[vijay8282]

Hi,

When I look at my ARC1.trc file it tell me

Instance name: SID

Redo thread mounted by this instance: 1

Oracle process number: 76


What do u mean by
Redo thread mounted by this instance: 1


AND

also on chekcing this file i noticed an error

***
Corrupt block relative dba: 0x00000262 file=0. blocknum=610.
Completely zero block found during controlfile block read
***

this error came long back in july (i m new guy here).
now no error is coming.

what should i need to look into...

Could you please check your alert_SID.log file for this instance normally located under $ORACLE_BASE/admin/SID/bdump and post the exact error from the log. This is due to some block corruption on the control file

Could you also post the oracle and os versions too.
