I have a number of questions pertaining to ZAP:
1. Does it stop processes using "STOP/ID=" ?
Is there a problem using this in conjunction with certain databases?
I have read somewhere that this could be a problem.
2. What criteria does ZAP use to determine a 'victim process' ?
CPU usage, CPU time, Buff I/O, .... or a combination thereof ?
Can I control these parameters ?
3. Can I set up various classes of 'victims' with different parameters
e.g.
[1,*] - no ZAPPING
[60,*] - ZAP between 18:00 and 06:00
dialup terminals - ZAP after delta time
batch jobs - ZAP after delta time.
The ASSETS description is vague at best.
Sorry if this is in the wrong place, or has been asked elsewhere,
but I'm in a hurry with a bad connection.
Thanks
/Jeff

{Sorry about the delayed response}
1. ZAP uses the DELPRC system service which is the same as using
the "$ STOP/ID=" command. Some applications do have problems
with this and should not be stopped by ZAP. Each application
should be checked.
2. Zap uses Direct I/Os, Buffered I/Os and CPU clock ticks to
determine how much work is performed. The ratio is
(3 * Direct I/O ) + ( 2 * Buffered I/O ) + CPU ticks
You can not change the formula, but you specify how many "units"
must be performed to be considered "active".
3. Zap uses UIC, Image name, Terminal class/name to determine
which "catagory" a user falls in to. Each "catagory" can have
its own time limit or be immune. An "mini" example is below
of the Zap data file:
!UIC Image Terminal Time limit Send Message
[1,*] * console * Nomessage
[200,150] monitor any 15 Message
[200,*] monitor any 30 Message
Etc.
In addition, you specify when the warning messages should be
send and what they should look like.
ZAP V3.8 can be obtained via the ASSETS program from VTX with
the $ VTX ASSETS_OFFICE command.
Thanks for your interest,
