• ORA 12170: Connection timeout error: need help

  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 =
  (DESCRIPTION =
  (ADDRESS_LIST =
  (ADDRESS = (PROTOCOL = TCP) (HOST = 192.168.0.161)(PORT = 1521))
  )
  (CONNECT_DATA =
  (SERVICE_NAME = EGP)
  )
  )
  
  Please ask the community to help me overcome the error and making a link successfully. We have a system administrator, but not a database administrator. Oracle installation was made by me.
  
  Thank you

  Try adding a PGE in the SID_LIST_LISTENER of the listener.ora file and that you can do using the Net Manager and its operation is explained here

• 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

• ORA-12170: how to connect both ways 2 Oracle DB

  Hi all.

  I got the laptop Win7 64 bit and installed Oracle 11.2.0.1 32 bits. (sid = orcl, ip 192.168.1.101 =)

  Then I installed VM box and installed Windows XP as the guest operating system.

  Inside, I installed other Oracle 11.2.0.1 (sid = orclA, ip 192.168.1.102)

  I tried to connect the 2 database, but I had error ora-12170 round-trip

  I can ping both directions.

  Are there necessary permission grants on the side Win7 & WinXP so that my 2 databases can talk to each other?

  It seems to block the connection. I have already disabled the firewall.

  Please helppppp...

  Thank you very much

• ORA-12170 and TNS-12535

  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.

  2. place the database restricted and provided this user mode access restricted and tried the connection as long as that user, not luck.

  3A bounced the listener

  4A rebounded from the database

  5. some online forums suggest to increase the timeout setting in sqlnet.ora, in our environment, we use the OID and the sqlnet.ora is the central directory. If this cannot be the issue that everyone can connect.

• ORA-12170 of the client after installing 12102

  I installed 12102 on Linux.  In all my 11g install, our standard is to use dynamic record for each instance in the listener.  Then you remove the listener.ora file which allows dynamic registration in 11g.  We also use a listener shared by server... so I disabled the LOCAL_LISTENER parameter by alter system set local_listener = ";  I have found no record of this has changed in the 12 c install.  I found that a new process LREG registers the instance instead of PMON... but it's all working.  My cases are recorded in the listener... yet I can't connect from a client or another server using the standard tnsnames.ora.  What Miss me?  Nothing don't watch even in my journal of the listener that is trying to connect...

  ORA-12170 is one out of connection time.

  From there, we can draw some conclusions

  (1) your network service name WAS resolved to a connection string - left the tnsnames or a direct specifications.  We know because the request got fairly far from actually solved in a host address and an attempt was made to send the request to the specified host.

  (2) most likely, your application never made to the host.  He timed out waiting for a response from the host, he would have received if the request had never got there.  If the request had gotten to the listener, then failed for some reason, the error would be different.

  So, what does this leave us with?

  (1) the HOST = specification in your clien t tnsnames (or another method of specifying) is invalid, pointing to a non-existent host

  (2) there is a firewall blocking the transmission of your client to your HOST

• 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.

  I have also connected to these servers very well in the past with window 10 and Windows 7 so I think that the issue is a recent update of security Windows.
