SolutionA 9GB disk is not very large these days.
> HOW CAN I KNOW WHAT PROGRAM OR PROCESS [...]
Programs and processes don't occupy disk
space. Files occupy disk space. Find the
files, then try to figure out who's making
them.
Big files:
dire /date /owne /size /sele = size = min = 10000 sys$sysdevice:[000000...]
Many versions:
dire /date /owne /size sys$sysdevice:[000000...];-16
Adjust the parameters according to your
situation.

Re: disk space
Ignore any with no process name and a PID of 00000000 and files of type .EXE. Then look at what's left and try to figure out what the files are for.
There's many possible causes (e.g. error log or ACCOUNTNG.DAT expanding) but I'm guessing that you'll probably find a .LOG file, very likely with a high version number, causing the problem.
Of course if you have the appropriate monitoring tools to identify the hot files on the disk your task would probably be much easier.

HELP SET ACCOUNTING /NEW_FILE
Zip can compress these things pretty well, if
you'd like to save the old data. (You'd need
to re-expand it to do any processing, of
course.)

Re: disk space
You may want to do this every week or month.
You may want to use $SHOW ACCOUNT to see what its being recorded, and adjust with SET ACCOUNT as desired.
Please purge the account file only after taking a copy onto an other disk and/or some network storage.
Please google for DFU for a handy tool to find files quicker, and with more options, than DIRECTORY can.
MCR DFU SEARCH/FRAG=MINI=100
MCR DFU SEARCH/SIZE=MINI=1000000
MCR DFU SEARCH/VERS=MINI=20000
:
DFU is also handy to delete directory trees.

Re: disk space
The accounting facility is controlled by the SET ACCOUNTING command. A new file is started by doing SET ACCOUNTING/NEW_FILE from a suitably privileged process. I strongly recommend reading the documentation on the command before doing anything along these lines.
After a SET ACCOUNTING/NEW_FILE, the old file can be reduced in size using the ZIP utility (please remember to use the "-V" switch to preserve the OpenVMS file attributes).
The SHOW ACCOUNTING command will indicate what information is currently being logged. Depending on what is being logged (and what the reason for logging it is) governs whether you can make changes.

Re: disk space
So, when using directory or dfu to find files that have a large amount of disk space allocated, be sure to use the appropriate command to look at allocated size instead of used size.
$ dir/select=size:min:100000 disk$data:[000000...] /size=allocated
$ dfu search /size=min:1000000 disk$datau /sort /allocated

Re: disk space
If it is very fast - a day or two - then check that you don't have image level accounting switched on.
(If you don't know what it is then a quick look at the documentation for Accounting will explain better than I can here.)
It is also possible that the rate at which processes start and, more importantly, stop on your system is particularly excessive.
By the way, I recommend moving your old ACCOUNTNG.DAT files (compressed or not) off the system disk. I'd retain maybe a week or two's worth but no more. Any earlier can go to another disk or better yet, back them up to tape.

Re: disk space
When you "Purge" the disk, how many files are deleted, and how much space is released.
You should also check things like Page Files and Dump Files. Consider moving them off the system disk (if they are there).
Check also to see if you are saving "Recovery Data" from patch installs.
Also, if you have "non-OS" applications installed on your system disk, you should consider researching how to move them off.
