Passivation and PS_TXN table - (Oracle ADF 11.1.1.6)

Hi All,
Can anyone help me understand the relationship between passivation and PS_TXN table insert? I am testing my application in a controlled environment using following steps -
(1) I truncated PS_TXN table first.
(2) I ran my application and visited couple of pages.
(3) I queried PS_TXN table and it has 22 rows in it
(4) When I check in enterprise manager ADF performance page the number of Passivations per min still shows 0 rows for all of my AMs.
What else could cause inserts in to PS_TXN table?
Thanks
Chetan

Query regarding passivation and PS_TXN tables

Hi All ,
I am working on a read only Dashboard UI where the DB user has only read privileges.
The jbo.server.internal_connection uses the same DB connection to create PS_TXN & PS_TXN_SEQ tables which fails for obvious reasons & I get the error -
"Couldnot create persistence table PS_TXN_seq".
I have disabled passivation at all the VO levels and also disabled jbo.isSupportsPassivation to be false at the AMLocal level , but still I am getting this error.
I have also increased the initial AM pool size in bc4j.xcfg & Connection Pool at the weblogic server level to avoid snapshots been written to this table.
Is there any way I can prevent any interaction with this table as the client too is not interested in any kind of passivation to happen for the time being.
Thanks

Thanks for your reply Chris.

You might be taking the wrong approach to solving this. Rather than disabling the AM pooling (which btw is not supported by Oracle) to the database, instead you can get ADF to passivate to file or memory of the app server.I am confused as to what exactly jbo.ampool.issupportspassivation = false does then ? I read on one of the blogs that its a viable use case for Programatic VOs ?
Also regarding passivating to file system as per http://download.oracle.com/docs/cd/E12839_01/web.1111/b31974/bcstatemgmt.htm#ADFFD1307 , its not really a recommended approach.. hence was not going for that.
Can you please throw some more light ?
Thanks

Bc4j and PS_TXN Table

Hi,
Reading the article "Understanding Application Module Pooling Concepts and Configuration Parameters" from Dive into Bc4j Blog; http://radio.weblogs.com/0118231/stories/2003/12/17/understandingApplicationModulePoolingConceptsAndConfigurationParameters.html
The jbo.passivationstore, parameter sets where we want to store Bc4j's Xml snapshots ( files on disk or Database ).
Bc4j AM, uses PS_TXN table to store it's states between sessions calls.
Querying this table at an dummy database schema just to see how many rows, i realize that it has almost 7.000 rows .
Application Module Pool does not have any parameter to configure a garbage collection over Ps_Txn or the disk file ?
I mean, as it is a dummy schema the application module pool, never will restore any state stored there, how it's works ? When can we clean all that rows ?
thanks.

Passivation store parameter controls all passivation, including what is written to PS_TXN when you opt for the (Default of) database passivation.
BC4J should clean up the snapshots when the AM is released in stateless mode, or when the session expires.
If sessions are killed, we supply a script in ./BC4J/bin/bc4jsession.sql to clean up the info in that table at whatever interval you would like to.

Which is better as UI technology among Flex and Oracle ADF for oracle SOA suit

We have one application which is using oracle’s Service oriented Architecture (SoA) suite. Currently, there is a debate on the technology for UI in the new architecture that will be rich, easy to maintain, scalable and integrates well with SOA suite. We have two options one is Flex and other is Oracle ADF. UI part contains number of graphs, tabular and charts data. So it would be great if any one suggest which technolgy will be better for UI point of view. Thanks in advance.

Hi,
I looked at the demo
http://download.oracle.com/otn_hosted_doc/jdeveloper/11gdemos/ADF112/ADF112.html
It's interesting.
However, I would point out two things:
1- Before Oracle, Sun failed with UI technologies: there was AWT then Swing then Java FX. None of them was a star. The only place where Sun really won the UI war is the Bluray Disc format.
2- About half of the RIA in the financial/banking industry are developed with Flex, the other half is developed with Silverlight / WPF. HTML 5 is being taken up by some, but you still end up with the usual problem of having to pick up an AJAX framework, and get tied to a vendor anyway in the end. Never heard about any project developed with Oracle ADF yet.

Oracle ADF Business Service Layer Technologies

Hello,
We are building an online shopping mall/site that is expected to receive order volume of 50-60 thousand orders per week. So obviously, data traffic generated by the site will be pretty heavy. The technology set we are supposed to use is Jdeveloper 10g with ADF. Currently ADF business service layer offers following set of technologies. The question is which of following technologies meets these four criterias the BEST? (1) Security, 2)24x7 Reliability and Maintenace overheads (3)Speed /Performance of the server response to client requests (4) integration with Oracle database.
Please advise. Any technet/metalink oracle document that compares these various business layer technology would be great indeed.
Business service technologies that I am talking about is mentioned below
Enterprise JavaBeans (EJB) Session Beans
Since most J2EE applications require transactional services, EJB session beans are a logical choice because they offer declarative transaction control. Behind the EJB session bean facade for your business service, you use plain old Java objects (POJOs) or EJB entity beans to represent your business domain objects. JDeveloper offers integrated support for creating EJB session beans, generating initial session facade implementations, and creating either Java classes or entity beans. You can also use Oracle TopLink in JDeveloper to configure the object/relational mapping of these classes.
JavaBeans
You can easily work with any Java-based service classes as well, including the ability to leverage Oracle TopLink mapping if needed.
Web Services
When the services your application requires expose standard web services interfaces, just supply Oracle ADF with the URL to the relevant Web Services Description Language (WSDL) for the service endpoints and begin building user interfaces that interact with them and present their results.
XML
If your application needs to interact with XML or comma-separated values (CSV) data that is not exposed as a web service, this is easy to accomplish, too. Just supply the provider URL and optional parameters and you can begin to work with the data.
ADF Business Components.
These service classes are a feature of the ADF Business Components module, and expose an updateable dataset of SQL query results with automatic business rules enforcement.
Thanks
Ruchir

