  Hello

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

  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:

  My tnsnames.ora:

  (CONNECT_DATA =

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

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

• managing the Oracle ERROR ORA-12170: TNS: Connect timeout occurred

  Hello all dear
  
  We have a server that is responsible for collecting data from some customers. In each of these devices, we have installed Oracle 11.2 g and that they are connected via DB-link. There is a stored procedure that test the connection before doing this either by running the command (+ select count (*) of dual@db_link1+). In the situations that one of the clients is not accessible, this ORA-12170 error occurred and there will be an end to MS. Now, I want to avoid this and want to sp jump this client and connect to another. I wonder if there is an exception that is raised by this fatal error and we can do it.
  
  Thank you

  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.

• Stop the connection timeouts occur - want the page wait

  I run several tab that monitor various tools. These pages will refresh. Pages must wait each other finish before you can start.

  In version 28 it was beautiful. The page just wait indefinitely and kicked in a previous page after doing its thing.

  Now in version 29 he comes back with a message "connection timed out" after a few minutes.

  I adjusted

  Network.http.connection - timeout
  Network.http.pipelining.Read - timeout

  for values but the problem still occurs. Any thoughts on how I can find the FF28 behavior?

  Try setting the http.response.timeout parameter. In the version 28, it had not been established. Version 29, it is located at 300 (5 minutes). Should help to move on to something much larger.

  See this blog entry:

  When I ask them to TNSPing or when accessing from Sql Plus(instant client), this is the mistake they receive:

  One of the developers using Oracle XE and it is too face the same scenario.
  
  So, where should I trace this problem.

  Is there a way to check via Oracle if the firewall blocks?

  Check the file sqlnet.log for more information.

  What is your OS?, if windows check in the control panel---> windows firewall

  Hello
  
  The scenario is this: I have Oracle 11 g R2 installed on a server to Windows Server 2008 (32-bit). The database SID is "PGM". I am access (or want to access remotely to) the Oracle database in Visual Studio 2008 (customer environment) development environment running on a Windows XP (SP3) platform. I have already installed the package of the ODAC (ver. 11.2.0.2.1) for the Visual Studio environment.
  
  I created a sample Windows Forms application that uses the Oracle data access components. The example of HR schema in the Oracle database is already unlocked. This is the pattern that I use in the application.
  
  The issue that I am facing is that when I add the data connection in the Visual Studio environment. Feature "Test connection" returns the following error: ORA-12170 ... Connection has expired.
  
  I checked the TNSNAMES file. File of the ORA and everything is as listed in the Oracle documentation. It's as follows:
  
  PGM =

• ORA-12518: TNS:listener could not hand off client connection

  Hello

  I'm getting "ORA-12518: TNS:listener could not hand off client connection" error trying to connect to the "PDB". Here are the details of my env and I do:

  Windows 7

  My PC to install Oracle 11 g 2 Client (that's how I got this PC). And I already 11 GR 2 installed Oracle software and a local database that is named "ORCL" (whichdesignates currently the stop).

  Yesterday, I installed Oracle 12 c (12.1.0) and created ORCL12C (CBD) and a PDBORCL (PDB). I connected to the PDBORCL as SYS and created user 'SCOTT '.

  I am able to connect to ORCL12C (PEH) without any problem (SQL * more and TOAD). I can go to PDBORCL (alter session set container = pdborcl) without problem. But I get the error above (ora-12518 am) when I try to connect to the user 'SCOTT' created in 'PDBORCL' using SQL * more or TOAD. I want to connect to the user SCOTT and create objects in schema SCOTT, etc.. I get the same error, even if I try to connect to the PDB as user SYS (alter session command works fine).

  I am new to 12 C. So it is quite possible that I'm doing something fundamentally wrong.

  Hello

  I think you are the problem of configuring the following listener results:

  >

  1. (SID_DESC =
  2. (GLOBAL_DBNAME = PDBORCL)
  3. (SID_NAME = PDBORCL)
  4. (ORACLE_HOME = u01/app/oracle/product/12.1.0/dbhome_1)
  5. )
  6. )

  >

  as you can see, you have defined an entry static listener for SID PDBORCL. If I read your message correctly, you are CDB Instance SID is ORCL12C and you're PDB is PDBORCL.

  So, in my opinion, as part of the configuration is the problem. PDB is saved as a dynamic Service to the Instance that you added

  an entry static listener for a non-existent Instance. And so you're static listener overlaying the APB Service dynamic PDBORCL configuration.

  and that is why it does not work.

  Look at the output of a registerd APB to a listener success:

  lsnrctl status

  ...

  Summary of services...

  Service '+ ASM' a 1 instance (s).

  Instance '+ ASM' READY State, has 1 operation for this service...

  Service 'ORCL12C' has 2 occurrences.

  Instance of 'ORCL12C', status UNKNOWN, has 1 operation for this service...

  'ORCL12C' instance, State LOAN, has 1 operation for this service...

  Service 'PDBORCL' has 1 instance (s).

  'ORCL12C' instance, State LOAN, has 1 operation for this service...

  The command completed successfully

  ..

  Concerning
