RE: Performance problems after upgrading to V4R5 -- MIDRANGE-L

I have found from experience that an upgrade beyond V4R4 tends to have a 
performance impact on heavily used systems - particularly those low on 
memory,  I would suggest that if these systems have any less than 192MB 
that you upgrade them - to 224MB or 256MB or more if posible.
For V5R1 I'm not sure yet, but SUSPECT 256MB may be a minimum 
recommendation, which means some earlier RISC models that can't go beyond 
192MB or 224MB, and are fairly heavily utilized, should seriously consider 
whether they want to go to V5R1 or not.
For V5R2 IBM has made the decision for you on some first generation RISC 
models - they won't run V5R2.

We upgraded from V4R2. This is the fourth system we have upgraded. The
memory and processor group varies. 

Where would I find the latest DB grou ptfs?

Thanks,

                 Albert,

                 What release did you upgrade from, how much memory is on 
the 170,
and what 
                 processor feature does it have ?
                 I presume the latest PTF cum package and database group 
PTF's have
been 
                 applied ?

upgrading to V4R5


                 Has any experienced any performance problems after 
upgrading to
V4R5? We
                 have a 170 which we upgraded on Sunday. Today the users 
are
complaining 
                 that
                 it is seriously slower than before (30 second response 
time). We
have had
                 similar problems with another 170 that we upgraded but 
not as bad as
this.
