Global Transaction Purge

Hi,
I have few questions related to Global Transaction Purge Program in Inventory:
1. In which Scenario or Situation we need to run these Program?
2. While executing the program, if any performance issue what will be DBA activity?
3. What is the best time to run this program?
4. What are the constraint which we take into account before running the program?
Please share your thoughts about it.
Thanks

Refer MOS note: Inventory Purging Programs Information (Doc ID 1351271.1)
you will get answer to your all questions.
thanks

Advise on using DBMS_XA with multiple branches under one global transaction

Dear all
I need some advise on using DBMS_XA from PL/SQL with tightly coupled multiple branches under one global transaction. Basically, I've successfully written some PL/SQL code that in 3 different sessions attaches to 3 different branches of one global transaction and before ending each branch they can see each others uncommitted data. So far so good.
However, I'm not sure I completely understand how each branch must call xa_end, xa_prepare and xa_commit correctly using two phase commit and my calls result in errors like:
ORA-24767: transaction branch prepare returns read-only (XA error code 3 = Transaction was read-only and has been committed)
ORA-24756: transaction does not exist (XA error code -4 = XID is not valid)
ORA-02051: another session or branch in same transaction failed or finalized
This is the structure of my programs (3 SQL*Plus sessions):
main: Uses xid 123|0 (branch 0 of global transaction 123). This should be the coordinator that commits using two phase commit across the 3 branches
m1.xa_start tmnoflags
m2.DML
m3.Wait for thread A + B to manually be started and run xa_end
m4.xa_end tmsuccess
m5.xa_prepare
m6.xa_commit false
thread A: Uses xid 123|A (branch A of global transaction 123)
a1.xa_start tmnoflags
a2.DML -- thread A can see main and thread B's data
a3.xa_end tmsuccess
a4.xa_prepare -- required?
a5.Should we also call xa_commit false?
thread B: Uses xid 123|B (branch B of global transaction 123)
b1.xa_start tmnoflags
b2.DML -- thread B can see main and thread A's data
b3.xa_end tmsuccess
b4.xa_prepare -- required?
b5.Should we also call xa_commit false?
The failing steps are:
m5
m6
a4
a5
b4
b5
Before starting calling xa_end I see 3 rows in V$GLOBAL_TRANSACTION, eg (hex 7B = decimal 123):
FORMATID GLOBALID BRANCHID BRANCHES REFCOUNT PREPARECOUNT STATE FLAGS COUPLING
203348753 0000007B 00000000000000000000000000000000 3 3 0 ACTIVE 0 TIGHTLY COUPLED
203348753 0000007B 0000000000000000000000000000000A 3 3 0 ACTIVE 0 TIGHTLY COUPLED
203348753 0000007B 0000000000000000000000000000000B 3 3 0 ACTIVE 0 TIGHTLY COUPLED
Thanks a lot in advance.

OK, I've figured it out. This is poorly documented as it's not well explained how to handle the various return codes. Turns out that all but the last xa_prepare calls return dbms_xa.xa_rdonly (tightly coupled branches are combined -- "read only" optimization), the last one returns dbms_xa.xa_ok and this is when you should call xa_commit.
Now my next problem is that DBMS_XA doesn't work from within jobs (DBMS_JOB and DBMS_SCHEDULER), which makes it very difficult to use DBMS_XA. My purpose of using DBMS_XA is to coordinate work across multiple sessions in one transaction but if I can't easily create the multiple sessions, I'm stuck.
When called from a job, xa_start throws:
ORA-24789: start not allowed in recursive call
on Oracle 11.2. In Oracle 11.1 it works, but xa_end fails with
ORA-25352: no current transaction
so I guess in fact the xa_start call didn't really work either, even though it returned tm_ok.
I'm now trying to find a workaround on how to use DBMS_XA from within jobs, please comment if you have any suggestions. Or if you have any suggestions on other means of establishing the concurrent sessions (I wouldn't like to resort to external programs that need username/password to connect as password management would be a security issue).
Thanks in advance.

The method 'commit' cant be called when a global transaction is active.

Hello,
I've installed the SOAdemo a couple of times on local machines, and it works fine. Now I've deployed the SOADemo on a separate server and a strange error occurs in BPEL when testing the SOADemo.

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.

Hi,
Try switching the order of logging the error message and the DISPLAY of TPSTATUS in the IF NOT TPOK sentence following the CALL of TPCALL. I believe the call to USERLOG is overwriting TPSTATUS so what you are seeing is TPOK from the USERLOG call and not the original status from the TPCALL. Hopefully this will allow you to see the actual error status from the TPCALL.

