tnsping shows no listener

Hi experts,

On a 11.2.03 no rac installation on one machine virtual OEL 7, I get a weird error. Even if the listener is running, I'm not able to issue a tnsping to the DB instance. The DB instance is also running.

{code}

Hello

I know it's late, but I was finally able to remember exactly how I did it...

I can see what your problem is...

is not within the oracle... Since you have multiple IP addresses, configure you the IP address port forwarding internal to external. It is not fake, but you need the nt to connect to your virtual machine using PuTTY.

Here's what I suggest you do that, since I am not a guru of networking. Just keep it Simple

  • donot keep multiple IP addresses.
  • Remove Port forwarding NAT adapter and just keep HOST ONLY
  • Change the IP address of your machine to the same subnet as your local physical computer.
  • disable the dhcp, dns and use a manual IP address on the same subnet.
  • Restart network services
  • ensure that ifconfig shows the new IP address of your device (eth0)
  • Use this IP address to your listener.ora and tnsnames.ora
  • test the tnsping and listener State.

To allow all traffic and bypass firewalls, here is the command that you can use.

iptables-a INPUT-i eth0 Pei tcp - dport 22 - m state--state NEW, established-j ACCEPT

iptables - an OUTPUT o eth0 Pei tcp - sport 22 - m state - state ESTABLISHED-j ACCEPT

Thank you

  • Problem with the listener in environment of multiple databases

    Hello world!

    I have a server that is running about 10 databases. And 5 listeners who manage these databases. Some listener manage 1 DB, another can handle more than 1.

    Listener ESSENTIALS that I create the first run (top of the listener.ora file), only 2 DB. But when I show the status of the listening port, it shows the listener to manage all DBs.

    Another listener works normally.

    Could you help me solve the problem?

    Thank you!

    TuanNV

    You must set the LOCAL_LISTENER parameter in each instance to control what other they register with. You have probably enabled by default, so they all register with all that is listening on port 1521.

    Moreover, some people here get mad at the idea of running more of a listener. Be warned.

  • With regard to Apex configuring the listener using Weblogic Server.

    Dear all,

    Well, I have configured my interlocutor Apex in my Web server and everything worked fine. But my requirement is like I need for my URL should like this format http://hostname/ReportServer: port/dev/apex but by default, as we know it comes as http://hostname/ReportServer: port/apex/dev (as I gave the url mapping path/dev). So I tried by changing its name as DEV while deploying the APEX. File. WAR and I gave the root context than dev. Now question is even if configuration directory given i like "dev" but still its showing as 'Listener not configured'. Pls someone help me in this. Help is very appreciated.

    My configuration file is "/home/oracle/apex_listener.2.0.3.221.10.13/dev"

    But even once apex named subdirectory is created inside this dev automatically.

    In regards to this link, I had an idea but its incomplete since his unanswered, so I'm bit confused too.

    https://community.Oracle.com/thread/2134379

    I thought to change httpd.conf file and give redirect URL but I'm not sure that can we redirect modulewise as separate 'apex' named subdirectory is created in "dev" then configuration gets effect as how it will work and mod_rewrite option I have seen but can't understand as including one to pick up. Please suggest...

    My Version of the apex is 4.2.3

    Apex listener Version is 2.0.3

    As appropriate, any other information please ask me.

    Kind regards

    Nitesh Perron.

    Dear all,

    Finally I found the solution for this.  I put here so that it can be useful to others who may face difficulties like me,.

    Floorconstruction:

    After changing the root of context just start your deployed war file and test it.

    While reaching the URL,

    Web page showing "listener apex not configured" and it will show you the location of the configuration on the Web page itself.

    Then you simply copy all directories and subdirectories (that were created when you set up your database using the file. War) at the location that shown on the Web page.

    As we change the root context so a named directory context root allows to create inside the path configured, if web is unable to find configurations because it happens inside the different directory so just copy everything and try. It worked for me very smoothly.

    My position was ' /home/oracle/apex_listener.2.0.3.221.10.13/apex"(before changing the context root in weblogic server).

    Then after the change and start the deployment once again, it became ' /home/oracle/apex_listener.2.0.3.221.10.13/dev', since I gave my root of context like "dev."

    So here I just copied directory "apex" on the dev directory and it worked fine and I got my desired URL as http://localhost:port/dev/apexhttp://localhostport .

    And all applications also works very well.

    Still, I felt its not correct way to view security, but this is the solution I found and I will try apache to redirect my URL.

    Thank you

    Kind regards

  • How to unconfigure a listener after command drop database

    Hello

    OS = RHL

    I have two questions small but important for me please.

    (1) I want to delete one instance 10.2 including full Cup out of the ASM instance (instance ASM has other instances registered too). I did not privilege y to set the display, so the only option is to manually.
    -For this, I found that I can use the command sequence:
    shutdown abort
    startup mount exclusive restrict
    drop database
    # I read that DROP DATABASE command will also remove all the data files, controlfiles, redo logs and spfile (init.ora file not and the password if necessary). How can I 'ls' or confirm related control files are also deleted (for example + DATA01/db/control01.ctl)

    (2) second, I want to stop and disable configure the listener also.

