Generic query generating a list of date time. You need to substitute required interval number.

I am sharing a nice article on RTF template design written by one of our senior consultant Mr. Venkat from Adiva Consulting.

The objective of this post is to explain the “sorting” capabilities available in the RTF. Many might
already be aware of the standard BI Publisher syntax for sorting in the RTF template:

The above construct sorts the data by the VENDOR_NAME in ascending order – an alphabetic sort
is performed. However, what if the requirement was to sort on a number field.

Summary: An index created on column that has many duplicated rows can be tuned to save space as well as I/O trips by compressing the index defined on it.

Details: By default when we create index in Oracle, the compression is disabled on it. What if we have an index defined on a column that contains last name of all the customers, some of the names are very common as a last name. We can take advantage of this duplicated data by compressing the index defined on it.

The Problem
===========
The longer you've been working as a DBA, the more you've encountered things like these:

The time on a table changed and you don't remember doing it. You poke around but can't figure out who changed it.

There's someone you don't trust that you have to give access to. They are the kind of person that will look at things they are not supposed to, but you have to give them access.

There's someone who always messes things up when they get access. You know they'll do it again and you'll have to undo the damage. Would be nice to know what they are doing.

There's a contractor or a new employee that need access. You don't know them yet and not sure how reliable they are. It would be nice to be able to keep an eye on them.

Too many people have too much access and you're losing control. You try to figure out how to reduce the access they have or revoke some privileges, but this is pretty much what everyone claims they need to do their jobs.

You've been through an audit and the auditor wanted to know all sorts of things about the activity. Questions you just don't have the information needed to answer.

You probably spent many days chasing down the answers to these questions or try to find ways to collect it. The security in the database is set properly. The problem is that you need to know what people are doing with the access they have. This knowledge will give you more control.

Performance Improvement in Pro*C

Pro*C code compilation builds executable depends on the parameters passed while compiling a code on Linux OS. GCC compiler is widely used for compilation.

Parameters that it provides enables memory management and linking etc...
This means : Without changing Code GCC compilation parameter change can give significant improvement in performance without impacting functionality. Attached document contents details study of the same.

This document gives details about environment,deployment and pre-post change analysis.

If you moved to BI Publisher 11g or OBIEE 11g from BI Publisher 10g, you would have realized that debug option is no longer part of BI Publisher Administration UI. In 10g we can set the debug log level from Administration UI under Server configuration section but in 11g no more.In OBIEE 11g, it is central logging process which is part of Fusion Middleware.

Yesterday I am importing some table data in non production database using Datapump utility.
