I have RAC DB and I wasn't able to start it up, below is the error:

SQL> startup
ORA-01078: failure in processing system parameters
ORA-00828: specified value of shared_pool_reserved_size inconsistent with internal settings
SQL>



Obviously, there is a wrong value for shared_pool_reserved_size and I need to somehow get the value so I can change it to the right value. I wasn't able to oen, neither mount the DB so I can't get the information and correct it.

How can I fix this issue?

thx.
