It sounds like the big foundation elements are in place, but you’re asking a question that only you and you company can answer. The first question when engineering a Backup & Recovery system is “How quickly do we NEED to be operational again?”. Of course, we all WANT our data & computing resources back RIGHT NOW, but do you *need* to?
Once you have your critical functions identified and MTTR need, you can develop scenarios and mitigation plans. You have to factor in the most likely need for recovery, to the worst case scenario, and tier the recovery times depending on what resources will be involved (Hardware, alt location, tapes, backups on disk). Then meet the needs with the budget you can get or the resources you already have.
Techtarget has some outstanding whitepapers on Disaster Recovery planning and strategy – It will take much in the way of creativity and teaming to accomplish what you’re looking for, but when (not if) it comes time to use it, it is well worth the effort.
As for the quarterly patches, anyone who works with the DoD in any capacity is extremely familiar with the Oracle CPU process. With no profit margins to gain (from avoiding IA), and extremely sensitive information to lose, the DoD spends the money to ensure a proactive Information Assurance posture.
When you know that Oracle CPUs are not only beneficial, but a mandated install, you develop a plan and the soft & hard infrastructure to mitigate downtime. Luckily, unlike the willy-nilly timing of Microsoft patches, Oracle makes planning testing and implementation of their patches EASY. They have schedules patch releases 2 years out, like clockwork.
Depending on your budget & tolerance for downtime, you can optimize your databases before applying the CPU to minimize downtime, or you can shuffle Oracle Homes on the same box, or Stream to a standby server, or a host of other options. Given the ease of exploiting many of the vulnerabilities patched, it seems well worth the time to plan for this activity and engineer it into your Data Management System.]]>
