post results from the following two OS commands:

lsnrctl status

lsnrctl service

Since every connection request to the listener gets logged, listener.log file will contain a line with 12505 as status code.

*This line contains valuable debugging details. So post this line & surrounding lines.*

for additional debugging suggestions read the URL below:

http://edstevensdba.wordpress.com/2011/03/19/ora-12514/

[oracle@localhost ~]$ oerr ora 12505

12505, 00000, "TNS:listener does not currently know of SID given in connect descriptor"

// *Cause: The listener received a request to establish a connection to a

// database or other service. The connect descriptor received by the listener

// specified a SID for an instance (usually a database instance) that either

// has not yet dynamically registered with the listener or has not been

// statically configured for the listener. This may be a temporary condition

// such as after the listener has started, but before the database instance

// has registered with the listener.

// *Action:

// - Wait a moment and try to connect a second time.

// - Check which instances are currently known by the listener by executing:

// lsnrctl services <listener name>

// - Check that the SID parameter in the connect descriptor specifies

// an instance known by the listener.

// - Check for an event in the listener.log file.

So now you have to ask yourself, "why doesn't my listener know about 'orcl'?"

Two reasons come immediately to mind:

1) this listener isn't on the server where your 'orcl' instance is running

2) this listener IS on the same server, but the 'orcle' instance is NOT running

3) this listener IS on the same server, the 'orcle' instance IS running, but an incorrectly set LOCAL_LISTENER parameter prevents it from registering with the listener.

BTW, your listener is configured to listen on IP address 127.0.0.1. This absolutely guarantees that it will never receive a connection request that originates from any other box.

I am running this code on my Laptop.

What really annoys me is that this code snippet worked before.I formatted my system and re-installed Oracle and now this exception.

I am sorry if this sounds stupid.

So is the database running on your laptop? On the native OS - not a virtual machine?

You've been given several clues ... I've not seen anything indicating you've actually followed up on them.

sb92075

is OS Service for the database been started & is now running?

is the database itself been started & is now online?

sandeep.c

The database is installed on the native OS.All its services are running and as mentioned before I am able to login as user scott and sysdba.

I was going through your wordpress blog.and was looking at my tnsnames.ora file,the content given is as belows

# tnsnames.ora Network Configuration File: D:\app\Sandeep\product\11.2.0\dbhome_1\network\admin\tnsnames.ora

# Generated by Oracle configuration tools.

ORACLR_CONNECTION_DATA =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

)

(CONNECT_DATA =

(SID = CLRExtProc)

(PRESENTATION = RO)

)

ORCL =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = orcl)

)

Still stuck

sb92075

the output from

lsnrctl status

would show any running database; which it does not for YOU!

see example from my system below

[oracle@localhost ~]$ lsnrctl status

I can see that all Oracle services has started by doing a services.msc.(particularly OracleServiceORCL)

But when I run this from sqlplus as scott/Scott123

CONNECT scott/Scott123@orcl

"TNS:listener does not currently know of SID given in connect descriptor"

Is that what you meant ? Looks like I am missing something basic.What do you suggest ?

earlier in this thread you posted the results from

lsnrctl status

that was run on your system.

It does NOT show "Service "orcl" has 1 instance(s)." since it does not know about any database named "orcl"

& this is consistent with the error message.

open a Command Window & do as below

lsnrctl stop

cd D:\app\Sandeep\product\11.2.0\dbhome_1\network\admin\

ren listener.ora listener.ora.sav

lsnrctl start

lsnrctl status

# wait 60+ seconds before proceeding

lsnrctl service

COPY the results from above then PASTE all back here

a) I tried "lsnrctl stop" but it said

LSNRCTL for 64-bit Windows: Version 11.2.0.1.0 - Production on 06-NOV-2013 02:45

:44

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521)))

TNS-01190: The user is not authorized to execute the requested listener command

So, I tried stopping it from services.msc,i.e,stopping the service "OracleOraDb11g_home1TNSListener"

b) ren listener.ora listener.ora.sav => Gave me Access denied error.

So,I renamed the file manually.

lsnrctl status gave me the following output.

I can now see "Instance "orcl", status READY, has 1 handler(s) for this service..."

I tried running my Java code and now I have the OP...

Connected to the Oracle database...

Now,all what I did was stopping the listener service,renaming the listener.ora file and starting the service again.

Please correct me if I am wrong at any point.

sb92075

previously listener.ora contained bad or incorrect data.

by eliminating the file which is NOT required to start or use the listener, the default values provided success.
