Connecting to remote database using Connector/J

I'm new to JDBC so be gentle.
Basically i'm trying to connect to a remote database from my own computer (client to server). As far as I know i'm doing everything correctly. Am I correct in thinking that Connector/J is native to JDK versions 1.2 and up? Which in turn means that I don't have to install any other drivers as long as i have the JDK installed?
public void loadDriver() {
        try {
            Class.forName("com.mysql.jdbc.Driver").newInstance();
        catch (Exception ex) {
            System.out.println("Cannot load driver");
    }Ok, here's my loadDriver() method which isn't working and causes nothing else to work because it doesn't work. I'm getting the information from the mySQL documentation here: http://dev.mysql.com/doc/connector/j/en/cj-registering-with-driver-manager.html
Not sure what's going wrong here, help would be very much appreciated
Regards

Ok i ended up putting the correct .jar file into the correct dir finally. It seems as though some of the instructions in the documentation are incorrect.
Ok i am now able to load the driver but the connection keeps timing out when trying to connect to the database.
At the moment i'm trying the following:
con = DriverManager.getConnection("jdbc:mysql://kezzer.co.uk/db", "username", "password");But it doesn't seem to be working. Obviously i'm not using those exact strings for the database, username and password but that's the format it's currently in. Any ideas?

  • Connecting to Remote Database using Debian w/Oracle XE

    Hello.
    I have managed to install Oracle XE on a Debian box.
    I am trying to connect to a remote server located on my network.
    I am using the following connection string:
    # sqlplus <User>/<Password>@'(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=<IP>)(PORT=1521)))(CONNECT_DATA=(SID=<SID>)))'
    However, I was given both a SID and a Service_name.
    I tried connecting with both.
    Is it possible to parametrize both? I checked and the remote server is up, and that is the existing port.
    Thanks a lot!

    SQL*Plus: Release 11.2.0.1.0 Production
    Copyright (c) 1982, 2009, Oracle.  All rights reserved.
    Use SQL*Plus to execute SQL, PL/SQL and SQL*Plus statements.
    Usage 1: sqlplus -H | -V
        -H             Displays the SQL*Plus version and the
                 usage help.
        -V             Displays the SQL*Plus version.
    Usage 2: sqlplus [ [<option>] [{logon | /nolog}] [<start>] ]
      <option> is: [-C <version>] [-L] [-M "<options>"] [-R <level>] [-S]
        -C <version>   Sets the compatibility of affected commands to the
                 version specified by <version>.  The version has
                 the form "x.y[.z]".     For example, -C 10.2.0
        -L             Attempts to log on just once, instead of
                 reprompting on error.
        -M "<options>" Sets automatic HTML markup of output.  The options
                 have the form:
                 HTML [ON|OFF] [HEAD text] [BODY text] [TABLE text]
                 [ENTMAP {ON|OFF}] [SPOOL {ON|OFF}] [PRE[FORMAT] {ON|OFF}]
        -R <level>        Sets restricted mode to disable SQL*Plus commands
                 that interact with the file system.     The level can
                 be 1, 2 or 3.  The most restrictive is -R 3 which
                 disables all user commands interacting with the
                 file system.
        -S             Sets silent mode which suppresses the display of
                 the SQL*Plus banner, prompts, and echoing of
                 commands.
      <logon> is: {<username>[/<password>][@<connect_identifier>] | / }
               [AS {SYSDBA | SYSOPER | SYSASM}] [EDITION=value]
        Specifies the database account username, password and connect
        identifier for the database connection.  Without a connect
        identifier, SQL*Plus connects to the default database.
        The AS SYSDBA, AS SYSOPER and AS SYSASM  options are database
        administration privileges.
        <connect_identifier> can be in the form of Net Service Name
        or Easy Connect.
          @[<net_service_name> | [//]Host[:Port]/<service_name>]
         <net_service_name> is a simple name for a service that resolves
         to a connect descriptor.
         Example: Connect to database using Net Service Name and the
               database net service name is ORCL.
            sqlplus myusername/mypassword@ORCL
         Host specifies the host name or IP address of the database
         server computer.
         Port specifies the listening port on the database server.
         <service_name> specifies the service name of the database you
         want to access.
         Example: Connect to database using Easy Connect and the
               Service name is ORCL.
            sqlplus myusername/mypassword@Host/ORCL
        The /NOLOG option starts SQL*Plus without connecting to a
        database.
        The EDITION specifies the value for Session Edition.
      <start> is: @<URL>|<filename>[.<ext>] [<parameter> ...]
        Runs the specified SQL*Plus script from a web server (URL) or the
        local file system (filename.ext) with specified parameters that
        will be assigned to substitution variables in the script.
    When SQL*Plus starts, and after CONNECT commands, the site profile
    (e.g. $ORACLE_HOME/sqlplus/admin/glogin.sql) and the user profile
    (e.g. login.sql in the working directory) are run.  The files may
    contain SQL*Plus commands.
    Refer to the SQL*Plus User's Guide and Reference for more information.

