Cant change the connection with the database

its strange... i have 2 databases for same schema with diferent users ...in one i dont have data and the other i have data...... i have created 2 database connection in my connection navigator..... the strange thing is:
when i change the connection of the application module to the database that doesnt have data and i run the page there are always appear data wich are in my first database.... eventhought i have change the connection... but if i use bussiness component browser to test it .... i dont get data for those views... in fact this is how this should be...... how is this possible ?
i am using different faces-config.xml files..... is this connection saved in some files and i should change it by hand?

Hi Me_J,
Here is the bc4j from one of my application module: <?xml version = '1.0' encoding = 'UTF-8'?>
<BC4JConfig>
   <AppModuleConfigBag>
      <AppModuleConfig name="MyAppModuleLocal">
         <DeployPlatform>LOCAL</DeployPlatform>
         <JDBCDataSource>jdbc/MyConnectionDS</JDBCDataSource>
         <jbo.project>DataModel</jbo.project>
         <AppModuleJndiName>dfly.datamodel.entities.MyAppModule</AppModuleJndiName>
         <java.naming.factory.initial>oracle.jbo.common.JboInitialContextFactory</java.naming.factory.initial>
         <ApplicationName>dfly.datamodel.entities.MyAppModule</ApplicationName>
      </AppModuleConfig>
   </AppModuleConfigBag>
</BC4JConfig>You should have something similar. If you have applied security on your application, you could have a "data-sources.xml" file. Assume to have correctly change this file too.
Instead of using two different connections, i prefer to use only one and changing the parameters when i need to access a different source. You just need to remake and rebuild your project for make your changes effective.
Hope that help,
Good luck,
Tif

How to change a connection with the database in Runtime?

How to change a connection with the database in Runtime?
My connection was made using ADF Business component (ApplicationModule).
ADF Swing.
JDeveloper Studio 11.1.1.4.0.

When deploying ADF applications with database connection, you should be using JDBC data sources configured in the weblogic server.
You could change the JDBC data sources to a different DB instance or location - by changing the JDBC data source and restarting the weblogic server.
For more details, check

Hyper-V could not replicate changes for virtual machine 'machinename': The connection with the server was terminated abnormally (0x00002EFE).

I have a 3 node cluster that has replica setup to replicate to another cluster off-site.
Suddenly one of the servers is not replicating with the error:
Hyper-V could not replicate changes for virtual machine 'machinename': The connection with the server was terminated abnormally (0x00002EFE). (Virtual Machine ID CC0FD4CC-F9B7-4C68-ABE8-B7D52A87899F)
All other servers are replicating fine so there cannot be a permissions or connectivity issue between the 2 clusters.
This server has 2TB of data so I'd rather not have to start the replication again.
Does anyone have any pointers?
Thanks.

Hi drensta,
Based on my knowledge , "hyper-v replica broker " is needed for failover cluster replica .
Here is a link for "Why is the "Hyper-V Replica Broker" required?"

Thanks for reply, I have posted Service Request to Oracle Metalink and finally resolve the issue, they suggested me the following solution( a note has also been posted in Knowledge Base no. 871016.1 )

Increase the Keepalive time in webcache to a higher value

Listener refused the connection with the following error: ORA-12500

Hi,
We had had some difficulties with our portal lately. All of a sudden portlets failed and started givin error messages all over our webpages.
I tried to login to EM Console to try and restart Portal OC4J and got this error
An error was encountered while loading page. An error occurred when attempting to connect to the Database.
Resolution:
Make sure that the database and listener are up.
If the database is up, make sure that the OracleAS Repository API files ias.properties and iasschema.xml are correctly configured.
If necessary, use the EM Console to reconfigure the host, user name and password associated with the database

Hi,
[oracle@myoramachine ~]$ oerr ora 12505
12505, 00000, "TNS:listener does not currently know of SID given 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 SID for an instance (usually a database instance) 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 instances are currently known by the listener by executing:
//    lsnrctl services <listener name>
// - Check that the SID parameter in the connect descriptor specifies
//    an instance known by the listener.
// - Check for an event in the listener.log file.
[oracle@myoramachine ~]$1. Check lsnrctl services <listener name>
2. Check tnsping output:
tnsping MYORACLE
3. Check connectivity to the machine where your Oracle Server resides to port ( I assume 1521):
telnet <your_machine> 1521
4. In case you're not able to connect to the Oracle Server - I'd investigate it in a few directions:
     - network infrastructure problem
     - some disturbing process(es) / virus(es) on Oracle Server itself
     - firewall issue
Good luck!

The Connection descriptor used by the client was:

I m using the following datasource in struts.config.xml file:\
<data-source type="org.apache.commons.dbcp.BasicDataSource" key="msgds">
and I m using a DatasourcePlugin class which implements Plugin :
In this I m writing like this:
public void init(ActionServlet actionServlet, ApplicationConfig config) throws ServletException {
ServletContext context = actionServlet.getServletContext();
DataSource datasource = actionServlet.findDataSource("msgds");
ontext.setAttribute("ds", datasource);
And in each Action i m using like this:
ServletContext context = getServlet().getServletContext();
DataSource ds= (DataSource) context.getAttribute("ds");
Connection con = ds.getConnection();
and in finally i m closing the connection. Now Can somebody tell what could be the possible error. How can I use Connection Pooling Using JNDI, Commons dbcp.
If Somebody have the code snippet, plz send it,
Thanks in Advance...

Hello,
OC4J is the core component of the OracleAS, the J2EE/WebService container where you deploy your J2EE applications
So you are using OC4J when deploying your application.
Do you know what release and the type pf topology that you are using when deploying your application? (stand alone OC4J -run from java command- or a managed OracleAS run from an opmnctl command...)

Internet Download error message: the connection with the server has been reset

With an WRT54GS v6 firmware v 1.50.9 on Windows XP SP2 with Internet Explorer 7, Intel wireless internal adaptor w/ 802.11b, I was getting the error message "The connection with the server has been reset" when downloading most anything from the Internet. My IP address would then be reset and download would be interrupted. To resolve, I turned off the WZC (Wireless Zero Configuration) Services, and this seems to correct the problem.
Control Panel > Admin Tools > Services > Wireless Zero Configuration > Disable
Hopes this helps.

Hi!
Im using Windows 7.... I tried looking for the Wireless Config - but it isn't in the Services options!
So, what can I do now?
Thanx

Has anyone else had this problem, if yes how do i resolve it???
