Re: Reading a file# that doesn't exist

Tempfiles are numbered from (DB_FILES+1) upward...



Quoting Henry Poras <henry@xxxxxxxxxxxxxxx>:

I have a session on a development system that is waiting on 'db file
sequential read'.

It has been waiting for ~6000 seconds (state=WAITING).

File# (p1) is 201, yet the database only has file#'s from 1-19 (select file#
from v$datafile).

That explains the long wait. It's trying to read from a non-existent file. I
can't connect to strace (attach: ptrace (PTRACE_ATTACH, .): Operation not
permitted).

Has anyone seen this before? Any ideas where to look? Just reboot and try
for the best?

Henry