  • Connect to remote database using ODBC

    I am new to TimesTen and I would like some help connecting to remote timesten database using ODBC.
    I followed all the instructions in the manual to setup (like logical server and all). but, when I try to connect using "connect dsn=myRemoteDSN" command, it does not work. It gives me this error: 7001: User authentication failed
    It is asking me for username and password but I dont know how to setup username and password. Looked all over the internet and I could not find any relevant posts. I have already tried "unchecking" the authentication, but it still asks me for username and password.

    thanks for your help. I did not realize that that I turned on ACL. creating a user and then granting the needed permissions did the trick.
    I now have another problem. I use windows platform and .NET 2.0 (C#) to connect to remote timesten database. The driver provided by timesten (as part of installation) does not seem to support ADO.NET. I get "driver does not support this function" exception when I try to insert data into a table. Ironically, it does insert the data successfully, but still generates the exception. I looked at various forums.. everyone seems to have the same problem, but have not had any solution yet?
    Could you let me know if you encountered this issue before and how you might have resolved it?
    Many thanks

  • Not able to connect to remote MySQL database using Connector/J

    I have an application that uses a connection pool for database access.
    It is initialized with this context.xml entry:
    The db server is running on port 3307.
         <Resource name="jdbc/DB" auth="Container"
                        type="javax.sql.DataSource" username="un" password="pw"
                        removeAbandoned="true" removeAbandonedTimeout="60" logAbandoned="true"
                        driverClassName="com.mysql.jdbc.Driver"
                        url="jdbc:mysql://localhost:3307/myDB"
                        maxActive="8" maxIdle="4"/>Now after starting the context, I can see I have a connection to my database using the MySQL Administrator. So I know I am connecting.
    The problem is, when I try to query any table in the db, I get this message:
    java.sql.SQLException
    : Table myDB.TABLE_NAME' doesn't exist
    at com.mysql.jdbc.MysqlIO.checkErrorPacket(
    MysqlIO.java:2921) ...
    I know it does in fact exist because I am looking at it. And the code I am using works perfectly fine as long as it is running on a local db server.
    Any ideas?

    I know it does in fact exist because I am looking at
    it. And the code I am using works perfectly fine as
    long as it is running on a local db server.
    Any ideas?Yes two.
    I am bit unclear about the last thing you said... you are testing with two different servers or two different clients?
    Anyway here are the possibilities off the top of my head.
    1) Some sort of security issue. Surrounding who and from where users can connect to the database in question.
    2) Case sensitivity problem. On Windows MYSQl makes all it's table names lower case only. Then it onlu supports the correct case to access them.
    For example
    CREATE TABLE TestMe
    Can then only be accessed with
    SELECT * FROM testme
    Not TestMe.
    This appears to vary with version but i have seen this issue before.

  • Remote connection to a database using TOAD, but without Oracle db on PC

    I want to connect to a remote database using TOAD from my PC but without having to install Oracle database on my PC.
    Is it possible?
    If yes, where do I enter the database IP address & port number?
    I am using TOAD Freeware version 8.5.0.50g
    (I want to achieve the exact thing with TOAD as it can be done with "OraCmd" program.)

