or

SQL>alter database recover managed standby database cancel;
SQL> alter database recover managed standby database using current logfile disconnect;

How to avoid this issue

1. This Problem occurs if Managed Recovery is started manually which should not be done at all if there is an active Data Guard Broker Configuration.

Typically the Data Guard Broker should start Managed Recovery .

2. It can also happen if there are no Standby Redo Logs in Place or they are incorrect configured - reference Usage, Benefits and Limitations of Standby Redo Logs (SRL) Doc ID 219344.1
