WLS 7.0 JTA Oracle example problem

Hi,
I am trying to get the Weblogic 7.0 JTA, Oracle example working.
This example uses two deployed EJB's and different data sources to
transfer money from one to the other.
The example specifies that one of the database pools should be using
an OCI driver. Unfortunatley I don't have these drivers, and really
only want to use the Oracle JDBC thin drivers. The drive I am using is
oracle.jdbc.xa.client.OracleXADataSource
I have set up two database connection pools, both using XA Java thin
drivers.
Every time I run the example is throws an XA error: XAER_PROTO. I
think this is something to do with the XA transaction not being setup.
Have you been able to get the example to work???
Is there some technique in setting up Oracle XA database pools, and
datasources that I am missing?
I am using Oracle 8.1.7.
Thanks for your help.
Regards.
Andy
Here is the stack trace when I try and run the example.

Thanks it worked. Somehow I missed in documentation this x.509 setting.
I've also had a problem with setting "Client Certificate Requested But Not Enforced"
in WLS 7.0.0 but it seems to be working fine in SP1.
Thanks again

Hi!
I'm trying to set up my web application to use client-cert
authentication. I've set in web.xml login config to
<auth-method>CLIENT-CERT</auth-method>. When I'm accessing my
application I'm always getting 401 Unauthorized. If I set
login to BASIC, browser pops up login dialog and everything works
fine.
I've done following:
- created and installed in WLS trusted CA certificate
- created and installed client certificate signed by that CA in
IE 5.5
- configured WLS to use ssl and set "Client Certificate Enforced"
- managed to connect to document root or console application
using https://localhost:7002/console and verified that accually client
certificate
is used (not able to connect without one)
Now I'm really stuck and have no ideas.
Please help. Thanks in advance.

ConnectionPool problems with WLS 7.0 and Oracle 9.2

Hi,
We are using WLS 7.0 SP4, and Oracle 9 and the Oracle thin driver type 4. In our
application on the productive system (and only there) we constantly encounter
a whole set of SQLExceptions which have all in common that the Connection from
the pool is not valid any more when the application tries to use it.
Typical, recurring error messages are:
- Exhausted ResultSet
- Connection has already been closed
- Closed Statement
- Transaction is no longer active - status committing
- NullPointerException at
weblogic.jdbc.pool.Connection.prepareStatement()
There are no special Statements which create these errors. They are spread at
random across practically every query the application creates, and the same queries
sometimes succeed and sometimes fail.
I double and triple checked that all Connections, Statements and ResultSets are
closed immediately after use. As an example, I attached a code snippet and a resulting
StackTrace which.
The problem also seems to occur only with an (unknown) minimum of concurrent usern,
since in the approval tests on an almost identical test system these errors never
occurred.
I also followed the advice from Oracle and installed the latest Oracle JDBC driver
(Oracle 10g) - to no avail.
What else can I do?
Another question: Is it correct that my Oracle JDBC driver is in the application
classpath (via a reference in the Manifest file of the application jar), not in
the system classpath? There has never been a problem with that, but in a Newsgroup
answer from Nov 10, 2003 (subject: "ResultSet closes prematurely"), Joe Weinstein
suggested to "get it listed at the
front of the -classpath argument that the startWebLogic script creates for the
java line that starts the server".
I hesitate to do so, since the driver is in a standard WebApp- directory, WEB-INF/lib.
Is it possible and safe to add a jar located there to the system classpath? If
it is possible, why is it necessary?
Best regards,

