Dataguard and the data guard broker

in High Availability Data Guard, Sharding and Global Data Services (MOSC) 6 commentsAnswered ✓

I am running oracle 19.11 enterprise edition on OS RedHat7

I am testing data guard: I have a target database and its standby - all running pretty well for over a month now. I have tested switch over and back without any issues.

I have started working with the dataguard broker. It is adding a very thick layer of complexity to the database management:

I have to enable fast_start failover and a use flashback database besides the additional restrictions once fast start failover is enabled.

My question is do I have to use the broker? What are the advantages and disadvantages of this?

Howdy, Stranger!
