Resolution

Follow the steps below to verify if Dynamic Extend option is activated within CA 11

1.  First, execute a full CXX Report -- See sample JCL below:

       //STEP1  EXEC PGM=DBUTLTY,REGION=4M             
    //STEPLIB  DD DISP=SHR,DSN=YOUR.DATACOM.CAAXLOAD
    //         DD DISP=SHR,DSN=YOUR.DATACOM.CUSLIB  
    //CXX      DD DISP=SHR,DSN=YOUR.DATACOM.CXX     
    //SYSPRINT DD  SYSOUT=*                         
    //SYSOUT   DD  SYSOUT=*                         
    //SYSPUNCH DD  DUMMY                            
    //DDSNAP   DD  SYSOUT=*                         
    //SNAPER   DD  SYSOUT=*                         
    //SYSUDUMP DD  SYSOUT=*                         
    //SYSIN    DD  *                                
      COMM OPTION=STATS,DBID=601                    
      REPORT AREA=CXX,DBID=601                      
    //         

2.  Next, view the output and to the right of the INDEX Information - IXX, you will see the following:

    DYNAMIC EXTEND -    YES 
    DYN.EXT.TRACKS -    15

    INDEX INFORMATION
    DEVICE TYPE - 3390                DYNAMIC EXTEND - YES
    BLOCK LENGTH - 4,096           DYN.EXT.TRACKS - 15
    LEVELS -  1                               OLDEP          - YES
    BLOCKS/TRACK - 12 

 

If DYNAMIC EXTEND is specified as YES, this is the number of tracks that will be used in the DYNAMIC EXTEND.  This does not include a utility extend.  If DYNAMIC EXTEND is specified as YES and this is zero, the VTOC secondary allocation is used.
