RE: kill idle session

Posted By: Aurelio DE LISIO

hi Lu,

Try this as alternative to API task [checked in IDS11.50]:

SELECT s.sid,

dbinfo('UTC_TO_DATETIME',s.connected) connect_tm,

dbinfo('UTC_TO_DATETIME',t.last_run_time) last_run_tm,

DBINFO('UTC_CURRENT') - t.last_run_time idle_tm
FROM sysmaster:syssessions s,

sysmaster:systcblst t,

sysmaster:sysrstcb r
WHERE t.tid = r.tid
AND s.sid = r.sid
;

It returns idle_time in seconds

Lu:

You should be aware that such a task already exists in the sysadmin database ph_task table. The function is idle_user_timeout(). The timeout period is set in the ph_threshold table and defaults to 60 seconds:

> select * from ph_threshold where task_name = 'idle_user_timeout';

id 6
name IDLE TIMEOUT
task_name idle_user_timeout
value 60
value_type NUMERIC
description Maximum amount of time in minutes for non-informix users to be idl

e.

1 row(s) retrieved.

You just have to enable the task and set its periodicity. As far as your actual question:

> select * from syssessions where sid = 49989;

sid 49989
username art
uid 1000
pid 8002
hostname galadriel-ii
tty /dev/pts/1
connected 1487762864
feprogram /opt/informix/infmx.12.10.FC8WE/bin/dbaccess
pooladdr 1979437120
is_wlatch 0
is_wlock 0
is_wbuff 0
is_wckpt 0
is_wlogbuf 0
is_wtrans 0
is_monitor 0
is_incrit 0
state 524321
