Data-sources.xml instead of bc4j.xcfg

Please give me some direction on how I can configure my Application Module to use JNDI lookup of my data-sources.xml file instead of using the bc4j.xcfg file. I know there is a way but I need a step by step process to get this done through configuration while developing in the IDE.

Can you please tell how did you solve that. I have similar problem

903/902/BC4J can't get data-sources.xml conn pooling to work in production; help

I have several BC4J ears deployed to a 903 instance of OC4J being configured as a standalone
instance. I've had this problem since I started deploying in development on 902. So it's
some basic problem that I've not mastered.
I can't get data-sources.xml managed connection pooling to actually pool conn's. I'm wanting
to declare my jndi jdbc source connection pool in j2ee/home/config/data-sources.xml.
Have all BC4J apps get conns from this JNDI JDBC pool. I've removed all data-sources.xml from my BC4J ears,
and published the jndi jdbc source in my oc4j common data-sources.xml. I've tested that this is
the place controlling the conn URL/login passwd by commenting it out of config/data-sources.xml
and my BC4J apps then throw exceptions, can't get conn.
I've set the oc4j startup cmd line with the BC4J property to enabled connection pooling:
-Djbo.doconnectionpooling=true
symptom
Connections are created and closed. Instead of being put back into the pool managed by oc4j,
what ever BC4J is doing or my data-sources.xml is doing, the connections are just being created and
closed.
I can verify this via (solaris) lsof and netstat, where I see my oc4j instance under test load
with only 1 or 2 conns to the db box, and the ephemeral port is tumbling, meaning a new socket is
being opened for each conn. ;( grrrrrrr
Does anyone have a clue as to why this is happening?
Thanks, curt

I've run another test using local data-source.xml, that's packaged in the .ear. Still
pooling under BC4J doesn't work??
A piece of info is that the 903 oc4j release notes states that global conn pooling doesn't
work. Infering that the j2ee/home/config/data-sources.xml data sources aren't pooled or ??
I just tested so called local connection pooling, where I edited the data-sources.xml that
gets packaged in the ear, to include the min/max params and re-ran my test.
Still, the AM creates a new conn, it's to a new socket, and closes the conn when done. Causing
each conn to not be pooled, rather opened then closed to the DB box. As verified with lsof and
netstat, checking the ephemeral port # on the DB box side, always changes, meaning it's a
new socket and not an old pooled conn socket.
???? What the heck??
Surely if the AM conn check out / return code works properly, OC4J's pooling JDBC driver would
pool and not close the socket??
Has anywone gotten JDBC Datasource connections in BC4J to actually be pooled under OC4J??
Since I couldn't get this to work in my early 902 oc4j testing, and now can't get it to work
still under 903 OC4J, either it's my config or BC4J AM's code or OC4J?
Any thoughts on how to figure out what's not configed correctly or has a bug?

Problem using JDBC (JNDI) DataSource and data-sources.xml w/ OC4J

I have a JClient application developed in JDev X. It works fine when using a JDBC URL for the connection (which then writes the connection into the BC4J.xcfg files, one for each application module). However, I would like the app to retrieve the data source from the server's data-sources.xml file. However, when, on the configurations tab of the application module I set the connection type to JDBC DataSource, and give it the JNDI name, it does not work, either with the embedded OC4J or the stand-alone OC4J. Any suggestions???
In the stand alone OC4J I verified that the data source exists (using java -jar admin.jar ormi://nemethzoltan3 admin welcome -application adatklinika -testDataSource -location jdbc/adatklinikaCoreDS) ... so the data source is defined in the data-sources.xml. Of course the error I get is JBO-30003.
If I just try to "test" the data source in Jdeveloper (using the context menu of the app module, and setting it to use the adatklinikaCoreDS) I get a JNDI error: unable to lookup data source and at level 3 a "javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial". I checked, the data source is defined under tools->embedded OC4J properties->data sources.
If I try to run the main form, simply nothing happens.
Please help!!!

Ok, figured out why running from jdeveloper wasn't working: the embedded OC4J server wasn't started (start it by running an html page from your project or something...and make sure you don't have a stand-alone oc4j running). AND more importantly it didn't have the library "embedded oc4j client" library included (project properties -> profiles -> development -> libraries)...which is needed for whatever reason.
Now to try and get it working with the stand-alone OC4J...

How to add a data-source.xml to the project to config DB connections and to be SCM'ed

I'd like to explicitly manage a data-sources.xml for my JSP + BC4J project.
Any helps on getting the released Jdev to add a data-source.xml that would then
be what the .ear deploys to OC4J?
Thanks, curt

I have a JSP + BC4J project:
So far my naive experiments to explicitely add data-sources.xml to a
project that is picked up by the deploy to .ear step and put in the
root of the .ear have failed.
Is this one of those gaps like the orion-application.xml file, that has no
solution at present?
Or is the back-door via adding an EJB component to my project, then deleting it??
Thanks, curt

Data-source.xml location

Hi.
I have a web application, so I included the file data-source.xml and orion-application.xml in the project.
If I run the application through JDeveloper every thing is ok.
But if I make a deploy in the server, I get the following error:
javax.naming.NameNotFoundException: jdbc/smCoreDS not found
I was checking the ear and war file and I realized that the data-sources and orion-appications.xml were in the war file instead of the ear file.
How can I make to JDeveloper puts the file in the path META-INF in the ear.file instead of in the path WEB-INF\classes\META-INF in the war file
regards

To the web.xml of the web application add
<resource-ref>
<res-ref-name>jdbc/smCoreDS</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>

Factory-class in data-sources.xml managed-data-source

Data-sources.xml

Hi All,
In the 'Connections-Navigator' I have made some database connections, when I deploy my application JDev creates a file data-sources.xml ant put it under META-INF directory of ear file. But I am not able to see this file anywhere in my source tree. Is there any way to see and edit this file? Actually I want to enter some pooling related options in this file.
Thanks,
Vinod

hi Vinod
In my "SomeApp" workspace it appears in the same directory as SomeApp.jws, named SomeApp-data-sources.xml
see also:
"JDev 10g : no control over data-sources.xml"

How to prevent data-sources.xml from being included in EAR

I cannot get rid of the data-sources.xml file in my EAR file in the meta-inf folder.
Deselecting the "Bundle Default data-sources.xml during deployment" in my preferences didn't have any effect. I also tried shutting down/restarting JDeveloper just in case it was cached.
I also tried adding an exclude filter for data-sources.xml in my deploy profile for both Web files and WEB-INF/classes.

