How to Send Archivelogs From Primary to Another Primary

Symptom:

   We need to send archive logs from an Oracle Primary open read-write Database to a remote another Primary  open read-write Database which is working as Goldengate log miner  or other purpose

Solution:

    We need to  set 2 init parameters

• log_archive_config   

ie  log_archive_config='dg_config=(primary,dr,newprimary,newdr......)'

We need to include all related db_unique_name in this parameter.
This is parameter controls who I can send and allow to receive archive logs

•  log_archive_dest_n 

ie log_archive_dest_2 ="service="TEST_DR", ASYNC NOAFFIRM delay=0 optional compression=disable max_failure=0 max_connections=1 reopen=300 db_unique_name="TEST_DR" net_timeout=30, valid_for=(online_logfile,all_roles)
