Hi all,
Genyphyr is right. On server models of AS400, there is a card for interactive 
processing allowed. It is measured as an % of the CPU used: if you exceed the % 
of interactive jobs working allowed by your license, you get penalized by a 
job(s) call CFINT0x (CFINT01, CFINT02,.. one per processor you have in your 
machine). This jobs have priority 0, and are not seen by WRKACTJOB but using 
WRKSYSACT you see if they are comsuming CPU. And this jobs the only thing they 
do is use CPU. They stop when you reduce the interactive jobs working. They 
slow your machine down.
But, as you say, iddle sessions do not use cpu , just memory, so they wil not 
penalize your system.

I would direct this question to your IBM rep so that they could take into
account your specific to your AS/400 set up and CPW allowances for batch and
interactive work on the system. Whether you are running BPCS or any other
software in this case is irrelevant - just ask about whether or not the idle
interactive jobs are impacting overall system performance. I don't think
your question is BPCS specific - this is more of an AS/400 question.

My guess is that whomever told you this, the advice was aimed at people who
own server models of AS/400s or models with a limited interactive CPW - in
other words, the more interactive jobs you have started, the slower the box
would go (no matter what software you were using on the system) due to IBM
restrictions on the number of interactive jobs it will handle. But this is
just my guess at why someone would have told you this.

You can read the IBM Redbook for implementing BPCS for general system set-up
tips to improve overall BPCS performance. This book is available online from
IBM at the Redbooks site:

Hi,

I was told that the general BPCS system performance can be improved if all
'inactive' or idle sessions are automatically terminated. We do not break
them now because we are afraid of the loss of data consistency. The AS/400
hosting BPCS has a lot of memory (3 GB), the number of open user session is
approx. 50. WRKSYSSTS indicates no memory problems. I c


AS/400 model 8xx, OS/400 5.1, BPCS 6.0.04 plf MM, Client Access Express.

Regards,