How 2 avoid a Non-XA resource from listing in Global Transaction?

<pre>
Hey,
I am using container managed transaction in a stateless session bean. We are using two datasources, one xa and non-xa. I am using these two datasources in a single transaction and i am getting an exception that both can't participate in the same transaction.
Is there a way that I don't want to enlist my non-xa resource with transaction manager?
I have come across the following approach.
I have seen Simulate Two Phase for Non XA, but you are saying to be careful with this option as for Example, Non-XA and XA says OK during prepare phase(phase I) and then XA resources decides to roll back in phase II, Non-XA can't revert as it is already commited,
But I have also come across LAST PARTICIPANT NON-XA along with mutliple XAs option in websphere, like this if I update my Non-XAs in the end, will WEBLOGIC takes care of all XAs and Non-XAs as single atomic operation or it does partially ???
Appreciate your help.
Thanks,
Rao Kotha.
</pre>

You can make the non-XA driver based data-source 'not to honor the global
transaction'. Which version of weblogic are you using?
By default, when you create a data source, it is a TxDataSource (it honors
global tx). In the console, there is a check box to disable the default
behavior which will make the data source not to participate in transactions.

MQ message is not coming back in MQ in case of error in Global Transaction

Hi,
```````````````````````````````````````````````````````
I am using Oracle JDeveloper 11.1.1.5.0 and SOA server 11.1.1.5
```````````````````````````````````````````````````````
Use Case :_
I have created a Sync BPEl process. In which I am dequeing the messages from MQ using "Get Messages from MQ" Operation available in MQ series Adapter. Also checked the Synchronous check Box, So that we can have the Ondemand dequeing of Messages.
Three Properties have been added In Composite.xml file to make the MQ adapter service participate in Single global transaction :
<property name="*bpel.config.transaction*">required</property>
<property name="*bpel.config.oneWayDeliveryPolicy*">sync</property>
<property name="*partnerLink.SyncReadMQ.transaction*" type="xs:string" many="false">participate</property>
(this last property is added in the partner link of the MQ series adpater, And hence refleacted in the composite.xml file)
Also provide the MQ Adapter configuration XATransaction='true' in Admin console, to support the Global transaction by following the Oracle Doc (http://docs.oracle.com/cd/E17904_01/integration.1111/e10231.pdf)
Issue :_
In case of any system error, The Message is not going back into the MQ and it is lost. My concern is that if I have made the MQ adpater service to participate in the global transaction of the Main BPEL process then upon any fault occur the Adapter service should be rolled back. but it is not happening.
I want the message back in the Queue in case of any error.
Would anyone please help me in this issue.+
`````````````````````````````````````````````````````````````````````````````````````````
One more thing to notice is that MQ Adapter is a transactional adapter it should participate in the rtransaction.
`````````````````````````````````````````````````````````````````````````````````````````

Hi All,
Still this thread is unanswered, Is there any genius who has done Transaction handling on Adpaters (MQ or JMS). I have look into may threads on forums, but no appropriate information is given about this issue. If this thread is been answered then it will be very helpfull for othes dealing with transaction in MQ.

SQL operations are not allowed with no global transaction by default for X

Hi All,
I am getting the above mentioned error.
java.sql.SQLException: SQL operations are not allowed with no global transaction by default for XA drivers. If the XA driver supports performing SQL operations with no global transaction, explicitly allow it by setting "SupportsLocalTransaction" JDBC connection pool property to true. In this case, a
lso remember to complete the local transaction before using the connection again for global transaction, else a XAER_OUTSIDE XAException may result. To complete a local transaction, you can either set auto commit to true or call Connection.commit() or Connection.rollback().
I am developing a web application. I have jsp, servlets, JDBC classes.
I am using DataSource and Connection pools.

Can the ApplicationModule support global Transaction for multi db instance?

purpose:
I want to update data in two db instance .
pre-conditions:
I create two application module , in the two application modules ,one is root application module. one application module connect one db instance, the other application module connect to the other db instance.The two application modules include entity objects and view objects which map the tables in the two db instance.
In the jsp page , I bind two view objects , one view is owned by root application module ,the other view object is owned by child application module and the two view objects map the two tables which are in different db instance .the view objects binding style in the jsp page is input-form.
The result:
while the input-form is submitted ,the error occurs.The global transaction isn't committed, why?

