I noticed the following in one of my alert.logs:

ARC0: Beginning to archive log# 7 seq# 10902 Tue Jan 14 20:04:15 2003

From which I gather that the ARC0 process is stepping on the ARC1 process's toes. What I dont understand is why there are 2 arc processes running, nothing is specified in the init.ora file and I thought the default was 1 process, unless I'm mistaken.

I've enabled some tracing with alter system set log_archive_trace=127 and will see what that tells me (got this sugg. from someone elses thread back in aug)

Should I add a log_archive_max_processes param in the init.ora anyway, just so this doesnt happen again?
