I need to create a shared library to access an in memory DB. The DB is not huge, but big enough to make it cumbersome to carry around in every single process using the shared library. Luckily, it is pretty static information, so I don't need to worry much about synchronizing the data between... (12 Replies)

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. (0 Replies)

st - shared tape administration SYNOPSIS
device_file DESCRIPTION
The command provides users with a command-line interface to check the status of a shared tape device or to reclaim a shared tape device from a host system that has failed while holding a reservation on the shared tape device. The command can also be used for the same pur- pose on shared library robotic devices. To use the command you must have root user id. Please see examples below for usage. Options recognizes the following options and arguments: Specifies the tape device file or sctl/esctl pass-through device file for the shared tape/library device. This parameter is mandatory and will report an error if device_file is omitted. Allows the user to reclaim a shared tape device or shared library robotic device in the case where a host failed while holding a reservation on the shared device. This option causes a bus device reset to be issued to the device specified by the option. Prints out the current status of the shared tape/library device specified by the option. RETURN VALUE
returns 0 upon successful completion and 1 otherwise. EXAMPLES
The following shows three examples of output from the above command. The above output indicates that the shared device is reserved by another host and is therefore unavailable at this time. The above output indicates that the shared device is not ready for use at this time. The above output indicates that the shared device is ready for use at this time. To reclaim a shared tape/library device from a failed host, the following command can be used: WARNINGS
The option must be used with care. When reclaiming devices, it must be ensured that the host from which the device is being reclaimed has in fact failed, as data may be lost as the result of reclaiming a device that is currently in use by another host. AUTHOR
