Hi I'm a little rusty with HACMP, but wanted to find out if it is possible to remove a disk heartbeat network from a running HACMP cluster. Reason is, I need to migrate all the SAN disk, so the current heartbeat disk will be disappearing. Ideally, I'd like to avoid taking the cluster down to...

Shared memory for shared library

I am writing a shared library in Linux (but compatible with other UNIXes) and I want to allow multiple instances to share a piece of memory -- 1 byte is enough. What's the "best" way to do this? I want to optimize for speed and portability. Obviously, I'll have to worry about mutual exclusion.

GNOME-DISK-IMAGE-MOU(1) 					gnome-disk-utility					   GNOME-DISK-IMAGE-MOU(1)

NAME

       gnome-disk-image-mounter - Attach and mount disk images

SYNOPSIS

       gnome-disk-image-mounter [--writable] [URI...]

DESCRIPTION

       gnome-disk-image-mounter can be used to set up disk images. Both regular files and GVfs URIs (such as smb://filer/media/file.iso) can be
       used in the URI parameter. If no URIs are given and a window server is running, a graphical file chooser will be presented.

       Note that gnome-disk-image-mounter will not mount filesystems or unlock encrypted volumes in the disk image - this responsibility is left
       to the automounter in GNOME Shell to ensure that the same interactions happen as if the disk image was a regular physical device or disc.

       By default the disk images are attached read-only, use the option --writable to change this.

RETURN VALUE

       gnome-disk-image-mounter returns 0 on success and non-zero on failure.
