Irregular deadlines in tnsnames.ora

• 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.

  my $dbh = DBI ->connect("dbi:Oracle:crm", 'login', 'password',{RaiseError => 1} );
  $dbh->disconnect();
  
  

  When I try to run script command line - everything isn't ok, no errors (Yes, I can run queries, etc... )

  But!

  With apache, I get an error:

  DBI connect('crm','login',...) failed: ORA-12154: TNS: could not resolve the connect identifier specified (DBD ERROR: OCIServerAttach) in /opt/otrs/bin/cgi-bin/oratest.pl on line 9

  I am trying to add ORACLE_HOME with PerlSetEnv and script see (I checked through % ENV), but no luck.

  Probably easier to use EZconnect instead of tnsnames.ora:

  $machine = 'my.oracle.database.com';
   $port = 1521;
   $sid = 'my_sid';
   $dbh = DBI->connect("dbi:Oracle://$machine:$port/$sid", $user, $pass) ||

  Question is, why would you type this value in the tnsnames.ora? And you must confirm that after stop and restart listener, it's still operational or not. If this is the case, you don't need this entry.

• Links to DB, auditor and 2 tnsnames.ora

  Hello

  I would like to have some information about the following situation:

  I installed on server1 Oracle 11.2 in the patches dbhome1 Group 3 (first place) and in the Group of hotfixes dbhome2 4 (Group of patches).

  Now, the listener is always that of the patches dbhome1 Group 3 (where the tnsnames.ora y/network/admin).

  I instance1 created with dbca patches dbhome2 Group 4. Instance1 has a link to db dblink1 to server2.

  Now the strange thing, dblink1 cannot connect to the host.

  The tnsnames.ora in dbhome1 contains the correct entry (tnsping with variables env dbhome1 works flawlessly). But if I do a tnsping with dbhome2 env variables, then it does not work (in fact the tnsnames.ora to dbhome2 has a WRONG server name in the entry). After I corrected the tnsnames.ora to dbhome2, all was FINE.

  My question, I guess the listener takes the tnsnames.ora to dbhome1, why a dblink to an instance of dbhome2 not use this file, but rather the tnsnames.ora to dbhome2 (the listener runs on dbhome1)? A feedback?

  Thank you

  Martin

  The listener has nothing to do with the tnsnames.ora. The important thing is the value of the TNS_ADMIN environment variable except that the value of ORACLE_HOME for the process in question. If TNS_ADMIN is undefined, instances that are running 2 House will pick up the tnsnames of House 2.

• 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.

  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.

• Is it possible to query the TNSNames.ora OEM repository info?

  Hello

  My project requires me to generate the OEM repository TNSNames.ora.

  Is this possible? Does anyone know how interrogate this OEM repository.

  I would need to HOST, PORT, and SID to generate the file in the format requested.

  Thank you

  Mihir

  Mihir,

  You can query the view of MGMT$ TARGET_PROPERTIES for the information.

  Ex:

  Select property_name, name

  Mgmt $ target_properties

  where target_name = "."

  and property_name in ('ComputerName', 'Port', 'SID', 'PreferredConnectString');

  Note: If a value (connection string) is set to "PreferredConnectString" as the connection string will be used.

• Net Oracle does not read the tnsnames.ora file.

  I am running 11.2.0.3 on Solaris 10 SPARC x 64. I'm trying to configure oracle net for a new database on hold in order to be able to use rman duplicate to create. LDAP is what we mainly use for all of our connections and, possibly, what I could use very well for my goal of rman duplication. But, I fear that I do nothing seems to allow me to read the tnsnames.ora file.

  My SQLNET. ORA file is as follows:

  NAMES. DIRECTORY_PATH = (LDAP, TNSNAMES)

  Because you have NAMES. DEFAULT_DOMAIN = mydomain.com in your sqlnet.ora, when you try to connect to "WLDB_HERE", before tnsnames.ora is read, sqlnet will transform your application in "WLDB_HERE.mydomain.com".  And that's what he's going to get.

• Change the location TNSNAMES.ora (discoverer 11g)

  
  Hello

  I have a requirement where I need to change the location of tnsname.ora.

  I installed Oracle Fusion Middleware install (11.1.1.7) and then set the field to the Finder only.

  Tnsnames.ora location is $DISCO_INST_HOME/config/tnsnames.ora

  Another use of symbolic link, can I change the configuration to change the location of the TNSNAMES.ora file.

  Concerning

  Sumit SALAUN

  Hi Sumit

  I have additional information for you, with the permission of a contact I within the Oracle.

  Yes, you can use the TNS_ADMIN environment variable.

  Indeed, in the [middleware_home]\[oracle_instance]\config\OPMN\opmn\opmn.xml that it points to the location that you mentioned.

  You can update the location of the file

  Run: [middleware_home]-[oracle_instance\bin\opmnctl reload (to pick up the new changes in the opmn.xml file

  the next session of discoverer (dis51ws) began to read the changes.

  If this fails, stopall opmnctl, then opmnctl startall

  I also checked on other files that I mentioned earlier. We believe that they are not necessary for the discoverer, or why they would have this environment variable defined here as the repositories of metadata of Fusion Middleware use JDBC. They must be to another generic use of Weblogic or custom java applications.

  The binary discoverer/server only read /sessions opmn.xml - so simply by changing opmn.xml should be enough

• EM does not create entry tnsnames.ora with service name orcl11gr2

  Hi all
  
  I am trying to create a service network with EM Database Control, Net Services Administration link name. On the service name field, under the "Edit Net Service Name" screen, I type in orcl11gr2, and it throws the following error:
  
  Validation error
  Review and correct the following errors, and then try again:
  Service name - specify a valid service name.
  
  I wonder what is the additional validation that checks EM. I guess it's to check the number of characters to 8 characters or less.
  
  In addition, because of this additional validation that is in MS, all entry tnsnames.ora with service name = orcl11gr2, I won't be able to use 'EM to change, as I have the same error.
  
  But why Oracle implements this additional validation when the same validation is not implemented on other Oracle tools? For example:
  1 dbca allows me to create a database with instance_name greater than 8 characters, and the results of the initialization parameters will be as follows:
  db_name = orcl11gr - truncated to 8 characters
  instance_name = orcl11gr2
  db_unique_name = orcl11gr2
  noms_service = orcl11gr2
  
  2 oracle Net Manager supports the name of orcl11gr2. The name of the created Service Net, I have no problem connecting to the database.
  3. name of the service orcl11gr2 of listener support

• Creating a service; What must be included in tnsnames.ora and JDBC url?
