• Question 2:

  Which statement is true when you perform out-of-place patching with Oracle Enterprise Manager?

  A. It is the recommended approach when your Oracle Home does not follow Oracle Flexible Architecture.
  B. It is the recommended approach when downtime is not a time constraint.
  C. All database are patched simultaneously.
  D. You are not able to retrieve the path recommendations because you are not connected to the network.
  E. Your original Oracle Home is available for recovery operations.
  E. Your original Oracle Home is available for recovery operations.

  ---

  explanation:

  Using this mechanism [out-of-place patching] means that the only downtime will take place when the Databases from the previous Home are switched to run from the new Home. If there is any issue with the Database patch, you can switch back to the previous unpatched Home since it is still available. So, patch rollback is a lot faster. Note: A new mechanism for patching has been provided in Oracle Enterprise Manager Cloud Control 12c, known as Out of Place Patching. This is now the recommended method and creates a new Oracle Home, which is then patched while the previous Home is still operational. All this is done using an out-of-box Deployment Procedure in Enterprise Manager.

  Note:

  / Compare the consolidation scenarios you create to determine which consolidation strategy best meets your requirements.

  Your objective is to:

  *

  Match source server resource requirements with destination servers best able to meet those requirements

  *

  Fit source server requirements with each destination server's available resources as tightly as possible, so you can get maximum usage of destination server capacity

  *

  Optionally balance the source server workload across all available destination servers Reference: Oracle Enterprise Manager Cloud Administration Guide , Using Consolidation Planner
