    PRODUCT:

    CMF MONITOR


    APPLIES TO:

    CMF MONITOR - all supported versions



    QUESTION:

    We have activated the IPM component in CMF MONITOR and we are seeing the following messages in the MVSPAS log, regarding the CACHE parameter that has been enabled:

    CMFCAC75E IDCSS01 COUNTS CALL FAILED FOR ALL SUBSYSTEMS: RC=0038

    What could be a cause of this, and how to fix it?


    ANSWER:

    Short answer: Please try running the MVSPAS with REGION=0M 

    The help for message CMFCAC75E directs you to review the return codes from the IDCSS01 API:
                                                                                
    TEXT     IDCSS01 xxxxxx call failed for all subsystems: RC=yy. CACHE xPM    
             sampler CAxH                                                       
                                                                                
    REASON   A call to IDCSS01 to request performance data or sense status      
             data failed in a CPM or IPM (xPM in the message) cache sampler.    
             The return code (RC=yy) describes the nature of the error.         
                                                                                
             This IDCSS01 call was intended to obtain information for all       
             sub-systems.                                                       
                                                                                
             'CAxH' identifies the cache sampler that produced this message.    
             Note that there are multiple cache samplers. Each collects data    
             for a different control unit model and each has a different        
             identifier CAxH.                                                   
                                                                                
             Information about the return codes can be found at the end of      
             SSGARGL - argument list obtained from IDCDF70 macro.               
                                                                             
    SYSTEM   If the IDCSS01 call is for COUNTS data, no SMF records for this 
    ACTION   interval are produced for all subsystems belonging to this      
             model.  If the IDCSS01 call is for STATUS data, the SMF record  
             for this interval is not produced for the particular subsystem  
             encountering this error.                                        
                                                                             
    USER     Contact BMC Support.                                            
    ACTION                                                                   
                         
                                                       
     
    The codes are return codes from the IDCSS01 API and are listed in the manual "z/OS DFSMSdfp Advanced Services"

    From there, we can see that code 0004 is GETMAIN failure::
                                                                             
    RETURN CODES FROM IDCSS01
    ====================================================================================
    LEN TYPE VALUE NAME DESCRIPTION
    ===== ========= ================= =============== ===============================
    2 NUMB HEX 0000 SS01CC00 SUCCESSFUL COMPLETION
    2 NUMB HEX 0004 SS01CC04 GETMAIN FAILED
    2 NUMB HEX 0008 SS01CC08 I/O ERROR OCCURRED


    So please try increasing the storage available to the MVS PAS, by increasing REGION=, ideally to REGION=0M
