Disable "Estimated network bandwidth on one of the connections" check

I have several Windows clients that hang at applying computer settings when starting up. All computers that show this behavior have 2 network adapters. One is the physical adapter another is a virtual adapter created by 3rd party software. Virtual Network
adapter always stays enabled (even if you disable it, it comes right back to the enabled state) and has an APIPA address assigned to it. The OS sees the adapter in connected state and attempts to estimate the network bandwidth on that connection,
but since no traffic is being passed through on this link it's forced to wait for the time out, which causes the delay. So the question is, how do you exclude a specific network adapter from being checked for bandwidth at the OS start
up?
Thanks

Hi,
>>One is the physical adapter another is a virtual adapter created by 3rd party software. Virtual Network adapter always stays enabled (even if you disable it, it comes right back to the enabled state
Based on the description, it's recommended that we contact the vendor support of the software to see if they can help disable the virtual adapter or provide some suggestions regarding the situation.

I have two Macbooks at home that are connected to a Comcast Wi-Fi network modem. One of the computers has sporadic in receiving the WI-FI signal while the other is unaffected. Both have same operating system. Does anyone know a solution to this problem?

I have two Macbooks that are connected to the same Comcast Wi-Fi network modem. One of the computers has become very sporadic in receiving the WI-FI signal while the other is unaffected. Both have same operating system (10.5.8). I have restarted computer, and unplugged and retarted modem on several occassions to no avail--one still works the other inconsistent. Have spent a great deal of phone time with Comcast and they suggest acquiring latest OS. Does anyone know a solution to this problem?

This does not sound to be a router problem...You should try to uninstall and re-install the ethernet adapter/card installed in your computer...Do you have 2 Ethernet Adapter's by any chance...Check the Device Manager, Click on the Start button >>> Settings >>> Control Panel >>> Double click System, go to Hardware >>> Device manager, click on the plus'+' sign next to Network Adapters and see how many Ethernet Adapters are listed...
Also connect that computer straight to your modem and see check if you get the same message,that 'YOU ARE CONNECTED TO MORE THAN ONE NETWORK'...

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?

I got a The Network Adapter could not establish the connection..

hi guys,
i've just downloaded and installed oracle 10g express in my win 7 installation.
i've already created 2 tables and one user and everything seems to be ok.
but.. there's a but!!! i've tried to connect (using driver ojdbc14) from netbeans and i got a "The Network Adapter could not establish the connection" error.
the connection string is:
jdbc:oracle:thin:@pcs:1251:XE
(pcs is my pc's name).
what problem can be?
many thanks ;)

Failure-lo exception:The network adapter could not establish the connection

Hi All,
any one can assist me .
I installed latest SQL developer in my home laptop
I am trying to connect using my SQL developer using my database UN and PW.
It is giving the following error message
Failure-lo exception:The network adapter could not establish the connection
Thanks in advance.
Regards,
Veera Lenin

THis error usually means there is no network path to the database host, or there is a firewall in the way.
What details are you using in the connection definition?
Where is the database - on the same machine or on another machine?

Failure -lo exception: The Network Adapter could not establish the connecti

I get the following error when I attempt to connect:
Failure -lo exception: The Network Adapter could not establish the connection
I'm running 64-bit Windows XP Pro. Is that possibly an issue? I can ping the server. I am going to go now and install Oracle client software, to see whether I can tnsping and then connect from that.
The remote listener is up and running. I did check that.
What else might be the problem?

Kris,
I don't mind having to re-key connections between versions of Raptor, but if Raptor is going to save a connection that worked when I entered it, I expect that connection to work when I restart Raptor.
If you can't save a connection with just the TNS Alias, at least save it as something that works - convert it to the basic format.
Having said that - I would certainly prefer the connection to be saved as the TNS Alias if it could be. We have in the past had cases where we have modified the SID or Listener Port behind a TNS Alias to reduce downtimes during upgrades. With a centralised TNS Names file (which we have), there is only one place to update - if we are saving the full details behind the connection on every developer's PC, there is then a lot of additional places where the details need to be changed.

If it worked yesterday, but not today, that proabably means you turned off your computer between then and now.
I suspect you set up some classpath term using say a dos window that when you turned off your computer, went away.
You need to put the classpath in some configuration file such as <start><control panel><admin tools><data sources odbc>,
or add information to your tnsnames file, or add an item to your computer's PATH.

JDBC says: "The Network Adapter could not establish the connection"

Hi all! I'm trying to run a servlet that does SQL queries, but I keep getting a "The Network Adapter could not establish the connection" SQL exception on the connection attempt. Code follows.
import java.io.*;
import java.sql.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class InterpreteSQL extends HttpServlet
     public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException
          try
               Class.forName("oracle.jdbc.driver.OracleDriver");
               Connection connection=DriverManager.getConnection("jdbc:oracle:thin:@labdb.dsi.unive.it:1521:lab","[my account here]","[my password here]");
               Statement statement=connection.createStatement();
               ResultSet res=statement.executeQuery("SELECT * FROM TabellaProva");
               stampaResultSet(res,response.getWriter());
          catch (Exception e)
               response.getWriter().println(e.toString());
// stampaResultSet method here, which would just print the result set.
Of course, the bits in brackets have the actual account and password in the code. ;)
If I make a standalone program with the same code, it works fine. I'm using Tomcat 4.0.3 on a Windows 98 machine. The machine is not directly connected to the internet, but through a router. There's a firewall but it isn't blocking the program. Since the standalone version works, I suppose it's a Tomcat configuration issue.
Can anyone help?

I too had the same problem
Check out for the related services. It must be running.
One way to know about is try using SQL+ and execute some query.Thats it.

what is the problem here??
i don't have any problem yesterday.
but today i got this one.........

The Network Adapter exception is caused because:
1. The database host name or port number is wrong.
The HOST and PORT are specified when a JDBC
connection is configured.
2. The database TNSListener has not been started. The TNSListener may be started with the lsnrctl utility.
C:\>lsnrctl start

"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.

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.

HT1338 My Mac keeps Looking for Networks? The ICON in menu when clicked shows the WI- FI (in gray) ON then goes to Looking for Network again. Shutting down the connection.

My MAC keeps looking for networks? The ICON in menu bar when clicked shows the WI-FI (in grey) it keeps shuting off and disconnecting. Any Ideas???

Test after taking each of the following steps. Back up all data before making any changes.
1. Make sure the network is on the preferred list by following these instructions.
2. Follow the instructions in this support article under the heading "Symptom: The network connection drops unexpectedly."
3. Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
4. From the Location menu at the top of the Network preference pane, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.
5. Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
6. In some cases, the problem has been resolved by repairing permissions on the startup volume.
7. Reinstall OS X.

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

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

Error: The Network Adapter could not establish the connection

hi, i am using classes111.zip (the oracle 8.0.5 thin driver) with
linux and gnu jsp pages. the backend is an oracle 8.04 NT
database.
i get this error: "The Network Adapter could not establish the

problem or the db server problem. here is the code:
String driverName = "oracle.jdbc.OracleDriver";
String url = "jdbc:oracle:thin:oracle1:1541:ORCL";
String user = "demo";
String pwd = "demo";
String SQL = "";
ResultSet rs;
try

while(rs.next())
out.println(rs.getString("xx") +
rs.getString("yy"));
catch( SQLException e )
out.println("
