A track on a 3390 type disk has 56,664 bytes. If you multiply the number of tracks (297,141) by that you get 16,837,197,624 or about 16GB.
This is a rough estimate. The actual count can depend on parameters you use to transfer the file, the actual data in the file and other factors. For example, if the file has many blanks at the end of each record, the actual size on your computer will probably by smaller. -----Original Message----- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of Parin Gangar Sent: Tuesday, December 23, 2008 11:08 AM To: IBM-MAIN@bama.ua.edu Subject: How to calculate size of a PS dataset Hi, I need to calculate the size of a dataset in Megabytes / Gigabytes. I cannot download the file and check the same as I know the file size would be over 50 GB and I don't want to fill up my hard disk. The dataset has following details - Device type . . . . :,3390 Record format . . . :,FB Record length . . . :,1526 Block size . . . . :,7630 1st extent tracks . :,15000 Secondary tracks . :,1500 Current Allocation, ,Allocated tracks . :,297,141 ,Allocated extents . :,190 , , , , Current Utilization, ,Used tracks . . . . :,297,141 ,Used extents . . . :,190 I tried searching this on Google, but didn't get anything. I know that there is some formula for this. Any help will be much appreciated.
