ORA-12528: TNS listener BLOCKED - trying to duplicate database

Dude!Dec 18 2010 — edited Mar 26 2012
Hello,

I would like to test the RMAN duplicate from active database in version 11.2.0.1.

The name of the duplicate (auxiliary) database should be "clonedb". I created a password file, spfile and added the clonedb database to tnsnames.ora. The clonedb instance is in nomount state. Tnsping clonedb is also working.

When I try to make a connection:
sqlplus 'sys/mypassword@clonedb as sysdba'
ORA-12528, Blocked, all appropriate instances are blocking new connections.

So I wonder if this could be due to the nomount state of the instance and dynamic listener configuration. Correct?

I made an entry in the listener.ora file, and it's showing "clonedb" status UKNOWN now, but I still cannot make a sqlnet connection since the dynamic listener apparently takes precedence. Can I turn off the dynamic listener configuration, but then I will loose the connection to the other databases. Do I need to make manual entries in listener.ora for all databases in order to perform RMAN duplicate?

I also tried to connect to the auxiliary clonedb instance as local target with OS authentication, but the ORA-12528 error persists. Sqlplus / as sysdba works though. Below some more info. Any ideas how to resolve the issue.

Thanks!
