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.

Hi Parin,
the data set has 5 records in each block of 7.630 bytes. A track of 56.664
bytes (assuming 3390 DASD) can contain 7 of your blocks. That are 53.410
bytes per track. The data set has allocated 297.141 tracks, each 53.410
bytes of data. That are 15.870.300.810 bytes (which fit in an
One trick I like to use - go to option 3.2 and allocate the file in MB in
the panel. Then copy the current dataset to this new one and see how much
space was requested in MB. Requires no math. Use the same attributes
except instead of cylinders use MB.

Another approach that could be used if you are not bothered by reading
the whole file is to use ftp and
get mvs.dataset.name nul(Windows)
or
get mvs.dataset.name /dev/null (Linux/*nix)
Windows, for its own peculiar reasons, will also accept nul.xxx where xxx is
some qualifier of your own
We faced this problem recently when implementing MVS dataset support
for SFTP. (The SFTP protocol works much better if the server can
provide at least an estimate of the file size in bytes). It is not
feasible read the entire dataset to find out the size, since the
server provides sizes

Somewhere in here there's an argument supporting keeping one's data
in Unix files rather than Classic data sets. Then FTP's DIR command
would show the file size.
Thanks Dave. Yes, I can get the member selection list to DOWNLOAD multiple
members to the PC but I would like to UPLOAD hundreds of members to the
mainframe. It appears that 3.7.2 doesn't seem to have the capability to do
multiple members. However, this method is quite simple. And thanks,

Download BLK3390 from www.cbttape.org; it will tell you how many blocks
per track for any block size. Then
I also get an error trying to file transfer to a pds from extra and i
specify 'pds(member)' and there is no error code or reason other than
the transfer failed. there are also some other options in the 'folders'
options like 'strip pds names' which do not have any effect.

It runs on windows and you can plug in the attributes and it will calculate the

Bob's estimate sounds about right. The control LPARs don't burn many CPU
cycles. There will be a peak (or multiple peaks - depending) during the day
when the status of the DASD is checked. Depending on how many devices you have,
it is probably a good idea to plan this task for a quiet time. I

Different year... same thread.
I saw a similar thread in the archives from November 2006.
MB to Cyl Conversion
On of the posts said this:
For 3390 DASD:
- A cylinder holds exactly 780 KB (based on 4K blksize no keys)
- to store 1 MB of 4K blocks requires 1.3128 CYLs
- 1 CYL = .76171875 MB
The information from the 2006 post is incorrrect. For a 4K blksize no keys, a
cylinder holds exactly 720K, as DASDCALC says, not 780K.
4096 * 12 blocks * 15 tracks = 737280 = 720K
Also, it is inexact wording to say According to DASDCALC, a cylinder with a
blksize of 4096 is 830K because that
Hi, John,
No, while I have not had any say in how this is all set up, I meant we have
things like Class Max Tasks is set to 1 for many key transactions, in
several AOR regions. Some of the transactions are coded in a way I saw many
years ago that I characterize as running a batch job in a CICS.

I seriously doubt it. You can check
The 4HRA does not change with changes in Defined Capacity. If you raise a
defined capacity value, while WLM is limited the LPAR due to implementing
the defined capacity, then the 4HRA will start raising also. But this is a
