System V Message Queues

System V message queues provide a message-passing interface that enables the exchange of messages by queues created in the kernel. Interfaces are provided in the Oracle Solaris environment to enqueue and dequeue messages. Messages can have a type associated with them. Enqueueing places messages at the end of a queue. Dequeuing removes the first message of a specific type from the queue or the first message if no type is specified.

For detailed information about tuning these system resources, see Chapter 6, About Resource Controls in Administering Resource Management in Oracle Solaris 11.4.
