hi:

I am having a problem when i try to start the database. The problem is as:

----------------------
SQL> startup
ORACLE instance started.

Total System Global Area 239075328 bytes
Fixed Size 788308 bytes
Variable Size 212596908 bytes
Database Buffers 25165824 bytes
Redo Buffers 524288 bytes
Database mounted.
ORA-16038: log 3 sequence# 2329 cannot be archived
ORA-00227: corrupt block detected in controlfile: (block , # blocks )
ORA-00312: online log 3 thread 1: 'E:\ORACLE\ORADATA\ORACLE1\REDO03.LOG'


---


do i need to drop the log files and create once again.. if yes how do i proceed? or what is the best way to get rid of this problem?

Note: db wasnot shutdown properly.

Thanks in adv
Paras.
