• ORA-12170: TNS: Connect timeout occurred on the same host as DB

  Hello

  I just installed Oracle on mu Ubuntu 12.4 following the instructions here:

  http://www.Makina-corpus.org/blog/HOWTO-install-Oracle-11g-Ubuntu-Linux-1204-precise-pangolin-64bits

  and here:

  Install Oracle 11 GR 2 on Ubuntu 12.04 of the databases

  However, when I try to log on to the database, I created during installation using sqlplus, it hangs for a minute or two until it-error:

  ORA-12170: TNS: Connect timeout occurred.

  My tnsnames.ora:

  MYSIS =
  (DESCRIPTION =
  (ADDRESS = (PROTOCOL = TCP)(HOST = my_host) (PORT = 1521))
  (CONNECT_DATA =
  (SERVER = DEDICATED)
  (SERVICE_NAME = mysids)
  )
  )

  I checked that the listener is running and listening to the post 1521:

  s$ sudo netstat - tulpn | grep 1521

  tcp6 0 0: 1521: * LISTEN 16732/tnslsnr

  $ ps - ef | grep 16732

  Thoughts?

  Finally managed to do run. The problem was that I have not read rights to tnsnames.ora.

• manage the runtime error 1000: server lost connection/file not found

  I have a videoDisplay object that throws an error file not found on the server running, even if it is there. Sometimes it works, sometimes it throws the error and the program cannot recover from the error, so after that the error is thrown, the object is stuck until the refill. I've seen examples of using the NetStream class to load the file before playing and also the class NetConnection.
  
  What is your preferred method for the two video load, assuming that the user will change the video source several times during the session and management research of server errors?

  Yes, you'd know that if you're using FMS.
  If you use a var can be linked to the source of the string, this is the first place I'd watch. You can try a stripped down from the sample application with no link? Just change the source of a button click and see if the server generates the error... I bet it won't

  When everything has failed, read the Fine Documentation

  http://www.Oracle.com/technetwork/database/features/OCI/IC-FAQ-094177.html

  "How can I specify the connection in Instant Client mode strings?
  All methods NET naming Oracle does not require the use of ORACLE_HOME or TNS_ADMIN (to locate the configuration such as tnsnames.ora or sqlnet.ora files) work in Instant Client mode. In particular, the connection string can be specified in the following formats:

  A SQL Connect URL string in the form:

  Host: [port] [service name]

  such as:

  dBase-Server - 5:4321 / ORDERS

  As a pair of keyword / value Oracle Net. For example:

  "(DESCRIPTION = (ADDRESS = (PROTOCOL = tcp) (HOST = dlsun242)
  (PORT = 5521))
  (CONNECT_DATA = (SERVICE_NAME = bjava21))) »

  Naming methods that require TNS_ADMIN locate configuration files continue to work if the value of the TNS_ADMIN environment variable.

  If the TNS_ADMIN environment variable is not defined and TNSNAMES entries for example, inst1, are used, the variable ORACLE_HOME must be set, and the configuration files are supposed to be located in the directory of $ORACLE_HOME/network/admin.

  Please note that the ORACLE_HOME variable in this case is only used to locate the Oracle Net configuration files, and any other component of Client Code Library (OCI, NLS and so forth) don't use the value of ORACLE_HOME.

  The adapter unreserved or empty connection strings are not supported. However, another way to use the empty connection string must affect on UNIX TWO_TASK environment variable, or the LOCAL Windows variable, a tnsnames.ora entry or a pair of keyword / value Oracle Net. If LOCAL or TWO_TASK is set to a tnsnames.ora entry, then the tnsnames.ora file must be loaded by setting ORACLE_HOME or TNS_ADMIN.

  Try to edit listener.ora by:

  Just try to edit HOST = value line above. You must use HOST_NAME_OF_YOUR_DATABASE_MACHINE or IP OF the DATABASE SERVER MACHINE.

  Host name can be obtained by the hostname command on the database server.

  With localhost, no one can connect to the database remotely.

  Hello

  [oracle@myoramachine ~]$ oerr ora 12505
  12505, 00000, "TNS:listener does not currently know of SID given in connect descriptor"
  // *Cause:  The listener received a request to establish a connection to a
  // database or other service. The connect descriptor received by the listener
  // specified a SID for an instance (usually a database instance) that either
  // has not yet dynamically registered with the listener or has not been
  // statically configured for the listener. This may be a temporary condition
  // such as after the listener has started, but before the database instance
  // has registered with the listener.
  // *Action:
  //  - Wait a moment and try to connect a second time.
  //  - Check which instances are currently known by the listener by executing:
  //    lsnrctl services 
  //  - Check that the SID parameter in the connect descriptor specifies
  //    an instance known by the listener.
  //  - Check for an event in the listener.log file.
  [oracle@myoramachine ~]$
  

  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!

