Recently my machine got shut down because of some UPS failure, when I was in the middle of a transaction with Oracle 10g. And when I restarted my machine and tried to log in, I got the "ORA-01033: Initialization or shut down in progress" error.
I googled regarding this and followed the steps given in the following sites ("Oracle Error and how to fix it (ORA-01033)" and "Getting ORA-01033 when logging in to 9i application") but nothing seems to be working!
This is my SQL trace when I tried to shut down and restart:
SQL> SHUTDOWN ORA-01109: database not open Database dismounted. ORACLE instance shut down. SQL> STARTUP ORACLE instance started. Total System Global Area 171966464 bytes Fixed Size 787988 bytes Variable Size 145488364 bytes Database Buffers 25165824 bytes Redo Buffers 524288 bytes Database mounted.

O/S-Error: (OS 23) Data error (cyclic redundancy check). SQL>
I absolutely have no idea what this says!
Can someone please let me know what exactly is happening here?? Thanks in advance!
