PL/SQL EO design issue - OAF

Hi everyone,
A PL/SQL EO should create per business function unlike the Java EOs where we create one EO per database object. Every Java/PLSQL EO should be mapped to some entity. As PLSQL EO is not specific to particular entity (may involves DML operation on more than one table ), i found that we have to associate through some DUMMY table.
But in my case PL/SQL code is acting on entities base and TL tables ( i mean on one view - VL entity )
So i made xxxVLEO as PL/SQL EO. But my PL/SQL code needs some other attributes other than entity attributes. So i added some transient attributes to xxxVLEO and made use of that.
So now there is common xxxVLEO for both PLSQL operations and entity search operations.
Is the way i'm doing is correct???
Can we create PL/SQL EO over view???
Can u please suggest me if anything wrong.
Thanks,
Praveen Kumar

SQL Server 2014 issues

Hello:
I have bumped upon a design issue with SQL Server 2014.
I want to report this to Microsoft, where it can be addressed and corrected in the upcoming Service packs.
This is something critical.. (that's what at least....I feel).
Please let me know the link/Forum where I can post this.
Thanks

Two possibilities. On Microsoft connect
https://connect.microsoft.com/SQLServer/Feedback
or in SQL Server forums.

Design issue with the multiprovider

Design issue with the multiprovider :
I have the following problem when using my multiprovider.
The data flow is like this. I have the info-objects IobjectA, IobjectB, IobjectCin my Cube.(Source for this data is s-systemA)
And from another s-system I am also loading the masterdata for IobjectA
Now I have created the multiprovider based on the cube and IobjectA.
However, surprisingly join in not workign in multiprovider correctly.
Scenario :
Record from the Cube.
IObjectA= 1AAA
IObjectB = 2BBB
IObjectC = 3CCC
Records from IobjectA =1AAA.
I expect the record should be like this :
IObjectA : IObjectB: IObjectC
1AAA       :2BBB       :3CCC
However, I am getting the record like this:
IObjectA : IObjectB: IObjectC
1AAA       :2BBB       :3CCC
1AAA         : #             :#
In the Identification section I have selected both the entries for IobjectA still I am getting this error.
My BW Version is 3.0B and the SP is 31.
Thanks in advance for your suggestion.

May be I was not clear enough in my first explanation, Let me try again to explain my scenario:
My Expectation from Multi Provider is :
IObjectA
1AAA
(From InfoObject)
Union
IObjectA     IObjectB     IObjectC
1AAA     2BBB     3CCC
(From Cube)
The record in the multiprovider should be :
IObjectA     IObjectB     IObjectC
1AAA     2BBB     3CCC
Because, this is what the Union says .. and the Definition of the multiprovider also says the same thing :
http://help.sap.com/saphelp_bw30b/helpdata/EN/ad/6b023b6069d22ee10000000a11402f/frameset.htm
Do you still think this is how the behaviour of the multiprovider.. if that is the case what would be the purpose of having an infoobject in the multiprovider.
Thank you very much in advance for your responses.
Best Regards.,
Praveen.

Data mart from two DSOs to one - Loosing values - Design issue

Dear BW experts,
I´m dealing with a design issue for which I would really appreciate any help and suggestions.
I will be as briefly as possible, and explain further based on the doubts , questions I received in order to make it easier go through this problem.
I have two standard DSOs (DSO #1 and #2) feeding a third DSO (DSO #3), also standard.
Each transformation DOES NOT include all fields, but only some of them.
One of the source DSO (let´s call it DSO #1) is uploaded with a datasource that allows reverse type of records (Record Mode = 'R'). Therefore some updates on DSO #1 comes with one entry with record mode 'R' and a 2nd entry with record mode = 'N' (new).
Both feeds are delta mode, and not the same entries are updated through each of them, but the entries that are updated can differ (means an specific entry (unique key values) could be update by one of the feeds, but no updates on the 2nd feed for that entry).
Issue we have: When a 'R' and 'N' entries happen in DSO #1 for any entry, that entry is also reversed and re created in the target DSO #3 (even being that not ALL fields are mapped in the transformation), and thefore we loose ALL the values that are exclusively updated through DSO #2, becoming blank.
I don´t know it we are missing something in our design, or how should we fix this issue we have.
Hope I was more or less clear with the description.
´d really appreciatted your feedback.
Thanks!!
Gustavo

Hi Gustavo
Two things I need to know.
1. Do you have any End Routine in your DSO? If yes, what is the setting under "Update behavior of End Routine Display"....Option available right side of Delete Button ater End Rouine.
2. Did you try with Full Load from DSO1 and DSO2 to DSO3? Do you face the same problem?

