Format 8 . Both formats 8 and 9 show the fully qualified filename or
absolute pathname followed by the accessor summary line (described
below). After the accessor summary line, there is one line of output per
file accessor, consisting of:
• job/session number
• user name
• number of processes accessing, locking, writing and reading the file
• IP address for remote sessions, or the $STDLIST spoolfile ID for job
accessors, or the LDEV number for local session accessors
Following is a format 8 example:
:listfile hppxudc.pub.sys,8
********************
FILE: HPPXUDC.PUB.SYS
15 Accessors(O:15,P:15,L:0,W:0,R:15),Share
#S265 MIKEP.HPE P:2,L:0,W:0,R:2 LDEV: 49
#S263 JEFFV,MGR.JVNM P:3,L:0,W:0,R:3 LDEV: 47
#S261 KROGERS.MPENT P:2,L:0,W:0,R:2 LDEV: 50
#S231 SUSANC.MPENT P:2,L:0,W:0,R:2 LDEV: 46
#S219 FAIRCHLD.MPENT P:2,L:0,W:0,R:2 LDEV: 39
#S214 CATHY,MGR.BOSS P:2,L:0,W:0,R:2 REM : 15.14.16.19

#J434 FTPMON,FTP.SYS P:2,L:0,W:0,R:2 SPID: #O21905
Analyzing the above format 8 example:
1. The filename shown is always fully qualified as it appears in format
6.
2. The line beginning with "15 Accessors…" is the accessor summary
line, which shows the total number of accessors of the file across all
jobs and sessions. This total includes all processes that have
formally opened the file and all processes that have pseudo-opened
the file. This is the same number seen in the FLAGS field when
executing LISTF,3. The total number of accessors may not
necessarily be derived by adding up the individual accessors
displayed. This is because certain file accesses are done without
using the file system and these accesses are transient and difficult to
detect. An example of this kind of access is when STORE
pseudo-opens a file to read its contents to backup.
The "O:" field is the actual number of processes that formally opened
the file (for example, called FOPEN, HPFOPEN, OPEN, or others). The
O: number can be lower than the total number when the file has
been pseudo-opened, as done by STORE. Another factor is that the
system protects certain files at boot time by pseudo-opening them, as
is done on NL.PUB.SYS. Also, a LISTF,8 done at the same time on
the same file as a LISTF,2 (for instance) will show the LISTF,2
users as an accessor that has not formally opened the file. Typically,
however, the O: count and total number of accessors match.
The total number of processes (P:) accessing the file should generally
match the O: count.
