confusions tnsnames.ora
Hi all
11.2.0.3
We have the listener.ora on our prod server.
Listener.ora
========
PROD =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = prodsvr) (PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = PROD)
)
)
LISTENER_SVR =
(ADDRESS = (PROTOCOL = TCP)(HOST = prodsvr) (PORT = 1521))
=========
My question is, what is the usefulness of the LISTENER_SVR line? If I delete it, my tnsnames still works. Is it useless at all?
Thank you
pK
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.

Need PMON use tnsnames.ora to find no-DEFAULT listener?
Hello
I just want to confirm that because it is said tnsnames.ora used only for the customer. So I'm a bit confused by this use.
Please give some explanations about this.
Thanks in advance.

MartinI know from experience as well - when I put in place LOCAL_LISTENER and REMOTE_LISTENER in 9iRAC.
It is quite simple in 11.2 documentation:
http://download.Oracle.com/docs/CD/E11882_01/server.112/e17110/initparams116.htm#i1128493
«+ LOCAL_LISTENER specifies a network name that resolves to an address or a list of addresses of Oracle Net local listeners (i.e. listeners who are running on the same computer as this instance).» The address or the address list is specified in the TNSNAMES file. ORA file or another trustee address configured for your system. » +
http://download.Oracle.com/docs/CD/E11882_01/server.112/e17110/initparams206.htm#i1132970
"+ REMOTE_LISTENER specifies a network name that resolves to an address or a list of addresses of listeners distance Oracle Net (i.e. the listeners that are not running on the same machine as this instance). The address or the address list is specified in the TNSNAMES file. "ORA file or another trustee address configured for your system.
I believe that earlier versions of the document indicate clearly that the 'address or address list of Oracle Net remote listeners' carried out since the tnsnames.ora. There was a few messages from forums on this confusion over the years.

A listener.ora on the client makes as much sense as a radiator on a 1965 Volkswagen. The listener is strictly a process on the server side. That's the whole reason to live is to 'listen' (where its name) for connection requests.

*)*OK, let's clear up a few things.
First of all, as mentioned, the listener is purely a process on the client side. There is therefore no use to a listener.ora on the client.
Second, a single listener, listening on a single port, can serve several databases multiple editions in multiple oracle homes. He listens to a connection, it puts in place (on a different listening port on) and then is out of the picture for this connection. It establishes the connection, but not the support it. Your listener.ora is much more complex (dare I say convoluted) as necessary.
On the client side (the server can also act as a client) and the tnsnames.ora is used to resolve an alias (a tns service name) to a real destination on the network.
Suppose you have the following in your tnsnames.ora:
larry = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = myhost)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = curley) ) )
Now, when you issue a connect, say like this:
$> sqlplus scott/tiger@larry
TNS will appear in your tnsnames.ora for an entry called "larry". Then, tns sends a request to (PORT = 1521) on (HOST = myhost) to aid (PROTOCOL = TCP), requesting a connection to (SERVICE_NAME = curley).
Where's (HOST = myhost) on the network? When the request is passed to tns to the next layer in the network stack, the name "myhost" resolves to an IP address, either via a file 'hosts' local, through DNS, or possibly other mechanisms being used less. Alternatively, you can hard-code the IP (HOST = 123.456.789.101) in the tnsnames.ora.
Then, the request arrives (port = 1521) on (HOST = myhost). If all goes well, there is a listener on myhost configured to listen on (PORT = 1521), and this listener knows (SERVICE_NAME = curley). If so, you'll be connected.
What can go wrong?
First, there may not be an entry for 'larry' in your tnsnames file. In this case, you get "ORA-12154: TNS: could not resolve the connect identifier specified" no need to go looking for a problem on the host, with the listener, etc.. If you cannot place a phone call because you do not know the number (can't phone your telephone book or can't find the group you're looking for it contained therein) you don't look at problems at the switchboard.
Perhaps the entry for larry was found, but myhost could not be resolved to an IP address (for example there is no entry for myhost in the local hosts file). This will mean by "ORA-12545: Connect failed because target host or object does not exist.
Maybe there is an entry for MyServer in the local hosts file, but it specified a bad IP address. This will mean by "ORA-12545: Connect failed because target host or object does not exist.
Maybe the INVESTIGATION period was good, but there is no listener running: "ORA-12541: TNS:no listener.
Maybe the INVESTIGATION period was good, there is a listener to myhost, but he is listening on a different port. "ORA-12560: TNS:protocol adapter error.
Maybe the INVESTIGATION period was good, there is a listener to myhost, listening on the specified port, it's unknown SERVICE_NAME = curley. "ORA-12514: TNS:listener is not currently of service requested in connect descriptor.

