How can I reduce the cycle time for PMO? This is a performance issue.

Environment

z/OS

Resolution

Solution RI49285 has all the documentation for the enhancement to XSYS and the CYCLE parameter. The APAR RO48418 contains the required code update.

-On page 80, the description in "CYCLE Parameter" section is changed from:
                                                                         
   Time interval, in seconds, where 10 < = x = > 1. Consider changing    
   the value only if you feel it is taking too long for updates          
   to be migrated across systems.                                        
                                                                         
 To:                                                                     
                                                                         
   Time interval, in seconds, where 10 > = x > = 0.1. The value lower    
   than 1 second is specified by a decimal point (which may be optionally
   preceded by a zero character), followed by a single digit. Consider   
   changing the value only if you feel it is taking too long for updates 
   to be migrated across systems.                                        
                                                                         
-On page 113, the description in "Changing the Interval That PMO/XSYS    
 writes to the Control File" section under "CYCLE=x" heading             
 is changed from:                                                        
                                                                         
   Tells PMO/XSYS to write to (and read from) the control file           
   every x seconds, where 10 = x = 1. Lower this value only if you feel  
   it is taking too long for updates to be migrated across systems.      
                                                                         
 To:                                                                     

  Tells PMO/XSYS to write to (and read from) the control file            
  every x seconds, where 10 > = x > = 0.1. The value lower than 1 second 
  is specified by a decimal point followed by a single digit. Lower this 
  value only if you feel it is taking too long for updates               
  to be migrated across systems.
