12cR1 RAC Posts -- 8f : Accessing data in the PDB in the Standby

Apparently, the error :
< br />
alter pluggable database pdb open
*
ERROR at line 1:
ORA-44309: unknown failure
ORA-44777: Pluggable database service cannot be started.

in my previous post was a spurious error.

I am able to access the PDB in the Standby.  Thus :

[oracle@oem132 ~]$ . oraenv
ORACLE_SID = [STBY] ? STBY
The Oracle base remains unchanged with value /u01/app/oracle
[oracle@oem132 ~]$ sqlplus '/ as sysdba'

Thus, the PDB on the Standby *does* OPEN READ ONLY and I can see the data that had been populated from the Primary.
