If getting an error

I tried flushing my shared_pool and then checked to see how large my shared_pool was:

SQL> alter system flush shared_pool;

System altered.

select dbms_rcvman.getpackageversion from dual

shared_pool_reserved_size big integer 10M
shared_pool_size big integer 200M

System altered.

SQL> select dbms_rcvman.getpackageversion from dual;
