Networking And Gateways :: Using Oracle Connection Manager
Dec 4, 2011
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?
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.
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.

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 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.
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 ?)";
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.
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.
TNS-12518: TNS:listener could not hand off client connection TNS-12571: TNS:packet writer failure TNS-12560: TNS:protocol adapter error TNS-00530: Protocol adapter error Linux Error: 104: Connection reset by peer
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've a problem with Oracle Connection Manager and I've read the Oracle topic about it at URL.....but it doesn't work well...This is an image describes the diagram I want to configure URL.....
The IP for each machine is Database Server : 192.168.0.150 Proxy Server : 192.168.0.153 client : 192.168.0.159
ORA-12154: could not resolve the connect identifier specified: where I actually define my DB service (orcl) in the tnsname.ora...The output is showen here URL.....
I have an Access DB which I'm using to connect to an Oracle DB at work. There are several Oracle DB's that I can connect to using Access but this one I'm not able to connect to. I get the Oracle error ORA-25153 Temporary Table Space is empty.
I don't have the ability to make changes to the Oracle DB only to read and query.
We're deploying a new product release however this build uses Oracle 11G. We want to perform a side by side install for testing purposes. These are low usage systems so installing another Oracle build will not hinder the system.
We intend to test for a couple of weeks and migrate data, then uninstall the 10G. I'm in the process of installing 11G now, the 10G is up and running. I don't want to impact the 10G install. I'm installing 11G in /home/oracle/oracle11G directory. I would like to use 1 Listener.ora file. I've broken down the install bellow.
10G SID "processing" Oracle home /home/oracle/oracle10g /mnt/Oracle/Oracle10GData /mnt/Oracle/OracleRedoLog
11G SID "processing11G" Oracle home /home/oracle/oracle11g /mnt/Oracle/Oracle11GData /mnt/Oracle/Oracle11GRedoLog
Do I need to specify the databasename for Processing2? Also the front end boxes (managers) are two different servers so Processingweb1 and processingweb2.
I want to connect ORACLE-11gR2 that is on linux with an MS sql server. DO i need to use some third party drivers like easy soft ? Can i configure the database gateway without any third party drivers ?
Secondly if my oracle is on linux, can i configure the gateway on a seperate windows machine(that will connect to linux oracle and ms sql server) as i have found the gateway installation setup only for windows version.
i want to online my oracle 10g database but when i make connection string then i don't know what the port i set. I set default port 1521 but it not work on client site .
I know how to create a database link between two oracle servers, but problem is that SID is same for both servers, Is there any other way to connect two servers without using only 'SID' ..here are TNSNAMES.ORA FILE i HAVE
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.

One of my MOD_PLSQL based Oracle APEX Application is running on the web. I have almost 1000 web users to access the Application where at least 250-300 users are always on line. In Oracle EM web interface When run ADDM I see suggestions "Investigate the cause of SQL*Net more data to client" or something like this. and I am getting complains about poor server response. Here are my configuration of the system:
Database Server Host: DBServer (Oracle Database 10.2.0.3) HTTP Server Host: OraHTTP (Oracle Companion CD 10g)
DADS.conf HTTP Server configuration MOD_PLSQL database access for web clients.
How can I increase database connection performance?
