I've already checked following information.
http://docs.delphix.com/display/DOCS42/Supported+Operating+Systems+and+DBMS+Versions+for+Oracle+Envi... The source and target must be running the same DBMS/Operating System combination (for example, Oracle 10.2.0.4 on RHEL 5.2) in order to successfully provision a VDB to the target.
If the DBMS versions are compatible, the OS version on a target host can be different from the OS version on the source host.

When we apply a patch of oracle database to source environment, do we have to apply same pach to target environment?
Oracle has various types of patches that we would like to know what we should do each patches.
Q1) Apply a PSR to source environment
e.g.
Source = 11.2.0.4
Target = 11.2.0.3
Q2) Apply a PSU to source environment
e.g.
Source = 11.2.0.4.2
Target = 11.2.0.4.1
Q3) Apply a CPU to source environment
e.g.
Source = 11.2.0.4 + CPU January 2015
Target = 11.2.0.4
Q4) Apply a individual patch to source environment
e.g.
Source = 11.2.0.4 + Patch X
Target = 11.2.0.4
