How to Configure a Parallel Environment

Complete the follow procedures to configure a parallel environment:

1. Review the parallel environment key management options to determine how to implement single sign–on.
2. Create the r12.0 SP3 environment.
3. Do one of the following:
   • Be sure that both environments meet the common key store single sign–on requirements.
   • Be sure that both environments meet the multiple key store single sign–on requirements.
4. (Optional) Migrate the r12.x policy store data.
5. Review the user directory single sign–on requirements.

Parallel Environment Key Management Options

Managing SiteMinder keys to maintain single sign–on between the existing environment and r12.0 SP3 environment is critical to a successful parallel upgrade. Two SiteMinder key management options are available. The option you deploy depends on how you implement one or more key stores across both environments. The options include:

• Multiple policy stores with a common key store
• Multiple policy stores with separate key stores
