• Listener.ora to PROD and EVE

  Hi all

  I am Eve configuration that follows doc 469493.1 .

  I have a small doubt in why he mentioned not all changes in listener.ora?

  There is no change for listener.ora to prod and standby? Or just forgot me.

  Thank you very much

  You are not required to change the configuration of the earpiece, unless you use a different port of 1521. If you are using port 1521, then main bodies and relief will be recorded with the listener very well.

  That being said, I never count on automatic registration in my primary/secondary case for two reasons: 1) I like to define my transport settings and 2) I enjoy using DGMGRL. I'll explain more...

  (1) I'll be shipping again from the primary to the wait. This can be a lot of network i/o. Standard TCP buffer sizes and parameters of SDU are often inadequate if you have to redo any volume transported.

  (2) I encourage/recommend/advocate the use of the DG broker. The DG Broker makes failovers or passing a command of the singular instead of several actions. The DG broker means I use use Enterprise Manager 12 c Cloud control to manage and interact with my primary/secondary environment. If you use the DG broker, so you cannot rely on registration to the Forum because when the broker performs the operation of failover, it will bounce the instance when the instance will be is no longer registered with the listener. It breaks the failover operation. But put the registration information in the listener.ora, the failover operation works very well.

  Here is my listener.ora:

  LISTENER =

  (DESCRIPTION =

  (ADDRESS_LIST =

  (ADDRESS = (PROTOCOL = tcp)(HOST=myhost) (PORT = 1521))

  (ADDRESS = (PROTOCOL = ipc) (KEY = extproc)))

  SID_LIST_LISTENER =

  (SID_LIST =

  (SID_DESC =

  (SID_DESC =

  (SID_NAME = plsextproc)

  (ORACLE_HOME=/u01/app/oracle/product/11.2.0.4)

  (= Extproc program)))

  I put this in the listener.ora on the primary and standby. In this way, they have the same configuration for the day, I have to perform a failover.

  See you soon,.

  Do I need to SID_LIST_ parameter in the listener.ora in 11g file?

  We do not know who.

  LOCAL_LISTENER for each DB init.ora parameters is not an alternative to the SID_LIST_ parameter in the listener.ora file layout?

  Not exactly.

  SID_LIST_ serves static registration, which means that the database will be saved even stop and can be started remotely.
  It is also used to connect to a remote database in the NOMOUNT State, for example in the case of active RMAN duplication.
  Specifying LOCAL_LISTENER, the database is dynamically registered the listener in NOMOUNT (blocked), MOUNT, OPEN State.

  I would add SID_LIST like below in the listener.ora

  SID_LIST_SNOOPY =
  (SID_LIST =
       (SID_DESC =
       (ORACLE_HOME = /u01/app/oracle/product/10.2/db_1)

  Depends on. LOCAL_LISTENER will take care of the dynamic record at MOUNT and OPEN State. If you need more, go to SID_LIST_.

• SQLNET.ora and tnsnames.ora, listener.ora btwn difference

  Hi all
  
  What is the fundamental difference between these 3 files - sqlnet.ora, listener.ora and tnsnames.ora?
  
  Version may be 10 g.

  (a) Listener.ora is a SQL * Net configuration file allows you to Configure listeners (needed to accept applications for remote connection) Oracle database.

  Normally, this file resides in the ORACLE HOME\NETWORK\ADMIN directory or in the directory defined by the variable $TNS_ADMIN.

  (b) Tnsnames.ora is a file that is used by oracle client to connect to the oracle server.

  (c) Sqlnet.ora is a text file that provides SQL * Net with the basic configuration details as options vectorization, field by default, encryption, etc.. This file is located in the ORACLE HOME\NETWORK\ADMIN directory.

• Modify the file Listener (listener.ora) to remove PASSWORDS

  Oracle 10.2.0.4
  64 bit SPARC Solaris 10.5
  
  We have our listener that is locked by password user authentication. As Oracle has recommended, should not the authentication of users, leading to the decision to withdraw the following:

  #---15: 38:18 - ADDED BY TNSLSNR October 29, 2007
  PASSWORDS_MYDB = 8E28G2195BB5339
  SAVE_CONFIG_ON_STOP_MYDB = WE
  #--------------------------------------------

  My Solution:
  1 stop listener < nom_recepteur > and change the lines above in the listener.ora file
  2. start receiver < nom_recepteur >
  NOTE: This must be done via a shell script.
  
  
  Question:
  1. the solution above will make the listener authentication OS again?
  2 does the script below make sense?
  