Design issue with sharing LV2 style global between run-time executables

Hi,
Just when I though that I had everything figured out, I ran into this design issue.
The application that I wrote is pretty much a client-server application where the server publishes data and the client subscribes data using data sockets. Once the client gets all the data in the mainClient.vi program, I use LV2 style (using shift registers) to make the data global to all the other sub-vi’s. So the LV2 is in initialize mode in the mainClient.vi program and then in the sub-vi’s the LV2 is in read mode. Also, I had built the run time menu for each sub-vi that when an item is selected from the menu, I would use the get menu selection to get the item tag which will be the file nam
e of the sub-vi and open the selected sub-vi using vi server. This all worked great on my workstation where I have labVIEW 7.0 Express installed. But the final goal is to make exe’s for each of these sub-vi’s and install runtime on the PC’s that do not have labVIEW installed. Of course when I did that only the mainClient.exe program was getting the updated data from the server but the sub-vi’s were not getting the data from the mainClient.exe. I did realize that the reason for this is due to the fact that I had compiled all the sub-vi’s separately and so the LV2 vi is now local to each executable (i.e. all executables have their own memory location). Also, the run-time menu did not work because now I am trying to open an executable using vi server properties.
To summarize, is there a way to share LV2 style global's between executables without compiling all of the sub-vi’s at one time? I tried using data-sockets (local-host) instead of LV2 st
yle gloabls to communicate between the sub-vi’s but I ran into performance issues due to the large volume of data.
I would really appreciate it if anyone can suggest a solution/alternative to this problem.
Thanks
Nish

If the LV2 global is loaded statically into your mainClient.vi, then any
other application can connect to the exe and get a reference to the VI
using the VI name. This gives you a VI reference you can use to call
the VI. Ye
s, the values will be copied between applications. That is
why you need to add access operations to the global that returns just
the info needed. If you need the average, do that in the global. If
you need the array size, do that in the global. Returning the entire
array shouldn't be a common operation on the LV2 style global anyway.

Your app does need to watch both the amount of data being passed across
the network, and the amount being shared between the apps. You might
want to consider puttin
g the VIs back into the main app. What is the
reason you are breaking them apart for?

A web service design issue with patterns

Hello,
I�d like to ask for your help in the following design issue:
I need to create an email sending web service (with Axis). Only just one method which returns with an integer return code. This handles the following:
- based on the given parameters gets the email addresses from an
LDAP server (with netscape ldap for java)
-     makes a cache from them (only after a timeout period will be the cache
refreshed) (don�t know what tool to use for this)
-     selects html templates which to be sent based on the given parameters
-     sends emails with the appropriate templates (with Velocity)
-     the whole process is logged (with log4j)
I have to write the code as generic as possible. I know that some design pattern should be used for this. (some from GoF , and I know there exists design patterns specially created for web services as well).
Could you enumerate me which patterns (and for what part of the program) would be the best choice to solve this problem? I have read through some books about patterns, but don�t have the knowledge to pick up the right one for a concrete problem like this..
Thank you in advance,
nagybaly

Hello,

I would also advise that you not embed all this in a servlet. Make a service that collaborates with several objects to accomplish the task and let the serlvet just call it.
.> - based on the given parameters gets the email

Stop thinking patterns and start thinking objects.

How to connect to SQL*Plus and issue a query all in one command?

Hi everyone,
Does anyone know of a way to connect to a db with SQL*Plus, and issue a simple query, all with one command?
I know that I can save a .sql script with a query, then do this:
sqlplus user/pwd@db @myscript.sql
But I'm wondering if there's any way to put the actual query right into the connect command, something like:
sqlplus user/pwd@db "select count(*) from dba_tables;"
Does anyone know of a way to do this?