Hi Joe,
Your hint that there is a threading problem was right:
On further investigation of the code I found out that the class that passes the
Connection to the DAO not only stores it as a member at some point (which is not
a good idea anyway) but is also a singleton - then, of course, it's no surprise
that the Connection gets invalid in a incalculable way when concurrent threads
share it.
The singleton instantiation was not so obvious because the way of instantiation
is controlled by a configuration parameter that can be overridden at different
levels.
I changed it and the productive logfiles indicate that the SQLExceptions related
to that class have disappeared.I am happy to have helped.
So, thanks a lot for the advice.
But I am still wondering why this code has worked for so long a time with WLS
5.1 and Oracle 8 (the system has been productive for over 2 years). Even in the
approval tests with WLS 7.0 and Oracle 9, we did not run into problems, although
it was multi-user environment.Mo idea.
I still believe that there is a difference between WLS 5.1 and 7.0 in the way
it treats pooled Oracle JDBC Connections. I wished both Oracle and Bea could be
a little more explicit about those changes and possible version incompatabilities
beyond the general advice "use the latest thin driver".Though I can think of no change to our pooling which would have had any material
effect in this case, I will certainly do what I can to see that our documentation
is explicit about changes.

Typical, recurring error messages are:
- Exhausted ResultSetThat is typically if the statement that created it is either re-executed
or closed.
- Connection has already been closedAs described. If you give a stacktrace, we could make a debug patch which
would show
where it was originally closed.
- Closed Statementsame as above.
- Transaction is no longer active - status committingThat implies your code is obtaining a connection from a transactional
datasource,
and then later trying to use it after the transaction which it was associated
with,
is finished.
- NullPointerException at

We also ship
an oracle thin driver, which becomes obsolete soon...
I am concerned that your code creates pool connections to be used later.
The problems
can arise if more than one thread ever gets the same connection, or if
the connection
is used in the same thread, spanning transactions. It does also seem
that there may
be a threading issue, because if two threads each call the code to create
a connection,
and two connections are made, but one over-writes the other, the two
threads can
end up using the same connection, and closing it. The over-written one
never gets closed,
resulting in that leak message you got...
Joe
The Connection parameter is opened by a business component class, ComaServiceProviderClassicImpl.It is propagated through
several classes in the business layer, but not used, until the DAOtakes it to make the query.
So, the Connection is closed where it was opened, not in the DAO class.
public class ConcernDAOImpl extends BaseDAO {
     public Collection getConcernsForIncidents(Connection conn, Collectionincidents)
throws DataAccessException, ConstraintException, ComaParseException{>
sqlMessage.append(")");
String sqlStmt = sqlMessage.toString();
PreparedStatement pstmt = null;
ResultSet rs = null;
try {
pstmt = conn.prepareStatement(sqlStmt);
rs = pstmt.executeQuery();
while (rs != null && rs.next()) {
final Concern concern =
new Concern(DAOUtil.getComaOID(rs, ComaDBNames.KDANR));
concern.setIncidentOID(DAOUtil.getComaOID(rs, ComaDBNames.KDAVGENR));
return concerns;
} catch (SQLException sqle) {
// Wrapps real SQL exception
String[] message = new String[]{sqle.getMessage(), sqlStmt};
throw new DataAccessException(ExpCode.S_ORACLE_SQL, message,
sqle);
} finally {
closeAll(rs, pstmt);
_logger.exitDebug(method);
Here, the Connection is acquired and finally closed
public class ComaServiceProviderClassicImpl {
     public void updateComplaint(
final Request updateRequest,
final ResponseSingleElement response,
final Principal principal)
throws SystemException {
try {
logger.info("updateComplaint", "store incident");
// store the incident in the database
incidentManager.storeIncident(getConnection(), updateIncident);
// reload the incident from Cache and / or the databaseto get the ContactReferences.
Incident returnIncident = incidentManager.loadIncident(//IncidentManager passes the Connection to the DAO
getConnection(), updateIncident.getOID());
} catch (RemoteException rex) {
// remote exceptions
rollbackIfNecessary();
CoreUtils.unwrapRemoteException(rex, logger);
} catch (SystemException e) {
// all other exceptions --> rollback if necessary and rethrow
rollbackIfNecessary();
throw e;
} finally {
removeConnection();
logger.exitDebug("updateComplaint");
This is the resulting StackTrace:

"Invalid Content Type" using oracle.example.hr empsecformat in EA2 listener

We've done a new vanilla install of Apex 4.1.1.00.23 and applied the patch that comes with the EA2 listener
We then created a workspace and logged in, looking at the Restful services we can see the oracle.example.hr in there.
Using the empsecformat/JONES
we just get an error of :
400 - Bad Request
Invalid Content Type
We get this if we use the test button on the page also.
Has anyone got this working out of the box?
The listener stdout isn't showing any errors what so ever

Does not only happen when using JAX-WS.
the following servlet code is enough to reproduce the problem :
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.setContentType("text/xml;charset=\"utf-8\"");
It only occurs on 10.1.3.4.0 (works fine on 10.1.3.3.0 and 11.1.1.1.0 TP4)

Upgrading from WLS 8.1 to Oracle WLS 10.3

Hi,
I'm planning to upgrade a client's system consisting of multiple applications running on WLS 8.1 to Oracle WLS 10.3.
Is this an officially supported upgrade path? What would be the best way to do the upgrade?
Are there any tools for automatically importing or converting the old configuration or domains?
Or is it better to create new installations from scratch and manually configure them?
Is there any documentation for this upgrade path?
In practice we would need to run both application servers in parallel for a while.
Can I expect the different server versions to interoperate with each other?
The applications mostly communicate using EJB (v2.0) calls but JMS and Web Services are used as well.
I've tested the EJB calls and they seem to work but what about JMS?

Thanks.
Can WLS JMS v8.1 be used as a messaging provider for WLS v10.3 and 8.1 instances
(using it directly or through the Messaging Bridge)?
Is this described in the documentation somewhere?
I also found the following documents that address version compatibility:
http://download.oracle.com/docs/cd/E13222_01/wls/docs103/compatibility/compatibility.html

Everyones Oracle Linux Problem solved!!!

Everyones Oracle Linux Problem solved!!!
Here's something Linux people should relate to: Use what works!
what works?
NT works! NT works great with 8i AND OAS.
No hassles at all!
Up and running within one day!!!!
Guaranteed!
U don't see a NT forum here with people having ridiculous install problems like Linux people?
Perhaps Oracle should moderate this newsgroup and even give an authorative answer or two?

I have switched our development and soon production databases to Linux because it runs like a charm. Fast and efficient, no problems. The installer has been a problem no doubt because Oracle put less of an emphasis on debugging their Linux installer than their idiot-proof NT installer.
By the way, I was able to circumvent installer problems by just linking svrmgrl to svrmgrlO; this avoided the dreaded segmentation fault and kicked everything open just fine.
BTW, about NT; what makes an OS is not how well everything works when everything is going well, but how bad it gets when something goes bad. For instance, the segmentation faults on Linux weren't a problem because I just picked up and continued; on NT you'd have to restart the whole system...not a pleasant feature.

duplicate thread, see this one -> Re: Oracle Designer Problem Please help me

How do I compile one of C/C++ Oracle Examples ? (Windows)

Is it simple? Can I just create in Visual Studio a Console API and plant the required headers chain to click compile ?
Or it needs a more specialised procedure ?

(Was that heronic?) I tried indeed :D
You have to include in your C/C++ Project the OCI headers and libraries from Server Instalation folder
In my scenario
Oracle 11.2g 32bit
Windows XP 32bit
Visual C++ 2005 Express Edition (v8)
Include Oracle Libraries
Project properties>Linker>General>Additional Library Directories : D:\oracle\product\11.2.0\dbhome_1\OCI\lib\MSVC
Project properties>Linker>Input >Additional Dependencies : oci.lib
If you have 64bit You might need to change the project target to 64bit if its 32 bit and vice versa
http://msdn.microsoft.com/en-us/library/9yb4317s%28v=vs.80%29.aspx
Additional Info
Oracle Example code is the one for Client Result Caching
I dont have the Companion Examples so I downloaded from here along with th header
http://read.pudn.com/downloads99/sourcecode/windows/database/402662/oci-demo/cdemostc.c__.htm
http://read.pudn.com/downloads99/sourcecode/windows/database/402662/oci-demo/cdemostc.h__.htm
For the Client Caching case they might be old and need edit before you activate it
I don't if I have everything I need and will be able to execute Statements and have full functionality yet.
But the basic Thread reason is satisfied. Will leave it open today if someone wants to add.