A nested application module instance uses the transaction/connection of its parent.
The simplest way to accomplish what you're trying to do is to use Oracle database DBLinks so that the two-phase commit is handled at the database level.
ADFBC does not support two-phase commit at the application level between two separate root application module's transactions.

Global transactions in OSB and EJB 2.1

Hi,
My team is working in a SOA service based on OSB 11g (11.1.1.5) using DB JCA Adapter and EJB 2.1 over WLS 10g(WLI environment). The logic of the service works in this way:
1. A table in a database (XE) is polled by the DB Adapter which starts the service (1 row = 1 message).
2. The message contains a collection of items to be inserted in another Oracle database.
Once a message/row is picked, and after some steps (logging, validation,etc), there is a for..each action which extracts each item of the collection and executes a service callout action to a business service.
3. This business service uses EJB protocol to call an EJB (2.1 + WLS Extensions). The EJB is deployed in another domain (WLS 10.3.0/10g and Oracle BEA drivers) and only executes an store procedure with the parameters based on the message and inserts these values in a table.
4. Once the for...each finishes, there is a call to another proxy service which marks the message/row as "processed" in the source table. This update is done via DB JCA also.
5. In case of an error, the error handler of the proxy service calls the proxy service mentioned above to mark the row as "Failed" (in fact there is a retry mechanism, but it's not important for now).
The service requires to work inside a global transaction. The main requirement is that the collection of items should be processed as "All or None", so basically we're using the options to manage the global transaction. However, the problem is that it's failing to rollback the whole insertion of items when an error is simulated. It only rolls back the last insertion/execution of SP.
Additionally, the proxy service that should mark the row as FAILED, never updates this one, and the tables stay locked until we modify one of the store procedure in order to avoid the simulated error and commit the transaction.
The EJB uses WLS extensions with the annotations to "transaction required". The proxy service has the option transaction required also. The database drivers are all XA and we're testing against Oracle11g XE (however, the EJB destiny will be Oracle 8i in production).
We have tried different alternatives, splitting the logic in different proxies (Proxy services for JCA, Proxy with For Each for EJB, etc), isolating the specific part with the EJB call, without success.
The security between domains is set as Global Trust.
Do you have any idea, example or suggestion about this problem? Is EJB really supported in Global Transactions and XA?
Thanks in advance.

where do you find the J2EE Connector 1.5 compliant
Resource Adapter?I wrote the compliant adapter myself. Hey Steve,
Were you able to find a solution for this problem. I am struggling with the same problem with the RI Beta implementation.

E-Business Suite apps_initialize and SOA Global Transactions

Hi,
We are developing an integration which sends data from one system to an Oracle E-Business Suite instance. In order to load the data into E-Business we need to call API’s which require the fnd_global.apps_initialize to be run.
We have a custom PL/SQL procedure which calls the API
e.g.
SOA -> custom PL/SQL -> E-Biz API
The custom PL/SQL runs apps_initialize.
The problem is when we call this from SOA via a XA connection we get the following error:
<P_ERR_MESSAGE>Error - Failed to delete the interface records after reading result! Message: Unknown Error ORA-20001: Oracle error -20001: ORA-20001: Oracle error -2074: ORA-02074: cannot SET NLS in a distributed transaction

</P_ERR_MESSAGE>
The main error here is cannot SET NLS in a distributed transaction.
This is caused by fnd_global.apps_initialize running SET NLS commands in order to do it’s thing.
We are looking to use the functionality of global transactions in order to achieve reliable messaging.
Does anyone have any experience with calling custom PL/SQL from SOA XA connections?
Robert

Robert,
I have the similar use case. I am using a seeded Oracle API to insert data into the tables. I want the user information to be populated in the WHO columns (CREATED_BY, LAST_UPDATED_BY). I have mentioned the jca.apps.username and jca.apps.responsibility in the Invoke activity.
But unfortunately, the columns are not populated with the data. I am using the Oracle Apps Adapter to call the API.
Any inputs will be really helpful.
Thanks,
Sakthi.

How to set global transactions for XA.

Hello,
I have configured 9i RAC active/active database into a active/passive.
The users were not able to connect using XA drivers.
I have run the xaview.sql script as sys in @O_H/rdbms/admin and granted select privs as below.
grant select on v$xatrans$ to public;
grant select on pending_trans$ to public;
grant select on dba_2pc_pending to public;
grant select on dba_pending_transactions to public;
Still users are not able to connect to the databases using XA drivers.
What is needed more to be set up on the database side?
Can any one let me know the detailed method to set global transactions(that is what I was told needs to be set up) on the oracle database.
Thanks
SKH

Further to give more info the error users are facing is
Could not connect to 'oracle.jdbc.xa.client.OracleXADataSource'.