you didn't mention windows or unix. so, here's a link with both

SOA Design issues and other politics

Hi all,
I have a requirement for live data feed from external system. I am using SOA11g and JDeveloper 11g. There are two designs, one proposed and other I have in mind to achieve this.
1) The external system sends XML data in a push model to the exposed SOA Web Service (uses one-way messaging mode) at my end. I then store the message in the database
a) In this design how do we keep track of all messages that are sent are received. Is there a better solution.
2) The third party is proposing a Web Service at their end. The application being real-time (i.e any changes at their DB end i.e some DB tables, should be propogated across to our web services using XML messages). I will have to keep sending XML requests on a regular basis (say every 5 seconds). Can I achieve such type of Web Service client using SOA 11g?
a) Here I have a design issue, that the data feed is live, why do the WS client have to keep sending requests at regular intervals. Why can't the third party send data whenever there is an update/insert at their database end. Third party is coming up with advantages like loose coupling and making the Web Service more generic. I doubt all the claims give that the applications are B2B and we are the other ones who will be using their web services for the time being. Their may be other two organizations later on.
b) If the first request is not yet returned, will the second request after 5 seconds be blocked.
This designs and solutions are becoming quite political across organizations, and got to do with who will take the blame for data issues. I just want a proper SOA design for live data feed. Please suggest the advantages and disadvantages of both if anybody has been through this path.
Thanks

Design Issue: Localization using Lookup OR Dependency Injection

Hello Forums!
I'm having a design issue regarding localization in my application. I'm using Spring Framework (www.springframework.org) as an
application container, which provides DI (dependency injection) - but the issue is not Spring- but rather design related. All localization
logic is encapsulated in a separate class ("I18nManager"), which basically is just a wrapper around multiple Java ResourceBundles.
Right now localization is performed in the "traditional" look-up style, e.g.
ApplicationContext.getMessage("some.message.key");
where ApplicationContext is a wrapper around the Spring application context and getMessage(...) is a static method on that
context. The advantage of that solution is a clean & simple interface design, localization merely becomes a feature of classes, but
is not part of their public API. The only problem with that approach is the very tight coupling of Classes to the ApplicationContext, which
really is a problem when you want to use code outside of an application context. The importance of this problem increases if one considers
that I18N is a concern that can be found in every application layer, from GUI to business to data tier, all those components suddenly depdend
on an application context being present.
My proposed solution to this problem is a "Localizable" interface, which may provide mutators for an "I18NManager" instance that can be
passed in. But is this really a well-designed solution, as almost any object in an application may be required to implement this interface?
I'm too concerned about performance: the look-up solution does not need to pass references to localizable objects, whereas my proposed solution
will require 1 I18NManager reference per localizable object, which might cause troubles if you let's say load 10.000 POJOs from some database that
are all localizable.
So (finally) my question: how do you handle such design issues? Are there any other solutions out there that I'm not aware of yet? Comments/Help welcome!

I'm having a design issue regarding localization in my application. I'm using Spring Framework (www.springframework.org) as an
application container, which provides DI (dependency injection) - but the issue is not Spring- but rather design related. All localization
logic is encapsulated in a separate class ("I18nManager"), which basically is just a wrapper around multiple Java ResourceBundles.Why do you think you need a wrapper around resource bundles? Spring does very well with I18N, as well as Java does. What improvement do you think you bring?
Right now localization is performed in the "traditional" look-up style, e.g.
ApplicationContext.getMessage("some.message.key");
where ApplicationContext is a wrapper around the Spring application context and getMessage(...) is a static method on that
context. Now you're wrapping the Spring app context? Oh, brother. Sounds mad to me.
The advantage of that solution is a clean & simple interface design, localization merely becomes a feature of classes, but
is not part of their public API. The only problem with that approach is the very tight coupling of Classes to the ApplicationContext, which
really is a problem when you want to use code outside of an application context. The importance of this problem increases if one considers
that I18N is a concern that can be found in every application layer, from GUI to business to data tier, all those components suddenly depdend
on an application context being present.One man's "tight coupling" is another person's dependency.
I agree that overly tight coupling can be a problem, but sometimes a dependency just can't be helped. They aren't all bad. The only class with no dependencies calls no one and is called by no one. We'd call that a big, fat main class. What good is that?
Personally, I would discourage you from wrapping Spring too much. I doubt that you're improving your life. Better to use Spring straight, the way it was intended. I find that they're much better designers than I am.
My proposed solution to this problem is a "Localizable" interface, which may provide mutators for an "I18NManager" instance that can be
passed in. But is this really a well-designed solution, as almost any object in an application may be required to implement this interface?I would say no.
I'm too concerned about performance: the look-up solution does not need to pass references to localizable objects, whereas my proposed solution
will require 1 I18NManager reference per localizable object, which might cause troubles if you let's say load 10.000 POJOs from some database that
are all localizable.
So (finally) my question: how do you handle such design issues? Are there any other solutions out there that I'm not aware of yet? Comments/Help welcome!I would use the features that are built into Spring and Java until I ran into a problem. It seems to me that you're wrapping your way into a problem and making things more complex than they need to be.

