Dispatchee Stopped ...URGENT

Question

Hi All,
After restarting the computer Dispatcher Stopped working and in Event Viewer it's giving the error below:
ORA-00354: corrupt redo log block header
ORA-00312: online log 4 thread 1: 'E:\ORACLE\DR1\ORIGLOGB\LOG_G14M1.DBF'
ORA-00312: online log 4 thread 1: 'F:\ORACLE\DR1\MIRRLOGB\LOG_G14M2.DBF'
I have also found the note related to this problem....but i dont how to execute this suggestion: Through brtools or from the oracle end....plz explain?
"If the ORA-00354 occurs when you are archiving an online redo log (additional error: ORA-16038: "log cannot be archived" or "ORA-00255: Error archiving log") and not during a recovery, the archiving of the redo log can be suppressed as follows:
ALTER DATABASE CLEAR UNARCHIVED LOGFILE '<log>';
Finally, you must create a consistent backup as soon as possible since a recovery is no longer possible beyond this time because the offline redo logs are missing.
Can anybody tell me how to resolve this issue.
regards,
Amit

Answer 1

Amit,
Try this....Issue the following command on redo log members.
SQL> ALTER SYSTEM DUMP LOGFILE 'filename'
2. If the redo log member is corrupt, then the dump command will fail with the same error as when doing a media recovery with the same file.
3. If the dump of any of the redo log member is successful then,
   a. shutdown the database.
   b. replace the bad member with a copy of the good redo log member using Operating system commands
   c. startup the database
Let me know the result
