Rman Duplicate database from Active database



From 11g above, you can use rman to duplicate database from an active database instead of from a backup.
Two big disadvantages of the ACTIVE database duplication method are:
·         Negative performance impact on the source database. This impact applies to the whole duplication time.
·         High network traffic on the connection between the source and target databases.
Test envorinment:
Source
     SID: testprd
     host:192.168.96.3
Target
     SID: testrman
      host: 192.168.96.4
