Transactions in oracle

Please explain me how to create transaction in Oracle.
Ex: If i have operations like
read, readmobile, write, writemobile, upadate.
then how can i create a transaction with these operations.
writemobile means a write operation issued by mobile device.
write means write operation issued by fixed host device.

I'm not sure I understand the question... As soon as you issue a SQL statement, you're starting a transaction. You complete a transaction by issuing a commit or a rollback. Assuming you don't commit or rollback in these "operations" (do you mean procedures?), you can simply call multiple procedures and then issue the commit or rollback.

Problem in Distributed transaction with Oracle 8.1.7 and Weblogic 7.0

          Hi,
          I am using two unmanaged weblogic 7.0 servers and oracle 8.1.7 enterprise edition.
          I am using oracle.jdbc.xa.client.OracleXADataSource for creating connection pool
          in weblogic. The pool gets created fine but when connection it is getting used
          it throws up following error.

ID is a NUMBER and id.toString() is not a number, for
example it ca be a null reference.
well we tryed also this version :
ps.setLong(1, id.longValue());
moreover the exception wasn't thrown for the value of id :56 but was thrown for the value of id : 88. Hence I think it is a case of something other than my code.

How to commit a transaction in Oracle Workflow

Hi All,
Oracle says there should not be any commit in Oracle WF .It is the responsbility of the calling program to Call Commit.
I have the following Requirement:-
I want to insert a record in one of the custom table, when a record is saved in one of the Oracle Apps Form( for e.g. insert a record in the custome table when user creates PO.)
What I have done is :-
1) Added a subscription to one of the seeded events that is raised when user saves a record in the Oracle apps.
2) Designed a Custom Function, that is called when the above subscription is triggered off.
3)The above custom function inserts a record in the custom table.
Q ) where to write a Commit ( as this custom function is called from the WF and WF says, dont put commit in the WF,it should be called by the callling program)
Can also you explain me , when user presses the Save button on the Oracle standard form--> that calls the Oracle API to create a record in the DB and commit , ---> then the event is raised and trigger offs all the subscriptions where does it commit then?
Thanks

Hi,
The commit should be done by the form, or whatever raises the business event.
The API fires the event in the same transaction (unless the subscription is deferred), and then the commit is issued. This commits the transaction, and all actions of the event subscription.
If the subscription is deferred, then the concurrent request which processes the subscription will issue the commit on completion.

How to configure global transaction wthin Oracle AS JMS and Oracle JMS

How to configure global transaction if I take a message from Oracle JMS(AQ) and send it to the Oracle JMS?

Which version of OC4J are you working on?
In OC4J 10.1.3.x, presume your OC4J JMS listens messages via MDB which uses a resource adapter as a message listener. The resouce adaper could be the generic JMS adapter deployed in OC4J as the default.
Resource adapter configuration to support MDBs is included in the standard ra.xml file, which lists the message listener types that the resource adapter supports.
The MDB developer or deployer configures the MDB in the ejb-jar.xml file, through a <message-driven> element.
In addition to above, configuration in the ejb-jar.xml file specifies whether an MDB uses transactions.
1) The <transaction-type> subelement of <message-driven> in ejb-jar.xml has a value of Container, and the <trans-attribute> subelement of <container-transaction> (under the <assembly-descriptor> element) has a value of Required. In this circumstance, if there is an imported transaction, then message delivery and related work are performed within that transaction. If there is no imported transaction, OC4J creates a transaction, and message delivery and related work are performed within that transaction.
2) The <transaction-type> subelement of <message-driven> in ejb-jar.xml has a value of Bean. In this circumstance, the MDB manages the transaction. If a transaction is imported, OC4J will suspend it before the message delivery method call to the MDB, in order to avoid conflict.
Message delivery is not transacted if the <transaction-type> subelement of <message-driven> in ejb-jar.xml has a value of Container, but the <trans-attribute> element has a value of NotSupported. If there is an imported transaction in this circumstance, OC4J will suspend the transaction before the message delivery method call to the MDB.
Details could be found from OC4J Resource Adapter Guide.

Importing Sales Transactions into Oracle Financials

I have a customer who is planning to use Oracle Financials as their finance solution, but we need to auto-feed the sale transactions from the sales system. These transactions corresponds (loosely speaking) to sales (or purchase) orders and delivery order. We have the ability to reformat the data (if necessary) to any format or through most interfaces (ODBC, XML, etc).
I just do not know enough about Oracle Financial to determine the appropriate format and connectivity.
I read on the Oracle Financial product page that it is possible to integrate that solution with third party solution - but there is hardly any other information available. So,
1. Has anyone done similar integration before ?
2. If so, can you kindly offer some advice - where (or whom) should I go next for more information ?
Thanks and best regards

Hello:
Project's activity management gateway (AMG) is the means to
import transactions into projects. This includes creating
tasks, budgets etc. For importing/recording commitments there
is a table that needs to be created and a view that needs to be
modified to show external commitments within projects (I believe
the view is named something like
PA_External_system_commitments_view)

