PDB

=================

Customer has a 2 node RAC Container database.  He is trying to close a PDB on all the instances using following command:

alter pluggable database PDB1 close instances=ALL;

As per the documentation, it should close  PDB on all the instances,  but it only closing the PDB on local instance and not on remote instance.

CAUSE

Customer had parallel_force_local=true,  so a parallel slave was not spawned to close the remote PDB.

SOLUTION

alter system set parallel_force_local=false;
alter pluggable database PDB1 close immediate instances=all ;

SQL> show parameter local;

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
local_listener                       string       (ADDRESS=(PROTOCOL=TCP)(HOST=
                                                 192.168.52.183)(PORT=1521))
parallel_force_local                 boolean     FALSE
