 Description:

This knowledge document provides instructions on how to verify if the Dynamic Extend option is activated within CA 11. 

 

 

Solution:

First, execute a full CXX Report

Example:

//STEP1  EXEC PGM=DBUTLTY,REGION=4M             

//STEPLIB  DD DISP=SHR,DSN=ABC.AD.R1400.CAAXLOAD

//         DD DISP=SHR,DSN=ABC.AD.R1400.CUSLIB  

//CXX      DD DISP=SHR,DSN=ABC.AD.R1400.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                      

//                                             

 

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.  

                                                     

Note:  If DYNAMIC EXTEND is set for NO, and you would like to activate the feature, please logon to support.ca.com and open a case and a technician will advise you on how to proceed.
