Issue implemeting Implicit Transactions using TransactionScope with Oracle

I’m implementing Transaction support in an application using Transactionscope (have done this for other providers with no issue’s ) , for Oracle 10g Database , with Oracle Client 11g installed on my system . The Code is as simple as below . But the instant the Oracle connection attempts to Open , I get different errors , for different Oracle Providers , for the same action (Opening the Oracle connection within a Transactionscope ) . Googling for the error returned a lot of people who have faced the isssues but no solution.
System config :
1)Oracle 10g databse
2)Oracle Client 11g
3)MSDTC enabled
4)OraMTS.dll registered
5)OS; Windows XP
Am I missing out any configuration settings .Please help
Any idea what could be the reason . has it got to do with some kind of settings/ configurations.
DbProviderFactory factory =DbProviderFactories.GetFactory("System.Data.OracleClient");
//DbProviderFactory factory = DbProviderFactories.GetFactory("Oracle.DataAccess.Client");
string constr =@"Data Source=(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = ind-mhp1w3s0015)(PORT = 1521))) (CONNECT_DATA = (SERVICE_NAME = XE)));User Id=refapp;Password=refapp;enlist=true";
using (TransactionScope scope =newTransactionScope(TransactionScopeOption.RequiresNew))
//using (DbConnection conn1 = factory.CreateConnection())
using(OracleConnection oraconn =newOracleConnection(constr))
oraconn.Open();
Error encountered :
1) Data provider internal error(-3000) [System.String] :-Provider :Oracle.DataAccess.Client
2) "Attempted to read or write protected memory. This is often an indication that other memory is corrupt." Provider:- System.Data.OracleClient
Thanks & Regards

do not have access to an 11g database ..else would have tried it . Can you please let me know what are the settings that you have done on ur sytem.

Using Tuxedo with Oracle Real Application Clusters (RAC)

Hi all ,
Our present Producation environment is Tuxedo8.0 with Oracle 9i as database .
We are planning to implement oracle RAC .
Can any one tell us , with the current tuxedo version which is 8.0 ,can we for RAC Or we need to upgrade Tuxedo to 9.1 for RAC Implementation?
If anyone has Implemented Tuxedo and Oracle with RAC successfully
Pls share your experience.
Thanks In Adavance
Nadeer .

Subbu,
As I mentioned earlier in this thread, support for Oracle RAC has been
implemented in Tuxedo 9.1 and in the Tuxedo 8.1 and Tuxedo 9.0 rolling patch
streams. There are no plans to backport this feature to Tuxedo 8.0. If you
plan to use RAC transactionally and if it is possible for multiple services
that could be located on different RAC instances to be accessed in a single
transaction (which will be true for most applications), then you should
upgrade to a version of Tuxedo with support for Oracle RAC. The
documentation at http://e-docs.bea.com/tuxedo/tux91/ads/adorac.htm#248431
gives an overview of RAC support in Tuxedo.

Hello Nadeer, Hello Ed,
Has the implementation of Tuxedo8.0 with Oracle RAC was completed
successfully ?.
If it is done , I have few doubts. Could you please help me ?.
1) I hope your Tuxedo middleware connects to the oracle Database using
Oracle XA resource manager and the TMS server built using buildtms with
oracle as RM .As per the mail from Ed, migration of Tuxedo9.1 should be done
before moving to Oracle RAC.
Also from BEA documentation, Oracle RAC support was given as new feature in
Tuxedo9.1.
Our Application uses Oracle RM to connect to Oracle DB[ Oracle 10g] from
Tuxedo8.0. So do we need to upgrade to Tuxedo9.1. for using Oracle RAC ?.
Thanks for your help

Using XA with Oracle ERP application

Hi,
We have two Tuxedo Domains that we need to establish global transaction:
First Domain - Tuxedo 6.4 with Oracle 8.0.6 database.
Second Domain - Tuxedo 6.4 with Oracle ERP application (Oracel version 8.0.5)
A Client that calls a Tuxedo server in the first domain this service doing some work
on the database and then calls another service in the second domain (using Domain
connection).
The service in the second Domain activate a Oracle API (package) from the ERP application.
The Rollback works but we problem with the commit. We recieve the following Oracle
Error - ORA-06574: Function "VIEW_ALL" references package state can not execute remotly.