    PS to the | grep LISTENER shows 4 listener, but I want to stop only 1 and then I want to remove/disable-configures it. How do I do this

    Thank you very much in advance.

    Best regards

    Hello

     How can I "ls" or confirm that related control files are also deleted (for example +DATA01/db/control01.ctl)
    

    You can do the following

    asmcmd
    ASMCMD> cd +DATA01/db/
    ASMCMD> ls
    
    2) Secondly, I want to stop and de-configure the Listener also.
    
    ps aux | grep LISTENER shows 4 listener, but I want to stop only 1 and then I want to delete/de-configure it. How I can achieve that
    

    check the listener where the name of your DB

    lsnrctl status 
    then stop
    lsnrctl stop 
    from above O/P you can find out the path of Listener Home
    remove the Entry of your DB from listener file.

  • What host and Service using TNSNAMES


    Hello

    I created a cluster 2 nodes (LAB4 LAB5) in 11 GR 2 grid Infrastructure, which currently holds my ASM Instance cluster

    I'm trying to determine which setting host and Service name I should use on a client to allow connect to ASM as a local connection to the node and connection of cluster.

    I'm tresting 3 types of assemblies of TNS below

    + ASM1 - a simple connection to the ASM instance directly LAB4 as if she was not grouped

    + ASM1_VIP - I think that it is of the old method of 10g to connect to the cluster?

    + ASM1_SCAN - I think it's the new way to 11 GR 2 to connect to the cluster?

    * I don't use DNS / GNS - where the 3 inputs static analysis

    So I put my client TNSNAMES as follws-

    The reason for the 3 types of connection, I mentioned at the beginning of this forum

    #ASM instance on LAB4 via public IP

    + ASM1 =
    (DESCRIPTION =
    (ADDRESS =
    (PROTOCOL = TCP)
    (HOST = lab4)
    (PORT = 1521)
    )
    (CONNECT_DATA =
    (SERVICE_NAME = + ASM1)
    )
    )

    #ASM instance on LAB4 via VIP audience that is the old method of 10g to connect to a cluster

    + ASM1_VIP =
    (DESCRIPTION =
    (ADDRESS =
    (PROTOCOL = TCP)
    (HOST = lab4-vip)
    (PORT = 1521)
    )
    (CONNECT_DATA =
    (SERVICE_NAME = ASM)
    )
    )


    #ASM instance on Cluster via Public Cluster SCAN, i.e. the new 11g method to connect to a cluster

    + ASM_SCAN =
    (DESCRIPTION =
    (ADDRESS =
    (PROTOCOL = TCP)
    (HOST = cluster1-scan)
    (PORT = 1521)
    )
    (CONNECT_DATA =
    (SERVICE_NAME = ASM)
    )
    )

    The good thing is that a TNSPING to my client to all the 3 entries above, succeed

    Q1. Name of the Service don't know '+' i.e. that why for the + ASM1_VIP and _ASM_SCAN entry above, I could put neither ASM the SERVICE_NAME and not + ASM?

    Q2. I presume that for the method of 10g - the name of the Service be indeed ASM and not ASM1?

    Q3. If LAB4 should fail, my other node, LAB5, would inherit of the LAB4 VIP

    Thank you

    Jim

    Hi Jim,.

    SCAN is for the client computer access to the clusterdatabase without having to know which server in the cluster is to serve the db. SCAN is for your normal databases NOT the asm instance, your customers do not need to access.

    To connect to your instance asm on each node with sqlplus and get an output of:

    See listener parameter setting

    It will show, that asm has local defined listener and will register with the listener node running on your virtual IP address. It will not appear an entry for the remote listener.

    For your no - ASM databases, you will find set remote_listener parameter and pointing to SCAN listeners usually via an entry in the tnsnames like this file:

    MYDB =

    (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP) (HOST = your-rac-scan-name)(PORT = XXXX))

    (CONNECT_DATA =

    (SERVER = DEDICATED)

    (SERVICE_NAME = mydb)

    )

    )

    lsnrctl status

    -> you will get the output of the listener node

    lsnrctl status LISTENER_SCAN1

    -> you would give the output of the listener to scan if SCAN1 runs on the node of your ssh shell is sitting.

    Concerning

    Thomas

    Any listener residing on 'localhost', NEVER connectable from a remote client.

    For the listener to accept the connection of the remote client request,
    then listener must reside on the host using some routable IP #. other than 127.0.0.1

  • How to add an entry to the TNSNAMES file. ORA?

    Hello

    If I add the following entry to the TNSNAMES file. ORA:

    test1_10.121.34.56 =
    (DESCRIPTION =
    (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP) (HOST = 10.121.34.56)(PORT = 1521))
    )
    (CONNECT_DATA =
    (SID = test1)
    (SERVER = DEDICATED)
    )
    )

    How could I activate it please without having to reboot?

