Loose coupling among objects within oracle schema

I am building an information service that manages Suppliers. The suppliers are used by our billing system, tender system and sales system. Though 60% of the attributes of supplier are unique to each system, there are still 40% attributes of Supplier that are shared across the systems.
My objective is to build a flexible system, so that change to one individual system's data, should not impact other systems. For example, if i need to make certain tables offline for upgrading them, it should not impact rest of the systems that need supplier information. What is the best way of achieving this? Should all the different context specific attributes live in one schema, but deployed on different table spaces? Also, the read and update may happen more for one set of attributes than the other. How should i logically represent them via one model, but deploy them in such a fashion that they can evolve independently?
Thank you.

Reports - All reports - Data dictionary reports - Database administration - All tables - All tables, and specify B as schema name.
Have fun,

XDK 9.2.0.2.0 XML Schema Validation within Oracle 8i database

I am little confused on this forum regarding my problem to find out the possibility of XML Schema Validation using SAX Parser within Oracle 8.1.7 database java stored procedures.
Right know I am trying to find out if it is possible to make XML Schema Validation using SAX parser within Oracle 8.1.7 java stored procedures using (loading) new Oracle 9i Rel 2 XDK jar files into database.

Attemp to build loosely coupled WS using xsd:any & xsd:anyType?

Dear All,
i want to write a loosely coupled web service that allow
the server to evolve independently to the client. (main
purpose is to extend the service by adding more properties
in the request / response message)
i want to achieve the loosely coupled goal by adding
xsd:any or xsd:anyType to the request / response messages
(i.e. wsdl ComplexType). (just follow the normal XML
guideline).
i have try to write simple program with xsd:any (which
mapped to SOAPElement in JAX-RPC). And the result seems
good and can achieve my goal. ( i can consume the service
in java and .net without problem).
but later, i read some article, in the web, (like this: http://www.ibm.com/developerworks/xml/library/ws-tip-xsdcaution.html)
that clams it is better to use xsd:anyType instead of
xsd:any (as anyType is mapped to SOAPElement or java
object if server/client can deserialize it).
as far as i know, the support of xsd:anyType is not standardized / madatory.
could anyone tell me your comment about using xsd:anyType or xsd:any?
how about the support of xsd:anyType across different platform / tools?
xsd:anyAttribute seems not supported by jax-rpc, could you please comment on using this element in the wsdl? good or bad?
oracle will map this element to an oracle proprietary java object.
am i choosing the right way to achieve loosely-coupled WS? any other way?
some article claims to send request as xml doc. but it
seems that is not very convenient to server and client as
both sides need to write code for serialization /
deserialization.
why not use the existing automatic XML <--> java object provided by the jax-rpc standard?
Thank you very much

Hello,
Is your question related to very specific element of your message or for the complete message.
Using any/anyType even if powerful could be sometimes complex for Web Service Client developer to handle since the Java object (SOAPElement or Object) is not typed so doing late binding of schema force people to do the mapping themself any.
So before choosing this in a wide scope on your project think also to its impact for end user/developers, and I think you are on the good path, as you said anyType will recognize the object.
I am inviting you to also look at the Oracle Web Services Interoperability documentation.
and this article from SUN: Interoperability With Patterns and Strategies for Document-Based Web Services

Scripts of objects in a schema.

