Dataguard configuration on EBS 12.1.3 with 11.2.0.3

Hi,

our current architecture is we have 2 nodes one for database and the other for application. Currently i am implementing dataguard by following the MOS 1070033.1 i have some confusion regardin the Section 4: Creating a Physical Standby Database 4.6 Modify the database init.ora parameters on the standby server. In this section

$ cd <ORACLE_HOME>/dbs

$ cp <CONTEXT_NAME>_ifile.ora <STNDBY_CONTEXT>_ifile.ora

Update the following parameters:

DB_UNIQUE_NAME to a name different from primary: for example dg12s

LOG_ARCHIVE_DEST_2 to point to the standby service. This is required when standby is switched to primary and ships redo to new standby
