How to connect to remote database

Hi experts,
i want to connect with another database in our network what are all the steps i need to follow? i just confused with listener.ora and tnsnames.ora. waiting for your ideas.....

The database listener is the process that is configured via the listener.ora file. The administrator of the other database should have configured a listener for that database.
On the client machine, you'll need to configure a tnsnames.ora entry unless you are using Oracle Names, Oracle Internet Directory, EZConnect syntax, or something like JDBC to connect. The administrator of the other database should be able to give you a tnsnames entry for connecting to his (or her) database.

Connect to remote database

hello
i am souvik kundu . i am using tomcat web server that is in india . Through this web server i want to connect oracle data base that is in philipins(remote) .pls tell me the code or procedure how i connect to remote data base ?????????

Dear Souvik,
The physical location of the database is not of big concern while working with the java programs.
U might be aware how to connect to remote database from ur localmachine if u have databaseclient(Oracle client for example) installed in ur system.
U need to have a tnsnames.ora file to resolve the database.
An entry in the tnsnames.ora file will lokk like the following
name=( description = (address = ( host =ipnumber ) ( protocol = tcp ) (port = some port number ))(connect_data = (sid=sidname)))
Here the sidname is very important
If u have this description in the tnsnames file , then u can connect to any oracle machine in the world with the valid userid and password.
al this is another part of the story , but now our concern is to make ur tomcat application capable of conencting to remote database
there are two ways that i suggest u
1) Explicitly make connections to the remote database from withing ur java program as follows
String userId="scott";
String passWord = "tiger";
String url = "jdbc:oracle:thin:@ipnumber:portnumber:sidname";
String driver = "oracle.judbc.OracleDriver";
//This is very important
try{
Class.forName( driver );
Connection con = DriverManager.getConnection ( url,userId,passWord );
}catch(){
Here the difference is that if ur using a local database u need not to give the ip number and portnumber combination
Note:check whether ur network can contact to the destination by running the command at command prompt
> tnsping ipnumber
If tns ping doesnt work then u cant contact the remote database.
2) Use tomcat admin console screen to set up a datasource and give required information as I provided above,
Then u can obtain the connection frm the datasource.

Connection to remote database failed

I have configured the cman.ora file and changed the connection
string for the java applet, but I encountered the error
"The NT Adapter could not establish the connection" when I tried
to connect to remote database from JDev2.0(beta).
Any ideas of what are the possible causes for this?
At the cman.ora file, the setting are:
cman = (ADDRESS_LIST=
(ADDRESS=(PROTOCOL=tcp)(HOST=<web_host_ip>)(PORT=1610))
(ADDRESS=(PROTOCOL=tcp)(HOST=<db_host_ip>)(PORT=1521))
cman_profile = (parameter_list=
(MAXIMUM_RELAYS=1024)
(LOG_LEVEL=1)
(TRACING=yes)
(RELAY_STATISTICS=yes)
(SHOW_TNS_INFO=yes)
(USE_ASYNC_CALL=yes)
(AUTHENTICATION_LEVEL=0)
At the java applet the connection statement are:
DriverManager.registerDriver (new
oracle.jdbc.driver.OracleDriver());
Connection conn =
DriverManager.getConnection ("jdbc:oracle:thin:" +
"@(description=(address_list=" +
"(address=(protocol=tcp)(host=<web_host_ip>)(port=1610))" +
"(address=(protocol=tcp)(host=<db_host_ip>)(port=1521)))" +
"(source_route=yes)" +
"(connect_data=(sid=<orasid>)))", "<user>", "<id>");
The error at the dos prompt running from JDev2 are:

I am able to connect to the remote database using SQL*plus but
does it means it is using CMAN connection?
How do I test the CMAN connection from SQL*plus? Any example for
me to follow?

pls help me, how to connect to it
i have the ip address,port address,sid,username and password of the database
is there any difference in the actual code of database connection
plss help

Hi,
There is a particular example with MS SQL 2000 in thread http://forum.java.sun.com/thread.jspa?threadID=608314
In the given example you just need to change the database URL and the JDBC driver. Just examine the code a little bit.
Also you may wish to visit the SUN's JDBC tutorial on http://java.sun.com/docs/books/tutorial/jdbc/

How to connect to Oracle database from webdynprojava application

Hi
How to connect to Oracle database from webdynprojava application. where can we provide the code to connect to database.?
Thank You.

Hi,
You need to create Java Bean model. The bean is a typical java bean with default constructor, getter and setter. You can have additional methods for query etc. The attributes in the class will be your model node and attributes.
However you need to configure the connection and create JNDI using visual administrator before writing the code.
You can also consider writing Session EJB with oracle and using them in WD.

