I am having Oracle 11g (Release 11.2.0.2.0) running on Windows Server 2007 SP2. I am trying to connect to this server from my system using SQL Plus command prompt. (Dedicated - redirect (client and server are on different computers)
I am getting an error: TNS-12518: TNS:listener could not hand off client connection.
When I checked the listener log in the server machine, these were the errors: TNS-12518: TNS:listener could not hand off client connection TNS-12560: TNS:protocol adapter error TNS-00530: Protocol adapter error 32-bit Windows Error: 203: Unknown error

ERROR: ORA-12518: TNS:listener could not hand off client connection
Below is alertlog entry
Completed: alter database open Thu Apr 04 17:06:19 2013 db_recovery_file_dest_size of 4096 MB is 0.00% used. This is a user-specified limit on the amount of space that will be used by this
ODBC--call failed.TNS:listener was not given the SID in CONNECT_DATA (#12504)
TNSname sets the SID. SQL*Plus is able to connect from the client Windows XP Proff using the same name. Access, on the same client, uses the same Oracle driver to connect successfully to other Oracle databases. These other databases show equal tnsname (different name and SID...)
ODBC Data Source Administrator configures the database and the test connection is successful.
Cannot set up a link from Access to the Oracle database. At some point, I have created a new Access database and it did let me connect, view the list of tables, and set up links to several tables, but the next day I could not open any of the tables and the complain was: ODBC--connection to 'MYDB' failed.
It seems that SQL*Plus passes correctly the SID from the TNSname but ODBC, when invoked from Access, does not. Yet, ODBC does it right for other databases.
When i connect from client to server the client looks up for the host address and port number in tnsnames.ora and connect to it via listener.ora in server.Where does pga and sga come into picture here?
Also what is the role of sqlnet.ora in client?What will happen if i specify a different port for the instance in tnsnames.ora and listener.ora?
I have one query related to database connection from server to client.I have one database in the server and I want to connect from client.I set the tnsnames in client system as follows.
I am using oracle 11.2.0 in linux platform.i have created a listener for the asm database. and i am using non default port of 1525 whenever i go for lsnrctl>status always shows for the port 1521. i don't want the default port 1521 and i have changed the local listener as listener1 with port 1525 protool tcp in spfile and registered with the asm database.Is there any option to change the default listener as listener1.
also,everytime when i give lsnrctl>show current_listener it is showing "listener"
i have set the current-listener to listener1 and save_config listener1 and reloaded.After exit and enter lsnrctl>status it will show for port 1521 When i attempt to start listener1 every time. it will prompt listener1 is already running.
In one of our RAC envrionment, we have more than 15 databases in a server running in AIX Operating system.the Listener file I am able to find only one entry (SID). But while trying to execute lsnrctl status it displays all the 15 SIDs in the list hosted in the ser ver. Not sure how it works?
As we created another one new database in the database, where i need to add this SID in the listener.ora file to reload the listener.
I was trying to connect to a remote database from my client machine. Client machine runs a jsp code to connect to the database and execute a query. I have got oracle jdbc on my machine but still unable to connect to the database.
When checked in Google, i found that oracle connection manager has to be used to connect to the database from jdbc if the web server and database reside on different physical servers. But couldn't gather any further information regarding download and installation.
I do not have oracle connection manager on my system. I read in internet that it is shipped along with oracle 11g software. But i am not sure if that was the case in earlier version as well.
My question is where should i install oracle connection manager? (on database server or client machine) and is it possible to download and install only the connection manager as a stand alone so that i can connect to database from application?
I am getting the error TNS-12537. In the SQLnet.ora file, if no IP Address is listed everything works fine and the listener starts without any issue. But one of the Security requirements we have is, we need to list all the client IP address on the SQLNet.ora file. I checked the Windows Firewall services and it is disabled.

