Question 11 GR 2 listening port

• Remote listening port

  Hi all
  
  I have oracle 11g rac ASM in RHEL5
  I have 2 nodes
  node 1 VIP 115
  node 2 VIP 116
  for each of these nodes, I local listened as oracle said, I also have remote listener
  witch is listen to these two nodes and do the load balancing and my remote interlocutor is set to SCAN ip like oracle
  
  My question is:
  the remote listener is resident in what node because I found the listener even also reside remotely in nodes 1 and 2
  When the connection is came to the listener (distance) of the database is also detect that new connection is coming and then
  to see which node is have less load and pass this connection to the local listening port, so I need to know the remote listener
  reside in the nodes 1 and 2 or... I don't know?
  
  
  Thank you very much

• Select < of the Listener Port number > in which_table?

  I am writing a SQL script which, among other things, disconnects from Oracle and then reconnects to the same instance under a different name. I'm able to query v$ database and v$ instance to get most of the information I need (host, name of service, etc.) for the part of reconnect. The only part that miss me is the listener port number. I could hardcode it 1521, but it's not very flexible. Currently, I am asking the user (who is usually me) for the listening port number in the SQL script, but that just seems a little lame. So my question is this: is there a view or a table somewhere in the schema sys that I could use to display the configuration of the earpiece? I work mainly with the gr 10, 2 + databases.

  No, I don't think that that is maintained in one of the views and is not soemthing that you should believe would keep have changed (if the implementation of the network people are good). In order to check once and you should be fine.

• Wireless Pan DHCP Server will not start... Error: Static Interfaces/Listening Ports not available

  I had trouble not getting no connection with WiFi, after weeks of allsorts following advice on forums etc, I found that the Wireless Pan DHCP Server does not start with error: Static Interfaces/Listening Ports is not available. my understanding is that the ports UDP 67/68, but when I run a Netstat I don't see them in the list. I checked windows firewall and they seem to be set to DHCP.

  Any ideas would be useful.

• Change the listening port for SSH on IDS

  Should what command I use to change the listening port on an IDS 4200 series? I listen on another port, and when I applied the S189/S190 update, it changed SSH port 22.

  Just out of curiosity, too, no one knows what else S189/S190 updates change?

  Thank you

  Cisco supports only configurations using the CLI interface. The ssh port cannot be changed through the CLI. Modifying the files in config system via the service account is not a good idea and not supported.

• How can I display an error message on the listening port close popup without closing the popup.

  Hi Experts,

  JDeveloper 12.1.3.0.0

  How can I display an error message on the listening port close popup without closing the popup.

  Thank you

  Roy

  As its name suggests, close listener of popup is called when popup is closed so you can not do this.

  If you want to display the popup message, use your own buttons instead of the ok/cancel default buttons and close the popup programmatically.

• How to change the default listening port?

  Hi all

  11.2.0.4

  RHEL 6.5

  I managed to install Oracle Db 11.2.0.4 on RHEL 6.5

  He created a default listener uses port 1521.

  With the following entries in listener.ora.

  listener.ora # Network Configuration file: /u01/app/oracle/product/11.2.0.4/db_1/network/admin/listener.ora

  # Generated by Oracle configuration tools.

  )

  )

  ADR_BASE_LISTENER = / u01/app/oracle

  How can I change the port in 1522? Can I just he replace value of listener.ora?

  Should I also change the value of KEY = EXTPROC1521 to KEY = EXTPROC1522?

  
  

  
  

  I tried to change the port in 1522 in the listener.ora but when I start "lsnrctl status".

  As said earlier after which the listening port, you must update the parameter local_listener database as below:

  ALTER system set local_listener ='(ADDRESS = (PROTOCOL = TCP) (HOST = ip-10-0-0 - 216.ec2.internal)(PORT=1522))'

• APEX does not open after you have created the new Oracle listening port

  Link to your thread to listen would have helped: Oracle XE 11g with Apex No problem of Listener (ORA-12541: listener TNS:no)

  It seems that your listener uses the static instance via the listener.ora file registration and missing entries for the http service. Edit your listener.ora (F:\Apex_Installed\app\oracle\product\11.2.0\server\network\ADMIN\listener.ora) file and add the following entries in the listener.ora file DESCRIPTION_LIST. Then, restart the listenerer.

  (DESCRIPTION=
    (ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=8080))(Presentation=HTTP)(Session=RAW)
  )
  

• default listening port no

  I use 10g release 2 under oel 5.5 inside vmware
  I want to create multiple listener to my database and aal of them to be registered dynamically
  I had created two earphone using netmgr one is by default is not set by default to port 1522
  Here is my listener.ora file
  
  AUDITEUR1 =
  (DESCRIPTION =
  (ADDRESS = (PROTOCOL = TCP (PORT = 1522))(HOST = pawii.oraexpert.com))
  )
  
  LISTENER =
  (DESCRIPTION =
  (ADDRESS = (PROTOCOL = TCP)(HOST = pawii.oraexpert.com) (PORT = 1521))
  )
  
  I want to record dynamically
  
  I pulled lsnrctl start
  and lsnrctl start (no default listening port) auditeur1
  both the listener don't start but the default receiver support no no services
  I had bu db start again its not supporting all services why?
  and if I specify services database with the help of netmgr then the entry goes in listener.ora and make static recording which always show status unknown
  so, how can I do dynamic registration?

