[comp.os.vms] Transaction count on disk devices

     Does anybody know in what units the 'transacion count' of a disk
 device is measured (ref. output of DCL kommand "$ show device d") ?

 Thanks to all of those who responded to my question.It seems indeed that
the transaction count of a disk device equals the number of open files on
that disk (minus the index and the quotafile).
This can easily be verified using '$ show device disk_device/files'.

I've always found that the transaction count is quite close to the number of
files that show up when you do a show dev/files

eg.

show dev d shows dua1 having a transaction count of 50, if you do a show
dev/files on dua1 you should get 50 open files (or so).  This is my
observation, not from dec
