Presentation Title

Minimizing Downtime of Planned Outages with Oracle Goldengate

Abstract

System outages cause the worst type of performance. That is, it offers no performance. Planned downtime can be just as disruptive to operations as unplanned downtime. This is especially true for the increasing number environments expecting availability 24 hours a day, 7 days a week.

Traditionally planned downtime was required for the following activities:

  • Period Maintenance — such as patching or upgrades to the database, operating system, hardware or application
  • New deployments — major upgrades or new rollout of hardware, database, operating system or application

In this session, Stephan will present two examples of using Oracle GoldenGate to achieve minimal service interruption when;

  1. Upgrading/Migrating the database
  2. Applying a major application upgrade

By following the approaches outlined in this presentation and using the configuration best practices, it should be possible to reduce the downtime requirement of upgrades and migrations to near zero.
