TopLink 9.0.4.5 and aggregate object mappings

We use TopLink version 9.0.3 to access Oracle database 9i with our application.
I currently evaluate TopLink version 9.0.4.5 with Oracle database 10g (10.1.0.3.0).
The problem we have is with aggregate object mappings.
After instantiation of the owning and the owned object, we set a back reference from the owned object to the owning object.
We then register the owning object at the unit of work with registerObject() and work on the returned clone.
After commit we read again the created data.
Using TopLink version 9.0.3:
The owned object has the back reference to the owning object.
Using TopLink version 9.0.4.5:
The owning object is valid but at the owned object the back reference is missing (null).
That's strange because we had no problems in the past (since TOPLink 2.1 up to 9.0.3).
What is going wrong here? Any idea?

How was the back pointer mapped in the TopLink project?
If you check your project from 9.0.3.X is there a Descriptor event listener with postBuild and postClone implemented?.

What are some uses for the aggregate object and definition file?

Can anyone share some examples for using the aggregate object in a Lookout process file? I've spent only a little bit of time with it, but I can't see how it provides any useful functionality. I guess I'm open to suggestions--thanks in advance! JT
John T. Sampson

If you want to reuse code in a modular sence than the Aggregate object will work. Although it works best to start the development with the intent to reuse that segment of code.
Look at the Sequencer Object Example from the Developer Zone. Follow the README file to copy all files into the Lookout/Examples folder. The Help_Template is an Aggregate process that was used many times in different examples for the web. The state file, .l4t, holds the text that gives further details on the development of the example. The Sequencer process has an Aggregate object used in it to open the Help_template.

Using Clob with TopLink 9.0.4.5 and Oracle 10g RAC

I am trying to store an XML file in a Clob type field of a DB table using TopLink 9.0.4.5 and Oracle 10g RAC and need some guidance about how to do it. I got some directions to start it with the Tip "How-To: Map Large Objects (LOBs) to Oracle Databases with OracleAS TopLink" but still need some more helps.
When using the Oracle JDBC OCI driver, the tip gives the code block for a Clob field:
DirectToField scriptMapping = new DirectToField();
scriptMapping.setAttributeName("script");
scriptMapping.setFieldName("IMAGE.SCRIPT");
descriptor.addMapping(scriptMapping);
As I understand, TopLink creates instances of the Descriptor class at run time for each of the descriptor files and stores them in a database session, where is the proper place (in SessionEvent of TopLinkSessionEventHandler?) for me to get a reference to such an instance of my Descriptor class in Java code so that I can add the above mentioned additional Mapping? Are the above String values of "script" and "IMAGE.SCRIPT" predefined in TopLink API? Can I accomplish the same thing just using the TopLink Workbench tool instead? If yes, please advise the detailed steps to do so.
The tip also states to call the following code in case of using Clob:
DatabaseLogin login = session.getLogin();
login.useStringBinding();
Should the above 2 lines of code be called after the following lines of code?
SessionManager sessionManager = SessionManager.getManager();
Server serverSession = (Server)sessionManager.getSession("MY_SESSION_NAME");
Besides the above extra coding for the Session and Descriptor Mapping, is there any special handling in between Data model and DB table mapping? Can I map a Java String type to a DB Clob field using the Direct-to-field mapping?
Appreciate any help.

Never mind ....... I had already figured it out .....

Toplink 9.0.4.8 and JTS on OAS 10.1.2.0.0 and 10.1.2.0.2 not rolling back

Re-Posting message with more information.
Toplink 9.0.4.8 and JTS not rolling back transaction
Hi
Scenario:
I have a session bean (EJB1) calling a session bean (EJB2).
When an EJB1 is called, EJB1 persists data on to Table1 in database.
And EJB1 makes multiple calls to EJB2 to create entries in three different tables. Trans-attribute is set as required on both EJBS.
Problem:
EJB1 gets a Runtime Exception while inserting the data into TABLE1 (ORA-12899: value too large for column), EJB1 transaction is rollback, but all other transactions related to EJB2 are getting committed. I assume that they should roll back too.
Also, I did JAD on external transaction controller and listener and noticed that there is a transaction associated to each call. Meaning EJB1 had Transaction T1 and EJB2 had T2, T3, and T4 for the subsequent calls. When EJB1 is getting runtime exception in the method beforeCompletion(), the it calls rollbackGlobalTransaction() which is calling T1.setRollbackonly(). But not on on T2, T3, and T4 rollback
Am I missing anything?