Connecting to remote database (idle) with Password File Authentication

Hi all,
I was wondering if it's possible to connect to a remote database that is shut down (idle instance) as sys user with sysdba privileges? In the book Oracle - All in One on page 210 in the section - Operating System and Password File Authentication it says:
Connection with operating system or password file authentication is always possible, no matter what state the instance and database are in, and is necessary to issue STARTUP or SHUTDOWN commands.
Above indicates that it's possible but I'm unable to do so.
I managed to connect to remote database that was in nomount mode (see below for details).
When I first tried to connect to a remote database (idle instance) using password file authentication it was giving following error:
sqlplus sys@ORCL as sysdbaSQL*Plus: Release 11.2.0.3.0 Production on Fri Dec 21 13:59:28 2012

I have all necessairly entries in tnsnames.ora on my local host.
Also I have no problems when connecting as sys user with sysdba when the DB is open but can't get it work on an idle instance.
I know that I can use operating system authentication but want to know if there is a mistake in the book or I'm doing something wrong.

Primary and standby cannot talk to each other currently through the listener:
ORA-16664: unable to receive the result from a database
Cause: During execution of a command, a database in the Data Guard broker
configuration failed to return a result.
Action: Check Data Guard broker logs for the details of the failure. Fix any
possible network problems and try the command again.
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
Cause: The listener received a request to establish a connection to a database or other service. The connect descriptor received by the listener specified a service name for a service (usually a database service) that either has not yet dynamically registered with the listener or has not been statically configured for the listener. This may be a temporary condition such as after the listener has started, but before the database instance has registered with the listener.
Action: - Wait a moment and try to connect a second time.
- Check which services are currently known by the listener by executing: lsnrctl services <listener name>
- Check that the SERVICE_NAME parameter in the connect descriptor of the net service name used specifies a service known by the listener.
- If an easy connect naming connect identifier was used, check that the service name specified is a service known by the listener.
- Check for an event in the listener.log file.

How do connect to Historical Databases?

Hi,
please explain me what is Historical databases?
Can u tell me how to connect to Historical databases? can we download these Database servers from net?
- senthil

Hi Senthil,
You can try for RTXHDB (RTX Historical Database).
RTX provide secured relational databases for LAN and WAN network.
Often the use of relational database, or transaction-oriented technology, for off process historical LAN/WAN database applications, and doing unconventional operations on data.
As an example, It is in this area of off process historical data warehousing and retrieval that the RTXHDB (RTX Historical Database) system excels. RTXHDB processes and stores a massive flow of data for LAN/WAN database applications, which then can be retrieved with a great deal of speed and quickly turned into useful information for the PC user.
You can check following links for more information.

The only way to know whether the remote database is up (and whether the network between the two databases is up and whether the remote database's listener is up and whether the password configured in the database link is correct and whether the local TNS alias is correct, etc) would be to actually run a query against the remote database over the database link. In other words, the way to figure out whether the link is up is to let the job run and catch & handle exceptions when there are problems.
By default, a job scheduled via DBMS_JOB will automatically reschedule itself if there is an unhandled exception by geometrically backing off (it waits 1 minute after the first failure, 2 minutes after the second, 4, 8, 16, 32 minutes, etc until it's marked as broken after 16 failures). You could, of course, catch appropriate exceptions and handle them in a reasonable fashion and manually reschedule jobs at intervals that make more sense for your particular job.

How can i connect to remote database from netbeans

Hi,
I have got MySQL database server installed and running on a different machine. Is there any way to connect and browse database remotely using netbeans 5.5?
I have added connector/driver for that database. i can connect and browse the database with host: "localhost" and port number. But when i specified the ip address of that machine, it gives me error.
Can anyone help please.
cheers.

well, its not working in App server either.
In App server admin console, on that connection pool if i define servername as "localhost", it works fine. If i change it to the remote machine's ip address, then it doesn't work.
Any idea will be appreciated.
cheers.

How Forms 6i could connect to remote database 9i

AOA,
Our company has different sites located in different cities. In the main office we have developed many modules using Oracle 9i and Developer 6i and our data is highly confidential.
In all remote sites our modules are running by standalone. Now we want to connect our remote sites with our main Database.
What will be the options available to make highly secured connection between our sites and main office.
In our city different ISPs are available who can provide dedicated IP access, DSL and VPN.
If anybody has any experience please let us know.

In the itvimsapp server execute the command
emctl status dbconsole
and see the name server and port, for example:
===================================
[oracle@bddesa oracle]$ emctl status dbconsole
TZ set to America/Guayaquil
Oracle Enterprise Manager 10g Database Control Release 10.1.0.3.0
Copyright (c) 1996, 2004 Oracle Corporation. All rights reserved.
http://bddesa:5500/em/console/aboutApplication
Oracle Enterprise Manager 10g is running.
===================================
If the server is running you can connect with the sentence
http://bddesa:5500/em or http://192.168.1.186:5500/em
I hope this help