Using OCCI with Oracle XA Library

Is it possible to use OCCI with Oracle XA Library?
the XA function xaoSvcCtx() can returns the OCI service handle
for a given XA connection. but how to convert it to the OCCI
Connection class?
any comments would appreciate
Ray

Hi Ravi,
We are now building CORBA application with C++. some programs
manage transaction through Transaction service(a TM of X/OPEN
DTP architecture), these programs must use XA Library.
OCCI is a wonderful tool for C++ programer,with OCCI building
a persistent layer over ORACLE is very simple.
But if OCCI not work with XA we have no choice but PRO*C or
OCI ,which's actually C style tool and hard to use especially
in object mode.
So we hope OCCI can provide this feature in next release. and
I beleive This feature is necessary,It's very common using a
transaction monitor such as ORACLE Application Server .
regards,
Ray

Using Mts With Oracle Database

Hi,
Oracle JVM in 11gR2 (the latest release) supports Java 1.5 only. So no, you won't be able to load classes compiled with target class level 1.6 into DB. But you surely may explicitly set target class level of 1.5 in javac and then load compiled classes. Or you may not use 1.6 features in your code and then CREATE JAVA SOURCE from it.

Problem while using XML with Oracle

I have a problem using XML with oracle applications
The process I am following
1. Making a XML string.
2. Parsing it to get a document
3. Free the parser using xmlparser.freeparser
4. Traversing through nodes .
5. Freeing the document.
The whole Process is executed in batch mode.
The problem occurs after executing the procedure for 5000 records and I get the error
ORA-04031: unable to allocate 4176 bytes of shared memory ("shared pool","unknown object","sga
heap","library cache")
Can you please help me out to overcome this problem
It's urgent
I have
Oracle version 8.1.7.0.0
XML version 1.2
OS Windows NT
To resolve the problem I have increase shared memory size and java initialization parameters ,which seems OK
Looking forward for your answer.

Hello, Reena
Your process flow seems to be correct in term of getting/freeing memory.
Following error
The problem occurs after executing the procedure for 5000 records and I get the error
ORA-04031: unable to allocate 4176 bytes of shared memory ("shared pool","unknown object","sga
heap","library cache")may be caused by memory leaks in xdk or memory fragmentation(due to get/free memory cycle)
To find out if this is an memory leak issue you could try to monitor V$SGASTAT from one session while running your batch process in another session.
To prevent (or lower its impact) fragmentation issues try to PIN objects, and adjust java_pool_size and shared_pool_reserved_size.
Anyway, counsult your Oracle DBA.
Oracle version 8.1.7.0.0I think, you should apply database patch first of all. The latest one (8.1.7.4.x) could be accured from Metalink.

Thanks you in advance for your answers.Looking at the 8.1.7 doc set (the oldest available on tahiti) I get no hits when searching for 'dict_from_online_catalog'. Searching the 9.2 doc set turns up a reference. Looks like you are trying to use an option that isn't available in your version of Oracle.

Using psp with oracle text.

Using jfreechart with oracle forms 11g

Hi everybody,
I'm using jfreechart with oracle forms 11g to continue having graphs in my application since i'm migrating from forms 6i. I've already got it working and it's great. Just have one problem left. I don't know how to change the axis labels. In Bar charts, it comes with "Values" in y axis and "Category" in x axis by default. I wanted to change that or make it dissapear. Anyone knows how to?

I've never used the jFreeChart, but according to their website you can use the "setLabel" method to set the label for an axis. Check out Axis (JFreeChart Class Library) for more information.

Can we use WebUtil with Oracle Forms 6i

Can any one tell me if we can use WebUtil with Oracle Forms 6i..I have 11.5.9 instance of oracle apps and i want to use some features of WebUtil to customize one of seeded Oracle Form.
Any pointers in this regard are quiet welcome.
Thanks,

Strictly speaking no...however you could "backport" the webutil code and in theory you could get some of the functionality to work - this is not supported in the context of oracleForms although Oracle Applications may have their own specific solution/certification of this.

