Hi All,

I define my dataset with following properties like.

DISP=(NEW,CATLG,DELETE),UNIT=(SYSDA,10),
SPACE=(CYL,(10,10),RLSE),
RECFM=FB,LRECL=350

The above option RLSE will be in affect for CYL or for both UNIT and
CYLINDERS.

Please clarify me.
Thanking you,

Ram.

You did not state the problem or question. If you got an error, post it too.

Whether or not the RLSE will affect both CYL & UNIT depends on the STORCLAS which has been allocated to the dataset via DFSMSsms.

The RLSE should free up all of the unused space across all of the volumes.

There is the possibility that by using SDS ( Sequential Data Striping) the file will be allocated accross all of the volumes specified, and then the RLSE will free the space from each stripe on each volume.

Under normal circumstances the RLSE will release all unused space, but usually retains the number of volumes that it can use, so if the file is added to at a later time, the dataset may still have the ability to use further volumes if the full allocation has not been used.

Thank you very much for your response on my querry.

Can you please share more about option SDS and its syntax.

Thanking you,

SDS is a facility of DFSMSsms. To use this facility you will need to speak to the storage management people.