Toplink Helper class that is used by both EJB's
This one uses SessionBroker. here is how it is initialized:
SessionManager manager = SessionManager.getManager();
sessionBroker = (SessionBroker) manager.getSession(xmlLoader,
sessionBrokerName, this.getClass().getClassLoader());
Oracle9iJTSExternalTransactionController extController = new Oracle9iJTSExternalTransactionController();
sessionBroker.setExternalTransactionController(extController);
It has common following commong methods:
public UnitOfWork getUnitOfWork() {
UnitOfWork uow = sessionBroker.getActiveUnitOfWork();
return uow;
public Object create(Object o)
UnitOfWork uow = getUnitOfWork();
uow.registerNewObject(o);
// added so that the assigned sequence number will be available before the commit happens
uow.assignSequenceNumber(o);
return o;
}

A couple of this appear different in your sessions.xml. To do what you want you need to configure TopLink to:
1. Use an external XT controller - requires flag to be set and controller provided
2. Use the OC4J data source - requires flag to be set and data source name provided
I notice that your sessions.xml has both a data source name as well as a direct connection URL.
Here is a sample that shows the proper settings for the external TX and data source usage:

Doug, Andrei and others
I found the problem. I have a Delegate that provides access to all EJBS. This delegate is used by both the webtier and middle tier.It is written in a generic fashion so that the web server and middle tier does not have to be co-located in one container. getInitialContext() which is implemented as follows:
private static Context getInitialContext() throws NamingException
// Get InitialContext for Embedded OC4J.
// The embedded server must be running for lookups to succeed.
// actual code reads from the external parameters
String contextFactory = "com.evermind.server.rmi.RMIInitialContextFactory";
String principal = "admin";
String passwd = "admin123";
String providerURL = "ormi://localhost:3201/shc";
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, contextFactory);
env.put(Context.SECURITY_PRINCIPAL, principal);
env.put(Context.SECURITY_CREDENTIALS, passwd);
env.put(Context.PROVIDER_URL, providerURL);
env.put("dedicated.rmicontext","true");
return new InitialContext(env);
When the EJB1 tries to look up for EJB2, container thinks that the call is from outside the container and it is starting a new transaction.
When I changed the EJB1 to look up EJB2 to get the context as shown below,every thing seems to rolling back.
private static Context getInitialContext() throws NamingException
return new InitialContext();
Thanks again for pointing me in the right direction.
I will post the same message in other threads.

UnitOfWorkChangeSet and deleted objects

I would like use the UnitOfWorkChangeSet for auditing changes made to the objects. It seams that the UnitOfWorkChangeSet contains new objects and updated objects, but I cannot find deleted objects. The function UnitOfWorkChangeSet.getDeletedObjects always returns an empty set.
1) How to get deleted objects?
2) Where can I find the best information about usage of the change sets?
3) Can I process the change set after calling the method commit or is it better do it in any SessionEvent method (if so - which method should I use?)?
Thank you in advance for any help
Jan Kostrhun

Hello Jan,
For effeciency reasons the deleted objects are only placed in the UnitOfWorkChangeSet in the case of Cache Coordination (Cache Synchronization). If your application is not configured to use Cache Coordination the deleted objects can be found in unitOfWork.getObjectsDeletedDuringCommit(). Please note that this is an internal method in TopLink that may change in future released.
Accessing the UnitOfWorkChangeSet after you have called commit is fine.

What are aggregate objects ?

Hi,
Can anybody please tell me what are aggregate objects?
Regards,
Anirban.

