How to change the headphone port #?

ENV: Oracle 10 g 2, RHEL 64 bit on ASM (10gr 2):

Current listening port is 1521. I was asked to change it to 10526 (please don't ask why :-)).)

I tried to change the port number in the listener.ora file, then restarting the listener, but the I start getting ' ORA-12541: TNS: no listener ' error. If I change back to 1521 and restart the receiver, I am able to connect to the database. What else should I do to change the posrt # please?

After I have change the port and restart it, here is what I tried to test:

$ sqlplus user/password@sid

...

ERROR:

ORA-12541: no listener

Enter the user name:

When I restore the port # change, I am able to connect.

Help, please.

Best regards

Very strange, LISTENING means that a listener is sitting on this port, so if you have not the 1521 and it works... I don't know, something is off – try to grep netstat for LISTENING.  If you have it on 10526 and this does not work, prolly local recording listener/static issue the other mention.  Also, the idea of the listener should wait for a connection request and then pass to another session-specific port.  No listener error means you have until now, but something bothers me about this, I know not what.

Please copy and paste all the production of the lsnrctl commands, to obscure details can be important.

Just to be clear, we don't talk to some listeners, ASM, right?  (Or conversely, they did not something rac on the upper port?)

    Hello world

    I just bought a new watch that should be able to communicate with a pc via the infrared port (it's the Polar S710).

    What you need to do is the following:

    -Stop application services
    -Change the port of database in listener.ora and tnsnames.ora
    -Bounce of the database and the database listener; Make sure that you can connect to the database using the new port
    -Change the port of the database in the context of database file
    -Start AutoConfig on the database layer node
    -Bounce of the database and the database listener; Make sure that you can connect to the database using the new port

    -Start AutoConfig on application-level nodes
    -Start the application services

  • How to change the http port in EBS 12.1.3

    Hi all.

    I configured App & DB to use the port 9 pool during cloning.

    For some reasones, I need to change the port http request 8008 to 8,000, but DB port must remain 1529.

    If I may continue the document: https://support.oracle.com/epmos/faces/DocContentDisplay?id=760590.1 ? My version of the EBS is 12.1.3.

    So I need only change my CONTEXT.xml lines (as in the example below) and run the automatic configuration on the Application layer? :

    < web_port oa_var = "s_webport" oa_type = "PORT" base = "8000" step = range "1" = "-1" label = "Web listening Port" > 8000 < / web_port >

    < activewebport oa_var = "s_active_webport" oa_type = "DUP_PORT" base = "8000" step = range "1" = "-1" label = "Active Web Port" > 8000 < / activewebport >

    < login_page oa_var = "s_login_page" > http://myhost.Oracle.com:8000/OA_HTML/AppsLogin < / login_page >

    < chronosURL oa_var = "s_chronosURL" > http://myhost.Oracle.com:8000/oracle_smp_chronos/oracle_smp_chronos_sdk.gif < / chronosURL >

  • How to change the number of default weblogic Portal port

    Hi all, I would like to change the number of port weblogic portal server by default to 80 in order to test.

    (1) can I change like that
    (2) in the affirmative, please let me know how to do this.

    I went to the file config.xml and search 7001, not able to find something with this number, able to see 7002. (The SSL port).

    Please put some light on this.

    Thank you very much
    Peter.

    Hi Peter
    1. Yes, you can change the default port 7001 to something else.

    2. If you have default Port 7001, it will not appear in the config.xml file. There are NO labels. So yes, when you searched 7001 you find IT. If you change the default port, you will have entered as shown below. If you change the default port, these port tags are shown in the config.xml file.

    3. stop the servers. Make a backup of the config.xml file. Within the tag xml from the server, as shown below, add these 2 labels carefully. Save the config.xml file. Restart the server. NOW, this means that your administration console is running on Port 80.
    80
    true

    Example of file config.xml with the default port changed to 80


    AdminServer

    AdminServer
    true
    demoidentity
    {3DES} qxEhrfmANIITdpvPld0Uvk5i/rPNDAmZ

    80
    true
    ...
    ...

