Top Destroyer #1
Ad Hoc & Period Ending reports run
against a Production DB with some
ODBC based BI or Reporting Tool
Use a Reporting Database instead
Use OpenEdge Replication to create a
D/R, Reporting DB Copy on another

Look @ BravePoint’s Pro2SQL Product
Regularly run UPDATE STATISTICS

Top Destroyer #5
Not using After Imaging
Although that’s more of a Database or
job future destroyer than a
performance destroyer

Top Destroyer #6
Not performing a Regular Dump & Load
Using Type 2 Storage Areas does NOT
mean you’ll never need to D&L again –

Top Destroyer #9
Monitor Java (or the processes that
use Java)
WebSpeed Broker

Top Enhancer #1
Shared R-Code Libraries (also known
as Memory Mapped Libraries)
Conserve Memory because code is
shared rather than in each Client’s
private memory
Code execution is much faster

Top Enhancer #2
Stripe (RAID 0) Database Disks
Not required for the AI or BI Disks
JBOD is sooo 90’s
