Switchover using DGMGRL breaks off with ORA-03113: end-of-file on communication channel

Hi,

I created a Data Guard 11.2.0.4.0 environment consisting of 1 primary and 1 standby. I configured the Data Guard Broker, performed the preliminary tests described in Oracle Data Guard Concepts and Administration and Oracle Data Guard Broker, and manually tested all listener connections between the 2 instances. Parameter local_listener has been set, standby listener shows the DGMGRL and DGB services.

The DGMGRL switchover seems to be unable to set up a connection using service D2540P_SZ1309_DGB.p. However I'm able to connect to the standby instance with SQL*Plus using this service and also when using the connect descriptor as shown in the alert log.

Howdy, Stranger!
