One suggestion I would like to make. When a dataset is deleted, a very tiny EOF record is written to each track. Just enough so the actual dasd unit erases all records on that track. If we were still using real 3390s, I would suggest a track full of EOF records. And not an intensive rewrite of the track like ICKDSF TRKRMT or the current VSAM ERASE would do.
If you specify "erase on scratch" in RACF it will erase each track when the dataset is deleted. I assume there is equivalent support in the other security products. You don't need to write a track full of EOF's, if you issue a write count key and data command it will erase the rest of the track anyway, or you can just use the erase command. -- Richard ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