Issues with using utl_http with Oracle Wallet

Hello Everyone,
We are experimenting with Oracle wallet and utl_http and are attempting to do an https transfer and we are facing some problems. I will appreciate your help greatly if you can advise on what could be wrong. We are on db version 10.2.0.1 and Unix HP-UX. The intention ping an https url and get a simple 200 response. Future development would include get/post XML documents from that url and other interesting stuff. I understand that utl_http with Oracle wallet can be used for this purpose.
The wallet has been created and the ewallet.p12 exists. We downloaded the SSL certificate from the url's website and uploaded into the wallet.
Everything works if I put in a url with plain http. However, it does not work with an HTTP*S* url.
With HTTPS when I run the below code I get the following error. Again, greatly appreciate your time and help because this is the first time we are using Oracle wallet manager and do not know where to go from here.

Using php with oracle http server

Hello folks
This question might have been answered on this forum, but i haven't found it yet.
Is it possible to integrate php into the apache server that is supplied with the oracle (9.2) database, the so called Oracle HTTP Server?
What technical issues are to consider and how do you do it on linux in that case? (SLES8)
Is there any support issues to consider if somebody modifies this oracle supplied http server?
Looking very much forward to some help...
Regards,
Christian

Transaction timed out with oracle 9i

Hi,
I am working with weblogic6.1.
Sometimes (very seldom) I have a problem which I don't undserstand.
The transaction stops and and after some time I get TimedOutException.
This time it happend in the findByPrimaryKey of a CMP Entity bean.
I have this problem only with Oracle 9i. with oracle8i everything works
fine.
I'm using oracle thin driver (I put oracle12.zip at the begin of weblogic
classpath)
Is this problem of oracle?
Does WLS 6.1 support Oracle9i?
Thanks for any hints

I set the JTA-->Timeout Seconds to 30 in the thr the Weblogic console. The
configuration of the server is WebLogic 7.0 with SP2 and Oracle 8.1.7.
Anyone know what happen and how to resolve the problem? The error is due to
the entity bean, Weblogic or Oracle?
Thanks a lot.
IreneOr configuration. You can set your timeout to a different value. It is likely
to be an oracle problem. We don't do anything unnecessary to delay your application
code. You may be able to check the jdbc log or jta log to see when the tx starts and
how long it takes to progress. If you note a delay, you could take a server
thread dump to see what weblogic is doing. Typically it will be waiting for
Oracle to respond from a jdbc call.

Using JDeveloper with Oracle 10g Express Edition

Hi,
can JDeveloper 11g 11.1.1.4.0 Studio Edition be used to develop applications connection with Oracle 10g Express Edition?
If not, is there a version downloadable that can?
TIA

Yes, it can.

Using Java with Oracle Spatial

I am using the JDBC (Java classes dowloaded from
technet.oracle.com - (sdoapi.zip)) together with Oracle Spatial
8.1.6. I am writing a collection of Linestrings into Oracle
Spatial using the supplied java classes(sdoapi.zip). I use the
function createGeometryCollection(myCollection)to write the
Linestring collection to Oracle Spatial and they are written to
the database without error. However, when I try to read the
object back I get the following error:
Exception in thread "main"
oracle.sdoapi.geom.InvalidGeometryException
at oracle.sdoapi.adapter.AdapterSDO.importGeometry
(AdapterSDO.java:101)
at
MapInfoToOracleSpatial.MapInfoToOracleSpatial.main
(MapInfoToOracleSpatial.java:211)
I do not have a listing of this code so can you please tell me
what the error is (line of code) at line 211. Also, when I use
the Oracle Spatial Index Advisor to view the spatial data, it
only displays a quarter of the data. When I use MapInfo to view
it's equivalent TAB (Table) file it views correctly all the
data.
I can't understand why this is happening because the writing to
oracle and creation of each individual linestring does not
throw an error. It is only when I try to read back larger
objects from the database (2500 points) that it gives an error.
Is there a limitation on the size one can create linestrings?
Thanks
