Tnsnames.ora in SQL Developer 3.0.04

Hi!
I've previously used both Toad and SQL Navigator on this computer, and they were both able to connect to all the connection strings in tnsnames.
I've manually tried adding environment variables, and setting the directory under Tools --> Preference --> Database --> Advanced.
The path is C:\Program Files\Oracle\ora92\network\ADMIN\tnsnames.ora.
When I try to create new connections, and chooses tnsnames, the drop down menu is empty.
Could you please help me?
Thanks and regards

SQL Developer is very sensitive to syntax errors in tnsnames files which are ignored by other tools including sqlplus.
Check the file very carefully for errors. Try reducing it to a single definition and adding definitions back in gradually.

Import tnsnams.ora in SQL developer on Mac OS

Hi, I am moving from PC to Mac and am installing SQL developer on Mac OS. I want to import tnsnames.ora ( that I used in toad ) to SQL developer. I looked it up and everyone seems to say drop tnsnames.ora to /etc, sql developer will pick it up. However I don't have root access to /etc directory.
What can I do to import tnsnames.ora
Thanks!

You can put tnsnames anywhere you like and specify it via the TNS_ADMIN environment variable (though the next problem you will have is ensuring that the SQL Developer process can see that variable). The standard location is in network/admin under your Oracle Client installation. The reference to '/etc' is to do with database servers. You can put your own files in /etc if you want using sudo (it's your Mac), but I'm pretty sure that would not help here.
However it's news to me that SQL Developer can even use TNS name resolution. I thought it was all JDBC. Are you sure?

Oracle 10g I don't have the files listener.ora, tnsnames.ora and sql.ora

Hi folks,
I uninstalled my Oracle 10g and when I re installed I got success, but when I went to the folder \network\admin didn't have the files listener.ora, tnsnames.ora and sql.ora. I have been trying during more than one month start my listener only because I need access the Oracle database from my Java application and I got the message:
java.sql.SQLException: Io exception: The Network Adapter could not establish the connection
As additional information, I got no problem to access the SQL*Plus.

Thanks ALL, I GOT IT, but I used other solution.
Since I installed and uninstalled the Oracle several times, it keeps also many different Services for the listener. I don't know why, it didn't create a Service for my actual instalation with its path. In other words, all the services remained in the services.msc panel, had the path that was already removed from the Windows folder.
Then what I did, was that I picked one service, took its name (OracleOraDb10g_home1TNSListener), went to regedit to [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\OracleOraDb10g_home1TNSListener] and simply changed the image path that was setted for the one that was removed (C:\oracle\product\10.1.0\Db_2\BIN\TNSLSNR ) for mine that is installed right now
(C:\oracle\product\10.1.0\Db_1\BIN\TNSLSNR). Nothing more and finally works.
I have tried something in the services.msc panel before, as you can see in this forum at the thread "I can't start listener in the Control Painel/Admin Tools/ Services", but I never got
success.
Appreciate your time!!

TNS_ADMIN not respected, or how do I get sql developer to see my tnsnames

When I installed sql developer at home with a 'static' tnsnames.ora file, sql-developer picked it up right away, and I was able to use the 'connect identifier' pull down menu.
However, at work, all of developer's computers have a TNS_ADMIN registry set pointing to a network share. Sql developer fails to recognize that. The purpose of this is central administration of the file (changes happen at least once a month)
Is there are a way to make it see our tnsnames.ora file? Is there are some kind of workaround (besides copying the file locally)
Thanks.

Unfortunately, because SQL Developer is set up to allow an install without any local Oracle client, it is not wonderful at picking up some things from the local Oracle client when it is there - such as the TNS_ADMIN setting.
Assuming you are on an Windows box, rather than having your TNS_ADMIN set in the HKEY_LOCAL_MACHINE\SOFTWARE\Oracle registry 'directory', you need to have a Windows environment variable set for TNS_ADMIN (it doesn't matter if this is a User environment variable or a System environment variable). I assume (but don't know) that on a Linux based version you need a Unix environment variable set.
For example on Windows XP, right click on My Computer and select the Properties menu option. On that page, select the Advanced tab and then the Environment Variables button. Then click on the New button (in either the System or User section) and enter the variable name TNS_ADMIN and the variable value that you are using in the registry (ie z:\orant\network\admin).

