ORA-01033: Recovering database

Question

Hi,
I have 2 database running on my local system ( Windows-XP, Oracle 10g ).
After abrupt shutdown of the system, one of my DB is throwing an error ORA-01033 ORACLE initialization or shutdown in progress.
So I tried with below given things to fix the error.
c:\sqlplus /nolog
SQL> connect sys as sysdba
SQL> shutdown
SQL> startup
It gave an error..
ORA-12528:TNS:Listener:All Appropriate instances are blocking new connections
SQL> select status from v$instance;
ORA-03114: not connected to ORACLE
So I tried stopping and restarting the Listener.
LSNRCTL> stop
LSNRCTL> start
Then again tried to startup the database
SQL> startup
ORA-01041: internal error. hostdef extension doesn't exist
SQL> alter database mount;
SQL> alter database open;
Alertlog file shows....

O/S-Error: (OS 23) Data error (cyclic redundancy check).
It looks like block corruption in the sysaux tablespace file.
Please help me, in recovering the database. ( in detail / steps is very much appreciated )

Answer 1

It would be important to know what kind of backups do you have.
Do you have offline backup?
Do you have archive mode turned on?
