TimesTen to Oracle AWT Transaction semantics

Hi,
I had a question with regard to the transaction semantics being maintained between TimesTen and Oracle during an asynchronous write through from TimesTen to Oracle. Assume we had a single AWT cachegroup on TimesTen to update a single table on Oracle.
If on TimesTen, we perform the following transactions -
1. Insert a row into the TimesTen cache group.
    Commit - end of transaction 1.
2. Update the same row on TimesTen.
    Commit - end of transaction 2.
3. Update the same row again on TimesTen.
    Commit - end of transaction 3.
The question is would the update to Oracle via AWT consist of 3 transactions(Insert followed by commit, update followed by commit and another update followed by a commit.) or would it happen differently? I believe that the ordering (inserts followed by update and another update) would be maintained. How about the transaction semantics?
To add further, the TimesTen version we are using is 11.2.2.4.11 running on 64 bit Linux machine. We have a two safe commit architecture, where we have two instances of TimesTen, a primary(active) and a secondary(standby) setup, with the AWT running of the secondary(standy) instance.
Any input would be very helpful.
Thank you!

Thank you very much Chris. Here's what our observation is -
We have TimesTen to Oracle AWT replication, followed by a Golden Gate replication(set to transactional mode) on the same Oracle table. The transaction done is as follows -
1. Insert a row into the TimesTen cache group.
    Commit - end of transaction 1.
2. Update the same row on TimesTen.
    Commit - end of transaction 2.
3. Update the same row again on TimesTen.
    Commit - end of transaction 3.
Now on the Golden gate end, we expect that we receive 3 separate messages/events to indicate that there were 3 separate transactions. However, what we observe is that we mostly receive 2 messages/events and sometimes only 1 message/event for the same transaction activities listed above.
Note that we also have an XLA subscriber on these tables and we get the 3 _COMMIT messages correctly, which I believe is indicative of the transaction being correctly persisted into TimesTen. However, since the Golden Gate output is unpredictable, I was wanting to know, whether AWT is smart enough or for efficiency purposes, merges two or more transactions into 1.
In our case, the results are varying out of Golden gate -
1. Sometimes, the insert followed by two updates were received in one event/message.
2. The insert was received in one event/message, followed by both updates in one more message.
Is it at all possible, the AWT is smart enough to merge transactions? I read this piece - Oracle TimesTen and others Oracle Technologies: Updatable cache and transactional order and I wanted your thoughts on the same.
Thanks a ton!

How to define transaction semantics for JMS Queues

Hi,
My scenario in Oracle Fusion Middleware 11gR3, SOA Suite, IDE: JDeveloper 11g is as follows:
First). receive a message from QueueA, Second). Using the message, call a serviceABC and send the same message into QueueB.
I created a syn-BPEL, configured two JMS Adapters(for accessing Queue A & B) and one webservice binding for calling serviceABC(Proxy service). Note: I created the two queues and a connection factory under JMS System Module. As two different external systems have to access QueueA and QueueB.
Now, when I execute the BPEL and ServiceABC gets faulted, the message is gettings consumed from QueueA and the same message is getting produced in QueueB.
My goal is to define a transaction semantics for my composite(syn-BPEL), such that, when ServiceABC or producing the message in QueueB fails. I retain the message in QueueA(basically, rolling back the message).
Options tried so far: 1). Created a scope for the three operations and added a compensationhandler to it and .2). XA Connection Factory is Enabled. Result: no luck:( still message from QueueA is getting consumed where as per my goal it should get rolled-back.
Please suggest your approach, I'll try out and post the outcome back.

Whats your architecture? Are you running your app on an application server? If so, are you in a servlet or EJB? You should be able to get the application server to manage your transactions for you in that case e.g. wrap all the JMS calls in an stateless session bean and give it Required in its transaction attribute of deployment descriptor.
If you're not on an application server, you need to get a transaction manager, either by putting your code in an app server ( with JBoss you can use its transaction manager without necessarily having to use EJBs or Servlets, but thats not tested as thoroughly as the container managed transactions, and you will have to write some of the transaction code yourself ) or using a stand alone one.

Oracle Timesten with oracle apex

I use Oracle 11gr2 and apex 4.2.4 how can i use oracle timesten with oracle apex?
I want to use timesten to improve performance on report by adding two tables to oracle timsten.

As far as I am aware, recent (11g onwards) releases of Oracle Heterogenous services do not work with TimesTen as they now require an OBC 3.x driver and the TimesTen driver is currently 2.0. Even if they did work, this would not be a useful solution. It might allow Apex to access TimesTen after a fashion (though that is far from certain) but the performance would be very poor due to all the network hops and software layers between the application and TimesTen.
If you put one or two tables in TimesTen then one problem from an Apex perspective is that it is now dealing with two databases; the TimesTen cache containing two tables and the oracle database containing all the other tables. Is Apex designed to cope with this? Does it have the concept of data located in multiple databases where one of them is not the Oracle database? Also, do you need transactions or queries (joins) that span the TimesTen tables and the tables in Oracle DB? If so then this also will not work as that is not possible today.
I have to say that as far as Apex goes I think this is likely a non-starter. However, if you do try it and have any success then please do post the results here as we'd be interested to hear about it.

