i have to instal a politic of DUMP and RESTORE in a classi production.
I juste want to know how do you do in your site.
For example :
1) Dou you DUMP the dataset at the end of a the TWS application ?
2) Whith ADRDSSU ?
3) When do you delete the dataset ? At the beginning of the TWS application ot at the end with the DUMP/DELETE of ADRDSSU ?
4) How do you restore your dataset ? How do you find quicly the number of the tape to restore ?
Thank's for your answer.
First, "dump" in this context is not the correct word. "Backup" would be a better choice. One seldom "dumps" a single dataset, In this context "dump" applies to multiple, usually unrelated datasets.
Second, "TWS application" is basically meaningless. TWS is a job scheduling system.
Third, using ADRDSSU to backup a dataset (or more likely a group of related datasets) into its "dump" format is certainly possible, but not advised.
Fourth, you do not delete a dataset before you back it up. The only common exception to this rule is many JCL defined jobs conditionally delete a dataset and then reallocate it, with the implied context that there is already a viable backup of the dataset.
Fifth, when you backup a dataset, and the tool used to perform the backup is immaterial, you are creating a new dataset. You catalog this new dataset, so if you need to restore the dataset contained in the backup dataset you refer to the backup dataset as a cataloged dataset in the usual way.
