DirectAccess Network Adapter Error

I have setup DirectAccess on 2012R2, and keep getting the following error after setting up the configuration.
Error:
DirectAccess clients cannot connect to all resources on the corporate network.
Causes:
Routes required to send packets to the corporate network have not
been published on adapter Ethernet. These routes are required for
remote clients to reach the corporate network.
Resolution:
Publish the IPv6 routes on the network adapter that connects the server to the corporate network.
I have set this up multiple times before and never had an error like this. I can't figure out how to resolve it. This is on a small network with a DC, File Server, DA server running as VMs on hyper-v 2012R2.

Hi,
Here are some things you might try:
1. Make sure your listener is actually up: lsnrctl status
2. Try using the fully qualified host name (including domain) if you are not already doing so.
3. Even if you uninstalled Studio, you might check your Windows ENV settings. (Not really sure, but to be safe!)
That is, for [3], make sure any references to Studio have been removed from the PATH variable. You might also check to make sure either to remove any ORACLE_HOME variable, or at least make sure it makes no reference to the prior Studio installation.

OSR installation throws network adapter error

Has anybody experienced this error during service registry installation? The errors say that it could not create a database connection because the network adapter could not establish a connection. This is the SQL exception that is being thrown when I try to install. I have the loop back adapter configured. I am trying to install this in Vista. I already have database and SOA suite installed.

Hi,
May be u can try testing it with an agent which is hosted in your remote desktop?
Thanks,

Hi Allan,
Thanks for your quick reply.
I have checked in OWB\Locations\Database\Oracle\Location\DB Connectors and also in Control Center\Location\Connectors,seems like there is no connectors created.
Do you have any other suggestions?
Also i analyzed the UpdateControlCenter.sql in that
select value into v_connectiontype from cmpstringpropertyvalue_v where logicalname = 'CMPLocation_ConnectionType' and propertyowner = v_elementid;
the qry returns 'SQL*NET'.
Any workaround for these???
Please reply.

If you're sure that you have a Broadcom BCM57xx
device installed in the machine, then you should have a look at
"prtconf -pv" output, locate the Ethernet device, and check the
"vendor-id" / "device-id" property for the NIC.
If the Broadcom device is compatible with Sun's "bge" driver, you
can try to install an addition driver binding entry for your device,
using the update_drv(1M) command
update_drv -a -i '"pciVVVV,DDDD"' bge(where VVVV and DDDD is the pci vendor / device id found in
prtconf -pv output).

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.

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:

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

SQL Developer: Failure -Test failed: IO Error: Network Adapter No Conn

SQL Developer: Failure -Test failed: IO Error: The Network Adapter could not establish the connection
Hi,
and sorry this is a really common questions and yes I did do a search, but I don't understand it.
First let me just tell you that Oracle 11g is installed on my second laptop on the same Network.
Secondly I can connect to the Database using Oracle SQL Developer on the laptop Oracle 11g is installed on.
The problem is I want to connect to the database on my main Laptop.
I put in the correct details Hostname 192.168.0.8 ( this is the laptop oracle is installed and running on)
Port 1521
SID dbarudu
****** YES I HAVE PORT FORWARDED
****** YES I HAVE ALLOWED 1521 on the FIREWALL
****** YES I HAVE EVEN SWITCHED OFF THE FIREWALL
Now one more thing you should know ... I don't know nothing about Oracle Servers ok.... so I have just installed Oracle 11g Enterprise and thought done it should be working now.
I just need to use oracle db for a project.
So keep in mind I am a total noob and terms like TNSPING etc mean absolutely nothing to me.
So please help, but help with step by step guide on how to get Oracle to let me have access from another computer.

If the Listener is working, then you should not get the error SQL-Developer error you are reporting.
The listener typically runs using the hostname and port 1521. This means it opens tcp port 1521 on all IP addresses of that platform.
The database server by default will register itself with the local listener. Thus the listener will know the database SID, the database services, whether there are dispatchers to support shared server connections and so on.
The client side needs simply to specify 3 pieces of data to connect:
- the IP of the database server
- the tcp port of the listener
- a database identifier (such as Oracle SID or service name) to connect to
It is really that simple.
If this does not work, the problem falls into 2 broad categories:
a) incorrect installation and configuration of the Oracle software (the out-of-the-box install works unless messed up)
b) some kind of networking issue
To troubleshoot any problem means reducing the complexity of the problem, eliminating multiple moving parts and focusing on specific ones, in order to isolate the problem.
For your problem, this will go something as follows:
- does the listener run? (check if the service is running and whether tcp connections are accepted on the listener port - telnet can be used for the latter)
- does the database successfully registers itself with the listener? (check the services command of the listener and relevant db initialisation parameters)
- does a local TNS (tcp network) connection work on that server? (use SQL*Plus and test on that platform client-server connectivity via tcp to the listener)
- does the client platform have connectivity with the server platform? (use ICMP and telnet to test)
- repeat the TNS test on the client platform using the same working TNS tested on the server platform
Do not use JDBC to test the connection - keep it simple and use sqlplus and the standard Oracle Call Interface (OCI). A full client version of the OCI plus sqlplus can be downloaded under the Oracle InstantClient downloads.
Finally - if you expect to simply install and use Oracle, then use the correct version. Oracle Express Edition aka Oracle XE. Installs and works out-of-the-box. The only manual config change to make is (as far as I recall) to run the listener on all IP addresses of that platform. And this required editing the listener.ora file, changing the HOST parameter and restarting the listener.
Also keep in mind that you have not presented an Oracle error code and Oracle error message. But a client application error message. And that message is pretty much meaningless - it does not point to a specific Oracle networking or Oracle server problem. To diagnose that, we expect a TNS or ORA error number.

