Hi all,

I have one primary database and one physical standby database on my data guard environment.

Now i want one more physical standby database in my data guard environment, meaning i wnat 2 physical standby. since this is a production environment, i need to take great care. However, downtime will be mandatory.

Please help how to proceed?

You do not need any downtime to add another standby database to the environment. All the steps are in the Data Guard Concepts and Admin guide, the easiest technique is to use RMAN.

Hi John,

I have already one production and one physical standby in one building. Now my concern is that i have another server with oracle installed at DR site which is situated in another building 30 km apart.

i am currently using RMAN to back n restore my database. But according to my understanding, i have to put entry in my spfile. i will go to my DR site to restore the backup. In the admin guide, it is mentioned for one primary n one physical standby not 2 physical standby.

Please i have to take great care. I have 2000 users connected live on this db.

Hi,

My problem is

1.what additional configurations i have to perform on my production server.

2.Both physical standby config should be identical with only the db_unique name different.

3.log_archive_config='dg_config=(pup2,pup2stdby)'
on this line i have to put entry for second standby

*.log_archive_dest_2='service="pup2stdby"','LGWR ASYNC NOAFFIRM delay=0 optional compression=disable max_failure=0 max_connections=1 reopen=300 db_unique_name="pup2stdby" net_timeout=30','valid_for=(all_logfiles,primary_role)'

HERE I HAVE TO PUT LOG_ARCHIVE_DEST_3

*.log_archive_dest_state_1='enable'
*.log_archive_dest_state_2='ENABLE'

4. what about FAL SERVER n FAL CLIENT

Thanks,

sailesh