Is anybody has the example problem for AD/DA converter controled by PIC16F84?

In my circuit( Multisim 9), I use PIC16F84 as the
MCU to control the DAC and ADC. I want to ask if anyone has the example
problem for the controlling?
Further more, the I/O port of
PIC16F84 seems can not be connected with the digital output of DAC, so
I asked myself, is it right that for PIC16F84, the I/O port can only
connected with the serial port of DAC and ADC? Or it needs a converter
to adapt to the input port of DAC?
Looking for any help! Thanks!

You can test the new Design Circuit Suite (includes Multisim10 with MCU10 and Ultiboard 10 with Ultiroute10). When you open Samples you find the folder MCU with PIC folder. In these you can find some examples to PIC16F84. With that as pattern you should solve the problem.
I attached you here the MCU examples in the *.zip
For downloading the 30 days free test version you can use the link:
http://www.ni.com/academic/multisim/ and click to evaluation software
or these link:

Oracle BPM - Expense Management Example problem

Hi,
I have just started to explore Oracle BPM Version 10.3.2 and I am trying to execute the Expense Management Project as given in the starters documentation.
http://download.oracle.com/docs/cd/E13154_01/bpm/docs65/tutorial/index.html
After deploying the process and going into the workspace using
http://localhost:8585/workspace
I am not getting anything listed in the Applications tab. It is showing the following error:-
Could not retrievePrincipal applications for process '/ExpenseReporting'.
I searched in this same forum and came across this post:-
Re: Why there is no application in workspace?
which says that it may be due to version conflicts or some error coming up in the problems tab.
I checked my problems tab but it is not showing anything.
Eliminating this I thought it may be due to version conflicts (as i am following the post) so I uninstalled all my JDK's and just installed jdk 1.6 update 21 but still I got the same problem - i think this solved the issue for some users (Satya Anareddy)
Then in one comment in the same post given by Dan (Daniel Atwood ) i tried using the default 1.5 JM.
But still I am getting the same error.
I am completely confused as to what the problem could be.
Please could anyone give me some directions.
Thanks,
Rohit

Please follow this step may this solve your problem.
please modify any thing in process "ExpenseReporting" for example any transition or any activity to place some where else or any other modification and then save that process. Then clean the project and build and deploy it.
if this also not solve the problem then export that project to and import it again in your workspace (Create new workspace or change the project name in same workspace ) and then again clean, build and deploy the application then test in work space.
Thanks,

Can somebody help me find out why this problem is occuring..?

I am having problems deploying our application to a weblogic cluster. Environment is
windows 2000/XP and weblogic 7.0 SP2.
Here's a simplified version of the cluster.
I have 2 managed servers that are part of the cluster.I have defined the managed server
configuration in the admin server's config.xml as below.

Can somebody help me find out why this problem is occuring..?

"in-doubt distributed transaction" (WLS 8.1 SP2/Oracle 9.2.0.4)

          I've developed an MDB that reads a message from a queue, performs database updates
          against up to 2 databases, and sends an outgoing JMS message when all is complete.
          The MDB uses container-managed transactions to ensure that all DB updates and
          JMS messages are committed or rolled back together. I have had a lot of problems
          related to transactions failing, becoming "in-doubt" in the database and locking
          database resources indefinitely.
          My environment is configured as follows:
          WebLogic 8.1.2 Server
          Oracle 9.2.0.4 database with RAC
          XA Connection Pool with WebLogic Type 2 Oracle Driver OR Oracle 9.2.0.4
          OCI Driver
          I have read the BEA/HP white paper regarding Weblogic 8.1 with Oracle 9i RAC (http://dev2dev.bea.com/products/wlserver81/whitepapers/wls_bea_hp.jsp)
          and have tried all of the solutions suggested in that paper. The only solution
          that worked consistently without causing the in-doubt transactions was to change
          my connection pools to point directly to a single node of the RAC cluster, not
          to the shared instance. However, even with this configuration, I have seen these
          errors occur when certain database failures occur.
          A side-effect of this problem is that the associated WebLogic connection pools
          begin to "forget" connections. The pool thinks that all of the connections are
          in use (even though I am always calling Statement.close() and Connection.close()),
          and the connection pool cannot be reset manually. The only way to clear the connection
          pool is to bounce WebLogic.
          The only posts I have found related to this error were regarding Oracle 8.1.7
          and WebLogic 6.1. Any help would be greatly appreciated.

