RE: PTF needed?

A little further along in that same manual:
The new server algorithm only applies to the new hardware available in V4R5 (2xx, 8xx, and SBx models). The behavior of all other hardware, such as 7xx models, is unchanged.

Our is a 9406-720, and both of the system values you mention are set to '1'.  I've not noticed a CFINT job in any of the subsystems (should I?), nor do I remember seeing one in our earlier release.

Tom,
 
Your  current machine may be undersized for Interactive use.  The following  change in V4R5 describes how Interactive use is now handled.  If your  interactive feature is small and you run heavy interactive, then you would have  seen CFINT very active on you r 4.3 system.  V4R5 changed that to the  message you are seeing on QSYSOPR. One thing you would see under V4R5 is  the priority of the interactive tasks moving from a 20, to a 36, to a 45, up to  a 89.
 
There  are two new System Values options that set by default:   QDYNPTYADJ  and QDYNPTYSCD set to a 1.  These control the limit on Interactive use  according to the feature card installed and throttle Interactive use by changing  the priority and displaying the message you are getting..  If these options  are set to 0 then CFINT will kick in and Interactive could use all of the  processor. 
 
New in  V4R5.  Download the manual from IBM's Publib Web Site --- "AS400  Performance Capabilities Reference".  Chapter 2 explains the changes in the  Interactive environment.
 
Excerpt from the manual:
 
"In  V4R5 there are several new 2xx, 8xx and SBx model servers.  These new  server models utilize an enhanced server algorithm that manages the interactive  CPU utilization.  This enhanced server algorithm may provide significant  user benefit.  On existing models, when interactive users exceed the  interactive CPW capacity of a system, additional CPU usage visible in one or  more CFINT tasks, reduces system capacity for all users including  client/server.  New in V4R5, the system attempts to hold interactive CPU  utilization below the threshold where CFINT CPU usage begins to  increase."
 
Quite  a nice technical explanation in the manual.

We recently  upgraded our 720 from v4r3 to v4r5.  Now we're seeing lots of messages  telling us that we've our interactive threshold (never happened at v4r3 or  earlier).  Anyone know of a PTF to address this issue?
