automatic creation service_name to sleep while the other fails in standby mode

Hello

my environment:

1 primary, standby active 2

DataGuard without CARS

Fast-start failover active

DB 11 G 2

I wonder how to solve the following scenario:

Watch 'first' with noms_service 'first_sn' db fails.

Watch 'second' with noms_service 'second_sn' db is still in place as well as the primaries.

HOWTO manage creation automatic service_name on standby db 'second' due to the redirection of the connections client read-only?

in other words, as soon as one of the eve broke down, the other waiting Gets the service name from the database failed, as in this example the

Watch 'second' db would have these Service_Name:

view the service_name parameter

first_sn, second_sn

Thank you very much!

The trigger to start the service on the two standbys. The tnsnames would deal with the connection.

http://docs.Oracle.com/CD/B28359_01/network.111/b28317/tnsnames.htm#NETRF262

In light of what you really want you can avoid the trigger and use several address lists in your tnsnames file.

Best regards

    I'm guessing that you have created the Enum on the front panel.  If you right click and create an indicator, it corresponds to the type and be an enum.  LabVIEW represents enums as U16, but because the types are not the same (for example, your enum has 3 values, but a U16's 65 536 values), LabVIEW automatically converts value (or converts) the smallest representation (enum) in the largest value (U16).

  • Disk error when you exit the Portege M100 in standby mode

    Hello all :)

    Have a Portege M100 for general use with WXP Pro installed.
    Recently decided to upgrade to a DVD - rom DVD burner, then bought a Sony DW-Q250A burner.
    Installed and it worked, but I continue having problems when the computer wakes from sleep, I get the message "ERROR #1 IDE", while the system reboots without additional probs in windows

    The problem is, once this happens, the DVD player then disappears from the window 'my computer' and is not visible in the "Device Manager", until I remove the disc, back up and then analyze for pop. "p in Device Manager devices, it reappears as nothing has happened."
    I thought it might have been a conflict with the IDE bus (ie the two - disk HARD & DVD - disks configured as master) so I put a rider on the HARD disk to make the slave drive (which looks like to mean a change of firmware on the DVD drive for this) but it just created more probs... Then I got a message "ERROR of IDE #0" extra when I did and the machine would not boot from the HARD drive.

    Any thoughts would be welcome? :|

    Mark

    Hi mate,

    "first of all I would like to explain the IDE #0 error: it s quite understandable given that the HARD drive is the * FIRST * player of all and must stand the * FIRST" by car, which means that you jumper shouldn´t to a slave drive. It must be a master, otherwise, as in your case, the boot of won´t machine.
    in
    So you have 2 IDE channels (primary and secondary IDE channel), and each channel has a master and a slave. Apart from the HARD drive that is located on the main channel, your DVD player is naturally on the secondary channel configured as the master drive.
    Here´s a bit 'image': D to explain it:

    -> Primary channel-> Master = HARD drive
    -> Slave = nothing

    -> Secondary channel-> Master = DVD
    -> Slave = nothing

    Regarding your problem:

    I have no definitive solution for you, but I can give you some advice. First download the latest BIOS for your machine and upgrade to the latest version. Then download the latest drivers and install them. After that, look for an update of the firmware of your player of DVD and last but no less check the database of microsoft for known issues as any of the similar issues are known for me with drives toshiba toshiba machines.

    Would be worthy to try

    :)

    See you soon

  • When the computer remains in standby mode it will not start normally, usually ok in safe mode, but even when its up and running normally it's extremely slow.

  • Hearing: Cut a track while the other is active

    Hey everybody,

    I had a problem with Adobe Audition. I'm a beginner so the answer is maybe obvious but whatever.

    One of my friends Screen Shot 2015-11-16 at 18.16.14.png

    and recorded me a conversation we had on Skype. Everyone on his own computer. Therefore, we have two different tracks.

    Each of them we we was supposed to just record her own voice with a microphone, then I could change the two titles at the hearing to a normal and clear conversation. My friend accidentally recorded my voice (on Skype, that sounds horrible) on his trail also.

    Now I have a track with my voice and my friend and I (in a bad quality). The whole project is 1 hour long and it would be so so much work to just cut my voice its track.

    Now the question. Is it possible to cut the track whenever my title is active? (When my recorder is active). So that my voice on the track is muted when I speak on my own path? Or do my track (the upper one) kind of a track of dominant, so that it automatically cuts all other tracks when my voice is audible?

    I hope you understand what I mean. I'm working on a Mac with hearing CC 2015.

    I'm looking before hear you.

    Thank you very much.

    Yes, there might be a way for you to do this... it is known as "Chaining" side

    Chaining aside is a bit difficult to describe in a simple forum post, but this video tutorial gives a fairly detailed set of instructions on how to do it: Sidechaining in hearing CS6 | Short and Suite | Adobe TV Note that it says CS6, but newer versions of CC work essentially the same way.

    That said, depending on how long your material is, I could always go old school and do it manually using volume envelopes.  This would give me more control and precision that any automatic function could be used.  Once you start to draw envelopes on the track with two voices, you'll be surprised how fast you can go - it's probably a "one cup of coffee job" rather than work a full day of!

  • A computer can see devices multimedia, while the other computer cannot

    My Vista laptop can see my my Linksys Media Center Extender and Blu - Ray player in the "Network" window, but my Vista desktop does not see them.  Vista computers can "see" each other very well.  I can also ping the devices of media from the desktop.  The Office has been able to see two devices without any problem.  I tried to disable the Windows Firewall and AVG Anti-virus.  The two computers are running the same antivirus.  No luck.  What I forget?

    Well, just after I wrote this, I restarted once more (on the third or fourth time this afternoon), and now everything works.  I can't explain it.  I guess I will come back to this post if the problem comes back.  I guess I should add that I don't connect until the computer was sitting on the screen for 10 minutes at least (by chance), rather than the usual immediate connection.  Maybe another service needs time to start until I entered my password.

  • Automatic color correction with regard to the other layers

    Hello

    This thread is about Photoshop Color Correction the edges of a layer corresponding to the next layer below. Please see the image define:

    Untitled1.jpg

    I shot around 16 photos of the site above and less Photoshop > file > Scripts > load files into stack. After browsing and selecting my 16 stills, I checked "attempt to automatically align source Images". Above is the result. Photoshop fantascially aligned images, but because of the edges on separate layers, you can see the layers separately.

    My question is, can somehow, Photoshop can automatically correct the colors of the edges of a single layer, referring to the sub layer.

    Thank you