    NOTE: You can also change of administration Console. Choose your thinking, the servers and the AdminServer. In the main, first tab and then click on lock and change change the default port 7001 to 80. Record. Click Activate. Immedialtey you will get errror Page not found. Because the url is still having 7001. You manually change the port of the url to 80. You will again see console. If I prefer, stop the server. Edit the config.xml file. Restart the server.

  • How to change the Port pool

    If we want to change the port pool after cloning of layers of DB and Apps, what is the best way to do... A single method, I know, i.e run the preclone on the target system and run config clone again once on the same target on both system layer of database and Application layer and change the pool of port...

    is there another method?

    How to change the host name of a component of Applications using AutoConfig Doc ID: 341322.1

    (a) to register the application of topology of net service model node
    (b) updated the context file Autoconfig
    (c) shutdown apps services
    (d) to run the automatic configuration service
    (e) change the name of the host at the OS level
    (f) restart the machine.
    (g) to start the application sercies

    In step 2, the context of the updated file, we will create the new context with the new hostname file... Here I have doubt, how come new context file will be created with the new host name, since it has not changed hostname at the level of the bone at this stage or before this step? AutoConfig will be CNET, because the Hostname of the Machine is different, because we change the hostname in the last step before

    Please clarify my doubt, if my understanding is wrong?

    In step 2, you run "perl adclonectx.pl" command. This script is used to clone your context file (i.e. generate a new), and it will ask you to enter the new host name. Once completed, you will have two files of context in the directory $APPL_TOP/admin:

    (1) _ .xml
    (2) _ .xml

    When you run the AutoConfig (step 4), you must provide the context new file generated (i.e. _.xml), and the model topology net services (which is clean, because we have already served there) will be filled with the new host name.

    why we cannot do the procedure below...

    (a) to enter the net service topology model applications pane
    (b) change the hostname at the os level
    (c) restart the machine.
    (d) update the context file with the new host name or create the new context file
    e run the automatic configuration
    (f) to start the services

    Please correct me if I'm wrong...

    I have not tried your procedure before, but I think it would work also.

    I hope it is clear now.

  • change the com port assigned to the fax and scan

    I used fax and scanning for once.  I had to move my external modem to a different port.

    I don't know how to change the windows fax and scan com port manually.

    the wizard does NOT start, I guess because the fax is installed and worked until I had to change the number of COM port...  I need to change the number of pot with hundreds of research, it seems that no one knows how to change manually the Compote in windows fax and scan, unless they use the wizard.

    my assistant does not start. I guess I'm 'old school' I don't need an Assistant, I need to manually change the fax uses com port.

    :-), it's frustrating because help said only: click "fax" in the lower left corner, and they all assume the installation wizard starts and everything will be fine. :-(

    the wizard does not start. :-(

    I am desperate to get my fax work and need to know how to set the correct port number in a system that is installed and running, such as the wizard never starts.

    for anyone who goes out at the end of questions and ideas, I have a fax application stand alone who is working with the new port setting. It's just not a good app for my needs

    Please?

    Thank you

    Post proposed by the moderator of the appropriate forum category

    Hi John,.

    You can follow the steps below to change the COM port for a modem:

    1. search the Device Manager.

    2 look for the Modem device, right-click on it, and then click Properties.

    • If the change settings button is present, you must click on it to make changes to the appliance. If the user account control dialog box appears, confirm that the displayed action corresponds to what you want, and then click continue.
    • If the change settings button is not present, the modem does not support the ability to change the modem settings. Refer to the documentation provided by the vendor of your modem.

    3. on the Advanced tab, click Advanced port settings.

    • If this option is not displayed, the modem does not support the ability to change the assigned COM port. Refer to the documentation provided by the vendor of your modem.

    If the same persists, we suggest that you post your query in Microsoft TechNet so that their support team will provide you in-depth assistance.

    Kind regards.

    Does anyone know how to change the name of the virtual switch (used by VM) without braking the VM running in this cluster?

    The best way to do this without losing network connectivity is add a group of ports with the new name and connect the virtual machines to the new group of port and when the initial group of port is empty remove - remember that it's the port group named not the vswitch.
