ORA-12528: TNS:listener: all appropriate instances are blocking new connections.

ORA-12528: TNS:listener: all appropriate instances are blocking new connections.

Cause :  This condition may be temporary, such as at instance startup. In my case instance are in nomount mode and I am trying to connect database through Primary database.

Solution : After adding SID_LIST_LISTENER in listener I have solved this problem.
