    Check your Oracle Net configuration (tnsnames, listener)

  • The network adapter could not establish the connection after hostname chang

    hi all,
    my computer name and ip address are changed after it is moved to another location in a local lan network. however, when i tried to connect my database in oralce 11g (enterprise edition) after, i got this error "the network adapter could not establish the connection" (in sql developer)
    and "Configuring database with database control requires a listener to be configured in the current oracle home. You need run Netca to configure a listener before you can proceed. Otherwise you may choose to continue with database control" (in dbca when i tried to create a new database). i also cannot access my database in OEM becasue it is still refering to old host name with this error message "Firefox can't establish a connection to the server at...". i changed the old host name to the new host name in files of listener.ora, listener1212114PM3012.bak, tnsnames.ora, and tnsnames1212114PM3012.bak in folder 'product\11.2.0\dbhome_2\NETWORK\ADMIN'. but it didn't work. can anybody pls tell me what do i need to do to fix the problem. i don't want to reinstall my oracle again because i've done a lot of works already in oracle. thanks in advance.

    Hi. This is definitely an oracle-only problem, so you should simplify the problem
    down to a small standalone program using the oracle thin driver to make a connection.
    Once you get this to work, weblogic will also be able to do it. Make sure that
    when you try to have weblogic succeed after you can do it with oracle code only,
    that the driver you used to succeed with, is ahead of any weblogic jars in
    the server classpath. Note that we ship a classes12.zip in our packaging, but
    Oracle has since released a newer one (with the same name!) that has some bugs
    fixed. Make sure the later one is the one the JVM will pick up.

  • HOW TO RESOLVE(Test failed: The Network Adapter could not establish the connection)

    Hii
    I want to create new databse as sysdba in jdev.I followed the steps as given in
    Oracle JDeveloper 11g Release 2 Tutorials - Designing and Building Database Tables
    In step 7 create database user and database connection, I am not able to do that and getting the error
    (Test failed: The Network Adapter could not establish the connection).
    Please help me.

    Hi,
    Could you please provide all value you pass to the connection properties on the connection creation panel? First of all, you should choose "Generic JDBC" as the connection type in order to use BDB SQL JDBC driver.
    Regards,
    Cindy

  • "The Network Adapter could not establish the connection" on RAC databases

    I am posting what solved our situation here, in case it helps others:
    We have RAC databases that use SCAN, but also use their Local_Listener ports (because we could not go completely to SCAN due to our applications).
    For some reason, 11.1 Grid Control could see instances if we added them separately, but if we tried to connect to the database & view the performance, it would error out with "The Network Adapter could not establish the connection".
    We had to fix it by manually setting the connect string in every instance and database in the OEM Setup to the non-SCAN VIP/Ports.
    Hopefully this saves someone else hours & hours of troubleshooting. (I know, the day after Grid Control 12 comes out. SOOO helpful. :P )

    java.sql.SQLException: The Network Adapter could not establish the connectionWhere is the Oracle error? I hate this - s/w like Java suppressing the underlying error codes and messages. Just how the hell can one diagnose an error when not knowing exactly what it is? There should be a TNS error code and message.
    From the info you've given, one can only guess. And the following guess is as good as any. Load balancing is requested. Likely your RAC db services are registered on both static and virtual IPs - as the listeners are running listener 1521/tcp end points on both.
    This means the client can get a redirect to connect to a specific listener on a specific IP - and this includes the static IPs. The listener usually passes hostnames (as that is what is configured). If the client cannot resolve that static hostname to an IP, it cannot correct.
    So make sure that the client can resolve both virtual and static hostnames of the RAC - not just the virtual ones.
    If you're client is Windows, update the c:\windows\system32\drivers\etc\hosts file - alternatively register the hostnames with the local DNS.

