hi,
i used the defrag command present in ADRDSSU.
But , the volume serial is not getting compressed /defragmented
here is a snippet:
DEFRAG DDNAME(DISK1),WAIT(0,0)
DUMP FULL -
IDD(DISK1) -
ODD(TAPE1) -
ALLDATA(*) ALLX OPT(4)
IF MAXCC = 04 THEN SET MAXCC = 00
can anyone help?
Thanks in advance. |

post the sysout please
and .... if You are worried about losing data during the defrag operation
it would be better to run the dump command before the defrag command |

THANKS A LOT.
the sysout is :
THE DEFRAG FUNCTION COULD NOT FURTHER REDUCE THE FREE SPACE FRAGMENTATION OF THE VOLUME.
the volume has 2700 free cylinders but showing only 1450 LgFree Cyls.
I want to further DEFRAG it.
Do we have an alternative for the same? |

Obviously you can not.
DEFRAG will not move allocated or in use files. |

| Is there any other alternative other than DEFRAG command of ADRDSSU utility to compress a DASD? |

| FDR have a similar product FDRCPK (Compaktor) which is far superior to DFdss. |

Can we create jobs using FDRCPK in IDMS to compress a DASD? Is there any kind of document that could help me in creating such jobs?
Thanks in advance |

Allocate an empty volume to your pool. use DFDSS to move all your data over. That'll do the trick. |

caveat being that the present volume is not allocated to some job/stc/tsu of course. |
