今天在本机创建一个9i的数据库
操作系统：windows xp pro sp2
数据库 ：oracle 9.2.0.1.0
在创建过程中出现ORA-01503 ORA-00058错误，提示DB_BLOCK_SIZE不正确。
google之：
ORA-00058 DB_BLOCK_SIZE must be string to mount this database (not string)
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:
mounting the wrong database
using the wrong initialization parameter file
the value of the DB_BLOCK_SIZE parameter was changed
Action: For one of the above causes, either:
mount the correct database
use the correct initialization parameter file
correct the value of the DB_BLOCK_SIZE parameter
根据提示修改DB_BLOCK_SIZE，问题解决。
