These are two types IPC facilities. IPC (Inter Process Communication) allows two or more processes to talk with one another. They both require space in kernel tables if they are to be successfully allocated. That's where the SysAdmin comes in. He or she must ensure that there is room for all the IPC's that the system needs.

One example is a relational database management system such as Oracle or Sybase. A RDBMS might have one server program that actually talks to the disk drives. And it would have multiple client programs that need to use the database. The programs communicate via IPC's. And when you install Oracle or Sybase, one of the steps is to review the kernel IPC parameters. They usually will need to be increased.

Shared memory in shared library

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)

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. (0 Replies)

This module is part of the Fennec project. See Fennec for more details. Fennec is a project to develop an extendable and powerful testing framework. Together the tools that make up the Fennec framework provide a potent testing environment. The tools provided by Fennec are also useful on their own.
