>From the time user presses ENTER for the unwanted delete until he submits the batch job (or executes the TSO command) to invoke your new utility, the user in question is going to be performing TSO tasks on his terminal, many of which may allocate new temporary datasets. All the other users are going to be working as normal, including allocation. Ditto for the batch jobs and started tasks. What is your expected confidence level that the tracks used by the dataset have not been reused?
What is the probability that the user will even remember what volume the dataset was on? If not, how will your utility find it? Even if your utility has the correct VTOC, how will it handle the situation where multiple datasets with the same name were allocated and deleted on that volume over the course of time? You could have multiple unused DSCBs with the same DSN. Which is the one to recover? -----Original Message----- From: shai hess Sent: Thursday, July 09, 2009 1:11 AM To: [email protected] Subject: Re: Any product to undelete file? No, I do not think about complicate process which will verify that the data is not overwrite. I think about situation when you press ENTER for delete request and you understand that you make a big mistake. You become hysteric, and you wish you can just run the undelete quickly and return the file to life. This going to be simple process, no backup or any complicate process. If the file is overwrite, just tell the user that you are sorry but part of the file is dead. ByTheWay in PC you have many utilities to recover files, but in PC this utilities can be implement easy. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
