The document discusses improving the performance of the UATIMNG database for an iManage data warehouse application. The application currently takes over a minute to generate complex reports from the 200GB database, which is expected to grow 30% annually. The goals are to reduce average query execution time by 60% and optimize the database to improve response times to within 60-70 seconds. Various techniques will be used including implementing Oracle Flexible Architecture and reorganizing tables and indexes to remove fragmentation and row chaining.

Use Oracle Flexible Architecture setup on
UATIMNG database. Also re organize the table
and indexes for removing fragmentation and row
chaining.

Business Case: iManage is data warehouse application. The
application consists of complex reports access by 30 users
simultaneously. Reports are generating from 'uatimng' database.
Currently database size is 200Gb and expected to grow to 30% a
year.
Generation on complex reports on growing data, user has to wait
more than a minute. On growing business, database and
application requires to capable to generate report within a minute.
By doing this, it will improve the performance of application &
saves users effort time.
Problem Statement: Generation on complex reports on growing
data, user has to wait more than a minute. Database and
application requires to capable to generate report within a minute.
Goal: :To reduce average query execution time by 60% on
imanage database by 31-aug-2006.
