Cause: The value of the DB_BLOCK_SIZE initialization parameter used to start
this database does not match the value used when that database was created.
Potential reasons for this mismatch are:
1. mounting the wrong database
2. using the wrong initialization parameter file
3. the value of the DB_BLOCK_SIZE parameter was changed
Action: For one of the above causes, either:
1. mount the correct database
2. use the correct initialization parameter file
3. correct the value of the DB_BLOCK_SIZE parameter
