DBUPGDIAG script to check integrity of database before 11g upgrade

Posted by Arjun Raja on August 20, 2009

Script to check integrity of a 9i or 10g database before upgrade to 11g.

Run this script connected as sysdba in the 9i or 10g database.

NAME: DBUPGDIAG.SQL

This script can be downloaded from Oracle Metalink note 556610.1

— PURPOSE:
— This script is intended to provide a user friendly output to diagonise
— the status of the database before (or) after upgrade. The script will
— create a file called db_upg_diag__.log in your local
— working directory. This does not make any DDL / DML modifications.

— This script will work in both Windows and Unix platforms from database
— version 9.2 or higher.
