Suppose if 100 tracks are allocated for a dataset and only 30 tracks are utilized, is any way to free up only the 50 tracks from this dataset?

We shall use the F option of 3.4, but that will completely free up all un-used space. We need to maintain few un-used tracks in the dataset to avoid sapce issues as the dataset will be updated priodically.

Provided you have specified secondary allocation when you created the dataset it will grab more space if it needs it so 'F' it anyway. Otherwise the only way is to copy it to another dataset with the space allocated as you require.

Take a look at the RELEASE parameter of DFdss. I can not recall if it allows partial release or not. I know that FDR/COMPAKTOR does.
