Windows 7 clean and functional configuration.

    However, the Update window will not work (and of course, it is now quite an old installation of Windows 7) it comes up with the Red Cross and the message "Windows Update cannot currently check for updates because the service is not running." Other notable issues that may or may not be related are: Windows Defender won't start not (0 x 80070564). HP Support Assistant reports it needs to update, but the update fails (because then it just says: it should be updated again)

    What I've tried so far:

    Verified that the BITS and the WU services are both actually run

    Uninstalled the McAfee antivirus software

    Tried to install Windows 7 SP1 directly (happens with "catastrophic failure")

    Tried Windows Update (wusa.exe) stand-alone installation / WU Readiness tool-fail (Oxc8000247)

    MS difficulty he said Troubleshooter it corrects problems, but nothing changes later

    (In short, tried all suggestions from MS support)

    It drives me crazy - any help will be appreciated!

    ISO should work, just be sure to download the version of Pro 32-bit.

    after reboot and installation of my graphic card drivers, I noticed that I have yet 2 "Bluetooth devices" (bluetooth device) and I don't have a Wifi connection. I am currently connected to my internet via an Ethernet cable.

    Here are some screenshots of my problems:

    The wifi card, if it's a minimap, as it is in the image, should have had two sons goes to the card wifi which were channelled through the case.  These were responsible for picking up the wifi signals to work.  Since the screenshot shows the weak or no signal, I suspect this is the question.

    As to describe the process of removing antennas, I couldn't find the following steps.

    Before you start: Remove the access panel, the collar, the higher optical drive and the upper bezel.

    1. Detach the antennas wireless the wireless LAN card.

    2. Cut the cable tie fixing connectors antenna for the front i/o cable harness.

    3. Pull the antenna cables without wire through the access hole in the upper part of the unit.

    4. Pick up each cable hooks fixing the top of the page of the PC.

    5. Detach the screws for each antenna.

    6. Pull the antennas of the unit off.

    In the end, it seems that the antennas are routed right under the top cover.
