Hi Oracle geeks,
Last Friday, I’ve noticed a strange thing happening in my 220.127.116.11 Database: I’m able to create objects in a tablespace which is marked READ ONLY !!!
Don’t believe this??
I have just joined an in flight project and find the lead data modeler has created a name value pair data model.
The reason given was flexibility of data model considering some records can have as many as 900 attributes. The .Net application team seem to be loving it, as they can code everything with very few tables in mind.
I feel the model is difficult to query, difficult to load and difficult to syndicate and in all likelyhood will suffer from poor performance.
I just posted a complete integrated set of tools to manage, monitor and tune the Oracle database.
It is free, no registration or email is required. I will just appreciate any kind of feedback to make it better.
The package comprises the following topics:
This section allows you to view and maintain virtually all database objects, including partitioned tables and materialized views. It also includes a function to view inter-dependency between objects.
This section allows you manage users and security.
Matthew Morris (who makes many constructive and knowledgeable contributions to the forum) has written a series of study guides for the OCA/OCP exams. I asked him if I could have a copy of one to review. The result: it's very good. This is a copy of the review I put up on Amazon.
The other day, I was asked how to move a table from one schema to another. The answer, as we all know, is "you can't do that: you have to create a new table as a copy of the old one, or use export/import. It will take a long long time." Not true.

[=16]In 9i,we open the database with resetlogs just only once when we do the incomplete recover,but in the 10g, it can open the database with resetlogs more than once,the flowing test is show how to open the database with resetlogs many times.
I've been asked by the publishers to review "Oracle Database 11g Release 2: Performance Tuning Tips and Techniques" by Richard Niemiec of TUSC. Conclusion: it is good but not perfect. This is an extended version of the review I put up on Amazon.
The following business events are disabled as default by Oracle.
For any custom process those can be enabled by users. But only extract and postprocessing events will be called in document mode.
Custom code / package can be used as a subscription to the respective business event.
oracle.apps.xla.accounting.preaccounting - To identify the events, which will be processed by create accounting oracle.apps.xla.accounting.extract - To populate the transaction objects only for the events in xla_events_gt
Dependency Oracle schema is the place where all the Database objects get stored. This make a room for the entire set of objects under the Category of Data Storage ( Tables, Views) and Data Access (Stored Procedure ,Functions ,Packages and Triggers) .These Objects make a reference across all these objects to form the application.This is known as dependency.
Conventional Dependency Model If an Object B is being referrd from object A (ie Object A refers another Object B) , Object A is known as Dependant Object and Object B is Known as referenced Object.
