ORA-10458: standby database requires recovery

For some reason when I was trying to start me DR instance I was getting the error that need recovery for the database. Something like this:

oracle@testdb01 (db1tesd) bin]$ srvctl start database -d db1tesd
PRCR-1079 : Failed to start resource ora.db1tesd.db
CRS-5017: The resource action "ora.db1tesd.db start" encountered the following error:
ORA-10458: standby database requires recovery
ORA-01196: file 1 is inconsistent due to a failed media recovery session
ORA-01110: data file 1: '+DATA/db1tesd/datafile/system.284.881230789'
. For details refer to "(:CLSN00107:)" in "/u01/app/11.2.0/grid/log/testdb01/agent/ohasd/oraagent_grid//oraagent_grid.log".
CRS-2674: Start of 'ora.db1tesd.db' on 'testdb01' failed
[oracle@testdb01 (db1tesd) bin]$ 

In order to fix the issue what I did was started standby in nomount

• mount as standby
• open database in read only
• recovery managed standby database using current logfile 

Actual steps:

SQL> startup nomount
ORA-32004: obsolete or deprecated parameter(s) specified for RDBMS instance
ORACLE instance started.

Or make sure that log shipping process is enabled on primary in DGMGRL by issuing below on primary

alter system set log_archive_dest_state_2=enable scope=both sid='*';

below on DR:

ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE DISCONNECT;