Global transaction problem with JDriver/Oracle and Oracle XA

We are haveing serious problems with Container Managed Transactions on Bea 6.1
and Oracle with EJB having set "Required" for all methods. We have tried in vain
to make it work with JDriver as well as OracleXAClient. Both fail at sometime
during the execution throwing "Not called in cotext of global transaction" (with
JDriver) OR "XAER_PROTO : Routine was invoked in an
inproper context start() failed on resource 'OracleXAPool'" (this one with oracle
XA).
1.) Weblogic JDriver-XA:
DatabaseMetaData metaData = dataSource.getJDBCConnection.getMetaData();
ResultSet resultSet = metaData.getTables(null, null, tableName.toUpperCase(),
new String[]{"TABLE"});
This fails immmediately saying that it was not called from global transaction.
Interesting thing is that with OracleXA, it doesnt say this exception at this
check point.
2) Oracle XA
Okie, we couldnot read through the CLOB using it so for reading CLOB, we used
direct jdbc connection and then did away with it. Now all next sql queries were
executed against oracle pool using XA data source with OracleXAClient. But at
some point we again ran into the problem "XAER_PROTO : Routine was invoked in
an
inproper context start() failed on resource 'OracleXAPool'"
3 Oracle Thin Driver
everything always works with it.

AFAIR this issue was resoved by moving tx opreations out from non-tx
methods.

Jawad,
It would be nice if you can post the full stack trace error message. Didyou try moving to
the latest service pack (sp2) for WLS6.1.
Thanks,

Yes we had correctly set TXDataSource and let it to point to the right
connection
pool each time and it worked well with oracle thin driver but not whenwe switched
the pool to JDriver or OracleXAClient. Note that we could aways confirmthat pool
was successfully created alongwith we could retrieve connection from itvia TXDatSource,
things gave problem after we attempted to do what i had mentioned in mylast posting.

Also with JBoss 2.4.4 things work pretty well. So couldnt be our codeproblem.

Mix Local and Global Transaction using XA Driver for Oracle

Hi all,
We are trying to use a XA Driver which can support both local as well as global
transaction. We tried using the Weblogic jDriver (XA Driver) type 2 that comes
along with Weblogic installation but unfortunaltely it cannot mix local as well
as global transaction.
Please let me know in case we have any XA JDBC driver for Oracle Database which
supports both local and global transaction together.
Thnx,
Kumar
Environment:
Weblogic 8.1 server
Database used : Oracle8i

Most database drivers can support local and global transactions, with some
restrictions.
The JDBC spec has been changed to require compliant drivers to let the
application
know if they try to start a global transaction while a local transaction has
not been
completed (or vice verse). So most of the database drivers have been
changed to enforce
this restriction (breaking a lot of code that is out there).

Lookup-table and query-database do not use global transaction

Hi,
following problem:
DbAdapter inserts data into DB (i.e. an invoice).
Process takes part in global transaction.
After the insert there is a transformation which uses query-database and / or lookup-table.
It seems these XPath / XSLT functions are NOT taking part in the transaction and so we can not access information from the current db transaction.
I know workarounds like using DbAdapter for every query needed, etc. but this will cost a lot of time to change.
Is there any way to share transaction in both DbAdapter insert AND lookup-table and query-database?
Thanks, Best Regards,
Martin

One dba contacted me and made this statement:
Import & export utilities are not independent from characterset. All
user data in text related datatypes is exported using the character set
of the source database. If the character sets of the source and target
databases do not match a single conversion is performed.So far, that does not appear to be correct.
nls_characterset = AL32UTF8
nls_nchar_characterset = UTF8
Running on Windows.
EXP produces a backup in WE8MSWIN1252.
I found that if I change the setting of the NLS_LANG registry setting for my oracle home, the exp utility exports to that character set.
I changed the nls_lang
from AMERICAN_AMERICA.WE8MSWIN1252
to AMERICAN_AMERICA.UTF8
Unfortunately , the export isn't working right, although it did change character sets.
I get a warning on a possible character set conversion issue from AL32UTF8 to UTF8.
Plus, I get an EXP_00056 Oracle error 932 encountered
ORA-00932: inconsistent datatypes: expected BLOB, CLOB, get CHAR.
EXP-00000: export terminated unsuccessfully.
The schema I'm exporting with has exactly one procedure in it. Nothing else.
I guess getting a new error message is progress. :)
Still can't store multi-lingual characters in data tables.