So the quote says "technologies Oracle recommends to J2EE developers" which is correct - if you are an experience Java EE developer the TopLink/JPA/EJB stack should be your choice however if you are coming from a 4GL/Enterprise developer background then the recommendation is here:
http://download.oracle.com/docs/html/B25947_01/intro002.htm#sthref21
For enterprise 4GL developers building new web applications, Oracle recommends using JavaServer Faces for the view and controller layers, and ADF Business Components for the business service implementation. This combination offers you the same productive J2EE technology stack that over 4000 of Oracle's own enterprise 4GL developers use every day to build the Oracle E-Business Suite. Since its initial release in 1999, several thousand external customers and partners have built and deployed successful Oracle ADF-based applications as well. Both now and in the future, Oracle and others are betting their business on Oracle ADF with ADF Business Components.
And yes ADF BC can be exposed as EJB - but this is usually only used for remote deployment of ADF BC when they are on another server than the UI code - for example when using Swing.

Display and edit currently selected row of ADF Table in ADF Form

I have an ADF Read-only Table and ADF Form, which were created from the same Data Control.
I need to be able to edit the selected row of the table in the form (just like in "Binding Data Controls to your JSF page" part of "Developing RIA Web Applications with Oracle ADF" Tutorial). However, I can't figure out how to do this :(
I found the following solution on the Web: #{bindings.DeptView1.currentRow.dataProvider.dname} - but it doesn't work, since "the class oracle.jbo.server.ViewRowImpl does not have the property dataProvider".
Sorry for the newbie question.
Thanks in advance for any help!

Hi,
AFAIK, dataProvider is not supported on ADF BC, hence the error.
If you have created ADF Read only table and form from the same data control you just need to refresh the form based on table selection to show up the selected record, to do which you just need to add partialTriggers property to the panelFormLayout and set its value to the id of table

Oracle ADF and ECM workflow

Hi,
I'm looking for ideas on how to implement this which will involve using Oracle ADF and ECM Workflow.
1. Oracle ADF App that will check-in an item into ECM.
2. Using Oracle ECM workflow, an email is sent to the manager that a item has been checked in and is ready for review. The manager access the ADF app , clicks on a "Awaiting approval" and reviews the doc(in an iframe), makes comments(if possible) and then approves it in which case it is published or rejects it in which case it sent back to the employee.
3. I found a similar posting to this Re: Custom pages at each workflow step in UCM
Thoughts, ideas?
Thanks.

Everything, from checking in, to get a list of approvals, is available by services. You can call the service from an ADF and use the result of that service as a dataset to use in a table. In the administration menu, there are WSDL descriptors for each part for example the check in service, the search service, the workflow service,...

Hi timo,
Thanks for ur reply...
we are using unbounded taskflow.
In Controller class(page def file), we refered the class that implements PagePhaseListener
The following override methods has created
public void afterPhase(PagePhaseEvent pagePhaseEvent) {
//In this area we used to read the session object file which is written and sent by another application(application to application navigate).
If session object file exists,will allow the user to navigate into the requested page else will navigate in to login(security aspect).
public void beforePhase(PagePhaseEvent pagePhaseEvent) {
Is we used Controller class wrongly ???
Is there any relationship with region controller???

How to create a JSF page wich filter a Table, similar to an ORACLE ADF LOV?

I want to create a JSF Page with a table and filtering capabilities similar to ORACLE ADF LOV(List Of Values) (or similat to ORACLE Forms LOV)
So, we have a page wich contain a Table and a text field and search button.
The field will contain the search criteria and the button will submitt the search.
The search criteria shoult be applied on a table column and the result be rendered.
An example can be : http://technology.amis.nl/blog/?p=1933 realized in Oracle ADF technology.
Can anyone find a similar example in JSF/Netbeans ?
Thanks!

To realize a LOV may be usefull a filter on the table:

Best Practice to fetch SQL Server data and Insert into Oracle Tables

Hello,
I want to read sqlserver data everry half an hour and write into oracle tables ( in two different databases). What is the best practice for doing this?
We do not have any database dblinks from oracle to sqlserver and vice versa.
Any help is highly appreciable?
Thanks

Well, that's easy:
use a TimerTask to do the following every half an hour:
- open a connection to sql server
- open two connections to the oracle databases
- for each row you read from the sql server, do the inserts into the oracle databases
- commit
- close all connections

Hi all,

When and why should we use Oracle?I suggest that you start here:
http://www.oracle.com/technetwork/database/nosqldb/overview/index.html
Is Oracle NoSQL database link with Big Data Appliance?Yes, Oracle NoSQL Database will be a component of the Big Data Appliance.
Can we use map-reduce on a single personal computer? How should we install Oracle NoSQL database to use map reduce on a single personal computer?Yes, I believe you can run M/R on a single computer. Consult the various pieces of documentation available on the web. You may run Oracle NoSQL Database on the same computer that you are running M/R on, but it is likely that they will compete for CPU and IO resources and therefore performance may suffer.
Do we also have eventual consistency with Oracle NoSQL database? Yes.
Can we lose data if master node fails?If you run Oracle NoSQL Database with the default (recommended) durability settings, then if the master fails, a new one will be elected and data is not lost.
Are transactions ACID with Oracle NoSQL database? How can we prove it?Yes, each operation is executed in an ACID transaction. The API has the concept of "multi" operations which allow the caller to perform multiple operations on sets of records with the same major key, but different minor keys. Those operations are also performed within a transaction.
