Dataguard replication

[Roshan]

Hello Erman,

Kindly advise if it is possible to replicate from standby to another standby or should we replicate from primary to standby only?

I know golden gate can run extract from standby instead of primary

Replicating from standby to standby is called cascaded standby conf.
This is a matter of choice. If you've the required bandwidth, you can directly replicate from primary to multiple standby databases, or if you don't; then you can implement a cascaded conf. There may be other cases where you want to have a cascaded conf. It depends on the context..
And yes, GG can extract data from standby.  That is fetching necessary data from a DataGuard standby system. There is a good post about that,
