I'd like to set up NA for Disaster Recovery. I have the following environment:
NA1 - NA 10.40 Linux RHEL 7.5 VM - Standalone install of NA.
Primary DB Server running Oracle 12.c with "na" instance in Dataguard ( to Remote DB server in DR location )
DR Location ( about 200 miles away):
NA2 NA 10.40 Linux RHEL 7.5 VM - Standalone install of NA.
DB Server running Oracle 12.c with "na" instance in Dataguard replication
I have read the post:
The setup I"m interested in is, as Chris Powers said:
In a nutshell, DR works as this:
NA1 Core & DB at location 1 are active - Currently have this
NA2 Core & DB at location 2 are inactive / down - DB replication is happening in background. - WANT TO HAVE THIS , only have DB replication part.
Say location 1 has an issue, you bring Core 1 and DB 1 down, bring Core 2 and DB 2 up. So, you'd need some DB help (or scripting / automation). The NA side of things - it's really easy to do as long as you have server / proxy access.
Even if you had two cores up, you'd have some work to do if say Core 1 dies as you'd want to make sure that Core2 knows Core 1 isn't able to participate.
I've checked the online documents but it's not clear what I need to do for the NA side of things. Could someone tell me the details to complete the setup for NA1 and NA2 ?