  • Connection Pooling : Network Adapter could not establish the connection

    Hi,
    We have a client-server application wherein the server has a pooled connection to an Oracle 10i database. The application is developed in Java and we are using Oracle OracleConnectionCacheImpl API to manage the connection pooling( DYNAMIC pooling with a pool size of 5 and we are using ojdbc14.jar)
    On certain occasions when activity is extremely high, the server attemtps to retrieve around 2 million datasets/records. The connection pool runs out of connections and we get the following error :

    This is happens in Production and despite our exhaustive efforts,we have been unable to reproduce it in our Testing environment so far.
    A large number of login attempts are seen in the Oracle login monitoring table, around 50,000 but we dont think that should be an issue. At the time, when this problem occurs, there are other processes making connection to the DB without any issues. Also, after sometime, the connection is restored and no exceptions are thrown.
    Any insight into how we could simulate,resolve or monitor this issue would be greatly appreciated.
    Thanks,

    Hi. This a long-known issue, and is caused by the DBMS listener's incoming
    request buffer becoming overloaded by many simultaneous connection
    requests. It will fail some of them. I have seen this with a simple java
    program that calls Driver.connect() identically 20 times in a tight loop.
    Some of the calls will fail in this way, while others will succeed. The
    solution BEA's pool has, is to have a delay option to have the thread
    sleep a bit (half-second to a secod or so) between successive connection
    requests. After that, don't close connections until they're broken. Keep
    them and re-use them.

    Hi,
    according to the message, the database is not accessible. This can be because the database is down or the database connect information points e.g. to a wrong port

  • Io exception: The Network Adapter could not establish the connection

    Hi All,
    I run tomcat and connect to Oracle fine, both on the same machine.
    I also run some batch processes daily and they often run without problems. The batch processes lots of selects and updates/inserts onto Oracle.
    These tend to work fine, but sometimes when they run I get
    java.sql.SQLException: Io exception: The Network Adapter could not establish the connection
    So a batch process will be running doing lots of selects and updates then it just decides it had enough and throws this error each time it tries to connect. Meanwhile tomcat continues to run fine through the same TNS listener, but subsequent batch jobs fail to connect.I normally have to restart the TNS Listener.
    I connect through the same class whether connecting through Tomcat or from the batch process with this:
    public static Connection getConnection(String caller) throws SQLException{
    try{
    Connection con;
    if (standalone){
    try{Class.forName(driver);}catch(ClassNotFoundException e){}
    con=DriverManager.getConnection(url,user,password);
    return con;
    }else{
    if (ds==null)initialiseContext();
    con=ds.getConnection();
    return con;
    }catch(SQLException e){
    ds=null;
    logger.debug("Problem in DBAccess.getConnection()...");
    logger.debug(e.getMessage());
    e.printStackTrace();
    throw e;
    I specifiy params such as MaxIdle with Tomcat using the xml config but not when its standalone - could this be affecting it?
    Any idea?
    Thanks.

    Oracle should be able to handle lots of connections no problem, I agree, and it is through tomcat.
    Yet the exception that you get says that it isn't. Oracle, for example, on a single box shouldn't be able to handle 100,000 simultaneous connections.
    I would be very surprised if it couldn't handle 1,000. And if there was an issue at that point it would be a resource bound issue, like CPU (on the single box) rather than connections.
    You suggested licensing issues?I believe at one time, not necessarily now, the Oracle server would be sold such that it limited the number of simultenous connections. This could have been a relatively low number. There are quite a few assumptions in that - the major one would be it is based on my faulty memory and second would be that it was years ago.
    By the way you are not running this on a unix variant system without redoing the kernel limits to set up for a server system right?

    For starters, you make sure that there is even the possibility of a network connection between your client machine and the machine hosting the "remote system".  What happens when, on the client machine, you issue a 'ping <ip address of remote system>'?

  • Jdbc. The Network Adapter could not establish the connection. Help Please!!

