How to solve Oracle SQL Developer connection problem ?

Folks,
Hello. I am using Oracle Database 11gR1. The Database Control Console https://localhost.localdomain:1158/em works correctly. I can create a Database and a table successfully.
My OS is Linux and connects to internet successfully.
In order to run SQL statements. we need to use Oracle SQL Developer. I connect Oracle SQL Developer in the following way:
Connection Name: DB1 (this is my database name as well)
Username: SYS (this is the user name I used to login to the Console)
Password: SYS (this the password used to login to the Console)
Connection Type: Basic
Host Name: localhost
Port: 1158
SID: DB1 (this is created during installing the Database)
But the error message comes up: "Status: Failure - IO exception Connection Reset."
Can any folk tell me how to solve Oracle SQL Developer connection problem ?

Can any folk tell me how to solve Oracle SQL Developer connection problem ?username: sys
password: enter_your_correct_password given at the time of oracle installation
role: select sysdba if you would connect as sysdba else select normal for users other than sys
hostname: enter your oracle server hostname or ip address eg:- 192.168.11.12
to find the hostname open terminal/command prompt in oracle installed machine
type ---> hostname
type ---->ping hostname
you can find the ipaddress of the server
port number: 1521 (default) ----> i guess , else check the port number in the tnsnames.ora file under your ORACLE_HOME/network/admin folder
SID: DB1
try it
Good Luck

Oracle/ SQL Developer connection problem.

I have installed Oracle 11 g and SQL Developer, When I open SQL Developer and try to make a new connection ( I name the connection, put a user name in, put my password in), I click on "Test" and I get this error:
Status: Failure - Test failed: Listener refused the connection with the followong error:ORA-12505, TNS: listener does not currently know of SID given in connect descriptor The connection descroptor used by the client was:localhost:1521:ex
Can anyone explain this to me and help me resolve this issue I am having?
Thank you in advance for your help
-steve
p.s. I have also tried the user name: Scott and Password: Tiger

Windows 7 Home ... will have challenges at some point, as Oracle may not be completely compatible with Windows 7.
Aside from that, you may find firewall issues even if you are on the same machine, since the default connection from SQLDeveloper is to use the network (even loopback).
First step is to verify that the database and listener are running and that the database is registered to the listener. TO do that, drop into command line and issue:
1) Listener
lsnrctl statuswhich will give one of two results, if properly installed. First - listener is down

The command completed successfullyIn the above, remember the "xe" from 'Service "xe" has 1 instance(s).'. I expect to see something about that in the TNSNAMES.ORA file in your ORACLE_HOME\network\admin directory. That file should have an entry like
XE =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = FCC003L)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
)and you will note the XE on the left side of the equal sign (which is a network alias), and one XE in the (SERVICE_NAME = XE) line. On YOUR system, the XE should be replaced by whatever you called your database (often 'orcl'). REMEMBER THIS ALIAS;-) and also make note of the host that your entry uses. If your host name changes because of DHCP, you're hooped (for a while).
If the database is registered (shows up in the list), the next step is to make sure a userid is available. You could use 'system' (try to avoid using SYS since it is the master userid and if you mess that up, you mess up all your homework. In a production encvironment, every access to SYS will be audited.
So, let's create a userid called me with (in 11g case sensitive) password 'myself'. Make sure that user is allow to log in (create session) and create a table.

Do you remember the XE discussion above? Replace XE with the one on the left of the equal sign - the system looks that up to find which service it wants to access.

If it did not work, try dropping the "@XE" to see whether you can get in (using the bequeath connection) which is useful for troubleshooting but will not help with the traditional SQLDeveloper connection. If you get in without the @XE (or whatever your alias is) but not with it, most likely either your listener is not up or your firewall is blocking the access to the listener.

How to use Oracle SQL Developer 4.0 to connect to Ms Access file with .accdb extension

Hi all,
I am using Oracle SQL Developer 4.0 and Ms Access 2013 under Windows 7 (64 bits)
After browsing and selecting MS Access file with accdb extention, I got an error message :[Microsoft] " Data source name not found and no default driver specified".

