Business continuity plans are necessary within any organization. The planning, preparation, and testing that goes into a business continuity plan is critical to ensure that your company data is not sacrificed should an event occur that renders your systems unavailable.
Disaster recovery is one part of a company's Business Continuity Plan. DR is certainly a critical piece of any EBS install to protect financial, manufacturing, HR/Payroll, etc. data. Unfortunately, DR is often neglected, not tested, and assumed to be in working order should a dire event occur. It is Tier1's practice to implement, monitor daily, and test annually a client's DR procedures. This is the only practice that will ensure restore and recovery of your EBS and data when the unexpected happens.
There are many decisions that need to be considered when developing a DR plan
What type of DR event are you planning for: server loss, site loss, or regional loss?
How much data can you sustain to lose?
How long can your systems be unavailable?
Is it acceptable for performance of the Production E-Business Suite to be impacted by a DR solution?
The best DR plan for your company depends on your requirements for the questions listed above. Protecting against regional loss of your systems also protects against server and site loss. However, it may not be a feasible approach if you cannot withstand any downtime of your systems. Likewise, if your company cannot accept any data loss, a regional plan may also not be feasible as the bandwidth requirements may be too great to sustain an acceptable level of performance with the E-Business Suite.
Once you have defined your requirements for DR, you can use a combination of the solutions below to begin building your DR plan for the E-Business Suite database and application tiers:
Tier1 has implemented many different combinations of the above technologies to satisfy our customer's business continuity and disaster recovery objectives. Many customers choose Data Guard, Oracle's premier replication technology, to satisfy their DR requirements. Data Guard is configurable and allows the customer to strike an appropriate balance between uptime, data protection, and application performance. However, Data Guard requires appropriate licensing from Oracle and some customers do not have the luxury of paying the additional licensing fees to implement Data Guard. Therefore, with Tier1's assistance, guidance, and experience, these customers can choose one, or a combination, of the above options to meet their Business Continuity and Disaster Recovery objectives.