    I've found several responses over this issue, but none works for me.
    I'm trying to setup a simple jdbc connection from a simple program.
    Platform:
    Fedora Core 4 (FC4) on AMD 64 bits
    Java 1.4.2_04 (64 bits)
    ORacle 10g or Oracle 9.2.0.4 (none works);
    Tips:
    - I can't connect to a remote server, nor to a local server
    - I can connect using SQLplus
    - TNSPing works fine
    - Listener it's up
    - my connection string is jdbc:oracle:thin:user/name@host:port:sid
    - Also try jdbc:oracle:thin:user/name@//host:port/sid
    - I'v tryied with classes12.jar, odbj14.jar
    - my hostname it's ok.
    I've monitored ip traffic on remote computer. While using TNSPING I detect activity. While using jdbc, no.
    Please, any idea??

    Thanks for your reply.
    To your questions:
    - I´v tried both IP, host, and even host.domain
    - I can connect from remote workstation using toad, and from local using sqlplus.
    - I can´t connect via jdbc.
    Folowing:
    A) my sample code
    B) the stack trace
    C) the listener status (from my 9i server. Also tryied another servr with 10g)
    when I call this program, I´ve tried severl connection strings:
    jdbc:oracle:thin:user/pass@sdd51:1521:ebf
    jdbc:oracle:thin:user/pass@:sdd51.sdd.com.ar:1521:ebf
    jdbc:oracle:thin:user/pass@:10.10.10.51:1521:ebf
    also try the other sintax:
    jdbc:oracle:thin:user/pass@//sdd51:1521/ebf
    In the classpath, I´tryied:
    clasess12.jar
    ojdbc14.jar
    nls_charset12.jar

  • Top Link error 17002 The Network Adapter could not establish the connection

    I have installed an application developped in an another environnement.
    I have created the database schema in my own database.
    I have created a database connection to this schema.
    I have reconciled the schema using this connection (so the database and the connection are available and correct from jdeveloper)
    I have updated the Mapping to use the new connection and new generated the mapping status report without any errors
    and i still have this error ! The Network Adapter could not establish the connection when i access any jsp document containing data from the database.
    I check and recheck everything and all is correct ... sure something is wrong somewhere ... where is the question ...

    Sorry I think you didn't read the thread or you read it too fast !
    I'm not a beginner and I know what the problem is but all the settings are correct in jdev and the database and the listener are running ... i'm able to browse the tables, seeing data reconciling objects with the database connection referenced in the top link descriptor
    It seem that top link is using something else and i don't understand from where it took the connection description.

  • SQL Developer Connection Error: Status : Failure -Test failed: IO Error: The Network Adapter could not establish the connection

    Hi, I'm running the following setup:
    Mac OS X 10.8.4
    Virtual Box 4.2.16 r86992
    Oracle Developer Days (don't know the version, just downloaded it)
    SQL Developer 3.2.20.09
    Networking is host-only, I tried bridged but that doesn't make a difference for the problem at hand. I can ping my virtual box just fine, telnet to port 1521 looks good too:
    $ ping 192.168.56.101
    PING 192.168.56.101 (192.168.56.101): 56 data bytes

    Connected to 192.168.56.101.

    asdf
    Connection closed by foreign host.
    When I create a new connection with sql developer, with the same hostname / IP (192.168.56.101), Port 1521 (didn't change that) and SID orcl, basic connection type, it can't even connect, throwing the error mentioned in the subject:
    Status : Failure -Test failed: IO Error: The Network Adapter could not establish the connection
    I have looked at various threads in the forums here but I'm still stymied why the connection seems to be ok, yet sql developer has problems with it. If I create an ssh tunnel so sql developer only has to connect to localhost it works:
    ssh -L 1521:192.168.56.101:1521 -l oracle 192.168.56.101

    Hi Ali,
    This may be of varoius reasons..
    Is the database that you are connecting on the same PC?
    You have specified Hostname: localhost.
    If not please replace it with the IP of that server.
    Else please check whether the database listener is started or not. if not please start the listener.
    Check the SID by tnsping command.
    Hope this will help you..
    Thanks
    Ashok
