System trigger handling in physical standby DB (active data guard)

edited Dec 28, 2015 10:00AM in High Availability Data Guard, Sharding and Global Data Services (MOSC) 3 commentsAnswered

Hi,

Does anyone has experience for system trigger handling in physical standby database?

I have enabled ADG in a standby database and the DB failed to startup.

The _system_trig_enabled need to be set in standby DB to fix the issue.

In addition, the switch over by Data Guard Broker might fail if system trigger exists in read-only standby DB (Doc id 1323789.1).

My question are:

should it be recommended to disable all system trigger in read-only standby DB (there are some built-in trigger according to 244524.1)?

what would be the impact for a read-only standby DB

Thanks
