Data-source.xml - BaseResourceException - two phase commit

Hi,
I am seeing the following exception.   Please let me know how to fix this.
thanks
Sunita
com.sap.engine.services.connector.exceptions.BaseResourceException: The resource "xxx" does not support two-phase commit and cannot be enlisted in the current transaction, because another non supporting two-phase commit resource is already enlisted for component "webContainer/applications/JavaEE/YY-TPRO/YYr-TPRO" in application "JavaEE/YY-TPRO". Only one of the enlisted resources is allowed to be non two-phase commit compliant.
I am using JDBC 1.x datasource, and the .xml looks like this:
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE data-sources SYSTEM 'data-sources.dtd'>
<data-sources>
<application-name>JavaEE/yy-TPRO</application-name>

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.

ADF Service Interface: two-phase commit issue for multiple data sources

In FusionApps, For a service interface we had to use two DataSource resources (in the ejb-jar.xml),
one is ApplicationServiceDBDS for SI and the other one is ApplicationDBDS(I don’t know the exact reason why this is needed, but when running the webservice, Framework was throwing an error asking for this) After adding these two, now(while running the webservice) we’re caught up with an error saying that unable to participate in two phase commit. I think this is because we added two dataSources, if we just use one dataSource everything is working fine.
Error message from app server:
"JDBC driver does not support XA, hence cannot be a participant in two-phase commit. To force this participation, set the GlobalTransactionsProtocol attribute to LoggingLastResource (recommended) or EmulateTwoPhaseCommit for the Data Source=ApplicationDB"
we have made the changes to ApplicationDB as said in the error message, but then the server is failing to start because of this.

Hi,
this is what the doc says - though not about two phase commit but transaction sharing:
"At runtime, the calling client and the ADF service may or may not participate in the same transaction, depending on the protocol used to invoke the service (either SOAP or RMI). Only the RMI protocol and a Java Transaction API (JTA) managed transaction support the option to call the service in the same transaction as the calling client."
When your application accesses a remote ADF Business Components service, each remote call is stateless, and the remote service will not participate in the same transaction as the business component that uses a service-enabled application module's service interface.
In the majority of the cases, calls to remote services will be informational in nature and will not make changes to remote objects. However, if you must use a remote service to make changes, then keep these points in mind:
An exception thrown by the remote service will cause the local transaction to fail.
If you successfully call a remote service that results in modifying data, and then subsequently your local transaction fails for any reason, then it is the responsibility of your error handling code to perform a compensating transaction against the remote service to "undo" the previous change made."

Two phase commit and bean managed transactions

To all the Transaction GURUS!
          Hi guys (-and gals).
          I've been doing J2EE for quite a while, but today was my first at
          XA-Transactions and Bean Managed Transactions.
          Why am I doing this?
          ====================
          Well I have to be able to controll the transactionalbehaviour of my
          bean
          during runtime, since some bean calls would cause a transactional
          overflow due to the stress they would cause to the system, whereas
          smaller bean calls need to run in one transaction.
          -> Therefore I need Bean Managed Transactions
          Since the bean does a call on two Database Connections it has to use a
          XA-Transaction.
          -> Therefore I need XA-Transactions.
          Abstract
          ========
          - I just can't get a User TransAction into the right Status it stays
          in 'STATUS_NO_TRANSACTION' all the time
          - Therefore the SQL Commands can be comitted 'java.sql.SQLException:
          Does not support SQL execution with no global transaction'
          - Therefore I can't do a rollback 'java.lang.IllegalStateException:
          Transaction does not exist'
          - Therefore I wrote this mail.
          I don't want to be a smart-"ass" writing such a detailed and indepth
          mail. I just would like to show that I tried, and would like to have
          some replies from you guys.
          Below are my configurations, code and logfiles.
          Thanx for taking your time and hope that the other people may learn
          something as well.

          I'm going nuts.
          I just don't get it.
          The transaction is the same. I don't change the Connection. I start
          the Transaction at the beginning before I do anything!
          Please guys help me out.
          Thx alot.

