Find who is holding your dataset (F1 twice)

Sometimes we face situation where in other user/job is holding your dataset exclusively (in Edit/View mode), in such situation executed job will wait for dataset to become available. But how can we identify if multiple users are there in our project/mainframe system. No worries we have solution for that

Just open the Dataset in question 3.4 and try to open dataset using “V” command that will throw an error saying dataset is in use. Once you see error press “F1” twice and that will show you list of user holding dataset
