RE: FourJs and IDS sessions lock

Posted By: Konikoff, Rob (Contractor)

In Response To: Re: FourJs and IDS sessions lock (Jean Sagi)

That's what we do here. I don't have enough skilled operators to run 24x7,
so I (and the Sr. SysAdmin) wrote a script to identify and analyze things.
We identify OS properties (who -u and finger info, commands being executed,
and 4gl/4ge processes that may be active), and then isolate their terminal
session against the onstat -g information to determine if they are running
SQLs (few users allowed!) or have an active thread that is clocking time or
read/writes. The information displayed is enough to tell semiskilled
operators if they have to kill threads against the DB before the user, or
give Sr. Analysts information on who is running critical or resource intense
processes.

The implementation is easy for the basics. It's the Captive User Interface
to keep customers' semiskilled operators from killing things that are
important that provides us the ongoing challenge.

Start with the general ID of all users on the system, id'ing the PIDs
(parent and child of all processes). This allows you to either ID by
processes that are running, or if you know your users, ID by user (that's
the way we do it, since we have the luxury of knowing our users).

Then simply split it up from there... example: Follow the process thread to
the terminal session and match that against the onstat -u information with a
quick and dirty AWK; this, in turn, can be passed to another short snipet to
get onstat -g information or any other relevant information you may need.

At this point, we have guidelines for actual operator decision making on
what to do and what to kill, including a few automated snippets to kill DB
threads before OS threads, look for orphan processes, etc.

Hope these ideas help... they are easier to talk about than to code!

Check for onstat several times to detect changes.

For example onstat -u show you read and writes, that in combination to OS
idle time may tell you if the user is doing something or not. This way you
better decide to kill or not a session.

Subject: FourJs and IDS sessions lock [4294]

Hi

Is there a mechanism either via SQL scripting or anything else which can be
used to identify the user who are really idle from do data manipulation or
processing.


For example :
UserA activate a program call customer. By doing that he/she will get the
program menu and the form. Then he/she leave it the screen open from the
morning till the evening without doing anything. By looking in onstat -g
ses, one session already being created. Since the applcation using FourJs,
it already locked one session of FourJs(this effected the number of FourJs
license used).
One of our client writing the script by looking at OS point of view in term
of idling to kill the user. By that, the FourJs and the Informix session
not clearly release and it lock other user who really want to access the
program.

Can somebody give some clue to rectify this.

Thanks