Hi Priscilla
          (did you ever see the movie ? :-))
          Well I moved away from the idea of using bean managed transaction. I'll
          be using Container Managed Transactions. To modify the
          transactionalbehaviour I'll write proxymethods which have certain
          different containermanaged transaction properties, but which all call
          the same private methods.
          But it works! Here is my experience:
          - I was doing a DDL statement: I was trying to create new Tables, which
          is a definite "no-go"
          - pay careful attention to:
          http://edocs.bea.com/wls/docs60/jta/trxejb.html#1051405
                    and

          and use these Settings for the Pool, don't ask me why, but it took me
          hours to find it out by myself:
               <JDBCConnectionPool CapacityIncrement="5"
          DriverName="weblogic.jdbc.oci.xa.XADataSource" InitialCapacity="1"
          LoginDelaySeconds="1" MaxCapacity="2" Name="oracleSecurityPool"
          Properties="user=xxx; password=xxx; server=xxx.xxx.xxx"
          RefreshMinutes="5" Targets="fbsserver" TestConnectionsOnRelease="true"
          TestTableName="Users" SupportsLocalTransaction="true"/>
          where as the server (shown as: xxx.xxx.xxx) is the TNS Name of the
          Oracle Driver.
          It works great.
          Another thing you guys might want to do is write a simple StatelessSB
          which does JDBC calls and two different database Connections.
          Then write a UnitTest which calls this bean a couple hundred times (with
          the same transaction). Have one test do clean writes, and another which
          causes some SQL-Exception (too long Data Columns, or likewise).
          Always count the entries and see if everything worked out. We're using
          this SetupConstruction to test new combinations of AS(sorry Priscilla) /
          Database / Db-Drivers to have a "standard test".
          I know my two cents were uncalled for, but it might save you some
          time.....
          thanx for your help
          Stefan

          Betreff: Re: Two phase commit and bean managed transactions
          Hi Stefan,
          Looks like you have not actually begun a transaction by calling
          UserTransaction.begin(),
          so your setupTables method is really executing with no transaction
          context.

Configuration of two-phase-commit in OC4J 10.1.2

Configuration of two-phase-commit in OC4J 10.1.2 in application with multiple modules
We have an application ear file consisting of ejb-modules (mdb and slsb) and two web-modules. We are using Oracle's advanced queueing for messaging and CMT (all ejb use the Required transaction attribute). We need different datasources (OrionCMTDataSource) including that for aq, so we need two-phase-commit. The web clients use ejbs and browse the messaging system. Our 'orion-application.xml' includes a commit-coordinator configuration, and the database is setup correctly. The configuration works fine for mdbs, when sending messages to the queues. When a client starts after messages have been sent and consumed by the mdbs, oc4j complains that no commit-coordinator is defined in 'server.xml'. If we start the client first, it can access the queues, but then the mdbs complain. It seems that the first one "gets" the commit-coordinator and the second one fails.
Some questions:
Why isn't the second client type using the commit-coordinator configuration of the "orion-application.xml"?
Is such scenario not supported by OC4J?
How can I setup the application correctly?
How do I configure commit-coordinator with different datasources to the same database? (Commit-Coordinator is also this database)

Take a look 'How to Use a Custom Serializer with Oracle Application Server Web Services' [1].
In your case, you should be looking at BeanMultiRefSerializer (org.apache.soap.encoding.soapenc), which will serialize your data using href and providing a way to deal with cycles.
All the best,

How to recover in a two phase commit ?

I am implementing a two phase commit with Oracle XA in Oracle 8.1.6. I am wondering how I can recover from failures occur between the PREPARE and the COMMIT stage. If I lose the database connection after the changes have been prepared, then I can't find a way to rollback or commit the changes.
Appreciate any helps.