    How did you create your tns entry? Manually or via netca?
    If netca is not used, I would recommend to delete the old tns entry from tnsnames.ora file manually and add the same entry back via netca utility.
    PartA.
    1) Make sure listener is up (for example on the server 192.168.0.33 you are trying to connect) before you start netca. Most probably it is on 1521 port unless you changed it.
    Assuming your server on *NIX:
    $ ps -ef |grep lsnr
    the above command will give you all the listeners which are up and running.
    If listener is not up, bring it up.
    $ lsnrctl start listener
    the above command will start listener called "LISTENER" on default port 1521. Ignore this if the listener is already up.
    PartB
    Assuming your client machine is on Windows,
    1) start --> run --> cmd --> netca
    2) You will see "Oracle Net Configuaration Assistant: Welcome" window. --> next
    3) Pick the 3rd radio button "Local Net Service Name Configuartion" --> next
    4) Pick the "ADD" button. --> next
    5) Provide the service name. (It is usually database name). Assuming my database name is FCMAT, I will give FCMAT --> next
    6) Pick "TCP" --> next
    6) Instead of the hostname, add the ip address of the host (for example 192.168.0.33 and
    "Use the standard port of 1521"--> next
    7) "Yes, perform a test" (this is why you have to have the listener up to test it) -->next
    8) It will fail as it doesn't have any password. Click on "Change Login" and provide the SYSTEM password and click "OK". If listener is up on the server and password is right and there are no connectivity issues going on, test will SUCCEED. --> next
    9) Here you will provide Net Service Name. You can give whatever you like to give here but usually giving instance name will help. AGain, I will give FCMAT. -->
    10) Click "NO" to configure another net service name. --> next
    11) click "Finish"
    The above steps will create a tnsnames.ora entry similar to this.
    FCMAT =
    (DESCRIPTION =
    (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.33)(PORT = 1521))
    (CONNECT_DATA =
    (SERVICE_NAME = fcmat)
    Part3
    1) start your sqlplus utility
    2) provide username system
    3) provide password
    4) provide FCMAT in host string.
    and you should be able to connect via sqlplus and TOAD.
    If you are still getting the error, please provide us the exact error.

    P.S. tnsnames.ora / listener.ora / sqlnet.ora can be found $ORACLE_HOME/network/admin directory.

    Is that possible to create view at remote database using dblink? Following syntax returns error
    create view ViewName@DbLinkDame (ColumnName) as

    "ORA-00905:missing keyword"
    Is that possible at all?
    And particulary - is that possible when remote database is MSSQL and I am using heterogeneous services?
    I really appreciate your help
    best regards
    Wojtek
    Edited by: wojpik on Oct 21, 2009 3:59 AMI doubt you would be able to fire any ddl through database link. You have to connect to remote database to run any ddl even if it is Oracle or some other database.

    I have configured the cman.ora file and changed the connection

  • 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:

    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.

  • Connect to remote database is incorrect

    There is a database server with two running Oracle instances. Their SIDs are "SID1" and "SID2".
    I'm trying to establish a remote connect from an another host.
    tnsnames.ora:
    ArchiveDB =
    (DESCRIPTION =
    (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP) (HOST = 172.16.82.11)(PORT = 1521))
    (CONNECT_DATA =
    (SID = SID2)
    But when I try to connect to the remote database using: sqlplus user/password@ArchiveDB, it says that login/password are incorrect, but if I use credentials for the instance (database, to be more precisely) "SID1", it works. That's why I decided that it tries to connect to SID1, not SID2. Why? Any Ideas?
    Thanks in advance.

    Hi,
    As per your scenario, you specified either the problem must persist in your tnsnames.ora or listener point to the ORACLE Home..!!
    it says that login/password are incorrect
    Second thing is that try to check whether required is used to connect the DB, I mean correct user is utilized for login
    Coming to remote Login, check whether oracle password file is maintained and REMOTE_LOGIN_ PASSWORDFILE is exclusive is setted properly

  • 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.
    Regards
    mahi

  • Unable to connect to Oracle Database using Oracle Sql developer 2.1.1.64

    Hi Everyone,
    I am searching for some help regarding my problem with Oracle connectivity. I have installed Oracle 11g release 2 on my Windows XP Professional Laptop. For a few days after installation i could connect to the Oracle database with the SYSTEM account using Oracle SQL developer ( installed on the same Laptop) but now i am unable to do so.It gives me this annoying message:
    An error was encountered performing the required operation  Got a minus one from read call .Vendor code 0
    However i am able to connect using Sql Plus by supplying the username SYSTEM and the corresponding password.
    My TNSNAMES .ora file is as follows:

    I am new to Oracle and so i need someone in this forum who can help me resolve this problem. Also i even tried connecting to the database using Toad 10.5.0.41. It give me the following error:
    ORA 12537 : TNS Connection closed
    Thanks for your patience and help in advance.

  • Connection to multiple databases using a single EJB

    How can I connect to multiple Databases (using @PersistenceContext) using an EJB?
    Did I need to connect various Entity Managers corresponding to the each database and simply send my Queries?
    I am using Glassfish Application Server
    Netbeans IDE
    Java Derby Database
    Oracle Database
    Java Persistence API
    Thanks in Advance

    Yes, you need a persistence context and thus entity manager per database. Depending on what you want to achieve you may also need to go to the next level in your skill set and learn all about distributed transactions.
