OLD specifies exclusive use of a dataset, SHR allows
multiple jobs to concurrently access the dataset Note: When
updating a dataset, you would normally use OLD.

disp=old means at the time of execution another job can't
use that file.after completion of job another job can use.
disp=shr at the timeof exection many user can use in read
mode.

Read from beginning of dataset. But if u write, then it
will overwrite on existing data. i.e old data is lost.

Answer / sunil
disp= old ...it will give exclusive use of dataset.
disp= shr....multiple job can use the dataset concurrently..
but in both case, while writing , it will overwrite to old
dataset..i.e, old data will be lost.

Answer / anurag
Generally DISP = OLD is used when a Dataset is generated in
a step of job and then subsequently used in the next up
coming steps of the same job ,
DISP=SHR signifies that the dataset is can be shared by the
multiple jobs.