The iPod OS takes care of where/how to store the files on the iPod and it has not done this. This is why you need to get the files off your iPod first.
My goal is to connect my iPod to my Mac, launch iTunes, and all of what's on my iPod displays in iTunes after single-clicking the iPod's icon in the Source pane of iTunes' window.
This is very, very simple. This is how iTunes works normally.
Since you now have the stuff from your iPod on your computer (using Ollie's iPod Extractor), load them into iTunes.
Sync them to the iPod. This will update the iPod database so all of the files are seen/identified correctly by the iPod.
Set the iPod prefs in iTunes to manually update.
Now you can delete the stuff on your computer and iTunes and view/edit/delete the stuff on the iPod using iTunes.
The outcome of using the utilities suggested in previous posts is that all of what's on my iPod gets copied to my Mac's hard drive (which is not what I'm trying to accomplish) and then that displays in iTunes' Library.
Only because the files on the iPod are not "useable" with the iPod or iTunes right now.
This is not something you will have to do everytime.
Once you get them on your computer, you can do the above steps and you will not have to use any utilities.
Just use iTunes.

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.

Two Phase Commit on Slow Network

Can I implement two phase commit transaction using Windows 2000 Professional's Dial-Up Connection ? Where would I find information on this ? I connected two Windows 2000 Prof. PCs using Dial-Up Connection on Telephone line. Now if I try to ping service on other PC using TNSPING it gives me connection timed out, how should I tackle this issue ?

Hi Ioakim
Performing an atomic transaction(ACID) that spans a source system, BizTalk and then a different destination system is not possible. This is due to the nature of distributed transactions - it may not be practical to hold locks on resources(needed for atomic
transactions) that are spread across different networks. Given that there is no guarantee that the resources may be released in a reasonable amount of time, transactions in BizTalk can only be scoped to and from the BizTalk MessageBoxDb. Or in other words,
you can read a record to BizTalk transactionally and on the send side, send a message from BizTalk transactionally.
However, you can simulate/fake atomic transaction characteristics(although tricky) using compensation logic within BizTalk orchestrations. So, lets say you read+delete a record from SystemA into BizTalk, and that record has to be updated in SystemB.
If for some reason the insert to SystemB fails, you would have to write custom logic in a compensation block that then performs the reverse operation in SystemA - i.e., it inserts back the record in SystemA in this case. So, using compensating actions, it
is possible to ensure that all the systems involved are transactionally consistent at the end of the day.
There's an article from C.Young that discusses this in some detail-

What is two phase commit in Forms?

Hi
Could any one tell me,
what is two phase commit in Forms?
Cyp

Hi,
two phase commit is a database feature that ensures data consistency.
"Oracle's two-phase commit mechanism guarantees that, a distributed transaction will either commit on all involved nodes or roll back on all involved nodes."

Different data-sources.xml files for each build

Any thoughts on how to do this:
I have two sets of data-sources. When I deploy the EAR to my stage box, I need to go to the "stage" data source of the other repositories. When I deploy the EAR to my production box, I need to use the production data sources for the other repositories
I am using jdev 10.1.3
There is a single data-sources.xml file - where, currently, I am manually editing the connection strings between deployments.
I am using ant to build the EAR file.
What is a more elegant way to do this?

Use ANT script to build the EAR file.
Have 2 different data-sources file one for production and one for stage.
Based on the environment you want to deploy tell ANT to copy those files into the EAR.
Just a suggestion.

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
my data-sources.xml
<data-sources>
     <data-source
        class="com.evermind.sql.DriverManagerDataSource"
        connection-driver="oracle.jdbc.driver.OracleDriver"
        ejb-location="jdbc/DEVDS"
        location="jdbc/DEVCoreDS"
        name="DEVDS"
        password="j2train"
        pooled-location="jdbc/DEVPooledDS"
        url="jdbc:oracle:thin:@10.2.1.30:1521:GDOC"
        username="jscribe"
        xa-location="jdbc/xa/DEVXADS"
        inactivity-timeout="300"
        max-connections="50"
        min-connections="40"
    />
</data-sources>

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?
Thanks, curt

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-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"

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

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).
