How to add a new object to Toplink session cache?

Toplink Experts,
I have a question on Toplink 9.0.4.5 (I know this is older version of Toplink but this is what we are using right now). Let me give you little context before I ask the question.
Toplink server session brokers client sessions (that are spawned by it) and gets changes made in client sessions into server session through transaction commits. Process involved in getting some thing into database using Toplink is: 1) Get client session 2) Register object to be written into database with Toplink's UnitOfWork (UOW). This registration creates two copies of the object registered (original object). Working clone for client application for modifications, backup clone for Toplink to compare the changes made to the working clone later 4) Make changes to the working clone 5) Complete the transaction (and so commit UOW). If transaction commits successfully, Toplink writes the changes from the working clone into database first and applies the same changes made to the working clone to the original object in Toplink server session cache next. Oracle recommends using UOW to write some thing into database. Using UOW involves a transaction and it writes changes into database first before the original object in Toplink server session cache is refreshed.
Now comes my question: Is there a way to add a brand new object (persistent object) into Toplink server session cache with out writing it first into database? I am OK if I need to use UOW and also to use transaction to make the change but I just want to be able to refresh the original object in the server session cache with out writing any thing into database. If there is a way to do this? What are the disadvantages in doing this way though? I have read Oracle's Toplink developer guide (10.1.3) and Javadocs from Oracle on UnitOfWork/Session etc all related interfaces and classes but I could not find a way. Please help!

There are a couple things wrong with the method you posted. The first being uow.registerObject() is going to cause the object to be treated as new if you are not using the TopLink cache.
There really is not any supported mechanism to do what you are looking to do. TopLink 11g has the hooks to replace the TopLink cache with a distributed cache (and the TopLink-Grid product uses these to use Coherence as the TopLink cache) but earlier versions did not have this.
If you are willing to work outside what would be officially supported and no component of the application is using the ServerSession cache (ie all queries refresh) then something like the following may work for you:
public void prepareObjectForSave(Object userEditedObject, Object gigaSpacesObject)
UnitOfWork unitOfWork = this.dbContext.getSession().acquireUnitOfWork();
Descriptor descriptor = this.dbContext.getSession().getDescriptor(gigaSpacesObject);
Object pkVector = descriptor.getObjectBuilder().extractPrimaryKeyFromObject(gigaSpacesObject, this.dbContext.getSession());
Object cloneOfMostRecentlyUpdatedObject = (Object)unitOfWork.cloneAndRegisterObject(gigaSpacesObject, new CacheKey(pKVector), descriptor);
unitOfWork.mergeCloneWithReferences(userEditedObject);
unitOfWork.commit();
}You will need to tweak the above code to have it match the APIs in your version of TopLink and you should test thoroughly.

I’m sorry for the issue that you are hitting now.
This itextsharp is third party control, for this issue, I recommended to consult the control provider directly, I think they can give more precise troubleshooting.

How to add a container object in a station globals

Hi,
How to add a container object in a station globals

Hi radlou,
This might be what you're looking for:
NewSubProperty Method
Syntax
PropertyObject.NewSubProperty ( lookupString, ValueType, asArray, typeNameParam, options)
Purpose
Creates a new subproperty with the name the lookupString parameter specifies.
Parameters
lookupString As String
[In] Pass the lookup string for the new subproperty to be created. If you pass a lookup string with multiple levels (such as "x.y.z"), this method creates all of the necessary intermediate container objects. Refer to lookup string for more information about the strings you can use.
ValueType As PropertyValueTypes
[In] Pass the type of value you want the new subproperty to store.
asArray As Boolean
[In] Pass True to make the new subproperty an array whose elements are of the type you specify in valueType.
typeNameParam As String
[In] Pass the name of an existing type if you want to create the new subproperty as an instance of a named type. Otherwise, pass an empty string. If you pass a type name, you must pass PropValType_NamedType for the ValueType parameter. Refer to NamedPropertyTypes for a list of built-in named types.
options As Long
[In] Pass 0 to specify the default behavior, or pass one or more PropertyOptions constants. Use the bitwise-OR operator to specify multiple options. You do not need to pass the InsertIfMissing option to create the new subproperty. Pass DoNothingIfExists if you want the method to not report an error if the subproperty already exists.