  When I posted my first response, I guess you are trying to connect to your database that is running on the same server, i.e. locally. So I wanted to make sure DOB connections are ok. But appearantly not. You get the ORA-12560 error when "/ as sysdba".

  To do so below if my hypothesis is correct:

  1. go to the command prompt
  2. set the ORACLE_HOME =
  3. set ORACLE_SID =
  4. set the path ="/ bin"
  5 sqlplus "/ as sysdba".
  If it works, output
  6. now try sqlplus .

  Paste the result.

• ERROR - ORA-12514: TNS:listener does not know now of immediate service

  Hi all
  Is the problem that I do face when I access oracle 10g database.it was wrking fine a few days back then I installed the developer 10g suite.after I am facing the problem (ERROR - ORA-12514: TNS:listener does not know currently of service requested in connect descriptor) every time I try and access my database.any 10 g help will be very appreciated.
  Thanks in advance
  Mourad

  Hello

  Make sure that you use right tnsnames.ora as you have it installled oracle developer suite after installation of the database so it could change your ORACLE_HOME as a result of developer. You have 2 choices

  1. replace oracle_home installation of oracle database in the variables env control panel system
  or
  1 copy the tnsnames.ora, listener.ora under Developer suite... location/networ/admin.

  If you are using on your local computer, you do not have this and you should be able to connect but if you use it is not bad either.

  Output from the following command post

  lsnrctl status
  

  Concerning

• When I try to connect from the client to the RAC by using the SCANNER, I get ERROR: ORA-12541: TNS: no listenerOracle

  CARS: 2 nodes with Oracle single Client Access name (SCAN)

  OS: OEL 5.4 64-bit

  Version: 11.2.0.3

  When I try to connect from the client to the RAC by using the SCANNER, I get ERROR: ORA-12541: TNS: no listenerOracle. I noticed that the service is in place and properly configured (client tnsnames).

  servicioBD = (DESCRIPTION = (LOAD_BALANCE = yes) (ADDRESS = (PROTOCOL = TCP)(HOST = scanvip.domain1.local) (PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = serviceBD) (FAILOVER_MODE = (TYPE = SΘLECTIONNER) (METHOD = BASIC) (RETRIES = 180) (DELAY = 5))))

  serviceBD service

  serviceBD BASIC SELECT 180 NO LONG YES

  But when I do not use the service created for the tnsnames file SCAN, it's that if I directly put tnsnames to connect to any work of two nodes very well.

  Node 1

  servicioBD =

  (DESCRIPTION =

  Or

  I have also observed the following (cluvfy).

• DB Link error: ORA-12154: TNS: could not resolve the connect identifier specified

  Hi all

  We need to make an entry in the tnsname.ora file in a local database to connect to the remote database using db link?

  Here is my code: -.

  create the database link * _DBLINK

  connect to the USER IDENTIFIED BY 'user '.

  using '(DESCRIPTION =)

  (ADDRESS_LIST =

  (ADDRESS = (PROTOCOL = TCP) (HOST = *. *. *. *)(PORT = 1521))

  )

  (CONNECT_DATA = (SERVICE_NAME = REM)

  )';

  After the creation of the DB connection when I'm trying to run select 1 of dual@***_DBLINK

  He throws me an error ORA-12154: TNS: could not resolve the connect identifier specified

  Am I expected to do an entry in the file tnsname.ora for "REM". I don't remember making any changes in the file tnsname.ora for the creation and access of the remote database via dblink.

  Help, please.

  Thanks in advance.

  I've learned to trust in your obfuscation you covered something important, or you are showing some apples and oranges.  Error to declare you come from not being able to find referenced in tnsnames.ora entry, but the way you say you created your link db, you hardcoded the entire connection, so he never users tnsnames.ora.

  I would change the definition of db_link

  create the database link * _DBLINK

  connect to the USER IDENTIFIED BY 'user '.

  using "REM."

  Then create an entry in your tnsnames.ora

  REM =

  (DESCRIPTION =

  (ADDRESS_LIST =

  (ADDRESS = (PROTOCOL = TCP) (HOST = *. *. *. *)(PORT = 1521))

  )

  (CONNECT_DATA = (SERVICE_NAME = REM)

  )

  )

  Also, use server name instead of the HOST = IP address

  The closer looks that you can miss brackets final closing on your original definition.
