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.

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.
