One reason to use ASPs is to improve save file and virtual disk performance. Another reason is to allow more spool to be kept on the system. The is an aggregate total of 2.6 million spooled files hat can be kept in *SYSBAS, but every independent ASP can hold 10 million more.

I have always used one ASP because it is simpler. What is the benefit of running more than one? Thanks, Albert ----- Original Message ----- From: "Graap, Kenneth" To: "Midrange Systems Technical Discussion" Subject: RE: STRDSKRGZ command Date: Fri, 6 Oct 2006 14:21:30 -0700 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. For more information about ASP balancing, see the Hierarchical Storage Management Use, SC41-5351. -----Original Message----- From: midrange-l-bounces@xxxxxxxxxxxx [mailto:midrange-l-bounces@xxxxxxxxxxxx]On Behalf Of Albert York Sent: Friday, October 06, 2006 1:59 PM To: midrange-l@xxxxxxxxxxxx Subject: STRDSKRGZ command Is anyone using the STRDSKRGZ utility?