Weblogic leaves in-doubt transaction on Oracle when it fails

Hi,
I'm looking at resilience with our Weblogic (6.1sp2) and Oracle
(8.1.7) environment, and have been doing a few tests. We're using the
Oracle OCI (thick) driver, in "XA" mode (i.e. using the "Driver"
oracle.jdbc.xa.client.OracleXADataSource). We need to do this because
our application uses JMS/Message driven beans to intiate a lot of the
work, and any database activity that fails needs to be rolled back
together with the message and any other work. We don't "enable
two-phase commit" as shown on the TxDatasource config, so get real XA
behaviour, with JMS and the JDBC connection as the XA resources.
The problem is when/if Weblogic dies. As WLS is the transation
manager, if a transaction is in-flight at the time WLS fails the XA
resources need to take action. If the TM fails after the transaction
starts but before the prepare() calls, it seems as though things
generally work out; Oracle rolls back its transactions, and when WLS
is restarted, the JMS messages are recovered and re-delivered (after
the initial delay period of five minutes). The problem seems to be
when WLS dies between the prepare and the commit. In this case, Oracle
holds the various locks it needs to commit the transaction, and when
WLS is restarted it doesn't seem to inform the XA resources that the
transaction should be rolled back/abandoned. Until a DBA sorts out the
problem, any attempts to use the locked areas (e.g. anything that does
a table scan or uses specific rows) result in errors of the form:
ORA-01591: lock held by in-doubt distributed transaction 18.65.2221
This is sensible as far as Oracle's concerned - it doesn't know if any
other XA resources committed or rolled back their transactions.
However, I'd have expected WLS, as the TM, to have sent the necessary
instructions to Oracle once the transaction has been recovered.
Nothing in WL's logs implies it's trying to do anything with recovered
transactions.
I've managed to make this repeatable. I have a class which I can send
a JMS message to kill the server. This MDB calls
Runtime.getRuntime.halt(1) (to simulate a serious crash) either during
the transaction (in onMessage()) or registers its own "XA killer"
resource which calls halt(1) in the prepare(). In the latter case I
always get an in-doubt transaction.
Anyone else had this behaviour, and more importantly, know how to
resolve it?
James

Lou,
any information about the results of testing of the patch from oracle for 'in-doubt
transaction' problem?
Thanks

Are you using Oracle817? Yes, we are.
There is a known Oracle817 bug that may be related to
your problem. You may try Oracle901.Ah. Such an upgrade would have major implications on our architecture.
Do you have any more information on this bug (a bug number etc)?
Would we have to upgrade the server, or just the clients?

Transaction on Oracle 9i data source connection times out before JTA transaction

Hello,
I have a MDB with a long-running transaction (3600 second timeout).
In the MDB, I make a call to another EJB that has its transaction
attribute set to NotSupported (I do this because I need
non-transactional semantics in the called method).
If the EJB call take more than about a minute to complete, then I get a
datasource error when using the data source in the MDB after the return
(see error at bottom). However, if the call completes quickly, then I do
not get this error. It seems like the datasource connection somehow
times out, but I don't see where I can change this timeout.
pseudocode:
// timeout set to 3600 seconds
transactional MDB onMessage() {
// receive connection from Oracle BEA driver
// myEJB performLongOperation has transaction attribute
// set to NotSupported
String result = myEJB.performLongOperation();
// use connection from Oracle BEA driver
If the performLongOperation takes more than about a minute, then I get
the following error when using the connection after the operation:
Caused by: java.sql.SQLException: XA error: XAER_NOTA : The XID is not
valid start() failed on resource 'Oracle IDENT Connection Pool':

What logging implementation for distributed transaction on Oracle 8?

Hi,
I have a script running on Oracle 8 that accesses remote databases. I would like to create a transaction log that creates log entries in another table as the script progresses. I initially tried creating a logging procedure that used PRAGMA AUTONOMOUS_TRANSACTION but this failed because of this error message:
ORA-00164: autonomous transaction disallowed within distributed transaction
I can't set the transaction to read only as database updates are part of the script.
Is there another strategy that I could use to create the logs I need?
Cheers,
kj

Unable to enlist in a distributed transaction (Windows7, Oracle 11G R1)

Hi,
I have a .Net application running on Windows 7 x64 using VisualStudio2008 and Oracle 11G R1 32bit client
In it I call a webservice calling another webservice, this requires to use oramts that interfaces with Microsoft DTC. However I'm getting the following error when calling the service method:
"Unable to enlist in a distributed transaction"
I have checked the following:
- Ora MTS is installed
- DTC is running, the security settings allow AX transactions (in fact I just allowed everything)
- Network services have the permission to access oracle dlls
- The registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSDTC\MTxOCI contains the following: "OracleXaLib"="xa80.dll" "OracleSqlLib"="SQLLib80.dll" "OracleOciLib"="oci.dll" (not sure if this is right)
What is it I'm doing wrong ? Does this version of Oracle work correctly on W7 ?
By the way it works fine on Windows XP !
I've spend quite some time trying to find a resolution..
Thanks!

