FAQ - What does an 'internal' database optimise do, and how often should I run a database optimize?

Troubleshooting


Problem

Customer would like to know what an 'internal' Controller application database optimize does, and how often they should run one.

Symptom

There are two types of database optimisations that can be done:

(1) 'Internal' database optimisation.

  • These are triggered/launches from 'inside' the Controller client interface (inside the Controller GUI)
  • To launch them, click "Maintain - Users - Single Mode" and then click "Maintain - Database - Optimize"

(2) 'External' database optimisation.
  • These are optimisation techniques that are triggered outside of the Controller GUI (typically by using third-party database utilities)
  • Examples are given inside separate IBM Technotes such as #1396973 & 1346962.