Views matchcode and lockobjects are called aggregate objects since they are formed using several tables
Aggregate objects
Views , matchcodes and lock objects are called aggregate objects since they are formed using several related objects
Views: A view is an imaginary table. It contains data, which is really stored in other tables. The contents for the view are dynamically generated when called from program.
Lock objects: These types of objects are used for locking the access to database records in table. This mechanism is used to enforce data integrity that is two users cannot update the same data at the same time. With lock objects you can lock table-field or whole table.
Match codes :
Tool that helps us to search data records in the system.

Issues in persisting dynamic entity and view objects using MDS

Hi Frank,
I m trying to save entity and view object xml by calling writeXMLContents() and saveXMLContents() so that these objects can be retrieved using the xmls later on.
These methods internally use MDS configuration in adf-config.xml, which is creating the issue.
Please share your thoughts on resolving this or if, there is any other way of creating dynamic entity/view objects for db tables created at runtime.

BI-IP and Business Objects?

Please refer to the thread:
BI-IP and Business Objects?

Ian,
reading through the messages, there seem to be a few questions that are raised. After attending SAP Financials 2008, here is what I got from it:
1. IP vs BPC: IP is still in production and will be developed (no commitment on time though. I was told somewhere between 18-24 months before it goes to maintenance mode). There is some functionality difference from BPC and right now these are two separate products. There is a talk of a possible integration in the "distant" future
2. BPC is in process of being developed for BI, but currently it is only running on top of Microsoft SQL server. The BI version is slated to be released June 28th, but majority of the experts are fairly pessimistic about that date.
Now, the main question is what will happen to IP when BEx and BO tools converge into one - based on my understanding, we are going to see ADDITIONAL functionality. Since all the WAD and Excel activities are based on BEx API's, it is highly unlikely that they are going to be dismissed in the new product. The process in which we assign functions/commands to the planning model might change, but I think only for the best

Difference b/w DATA TYPE and DATA OBJECT & differences b/w TYPE and LIKE

hai
can any one say the differences between Data type and Data Object.
And also differences between TYPE and LIKE
thanks
Gani