  #! / bin/bash
  # Modify the listener to use only the OS authentication
  CD $HOME
  . . / mydb
  CD $ORACLE_HOME/network/admin
  CP listener.ora listener_'date of +%Y-%m-%m'.ora
  CP tnsnames.ora tnsnames_'date of +%Y-%m-%m'.ora
  Lsnrctl set of password $instanceName
  $instanceName lsnrctl stop
  SED EI "/ PASSWORDS_/d ' EI ' / SAVE_CONFIG_ON/d ' e ' / #-/ d ' listener_' day +%Y-%m-%m'.ora > listener.ora
  lsnrctl start $instanceName
  echo "Listener $instanceName update"
  echo "* mydb.sh is complete * '

  I'm more worried about 7th line, where the password is defined. I would appreciate any help with the password that passes to the listener via the script

  Yes, the listener returns to OS authentication if you remove the "PASSWORDS_MYDB =" line of listener.ora and then bounce the listener. You can check this by using a 'lisnrctl status' command before and after the rebound. "Judge of what happens to a test on one of my listeners, while the listener is password protected" lsncrtl status "should show the line

  Security                  ON: Password or Local OS Authentication
  

  After removing the listener.ora password and restart the listener, this should change to

  Security                  ON: Local OS Authentication

  1. check the lsnrctl services

  2 check the tnsping output:

  tnsping MYORACLE

  3. check the connectivity to the computer hosting your Oracle server to the port (I guess 1521):

  Telnet 1521

  4. in case you are not able to connect to the Oracle Server - I investigate it in several directions:

  -problem of network infrastructure

  -some process disturbing / virus on the server Oracle itself

  -firewall problem

  Good luck!

• After changing the port (1521 to 1525 in listener.ora and tnsnames.ora) OEM: the database is down

  Hello

  I'm installing Oracle Database 11 g 2 (11.2.0.4) on Oracle Linux 7.1.

  In short, what I'm trying to do now is changing the default port of 1521 to 1525.

  So I stopped the listener (lsnrctl stop) and then changed my listener.ora and tnsnames.ora:

  Listener.ora

  listener.ora # Network Configuration file: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora

  # Generated by Oracle configuration tools.

  LISTENER =

  (DESCRIPTION_LIST =

  (DESCRIPTION =

  (ADDRESS = (PROTOCOL = CIP)(KEY = EXTPROC1521))

  )

  (DESCRIPTION =

  (ADDRESS = (PROTOCOL = TCP (PORT = 1525))(HOST = localhost))

  )

  )

  ADR_BASE_LISTENER = / u01/app/oracle

  tnsnames.ora

  tnsnames.ora # Network Configuration file: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora

  # Generated by Oracle configuration tools.

  BI =

  (DESCRIPTION =

  (ADDRESS_LIST =

  (ADDRESS = (PROTOCOL = TCP (PORT = 1525))(HOST = localhost))

  )

  (CONNECT_DATA =

  (SERVER = DEDICATED)

  (SERVICE_NAME = bi)

  )

  )

  And then changed the local_listener:

  SQL > ALTER SYSTEM SET LOCAL_LISTENER = "(ADDRESS = (PROTOCOL = TCP)(HOST=localhost) (PORT = 1525))";

  SQL > ALTER the REGISTRY SYSTEM;

  Finally, I started the listener (lsnrctl start) again.

  Then I tried to connect using Oracle SQL Developer to the customer. The port of 1525 works perfectly well.

  The problem is, when I open the OEM (Oracle Enterprise Manager), it says: "the database is down. Please specify the credentials of the host to access the restart and database diagnostic tools," which is like this: http://imgur.com/oKLPW65

  So I logged on the account of the host, and it shows that the database instance, listener and the agent is all down like this: http://imgur.com/Bzr84bz

  It seems that the port used by the OEM is always 1521.

  What should I do? Can someone help me solve the problem?

  Thanks in advance.

  UPDATE:

  After changing the emoms.properties & the targets.xml (thanks to Elisabeth), you will need to reconfigure dbconsole using emca.

  So what I'm doing is decreasing the config:

  $ emca - deconfig dbcontrol db-rest drop

  and then create again:

  $ emca - create config dbcontrol db-rest

  Voila.

• Oracle on Windows Server R2 12.1.0 2012: cannot find listener.ora

  I installed Oracle12C on a Windows Server 2012R2

  I have configured the listener using oracle net configuration assistant

  the headset works fine.

  My problem is that I can't change my configuration of the listener

  -Setup Wizard net oracle do not allow me to change the existing configuration

  -I can't find the file listener.ora containing this configuration. I check here Oracle12\product\12.1.0\dbhome_1\NETWORK\ADMIN. The file isn't here. I run a global serach of evry server disk. There is no listener.ora file except in the sample folder.

  -lsnrctl shows the receiver works well, but it does not display the path of the listener.ora file

  So my question is:

  How can I change the configuration of the listener and where can I find the listener.ora file

  I just checked my installation 12 c on Linux and I do not have a listener.ora file in the directory $ORACLE_HOME/network/admin installation of the database. However, I listener.ora in the 12 c ASM Software House, which is the one that is active. As mentioned previously, a listener.ora is not necessary to start the process of listening with the default values. Databases are automatically register with the earpiece by default LISTENER. A listener, however, may be useful for remote connections to SYSDBA.

