RE: STRDSKRGZ command

Albert - 

We don't do that, but we do regularly balance our Auxiliary Storage Pools based 
on usage traces... 

Every Friday I run these processes during the busiest time of the day:

TRCASPBAL ASP(1) SET(*ON) TIMLMT(600) 
TRCASPBAL ASP(3) SET(*ON) TIMLMT(600) 

Then on Saturday we start balancing based on the trace ran on Friday: 

STRASPBAL ASP(1) TYPE(*USAGE) TIMLMT(1440)
STRASPBAL ASP(3) TYPE(*USAGE) TIMLMT(1440)

Help Text for TRCASPBAL:

                       Trace ASP Balance - Help                      
                                                                     
The Trace ASP Balance (TRCASPBAL) command controls the function that 
gathers the auxiliary storage pool (ASP) usage statistics.  The      
trace function monitors the frequency that data is accessed on the   
disk units within the specified ASP.  The 'high' use data and the    
'low' use data on the units is identified.  The tracing of the usage 
of data on the units can be started on a specific ASP or for         
multiple ASPs.  The trace may be started for a specific length of    
time.  The trace can be stopped by specifying *OFF for the Trace     
option setting (SET) parameter.  The trace can be ended at any time  
and restarted at a later time.  The statistics that are collected    
are cumulative. For example, if the trace is started and ended and   
then restarted without clearing the statistics, the second group of  
statistics are added to the first collection.                        
                                                                     
After statistics have been collected the ASP may be balanced using   
the Start ASP Balance (STRASPBAL) command, specifying TYPE(*USAGE)   
or TYPE(*HSM).  After the balance has run to completion, the         
statistics will be cleared automatically by the balance function.

The balancing of the ASP should be done shortly after the statistics  
have been collected.  The usefulness of the balance is diminished as  
the trace statistics age.  If the statistics are not current, the     
statistics may be cleared by specifying *CLEAR for the SET            
parameter.                                                            
                                                                      
A message will be sent to the system history (QHST) log when the      
trace function is turned on, when it is stopped, or the trace data    
is cleared.

Is anyone using the STRDSKRGZ utility? Is it something that should be run
on a reular basis?
