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.
BAM240T_EARTH =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = tcp)(HOST = 10.154.119.103)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = BAM_240T.ipdc.com)
)
)
The database name is : BAM_240T.ipdc.com
Sqlnet.ora entry is
NAMES.DIRECTORY_PATH= (TNSNAMES)
NAMES.DEFAULT_DOMAIN= ipdc.com
When I connect to server I m getting the following error.

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 ?)";
But this query is not very hard.
I am having difficulty in making the 32 bit Oracle client connection to an existing 64 bit DB. The 64 bit SQL*Plus will connect just fine, but when trying to configure the 32 bit client I can never get a successful TEST of the connection. It always returns "No TNS Listener". I have tried several things, but may be way off base. To name a couple ...
1) Stopped the 64 bit listener so my 32 bit listener can use Port 1521 ... no success
2) Tried naming the 32 bit listener to LISTENER32 to not conflict with the original LISTENER name ... no success
If there is a documented way to make this work, I would surely like to be pointed to the "how to" of this item. I need this as a commercial application I have that connects to the DB requires the 32 bit client.
I have client and database on same machine, when I will connect to the instance , it will use IPC, suppose If I will use connection string then which process will handle this request?
View 2 Replies View RelatedI 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.
View 13 Replies View Relatedi have 2 instances (one on Oracle 11g and the otherone Mssql) i was asked to make a link between both.
btw i need excecute a procedure from Oracle against Mssql tables.
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.
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.
setup the connection between oracle developer and database.
i found the file called tnsnames.ora however, i cant open it. i dont know if i need to choose a program to open it or download extension for it.
My production database server is cloned for test environnement . I kept the same name of SID for both environnement but on different hosts.

1) I put attention that TNS write events into its log in too big frequency: ~ 10 time in second. I see that it is for every connection, but I assume that this no too good to performance.Is there some way to tell to TNS not to write event for every connection but only for errors?
2) May I to remove alert.log of DB? Or DB will make me problems with this?
3) How can I tell to my client connect directly to my instance rather than during TNS?
I have Oracle RAC 11g running on Red Hat 4 64 bit.
I´m working with Oracle 9.2.0 / HP-UX and I need to configure two different listeners for the same server using different IP address.
View 12 Replies View RelatedMy client get the error Ora-12514 when he tries to connect to the db.Well;
1) we restart the services: "OracleServiceOrcl" and listener but nothing changes
2) We restart the server and nothing changes
3) We checked the dump and he was done on March,26th. No db export yesterday. Is there any link with the clock change of this week-end (location of the server: France)?
4) The lsnrctl services listener command run successfully but it doesn't mention the instance ORCL.
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 have installed on my local machine the Ora 11 XE server and the client. Its okay. I can logon from the OAS normally.
However, when I try to connect from my Php application, the messages that comes is: 'ORA-12154: TNS:could not resolve service name'.
I am having 11.2.0.1.0 database with windows2k3 OS. For ORA-609 error i have started server side tracing by adding TRACE_LEVEL_SERVER=16,TRACE_LEVEL_DIRECOTRY=D:TRACE,and DIAG_ADR_ENABLED=off in sqlnet.ora file and i reload the listener.
Now i want to stop tracing so i have tried TRACE_LEVEL_SERVER=off but it wouldnot work. After that i remove TRACE_LEVEL_SERVER=16,TRACE_LEVEL_DIRECOTRY=D:TRACE from sqlnet.ora file and reload the listener but trace file generation is going on D:TRACE. stop server side tracing.
Currently we are loading data from oracle to sql server through oracle 11g gateway. during running scripts most of the queries takes a long time to complete. Because of this performance issue, we want to configure oracle golden gate to move data from oracle to sqlserver. whats the difference between oracle gateway & oracle golden gate? both are performing same functionality?
