msgmni - maximum number of system-wide System V IPC message queues (IDs) allowed
VALUES
Default
Failsafe
Allowed Values
DESCRIPTION
The tunable specifies the maximum number of system-wide System V IPC message queue identifiers (one per queue). Each message queue created
has an identifier (ID) and there is an upper limit of identifiers.
Applications use the system call to create new queues. If all IDs have been used, will return
If a process acquires a message queue, but the process terminates without removing it, the queue and all its messages remain. Abandoned
message queues can be removed with the command. Message queue status can be monitored using the command.
For more information about System V message queues, refer to the section of the mesg(5) manpage.
Who Is Expected to Change This Tunable?
Anyone.
Restrictions on Changing
This tunable is dynamic. Changes to to this tunable take effect immediately.
When Should the Value of This Tunable Be Raised?
Raise this tunable when applications require more queues.
When Should the Value of This Tunable Be Lowered?
Lower this tunable when the requirement for queues has diminished.
What are the Side Effects of Lowering the Value?
Lowering the value increases the risk of application failure due to the inability to create more message queues. Lowering the tunable has
no effect on any active message queues, even if the new tunable value is less than the number of queues created in the system. However, no
new queues may be created until the number of active queues falls below the setting of
What Other Tunable Values Should Be Changed at the Same Time?
All the System V message queue tunables are interrelated and should be treated as independent variables. The set must be evaluated as a
system to ensure the tunables reflect the application requirements. The message tunables include and Specifically, and tunables may need
adjustment along with changes to the tunable.
