Hi everybody, I've configured a couple of primary/standby (physical) databases on two separated hosts, 10.1.0.5, RHEL ES3.I've read DG Concepts and Administration manual, but I'm a little confused about some parameters:Q1. DB_UNIQUE_NAME: is it mandatory to have them different when DG is on separated hosts?
Absolutely- they must be , db_unique_name is the way the 2 (more if you have additional standbys) instances communicate with *each other*
Q2. INSTANCE_NAME: the same as Q1 + can be omitted?
Absolutely - you dont need it at all. this is just another parameter that gets in the way. Forget about instance_name