hi,
_Data Types and Data Objects_
      Programs work with local program data that is, with byte sequences in the working memory. Byte sequences that belong together are called fields and are characterized by a length, an identity (name), and as a further attribute by a data type. All programming languages have a concept that describes how the contents of a field are interpreted according to the data type.
      In the ABAP type concept, fields are called data objects. Each data object is thus an instance of an abstract data type. There are separate name spaces for data objects and data types. This means that a name can be the name of a data object as well as the name of a data type simultaneously.
Data Types
   As well as occurring as attributes of a data object, data types can also be defined independently. You can then use them later on in conjunction with a data object. The definition of a user-defined data type is based on a set of predefined elementary data types. You can define data types either locally in the declaration part of a program using the TYPESstatement) or globally in the ABAP Dictionary. You can use your own data types to declare data objects or to check the types of parameters in generic operations.
     All programming languages distinguish between various types of data with various uses, such as .. type data for storing or displaying values and numerical data for calculations. The attributes in question are described using data types. You can define, for example, how data is stored in the repository, and how the ABAP statements work with the data.
Data types can be divided into elementary, reference, and complex types.
a. Elementary Types
These are data types of fixed or variable length that are not made up of other types.
The difference between variable length data types and fixed length data types is that the length and the memory space required by data objects of variable length data types can change dynamically during runtime, and that these data types cannot be defined irreversibly while the data object is being declared.
Predefined and User-Defined Elementary Data Types
You can also define your own elementary data types in ABAP using the TYPES statement. You base these on the predefined data types. This determines all of the technical attributes of the new data type. For example, you could define a data type P_2 with two decimal places, based on the predefined data type P. You could then use this new type in your data declarations.
b. Reference Types
Reference types are deep data types that describe reference variables, that is, data objects that contain references. A reference variable can be defined as a component of a complex data object such as a structure or internal table as well as a single field.
c. Complex Data Types
Complex data types are made up of other data types. A distinction is made here between structured types and table types.
Data Objects
      Data objects are the physical units with which ABAP statements work at runtime. The contents of a data object occupy memory space in the program. ABAP statements access these contents by addressing the name of the data object and interpret them according to the data type.. For example, statements can write the contents of data objects in lists or in the database, they can pass them to and receive them from routines, they can change them by assigning new values, and they can compare them in logical expressions.
       Each ABAP data object has a set of technical attributes, which are fully defined at all times when an ABAP program is running (field length, number of decimal places, and data type). You declare data objects either statically in the declaration part of an ABAP program (the most important statement for this is DATA), or dynamically at runtime (for example, when you call procedures). As well as fields in the memory area of the program, the program also treats literals like data objects.
        A data object is a part of the repository whose content can be addressed and interpreted by the program. All data objects must be declared in the ABAP program and are not persistent, meaning that they only exist while the program is being executed. Before you can process persistent data (such as data from a database table or from a sequential file), you must read it into data objects first. Conversely, if you want to retain the contents of a data object beyond the end of the program, you must save it in a persistent form.
Declaring Data Objects
      Apart from the interface parameters of procedures, you declare all of the data objects in an ABAP program or procedure in its declaration part. These declarative statements establish the data type of the object, along with any missing technical attributes. This takes place before the program is actually executed. The technical attributes can then be queried while the program is running.
     The interface parameters of procedures are generated as local data objects, but only when the procedure is actually called. You can define the technical attributes of the interface parameters in the procedure itself. If you do not, they adopt the attributes of the parameters from which they receive their values.
ABAP contains the following kinds of data objects:
a. Literals
Literals are not created by declarative statements. Instead, they exist in the program source code. Like all data objects, they have fixed technical attributes (field length, number of decimal places, data type), but no name. They are therefore referred to as unnamed data objects.
b. Named Data Objects
Data objects that have a name that you can use to address the ABAP program are known as named objects. These can be objects of various types, including text symbols, variables and constants.
Text symbols are pointers to texts in the text pool of the ABAP program. When the program starts, the corresponding data objects are generated from the texts stored in the text pool. They can be addressed using the name of the text symbol.
Variables are data objects whose contents can be changed using ABAP statements. You declare variables using the DATA, CLASS-DATA, STATICS, PARAMETERS, SELECT-OPTIONS, and RANGESstatements.
Constants are data objects whose contents cannot be changed. You declare constants using the CONSTANTSstatement.
c. Anonymous Data Objects
Data objects that cannot be addressed using a name are known as anonymous data objects. They are created using the CREATE DATAstatement and can be addressed using reference variables.
d. System-Defined Data Objects
System-defined data objects do not have to be declared explicitly - they are always available at runtime.
e. Interface Work Areas
Interface work areas are special variables that serve as interfaces between programs, screens, and logical databases. You declare interface work areas using the TABLES and NODESstatements.
What is the difference between Type and Like?
Answer1:
TYPE, you assign datatype directly to the data object while declaring.
LIKE,you assign the datatype of another object to the declaring data object. The datatype is referenced indirectly.
Answer2:
Type is a keyword used to refer to a data type whereas Like is a keyword used to copy the existing properties of already existing data object.
Answer3:
type refers the existing data type
like refers the existing data object
reward if useful

Newbie question about entity and view objects

Hi everyone,
My first ADF application in JDeveloper is off to a difficult start. Having come from a forms background, I know that it is necessary avoid using post-query type lookups in order to have full filtering using F11/Ctrl+F11. This means creating an CRUDable view and getting as much of the lookup data as possible into the view without losing the ability to modify the data. In JDeveloper, I do not know how to build my data model to support that. My thought was to start with a robust updateable view as my main CRUD EO and then create a VO on top of that with additional EOs or VOs. But, I have found that I cannot add VOs to another VO. However, if I link the VOs then I have a master-detail which will not work for me.
For example, I have two joins to CSI_INST_EXTEND_ATTRIB_V shown in the queries below and need to have that show in the table displaying the CRUD VO’s data. It seemed that the best way to do this is to create a CSI_INST_EXTEND_ATTRIB_V entity object and view object. The view object would have two parameters, P_INSTANCE_ID and P_ATTRIBUTE name. Both the building and the unit are needed on the same record, and this is not a master-detail even though it might look that way. (A master-detail data control will not work for me because I need all this data to appear on the same line in the table.) So, I need help figuring out the best way to link these to the main (CRUD) view; I want as much of this data as possible to be filterable.
select
cieav.attribute_value
from
csi_inst_extend_attrib_v cieav
where cieav.instance_id = p_instance_id
and cieav.attribute_code = 'BUILDING NAME'
select
cieav.attribute_value
from
csi_inst_extend_attrib_v cieav
where cieav.instance_id = p_instance_id
and cieav.attribute_code = 'UNIT NAME'
Ultimately, I need to display a ton of data in each record displayed in the UI table, so a ton of joins will be needed. And, I need to be able to add records using the UI table also.
James