How to add a new created table to SVN repository

Hello,
I am using SQL Developer and Data Modeler both with SVN repository.
If I am adding a new object (fe procedure) in SQL Developer, I have a right mouse menu option to add the new object to SVN. This works fine. When adding a new object (fe table) in Data Modeler, there is no option to add this new object to SVN. Does anyone have an idea how to achieve this?
Data Modeler version 3.3.0.734
Joop

Hello Philip,
thanks for your answer, but the OLL wasn't very helpful.
I found an option to add the object: you can add the object using the pending changes. In the outgoing changes you will find the new object with the icon with + symbol. Here you can commit in SVN.

How can I write new objects to the existing file with already written objec

Hi,
I've got a problem in my app.
Namely, my app stores data as objects written to the files. Everything is OK, when I write some data (objects of a class defined by me) to the file (by using writeObject method from ObjectOutputStream) and then I'm reading it sequencially by the corresponding readObject method (from ObjectInputStream).
Problems start when I add new objects to the already existing file (to the end of this file). Then, when I'm trying to read newly written data, I get an exception:
java.io.StreamCorruptedException
at java.io.ObjectInputStream.readObject0(Unknown Source)
at java.io.ObjectInputStream.readObject(Unknown Source)
Is there any method to avoid corrupting the stream? Maybe it is a silly problem, but I really can't cope with it! How can I write new objects to the existing file with already written objects?
If anyone of you know something about this issue, please help!
Jai

Here is a piece of sample codes. You can save the bytes read from the object by invoking save(byte[] b), and load the last inserted object by invoking load.

SQL Server Distributed Partitioning Views how to add a new node online

We are using distributed partitioning views in SQL Server 2012 Enterprise Edition for scaling out our data across more than one servers. Now we faced to question how to add a new node (server) into the scale outed db servers system without sending the servers
down, so our users will be able to use them during the process as well.
For example we have 4 servers with scaled out data. When we add the new empty server, the CHECKINGs for the partitioning columns should be reorganized. But during the process the partitioning views are not working.
The High Availability, Always On or Failover Cluster approaches seem are not resolve the problems.
So my question is how to add new node online?
KH

Thank you Erland for the reply.
Yes, it's sounds as possible solution but has some not resolvable nuance in it. Let's say we copied some data from Node5 to new added Node6. Let's assume in Node5 we had data in Table1 with partitioning column's values 100,101,102,103,104,105,106. Now
we want to copy part of the rows with partitioning column's values 103,104,105,106 from Node5.Table1 into Node6.Table1. With this Node5 will contain less data and will work more quickly (less IO, less CPU usage etc), and the rest data will be contained on
Node6. But because of Node5 is already in use, the Node5.Table1 contains CHECK CONSTRAINT = ParttionColumn should be from 100 up to 106. This is check for Node5. The Distributed Partitioning Views are already using the CHECKs to identify what server should
be used to get data from.
Now when we copied part of the Node5.Table1 rows to Node6.Table1 the views are still using the 103-106 rows from Node5.Table1 because the CHECK points there. Then we include the newest Node6.Table1 in the distributed partitioning views. OK, but we should
set some CHECK on new Node6.Table1 which will be used by views. We can't set intersecting checking like Node5 has CHECK 100-106 and Node6 has CHECK 103-106. We also can't edit Node5 check and set it 100-102 untill the data will be removed in it. But this means
that the data will not be available during the execution.
So, any ideas ?

How to add a new character set encoding?

Hello,
can anybody please explain to me, how to add a new character set encoding to Mac OS Tiger?
I have two Mac laptops, a new one with Snow Leopard and an older one with Tiger, and on the old one i cannot use or enable anywhere the "Russian (DOS)" character set encoding, which i need to be able to use some old text files.
On the Snow Leopard, this encoding is present in the list of available encodings of TextWrangler, but not in TIger.
If i have understood correctly, this is not a problem of TextWrangler, and the same encodings are available systemwide.
So, the question is: how to add new encodings to Tiger (or to Mac OS in general)?
Thanks.

I think possibly that's in the Get Info window of Finder?
I don't think either that or the input menu have any effect on available encoding choices. Adding languages to system prefs/international/languages can do that, but once you have added Russian there, I don't know of any way to add an additional Russian encoding (there are quite a number of them).
