CA1 records block size and how many blocks. Then you can calculate the size of the file. What type of tape are you using, and are you trying to use tape efficiently, i.e. no wasted space on tape?

Using the TMC gives you the a calculated value as to the amount of data stored. Since this does not take into account compression it does not show the amount of physical tape cartridge consumed.

Re: Method to measure usage of a physical tape
Victor, Within CA 1 there are a number of fields you can use. If it is a physical tape however, the best field to use is the Percent Utilization field. This is extremelly accurate for 3590-emulated devies (3590's, 3592, TS11x0's). This tell the exact percentage of the tape that has been used. So, once a tapes gets beyond 90 or 95% full you might want to stop adding additional data to it.

Does TMS software record this? The topic is not easy because of compression. Your TMS (RMM, CA-1, other) should show you both the length (in MB) of the datasets on the tape as well as total length(in MB) of all data recorded (all datasets). Due to compression it is ambigous what the last number mean: is is number of megabytes sent from the host (uncompressed) or number of megabytes written to the physical tape (compressed)? And, of course, we cannot predict what the compression ratio will occur (exactly). Effect - you can assume compression 3:1, record 150% of physical capacity and have 50% of tape free. Or it can be 30% due to character of data recorded (worse compression). Or have better compression and 80% free. Last, but not least the data which are be appended can have other compression. For RMM you have the following: volume usage [kB] - total bytes written to the tape, uncompressed. Can be more than native capacity. percent full - how much of physical tape track(s) are in use. for any dataset: number of blocks x blocksize For single file tape number_of_blocks x blocksize = volume_usage -- Radoslaw Skorupka Lodz, Poland -- Treść tej wiadomości może zawierać informacje prawnie chronione Banku przeznaczone wyłącznie do użytku służbowego adresata.

Re: Method to measure usage of a physical tape
Victor, Radoslaw already mentioned some of the data that rmm records, and I know CA-1 does similar. However, rmm actually now has much more and very interesting data about what is written by the app and what has happened to it in the hardware. For the details you need to be using tapes that report to the host system the correct information.. So that includes IBM drives since 3590, and other manufacturer drives that correctly emulate 3590. See this section in the rmm MURM http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/dgt2r3a0/1.3.11?SHELF=all13be9DT=20110602105512 This was new capability introduced via an APAR to rmm at the time of TS1140 support - so should be available on all supported releases.