Hi
I am working on a problem which is:
To generate the scripts of objects in a schema, with separate object types in different folders, with separate files for each object.
For instance if I have a schema called HR then the scripts for all the tables in this schema should be in a predefined folder called TABLES and within this folder the individual scripts for tables tab1.sql , tab2.sql.. and so on. I need to do this for all objects in the given schema. This I need to do from sql*plus and not from any GUI.
For this I am able to figure out some basic steps required. Below is the sample for same
DECLARE
V_SCRIPT VARCHAR2(4000);
CURSOR C1 IS
SELECT OBJECT_TYPE,OBJECT_NAME,OWNER
FROM ALL_OBJECTS WHERE OWNER ='HR' ;
BEGIN
FOR I IN C1 LOOP
      with scripts as (select dbms_metadata.get_ddl(I.OBJECT_TYPE,I.OBJECT_NAME,I.OWNER) txt from dual)
      select replace(txt,'"') ||'/' script_text INTO V_SCRIPT from scripts;
      DBMS_OUTPUT.PUT_LINE(V_SCRIPT);
END LOOP;
END;
{code}
Here in the script I can identify few problems like:
1. The DBMS_OUTPUT.PUT_LINE will work till the buffer level and after that will give an error message. Is there any way to eliminate this?
2. How can I spool the files in the middle of pl/sql code.
These scripts are to be created on a windows system in some location like *c:\scripts\tables\..*,*c:\scripts\indexes\..* and so on.
The database version should be:
{code}
Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - Prod
PL/SQL Release 10.2.0.3.0 - Production
"CORE     10.2.0.3.0     Production"
TNS for 32-bit Windows: Version 10.2.0.3.0 - Production
NLSRTL Version 10.2.0.3.0 - Production
{code}
Also I came to know of utl_file package, can I use this for the same.
please provide your expert guidance for the problem.
Thanks
Ansh

Two thoughts:
First: The Oracle database does not have folders. What product are you working in?
Second: Cursor loops such as the one you've written have been obsolete in Oracle for more than 12 years: Why are you writing one now?
Look up BULK COLLECT and FORALL at http://tahiti.oracle.com

Regarding Objects in Oracle

Hai all,
I want to know where could I get good material on using Objects in Oracle (in Forms) plus some good tutorial regarding the same.
Thanx
Vinayak

it it necessary to use adadmin to compile these objects and whether to use this with Maintenance Mode.No it is not necessary to use adadmin but recommended and you do not need to enable maintenance mode before compiling invalids irrespective of using adadmin or utlrp or adcomps.pls
I was previously using urlrp.sql/etc to recompile invalid objects with non-APPS environment, so what is the difference in these 2. here also you can use utlrp.sql but ideally we use utlrp.sql when no one is connected to system but adadmin can be used while users are in. Also through adadmin you can compile invalid of apps schema only and utlrp will compile all invalids in db.
adadmin calls $AD_TOP/sql/adcompsc.sql for compiling invalids. You can read this sql to view its functioning.
what could be the issues, if i run manual recompile on running APPS environment or by using Oracle EM to compile APPS/etc Scheama.You can do it manually, no issues.
Thanks,
JD

Cant view objects from another schemas

Hi everybody!
I have a 10.1.2 Jdeveloper and a 9.2.4 Oracle database.
I successfully created a database connection.
With provided login I can access to tables from another schemas in SQL Worksheet, but I cant see any objects from those schemas in the connection tree.
What's wrong?

The Schemas are being filtered so that you only automatically see the schema for the connection that you logged on with. To change the schemas that are visible you need to :
1) Select the connection name in the Navigator (you should see that it has a filter icon overlaid showing that it is being filtered)
2) Invoke the context menu and select 'Apply filters'
3) Shuttle over the other Schemas you wish to see and press OK

How to create loosely coupled transaction branches with DBMS_XA ?

Hello,
I use DBMS_XA to start several sessions in the same database instance participating a global transactions. The local transaction branches are tightly coupled.
Do you know a way (Oracle 11.2) for the branches to be loosely coupled by using dbms_xa in one-only instance ?

Loading Oracle Schema into XML Schema format

Hello,
I'd like to load the Oracle schema information (tables/views, columns, and constraints) into XML Schema format, then read in the XML Schema information to instantiate objects which will be used to build adhoc/dynamic queries. I have the dynamic query part working, but it was not clear to me how to convert the Oracle schema to XML Schema then XML Schema to custom objects. Does anyone have experience with this or ideas as to how to go about this?
Thanks,

Use the Oracle WebRowSet. The WebRowSet interface extends the RowSet interface and is the XML document representation of a RowSet object. A WebRowSet object represents a set of fetched database table rows, including the database metadata, which may be modified without being connected to the database.

Are WTC transactions loosely coupled?