Which oracle_home SQL Developer 3 uses

Hi, all,
I have multiple oracle homes in my desktop.
How do you know which oracle SQL Developer uses? I'm trying to figure out which tnsname.ora file SQL Developer refers to.
SQL Developer version: 3.0.04
Thanks!
alex

You can find/change the path in Preferences - Database - Advanced - Tnsnames Directory.
Have fun,

Proble to connect oracle DB from Sql Developer

1st I installed fedora 13 on VirtualBox 4.1 machine and then i installed a oracle 10g(the db run correctly and listener too).
the listener paramater:
LISTENER =(ADDRESS_LIST=(ADDRESS=(PROTOCOL=tcp)(HOST=10.0.0.8)(PORT=1521))
2nd in my local machine (Fedora 13 too) i installed a sql developer and when i trying connect to oracle on virutal machine i recived a next error
using connection Basic:Status: Failure -Test failed: IO Error: The Network Adapter could not establish the connection.
the parameter i settings are:
connection name:XXXX
username name:user_created
password:XXXX
Hostname = 10.0.0.8
port = 1521
SID = the_same_of_database
i can make ping well to the virtual machine.
using connection TNS: Status: Failure -Test failed. Required property 'hostname' is not set on the DatabaseProvider.
But i don't know where is the tnsnames file for sql developer.
i don't know if i have to install any JDBC for sqldeveloper.
i can't make tnsping because on my local machine i don't have installed.

Use of tnsnames.ora

Hi,
Pls help me..
i want to know the use of **tnsnames.ora for oracle developer and also about listener.ora**
pls let me known clearly..
advance thanks....

Welcome to the forums.
This is not a SQL or PL/SQL topic, is it? Please choose forum for your product/topic wisely.
What you ask about is very well documented in the Net Services Reference for your version (of Database).
http://www.oracle.com/pls/db112/portal.portal_db?selected=4&frame=#network_management
Note that reading the documentation - after learning how to find and navigate it - is best not avoided and highly recommended (to say the least), when working with Oracle products.

Cannot find tnsnames.ora error message

We are using oracle 10.2.0.1 via Toad. I get a cannot find tnsnames.ora file error message and see only a tnsnames.ora file in the sample file under the c:\ORACLE\product\10.2.0.1\NETWORK\ADMIN\ directory.
Do I need to create this file, and if so how do I do this?
Thanks in advance for your help

user12943453

Do I need to use the TNSNames Editor? No need for tnsnames.ora or SQL*net to access local DB
Can I just use direct connect and the sqlnet editor?YES!

SQL Developer 2.1.0.63 duplicate TNS names displayed in the Connection Type

I'm running SQL Developer 2.1.0.63. The New Connection window displays duplicate Alias names when you select the Connection Type of TNS. I've made sure that the TNS_ADMIN variable name is all in upper case in the Environment Settings but I haven't had any luck eliminating the duplicates. I've tried filling in the TNSNames directory on the preferences setting but this didn't help either. I've also checked my system and I don't have multiple version of TNSNAMES (we keep a public copy on a network share). Does anybody have any suggestions?
We also have SQL Developer 1.5.5 and we don't have this duplicate problem in that version.

I found the problem, it was in the TNSNames file. SQL Developer 2.1 is more sensitive to a messy TNSNames file. This past fall we reworked our environment with new hardware and OS software, during the multiple rounds of testing we created various temporary test databases. The entries that were added to the TNSNames file never got cleaned up and in some cases were added in a random fashion. After I went in and cleaned up some of the old, dead entries I noticed that there were duplicate entries for one of our Development databases. After I removed the duplicate entry in the TNSNAMES file all of the duplicates displayed on the Connection Type screen disappeared. Problem solved.