Hi Alejandro,
Sorry if I caused confusion with my first post. What I had in mind assumed that I could have a single CSI_INST_EXTEND_ATTRIB_V EO with a BuildingVO and UnitVO on top of it. So, I wrote the queries individually to show how I would invoke each view. When I realized that confused the issue, I rewrote the query to explain things better.
Now having seen your 2 queries. You need to create 2 EO. One for each table. Then create an association between the 2 aeO (this will be the join you are talking about). Then, you need to create a VO based on one of the EO and after you can modify and add the second EO (in here you select the join type).
After your done with this, youll have 1 VO that supports CRUD in both tables.
There were three tables in the query: CIEAV_BUILDING, CIEAV_UNIT, and T -- the main CRUD table. When you say that I should create two EOs, do you mean that they are to be for CIEAV_BUILDING and CIEAV_UNIT? Or, CIEAV and T? Assuming CIEAV and T, that sounds like it would allow me to show my building or unit on the record but not both.
By the way, everything is a reference except for the main CRUD table.
Look forward to hearing from you. Thanks for your help (and patience).

Beginners Guide sound installation -- OSS and ALSA objective features

Beginners Guide sound installation -- OSS and ALSA objective features needed
Hi,
In most wiki pages i just edit the things that i think need editing. Just look at the oss history
In all those cases i didn't really saw a need to ask for permission.. that would kinda destroy the wiki idea.
However i want to change the sound instructions in the beginners guide so i made a copy of the entire guide and the part that i changed there is: http://wiki.archlinux.org/index.php/Use … ling_Sound now i have a slight issue there. As you can see i'm in favor of OSS and because you can spot that it's not objective. Now i would ask 2 things.
1. Could you all post your features of OSS and ALSA
2. Once that's done can i have permission to place that section in the beginners guide? that will also include removing the sound installation from the beginners guide which i already did in my version
My personal reason to do this. i've read this and am since then pro OSS and against the ALSA/PulseAudio combo. i think that combo needs to get out of linux (most notably Fedora and Ubuntu) ASAP. and oss needs to go back into the linux kernel
Thank you for your time,
Mark

I'm an alsa/pulse user, so I'll give a bit of the 'other side'.
Alsa/pulse
Pros:-
network sound
advanced connection of sink/source (including merging sinks)
bluetooth support!
highly supported by existing apps, either through directly supporting Pulse or through its alsa plugin (you should not need to recompile properly-written apps which do not assume they should write audio data directly to hardware, I think I only needed to recompile mpd on my system)
Cons:-
Setup isn't the easiest. Can't comment vs OSS4 because I haven't tried it
OSS4
Pros:-
Everyone seems to say sound quality is better. I guess that's because they're comparing it with dmix alsa. Use pulse with alsa and you should not notice any difference in sound quality though.
Cons:-
Most apps nowadays default output to alsa. Meaning OSS plays them using an alsa plugin.
USB support is admittedly skimpy.
EDIT: Having read the sound article you referred to, my only comment is that the writer really has it in for Pulse... 3 seconds latency, where'd he get that from? I use pulse for audio recording (when I'm lazy to fire up JACK) and while there IS latency, its definitely in the ms range.
Thanx for the input

markg85, libflashsupport isn't needed. [1]

