How to Create a Technical Disaster

A Technical Disaster Recovery Implementation plan is a plan of the actual implementation of the hardware and software at the disaster recovery location. This plan ensures there are no unforeseen surprises when building the disaster recovery solution and that all critical systems and their components have been accounted for. This paper focuses mainly on Oracle centric applications in Unix/Linux environment. The Technical Disaster Recovery Implementation plan includes: • Creating a technical register of applications and servers. • Creating application consistency groups (different applications must work together consistently to guarantee integrity in the data). • Define a server mapping (either one-to-one or many-to-one). Will each primary server have its own disaster recovery server, or will several primary servers be consolidated to one disaster recovery server? • Creating a configuration register for each primary server including OS, patches, firewall rules, etc. • Software licenses and media considerations. • Synchronisation methodology. • Oracle standby database implementation. • Best practise primary servers. • Best practice standby servers.