Would you please advise?
Thank you very much in advance

That MS Access driver is 64-bit, I think. If SQL Developer, or JDK is 32-bit you need to use the 32-bit driver.   You can see if you have a 32-bit driver installed using c:\windows\system32\odbcadm32.exe

How to lock Oracle SQL developer 1.5.1

Hi,
If you run a PL/SQL block on a page that takes some time and while still processing you try to see a table it locks.
Running: Windows XP, Oracle SQL Developer 1.5.1, jdk 1.6.07, Orcacle 10g.
Greetings,

This is well known. Everything uses the same connection so while the query is busy, you can't do anything else.
The workaround is to use the Unshared Worksheet feature. Typing ctrl-shift-N in a worksheet will create new worksheet using a copy of the current connection.
Unfortunately, unless you remember to do this first, the object browser is still unusable because it is using the same connection as the original worksheet.

Oracle SQL Developer Connection Help

Hi,
I'm a complete Oracle newbie, so please bear with me. I've been doing research on protein clustering and at my lab the SQL developer has been running queries that I can then do statistics on. I have the query that I need to run, and was told to download Oracle SQL Developer and Oracle Client.
I was also given a username and password, a hostname, a port and a SID. I'm a bit confused, do I still need to install Oracle Client? And if so, I can't quite find what it is on the website? I have SQL Developer installed but when I click connect I get:
"Status : Failure -Test failed: IO Error: The Network Adapter could not establish the connection"
I'm pretty computer literate outside the world of databases so if someone can offer some explanations and guidance, it would be appreciated!
Thanks!

Thanks!If you have SQL Developer installed & need to connect to some Oracle DB,
then you do NOT need Oracle client.
FWIW - SQL Developer is written in Java & uses JDBC (thin) to connect to the DB
Is the DB Server on a subnet local to your system?

Oracle sql developer connection error

Hello everyone;
i have recently installed oracle sql developer on linux, i have been using oracle sql plus tool to access oracle; but when i am tryin to connect to oracle with sql developer its giving errors,
Error says:
an error was encountered performing the requested operation;
io exceprion: The network Adapter could not establish the connection
vendor code 17002
now i dont know what to do? Is there who can help me pls, i think i am close: is there any .xml file anywher in my database which i have to get connection details from? If yes pls lemme know. Thanks.

This typically indicates that the connection to the database was unsuccessful (incorrect values in client tnsnames.ora). Are you able to tnsping the database successfully from the client ?

Oracle sql developer downlaod problem

hi
i put my oracle sql in C drive,but when i open it ,it gives me error like :"unable to find main class.Class specified is :oracle/ide/boot/Launcher
can anybody has solution
thanks a lot in advance

I have the same issue...
I've just downloaded
Oracle SQL Developer 2.1 Patch 1 (2.1.1.64.45) Oracle SQL Developer for 32-bit Windows (This zip file includes the JDK1.6._11)
I extract it straight to the c:\ drive making sure I select "Keep folder structure", double click the sqldeveloper.exe executable and I get
"unable to find main class.Class specified is :oracle/ide/boot/Launcher"
I noticed I have a directory and an entry in my environment path of :-
C:\jdk\bin
which holds a JDK v5.0 in it (don't know why it's there, I didn't build the machine).
Could this be a reason for my issues?

Thank you for your understanding!welcome to the forum,
what is your operating system name and version?
check
$lsnrctl status
if the listener is down
start the listener
$lsnrctl start
also check the database is up and running.
and try to connect with correct username,password,role (normal or sysdba) hostname or IP, port number, SID or service name.
Good Luck.

SQL developer connecting problem

Hi,
our remote server has oracle 8 and Oracle 10G. Oracle 8 installs very long before and oracle 10G installs today.
As sql developer cannot support to 8i; when i try to connect to oracle 10G i get the following error. ORA-12505
I have oracle in my laptop and can connect via sqlplus but cannot connect with sql developer.
C:\>sqlplus sys as [email protected]:1521/xxxx
password:
SQL>
Thanks.