If you don't know, please don't put in wiki, this could cause unnecessary problems. As for the mms section:
If your stream sounds ugly in totem like it did with me then you could try to play it with another codec like ffmpeg (mplayer). That "fixed" the issue for me. This will not fix the issue that somehow pops up in gstreamer when playing MMS streams but it will give you the option to play it with good sound quality. Playing it in mplayer is simple:
# mplayer mmsh://yourstreamurl
Could you fix this? ffmpeg is not a codec . Also define ugly, and what is somehow?
markg85 wrote:Thanx a lot for your feedback. i will certainly use it when i make more edits.
As for the things you didn't know. As soon as i fully understand how i can get a microphone working in OSS i will add that to the wiki as well. Unless you already know it.. in that case, feel free to add it.
For the mic, I did get mine going. Can't remember just how I did mine (sorry, think I had to disable one of the inputs), but do remember to prevent it from passing through the speakers had to disable "Misc Microphone".

For libflashsupport on the same page you linked it clearly states:
# Flash V9 and V10 require libflashsupport to output sound via OSS. Typically a 32-bit version of the library is required.
# Flash V10 has a 64-bit version which requires a 64 bit libflashsupport.
Also i tested it with and without libflashsupport. On archlinux (x64 running here) there most certainly is a need for libflashsupport when you want to have sound in your flash. And yes i tested the archlinux OSS version and the mercurial version (running now) bith need it installed manually! On my pc sound in flash didn't work without it but did with it. So, no not removing from the wiki as it's needed. But i see you removed it for me! please do NOT do that if you didn't even verified it. I use flash 10 x64 and i need it!
As for the ffmpeg "codec" changed it to backend.
And i did get the microphone working near perfect: http://www.4front-tech.com/forum/viewtopic.php?p=13192
Now for some news you all might like.
On my school i need to do an investigation to whatever i want and i'm heavily thinking about investigating the pros/cons of alsa compared to oss (or oss compared to alsa). That investigation will take from monday next week till next mondey till friday 23 of oktober. In that investigation i'm going to do some in depth look of alsa and oss and that will include the usability as well.
Following up on that investigation i will spend another 8 weeks on my school making a volume control application that can be used with alsa and oss and easily expandable with other sound systems. The goal of this is to make one sound application that can manage (in the first place) alsa and oss. oss is going to be implemented and alsa is probably going to be dummy implemented because it's likely way to much for me to implement both.
Before you get to exited, both projects (investigating and making the application) are just made up today and i just don't know if both will get accepted by my school. I asked one teacher and he liked the idea a lot and could potentially have a value for the sound management under linux. Once i do get this started i will involve the community (YOU!) with this since this project can't be done without the community specially the investigation.
And once i start and have something to tell/ask i will blog about it on http://blog.mageprojects.com

And this idea already got dumped. read more a few posts down or click: http://bbs.archlinux.org/viewtopic.php? … 34#p612634

How to find out the PATTERN, GRADIENT and BRUSHED objects?

How to find out the PATTERN, GRADIENT and BRUSHED objects information in illustrator active document file. And also how to find the CMYK and RGB color information in illustrator file through javascript. Could you please provide any examples.

I tried using the below code. But for both "cmyk" and "grayscale" pattern it gives only CMYK. Kindly check and advise.
Code:
var docRef = activeDocument;
for(var i=docRef.inkList.length-1;i>=0;i--){
var inkRef=docRef.inkList[i];
var inkRefName=inkRef.name;
alert(inkRefName);
alert(inkRef.inkInfo.kind);
Thanks for looking into this.

How to find all those list of SAP standard and custom objects that are changed from a specific point of time

Hi all,
Please let me know the process to track or find all the SAP Standard and custom objects. that got changed from a specific point of time.
Is there any function module or any table where this change log is maintained.?
I just only need the details ,wheather that SAP standard or Custom object has got changed or not.
Thanks in advance

Hi RK v ,
I really don't know what your actual requirement is , but if you want to know the objects as per the modification , then transport request will be much help to you .
Have a look into table E070 and E071 .