DBA studio: Error add/connect database "Failed to parse tnsnames.ora file"

I have Oracle (version 8.1.7) installed in my XP machine and when I try to (having chosen "Launch DBA Studio standalone") to open a connection I get:
"Failed to parse tnsnames.ora file
ERROR: 100 -- NLNV-NLNV String Format Error".
Also got this when I tried to manually add a database to a tree.
I can access the databases listed in my tnsnames.ora using SQL Plus with no error.
This is my tnsnames.ora.

Does anybody have any idea what is wrong? Thanks a lot. Changsong

Just found out this IS a string error in my Tnsname.ora. What i did is deleting all the entries in my tnsname.ora, and start adding each one back. I found one particular entry is responsible for the error. This is the old text
serv32.xxx.ge.com =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (COMMUNITY = TCP)(PROTOCOL = TCP)(HOST = sevr32.xxy.ge.com)(PORT = 1521))
(CONNECT_DATA = (SID = atmo32))
just looking by itself I can't see anything wrong. I just formatted it a little, making it looked like the other one that is working
serv32.xxx.ge.com =(DESCRIPTION =
     (ADDRESS_LIST =
     (ADDRESS =
     (COMMUNITY = TCP)
     (PROTOCOL = TCP)
     (HOST = sevr32.xxy.ge.com)
     (PORT = 1521)))
     (CONNECT_DATA=
     (SID = atmo32)))
and now it works fine. I Really can't tell the difference, except that some words were moved to the other line. What puzzled me is that the same old tnsname.ora worked in almost all the other circumstances, like sql plus, and other database enginee. But it is just not good enough for dba studio?
I admit I probably should have used the network utility to add a connection to avoid this type of format error.
Anyhow, I'm glad it is solved. by the way, the symjct.dll mentioned in the previous post should be symcjit.dll. I guess he mispelled the name. I renamed it to symcjit_old.dll and now the java error was gone. So that is another gain from this post. Thanks Joel for all the information.

Tnsnames.ora file does not seem to load in SQL Developer

I've really tried my best to figure this out on my own ... through the Help, this forum, and Internet in general. I apoligize in advance for having to ask this, since I'm sure this is a common issue. This particular form entry was really close:
Database Connections will not load tnsnames.ora
But, I just can seem to figure out why, or where entries from my tnsnames.ora file are loading into SQL Developer.
- I have the TNS_ADMIN system environment variable defined to the directory where tnsnames.ora is stored - C:\oracle\product\10.2.0\client_1\NETWORK\ADMIN.
- I do not see a TNS tab as the forum entry above indicates anywhere in SQL Developer - This may be my problem.
It seems that this issue could be cleared up with better directions on how to import tnsnames.ora entries into SQL Developer. Is there any specific direction on how to get your tnsnames.ora file setup correctly with SQL Developer running on Windows XP - Besides the Help which mentions the setup of TNS_ADMIN, but doesn't really tell you what the expected result is, or where the entries will be, or how to verify this is working?
Any help would be most appreciated.
Thanks,
Dave

Using Windows XP/Vista...
After testing in our environment, it appears that SQL Developer 1.5.1 (5440) does in fact ignore the TNS_ADMIN environment variable and ONLY looks in the Oracle Home directory (network/admin). We define a central network location for our tnsnames file and have the tns_admin setup to point there instead of locally for our users.
When selecting to add a new connection (in 1.5.1, it works in previously releases... meaning 1.2.something) and selecting TNS, the drop-down remains empty. However, if I exit SQL Developer and then copy the tnsnames file to the local network/admin directory I can then re-launch SQL Developer and the drop-down is populated. Exiting SQL Developer again, deleting the local copy of tnsnames, and then launching SQL Developer yet again results in the drop-down being empty.
All other Oracle-related applications function as expected (as they have for years) using the TNS_ADMIN environment variable.
Any suggestions/ideas?