The way I resolved this was to create the data-sources.xml, right click it, select Properties then uncheck Auto-update data sources.xml. That way it stays empty (hopefully).

ConnectionCacheName not read from data-sources.xml

I created a simple web application to test the use of the ConnectionCacheBean (from the jdbc 3.0 examples page). I read through the code and some other articles regarding data sources and noted that you "should" be able to set the connection cache name and caching enabled, as well as failover support, even in oc4j 9.0.4 and 10.1.2. I tried this (at least the first two), and it would NOT set the cache name.
The data-sources.xml entry was the same as in the one documented here:
http://www.oracle.com/technology/tech/java/newsletter/articles/oc4j_data_sources/oc4j_ds.htm
What gives?
Also, I tried to simulate the database going down - I killed all the sessions rather than doing a shutdown, but anyway... even with a connection cache property of validatelogin (i think that's the name) to true, and a refresh of invalid connections (they'd all be invalid if I killed them), it would only reactivate ONE SESSION. If I refreshed ALL Sessions, then it would do 9 of the 10 sessions (10 being my initial cache limit).
Any ideas?
I can post the code if that is an issue.

A response I got back from Frances Zhao regarding the two issues that I experienced was:
Issue#1: Cannot set the connectionCacheName via data-sources.xml
1. This is very likely because of an OC4J bug that affects the actual order of
    setting each <property> specified in data-sources.xml. The connection cache
    in OracleDataSource requires the cache-name property be set after the cache
    is enabled; but OC4J may not always follow this order, causing the name
    to be null. If you really need the cache name, you have to do it in the code
    for now.
Issue#2: Can't refresh the invalid connections
2. These are known issues in the Oracle JDBC driver in both 10.1.0.4 and
    10.2.0.1. The fix for the REFRESH_INVALID case will be in the next
    patch release for both 10.1.x and 10.2.x; the fix for the REFRESH_ALL
    case will come later.

HI,
Thanks for the response, I already went through these threads.
My exception seems to be related to this - Problem with connection sharing if J2EE transaction is running
and suggested solutions seems to be:
The problem is caused when there is an inappropriate attempt to open a second connection in an active JTA transaction. There is either an attempt to get a second connection from an un-shareable non-XA DataSource or an attempt to get it from another non-XA DataSource. You have to:
●     Use no more than one connection from this data source while the JTA transaction is active or
●     Declare the data source as shareable, depending on your application logic.
Question is, How can I make data source as shareable??
This application worked fine in JBoss, weblogic and now we are trying to port it to NetWeaver.
Is any of the above options are configurable in data-sources.xml?
Thanks for your guidance and response.

Missing data-sources.xml deploying war with jdeveloper 9i RC

When deploying a war file to an OC4J 1.0.2.2.1 server and error reports during the deployment that data-sources.xml is missing in the application-deployments/xxxx directory. Only the orion-application.xml file is present - which references a data-sources.xml file in the same directory. The problem is : it isn't there.
When I copy the xml files from the applications/xxxx directory to the application-deployments/xxxx directory and redeploy the war file everything works fine.
Is this a configuration issue or a bug ? Anyway, can somebody tell me how I can work around this problem ?
Thanks !

this is a bug and you have already found the workaround.

10.1.3 Migration Issue with data-sources.xml

Hi:
Running into lots of migration issues for an application built in 10.1.3 EA, migrating to 10.1.3. production, mostly in the BC project. Here's one: the database connections built in EA were not carried over to prod, so they needed to get re-built. No biggie. But now the data-sources.xml file in the model project has duplicate entries for my data sources. I have tried directly editting that file and removing the duplicates, but when I go to run my application (ADF Faces & ADF BC) JDeveloper hangs. When I abort JDev and re-start it, the duplicate entries are back in data-sources.xml (and yes, I did save the file after making the changes). It seems that the xml file is built dynamically from definitions stored elsewhere. Where is the source? What will I need to modify to get the changes to take?
Thanks.
Johnny Lee

There is new control over when/whether JDeveloper add/updates your data-sources.xml file for the embedded server. The settings are located here:
Tools | Embedded OC4J Server Preferences | Current Workspace | Data Sources
There are some settings there that control whether/when we update the data-sources.xml

[HELP] data-sources.xml on META-INF for deployment

Hello,
I'm having a problem in the configuration of POOL OF CONNECTIONS, I created the file and data-sources.xml orion-application.xml, and I am not able to add the same folder META-INF when I create the deploy the application (EAR). What can I do for the time that I generate the deploy the files have to go to the right folder.
Thank now ...
I am using:
JDeveloper 10.1.3.3

If application is to run on embedded OC4J, a EAR file is not required.
1. Create a datasource, either declaratively in the data-sources.xml file or in the Connections Navigator or in the Global/Project DataSources.
2. Specify the data source in the application.
3. Run the application in the embedded OC4J.
