Re: Oracle RedoLogs are Full - Now What?
I suspect what has happened is notr that your redo logs have filled (that is normal) but rather you are out of space in your archivelog directory. Let's say that you have four redo logs. When redo1 fills up you switch to redo2; when it fills you switch to redo3; when it fills you switch to redo4; when it fills you first copy redo 1 to an archivelog and then switch to redo1. You need to either remove old archivelogs (after making sure that they are not needed or they are backed up) or create more room in this logical volume.

Re: Oracle RedoLogs are Full - Now What?
what is exact ORA error ?
if it's in that you explain just delete very old archive file (may be previous month) in
"log_archive_dest=" directory as Clay suggest.

Re: Oracle RedoLogs are Full - Now What?
I want to second Clays solution and come with some more information.
On a production database you most certain have set up archiving of the redologs.
When your database became inaccesible, there was no need of shuting it down (infact shuting down should be the last solution when you experience problems, as data might be consistent in memory but due to some error not on disk yet.)
What happens when the archive filesystem gets full is that the archiver backround process stops copying redologs out, and thereby effectively preventing redologs not archived to be reused.
If / when this situation occure, the thing is just to move/delete the archived logs to free up space or to extend archive volume if you have the possibility. The database would then start running all by it self as the archiver starts up and the redologs are freed.
If running with archiving you should implement some routine to atomatically backup and delete the archived redologs, to prevent archive filesystem to filling up.
If using RMAN to do backups you also can use this to backup and delete the archived redologs.

Re: Oracle RedoLogs are Full - Now What?
Thanks to all for your responses and I understand what your telling me. However, after moving the archived logs from one filesystem to another (for backup purposes), leaving our /u06 filesystem empty, I still receive the following when trying to start the database instance:
SVRMGR> startup
ORACLE instance started.
Total System Global Area 80409504 bytes
Fixed Size 38984 bytes
Variable Size 49486680 bytes
Database Buffers 30720000 bytes
Redo Buffers 163840 bytes
Database mounted.
ORA-00255: error archiving log 5 of thread 1, sequence # 83945
ORA-00312: online log 5 thread 1: '/u07/oradata/PRD0/redo51_PRD0.log'
ORA-00312: online log 5 thread 1: '/u09/oradata/PRD0/redo52_PRD0.log'
ORA-00270: error creating archive log
ORA-00334: archived log: '/u06/oradata/PRD0/arch/arch.log'LOG83945_1.ARC''
ORA-07352: sfccf: create error, unable to create file.
HP-UX Error: 5: I/O error
So, is my problem still with /u07 and/or /u09?

Re: Oracle RedoLogs are Full - Now What?
'/u06/oradata/PRD0/arch/arch.log'LOG83945_1.ARC''
mind the quotes within the filename. Please check log_archive_dest_1 and/or log_archive_format for excessive quotes.
Also make sure Oracle has write privilege on these directories.
good luck,
Thierry.

SolutionI think your real problem is with /u06. Unfortunately, errno 5 (EIO) generally indicates a failure reading or writing to a device - possibly a disk failure. You need to unmount /u06 and run fsck on it (and probably not just a log replay). I that is ok try creating a file in the archive directory.