SQL Developer not only reading tnsnames.ora

Hello,
I have found a very odd behaviour in SQL Developer 1.2 (running on Windows 2000):
I have set TNS_ADMIN to point to a directory on a network drive residing on a Linux host. In this directory there were many backup files of tnsnames.ora created over time whose names followed the pattern tnsnames.ora.<timestamp> or tnsnames.bak or something similar. In SQL Developer in the "New database connection" dialog many TNS-entries showed up multiple times in the "Network alias" listbox. Only after removing all those backup files from the directory the behaviour of SQL Developer was correct and every entry only showed up once. I also found out that even when I moved the backup files to a new directory "tnsnames.bak" under the directory which TNS_ADMIN points to the entries showed up multiple times. After I renamed this directory to bak.tnsnames the behaviour was again correct. In my opinion SQL Developer should only read the file called tnsnames.ora and ignore all other files or directories with similar names.
Kind regards,
Christof Breker

Various users reported this before.
Maybe others use multiple files, but at least there should be the option to read just this one.

Kristof

SQL Developer can't see tnsnames.ora

Hiya. I hope someone can help with this. I installed Oracle instant client (basic lite) on my new Windows 7 machine (32 bit) - yeah, I know Windows 7 is not supported, but my gut feeling is that this isn't the issue I'm having.
I've put my tnsnames.ora file in the same folder as instant client (C:\program files\oracle\instantclient), have created a system environment variable TNS_ADMIN which points to that folder, and have added that folder to the system "path" environment variable. That should do it, right?
When I try to create a new connection in SQL Developer 2.1.0.63, and change my connection type to "tns", I don't see any database connections.
Troubleshooting ideas? Other ways to test that the needed Oracle files are installed properly?
Thanks!

Here's how to debug where it's looking:

SQL developer cannot see connection info from tnsnames.ora file

Greetings All,
I have been using sql developer for a while. Currently on 3.0.04.34.
I have 16 database connections.
Everything was working fine until yesterday.
Today when I tried to connect to a database from the list of connections I am getting following error:
Invalid connection information specified. Verify url format for specified driver.
When I pull up the property for this connection -connection type is still TNS, Netwrok Alias is now greyed out and what was in Netwrok Alias has shifted to Connect Identifier.
When I try to create a new connection I do not see entry from tnsnames.ora file for the databse I am trying to connect to in the Network Alias drop down list.
I can connect to this database from sqlplus.
Has anyone seen this behavior? Does any one know the fix for this?
Thanks.

Hi,
Maybe your preference settings got corrupted, or the Tnsnames.ora file got moved to somewhere SQL Developer can't find it.
Are you using either:
1. Tools|Preferences|Database|Advanced|Tnsnames Directory, or a
2. TNS_ADMIN environment variable
to point to your Tnsnames? Having one of those should enable the Network Alias drop-down list to get populated. Otherwise, if the values moved to Connection Identifier are correct, then you won't be to connect in that mode without also having an Oracle client installed with an 11.1 JDBC thick driver (ocijdbc11.dll).
If there is no issue with the Tnsnames. ora location, it might be a good idea to use Export Connections to make a backup of your connections. Then you can try deleting the connections from SQL Developer and re-importing them. Even if that doesn't fix the problem, you should be no worse off.

SQL Developer is not able to identify the Tnsnames.ora file

Hi,
I have installed the following in the laptop having Win XP:
1) Oracle 10gR2 Client software in the D: drive of laptop. Tnsnames.ora is located in this clients Network\Admin path. This client is used to access the databases on the other servers.
2) Oracle 10gR2 Database software in the E: drive of laptop. Right now there is not Tnsnames.ora file in this softwares Network\Admin path. This db software has been installed to create local databases in the laptop.
3) Oracle SQL Developer Version 2.1.1.64 is also installed in C: drive of laptop.
The problem which now I'm facing is that the SQL Developer is not able to identify the Tnsnames.ora file mentioned in the above point-1 which contains entries of databases on the different servers. Could you please help me out in solving this problem?
Thanks in advance.
MAK

I forget what version I was using at the time, but when I had an ORACLE_HOME defined for the environment and TNSNAMES file defined in SQL Developer (different one than was in ORACLE_HOME), that I would see results from both tns files. I don't know if that is still the case. I have since dropped my ORACLE_HOME environmental variable.
