After restarting the listener, we could connect using the connect identifier from the local server. However, when trying to connect from a remote client we received the error of "no listener". In the remote client the identifier is defined with host=ip_address. TNSping from the client to the host was successful.
When we changed listener.ora to host=up_address we could connect ONLY from the remote computer. Only after changing the host in tnsnames.ora file to the IP as well - we could connect from both the local server and the remote client.
I usually use host=localhost in the listener file (and the local tnsnames file) and never had this problem before.
I have a database up and running (including listener) on machine A. From that machine, everything seems fine. However, when I try to connect to it from another machine (say, machine B) on the network, the connection cannot be established (exact message: connection to database failed: The Network adapter cannot establish the connection).
I can successfully ping machine A from machine B. The machine A db is a default install (ORCL).
Is it possible the DB listener is not configured properly to connect to remote clients? On machine B, I have oracle tools such as SQLPLUS, Oracle Net Manager, and Net Configuration Assistant.
When i'm trying to connect my already-existing database, i get an error: "ORA-12505,TNS:listener does not currently know of SID given in connect descriptor.The Connection descriptor used by the client was: localhost:1521:xe".
i can't loose the builted tables and the information stored in them.My listener.ora file is :
I'm trying to connect a oracle client application on the client machine to a remote oracle server on the server machine but i get a connection fail.
On the server machine I configured oracle server in the following way:
Installed oracle server. Created a database "DB_Test" with the database configuration assistant Created a LISTNER with the Oracle NET Manager with the following parameter:
Protocol: TCP/IP HOST: server pc hostname (ENZOVAIO) or server machine address ip (192.168.0.71) in the network lan Port Number: 1521 Created "dbtest" service with the Oracle NET Manager with with the following parameter: Service Name: "dbtest" Protocol: TCP/IP HOST: server pc hostname (ENZOVAIO) or server machine address ip (192.168.0.71) in the network lan Port Number: 1521
All services on the server machine are running and I opened port number (1521) in the router. On the client machine I installed SQL PLUS and SQL Developer.
With SQL Plus as by the official documentation I have entered the following command:
CONNECT username/password@[//]host[:port][/service_name]. In my case is: CONNECT SYSTEM/oracledb@//ENZOVAIO:1521/testdb.
With SQL Developer I have entered the same parameter.
But with both SQLPlus and SQL Developer the connection fails.
there is a problem , related to toad. when i try to connect with my database through toad then it throws an error-"Can't initialize OCI. Error -1", how to sort out of this problem. and i am using toad 9.2.7.1 on widows server2008.
I am trying to read a message from Oracle queue using OCCI.I am getting this run time error:

*messageFromQueue = cons.receive(Message::RAW);
It seems like RECEIVE function is throwing this error: Here is my code:
it seems to me that the file tnsnames.ora is not read when i execute sqlplus.whit the command: sqlplus username / password @ servicename i receive the error ORA-12154, while if i pass the whole connection string i can connect without problems

When I try to remotely connect to an Oracle schema using SQLplus, I consistantly get this error:
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
Yet I can connect to the same machine, from my own machine just fine using SQLDeveloper.Here are the details I have collected so far
- I am using the instantclient for OS X - export DYLD_LIBRARY_PATH=/Users/jeff/instantclient - export ORACLE_HOME=/Users/jeff/instantclient - export TNS_ADMIN=/Users/jeff/instantclient/tns
The command line i ran : ./sqlplus seam_classoft/seam_classoft@//oracle11gtest.terida.net:1521/orcl
Its behind a VPN, so I'm not worried about posting my info.
My /Users/jeff/instantclient/tns/tnsnames.ora that I copied directly from the server looks like this:
I've tried changing SERVICE_NAME to SID = orcl, no change inbehavior. My original guess was that the database wasn't registered with the listener, but that would mean sqlDeveloper should fail as well, but it works.Here is out put of lsnctrl status:

I installed oracle 10g and developed simple software using forms 6i. Its working well as a stand alone system.
I want to share it in network. so I installed forms 6i as oracle client , copied the tnsnames.ora from the oracle installation path to forms installation path.(inside NET80/Admin folder)
When i try to connect with user name and password , it comes ORA-12203 Unable to connect to destination. I checked LSNRCTL in the database machine, it is listening.
I am using Report Builder 10.1.2.0.2. There is a table in a remote database with synonyms/links defined. I am getting error trying to access those tables. DBA says links/synonyms are correct and I am also able to access that table from SQLTool without error.
I can do a select statement on those tables from 'SQL Query statement' in data model.
Error is generated only if I try to use those tables in 'Formula' or in function/procedure.
I am trying to connect to a database located at my work from at home. I am running into the following issue (see command and error below):
ansichart@ansivm:~/src/perl$ sqlplus aspxdba/********@aspxp2 SQL*Plus: Release 11.2.0.3.0 Production on Thu Jul 18 21:15:09 2013 Copyright (c) 1982, 2011, Oracle.

I have verified that I can establish a TCP connection to this DB server on the port specified, using the same info from the TNSnames.ora file (see below):-

I have another terminal opened up to a server at work and I can connect to the DB with sqlplus just fine. I verified that the record for this database on the tnsnames.ora file is the same as it is at work. In conclusion, I can connect to the Database at work, but I cannot at home, even though I am using the same connection information and verified that port 1521 is accessible on this Database server from at home. So why can't I establish a DB connection?
I have a strange problem of connecting Oracle Forms6i from our Remote site.actually we change our IP address of lease line, we connect to it.but when we connect locally,forms are running without any problem,but when we connect globally or from other sites it can't able to connect,even sql prompt and toad also connect from remote site,but when we try to connect forms(forms runtime) it gives error message(ORA-12203: TNS:unable to connect to destination).when we connect this application from local application(Forms) it can connect well but from globally it can't able to connect.
I am able to connect to DATABASE from SQLAssistant only when I provide string like ABOVE........If I dont mention the SERVICE, m unable to connect to DB.Now the biggest issue is with SQL Developer.....m not at all able to connect to DB using SQL Developer.
I have created a function for knowing the status of link which connect me with remote database.function is as follows
--------------------------------------------------------------------------------------------- CREATE OR REPLACE FUNCTION get_status_db_link (p_db_link_in VARCHAR2) RETURN NUMBER AS rows NUMBER; v_code NUMBER; v_errm VARCHAR2(64); [code]....
Now functin should returns 1 when link is up and it should return 0 when link down but sometime when link is down it continues showing executing it hang my pc.
I've just instaledl APEX on Oracle 11g, with APEX listener 1.1, working fine at localhost. But I can't reach it from others computers on LAN. I searched several threads about this and thought I should run
EXEC DBMS_XDB.SETLISTENERLOCALACCESS(FALSE);
But when I execute that, I got the message 'ORA-30952: illegal configuration of HTTP/HTTPS in xdbconfig.xml'.
The problem is that this connection errors when I try to connect using my SQuirreL client. My developers want to connecting using the SID or the SERVICE_NAME and by using the "New Method" syntax, not the "Old Method" syntax. According to the documentation the "New Method" syntax works with the SERVICE_NAME or the SID. The "Old Method" only works with the SID.
# Host name is vmwwin7634.na.SAS.com # SID is sting2 # SERVICE_NAME is sting2.na.sas.com
PROBLEM using SID errors ==> jdbc:oracle:thin:@vmwwin7634.na.SAS.com:1521/sting2 THIS WORKS using SERVICE_NAME ==> jdbc:oracle:thin:@vmwwin7634.na.SAS.com:1521/sting2.na.sas.com
I am using SQuirreL Client version 3.4.0

I have new virtual UNIX machine and I installed oracle client on /usr/lib/oracle. Also I have a oracle database and I am able to connect to this database from my desktop sql developer.
So now I am trying to connect from new UNIX machine. Where I created tnsnames.ora file under /usr/lib/oracle/network/admin and before connecting did export the following
ORA-12545: Connect failed because target host or object does not exist. Not sure what I missed here. using same tns file I am able to connect from sql developer on windows.
I am new to oracle DBA. I have just installed the oracle on centos. when i create the oracle database for the first time then listener created and worked sucessfully. but when i stop the listener and start again. I get message "Listener does not currently know of services requested in connect descriptor.
