ORA-12170:TNS:Connect timeout occurred

Hi, I am no longer able to log into SQL Plus. I get the error message above. I think the problem comes from my comtputer being renamed. Can someone help me?
Thanks.

ORA-12170:TNS:Connect timeout occurred
Cause: The server shut down because connection establishment or communication with a client failed to complete within the allotted time interval. This may be a result of network or system delays; or this may indicate that a malicious client is trying to cause a Denial of Service attack on the server.
Action: If the error occurred because of a slow network or system, reconfigure one or all of the parameters SQLNET.INBOUND_CONNECT_TIMEOUT, SQLNET.SEND_TIMEOUT, SQLNET.RECV_TIMEOUT in sqlnet.ora to larger values. If a malicious client is suspected, use the address in sqlnet.log to identify the source and restrict access. Note that logged addresses may not be reliable as they can be forged (e.g. in TCP/IP).
1. Check whether database is up and running.
2. tnsping <databasename> and see whether you are able to ping the database in command prompt.
3. Check tnsnames are configured properly.
4. check DNS entry in your host file.

Logging in Oeacle SQL*Plus (ORA-12170: TNS: Connect timeout occured) ...

I installed recently Oracle 10g. When I try to log in, with the account and password setup[ earlier, I get the message "ORA-12170: TNS: Connect timeout occured". Do I need to specify a Host String" at Log On? Should I un-install and re-install the software again? Thank you.

ORA-12170:TNS connect timeout occured.

HI, i am getting this error when trying to connect, sqlplus, form builder in devsuite.10.1.0
can anyone help, plz........................
ORA-12170:TNS connect timeout occured.
with regards,
AJAZ.

In $ORAHOME/network/admin on the machine where you have Forms Builder installed, there is a file called tnsnames.ora
This file maps the 'tns name' which you are probably using in your connect string, to a specific TCP/IP port (and 'service identifier') on the database host.
A TNS connect timeout could occur because:
a) a firewall is preventing communcation between your machine and the database host/port in your tns definition
b) the TNS 'listener' on the database host at that port is hung
For my money, I'd be investigating (a) first.
It's worth investing time in learning about TNS. It will save you a lot of hassle.
regards,
David.

OO4O - Unable to make connection, ORA - 12170: TNS: Connect timeout occured

Hi,
I am trying to connect to the Database server from Vista client using code written in VB 6.0, The oracle client installed in Vista is 10.2g
I am using the below code to connect to the oracle database. I tried increasing the INBOUND_CONNECT_TIMEOUT parameter in the SQLNet.ora file, but didn't work.
Set gvobjOraSession = CreateObject(gvOraSession)
Set gvobjOraDatabase = gvobjOraSession.OpenDatabase(gvOraDBName, gvOraDefaultUser & "/" & gvOraDefaultPassword, vOraMode)
Thanks for the help in advance
Anand

Are you able to connect using the same information with sqlplus from the same client machine? 12170 is usually a basic client config issue rather than something specific to OO4O.

ORA-12537 TNS Connection closed after OAS 4.0.8.1 Installation

finally I was able to install and start OAS
on RH 6.1, but now I can not start Ora8i (with all patches) on my system. When I start svrmgrl, will get ora-12537 TNS Connection lost error.
Can someone please help!
Thanks

They said in the install doc that you can't use the same ORACLE_HOME for 8i and OAS 4.0.8...

C# code:

objConn.Open(); always ends with "ORA-12564: TNS:connection refused"
I've even tried to let the connection build by ODT connection wizzard ('Test connection' button displays 'Connection was successfull', but when the code is run the result is unfortunately the same :(
Anybody knows where the problem should be?

This is often a malformed tnsnames.ora. Is what you posted a snippet, because it looks to me that you a closing ) too many. You can turn on tracing which should help you find the problem. It's odd that odt says the connection works, though.

I'm trying to connect to my home wifi with my imac gh5. After I enter the password it says connection timeout or password incorrect. I know there's no issue with the connection but I don't know what else to do. Does anyone know how to fix this problem?

What is the make & model of your home Wi-Fi router that you are attempting to connect your G5 iMac to? Which exact model of iMac do you have?
What wireless security type is your router using: WEP, WPA, or WPA2? If you temporarily disable wireless security, can the iMac connect to it now?

Ora 12170 tns delai

dear all ,
I have a problem connecting my client to a the ORCL database on a small lan in my lab, first i get a timeout ORA-12170, after that i figured out that i am using a firewall , so i deactivated it , so it works fine.
my question is how could i keep my firewall on and achieve the connection, since i am working in a TCP/IP environment using windows OS:
-which port do i have to open?
-if the port changes dynamically how could i deal with that ?
thanks in advance.

for 1st point
- Open "Net Manager" --> Local --> Listener --> Select the listener_name
then "Add Address" with different ports.
after adding address your listener.ora will start showing like that
LISTENER =
(DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = host_IP)(PORT = 1521))
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = host_IP)(PORT = 1522))
)- Then Stop & Stop the listener using lsnrctl.
for 3rd point
you have to define new variable USE_SHARED_SOCKET = True in
My computer property --> Advance --> Environment Variables --> system variables

ERROR:
ORA-12560: TNS:protocol adapter error
This is a local connection (called an internal connect in the old days). The connection does not go via the Listener. It is a local IPC connection. And as you can see, you do not supply a database schema and password as credentials - the o/s user and environment need to provide the credentials.
So I would not expect a TNS protocol adapter error, as this usually indicates a network driver related problem.
For a local IPC connection to work, TWO_TASK must not be set, and ORACLE_SID and ORACLE_HOME must be set (and valid). The local client driver needs to launch an Oracle server process (dedicated server process to service the client driver). It finds that executable in ORACLE_HOME/bin. Next it needs that server process to "attach" itself to the database's brains (the SGA). This shared memory area is identified via the ORACLE_HOME and ORACLE_SID variables.
There also is a requirement that the dedicated server process created, has the o/s permissions to attach to the SGA - which means it needs to be run as the same o/s user as the owner of the shared memory (in other words, the client should be running in the same o/s user as the database processes).
Thus the need to have these variables set. And no need for using a Listener - it is not a factor.

The problem comes into play when you try to select the actual LOB locator remotely, however straight INSERTs aren't a problem.

How to handle the error when using Connection.setAutoCommit()

I think it is because there is something wrong with the
