Processes can communicate with each other by using one of several types of interprocess communication (IPC). IPC allows information transfer or synchronization to occur between processes. The resource controls facility provides resource controls that define the behavior of the kernel's IPC facilities. These resource controls replace the /etc/system tunables.
Obsolete parameters that are used to initialize the default resource control values might be included in the /etc/system file on this Oracle Solaris system. However, using the obsolete parameters is not recommended.
To observe which IPC objects are contributing to a project's usage, use the ipcs command with the –J option. See How to Use ipcs to view an example display. For more information about the ipcs command, see ipcs(1).