Hi. There is a serious bug in the Oracle DBMS (all versions) where in-doubt
          transactions have their data locked in the DBMS by page rather than by row,
          so it will indefinitely prevent access to all data on the page, including
          logically uninvolved data. Oracle understands the problem but currently
          says they will never fix it (it would take too much work). They offer the
          alternative that you configure your table data to ensure that no more than
          one datarow resides on a page.

Oracle insert problem(records not in the order they are inserted)

hi, all:
I tried to insert a word list into a oracle table, everything is fine except that the words are not in the order they are inserted. For example, the words are inserted in the following sequence:
accreted
accreting
accretion
accretionary
accretive
bladebone
bladed
bladeless
bladelike
When I retrived the resultset from the table and iterate through each of the record, the words are not in the order inserted, i.e., it may look like this,
accreted
accreting
bladebone
bladed
accretion
accretionary
accretive
bladeless
bladelike
This strange phenomenon won't happen when the word list is small, like 500 words or so, but when the number of words reaches around 10,000, it takes place. My coworker also experienced this problem when trying to insert large volume of data into oracle table.
The code I used to insert into the DB table:
BufferedReader reader=new BufferedReader(new FileReader("C:\\Dictionary.txt"));
while( (line=reader.readLine())!=null )
     sql="INSERT INTO DICT " +
     "VALUES ('" + line +"')";
     statement.executeUpdate(sql);
Any advice will be highly appreciated,
thanks

Well, the best thing to do is follows scsi-boy's advice and add the additional column and either put a sequence number in it from the Java side as you insert, or use an Oracle sequence object to put a sequence number in it from the Oracle side (which is sort of like an auto-generated value, but different).
Note that an Oracle sequence generates numbers in sequence, but possibly with gaps (usually if the database is rebooted), unless you do some things that slow sequences down substantially. Sequences can also be something of a bottleneck on RAC clusters. See:
http://www.dizwell.com/oracle/articles/autonumbering.html
However, if your coworker is commiting after each and every insert (which is bad form and slows the database down, -10 points), and if your coworker is also never ever ever updating the columns after they've been inserted, and if your coworker is using Oracle 10g and not some older version such as 9i, then your coworker could use the ORA_ROWSCN pseudo-column to order by. Those are very very severe constraints and you shouldn't begin to consider doing it that way without a very good reason, and right now you and your coworker wouldn't know a good reason if it snuck up and bit you on the butt, you've got a lot of learning the basics first.

Data source from Oracle 10g problem

Dear Sir,
We met a problem when we moved on Oracle 10g from Oracle 9i in the loading process. The scenario is that SQL Server as Data Warehouse, SSIS as ETL tool. But the length of string column as data source table in SSIS grows up 4 times when using Oracle 10g. For example, ABC table x varchar2(8) --> x varchar(32) -->x varchar(8) --> x varchar(8) {Oracle 10g SSIS(source) }
This doesn’t influence the loaded result (I did not find any problem until now), but that influence loading performance and we worry about potential problems.
Do you have any idea or have you met the same problem before? Is I need setup some parameters like "code page"
Thanks,
Jacob

You could try General Database Discussions the main db foum.
What are you using to migrate your database? Why is it being mapped from varchar2(8) to varchar2(32). It sounds like someone/something is intervening here.
