Hi,

ASG recently provided fixes to eliminate use of user key common storage
by TMONCICS.  Past due but well done this provided not only a storage
key change but leveraged MVS/ESA technology to eliminate some common
storage use.  Kudos to the TMONCICS development team for doing a
complete job while they had the code open! 

PTF TH02641

Resolution:                                               
The PTF reworks the use of the secondary addressing mode  
cross memory technique replacing it with access register  
mode usage in the Cross System Monitor.  This change      
removes much the need for CSA storage and CSA resident    
programs. Remaining required CSA areas are allocated and  
updated using storage protect key 0.  SRB related CSA     
storage is allocated for the life of the SRB only.  No CSA
workarea is required for tce session or system tasks. With
the related updates to the LTSS200 via PTF level TQ01787  
and the associated TH02650 and TH02651 PTFs, the TMON for 
CICS/TS system no longer uses CSA storage in any user     
storage protection key, and now has a minimal CSA/ECSA    
storage requirement.  

DEPENDENCY:                                         
    The Specific PTFs required for the LTSS200 FMID are:      
                                                              
    TQ01784                                                   
    TQ01787                                                   
                                                              
    Be sure the LMKLOAD dataset used for your ASG-TMON for    
    CICS/TS product has this minimum service level installed. 

DOCUMENTATION:                                                
    This is one of a set of three PTFs that remove the use of 
    user key CSA storage by the TMON for CICS TS product.     
    The three PTF's are:                                      
    TH02641 - Updates to CSM region Modules (this PTF)        
    TH02651 - Updates to CICS resident DCS Modules            
    TH02650 - Updates to LFS Modules

TMONI0001W - Z/OS 1.8 COMPATIBLE OPERATION REQUIRES TSS PTF
TQ01787                                                    
                                                           
Reason: The support for removing use of user key CSA is    
applied to the Cross System Monitor, however, the          
corresponding support PTF TQ01787 (or later) has not been  
detected. The CSM will still operate normally if user key  
CSA allocation is allowed, however, some user key CSA      
allocated on behalf of the TCE product by The LTSS200      
function will still exist. If the z/OS 1.8 option to       
prevent allocation of user key CSA is in place the CSM will
fail when the user key CSA allocation attempt is made.     
User Action: Apply the required Strategic Services PTF     
level and restart the Cross System Monitor.