I think I answered my own question
It seems that MSDTC is not supported by Oracle 11G R1 on Windows x64 !
All Oracle Database components are supported on Windows x64 with the following exceptions:
•Oracle Services for Microsoft Transaction Server are not supported on Windows Vista. As a result, all Oracle Windows data access drivers on Windows Vista that use Oracle Services for Microsoft Transaction Server to enlist in Microsoft Distributed Transaction Coordinator (MSDTC) coordinated transactions cannot participate in those coordinated transactions. These data access drivers include Oracle Data Provider for .NET, Oracle Provider for OLE DB, Oracle Objects for OLE, and ODBC. Check OracleMetaLink for up to date information on Oracle Services for Microsoft Transaction Server certification with Windows Vista.

How to cancel a transaction in Oracle Lite 10g R3

Hi,
I have a publication with 7 publication items (updatables), Server wins in any conclict.
I made some changes in some records of the 7 tables of my oracle lite database.
I synchronize the changes, without any error messages, But I cannot find those changes in the tables in my oracle database (9i).
So, I check in the Mobile Manager, in the Data Synchronization/Repository/Input Queue.
I find the transaction #203 with all the publication items.
I also find an error in the "Error queue", It seems like there was a conclict in one of my publication items. So I choose the option "Take value from server", then the error disapear from the "Error queue". However, the transaction stay in the "Input queue".
I made other changes to the tables in the database lite, and then synchronize. But It seems like nothing happens, there isn´t any other transaction in the "input queue", and I cannot fin all the changes I made in my database (9i).
Can anyone help me????

Using Distributed Transaction with oracle 9i and VB

How to I get distributed transaction to work between a COM + object in VB and oracle using MSDAORA.1 driver? I keep getting the following error:
error number:
-2147168229
error description:
Cannot connect to the transaction manager or the transaction manager is unavailable.

Oracle 9i works great with VB.NET. I would recommend you to use Oracle Data Provider .NET (ODP.NET) as a database driver

for better performance and get full advantage of Oracle 9i features.

Unable to commit a transaction Using Oracle

Hi all,
I have created a JDBC System using the following link.
http://help.sap.com/saphelp_nw04/helpdata/en/ab/082484173ae045ab8dad8a41d33da3/frameset.htm
The JDBC Datasource is working absolutely fine , in my database actually autocommit is off , so i need to commit a transaction explicity , when i try using connection.commit() , it gives me the following eroor
Commit not possible , xadatasource.
Can any one provide the reason for this , and what is the alternative for the Same.
Points will be rewarded for helpful answers
Regards
Sara

Hi Sara,
Are you using XADatasource ?I think it is an issue (http://wiki.jboss.org/wiki/Wiki.jsp?page=ConfigDataSources)with that
try using this
DataSource Type :-ConnectionPoolDataSource
ClassName:-oracle.jdbc.pool.OracleConnectionPoolDataSource
just restart the service and use it in your code.

How to configure distributed transaction in Oracle Database Gateway for ODBC? (ORA-02047)

I am connecting from Oracle to another database server (MS SQL Server, DB2 the error message is the same) through an ODBC connection using Oracle SQL Developer. (This is how I set up)
I want to query the schema of a non-Oracle database using the data dictionary mapping of the Oracle Database Gateway for ODBC.
This works well:
select * from all_tables@katimssql;
But this doesn't:
create table alltables_mssql as
select * from all_tables@katimssql;
Output:
Error report:
SQL Error: ORA-00604: error occurred at recursive SQL level 1
ORA-02047: cannot join the distributed transaction in progress
ORA-06512: at "SYS.HS$_DDTF_SQLTABLES", line 58
ORA-06512: at line 1
Does anyone know the solution of this?
Thanks in advance,
Kata
Details:
Oracle Database 11g Express Edition Release 11.2.0.2.0
Microsoft SQL Server 2008 (SP2) - 10.0.4000.0 (X64)

initkatimssql.ora:
HS_FDS_CONNECT_INFO=katimssql
HS_FDS_TRACE_LEVEL = ON
HS_TRANSACTION_MODEL = READ_ONLY_AUTOCOMMIT
I tried these, none of them worked, the error message is the same.
HS_FDS_TRACE_LEVEL = off
HS_TRANSACTION_MODEL = SINGLE_SITE
HS_TRANSACTION_MODEL = READ_ONLY_AUTOCOMMIT
HS_TRANSACTION_MODEL = READ_ONLY

Hi Kata,
this won't work as the ALL_TABLES is not a table that exists in your SQl Server - instead it is a "mimicked" table. This means the gateway will check if you have on your SQL Server a table called all_tables and when there's no table it will start an internal mechanism to check out what sort of tables exist in your SQL Server database. So the gateway is starting internally another transaction to get details from the foreign database and DG4ODBC can't participate in distributed transactions at all. Instead of using all_tables you have to use a real SQL Server table like SQ Server sys.objects or sys.tables.
