My current client has the crew here doing a good deal of data pivoting in migrating data between several Oracle Systems. I figured to turn some heads in a code review by providing a solution for data pivots which is not based on "locally favored" traditional 3GL coding practices but instead employs what is to me the more natural way of doing it for an Oracle database. I was right, heads did turn. Since I now have to document it, I figured why not post it on OraFAQ once and then tell them its online, come here and read it. So this is an example of pivoting in SQL.

This article describes the process of upgrading the Oracle Database Server 10g Release 10.1.0.2 to Oracle Database 10g Release 10.1.0.5 on Windows XP SP2.

Oracle-Bashing

Aside from a nine month excursion to Sybase IQ, I've spent my entire career working with Oracle, so I don't profess too much expertise - indeed any! - about other RDBMS technologies. So in a weak attempt at self-education, I recently accepted an invitation to listen to a Teradata presentation directed at application developers.

My newest project needed to create a record keeping component that would keep track of balancing results over time. Sounded good, meant my customers could look back over time to see how things went, and it provided persistent evidence of good results. I figured on adding two routines (save/get) to a logging package already in existence to save balancing data via an autonomous transaction and retrieve it when needed. But in writing these routines it dawned on me that they would destroy the reusable nature of the logging package. Finally, a real life use for ANYDATA.

Most of the Oracle 10g databases are using ASM for storage as it's very simple to maintain the storage w.r.t. to Disks, Datafiles etc.

Introduction

Oracle 10g’s brilliant alternative to database point in time recovery is the the Flashback Database feature. With this feature in place you can do almost everything that you can with point in time recovery, without actually having to go through all the disruptions and hassle that a PITR necessarily entails.I recently had a first hand opportunity to see the power of this feature, when I ran a scriptfile to drop tables and unwittingly dropped one of the tables containing sensitive information belonging to my employer Creative Infotech. I later recovered the table and was amazed at seeing how easy it had become to get back dropped objects in Oracle 10g, especially Release 2. Below is a simplified version of what I did

Advanced features of Oracle Net include failover and load balancing. These features are actually interrelated in as much as you usually don’t have one without the other. While they are mostly used in a RAC environment, they can be set up in a single instance environment as well.

FAILOVER:
In the context of Oracle Net, failover refers to the mechanism of switching over to an alternate resource when connection to the primary resource gets terminated due to any reason. Connection failure may be broadly categorized as:

“Find out how to use DBMS_SQLTUNE package to tune SQL Statements in Oracle 10g”

Have you ever been frustrated with SQL Tuning?
Did you get lost in the maze of /+ HINTS +/ and analysis paralysis?
Pre-10g you have to be either a SQL tuning expert or should have a license to expensive tuning tools available in the market to effectively tune SQL Statements. Not the case anymore.

In 10g you can use DBMS_SQLTUNE package to get tuning recommendations for SQL Statements.

Overview

Tuning of SQL Statements using DBMS_SQLTUNE involves following 4 steps:

Every PL/SQl devloper must have tried their hands with dynamic SQl. Its an indelible part of oracle.But its generally used when we dont know at compile time about the object on which we are to perform the task. Suppose we want to insert data into a table but we get the name of the table during the execution of the procedure, in those cases we would use dynamic SQl with the table name passed as bind variable. Dynamic Sql is even used to execute DDl commands inside a PL/SQl block.
