ORA-00058: DB_BLOCK_SIZE must be string to mount this database (not string)


ORA-00058: DB_BLOCK_SIZE must be string to mount this database (not string)
Cause: DB_BLOCK_SIZE initialization parameter is wrong for the database being mounted. It does not match the value used to create the database.
Action: Fix the value of the DB_BLOCK_SIZE parameter or mount a database that matches the value.


Example:


SQL> startup
ORACLE instance started.

Total System Global Area  520093696 bytes
Fixed Size                  2031352 bytes
Variable Size             176161032 bytes
Database Buffers          339738624 bytes
Redo Buffers                2162688 bytes
ORA-00058: DB_BLOCK_SIZE must be 16384 to mount this database (not 8192)


SQL> shutdown immediate
ORA-01507: database not mounted


ORACLE instance shut down.
SQL> exit
