How to access two entity managers from two different servers?

Hello
My test programm is trying to access two glassfish application servers (gf 2.1). The code base of these servers is the same, the persistence layers are just accessing different databases -> one ist the staging/test system, the other the live server.
After setting the connection and obtaining the em via the class persistence i can not fetch the em from the other system.
          properties.setProperty("org.omg.CORBA.ORBInitialHost", "host1");
          properties.setProperty("org.omg.CORBA.ORBInitialPort", "port1");
                InitialContext ctx = new InitialContext(properties);
          entityManagerFactory1 = Persistence.createEntityManagerFactory("pu/refdata");
          entityManager1 = entityManagerFactory.createEntityManager();After that Persistence seems to have been bound to host1 forever, so i can not fetch a reference to the em of host2. There is another createEntityManagerFactory method accepting a map but i dont find any reference for the properties, maybe that would help - dont know.
Regardless of what i do, any further call to Persistence.createEntityManagerFactory returns the handle of entityManagerFactory1.
Regards

I want to use the EntityManagers bound to the DataSources provided by different app servers.
Below you find an example persistence.xml with three entries. 1 & 2 have the same jta data source, 3 is different.
My point is that Persistence binds the new factory in a wrong way if the jta data source String has already been resolved.
If a progamm sets connection properties for app server 1 and fetches an entityManagerFactory for pu/refdata_Live, then sets connection properties for app server 2 with pu/refdata_Test they get different factory instances bound to the same server, in this case app server 1.
If i know set the connection properties for app server 3 with pu/refdata3 Persistence sees that the jta data source "dbc/ref3" has not yet been resolved and tries to connect to the app server 3. Which it should have done for app server 2 too.
<persistence-unit name="pu/refdata_Live" transaction-type="JTA">
     <provider>oracle.toplink.essentials.PersistenceProvider</provider>
    <jta-data-source>jdbc/ref</jta-data-source>
    <properties>
      <property name="toplink.ddl-generation" value="none"/>
    </properties>
</persistence-unit>
    <persistence-unit name="pu/refdata_Test" transaction-type="JTA">
    <provider>oracle.toplink.essentials.PersistenceProvider</provider>
    <jta-data-source>jdbc/ref</jta-data-source>
    <properties>
      <property name="toplink.ddl-generation" value="none"/>
    </properties>
</persistence-unit>
    <persistence-unit name="pu/refdata3" transaction-type="JTA">
    <provider>oracle.toplink.essentials.PersistenceProvider</provider>
    <jta-data-source>jdbc/ref3</jta-data-source>
    <properties>
      <property name="toplink.ddl-generation" value="none"/>
    </properties>
</persistence-unit>

Moved to SAP Integration kit forum
Appears you are using SAP data sources.
And yes you can but the linked field types must match and be able to be converted into the WHERE portion of the SQL. Click on Database, Show SQL... and see if there is one. If not CR can't figure out how to so it brings all data client side and filters on the second pass.
Thank you

end

The first AAA server listed in your config will always be used unless/until it becomes unavailable. At that point the NAD would move down to the next AAA server defined on the list and use that one until it becomes unavailable and then move to third one, and so on.
If you want to use two AAA servers at the same time then you will need to put a load balancer in front of them. Then the virtual IP (vip) will be listed in the NADs vs the individual AAA servers' IPs.
I hope this helps!
Thank you for rating helpful posts!

Can we access two different Siebel BO in Same OPA Rule Base

Hi all,
can we access two different BO's from same rule base.
what i means is,can we pass siebel data to OPA Rule Base from two different BO's .
Thank you for your help in advance.

There are two approaches to do this and they both involve making some small changes on the Siebel side.
You can create an Integration Object which contains all the business components that you want to send to OPA if you are using an Integration Object mapping.
If you would prefer to use a Business Object mapping then you will have to create a new Business Object which combines the BCs of all the Business Objects that you want to send to OPA.
As you can see, although one approach involves Integration Objects and one involves Business Objects they both work by creating a single object which is an amalgamation of the information that you want to send to OPA.
Cheers

How to Maintain two different prices for same material in different qty?

Dear all,
How to maintain two different prices for same material in different batch quantities in purchase order(ie.,info record)?
(Vendor is supplying quantities in 2 different batches & also in different prices)
Expecting valuable reply.
Jeyakanthan

In a PO you can create 2 items, and each item can be maintained with a different price in the conditions.
In info record it is not possible to have different prices for the same period, except for scales.
so if you have a price of e.g. 2 USD for 1000 kg and 1,90 USD for 2000 kg then you can maintain this in scales, but you still have to have 2 items in the PO so that each one can individually find its price.
Alternative you can create contracts (as well with more than one item) to reflect the different prices and batches.

OOABAP-How to access the protected methos from a class

hi,
If inheritance is used properly, it provides a significantly better structure, as common components only
need to be stored once centrally (in the superclass) and are then automatically available to subclasses.
Subclasses also profit immediately from changes (although the changes can also render them invalid!).
Inheritance provides very strong links between the superclass and the subclass. The subclass must
possess detailed knowledge of the implementation of the superclass, particularly for redefinition, but also in
order to use inherited components.
Even if, technically, the superclass does not know its subclasses, the
subclass often makes additional requirements of the superclass, for example, because a subclass needs
certain protected components or because implementation details in the superclass need to be changed in
the subclass in order to redefine methods.
The basic reason is that the developer of a (super)class cannot
normally predict all the requirements that subclasses will later need to make of the superclass.
Inheritance provides an extension of the visibility concept: there are protected components. The visibility of
these components lies between that of the public components (visible to all users, all subclasses, and the class itself), and private (visible only to the class itself). Protected components are visible to and can be used by all subclasses and the class itself.
Subclasses cannot access the private components particularly attributes) of the superclass. Private
components are genuinely private. This is particularly important if a (super)class needs to make local
enhancements to handle errors: it can use private components to do this without knowing or invalidating
subclasses.
Create your class inse24 and inherit this CL_GUI_TEXTEDIT
class in yours. You can then access the protected methods.
Hope this is helpful, <REMOVED BY MODERATOR>

Somehow I got it to work, a whole lot easier than i thought, kind of scary how easy... but Im not exactly sure what of several things is how I got it. Scariest thing; watching my iBook I wouldn't know that I was accessing it from the MB. It's only me doing it, but still seems so easy.
If I have a WPA2 password protected wireless network do I have to worry that others can access it so easily? (not that I have anything interesting, it's just the general privacy paranoia)
