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:
LSNRCTL> status Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521))) STATUS of the LISTENER ------------------------ Alias LISTENER Version TNSLSNR for Linux: Version 11.2.0.1.0 - Production Start Date 07-JUN-2010 09:16:40 Uptime 42 days 0 hr. 58 min. 59 sec Trace Level off [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 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.
Acer laptop, Intel Processor w/ Windows 7 Professional (64-bit) Delphi 2010 Professional Oracle XE (+ the Oracle XE client that comes with it)
I cannot can't to the Oracle database from Delphi. The error I keep getting is:
Alias is not currently opened. [Oracle][ODBC][Ora]ORA-12154:TNS: could not resolve the connet identifier specified.
Here's what I've done:
1. Create an ODBC connection to my Oracle database
- run C:WindowsSysWOW64odbcad32.exe to open the ODBC administrator. - Data source name: bt_user - TNS Server Name: localhost/xe - user bt_user - Clicked "test connection" -- Success.
2. Open Delphi and drop a TDatabase component on my main form.
- Set the Alias Name property to "bt_user" (the alias I set up in ODBC) - Set database name to "bt_user". - Checked "connected".
Alternatively, I tried using the Delphi ADO components (the dbGo components).
- Drop TADOConnection component on my form. - Select "connection string" and open the dialog. - Click "build string". - Select "Microsoft OLE DB Provider for ODBC Drivers" from the selection. - In "use data source", select "bt_user" from the drop-down list (my ODBC connection from #1) - Click "test connection".
Again the same error.
My questions are:
1. Can Delphi work with Oracle XE (Express Edition)?
2. If so, then do I need to install the "Instant Client"?
3. Will the instant client for Oracle 10g work with Oracle 10g XE?
4. Do I need to install any additional ODBC driver(s)?
5. Why was I successful in creating the ODBC connection in Windows, but it failed in Delphi?
6. Will Visual Studio.NET (C#) work with Oracle XE, and what are the steps for setting that up?
after connecting to database using username and password , i get below error message connection is established and able to work asusal,

I need to login remote DB writing a shell script where our DB is on a separate node, i have to test the script only with
SCHEMA USERNAME PASSWORD HOSTNAME PORT NO SID/SERVICE NAME
these details. May be am wrong to ask this question but i need to login and check the requirement. Is there any other anyway to login without sqlplus utility?
For example, I have 3 database, database 1 and database 2 connect together by database link db_link1, database 2 and database 3 connect together by database link db_link2.
I want to ask: Can I connect from database 1 to database 3 ? ( Of course don't use database link between database 1 and 3, just use database db_link1 and db_link2 )
Both db_link1 and db_link2 are public database link.
Can I restrict user access by 2 these public database link ?
I am not able to connect to database due to ORA-257. So manually i deleted the archivelog files in diskgroup. however it is showing 13gb free space after deletiion. Archive log files generated due to Import job is running.

I do not know how to create a connection between oracle to SQL server using topology manager on my application. I understand that I must create a logical and physical architecture to create the connection and the logical and physical architecture is running under topology manager.
I extracted the script of creating user in my database in SQL navigator and Toad tools but it is displaying encrypted password. But I am unable to connect with that password.
To get the original password then I will be able to connect my database.
I'm writing PRO C program with oracle 8i. My process first connect to the database with using ora_connect(), proceed the task then diconnect with using ora_disconnect().

I am trying to develop a web application with C # VS.net, my application is to connect to an Oracle database on a server (LAN), the problem I want to connect to the database without install oracle or ODP on my client machine.
I recently installed Oracle database 11g XE onto my home computer running Windows 32 bit, but I can't connect to the database. I also have Oracle 10g R2 installed on my computer, and I can still connect to it finely. When trying to make a connection in SQL DEVELOPER, I get this error
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
I tried to tnsping the XE database and it returns successfully.

When I created the database the connection I used was s7s but whether or not I include that name or just use the ID/password that script will not connect.
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 installed Oracle Express on my Windows 2003 Enterprise server. And right off the bat I cannot connect to it via command line. I have googled and read many sites, but am still getting the same error, no matter what I do. I am newbie again (was a DBA in 1990...when I used to have the same error and fix it in seconds...not sure why this problem still lingers in Oracle) so most likely I am overlooking something. Below are my tnsnames.ora and liserner.ora files
# This file is actually generated by netca. But if customers choose to # install "Software Only", this file wont exist and without the native # authentication, they will not be able to connect to the database on NT.

I have intsalled oracle client 9i.I add my services into tnsnames.ora .I could connect in sqlplus but in Enterprise manager i receive error ora12154 tns could not resolve service name!
I cant able to connect to my local DB instance. Oracle service for DB instance will be started running when the system boots automatically.I faced this problem before, I was instructed to boot my system without network connection. It worked for few days. Suddenly I cant able to connect to my local DB instance again, even though I am booting my system without network connection.
This is the configuration I have in tnsnames.ora in my local machine.I have the host as localhost, because local machine is laptop and IP will change periodically.
how to connect to sql server databases via toad. I have used toad to connect to oracle databases, but never to a sql server database. To connect to an oracle database, we first install the client and then add the tnsentry of the database to the tnsnames.ora file and then we can directly connect to the oracle database right?So I was wondering if there are any steps like that to be followed to connect to the sql server databases.
Am getting the following error while connecting db from sql dev "network adapter could not establish connection vendor code 20"