  You must indicate your instance where are listeners. Run these two commands:

  alter system set local_listener='(address_list=(ADDRESS = (PROTOCOL = TCP)(HOST = pawii.oraexpert.com)(PORT = 1522))(ADDRESS = (PROTOCOL = TCP)(HOST = pawii.oraexpert.com)(PORT = 1521)))';
  alter system register;
  

  and the registration will then be automatic.

  Hello

  I updated the apex listener port 8080 and it does not give this error now.

  However, he always says "Database connection by default not configured correctly"

  I gave the name of SID as xe, which is the default value and that the correct SID for my DB also.
  >

  SID = xe is correct since you are using 11g XE.

  What is more important, is that you may be able to access the Apex Application Builder via the ApexListener or not.
  If Apex is not accessible, then the thing to check would be the Apex_Public_user password. Can you connect to XE using Apex_Public_user with the password that you provided when setting up the ApexListener?
  Also make sure the Apex_Public_user and 2 other users ApexListener 2.0EA, are UNLOCKED.

  See you soon,.

  If the scan is set up then you do a connectivity with listener to scan, you can check the scan as a listening port

  Yes. However, should not be used the same pool of port on the nodes of level apps/db.

• Add Service to the new listening port

  Hello
  in my GI 11.2, I added a new listener of cluster, listen to the 1525.
  My database has 2 service and MICKEY MOUSE.
  I need to sign Mickey on the standard earpiece (1521) and the MOUSE on the new listening port (1525).
  Is it possible?
  
  Thank you

  NO.

  The two databases will save itself against port 1521 in any case.
  Also the second listener is redundant in any case, there is no need for this.
  The headphones are brokers only, there is no permanent connection and you lose just resources.

  RLY thx for the help I'm dsapointed :/
  
  I tried to use a sample listener.ora, but got the same error, the file is not ignored, but it doesn't work.
  
  There is no listener proc, I need to have a process like that, I guess:
  
  /U01/app/Oracle/product/11.1.0/Db_1/bin/tnslsnr inherit LISTENER
  
  I don't see anything on port 1521:
  
  netstat | grep 1521
  
  Did not pass 10g and 11g

  Set permissions on referenced dir:

  sntuscrt: cannot create dir /var/tmp/.oracle

  Tip: instead of posting/check together .trc file content, it is often enough to write the article nserror and a few lines before, at least to start with.

• Database - listener Ports - data transfer

  Hello
  
  If there are two databases running on the server, is it opt to configure the listening port only for two databases? and what happens if a single listening port configured?
  
  Thank you

  Hi Jgarry/Hemant
  
  For client-server data.
  
  I understand as
  
  First, the client sends the request to the db server, the Listener listens to the connection and creates a database server process to handle the request (can be a query...
  
  I just want to understand how the processed information passes to the client... I wanted to say... What are the ports to transfer data from db to the client server?
  
  Jgarry, I understand the flow of data occurs via a separate data port (for example it can be any port 1599 or something)... So not that any additional traffic occurs between the client-server or client-server use the same data port?
  
  Im trying to understand the architectural flow of connectivity between the customer and vice versa. that will help better understand.
  
  My concern is...
  
  We implement a customer through TNS names connectivity. The listenes connectivity server and creates a server session to run the connectivity. Just as a request from the client to the database listen service_name "orcl", host = protocol = TCP port = 1521 abc.com. that is listening on the side Server and server recoganize the connectivity...
  
  Here, I am trying to understand... once the connection is established, so it's not need a listening more. We can not even stop the listener. How the portocol TCP in the Oracle Net will establish the flow of data between servers (how goes the sequence of request and response).
  If the network TCP layer is used to interact between the servers then how data flows between servers; as it uses a port number separated to send/receive data.
  
  Thank you

  Thanks in advance

  (added the more information about the data flow between the client-server)

  See the "Architecture of the listener" section here:
  http://download.Oracle.com/docs/CD/B19306_01/network.102/b14212/architecture.htm#sthref429

  1. a customer identifies the listener of the tnsnames.ora entry and/or command-line (HOST/IP, Port) settings.
  2. He sends the requested SERVICE_NAME / SID to the listener when it is able to connect to the listener.
  3. the Auditor verifies that he is aware of the SERVICE_NAME / SID (if not, it returns an error "listener isn't aware of service"). 'Consciousness' is inspired by PMON the recording with the listener database and/or the SID is used in the listener.ora file.
  4. once the auditor confirms that such a SERVICE_NAME / SID is available...
  5. He requests the service of database at the table a new process (which you will see as a process of oracleSID on a Linux/Unix server or a Thread in the process oracle.exe in Windows).
  6. it transmits customer information (IP address of the client, Protocol, etc.) in the process.
  7. Subsequently, it is this server process which is the authentication of the user (name of username-password), creates a session and manages all client requests (instructions SQL etc.) and returns the results to the client.
  -The listener is no longer involved.
