Rolling PSU patches - Instance Availability

[satish]

Dear Erman,

For RAC,Oracle has released rolling patches to minimize the downtime.

In EBS...Before applying any db patch,we have to bring down application.When application is not available,users cannot use the instance.Then how these rolling patches will benifit us

Thank you,
satish

Ref Oracle : When performing patching in Rolling mode, the ORACLE_HOME processes on a particular node are shut down, the patch is applied, then the node is brought back up again. This process is repeated for each node in the GI or RAC environment until all nodes are patched.

So, this means; if your EBS environment is configured for surviving from a node shutdown/crash, then you can get benefit of rolling patches.