  FWIW, here's my listener.ora and sqlnet.ora files (you will need to change the host name).

• Listening port configuration Oracle reboot without touching listener.ora?

  Hello

  during the installation of a database in oracle restart the environment, right now I'm adding a listener to data through srvctl like this:

  srvctl add listener-l o LSNR_ ${Database} {ORACLE_HOME} Pei "TCP: ${PORT}".

  srvctl setenv listener -l LSNR_$ {Database} t ORACLE_BASE = ${ORACLE_BASE}

  In addition, I add the appropriate to the listener.ora corresponding lines: (example)

  LSNR_PLAY =

  (DESCRIPTION_LIST =

  (DESCRIPTION =

  (ADDRESS = (PROTOCOL = TCP (PORT = 8029))(HOST = sol001.hypoport.local))

  )

  )

  ADR_BASE_LSNR_PLAY = / ora01/app/oracle

  ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LSNR_PLAY = WE

  ADMIN_RESTRICTIONS_LSNR_PLAY = WE

  It works as well for a long time I I'm not touching any configuration of the listener. But when I'm trying to change some parameters of the listener, an oracle agent rewrites the listener.ora file on its own in order to reflect these changes.

  So I wonder if I can completely jump to touch the listener.ora on my own file and let this agent to this work, while all configurations with srvctl (or maybe lsnrctl). But it would take to activate / ADMIN_RESTRICTIONS way ENABLE_GLOBAL_DYNAMIC_ENDPOINT permanent using these utilities. Is this possible? How?

  
  

  THX
  

  Robert

  
  

  ==================================

  IG is 11.2.0.4

  DB is 11.2.0. [34]

  So, just adding

  ADMIN_RESTRICTIONS_ = WE

  to the listener.ora just. Everything needed is generated by an agent of the basic config with "srvctl add listener." Other "lsnrctl set" specific settings must be entered manually on the listener.ora if necessary.

  Thank you.

• location of the file tnsnames.ora and Listener.ora

  Hello

  env: Oracle 11 g 2 - Orable Linux 6.2 64bits

  I set up a database for the client server. I installed IM and the House according to the standards of the Oracle RDBMS. Then I configured the listener to run BOF IM home. If the location of the 'ora, tnsnames' and 'listener.ora' files is $GI_HOME/network/admin.

  Customer's DBA is asking me to conform to the standard for the location of these two files. Here's what he asked for:

  / opt/oracle/owner = oracle, group = s/n (755 permissions)

  / var/opt/oracle owner = oracle, group = s/n (755 permissions)

  • -touch /var/opt/oracle/listener.ora
  • -touch /var/opt/oracle/tnsnames.ora
  • -chown oracle: dba /var/opt/oracle/listener.ora
  • -chown oracle: dba /var/opt/oracle/tnsnames.ora
  • -s /var/opt/oracle/tnsnames.ora /etc/tnsnames.ora ln
  • -s /var/opt/oracle/listener.ora /etc/listener.ora ln

  I'm completely lost here. I don't know if I'm moving these two files in the folder "/ etc", how the LISTENER know about the presence of these files in ' / etc '.

  His reason for this is to support the possibility of having several houses of Oracle's RDBMS. I don't know what he's talking about.

  Please notify.

  Best regards

  Thanks to you two!

  So basically this DBA do not like to follow standards of Oracle but his own.

  BINGO!

  What is the problem with the help of $ORACLE_HOME/network/admin for these two files if there were several homes of oracle on a server? Sorry I never got to work on a server with multiple oracle homes, so I have no idea.

  The 'standard' with several houses installation is to run the listener from the version the most recent House.  If all of the houses are of the same version (putting aside the question of 'why'), then just pick one that is going to be home for the listener.  If the installation program uses the Grid Infrastructure (ASM and/or Oracle Restart), you must run the listener from the House of IM, not House the database.

  There are some key things to consider here.

  1. the auditor is to receive and process applications for connecting customers.  This is why the listener has no meaning on the Server.  Similarly, its configuration file, listener.ora, only makes sense on the server.

  1a. a single listener, using the default name of the LISTENER and the unique default port of 1521 is quite capable of--indeed, we wanted to - several multiple databases editions of multiple service homes.

  2. the tnsnames.ora file provides a name resolution and address customers.  So it has the sense that on the client computer.

  2. when a database uses a db link to access a different database, the first database acts as a client to the second - as with any other LDAP client.

  Thank you

  I meet emca error before and it is just resolved when I created lisnter.ora, so I want to try it.

  I doubt that listener.ora was the cause.

  Although experience is a better teacher.

  No, trying to find the cause of a problem is a better teacher, just try things at random - it's a good way to teach you things like "emctl start dbconsole does not work without a listener.ora", which is clearly false.

  Once start emca

  The command is not 'emca,' maybe that's your problem.

  We don't know, because you have not copied/pasted something here, including the error message
