Operating Systems AIX which setting defines behaviour when paging space runs full ? Post 302445318 by zxmaus on Sunday 15th of August 2010 08:54:30 AM

which setting defines behaviour when paging space runs full ?

Hi,

I have a bunch of AIX systems which usually have more than enough memory to live happily. Unfortunately we have on a few of our boxes an rman runaway problem - every now and than after restoring from rman backups, the process goes crazy and eats all memory it could possibly get hold off - sometimes 100 gig and more just in a couple of minutes ... and oracle cannot find the root cause for this for months ...

Since this happens to real business critical DB boxes, my question: does anyone know which memory setting is responsible for the behaviour on an AIX 5.3 lpar when paging space runs full?

I have a few boxes that recycle themselves, others start just forking / hanging / killing randomly processes to survive - where is no point as AIX usually thinks killing the DBs is a great idea - so a system restart would be my preferred behaviour as this is anyways what I have to do when the box hangs - and the boxes that do it themselves save me a lot of paperwork / hazzle - and are usually fine for months afterwards Smilie

I know I know - solving the problem should be highest priority and we are working on it - but until than ... I want restarts Smilie

Kind regards
zxmaus

AUTOLOG(8)						      System Manager's Manual							AUTOLOG(8)

NAME
autolog - Log out idle users SYNOPSIS
autolog [ options ] DESCRIPTION
The program reads the utmp file, entry by entry. The username for each 'user process' is compared to the entries in the configuration file (see autolog.conf(5) ). The first entry to match both the name, the group, and the tty line of the process will be used to conduct the automatic logout. CALL
/etc/init.d/autolog start or autolog to run this program in daemon-mode autolog -o to run this program as "ordinary" program. Keep in mind: Also when running as ordinary program, it will stay in memory until all its jobs are done. OPTIONS
-a (all processes) Print information on ALL utmp entries--not just user processes. -d (debug mode) This is helpful in setting up your configuration file. The program runs in foreground rather than forking and it prints out verbose messages about what it is doing. -n (nokill) Use this to prevent autolog from actually "killing" anyone. Use -d and -n together when setting up a new configuration file. ( This will not affect killing of lost processes. ) -o (ordinary) Use this to run this program as ordinary program, not as daemon. Program will end, when its job is done. In this case, some data is kept in "/var/lib/autolog/autolog.data". This is read, when the program is called again. -f config_file_name Use this to override the default: "/etc/autolog.conf" -l log_file_name Use this to override the default: "/var/log/autolog.log". Note that if this file doesn't exist, no logging will happen. Create the file (with touch) to enable logging. -t idle_time Use this to override the internal default idle time (minutes) -g grace_period Use this to override the internal default grace period (seconds) -m yes/no Use this to override the internal mailing switch. If "yes" the program will send mail to the users right after killing them. -c yes/no Use this to override the internal "pre-clear" switch. If "yes" the program will clear the terminal screen before warning the user. -w yes/no Do timeouts based on total session time--not idle time. (hard) -l yes/no If set to "yes" activities will be written to the logfile if present. AUTHOR
