The prerequisites are given below:
1. Primary and standby databases must use same version of Oracle database and must have Oracle Enterprise Edition or Personal Edition. Either primary or standby or both can be RAC or non-RAC database.
2. You must use SPFILE so that the broker can persistently reconcile values between broker properties and any related initialization parameter values. If you have RAC database then keep the spfile in shared storage.
3. Setup DG_BROKER_CONFIG_FILEn initialization parameters to a location where you want to keep broker configuration file. If you are in RAC environment, then you must set up the DG_BROKER_CONFIG_FILEn initialization parameters for that database such that they point to the same shared files for all instances of that database.
