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 installed Oracle 10g XE and Toad 10.5 in my home system.I am able to connect to Oracle from Oracle XE homepage and XE SQL command line but when I try to connect to Oracle from toad 10.5 I am getting the error 'TNS: could not resolve the connect identifier specified (XE)'.From toad I tried direct and TNS options but it did not work. My tns ora file looks like below.
TNS_ADMIN variable has correct parameter and Toad is directing the correct TNS file. I tried changing hostname with my system's ip but still I am unable to connect to Oracle from Toad.
when i try to connect with sqlplus or toad then i get an error
Microsoft Windows [Version 6.1.7600] Copyright (c) 2009 Microsoft Corporation. All rights reserved. C:Users>sqlplus SP2-1503: Unable to initialize Oracle call interface SP2-0152: ORACLE may not be functioning properly C:Users>
and i want to tell what i do before it-my all files were be converted in .FLT then i shorted out this problem after that when i tried to connect with sqlplus or toad then i get above error.and i have restarted my system but throwing same error.

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
# Here is the tnsnames.ora entry on the server. STING2 = (DESCRIPTION =
[code]...
# In this documentation it says, "On new syntax SERVICE may be a oracle service name or a SID."You can find this on the orafax wiki under JDBC#Thin_driver.
# I was able to connect with the "old method" using the SID only, SERVICE_NAME errors jdbc:oracle:thin:@vmwwin7634.na.SAS.com:1521:sting2.na.sas.com (SQuirreL client error, "Unexpected Error occurred attempting to open an SQL connection.") jdbc:oracle:thin:@vmwwin7634.na.SAS.com:1521:sting2 (this works)

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.
Due to company restrictions, i unable to use oracle third party tools such as toad, pl / sql developer etc except oracle sql developers. I heard Oracle Developer Tools for Visual Studio is best option to work oracle pl/sql and sql.
I am using oracle 10 g on my pc .i have no issues while working on it but whenever i am not connected to the internet its says failed to connect.As most of the time i am not connected to the internet the isql plus browser would show the same error but the moment i connect to the inet,it works.
Is it that 10g isql plus wont work while not connected to internet ?
I was trying to connect to oracle 10g database from oracle 10g client. But unable to do so.
i am able to tnsping the db from client but unable to estatblish sqlplus connection. I get ORA-28547 error when i issue the command sqlplus hr/***@db1. ORA-1560 when the command sqlplus hr/*** is issued.
I have mentioned the listener and tnsnames.ora files
I have TOAD 8.6 installed and hoping to use with Oracle 10g databases. I have SQL Navigator also - it works fine. However TOAD does not. Open up TOAD and see the TNS dropdown, select a database and try to log in - click on Connect and the little SQL hour glass comes on, goes off - there is no error, no message and no connection. I have tried several databases and again, SQLPlus, SQL Navigator are both working fine.
Database is up and running and client machines able to do TNSPING; But when users try to connect the database thro SQL DEVELOPER, they are getting below information:
your database connection has been reset. Any pending transactions or session state has been lost.in the database server, SQLNET.ORA reads as below:
> more sqlnet.ora AUTOMATIC_IPC = ON names.directory_path = (TNSNAMES,EZCONNECT) names.default_domain = world name.default_zone = world sqlnet.expire_time = 15sqlnet expire time shows 15 min.
normally this error willbe suppressed if user tried after some time. But now we get this error for more than 2 hrs.
I installed Oracle 11g client and set the ORACLE_HOME and tns_admin env variables.I installed the pl/sql developer, but unfortunately after installing , i am unable to see any database details in the drop-down list of pl/sql developer.
I have installed and loaded a mssql express database on my pc for migration testing. When I test a connection from sql developer 3 receive "Failure -Test failed Cannot connect to Microsoft SQL Server on localhost. I am using windows authentication and SQL Server authentication and the default port 1433.
I'm not able to login to PL/SQL Developer 7.0.3.1123.I'm receiving "ORA-12154: TNS: could not resolve the connect identifier specified" error. Although it lists all TNS entries in Database drop down.It was working fine last week but now I'm not able to login.
i am using client-server environment without using a domain.On One computer i have installed Oracle 8.0.5 and developer 2000. and on client side i have installed form 6i. i have made a service (star) in Tnsnames.ora in client side.
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 :
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.
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 have registered an APEX (Oracle) online database and I can connect to database online.But my problem is how to define a connection string that can connect from the program written in C# to connect to APEX account(apex.oracle.com).I even don't know how to use the tool Oracle SQL Developer to connect to APEX account.