Hello,
I am looking for a confirmation that XA transactions between Tuxedo and WLS (using WTC) are only loosely coupled.
I cannot find much details on how WTC handles transactions from and to Tuxedo.
On the Tuxedo side, it is stated clearly that transactions accross domains are loosely coupled. Since Tuxedo and WLS instances are in different domains, I am assuming that transactions between Tuxedo and WLS have the same constraints as Tuxedo inter-domain transactions. Unless WTC were to optimize such transactions.
The specific challenge we face is as follows (using Tuxedo 10.0, WLS 10.3, Oracle 11g):
1) A Tuxedo Corba App starts a transaction and does some work.
2) The Tuxedo Corba App calls an EJB service in WLS.
3) The EJB service does some work and updates a record in the Oracle DB.
4) The EJB service returns control to the Tuxedo Corba App.
5) The Tuxedo Corba App selects the same record that the EJB updated.
6) The Tuxedo Corba App does some more work, and the commits the transaction.
The problem is that in step (5) we don't see the update that the EJB made. If we replace the select in step (5) with an update, the update times out because the record is locked. However, the global transaction commits or rolls back correctly on both sides. This indicates that the transaction branches in Tuxedo and WLS are loosely coupled.
Roger

Across Tuxedo /Domain the transaction is loosely coupled. WTC is subjected to the same limitation. So you are correct, those XA transactions between Tuxedo and WLS are loosely coupled.

How to export objects of specific schema?

I need to export object of specific schema so please let me know how?
Thanks,
Waheed.

First thing you want to do - decide whether you will use the exp/imp or the expdp/impdp (data pump) routines.
To make THAT decision for 10g/11g look at CHapter 11 of the Concepts manual. (no decision in 9i - no data pump)
Once that decision is made, use the appropriate parameters as found in the Utilities manual - for every version from Oracle version 5 on. The parameters are different between exp and expdp

Sql script files to recreate SYS objects in Oracle 9i

Hello all.
I am working with a test Oracle database which is missing some SYS objects. (Oracle 9i).
I was wondering if Oracle has any scripts that I can run and recreate those?
Thank you,
Sonya

catalog.sql only creates the data dictionary views , not the underlying tables and indexes.
(sql.bsq is the "internal" script that is executed to create objects in the SYS schema when a CREATE DATABASE command is issued --- but Oracle will not support anyone attempting to use this script directly).

Pesky loose coupling question

Hey guys,
I have 3 files: main.mxml, registration.mxml, and
update.mxml. The registration is a custom canvas component with a
datagrid, and the update is a popup activated by clicking the
datagrid. I understand how to dispatch custom events, but I'm
having trouble dispatching from popup back to main.mxml where my
remote code is located. I can successfully dispatch objects with a
custom event from reg component to main. What am I doing wrong?
Should I just add a remote command in the registration component
and run a function in the registration? Doesn't seem like loose
coupling to me?

If your registration component is instantiated in main and
you dispatch an event that bubbles from registration to main, then
bubbling works. But forget about bubbling when dispatching an event
from a popup to any other component. You can do the following:
If you use a model (with Cairngorm, PureMVC ... or simply
Singleton), you can have an object in your model that extends
EventDispatcher and serves as a message target.
package com.mycompany.core.model
import flash.events.EventDispatcher;
// This class only serves as the target for messages that
concern objects that are not
// in the display list or that are in the display list but
cannot be reached by event bubbling
public class MessageTarget extends EventDispatcher
public function MessageTarget()
In your model:
// Message target
public var messageTarget:MessageTarget = new
MessageTarget();
In any component interested in some messages (e.g column
visibility) dispatched on the message target :
// Add event listener for column visibility change
this.model.messageTarget.addEventListener(ColumnVisibilityChangedEvent.COLUMN_VISIBILITY_ CHANGED,
this.onColumnVisibilityChanged);
Then, you can dispatch an event from anywhere that can be
listened to anywhere:
// Send Column Visibility Changed event
this.model.messageTarget.dispatchEvent(
new
ColumnVisibilityChangedEvent(ColumnVisibilityChangedEvent.COLUMN_VISIBILITY_CHANGED,
false, false));
