This knowledge document provides instructions on how to verify if the Dynamic Extend option is activated within CA 11.
First, execute a full CXX Report
//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 *
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
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.