What driver and DataSource for EJB transactional semantics?

Hi people.
Joe Weinstein clarified a point that should be much clearer in the online docs:
"If you want EJB transactional semantics, you must use a TxDataSource."
I'm not clear about the relationship between TxDataSource and XA-drivers. I want
transactional EJB semantics.
So I must use TxDataSource.
Must I use XA-enabled drivers too?
What drivers can I use for Oracle?
Thanks, Alex

Hi Alexander,
You need to use XA driver in case you need truly distributed
transactions (spanning multiple databases instances).
Otherwise you could use non-XA driver with TxDataSource.
weblogic will simulate XA behavior. It will work for single
db instance.

Offline Data Transaction Semantics and Attachments

I'm researching migrating an existing web and mobile application to Azure. Currently, we're using a NoSQL solution that syncs to SQLite on the client and maps local documents to model subclasses similar to Core Data in iOS. Offline support is a key differentiation
in our market, so I'm focused on the detailed mechanics of sync.
One of our current pain points is that documents synced on both on the server and client do not arrive in a transaction. To use an example, if the iOS client created 10 Projects, each with 5 related Tasks, the first Project might be synced to the server
and trigger an event to process its related Tasks before the remaining Projects were inserted and the Tasks table even started syncing. This would cause processing to fail as the related Tasks were not yet available in the database. Since it appears that syncing
rows, some of which had conflicts, can result in only some of the rows being inserted, I'm under the impression server side inserts do not occur in a transaction, even at the scope of a table. Would this be accurate conclusion? If not, what are the transaction
semantics with offline sync?
Also, is there a strategy for syncing related binary content offline? For example, in our current system, each document can have n-number of media attachments that are synced as part of a multi-part request. However, it appears we would either need to store
related media as blobs in a table column or roll our own method of synchronizing related files as rows were pushed and pulled if created on the device while offline.
Thanks,
- Scott

Hi
Thanks for the update.
Good to know the different ways to do it.
Not sure if this fits in workflow forum too. as the question is primarily around the data handling and storage of attachments and documents.
Hence I close this thread in this forum, And created the thread in 'Workflow forum ' to get to know the response.
New Thread : Webforms - data handling and storage
Please update your thoughts in the new thread. Appreciate your time and effort.
Thanks alot.

Enable Oracle XA Transaction Support

Hi everybody. First of all, sorry for my terrible English.
I've been some problems using COM+ with Personal Oracle 8i (8.1.7.0.0) and SQL Server 2000 and Windows 2000 for development only.
I have one method that inserts the same data both SQL Server and Oracle (the tables and procedures definitions are identical) and I'm utilizing GetObjectContext method to commit or abort the transactions (the COM component were made in VB). Out of COM+ environment the method works 5x5. The error message is: "-2147168229 - Cannot connect to the transaction manager or the transaction manager is unavailable."
Checking Microsoft documentation I found an article (http://support.microsoft.com/support/complus/mtsandoracle.asp) telling me to "Enable Oracle XA Transaction Support" so I could have transactional work with Oracle and COM+. OK, just fine.
Does anyone knows how could I manage it? I am not a DBA nor I know one (an Oracle DBA), but I shall explain to my team how program 2 phase commit between Oracle and SQL Server.
Thanks in advance, and forgive me the size of this "book". I should be shorter next time...

Vivek, thanks for the help.
I am utilizing these versions of Oracle Products:
Personal Oracle8i Release 8.1.7.0.0 - Production
With the Partitioning option
JServer Release 8.1.7.0.0 - Production
Net8 Client 8.1.7.0.0
Oracle Services for MTS 8.1.7.0.0
Oracle Provider for OLE DB 8.1.7.2.0
The provider I first tried was MSDAORA with no success and then ORAOLEDB with no success too.
But those entries in registry that you sent me were all with Microsoft dll`s. I will try again tomorrow and send you the results
Thank you again
<BLOCKQUOTE><font size="1" face="Verdana, Arial, Helvetica">quote:</font><HR>Originally posted by Vivek Raja:
Renato, firstly what is the interface you use to access Oracle from your COM+ components? If it is OLEDB which provider is in use - MSDAORA or ORAOLEDB? What are the versions in use 8.1.6 or 8.1.7? If you are using MSDAORA as the provider then you will need to add the following key to your registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSDTC\MTxOCI.
Under this key add the following registry string values:
OracleOCILib - oraclient8.dll
OracleXALib - oraclient8.dll
OracleSQLLib - orasql8.dll
If you are using ORAOLEDB as the provider install Oracle Services For MTS 8.1.7. The error you receive seems to point to the fact that the "Distributed Transaction Coordinator" Windows2000 Service is not running.<HR></BLOCKQUOTE>