Hi,
Not sure if you are running two listeners (one for 8i, one for 10g) on that server. When I had problems connecting to 10g XE and 11g running on the same server, each with its own listener, I read that disabling the 10g listener and updating the 11g listener.ora and tnsnames.ora with entries for 10g solved everything. Always use the listener for the newer Oracle release. Possibly you do not have control over the listener configurations on the server, but this is something to consider.
And here is a thread from a different forum with opinions on when single or multiple listener configurations might be preferred (and some info on how to do it):

I'm finding it difficult to connect my downloaded sql devloper to the oracle. I am doubting if my login details were correct, or there re some other configurations that needs to be done. Please can you tell me how I can get to retrieve my username and password? Also tell me what needs to be at the hostname box and the SID box. Thanks
Herbert.

You need a separately installed Oracle database to use with SQL Developer. If you have one at work, ask your DBA for the connection details. If you install one yourself, these details will become obvious.
Have fun,

How to configure Oracle Sql Developer for 9i

Hi,
We are using oracle 9i for existing application, and i am trying to connect oracle 9i through SQL developer 1.5.1, i got an error message "Unsupported Oracle Database Version".
Appreciate if any body guide me in this.
regards
Husal.

After removing dictionary statistics with dbms_stats.delete_schema_stats(ownname => 'SYS') I noticed the initial SQL Developer object list query became very slow.
Removal of dictionary statistics increased the predicted Oracle optimizer (CBO) costs. Previous SYS statistics were collected perhaps without realising the consequences.
You may wish to try dbms_stats.gather_schema_stats(ownname => 'SYS', method_opt => 'FOR ALL COLUMNS SIZE AUTO', sample_size => dbms_stats.auto_sample_size).
Recent Oracle 10G versions include a gather_dictionary_stats routine.
Suggest you try this on a development DB first.

SQL Developer Connection Problem (osx)

Hi,
I have a macbook pro with 10.5 and I installed sqldeveloper to acess a db (through a proxy). By clicking TEST I got "I/O exception: The network adapter could not establish the connection". I seems that I have a problem connecting the DB. However with the same connection configuration (username, hostname, port, password) I can connect with sqldeveloper in windows (that I also have installed in my macbook). Does anyone know what can I do? I don't want to use windows...
Thanks.

Have you created a TNS entry for your database in $ORACLE_HOME/network/admin/tnsnames.ora or using Net COnfiguration Assistant?
Every other oracle install (in a different Oracle Home from that of the Database) cannot connect directly to the database. They need a Net Services to connect.
Also set TNS_ADMIN variable to the the $ORACLE_HOME/network/admin in the wWindows environment so that all Oracle client install can see the single configuration.

Sql developer connection problem.

I got this as an error when making a new connection. what should i do?
the error is "the network adapter could not able to establish the connection"

Can you ping the server where the database is located? If not, that's a deal breaker.
After you get past that, you'll want to confirm that the SID or SERVICE you have defined in your connection is being serviced by a listener on the server. TNSPing can be used to confirm that from your machine if you have the Oracle Client installed.
If you have a local DBA or other experienced Oracle user, they might be able to help you.

Oracle sql developer issue...

Hi,
I am using "Oracle Sql Developer" to access the database.I am not able to see any existing table when click on "Tables" in the object browser.But i am able to query the table.
Can some one tell me how can make oracle sql developer tool to show the objects.
Thanks.

Hi,
Did you create the table after creating a connection? If yes, you can probably try a disconnect (right click on the connection and choose) and then connect again (or click on the refresh icon). A
By the way, there is a dedicated forum for [SQL Developer|http://forums.oracle.com/forums/forum.jspa?forumID=260] . You might want to post this question there, if it hasn't resolved by the steps I gave.
