Networking And Gateways :: Connecting Two ORACLE Servers
Aug 8, 2006
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
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) ----------------------------------------------------
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 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 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 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 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 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.
----------------------------------------------------------------- TNSLSNR for 32-bit Windows: Version 10.2.0.1.0 - Production System parameter file is D:oracleproduct10.2.0db_1 etworkadminlistener.or a Log messages written to D:oracleproduct10.2.0db_1

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?
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?
Recently I came across a problem that 'ORACLE Client Side Disconnect every 5mins in app server' these days.
Situation: We have 3 APP servers, which was configured the same OS and ORACLE Client version and 1 DB server. 2 app servers ORACLE Client Side Disconnect every 5mins.but it's ok in another App server.
1. both Oracle SQL PLUS and PLSQL have this problem. 2. SQLNET.EXPIRE_TIME is the same for 3 APP 3. 2 APP server are virtual machine and balance server 3. APP servers : OS: 2003 Server ORACLE 9i DB server : ORACLE 11g 4. I don't think it's DB server problem because one App server hasn't this problem
I am currently using Oracle 10.2.0.1 version, in a single PC (test server) and MS-Access (2003) in it.
I was trying to use the logic of HS ODBC connectivity, but when i try to select the table from the MS-Access i am getting the following error.
"ORA-12154: TNS:could not resolve the connect identifier specified".
to create the successful connection between the MS-ACCESS and ORACLE. I just need to read some data from MS-ACCESS on a monthly base from a particular table.
I need to created DB link between oracle (10g on linux) and mysql 5.0 to configure a job to fetch data after every hour. I need solution that does not involve:
But i do a lot of work-arounds to make sure the installation does not make corrupt my OracleAgent,OracleService and OracleDataGatherer. If i just let the installation do its thing i have problems with my libraries, and can't start anything.
The errors are : Procedure entry point 'BlaBla' could not be located in the Dynamic Link library 'AnyName'.
I notice that i have 2 versions of the libraries in OracleHomeBIN (one version 8, one version 11). The programs that start the OracleAgent,Service and DataGatherer call the old libraries but expect to find values that can be found only in new libraries.
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?
I'm trying to connect Oracle 11g database from Oracle 9i database, by creating dblink on Oracle 9i database. But my session got hang while i perform this. Here i'm giving the steps i followed on my both the database. Here Oracle 9i database is my source db and Oracle 11g is my target db.
Following steps/setting on Oralce 11g Database
SQL> SHOW PARAMETER SEC_CASE_SENSITIVE_LOGON
NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ sec_case_sensitive_logon boolean TRUE
SQL> alter user SSA identified by SSA;
User altered.
Password File recreted on Oracle 11g Database Server
DROP DATABASE LINK "SSA11G.SSA_DB1.WBTEA.COM"; CREATE DATABASE LINK "SSA11G.SSA_DB1.WBTEA.COM" CONNECT TO SSA IDENTIFIED BY SSA USING 'DEVDATA.DEV11G';
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

I have created two database one for production and another one for test.I created both database in shared_server mode(by using dbca),after than I did not change anything.My problem is when i connect to test database from outside lan through static ip its working well,but when i connect to production database which is not connected. I checked and compared two databases,then I find there are some changes in dispatcher and mts_ dispatcher parameters.And I used this query to check the shared_server status,
ie.select * from v$shared_server,
the output of this query is attached with this post.