    I use Oracle 9i Release 9.2.0.8.0 to 4.7 CentOS
    Linux (which is compatible with RHEL 4.7) machine.

    Thank you

    Why is - that point to a host to 10.121.42.81? Your output of lsnrctl shows the listener running on ablora01.internal.XXX.com (at 10.121.42.100) is tuned for 'test1 '.

    Test1 and bochum are running on the same computer?
    If so, that was the 10.121.42.100 machine?

    Your output said no listener when you tnsping test1. This means that there is no listener clocked at 10.121.42.81.

    And my real goal is to allow a program to 10.121.42.81
    to connect to the instance "test1".

    The ip address (or host name) in tnsnames.ora specifies where the database . It has nothing to do with where lives the client (your app).

  • YouTube the sound cuts in and out

    In recent days, the videos YouTube is, at times, distorted, cuts in and out. This phenomenon appears only show all listening with, wireless, headset. When I disconnect the headphones and listen through the speakers of the iMac, the sound is normal. Also, AFAIK, the phenomenon isn't that videos of YouTube in Safari or Firefox, not iTunes internet radio, videos played in media players etc.

    I listen to the videos on a background of radio internet iTunes, and when the problems of its manifest, the sound of internet radio iTunes is smothered. Returns to the top of the normal when the distortion stops, and when I stop the video playback.

    I tried uninstalling and reinstalling adobe flashplayer (latest version), I deleted the browsing history, cache and cookies. Did not help.

    El Capitan, Firefox, Safari, latest versions.

    Someone has any idea how to solve this problem?

    I think that I thought about it.

    But first, I have to clarify that not all YouTube videos deal with this problem of sound. Only certain channels, no problems with other channels, except where they included third-party clips in their videos.

    I read somewhere that the headset and the computer must be plugged into the same power strip. I checked that. They were (Belkin Surge Master). So I tried to plug in the headphones to a different power strip (regular, plugged in the Belkin Surge Master), and of course, the problems of sound disappeared as if by magic. If anyone has an explanation for that, I'll be glad to hear.

  • Import of Crumplepop shining in fcpx

    Hi, can someone advise on how best to bring a Crumplepop shining in FCPX. Of course, I can import them into a new library but that would not restrict their use in other libraries? Is it possible to get them so they show and listen to extracts in the generators or the effects tab?

    Thank you

    You can work in the libraries., take a look at this discussion of additional context.

  • Help with router, crashing, mario kart wii, question

    I seem to have trouble with my router, I have the latest firmware installed and have tried repeatedly to re write the firmware for the router BEFW11s4 V 4

    1. when I go on a site for example bbc.co.uk/radio1 and try to listen live at a show, or 'listen again' my router goes down, and I have to restart my router every time.

    2 - while connected to the router using the nintendo wii, after 20 minutes of online game an error message saying that I need to restart the wii. and the game closes its doors, this seems to be a problem with the exact configuration of my router after a google search, and a lot of people have mentioned certain ports need opening, but I'm really not sure on how to do this, as I don't want to spoil things.

    any help appreciated, Lee

    I ended up buying a new router wrt160n and its solved the problem

  • Can I disable the Terminal Services if I don't use remote assistance/remote desktop?

    I use can I have Vista 32 bit home premium

    I thought that Vista have no remote desktop? Is not Terminal identical remote desktop services?

    When I go

    MyComputer > right click > properties > remote adjustment

    the box for "Allow remote Assisnatnce" is NOT COCHEE

    But when I run Netstat - ano, I see that port 3389 is listening svchost.exe process when I checal what services are related to this particular svchost.exe, I see the following services:

    Cryptographic services
    DNS client
    network location awareness
    KtmRm for distributed transaction coordination
    telephony

    and Terminal Server services

    Seems to be at a point several years ago, I allowed someone from microsoft to help me through the assistance at a distance could therefore have enabled or downloaded services Terminal Server?

    In any case, I think that Terminal Services is initially port 3389 to remain open and thus get an unsolicited connection attempts from different IP addresses.

    I tried a little experiment and finished the Terminal Services and changed the status of manual start-up. When I still ran netstat - ano, he showed no listening on port 3389

    However, when I rebooted my computer Terminal Server was running again. So I ended it again but this time off the service. When I fell net stat - ano he showed terminal services does not. then when I restarted my computer, Terminal Server services do not have turn on port 3389 has not been shown that listening

    SO my question is, as a user of Vista which doesn't use remote help desk or remotely.

    1. I CAN keep the disabled Services Terminal Server?

    2. it cause me any problem of operation or security if she stays in the disabled state?

    3 have disabled will cause me to not be able to get the scheduled updates?

    Thank you

    But I have been informed by Norton Personal asa require a Terminal Server Services be, nit for the part of remote assistance, but for other reasons. They say I can't turn off
