Data Guard : LPX-00106 Warning: attribute "obsv_recn" of element "FAST_START_FAILOVER" is undefined

Creating a Dataguard configuration.

As far as I can see the data guard itself is playing nice: archive logs generated on the primary side are shipped and applied to the standby database.

I'm almost ready. Last thing to enable is the FSFO (Fast Start Fail Over).

DGMGRL> show configuration verbose;

Configuration - aosb2_dg_config

Thusfar, google and support.oracle.com didn't supply usefull information.

Can someone on the list shed some light please.
