Setup multiple server... what plsql... what tnsname.ora?

I have several copies of the installed Oracle software (multiple ORACLE_BASE and each one has several software database installed).

When I type SQLPLUS, one of them starts.

In Windows, I know, it depends on the PATH variable. How do I know what SQLPLUS. EXE is launched?

Also, what TNSNAMES file. ORA file is used for a connection to SQLPlus?

Oracle 10g R2.

Thank you
Smith

You can determine what tnsnames.ora is getting used by setting the OS TNS_ADMIN environment variable to the directory where your tnsnames.ora preferred listener.ora etc. is located.

  • customer will not use the correct tnsnames.ora file

    Hello all, I installed oracle 10g client on my machine... but here's the thing... I tnsnames.ora several file on my machine (which I can't delete or play with)... and because of this oracle is not able to connect to the database I want it to connect to... I can't do tnsping to the database... is there a way where I can point my client to use a specific tnsnames.ora file? as a pointer? or something where it will look in this file specific tnsnsame.ora?

    You can specify what tnsnames.ora for use the TNS_ADMIN environment variable
    Switch to the directory that contains your tnsnames.ora to use.

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

    DB version: 11.2.0.2
    Operating system platform: Solaris 10

    We have a 2 RAC node.
    DB name   = mbsprd
Instance1  = mbsprd1
Instance2  = mbsprd2
    I want 1 Instance (mbsprd1) to use for our OLTP and Instance 2 (mbsprd2) application to use for another nature DSS request.

    According to the syntax
    srvctl add service -d <dbname> -s <ServiceName> -r <Preferred Instance> -a <Available Instance>
    I create 2 services

    -Creation of a service called OLTP
    srvctl add service -d mbsprd -s OLTP  -r mbsprd1 -a mbsprd2
    -Creation of a service called DSS
    srvctl add service -d mbsprd -s DSS  -r mbsprd2 -a mbsprd1
    -Start services
    srvctl start service -d mbsprd -s OLTP

srvctl start service -d mbsprd -s DSS
    I guess the above steps are sufficient to set up a service on the side server.

  • What configuration must define in tnsnames.ora

    Dear all,

    Need your help. I have zero knowledge in oracle. Now, I need to conenct to the Oracle database from my window via SQLPlus server, which configuration should I set in my tnsnames.ora? A or B?

    Set A
    PNTP =
    (DESCRIPTION =
    (LOAD_BALANCE = on)
    (FAILOVER = on)
    (ADDRESS_LIST =
    (SOURCE_ROUTE = yes)

    How can i make sure the pointer are D:\oracle\ora92\network\ADMIN and not another folder? Can check from "environment variables "? WHich part?

    I suggest you go back to the documentation and reading.
    Please look at the following:

    http://download.oracle.com/docs/cd/B19306_01/install.102/b14312/post_install.htm#CHDBIHEE

Then, on each client computer, configure either of the following settings:

    *

      Set the TNS_ADMIN environment variable to specify the location of the tnsnames.ora file and specify a service name from that file.
    *

      Place the tnsnames.ora file in the ORACLE_BASE\ORACLE_HOME\network\admin directory, and make sure that the ORACLE_HOME environment has been set to this Oracle home.

    Your tnsnames.ora file should contain the following, assuming that you have (n) number of nodes:

    PNTP =
(DESCRIPTION =
(LOAD_BALANCE = on)
(ADDRESS_LIST=
(ADDRESS = (PROTOCOL = TCP)(HOST = Hostname1-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = Hostname2-vip)(PORT = 1521))
.
.
.
(ADDRESS = (PROTOCOL = TCP)(HOST = Hostname(n)-vip)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = pntp)
)
)

  • What TNSNAMES?

    Hi all

    on the 11g R2, we have three files in D:\oracle\product\11.2.0.4_64b\client_1\network\admin:

    We can define a file under a different name than tnsnames.ora tnsnames serve? How?

    Thank you.

    I have been working with Oracle for v7.3 and have written extensively on the AMT configuration, and I don't know any way to tell oracle to use one file other than simply "tnsnames.ora.  You can control WHERE he's looking for the file, but not the name of the file.  If someone can prove me wrong, I'd be more than happy to learn otherwise.

    If your question is 'why do we have other files' I must say that you have to ask the guy who put them there.  They are certainly not creating oracle.

  • 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

  • When I need the machine tnsnames.ora and customer configurations?

    Hello

    I installed Oracle 11 g on Linux system and successfully created the databases. I can access the database (on server) Enterprise Manager and SQL * (by sqlplus SYSTEM/pass@ora). On another computer I installed the Oracle 11 g database Client (and chose the type administrator installation). Before you start the network for local configuration Setup Wizard Net Service Name, I started Enterprise Manager (the same address, what happens on the server). I was very surprised that I can access Enterprise Manager client without any additional configuration.
    I know, tnsnames.ora help with SQL * more (we can access SYSTEM/pass@ora and don't give no address ip and port).
    And my questions: can I access by Enterprise Manager of any client computer without creating tnsnames.ora and additional configurations client machine?
    Is SQL * more use only tnsnames.ora?

    Thanks awfully for help.

    Yes, because the Business Manager is an application of 3 layers: you connect to an application server that connects to the database instance.

    Luk004 wrote:

    No.: each client must connect directly to the instance of database with a base layer Oracle Call Interface (OCI) must use tnsnames.ora.
    There are a few exceptions:

    customer listener.ora (orcl)

    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.

    Customer tnsnames.ora

    LISTENER_TEST1 =
    * (ADDRESS = (PROTOCOL = TCP) (HOST = Desktop029.tvsil.com)(PORT = 1521)) *.

    *(DESCRIPTION =*)
    * (ADDRESS = (PROTOCOL = TCP) (HOST = Desktop029.tvsil.com)(PORT = 1521)) *.
    *(CONNECT_DATA =*)

    (* (ADDRESS = (PROTOCOL = TCP)(HOST = desktop041.tvsil.com) (PORT = 1522))) *.

    * (SID = PLSExtProc) *.
    * (PRESENTATION = RO) *.
    *)*
    *)*

    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.

  • 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.

    Best regards

    Jerry Antonius

    Hello

    Try to change the port numbers in the following files

    Don't port no 1521 to 1525

    $ORACLE_HOME /_SID/sysman/config/emoms.properties

    oracle.sysman.eml.mntr.emdRepPort = 1525 (before 1521)

    $ORACLE_HOME /_SID/sysman/emd/targets.xml

    (Before 1521)

    (Before 1521)

  • confusions tnsnames.ora

    Hi all

    11.2.0.3

    We have the listener.ora on our prod server.

    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.

  • 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.

  • tnsnames.ora and oracle cleint

    We have a duty to make an analysis of data on one of our oracle databases. We have a copy of the tnsnames.ora file with the Server DB and SID etc.

    If you use something like toad or gold to query the DB, you also need to install client oracle on the machine (windows XP)? Or just the TOAD software?

    Is there a device by default on XP where tnsnames.ora needs to be saved?

    And if we don't need the customer what is the right version?

    Toad, Yes, you have the Oracle client. Cannot say on 'gold', I don't know what it is. In general, any product like that will sit on top the Oracle client, not replace it.

    There is nothing magical about tnsnames.ora. It is just a file of name resolution that is used by the software oracle client. If you have a magical application which replaces the customer oracle instead of using it, then your tnsnames.ora will be without intrinsic value beyond giving you the necessary information configure magic of the application.