Design Issues, suggestions welcome

I have stumbled across some design issues, with a carhire system i am making.
          kept in
     [CAR]------------------->[GARAGE]

                    |
                    | Retives car from garage

                    [TIMESLOT]
As it stands the GARAGE class automatically has CAR objects added as attributes.
import java.util.*;
public class Garage {
     //class attributes
          private LinkedList carhold;
          Car ford_ka = new Car("A",135);
          Car ford_focus = new Car("B",149);
          Car ford_Mondeo = new Car("C",179);
           Car Vauxhall_Vectra = new Car("D",239);
          Car Mercedes_E240 = new Car("H",290);
          Car Renault_Espace = new Car("V",399);
     public Garage() {
          carhold = new LinkedList();
          carhold.add(ford_ka);
          carhold.add(ford_focus);
          carhold.add(ford_Mondeo);
          carhold.add(Vauxhall_Vectra);
          carhold.add(Mercedes_E240);
          carhold.add(Renault_Espace);          The TIMESLOT class has an GARAGE object as an attribute, thus enabling it access mehtods.
import java.util.*;
public class TimeSlot {
       Garage g = new Garage();
public void getCarCost(String input) {
           Car theCar = g.search(input);problem is each time a new TIMESLOT is create so too is a
new garage created with all the cars.
I really need the garage to be a seperate entity, but still allowing
the TIMESLOT class to use its methods.
would in heritence be the appropriate solution, or maybe something else.
I would like to hear other suggestions.

I believe a Singleton pattern works perfectly here. A singleton ensures that only one instance of an object is created. You would use it as follows:
public class Garage {
    private LinkedList carhold;
    // Car declarations here
    private Garage() {
        carhold = new LinkedList();
        // add cars here
    public static Garage getInstance() {
        static Garage instance = null;
        if (instance == null)
            instance = new Garage();
        return instance;
public class TimeSlot {
    public void getCarCost(String input) {
        Garage g = Garage.getInstance();
        // do some other stuff
}Notice the PRIVATE constructor on the Garage class. This keeps classes other than Garage from instantiating it. In fact, the only way to get an instance of Garage is to call Garage.getInstance(), which will always return the same instance.
You might also consider the Builder pattern, which will keep you from having to instantiate all those Car objects inside of your Garage. You would do something like this:
public class Garage {
    LinkedList carhold;
    public Garage() {
        carhold = new LinkedList();
    public void addCar(Car c) {
        carhold.add(c);
public class GarageBuilder {
    public static final int BOBS_GARAGE = 0;
    public static final int BILLS_GARAGE = 1;
    public static Garage buildGarage(int garage) {
        Garage g = new Garage();
        switch (garage) {
            case BOBS_GARAGE:
                Car c = new Car("bobsCar", 200);
                g.add(c);
                break;
            case BILLS_GARAGE:
                Car c = new Car("billsCar", 400);
                g.add(c);
                break;
        return g;
}

New sessions every time an sql statement is issued

Hi, I have a problem with using oraoledb (v 10.1.0) with VB6 accessing an Oracle database 9i (v 9.2.0.6). Every time an sql statement is issued in the client side, a new session is started in the server side (seen in Enterprise Manager). I don´'t know why. Is an oraoledb parameter or a database parameter? How can I avoid this? The big problem behind this behaviour is controling row locking. If I issue a "select field from table where conditions for update nowait(or wait n)", this creates a lock that belongs to a session. If a few sentences after I issue an "update the-same-table set the-same-field = value where the-same-condition" as this one creates a new session, an ORA-00054 is raised telling the row(s) is blocked.
any idea?
thanks

I'm a DBA and I encountered the same problem with a system developed for our company. We reported that to the company that developed the application and they sey then close the conections, but they remain in the database.
Could anyone find a solution for this? I believe is a problem in the VB code, but I do not know anything from VB.
thanks,
Lisandro

Required info on SQL Server Performance Issue Analysis and Troubleshoot way

Dear All,
I am going to prepare the simple documentation steps on SQL Server Performance Issue Analysis and troubleshoot method. I am struggling to make this documentation since we have different checklist (like network latency,disk latency, memory/processor pressure,SQL
query tuning etc) to validate once application performance issue reported from the customer.So, I am looking for the experts document or link sharing .
Your input will help for document preparation in better way.
Thanks in advance.
