The following will return (dummied data below for an example :
IPC status from /dev/mem as of Thu May 27 08:37:25 EDT 2010
T ID KEY MODE OWNER GROUP NATTCH
Shared Memory:
m 2097152 0x4500f020 --rw-rw-rw- root system 973
m 1048577 0xffffffff --rw-rw---- root system 1
m 1048578 0x78000179 --rw-rw-rw- root system 1
m 3 0xffffffff --rw-rw---- root system 1
m 4 0xaceb9d2b --rw-rw---- dgoble system 0
m 5 0xffffffff --rw-rw-rw- root system 972
m 6 0xffffffff --rw-rw-rw- root system 43
If you see a key with 0xace and NATTACH of 0 this is an abandoned shared
memory process.
To release this you can either
A) reboot your system
B) Run the following command at Unix
ipcrm -M 0xaceb9d2b
The replace 0xaceb9d2b with the KEY on your system.
Good luck,
-Dan

Dave,
You didn't specify the operating system. I know Windows won't let you resize
the file if it is open. Our application opens the files during login. To
overcome this, I log into the UV account and create an F-pointer to the file,
then resize through the F-pointer. Alternatively, rename your login paragraph
so files aren't opened.

Subject: [U2] Can't RESIZE some files
We are trying to use RESIZE * * * on a couple of dynamic files to reclaim
unused disk space. RESIZE complains that it hasn't got exclusive access, even
though LIST.READU EVERY shows no locks at all, fuser -u shows no one using the
.30 files, and UniVerse (10.0.16) having been stopped and started. We can
resize other dynamic files with no problems. There's plenty of room for the
temporary files.
How can we persuade RESIZE that these files aren't open ?
Thanks,
