Networking And Gateways :: Connecting A Client To Oracle?
Aug 15, 2010
Im trying to connect a benchmarking application (benchmark factory) from my windows 32bit laptop to Oracle on my linux desktop.
When connecting I am supplying the following details: (im getting the error: ORA 12170 : TNS connect timeout occurred)
User/Schema : matt
Password: ****
Host: 192.168.1.9
Port: 1521
SID: orcl
Connect as : SysDBA
Connect Using: Instant Client (selected from a drop down)
----------------------------------------------------
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 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
connecting two oracle database in two different server.I installed Oracle 10g XE in both system.Both system act as Server.I need to connect both server using database link concept.
how to use the tnsnames,ora and listener.ora file for connecting both system.
Connecting Oracle to SQL Server via database link.
I am trying to connect from Oracle 10G to a SQL Server database. I have looked at the manual and i will admit that i am finding the documentation quite difficult to follow. There seems to be several options to use but none of the documentation describe how each option works.
As an example, i have been given the following information on the database i need to connect to (i.e. the SQL Server database)
- Username - Password - Database Name [lets assume the database name is data_extract]
Note: In listener.ora, i only added the last SID_DESC entry. I then went on and created the database link as shown below
create database link sqlservdb using 'sqlserver.db';
When i try to access a table i get the following error
sqlplus> select * from TESTTABLE@sqlservdb; select * from TESTTABLE@sqlservdb * ERROR at line 1: ORA-28545: error diagnosed by Net8 when connecting to an agent Unable to retrieve text of NETWORK/NCR message 65535 ORA-02063: preceding 2 lines from ORASQLSERVER
A couple of things i am not sure of:
- Where do i specify the username and password to access the sql server from the oracle db to the sql server db
- Having read around on the internet, i can see some people refering to a DSN datasource. I am told that the information that i have is all i need. Is this correct or do i need something else?
- The sid i specified in inithsodbc.ora and tnsnames.ora is actually the sql server database. Is this correct?
I don't believe it is using the TNSNAMES.ora entry for this, because when I take it out of there it still connects. I create a 10.1.0.5 database and copied the tables,etc to there. But I'm having problem connecting, getting "ORA-12154:TNS Could not resolve service name". Tried the following:
I new to this, but my guess is the other entry had the full path name..and this SERVICE_NAME does not. But then again I don't believe it looks at the TNSNAMES file. This NJZTEST is the 2nd instance on the NJZAINETTEST machine.
I have recently installed Oracle Express 10g Server on my local PC. I can successfully connect to this while bypassing the TNSNAMES from SQLTools, I can't however connect to this from Forms 10g or while using SQLTools with TNSNAMES. How do I configure my TNS names to use this server?
I am facing difficulty in connecting Oracle 10g client to Oracle 10g database. Both the machines are in windows xp with service pack-2. The following observations are made in server machine
1. The loopback test of the server is successful. 2. One net service name created in the server end. 3. Database connection is successful with above service name. 4. tnsping <server ip address> is successful
# This file is actually generated by netca. But if customers choose to # install "Software Only", this file wont exist and without the native # authentication, they will not be able to connect to the database on NT.

i got to find out the users hostname who are connecting to database through remote,i tried with v$session bt it is showing null values in the terminal column.how to find out ?
I was trying to connect to oracle 10g database from oracle 10g client. But unable to do so.
i am able to tnsping the db from client but unable to estatblish sqlplus connection. I get ORA-28547 error when i issue the command sqlplus hr/***@db1. ORA-1560 when the command sqlplus hr/*** is issued.
I have mentioned the listener and tnsnames.ora files
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 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?
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.
Database is up and running and client machines able to do TNSPING; But when users try to connect the database thro SQL DEVELOPER, they are getting below information:
your database connection has been reset. Any pending transactions or session state has been lost.in the database server, SQLNET.ORA reads as below:
> more sqlnet.ora AUTOMATIC_IPC = ON names.directory_path = (TNSNAMES,EZCONNECT) names.default_domain = world name.default_zone = world sqlnet.expire_time = 15sqlnet expire time shows 15 min.
normally this error willbe suppressed if user tried after some time. But now we get this error for more than 2 hrs.
We are using Oracle 10g on linux 64 bit, client is on XP, using Oracle sql developer to connect to database through vpn, we have only allowed access to 1521 port of database
Client is frequently disconnecting
Initially client connected, then start disconnecting after 20 minutes.
Client side sqlnet.ora has following entry SQLNET.AUTHENTICATION_SERVICES = (NTS)

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 have installed Oracle 10g in Windows XP which is in 'VMware' as guest OS. share the procedure if we can connect to the oracle installed in Guest OS from the main operating system.
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.
"instantclient" already downloaded and configured as below :
dll files like "oci.dll,... etc" are here : C:Oracleinstantclientinstantclient_11_2 Created both tnsnames.ora & listener.ora are here : C:Oracleinstantclient etworkadmin
And did the below in user/system variables :
User Variables : ========= TNS_ADMIN with value "C:Oracleinstantclient etworkadmin"
System Variables : =========== TNS_ADMIN with value "C:Oracleinstantclient etworkadmin" ORACLE_HOME with value "C:Oracleinstantclient" Path edited and added this value "C:Oracleinstantclientinstantclient_11_2"
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 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.