Java.sql.SQLException: IO Error: The Network Adapter could not establish...

Hi,
I know that there are a lot of threads with this error, but I don't know how to solve my situation yet.
I'm trying to access to the database via JDBC, and the driver return the following error:

- My oracle database is up and I can access to it with locally with TOAD
- I can do TELNET localhost 1521 in the server that has the DB installed
- I can do a successful ping from the client computer to the oracle server
- There aren't any firewalls between the client and the server.
- When I try to do TELNET <IP Address> 1521 from the client computer to the oracle DB Server, the connection could not be opened
- I tryed to do a TELNET to another port where I have another service, and the result has been successful. So the problem is related with the port 1521...
I don't have any knowledge about database administration, so I don't know what to do to solve this.
Can you help me please?

java.sql.SQLException: IO Error: The Network Adapter could not establish the connectionThis preposterous error message is Oracle's way of saying either 'Connection refused' or 'Connection timeout' or 'no route to host' or 'unknown host'. However because of the stupidity of making up their own message instead of giving the original exception, it is impossible to say which. The pretentious wording is also stupid: network adapters don't create connections. TCP/IP stacks do that.
As to your problem, either there is no such host, no route to the host, nothing listening at the IP:port you specified, or there is a firewall in the way. And that includes a possible Windows firewall on the server host itself.

AnyConnect installation issues - Network Adapter is not created - cannot find any error?

I am a contractor with a Federal Agency that just swithed to using Cisco AnyConnect for VPN access. I am about the only person with this installation issue, that I know of. When installing the AnyConnect client on a Windows 7 machine running a 3.X msi install - the expected Cisco NewWork Adapter is not created in Network connections as I would expect. I have turned off Firewall services, I've turned off SQL services, Citrix, etc. But nothing I have tried allows this to install correctly.
When I attempt to use the AnyConnect VPN client and login the the remote service - I receive the
The VPN client driver has encountered an problem. Please restart your computer or device, then try again.
I have attempted the driver database fix suggested online - BUT it didn't correct the problem because I think my problem is in the initial setup, although I cannot find and error in the Windows/inf/setupapi.app.log and setupapi.dev.log that would suggest there is an driver problem.
The DART logs are a bit cryptic, but nothing stands out that would give me any idea as to what might be blocking the creating of the Network adapter the VPN Client would use to connect to the remote network.
Can anyone here point me in the right direction - I am not receiving help from configuration management - their solution is to format my entire computer and rebuild it which will cost me weeks of time and I have a deadline looming in Feburary.
Thank you!

"The Network Adapter could not establish the connection" error

I'm intermittently able to connect into my development database from my PC. When I'm not able to connect in, I'm getting a message of "The Network Adapter could not establish the connection" regardless of the client I'm connecting with. This database is located on a server and is Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production. I have a local install of WebLogic Server that has generated the error message when attempting to start. I have also received the message in SQL Developer and SQL Plus.
As I stated in my first sentence, the issue is intermittent this morning - sometimes I can connect and sometimes I can't...
I've been working successfully in this database for months now without this issue, so I'm guessing that the database itself is having issues, but I'm not a DBA...just a measly developer trying to use the database ;)
Are there good questions for me to ask of my DBA or ways to discover what could be causing the issue? Or, is there something I can do on my machine to get around this?

!. Suggest contacting your DBAs first, but Id suggest seeing if the connection is up.
when you get it, check the tns connection. open a dos window
firstly tnsping the database name
tnsping <SID of database from your tnsnames.ora>
then try ping the machine where that SID is
then try telnet to the port of the database thats in your tnsnames.ora
telnet <host> <port>
if you get a blank screen then you know at least the listener is up and running on that machine. CTRL + [ will back you out of the telnet session.
