Home -> Community -> Mailing Lists -> Oracle-L -> Re: Archival Freeze - Painful lessons learned
After reading the other postings I better add this one too;^) (If ya didn't learn something new today, it's because ya didn't do anything today).
ORA-00257, "archiver error. Connect internal only, until freed."

As Daffy Duck says -> http://www.dailywav.com/0700/dcorrect.wav
The archiver freaks first, and will keep trying to write/recover/looking for space. But the database will not hang until all the redo logs are full and none remain that have been archived (ie: all redo logs need archiving).
The error in the alert.log is some combination of:
ORA-00255, "error archiving log %s of thread %s, sequence # %s" ORA-00270, "error creating archive log %s" ORA-19504, "failed to create file \"%s\"" ORA-27040, "skgfrcre: create error, unable to create file"ARCH: Archival stopped, error occurred. Will continue retrying SVR4 Error: 5: I/O error
Why do I have a list of the above errors you ask? Because I've been there
(painful lessons learned), and these are just some of the errors I look for
in my db status script.

Please respond
to ORACLE-L
Hi Fellow DBAs,
I and a fellow DBA are currently debating about how insufficient space in the archive destination freezes up the DB. He claims that as soon as the ARCH process is unable to write to the disk, the db freezes. I am of the opinion that it does not. It will only report an error (Any idea, what the error code is?). It will only freeze when it cycles thru the rest of the redolog groups, and then when it tries to switch log to the one which has not been archived. That's why the error message is "cannot allocate new log".
Whats your say? He's also on this list.
