We are in the process of configuring a disaster recovery system for four small Oracle instances. Our approach will be to install Oracle on the box, restore backups of the production databases for test purposes, and then shut down the copies instances and delete them. The box will not be used again until we either need it for a real recovery or we are required to test our recovery procedures again. Note that the Oracle software will remain installed on the box and we will be keeping it patched to the same level as the production system. My management's rationale is that, since we are not running instances on the disaster recovery box, we do not need a separate license for it. When we loose the production box we will transfer the license to the disaster recovery box. Would Oracle agree? If it matters, this is Oracle 8.1.7.4 on AIX 5.2.
