Check that you are able to connect to database using tnsnames.ora entries

tnsping TIGGER_DGMRL

sqlplus sys@TIGGER as sysdba

Standby Site:

Add an oratab entry to make sure you have a SID to set the environment variables.

--Please Note: Execute the duplicate from active database command from the Standby site to pull the files over the network.

--Create the adump directory first before running the rman duplicate command. If you don't the rman command will fail.
mkdir /u01/app/oracle/admin/tigger_stby/adump

Force the startup of a “Dummy” instance

rman target /

--*****************************************************************************************************************
-- 8.  Create standby redo logs on the primary and standby database that are the same size of the online redo logs. 
--*****************************************************************************************************************

Oracle recommends having the same number plus one additional standby redo log for each thread. 

For example: Minimum of (threads)*(groups Per Threads + 1) 

(3)*(2 + 1) = 9 Redo Logs

You can check the number and group numbers of the redo logs by querying the V$LOG view:
SQL> SELECT * FROM V$LOG;
You can check the results of the previous statements by querying the V$STANDBY_LOG view:
SQL> SELECT * FROM V$STANDBY_LOG;
You can also see the members created by querying the V$LOGFILE view:
SQL> SELECT * FROM V$LOGFILE;

SQL> select max (bytes)/1024/1024, count (1) from v$log;


    GROUP# BYTES/1024/1024

         1             250