I am facing ora - 12537 TNS connection closed issue while I am trying to login into database.I have installed Oracle database 11g on windows 7 premium OS.
Which parameters are required in init file for 'Dynamic Listener Registration'? (for default port/ protocol). I understand that Local_listener is required only if we are using not default protocol, port.
Also which cases we need listener.ora file? I understand we need it for 'Duplicate Database' using RMAN as well as for 'Data Guard'. what else will need it?
I am having a problem getting my listener to start.

When i configure a listener using net manager,if found that the red text box in the picture can fill "the value of the global name " or "the value of the service_names".
I am done with my configuration for oracle HS to connect to SQLserver. When I tried to start my listener, it is giving the following errors.

I just installed oracle 11g on a fresh RHEL 5.2 installation on virtual box.
The database is up, but the listener (LISTENER) hangs after a minute from starting it, and then any lsnrctl command just hangs without showing any error messages, when I restart the virtual machine and then start the DB and listener, it works for a minute and it hangs again!

Should i have to do some changes in sqlnet.ora for overriding the default settings?
Is it possible to bind an Oracle Listener on 2 different interfaces on the same host?
My initial situation: I've set up a new VLAN in eth1.8 on our database server. There are 2 Oracle instances on this host. One instance was set up for the new VLAN, this works fine. The other listener stayed in the old network, because an other customer also needs to access this instance.
Now the customer wo was set up for 2 new VLAN can't access the other instance listenig on the interface eth0.
In short I have the following setup: customer1: eth0 customer2: eth1.8 (VLAN)
listener1: LST1 listener2: LST2
SSID1: SID1 SSID2: SID2
listener1 is listening on eth0 for SID1 listener2 is listening on eth1.8 for SID2 This works fine.
Now customer2 needs to access SID1, which is configured on eth0, but customer2 is configured for eth1.8
So I need a listener for SID2, that is configured for both interfaces eth0 AND eth1.8.
i have created a listener for my db and register the service to it some 2 years back now i have checked it and it display as follows

now i have stop and then restart but same status? so how can i manually register it again or anyother solution as i cant run netmgr
I have a database up and running (including listener) on machine A. From that machine, everything seems fine. However, when I try to connect to it from another machine (say, machine B) on the network, the connection cannot be established (exact message: connection to database failed: The Network adapter cannot establish the connection).
I can successfully ping machine A from machine B. The machine A db is a default install (ORCL).
Is it possible the DB listener is not configured properly to connect to remote clients? On machine B, I have oracle tools such as SQLPLUS, Oracle Net Manager, and Net Configuration Assistant.
ORA-12518 Tns: Listener does not currently know of service
from application server using client 10g to connect our database.This problem happens only in application server and we tried from another server we can connect to database easily but problem only in application server.
this error since TNSNAMES and network are properly hosted since there no network disconnection betwwen database server and application server.
I have a JBOSS aplication server connect to database. When I tested on local, everything was ok. But when i test on real system , have a message "connection time out" on log file of app server while Oracle db still active. I viewed OEM, the system is executing the query :
"SELECT a.path songFilePath, a.BEAT beat from vp_song a, mst_my_album b "+ "where "+ "a.BEAT = b.BEAT "+ "and b.my_album_id IN "+ "(select my_album_id from (select my_album_id, ROW_NUMBER() OVER (order by my_album_id asc) "+ "R from mst_my_album where msisdn = ?) WHERE R BETWEEN ? and ?)";
when i am connecting to my database in command prompt,sql * plus editor is it successfully connecting to the database but not connecting with the oracle client OEM.
but after connecting the LAN it is not connecting and also in the case when i am connecting to the internet through the USB datacard it is not connecting with the oracle client OEM.
how can i connect to database when the LAN,USB datacard connection.
I just found out that the LISTENER I've creating with a password was with "-inherit" settings. Twice I succeeded in doing this, but it seems that it's not working when I tested it. Thus, I opted to get rid of it's listener.bak file and set the password again. Now I just can't stop it because of this error message: "TNS-01169: The listener has not recognized the password".
I've tried every passwords I made, and tried resetting it, but I'm not successful either, it's the same error message.My last option would be to restart the db Server (since the original listener.ora is already intact),