Hi,

This site is now up for nearly one year. We're using Oracle 8.1.7, Apache 1.3.24 and Tomcat 4.0.3. We've got about 4500 hits per day with a maximum up to 9000 hits.
Regards Uwe Hi there Uwe,
Given you are running this in a production environment, are you running the XSQLRequest object or are you running the servlet directly. Running the servlet directly in particular, is just not production ready, unless I am missing something.
1. There are no direct filesystem logging capabilities in the servlet. Doing inserts into a db table for the purposes of logging, is not adequate as the critical points in the servlet operation is either connecting to the database or in the post query phase during the xml transform.
2. Errors like invalid db connections, timeouts, invalid xsql/xsl files, ie All xsql-xxxx errors other than query errors are not trappable from the servlet either via xml or otherwise. They get written directly to the Output stream as text.
Using the XSQLRequest object programmatically, we can work around some of these limitations, but that defeats the purpose and the otherwise ease of use of this servlet in a XML envirnoment.

Handling update conflicts or overwriting of records from timesten to oracle

Hi Chris,
My question is this that I have read the documentation and found out the following:-
An update is committed on a cache table in an AWT cache group. The same update is committed on the cached Oracle table using a passthrough operation. The cache table update, which is automatically and asynchronously propagated to Oracle, may overwrite the passed through update that was processed directly on the cached Oracle table depending on when the propagated update and the passed through update is processed on Oracle.
To handle or to restrict this what is the option with which I can go because I want this as an exception that is to be handled but not to be ignored or overwritten by Timesten in database.
Moreover, I want to work with AWT cache group preferably.
Can you please help me with this part.

Chris,
First thanks for showing your interest:-
Let me explain it to you with different example:-
On two separate data stores (DS1, DS2), there is an AWT table for the same Oracle base table. A row is updated on DS1 and is committed. A row is updated on DS2 and is committed. Because the cache group behavior is asynchronous, the change on DS2 may be applied to the Oracle database before the change on DS1, resulting in the DS1 change overwriting the DS2 change.
I want to handle this overwriting so that I will be able to know which record is overwritten by which new value.
Or there is one more scenario:
If at some time my TimesTen is not connected to oracle database but I have the table cached in my TimesTen and some update is done on it for particular record and the same record is updated in the oracle database also with some different value then whenever I will connect my timesten to database it will overwrite the value which is updated earlier in database.
I hope now that you are able to understand what I am trying to do here.
Please suggest me some method to handle all these things.
Thanks for your support.

XML Publisher and the Oracle Shipping Transactions Form

I am running 11.5.10.2. I need to print Simplified Chinese characters in a document. We converted to the UTF-8 character set so the server can render these on forms and such. I am using Oracle Reports 6i to produce a report, but due to the limitations with this product it will not produce PDF output with Chinese characters. XML Publisher however works great. The concurrent manager is set so the report produces XML which is then set to the template and out comes a really cool looking layout with Chinese that can be viewed, printed, or e-mailed anywhere.
Now I have put this report into a document set so it can be printed from the Shipping Transactions form. But it does not work. There is no output. Metalink Note:312194.1 states development only supports XSL-FO and this will not be available until R12.
Is this really true? Has anyone else come across this? Any suggestions on how to get around this?

Hi
Im assuming you are using the EBusiness Suite becasue of your reference to AR and AP modules. If so getting using an ORacle Report as a datasource for XMLP to format is pretty straightforward. There is a white paper on metalink describe the complete process - Note 295409.1. This will be available on the public site soon http://www.oracle.com/technology/products/applications/publishing/index.html
As for AR and AP, there is no reason at all why you can not use XMLP with the existing Oracle Reports in those modules. You will start to see more and more modules providing embedded reporting functionality in the EBS based on XMLP technologies.

Tim

Correlation in Oracle B2B Transactions

Hi All, I am trying to find how do we co-relate EDI transactions when used Generic File as protocol.
Outbound Scenario:
When an EDI transaction is sent to a Trading Partner and if the host is expected to receive a TA1 acknowledgment from Trading Partner, how do we ensure the TA1 sent by Trading partner is related to the EDI transaction sent by Host.
Please advise...

Correlation with TA1 works on the basis of Interchange Control Number. Element I12 of TA1 contains the Interchange Control Number on the basis of which Oracle B2B correlates it with the corresponding request.

In documentation I didn't find any information about supporting by Timesten connects to Oracle 11g. So is Timesten can be connected to Oracle 11g or not? Now I've connected it but I'm not sure in proper work of this pair.

TimesTen 7.0.3 Cache Connect to Oracle supports Oracle 11g on Linux x86 (32-bit).
Additional platforms will be certified in upcoming maintenance release.
What platform are you using?
