HOW can I identify which instance is associated with what listener

Hi all
I have created a DB instance. Suppose that named 'B '. but there is already another this DB instance. Named 'A '.
Then, I created a listener instance DB 'B '.

Now, my what, is that HOW can I identify which instance is associated with what listener.

(2) if I create listener can also created service. If I stopped that service and then I can fire the query or Login again, WHAT will be the expected result.
I tried to ask people of my answer. but not convinced.
Please help me for this.
Thanks in advance

A listener is able and sufficient to deal with all the instances running on the computer. You are supposed never to create a listener instance. So in your case, the other instance B would be also recorded with the already present litener as well as the existing instance.

(2) if I create listener can also created service. If I stopped that service and then I can fire the query or Login again, WHAT will be the expected result.

Have you tried looking in this area and see what would be the expected result?

Services are a means through which handles things. And when the service would cease, it means that this particular thing also will not work. Now, do you understand what the listener is actually used for? It is intended to listen for incoming connection requests. So if you turned it OFF, you cannot send to your db.

I tried to ask people of my answer. but not convinced.

Before asking people, please read the documentation that covers all these things in a large part. Check it out at http://tahiti.oracle.com.

    See the listener.ora file. It is usually $ORACLE_HOME/network/admin/listener.ora

    You can see what listener is associated with a file.

    Details will generally be like this

    LSNR1 =
    (DESCRIPTION_LIST =
    (DESCRIPTION =
    (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP) (HOST = instance1)(PORT = 1666))
    )
    )
    )

    LSNR2 =
    (DESCRIPTION_LIST =
    (DESCRIPTION =
    (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP) (HOST = instance2)(PORT = 2666))

    A listener is used when a client wants to connect to the database server. If you connect directly to the server without using the name of the instance, then you can connect even if you stop the service.

    Check it,

    But if you try to connect from a client, or use the name of the instance, while connectineg
    you get the error like that,

    SQL> conn ganesh@ganesh
    Enter password: ******

  • How can I determine which commands are associated with private 2-14

    I don't want to create command authorization sets just used a private level. I can't determine what commands are assigned to what level priv?

    By default, there are three levels of command on the router:

    privilege level 0 — includes orders to disable, enable, exit, help and logout.

    privilege level 1 - Normal level on Telnet; includes all commands on the router user level > prompt.

    privilege level 15 - includes all orders enable-level at the router prompt #.

    Orders at level 2-14 are empty by default, BUT you can always access all orders at your level and below, so if you are level 4 you have access to the commands at levels 0 and 1

    Hope that helps, rate, if

  • What is the order of the removal of the songs to an iPod Classic syncing > somehow my laptop has started the process of synchronization without my knowledge and removed approximately 2,000 songs of my iPod classic.  How can I identify which were delete

    What is the order of the removal of the songs to an iPod Classic syncing > somehow my laptop has started the process of synchronization without my knowledge and removed approximately 2,000 songs of my iPod classic.  How can I identify which were deleted songs?  I always manually move files to prevent this.  I'm on Windows 10.

    Has no way to know that...

    If your library iTunes music fits on the storage space of 160 GB of your iPod classic, you just set to automatically sync your entire library of music.  Then, it won't matter which has been removed and which do not get deleted, because your iPod music library is the same as your library iTunes music.  And iTunes it keeps this way, every time your iPod connection (or click sync , if already connected).

    If you don't want "everything" in your iTunes library on your iPod (understandable), you can create a playlist in your iTunes library with all the songs you want on the iPod.  Then, set to automatically synchronize the playlist to iPod.  Instead of manually managing iPod, you manually manage playlist in your iTunes library.  The iPod has no need to be connected.  The next time you connect the iPod (or click sync , if already connected), iTunes will update the iPod with the same changes.  The big advantage is, if something happens like what you describe, or needs to restore iPod (erased) or even if break you your iPod (and get a new), need you a few mouse clicks to solve the problem.  Just set it up to sync the same playlist once again, which exists in your library iTunes (not only on the iPod).

    You can post back for more information about how to use automatic synchronization to do what you want more easily, go ahead.

  • How can I fix Runtime error R6034 associated with ITunes in Windows 7 than?

    How can original title - I fix Runtime error R6034 in Windows 7?
    I use Windows 7 Home Premium 64 - bit OS.

    I've never had this problem before... today, I opened iTunes and it prompted me to download the new version.  I use iTunes all the time and have updated several times without any problems.  During installation, it gave me an error message that says:

    Runtime error!
    Program C:\Program Files\iTunes.exe
    R0634
    An application has made an attempt to load the C runtime incorrectly library.
    For more information, contact the application support team.
    I leave the facility, uninstalled iTunes and rebooted my computer.  Now, I get a similar message with a slight difference:
    Runtime error!
    Program C:\Program Files (x 86)...
    R0634
    An application has made an attempt to load the C runtime incorrectly library.
    For more information, contact the application support team.
    I don't let anything go to the error message.  It does not point to a specific file, it ends only with "(x86)..." "Whenever I start my computer, this error message appears on my desktop.
    How can I fix this problem?  I found several solutions but am not sure which one is the best, and I don't want to try a bunch of different things for fear that I can make the problem worse.  I would try and it staring at me, if possible, but I need to know if this is really possible or if I have to take my computer to someone for repairs.  Any suggestions will be greatly appreciated!

    I checked this page https://discussions.apple.com/message/24611030#24611030 and it cleared up the problem, although I have not tried to reinstall iTunes - it installed on my desktop without a hitch and synchronize the iPad to that instead.  But it was very satisfying, removing every piece of software my laptop Apple.

  • How can I remove a plug-in association with files?

    I don't know if it's something I can change specifically, but here goes. I work with InDesign CC 2014 on a mac under OS 10.9.5 (relevant?).

    We have a number of files of type 'Master' with several layers. Here's my problem: at the rear, we installed a plug-in of XMPie. Unfortunately, we never really ended up using it (at least for now). However, all of our files in the meantime become associated with this plug-in. We have recently updated the Adobe software and the plugin is not compatible. How can I remove the association with the plugin without having to re-create the file? Is it still possible?

    "Adobe InDesign cannot load the XMPBackEnd7_5.InDesignPlugin plug-in. The XMPBackEnd7_5.InDesignPlugin plugin requires version 7.5 of InDesign. Contact the vendor for a compatible version of the XMPBackEnd7_5.InDesignPlugin. »

  • How can I identify which uses a color in a document?

    I work with two other "designers" and manage to set up the complicated press art files. All used "add" color options brings up several shades that are used in the documents. Unfortunately neither one of these designers are savvy print and used multiple versions of the same color and some are PMS spot; Some are CMYK spot; Some are CMYK processes; Some are RGB and still other LAB. Its a mess. I need to identify what type of objects / use a particular color so I can fix it for the press. It is an excellent option for this in InDesign, but how to do this in Illustrator?

    Window > separation preview

    Turn on overprint preview

    Option and then click on the eyeball of a color solo that only, repeat color option click on same eyeball to show all new

    CMYK works as a group with the option click, so you can solo and show what is in 4/c or easily spot