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.

DBD::Oracle and instant client - can't find tnsnames.ora
Hi all! :-)
Guys, please, help!
My OS: CentOS 6.6, i386
Installed:

Perl-DBI-1, 609 - 4.el6.i686
and last perl-DBD-Oracle-1, 74-CPAN.
Apache 2.2.15, mod_perl 2.0.4
SELinux disabled.
ORACLE_HOME = usr/lib/oracle/12.1/client, LD_LIBRARY_PATH = /usr/lib/oracle/12.1/client/lib
tnsnames.ora exist in /usr/lib/oracle/12.1/client/network/admin
I wrote a simple perl script to test the connection:
use strict; use DBI; 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) || die "Failed to connect: $DBI::errstr\n";

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.
Best regards
user130038 wrote:
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.
Best regards

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.
For more information on the above view, see:

Hi all
11.2.0.1
AIX 6.1
We have databases DEV & UAT residing on SERVER1.
Each has its own listener namely: listener_dev (1523) & listener_uat (1522)

and

Then I copied the tnsnames.ora for each and merge on tnsnames.ora my laptop
Then, on the command-line to my laptop, I run:

Hello
To test if the firewall is open:
go to back
Telnet 10.2.9.6 1523
If it just hangs firewall is part of the way, if you get a connection, then it is open.
If you trace the route to the server from the client is a simple path? you have a firewall on your laptop? the server itself or a network firewall in between?
Kind regards

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)
NAMES. DEFAULT_DOMAIN = mydomain.com
My TNSNAMES file. ORA file is as follows on both servers:
WLDB_HERE =

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)
NAMES. DEFAULT_DOMAIN = mydomain.com
My TNSNAMES file. ORA file is as follows on both servers:
WLDB_HERE =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = primary_server) (PORT = 1521))
)
(CONNECT_DATA = (SERVICE_NAME = wldb_here.mydomain.com))
)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.
You do not have an entry in your tnsnames.ora to 'WLDB_HERE.mydomain.com '.
WLDB_THERE =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = standby_server) (PORT = 1521))
)
(CONNECT_DATA = (SERVICE_NAME = wldb_there.mydomain.com))
)I have a static entry in the remote listener.ora file so I can connect to create the instance:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = wldb_there.mydomain.com)
(ORACLE_HOME = / u01/app/oracle/product/OraHome112)
(SID_NAME = WJZI)
)

Change the location TNSNAMES.ora (discoverer 11g)
HelloI 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
Best wishes

connect sqlplus without tnsnames.ora
Hello
I have nothing in tnsnames.ora locally.
I don't have a local instance of the DB, I always have to connect to an instance on a server. How can I connect using sqlplus?
The result is ORA-12514!sqlplus [email protected]:1521/MYSID
connect without tnsnames.ora. For example:
sqlplus scott/tiger @(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(Host=server_a) (Port = 1521)) (CONNECT_DATA = (SID = db_a)))

OID server to replace TNSNAMES.ora
Can someone please provide step by step documentation how to use Server OID o replace tnsnames.ora?
In addition, please provide installation step by step 11g and 10g and set up guide? I'd really appreciate who.Configuration and installation of OID/LDAP involves multiple groups of Oracle Support
and requires a Request (SR) of separate Service for these areas of support. To respond to your
General Advisory issues, I recommend your review the following notes of My Oracle Support.
These articles provide general information as an alternative option for the use of adapters OID/LDAP
and a central depot to replace the TNSNAMES file. Once you launch the installation of the OID/LDAP and
and the Setup process, you can address specific questions with the respective support group.References:

Ifile in tnsnames.ora/listener.ora
Hello
I find IFILE entered my listener.ora of applications and tnsnames.ora oracle database.
What is the use of IFILE? I hear that the entries in IFILE are not overnwritten using autoconfig. Is this true?
We create the tnsentries of other databses in ifile.
Someone could give advice.
tnsnames.ora
============
IFile=/Gold/App/DB/11.2.0/Network/admin/gold_srvr315/gold_srvr315_ifile.ora
Listener.ora
=============
IFile=/Gold/App/DB/11.2.0/Network/admin/gold_srvr315/listener_ifile.ora
Thank youI find IFILE entered my listener.ora of applications and tnsnames.ora oracle database.
What is the use of IFILE? I hear that the entries in IFILE are not overnwritten using autoconfig. Is this true?
Correct, and it is the use of the IFILE (i.e. create entries that must be preserved and not affected or overwritten by the automatic configuration service.
